SAVE THESE INSTRUCTIONS

Double-Insulated Appliances
In a double-insulated appliance, two systems of insulation are provided instead of grounding. No grounding means that it is already provided on a double-insulated appliance. Servicing a double-insulated appliance requires extreme care and knowledge of the system, and should be performed only by qualified service personnel at an authorized Snow Joe ® Sun Joe ® dealer. Replacement parts for a double-insulated appliance must be identical to the parts they replace. A double-insulated appliance is marked with the words "Double Insulation" or "Double Insulated." The symbol (square within a square) may also be marked on the appliance.

DOUBLE-INSULATED: GROUNDING NOT REQUIRED. WHEN SERVICING, USE ONLY IDENTICAL REPLACEMENT PARTS.
This electric scarifier + dethatcher is double-insulated, eliminating the need for a separate grounding system. Use only identical replacement parts. Read the instructions before servicing double-insulated appliances. Use this electric scarifier + dethatcher only as described in this manual.

Electric Safety

1. Ground fault circuit interrupter (GFCI) protection should be provided on the circuit(s) or outlet(s) to be used for the dethatcher. Receptacles are available having built-in GFCI protection and may be used for this measure of safety.
2. To prevent electric shock, use only with an extension cord suitable for outdoor use, such as SW-A, SOW-A, STW-A, STOW-A, SJW-A, SJOW-A, SJTW-A, or SJTOW-A. Before use, check that the extension cord is in good condition. When using an extension cord, make sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.
   
   Electric shock may cause SEVERE INJURY or DEATH. Heed these warnings:
   • Do not allow any part of the electric scarifier + dethatcher to make contact with water while it is in operation. If the appliance becomes wet while turned off, wipe dry before starting.
   • Use only a UL-, CSA-, or ETL-rated extension cord for outdoor, all-weather use, such as the Snow Joe ® + Sun Joe ® SJTW-A 14-gauge 50-foot extension cord with lighted end (Model PJEXT50-B). Visit sunjoe.com to purchase this extension cord online or, to order by phone, call 1-866-SNOWJOE (1-866-766-9563).
   • Do not use an extension cord over 100 ft (30 m).
   • Do not touch the appliance or its plug with wet hands or while standing in water. Wearing rubber boots offers some protection.

     Wire Gauge (A.W.G.):	14	12

3. To reduce the risk of electric shock, this appliance has a polarized plug (i.e. one blade is wider than the other). Use this appliance only with a polarized, UL-listed (CSA certified in Canada) extension cord recommended for outdoor use. The appliance plug will fit into a polarized extension cord only one way. If the appliance plug does not fit fully into the extension cord, reverse the plug. If the plug still does not fit, obtain a correct polarized extension cord. A polarized extension cord will require the use of a polarized wall outlet. The extension cord plug will fit into the polarized wall outlet only one way. If the plug does not fit fully into the wall outlet, reverse the plug. If the plug still does not fit, contact a qualified electrician to install the proper wall outlet. Do not modify the appliance plug, extension cord receptacle or extension cord plug in any way.
4. To prevent the appliance cord from disconnecting from the extension cord during operation, make a knot with the two cords as shown in Table 1.

Intended Use

1. This scarifier + dethatcher is designated with a 13 amp motor. Depending on the fitted cutting device, this machine is either intended for scarifying and removing thatch from lawns or raking in domestic and hobby gardens.
2. When used as a scarifier, this machine works by scratching through and between the grass with specially adapted prongs that collect and remove any unwanted parts from the lawn while leaving the grass blades intact. At the same time the machine scarifies the ground resulting in a better aeration.
3. When used as a dethatcher the fine needles will scratch the surface of the lawn while simultaneously picking up light debris for better oxygen absorption, airing and drainage.
4. This machine is not to be used in wet weather conditions and may not be used to mow dry, wet or unusually high grass, e.g., pasture grass or for shredding leaves.
5. This machine is intended for private domestic use only, not for any commercial trade use. It must not be used for any purposes other than those described.

Operation

Cutting Depth Adjustment

The unit must be switched off and disconnected from the power supply before adjusting the tine settings. Adjust the depth according to the needs of your lawn. The most suitable depth depends on the kind of lawn and the actual height of the grass.

1. Pull the depth adjustment lever away from the wheel, then move it forward or backward to adjust the cutting depth (Fig. 8).
   
   
2. Adjust the lever to one out of the five stages. Read the adjusted depth from the scale.

   Setting	Depth	Application
   High	10 mm	For pushing behind with the machine; and removing thin thatch layers. Do not use for scarifying.
   Minimal	5 mm	For raking healthy lawn. Do not use for scarifying.
   Middle	0 mm	For transport, storage, scarifying and raking.
   Deep	-5 mm	For scarifying, not recommended for raking.
   Deep	-10 mm	For scarifying, do not use for raking.

Power Connection
Push a loop of the extension cord through the slot on the extension cord restraint holder from the opposite side of the restraint holder (Fig. 9). Insert the appliance cord into a proper outdoor extension cord (see Extension Cord Chart).

