IMPORTANT SAFETY INSTRUCTIONS

WARNING! 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:

DANGER! 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

CAUTION! 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 inmoving 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.
  • 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, brokenglass, 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)
  • Alway. 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.
  • If situations occur that are not covered in this manual, use care and good judgment. Contact the EGO Customer Service Center for assistance.
  • Do not charge the battery pack in rain, or in wet locations.
  • Use only with the battery packs and chargers listed below:

Clean the trimmer after each use
See the Maintenance section for cleaning instructions.

WARNING: Never use water to clean your trimmer. Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents. Use clean cloths to remove dirt, dust, oil, grease, etc.

Tips for best trimming results (Fig. 15
trimmer Rotation

  • 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 (200mm) should be cut by working progressively 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. 16).
Adjusting
WARNING: 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.

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

WARNING: Always use the recommended nylon cutting line with diameter no more than 0.095 in. (2.4mm). Using line other than that specified may cause the string trimmer to overheat or become damaged.

The string trimmer is equipped with an advanced POWERLOADTM system. The cutting line can be wound onto the spool simply by pressing a single button. Loading a full spool can usually be completed in 12 seconds. Avoid repeated operation of the winding system in rapid succession to reduce the possibility of motor damage.

  1. Remove the battery pack from the trimmer.

  2. Cut one piece of cutting line 13 ft. (4m) long

  3. Insert the line into the eyelet (Fig.17) and push the line until the end of the line comes out of the opposite eyelet
    Inserting
    NOTICE: It is not necessary to align the eyelets in order to insert the cutting line. If the line cannot be inserted into the eyelet, mount the battery pack onto the trimmer, then press the line-loading button briefly to release the lower cover.
