Safety Instructions for Pruning Saws

General Pruning Saw Safety Warnings

• Keep all parts of the body away from the saw chain when the pruning saw is operating. Before you start the pruning saw, make sure the saw chain is not contacting anything. A moment of inattention while operating the pruning saw may cause entanglement of your clothing or body with the saw chain.
• Hold the power tool by insulated gripping surfaces only, because the saw chain may contact hidden wiring. Saw chains contacting a "live" wire may make exposed metal part of the power tool "live" and give the operator a electric shock.
• Wear safety glasses and hearing protection. Further protective equipment for head, hands, legs and feet is recommended. Adequate protective clothing will reduce personal injury by flying debris or accidental contact with the saw chain.
• Always keep proper footing and operate the pruning saw only when standing on a fixed, secured and level surface. Slippery or unstable surfaces such as ladders may cause a loss of balance or control of the saw.
• When cutting a limb that is under tension, be cautious of spring back. When the tension in the wood fibers is released, the spring-loaded limb may strike the operator and/or throw the pruning saw out of control.
• Use extreme caution when cutting brush and saplings. The slender material may catch the saw chain and be whipped toward you or pull you off balance.
• Carry the saw by the handle with the saw switched off and away from your body. When transporting or storing the saw, always fit the guide bar cover. Proper handling of the saw will reduce the likelihood of accidental contact with the moving saw chain.
• Follow instructions for lubricating, chain tensioning and changing accessories. An improperly tensioned or poorly lubricated chain may either break or increase the chance for kickback.
• Cut wood only. Do not use the pruning saw for any other purpose. For example, do not use the pruning saw to cut plastic, masonry or non-wood building materials. Using the pruning saw in these incorrect ways could result in serious damage to you and your tool.
• Keep guards in place. Protective guards should be checked periodically to ensure they are properly fitted and in correct working order.
• Do not grasp the exposed cutting blade or cutting edges when picking up or holding the saw. Be sure to encase the cutting bar in its protective sheath when not in use.
• This saw is not intended for tree felling. Use of the saw for operations different than intended could result in serious injury to the operator or bystanders.

Causes and operator prevention of kickback

Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut.

Tip contact in some cases may cause a sudden reverse reaction, kicking the guide bar up and back towards the operator.

Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator.

Either of these reactions may cause you to lose control of the saw which could result in serious personal injury. Do not rely exclusively upon the safety devices built into your saw. As a pruning saw user, you should take several steps to keep your cutting jobs free from accident or injury.

Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

• Maintain a firm grip, with thumb and fingers encircling the saw handle and position your body and arm to allow you to resist kick-back forces. Kick-back forces can be controlled by the operator, if proper precautions are taken. Do not let go of the saw.
• Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the unit in unexpected situations.
• Only use replacement bars and chains specified by the manufacturer. Incorrect replacement of bars and chains may cause chain breakage and/or kickback.
• Never use a dull or loose chain. Keep the chain sharp and properly tensioned.
• Follow the manufacturer's sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback.