Starting + Stopping

Before switching on the lawn scarifier + dethatcher, make sure that it is not in contact with any foreign objects. Keep your feet and hands a safe distance away from the rotating tines and the ejector opening. Failure to comply with these warnings can result in severe personal injury.

1. To start, press and hold the safety lock button while pulling the switch lever toward you. Once the machine powers on, release the safety lock button and proceed with operation (Fig. 10).
   
   
2. To stop the lawn scarifier + dethatcher, release the switch lever.

The tine cylinder continues to run for a brief period after the unit has been switched off. Do not tilt or carry the unit while the motor is still running and do not touch the cylinder while it is still rotating. Failure to comply could result in severe personal injury.

Overload Protection
The overload protection will be activated in the following circumstances:

1. A build up of scarified material around the cutting device.
2. If the material scarified is larger than the motor capacity.
3. Where there is too much resistance against the cutting device.

When the circuit breaker has been activated switch off the product and disconnect from the power supply. Let the product cool down and eliminate the cause before using the product again.

General Operation

If the product strikes a foreign object stop the motor. Switch the product off, disconnect it from the power supply and let it cool down. Inspect the product thoroughly for damage. Have any damage repaired before restarting.

Extensive vibration of the product during operation is an indication of damage. The product should be promptly inspected and repaired.

• Check the machine, its power cord and plug as well as accessories for damage before each use. Do not use the machine if it is damaged or shows wear.
• Double check that accessories are properly fixed.
• Push the machine forward by its handle. Keep the handle dry to ensure safe support.
• Ensure that the air vents are always unobstructed and clear. Clean them if necessary with a soft brush. Blocked air vents may lead to overheating and damage the product.
• Switch the machine off immediately if you are disturbed while working by other people entering the working area. Always let the machine come to complete stop before putting it down.
• Do not overwork yourself. Take regular breaks to ensure you can concentrate on the work and have full control over the machine.
• Mow the lawn before working and fertilize afterwards.
• Make sure that the lawn is clear of stones, sticks, wire, or other objects that could damage the machine or its motor.
• Select the suitable cutting depth for the actual grass height.
• Do not work with this machine on a wet lawn because it tends to stick to the underbody of the machine, preventing the proper discharge of collected material, and it could also cause you to slip and fall.
• Slowly push the machine forward. Move the machine at appropriate speed. Do not move it too fast to prevent the discharge from getting blocked and engine from useless overloading.

• Work in slight overlapping rows. The most effective pattern for scarifying/raking lawns is straight lines along one of the sides. This will keep the rows even and ensures that all the lawn is scarified/raked without missing any spots (Fig. 11).
  
  
• Circle around flower beds. When reaching a flower bed in the middle of the lawn, make a row or two around the circumference of the bed.
• Pay special attention when changing direction.

Scarifying
Consider the weather when scarifying. Scarify the lawn with an increased depth setting during spring time between April and May as the lawn is better able to recover during this season. During a wet summer scarify again in late summer with a decreased depth setting. Do not scarify during periods of hot weather condition. During a dry rainless summer do not scarify a second time in autumn.

Raking
In order for a healthy lawn to develop in the spring, it is necessary for greater amounts of air to penetrate the area around the roots of the grass. We recommend aerating the lawn every 4 – 6 weeks depending on the state of your lawn.

Maintenance

Before carrying out any repairs or servicing work, you must ensure that the machine has been disconnected from the power supply. Repairs and maintenance work other than described within this instruction manual may be performed only by qualified specialist!

Service + Storage
To ensure long and reliable service, carry out the following maintenance regularly. Servicing and cleaning work on the machine and the removal of the guards may only be carried out after the motor has been switched off and the plug disconnected from the power supply.

• Keep all nuts, bolts and screws tight to be sure the product is in a safe working condition.
• Allow the product to cool before storing in any enclosure.
• Check the thatch collection bag frequently for wear or deterioration.
• Examine the product regularly and replace worn or damaged parts for safety.
• Check that covers and guards are undamaged and correctly fitted. Carry out necessary maintenance or repairs before using the machine.
• If the cutting device should happen to fail despite the care taken in manufacturing and testing, repair should be carried out by an authorized repair facility.

• Ensure that all the fastening elements (screws, nuts, etc.) are tight at all times so that you can safely work with the machine.
• Check the machine frequently for signs of wear. Replace worn or damaged parts.
• Store your machine in a dry place. To ensure a long service life all screws and bolts should be cleaned and then oiled.
• Clean the machine with a brush or cloth. Do not use any solvents or water to remove dirt.
• The component that is subject to most wear is the cutting device. You should therefore check the condition of the cutting device and its mounting at regular intervals.
  • If the cutting device is worn or blunt it must be replaced immediately.
  • If the machine starts to suffer from excessive vibrations, this means that the cutting device has not been balanced correctly or has suffered deformation due to impacts. In this case it must be repaired or replaced.

Replacing/Changing Cutting Device

Always switch the machine off, disconnect it from power supply and let it cool down before changing/ replacing the cutting device.

Cutting devices are very sharp and become hot during use. Handle them carefully.

Wear safety gloves when handling cutting devices in order to avoid injuries like burns and cuts.
