EGO STA1500 - String Trimmer Manual

SAFETY SYMBOLS

The purpose of safety symbols is to attract your attention to possible dangers. The safety symbols and the explanations with them deserve your careful attention and understanding. The symbol warnings do not, by themselves, eliminate any danger. The instructions and warnings they give are no substitutes for proper accident prevention measures.

Be sure to read and understand all safety instructions in this Operator's Manual, including all safety alert symbols such as "DANGER," "WARNING," and "CAUTION" before using this tool. Failure to following all instructions listed below may result in electric shock, fire, and/or serious personal injury.

SYMBOL MEANING
SAFETY ALERT SYMBOL: Indicates DANGER, WARNING, OR CAUTION.

IMPORTANT SAFETY INSTRUCTIONS

Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains chemicals known to the state of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints
• Crystalline silica from bricks and cement and other masonry products, and
• Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

When using electric trimmers, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and personal injury, including the following:

READ ALL INSTRUCTIONS

Do not rely on the tool's insulation against electric shock. To reduce the risk of electrocution, never operate the tool in the vicinity of any wires or cables which may carry electric current.

Wear appropriate personal hearing protection during use. Under some conditions and durations of use, noise from this product may contribute to hearing loss.

• Keep Children Away - All visitors should be kept at least 100 feet away from work area.
• Avoid Dangerous Environments – Don't use appliances on damp or wet slope.
• Dress Properly - Do not wear loose clothing or jewelry. They can be caught in moving parts. Use of rubber gloves and substantial footwear is recommended when working outdoors. Wear protective hair covering to contain long hair.
• Use Safety Glasses - Always use face or dust mask if operation is dusty.
• Use the Right Tool - Do not use the tool for any job except that for which it is intended.
• Don't Force the Trimmer - It will do the job better and with less likelihood of a risk of injury at the rate for which it was designed.
• Don't Overreach - Keep proper footing and balance at all times.
• Stay Alert - Watch what you are doing. Use common sense. Do not operate the trimmer when you are tired.
• Do not operate the trimmer while under the influence of alcohol or drugs.
• Keep guards in place and in working order.

To reduce the risk of injury to persons, do not operate without guards in place.

• Keep hands and feet away from the cutting area.
• Store Trimmer Indoors - When not in use the trimmer should be stored indoors in a dry and high or locked-up place with the battery pack removed- out of reach of children.
• Maintain Trimmer With Care - Keep the cutting attachment clean for best performance and to reduce the risk of injury. Follow the instructions for changing accessories. Keep the handles dry, clean, and free from oil and grease.
• Check Damaged Parts - Before further use of the trimmer, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other condition that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service center unless indicated elsewhere in this manual.
• Clear the area to be cut before each use. Remove all objects such as rocks, broken glass, nails, wire, or string that can be thrown or become entangled in the cutting attachment. Make sure that other persons and pets are at least 100 ft. (30.5m) away.
• Always hold the trimmer firmly, with both hands on the handles, while operating. Wrap your fingers and thumbs around the handles.
• Avoid Accidentally Starting - Don't carry the trimmer with your finger on the trigger.
• Do not operate the trimmer in gaseous or explosive atmospheres. Motors in these appliances normally spark, and the sparks might ignite fumes.
• Damage to Trimmer - If you strike a foreign object with the trimmer or it becomes entangled, stop the tool immediately, check for damage and have any damage repaired before further operation is attempted. Do not operate with a broken guard or spool.
• If the equipment should start to vibrate abnormally, stop the motor and check immediately for the cause. Vibration is generally a warning of trouble. A loose head may vibrate, crack, break or come off the trimmer, which may result in serious or fatal injury. Make sure that the cutting attachment is properly fixed in position. If the head loosens after fixing it in position, replace it immediately. Never use a trimmer with a loose cutting attachment.
• Replace a cracked, damaged or worn-out cutting head immediately, even if damage is limited to superficial cracks. Such attachments may shatter at high speed and cause serious or fatal injury.
• Check the cutting attachment at regular short intervals during operation, or immediately if there is a noticeable change in cutting behavior.
• When replacing the cutting line, use no more than 2.4mm nylon line; using heavier lines than recommended by the manufacturer increases the load on the motor and reduces its operating speed. This results in overheating and damage to the trimmer.
• To reduce the risk of serious injury, never use wire or metal-reinforced line or other material in place of the nylon cutting lines. Pieces of wire could break off and be thrown at high speed toward the operator or bystanders.
• To reduce the risk of injury from loss of control, never work on a ladder or on any other insecure support. Never hold the cutting attachment above waist height.
• Do not charge the battery pack in rain, or in wet locations.
• Use only with the battery packs and chargers listed below:

BATTERY PACK	CHARGER
BA1120, BA1400, BA2240, BA2800, BA4200	CH2100 CH5500

• Use Only With The 56V Lithium-Ion Power Head PH1400.
• Do not dispose of the battery in a fire. The cells may explode. Check with local codes for possible special disposal instructions.
• Do not open or mutilate the battery. Released electrolyte is corrosive and may cause damage to the eyes or skin. It may be toxic if swallowed.
• 
  Exercise care in handling batteries in order not to short the battery with conducting materials such as rings, bracelets, and keys. The battery or conductor may overheat and cause burns.
• Replacement Parts - When servicing, use only identical EGO replacement parts. Use of any other accessory or attachment may increase the risk of injury.
• Battery tools do not have to be plugged into an electrical outlet; therefore, they are always in operating condition. Be aware of possible hazards even when the tool is not operating. Take care when performing maintenance or service.
• Remove or disconnect battery pack before servicing, cleaning or removing material from the trimmer.
• Do not wash with a hose; avoid getting water in motor and electrical connections.
• If situations occur that are not covered in this manual, use care and good judgment. Contact the EGO Customer Service Center for assistance.