Additional safety instructions for Pruning Saw

• The pruning saw is designed for cutting branches. Only use the pruning saw as indicated in this manual for cutting wood. The machine has not been designed for continuous, professional use.
• Keep the pruning saw out of reach of children. It is not a toy.
• Persons with limited physical, sensorial or mental abilities are not allowed to use the pruning saw, unless they are supervised for their safety by a qualified person or are briefed by the responsible person how to use the machine.
• Children and adolescents are not allowed to use the pruning saw. Excluded from this prohibition are young people over 16 years of age under the supervision of an expert for the purpose of training.
• Please note the warning symbols. They mark all those instructions which are important for safety reasons. Observe these instructions as failure to do so could result in serious injury!
• The pruning saw must be used only by one person at a time. Make sure bystanders do not stay in the vicinity of the pruning saw's work area.
• Check the safe operating condition of the pruning saw, in particular the guide bar and the saw chain, before each operation.
• Always have a safe stand when working with the saw.
• Hold the machine firmly and securely when switching on.
• Make sure the guide bar and the saw chain must be free when switched on and must not come into contact with the workpiece to be cut.
• Keep your hands away from the sawing area. Do not reach under the workpiece. Contact with the saw chain may result in injury.
• Guide the pruning saw onto the workpiece only when switched on. Otherwise there is a risk of kick-back if the saw chain gets caught in the workpiece.
• When sawing, the base plate must always face against the workpiece. The saw chain can become jammed and lead to loss of control over the machine.
• When the cut is completed, switch off the machine and then pull the saw chain out of the cut only after it has come to a standstill. This way you can avoid kick-back.
• Clamp the material to be processed well. Do not support the workpiece with your hand or foot. Do not touch objects or the floor with the saw running. Danger of kickback.
• When sawing converted timber and thin branches always use a strong support, such as a sawing trestle. Do not stack timber pieces.
• Before cutting logs, secure the logs in position.
• When working on sloping ground, make sure to work facing upwards.
• Be particularly careful when cutting splintered wood. Splinters of wood can be torn along by the saw chain and increase the risk of injury!
• Foreign objects such as nails, screws, metal parts, sand, etc. lead to increased wear on the guide bar and saw chain.
• A blunt saw chain can cause overheating and damage to the motor.
• Always remove the battery when checking the chain tension, to re-tighten it, to mount the saw chain and to eliminate faults! Also remove the battery if you do not use the machine temporarily.

Battery & Charger Safety Instructions

We pay a great deal of attention to the design of every battery pack to ensure that we supply you with batteries that are safe, durable and have a high energy density. The battery cells have a wide range of safety devices. Each individual cell is initially formatted and its electrical characteristic curves are recorded. This data is then used exclusively to be able to assemble the best possible battery packs.

Information about the battery

1. The battery pack supplied with your cordless pruning saw is only partially charged. The battery pack has to be charged completely before you use the tool for the first time.
2. For optimum battery performance, avoid low discharge cycles by charging the battery pack frequently.
3. Store the battery pack in a cool place, ideally at 77°F (25°C) and charged to at least 40%.
4. Lithium-ion batteries are subject to a natural aging process. The battery pack must be replaced at the latest when its capacity falls to just 80% of its capacity when new. Weakened cells in an aged battery pack are no longer capable of meeting the high power requirements needed for the proper operation of your pruning saw, and therefore pose a safety risk.
5. Do not throw battery pack into an open fire as this poses a risk of explosion.
6. Do not ignite the battery pack or expose it to fire.
7. Do not exhaustively discharge the battery. Exhaustive discharge will damage the battery cells. The most common cause of exhaustive discharge is lengthy storage or non-use of partially discharged batteries. Stop working as soon as the performance of the battery falls noticeably or the electronic protection system triggers. Place the battery pack in storage only after they have been fully charged.
8. Protect the battery and the tool from overloads. Overloads will quickly result in overheating and cell damage inside the battery housing even if this overheating is not apparent externally.
9. Avoid damage and shocks. Immediately replace batteries that have been dropped from a height of more than one meter or those that have been exposed to violent shocks, even if the housing of the battery pack appears to be undamaged. The battery cells inside the battery may have suffered serious damage. In such instances, please read the waste disposal information for proper battery disposal.
10. If the battery pack suffers overloading and overheating, the integrated protective cutoff will switch off the equipment for safety reasons.
    
    Do not press the ON/OFF switch any more if the protective cut-off has been activated. This may damage to the battery packs.
11. Use only original battery packs. The use of other batteries poses a fire risk and may result in injuries or an explosion.

1. Remove the battery and adjust the chain tension.
2. Insert the battery and switch on the pruning saw and leave the motor running idle for approx. 5 minutes.
3. Remove the battery and check the chain tension again. If necessary, re-tighten the chain.
4. Afterwards make only easy cuts for approx. 30 minutes. Always ensure sufficient lubrication of the saw chain! Only use the pruning saw for heavier cuts and greater cutting depths after the break-in period.

Adjusting the Chain Tension

Use protective gloves when handling the bar and chain.

1. Make sure the pruning saw is shut off and the battery is removed. Loosen the sprocket/chain end cover a little by turning the end cover knob counterclockwise (Fig. 3).
   
2. Use the equipped hex key wrench to turn the chain adjusting screw clockwise to tighten, turn it counterclockwise to loosen. A cold chain will be correctly tensioned when there is no slack on the underside of the guide bar; the chain is snug, but it can be turned by hand without binding (Fig. 4).
   
   NOTE: When not in use, the hex key wrench can be stored in the hex key wrench slot located on the bottom of the pruning saw (Fig. 5).
   
3. Retighten the end cover knob. Using a screwdriver, run the chain along the guide bar to check that it moves smoothly.

Chain Lubricant

Only use a good quality bar and chain oil designed specifically for use with chain saws to ensure optimal lubrication of the cutting parts. Do not use oil containing impurities.

The chain lubricating oil is bio-degradable. The use of mineral oil or engine oil can have a serious impact on the environment. It is essential that you use good quality oil to lubricate the cutting parts effectively. Used or poor quality oil does not guarantee good lubrication and reduces the lifespan of the chain and bar.

Before lubricate the pruning saw, clean the guide bar and saw chain with a soft brush. Then drop the oil between the chain and the bar. Insert the battery and switch on the pruning saw. The oil will be evenly distributed over the chain. For optimal cutting result, lubricate the saw every 30 minutes during operation. When storing the unit for a long period of time (3 months or longer), be sure the chain is lightly lubricated; this will prevent rust on the chain and bar sprocket (Fig. 6).

Operation

Starting and Stopping

Starting, stopping, and restarting an electric motor repeatedly within a few seconds can generate a great deal of heat and damage the motor. To protect the life of your cordless pruning saw, always wait at least five seconds after stopping before restarting the saw.

Be sure that the chain is not in contact with any object when you start the motor.

Keep hands away from chain. Keep hand on handle. Do not overreach. A good, firm grip on the tool will help you maintain control. Maintain a firm grip by place your hand on the handle with thumb and fingers encircling the grip. A firm grip combined with proper positioning of the saw will help you maintain control of the saw. Do not let go of the saw while it is in operation.

Do not operate the cordless pruning saw in a tree, on a ladder, or on a scaffold. Using the tool under such circumstances is extremely dangerous.

The chain will continue to run for several seconds after turning off the tool.

Do not use the pruning saw under wet conditions. Use extreme caution when cutting small brush, saplings, or limbs under tension because slender and tense material may catch the saw and be whipped toward you, pull you off balance, or spring back.

Do not use the saw to cut vines and/or small underbrush.

Do not let familiarity with this type of tool prevent you from taking all necessary precautions. Remember that a careless fraction of a second is sufficient to inflict serious injury.

Do not cut branches near electrical wires.

Failure to lubricate the chain will cause damage to the bar and chain. Use only a good quality bar and chain oil designed specifically for use with chain saws.

1. Prior to each cutting session, run through the daily checklist.
2. Insert the battery in the battery compartment. Push to make sure it is locked in place (Fig. 7).
   
3. To turn the tool on, hold the pruning saw firmly on the handle grip. Press the safety lock button, and squeeze the ON/Off switch. When the pruning saw is running, you can release the safety lock button (Fig. 8).
   
4. To turn the tool off, simply release the On/Off switch.
   NOTE: Do not squeeze the On/Off switch until you are ready to make a cut.