Save these instructions. Refer to them frequently and use them to instruct others who may use this tool. If you lend this tool to someone else, also lend these instructions to them to prevent misuse of the product and possible injury.

USING THE DEVICE

To avoid serious personal injury, wear goggles or safety glasses at all times when operating this unit. Wear a face mask or dust mask in dusty locations.

Clear the area to be cut before each use. Remove all objects, such as rocks, broken glass, nails, wire, or string that can be thrown or become entangled in the cutting attachment. Clear the area of children, bystanders, and pets. At a minimum, keep all children, bystanders and pets at least 100 feet (30.5m) away; there still may be risk to bystanders from thrown objects. Bystanders should be encouraged to wear eye protection. If you are approached, stop the motor and cutting attachment immediately.

To prevent serious personal injury, remove the battery pack from the tool before servicing, cleaning, changing attachments or removing material from the unit.

Before each use check for damaged/worn parts
Check the trimmer head, guard and front-assist handle and replace any parts that are cracked, warped, bent, or damaged in any away.
The line-cutting blade on the edge of the guard can dull over time. It is recommended that you periodically sharpen it with a file or replace it with a new blade.

Always wear gloves when mounting or replacing the guard or when sharpening or replacing the blade. Note the location of the blade on the guard and protect your hand from injury.

TO START/STOP THE TOOL

See "STARTING/STOPPING THE POWER HEAD" section in the power head PH1400 operator's manual.

Tips for best trimming results (Fig. 6)

• The correct angle for the cutting attachment is parallel to the ground.
• Do not force the trimmer. Allow the very tip of the line to do the cutting (especially along walls). Cutting with more than the tip will reduce cutting efficiency and may overload the motor.
• The cutting height is determined by the distance of the cutting line from the lawn surface.
• Grass over 8 inches (200 mm) should be cut by working from top to the bottom in small increments to avoid premature line wear or motor drag.
• Slowly move the trimmer into and out of the area being cut, maintaining the cutting head position at the desired cutting height. This movement can be either a forward-backward motion or a side-to-side motion. Cutting shorter lengths produces best results.
• Trim only when grass and weeds are dry.
• Wire and picket fences can cause extra string wear or breakage. Stone and brick walls, curbs, and wood may wear strings rapidly.
• Avoid trees and shrubs. Tree bark, wood moldings, siding, and fence posts can easily be damaged by the strings.

ADJUSTING CUTTING LINE LENGTH

The trimmer head allows the operator to release more cutting line without stopping the motor. As line becomes frayed or worn, additional line can be released by lightly tapping the trimmer head on the ground while operating the trimmer (Fig. 7).

Do not remove or alter the line-cutting blade assembly. Excessive line length will cause the motor to overheat and may result in serious personal injury.

For best results, tap the trimmer head on bare ground or hard soil. If line release is attempted in tall grass, the motor may overheat. Always keep the trimming line fully extended. Line release becomes more difficult as the cutting line becomes shorter.

LOAD NEW CUTTING LINE

NOTICE: Always use the recommended nylon cutting line with diameter not greater than 0.095in. (2.4mm). Using line other than that specified may cause the string trimmer to overheat or become damaged.

Never use metal-reinforced line, wire, or rope, etc. These can break off and become dangerous projectiles.

To prevent serious personal injury, remove the battery pack from the power head before servicing, cleaning, changing attachments or removing material from the unit.

1. Remove the battery pack.
2. Remove the remaining cutting line, if necessary. Simply pull it out by hand.
3. Rotate the spool retainer in the direction indicated by the arrow, as necessary, to align the LOAD line on the spool retainer with the eyelets in the spool base (Fig. 8).
   
4. Cut one piece of cutting line 16ft. (5m) long. Insert the line into the mounting hole located inside the eyelet. Push the line until the end of the line comes out of the other side of the spool base. Pull the line from the other side until equal amounts of line appear on both sides of the spool (Fig. 9).
   
5. Press, while rotating the spool retainer in the direction indicated by the arrow, to wind the cutting line onto the spool until approximately 5.5in. (14cm) of line is showing on each side (Fig. 10).
   
6. Push the spool retainer down while pulling on the lines to manually advance the line and to check for proper assembly of the trimmer head.

When the cutting line breaks from the line outlet or the cutting line is not released when the trimmer head is tapped, follow the steps below:

1. Remove the battery pack.
2. Press the release tabs on the spool retainer and remove the spool retainer by pulling it straight out (Fig. 11 & 12).
   
3. Remove the cutting line from the spool retainer.
4. With one hand holding the spool base, use the other hand to grasp the spool retainer and align the tabs on the spool retainer with the holes in the spool base (Fig. 13); use your palm to press and rotate the spool retainer left and right until the tabs lock with the spool base (Fig. 14).
   
5. Following the instructions in "LOAD NEW CUTTING LINE" to reload the cutting line.

MAINTENANCE

When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage. To ensure safety and reliability, all repairs should be performed by a qualified service technician.

Battery tools do not have to be plugged into an electrical outlet; therefore, they are always in operating condition. To prevent serious personal injury, take extra precautions and care when performing maintenance, service or for changing the cutting attachment or other attachments.