Operating Tips

For your safety and that of others:

1. Do not use the machine without reading the instructions carefully. Become acquainted with the controls and the proper use of the machine. Learn how to stop the machine quickly.
2. Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people or their property.
3. Always wear suitable clothing when using the machine. Wear anti-vibration gloves and other personal protective equipment.
   All the above-mentioned precautions do not, however, guarantee the prevention of certain risks – i.e. Raynaud's phenomenon or Carpal tunnel syndrome. For operators who use this machine for prolonged periods, it is therefore recommended to have periodic checkups on their hands and fingers. If any of the above mentioned symptoms should appear, please contact a physician immediately.
4. Work only in daylight or good artificial light.
5. Take utmost care when working near metal fences.
6. Take care not to hit the bar hard against foreign objects or flying debris caused by the movement of the chain.
7. Never reach over the riving knife or under the base plate. There is a risk of injury!
8. Do not start the saw if the saw chain is in contact with any object, is in the workpiece or may hit an object. This can lead to serious injuries.
9. Clamp loose workpieces before cutting them. Remove foreign objects such as nails, screws, etc.
10. When cutting a branch that is under tension, be alert for spring back. When the tension in the wood fibers is released, the spring-loaded limb may strike the operator and/or throw the saw out of control.
11. Use extreme caution when cutting brush and saplings. The slender material may catch the saw chain and be whipped toward you or pull you off balance.
12. When the saw chain is running, place the base plate on the surface of the workpiece and let the saw cut on its own. Apply only light pressure to the saw.
    NOTE: The base plate helps to stabilize the saw and even the material that being cut. It can also reduce the vibration of the saw significantly. The base plate also acts like the fulcrum for deep cuts because it raises the back end of the saw. Using the base plate like a pivot point allows you to go deep in the material with precise control.
13. Stop the motor and remove the battery from the compartment:
    • Whenever you leave the machine unattended;
    • Before cleaning, checking or servicing the machine;
    • After striking a foreign object. Inspect the machine for any damage and make repairs before restarting it again;
    • If the machine begins to vibrate abnormally, immediately look for the cause of the vibrations and have the machine inspected at an authorized Snow Joe^® + Sun Joe^® dealer or call the Snow Joe^® + Sun Joe^® customer service center at 1-866-SNOWJOE (1-866-766-9563) for assistance;
    • When the machine is not in use.

Always remember that an incorrectly used pruning saw may disturb others and have a serious impact on the environment.

To respect people and the environment:

• Avoid using the machine in environments or at times of the day when it may disturb others.
• Scrupulously comply with local regulations and provisions for the disposal of waste materials after sawing.
• Scrupulously comply with local regulations and provisions for the disposal of oils, damaged parts or any elements which have a strong impact on the environment.
• A certain amount of chain lubricating oil is released into the environment when the machine is running, so only use biodegradable oils made specifically for this use.
• To avoid the risk of fire, do not leave the machine with the motor hot on leaves or dry grass.

It takes specific training to use this tool.

Checks During Work

• Checking the chain tension
  The chain tends to stretch gradually as you work, so you need to check its tension frequently.
  
  During the first period of use (or after replacing the chain), the chain tension must be checked more frequently due to settling of the chain.
  
  Never work with the chain loose, as it can be hazardous if the chain slips out of its guide.
  To adjust the chain tension, follow the instructions in "Adjust Chain Tension".
• Checking the oil delivery
  
  Never use the machine without lubrication! Make sure you lubricate the cutting area before and after using, and every 30 minutes during operation. For best results, use only a good quality bar and chain oil designed specifically for use with chain saws. Check the oil delivery as described below everytime after lubricate the chain.
  
  Make sure the bar and the chain are in place when you check the oil delivery.
  Start the motor and check if the chain oil is delivered as shown below (Fig. 9).
  

Basic Cutting Procedures

This unit is designed for trimming branches and limbs up to 4.5 in. (11.4 cm), not to exceed a max. cut of 4.5 in. (11.4 cm) in diameter depending on type of wood. Practice cutting a few small limbs using the following technique to get the "feel" of using the saw before you begin a major sawing operation.

• Grip the saw firmly on the handle grip.
• Squeeze the trigger switch and let the chain accelerate to full speed before entering the cut.
• Keep the unit running the entire time you are cutting, maintaining a steady speed.
• Let the chain do the work; exert only light downward pressure. If you force the cut, damage to the bar, chain, or unit can result.
• Do not put the pressure on the saw at the end of the cut.
• Always cut with both feet on solid ground to prevent falling.
• Do not cut above chest height since it is difficult to control kickback forces with a saw held high.

Maintenance

Please contact an authorized Snow Joe^® + Sun Joe^® dealer or call the Snow Joe^® + Sun Joe^® customer service center at 1-866-SNOWJOE (1-866-766-9563) for all maintenance operations not foreseen in this manual. Any operation performed in an unauthorized service center or by unqualified personnel will completely invalidate the warranty.

For your safety and that of others:

• Correct maintenance is essential to maintain the original efficiency and safety of the machine over time.
• Keep all nuts, bolts, and screws tight to be sure the equipment is in safe working condition.
• Never use the machine with worn or damaged parts. Damaged parts are to be replaced and never repaired.
• Only use original Snow Joe^® + Sun Joe^® replacement parts. Parts that are not of the same quality can seriously damage the equipment, compromise safety, and invalidate the warranty.

Always remove the battery before performing any adjustments, maintenance, or repairs to your cordless pruning saw.

• Use protective gloves when handling the bar and chain.
• Keep the bar encased in its sheath, except when working directly on the bar or the chain.
• Never dispose of oils or other polluting materials in unauthorized places.

Motor Cooling

To avoid overheating and damage to the motor, always keep the ventilation slots clean and free of sawdust and debris.

General Cleaning

It's recommended to clean the pruning saw immediately after each use for best performance. Use a cloth, a paintbrush or a brush to remove dust and wood splinters. Always keep the ventilation slots clean and free from obstructions. Clean the housing of the pruning saw regularly with a damp cloth and somewhat soft soap. Do not use any cleaning or solvent materials. Make sure that no water or any other liquid can get inside the cordless power tool.

Clean the sprocket area with a brush or compressed air (Fig. 10).

Replacing the Guide Bar and Chain

NOTE: When replacing the guide bar and chain, use only identical replacement parts. Make sure the battery is not inserted in the compartment before proceeding with operation.

Always wear heavy-duty gloves when handling the bar and chain. Mount the bar and chain very carefully so as not to impair the safety and efficiency of the machine. If in doubt, contact an authorized Snow Joe^® + Sun Joe^® dealer or call the Snow Joe^® + Sun Joe^® customer service center at 1-866-SNOWJOE (1-866-766-9563).

The operation should be completed on a flat and stable surface, with adequate space for moving the machine and its components.

Never start the motor before installing the guide bar, chain, and sprocket cover. Without all these parts in place, the clutch can fly off or explode, exposing the user to potentially serious injuries.

When you first purchase your pruning saw, the chain and bar will come pre-assembled on the saw. Should you need to replace the chain in the future, follow the steps below.

1. Screw the chain/sprocket end cover knob counterclockwise to release chain/sprocket end cover (Fig. 11).
   
2. Remove the cutting bar and chain from the mounting surface (Fig. 12).
   
3. Remove the old chain from the bar.
4. Lay out the new saw chain in a loop and straighten any kinks. THE SHARP SIDE OF THE TEETH MUST FACE AWAY FROM YOU IN THE DIRECTION OF THE CHAIN ROTATION INDICATED ON THE GUIDE BAR . If the teeth face backwards, turn the loop over (Fig. 13).
   
5. Starting at the tip, mount the chain drive links into the bar groove, leaving a loop at the back of the bar. The chain will loosely fit until it is placed on the sprocket (Fig. 14).
   
   NOTE: Make certain of the direction of the chain. If the chain is mounted backwards, the saw will vibrate abnormally and will not cut.
6. Hold the chain in position on the bar and place the loop around the sprocket. Fit the bar against the mounting surface so that the extruded piece on the mounting surface is in the long slot of the bar and the adjusting pin is in the chain tension pin hole (Fig. 15).
   
7. While keeping the bar and chain against the mounting surface, adjust the chain tension as needed by adjusting the chain tensioner screw with the supplied hex key wrench. Turn the chain tensioner screw clockwise to tightening the chain, or counter-clockwise to loosen the chain (Fig. 4).
8. Replace the chain/sprocket end cover by inserting the tab located on the bottom first into the slot and position the cover over the bar end. Tighten the end cover knob; leave the bar loose enough to move slightly for tension adjustment (Fig. 16).
   

Chain Tension

Check the chain tension before using the saw when the chain is cold. The correct tension of a cold chain is when there is no slack on the underside of the guide bar; the chain is snug, but you can rotate it by hand without binding.

During normal saw operation, the temperature of the chain will increase. The drive links of a correctly tensioned warm chain will hang approximately 0.050 in. (1.25 mm) out of the bar groove (Fig. 17). Be aware that a chain tensioned while warm, may be too tight upon cooling. Check the "cold tension" before next use. The chain must be re-tensioned whenever the flats on the drive links hang out of the bar groove (Fig. 17).

Chain Sharpening

To ensure that the saw works safely and efficiently, it is essential that the cutting components are well-sharpened. It is highly recommended to replace the chain once it loses its ability to cut cleanly and safely. It is possible, however, to sharpen the existing chain if the sharpening is carefully performed. Any work on the chain and bar requires specific experience and special tools. For safety purposes, we recommend you contact an authorized Snow Joe^® + Sun Joe^® dealer or call the Snow Joe^® + Sun Joe^® customer service center at 1-866-SNOWJOE (1-866-766-9563).

Sharpening is necessary when:

• The sawdust looks like dust;
• Cutting becomes more difficult;
• The cut is not straight;
• Vibrations increase.

An authorized service center will sharpen the chain using the right tools to ensure minimum removal of material and even sharpness on all the cutting edges.

If you sharpen the chain by yourself, it's recommended to purchase Sun Joe^® 24V-CSSHRP-LTE chain saw sharpener, which can be powered by the same 24V iON+ battery with this cordless pruning saw. Visit sunjoe.com or call the Snow Joe^® + Sun Joe^® customer service center at 1-866-SNOWJOE (1-866-766-9563) to order.

Otherwise, use special round-section files with the right diameter depending on the type of chain (see "Chain Maintenance Table"). You need a certain amount of skill and experience to avoid damaging the cutting edges.

Sharpen the chain as follows (Fig. 18):

• Secure the bar firmly, with the chain mounted, in a suitable vise.
• Tighten the chain if it is loose.
• Mount the file in the guide and then insert it in the tooth at a constant angle from the cutting edge.
• Sharpen in a forward motion a few times and repeat this on all the cutting edges facing the same way (right or left).
• To move the chain forward, use a screwdriver.
• Turn the bar over in the vise and repeat on all the other cutting edges.
• Check that the depth limiter tooth does not stick out farther than the inspection tool and file any projecting parts with a flat file, rounding off the edges (Fig. 18).
• After sharpening, remove all traces of filing and dust and lubricate the chain in an oil bath. Replace the chain whenever:
  • The length of the cutting edges decreases to 5 mm or less;
  • There is too much play between the links and the rivets.

Guide Bar Maintenance

When the guide bar shows signs of wear, turn it over on the saw to distribute the wear for maximum bar life. Feathering or burring of the bar rails is a normal process of bar wear. You should smooth such faults with a file as soon as they occur.

Replace a bar with any of the following faults:

• wear inside the bar rails permitting the chain to lay over sideways
• bent guide bar
• cracked or broken rails
• spread rails

Turn the saw over, check the underside of the guide bar, and make sure that the lubrication holes and chain groove are free from impurities.

You can purchase replacement parts for your Sun Joe^® 24V-HCS-LTE cordless pruning saw by ordering online at sunjoe.com or, to order by phone, contact Snow Joe^® + Sun Joe^® customer service at 1-866-SNOWJOE (1-866-766-9563).

Chain Sprocket

Regularly check the condition of the sprocket and replace it when wear exceeds 0.5 mm (Fig. 19).

Do not mount a new chain with a worn sprocket or vice-versa.
