ASSEMBLY

UNFOLDING THE SHAFT

In order to avoid pinching your hands or fingers, do not hold the shaft at the joint.

Do not attempt to start the trimmer until the shaft has been locked.
Unfold the shaft gently, ensuring the cable inside the shaft and lock it with the bolt by the supplied wrench.

MOUNTING THE GUARD

Always wear gloves when mounting or replacing the guard. Be careful of the blade on the guard and protect your hands from being injured by the blade.
Position your trimmer so that the trimmer head faces up (Fig. C1). Align the guard mounting holes with the assembly holes and then lock the guard on the shaft base with the two screws (Fig. C2).

NOTICE: Make sure the guard is fixed according to Fig. C1 & C2, any reverse fixing will cause great danger!

MOUNTING AND ADJUSTING THE FRONT HANDLE

1. Loosen and remove the quick-release lever and wing nut from the front handle.

2. Push the front handle onto the shaft within the mounting zone between the height locking collar and hinge.
   
3. Insert the clamping block into the handle slot.
   
4. Mount the quick-release lever and pretighten the wing nut. Make sure that the front handle is positioned upwards and points toward the top of the rear handle.
   
5. Pull the quick-release lever up to move/rotate the front handle to a comfortable operating position, and then lock the quick-release lever.
   

NOTICE: The front handle should be positioned on the shaft only within the mounting zone.

The tool cannot be used without the front handle securely fixed.

ADJUSTING THE TRIMMER HEIGHT

If the length of the shaft is not suitable for operation, you can adjust the length of the shaft through the height locking collar.

1. Remove the battery pack from the trimmer.
2. To adjust the trimmer height (i.e., shaft length), open the height locking collar, and then slide the shaft up or down to desired height, securing it in place by depressing the height locking collar.
   

   E-1	Height locking collar

NOTICE: The front handle may need to be repositioned after the trimmer height is changed.

ATTACHING SHOULDER STRAP

For safe and better operation, put the strap over one of your shoulders and across your back.

1. Loosen screw knob and hex nut from the shoulder strap loop.
   

   F1-1	Screw knob
   F1-2	Hex nut
   F1-3	Should strap loop

2. Place the shoulder strap loop at a comfortable operating position within the installation zone, and then fix it by tightening the screw knob and hex nut.
3. Depress the shoulder strap carabiner to open it and attach the shoulder strap to the hole on the strap loop.
   
4. Adjust the shoulder strap length and placement to a comfortable operating position.

OPERATION

Always wear safety goggles or safety glasses with side shield, along with hearing protection. Failure to do so could result in objects being thrown into your eyes and other possible serious injuries.
Trimming: grass and weeds from around porches, fences, and decks.
Cutting: grass that is difficult to reach using a normal mower.

ATTACHING/DETACHING THE BATTERY PACK

Use only with EGO's battery packs and chargers listed in Fig. A2

Fully charge before first use.

To Attach
Align the battery ribs with the mounting slots and press the battery pack down until you hear a "click".

To Detach
Depress the battery-release button and pull the battery pack out.

HOLDING THE LINE TRIMMER

For safe and better operation, put on the shoulder strap across the shoulder. Adjust the shoulder strap length and placement to a comfortable operating position – hold the trimmer with both hands: one hand on the rear handle and the other hand on the front handle.

NOTICE: The trimmer head is parallel to the ground at a proper cutting distance without the operator bending over.

When an emergency occurs, take the shoulder strap off from your shoulder immediately, no matter what way the strap is on.

STARTING/STOPPING THE LINE TRIMMER

To Start
Move the locking tongue forward and then press the variable speed trigger.
The trigger is stepless speed adjusting. The more you pull up the trigger, the higher speed it is.

To Stop
Release the variable speed trigger.

SPEED ADJUSTMENT FUNCTION

The line trimmer has two speed setting. Press the 2-speed switch to change cutting speed between the low and high.
The speed indicator will display the active speed status: one light for low speed and two lights for high speed. The low speed range provides better control of the trimmer and longer operating time per charge.

USING THE LINE TRIMMER

Clear the area to be cut before each use. Remove all objects, such as rocks, broken glass, nails, wire, or lien 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 15 m 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.
Before each use check for damaged/worn parts
Check the trimmer head, guard, shoulder strap, shoulder strap loop, and front handle. Replace any parts that are cracked, warped, bent, or damaged in any way.
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 line-cutting blade. Note the location of the blade on the guard and protect your hands from injury.
After each use, clean the trimmer.

ADJUSTING THE CUTTING LINE LENGTH

The Line-IQ feeding trimmer head is equipped with advanced technology.
If either end of the cutting line wears less than 18 cm during trimming, the trimmer head will release cutting line automatically, and the extra part of the cutting line will be cut off by the line-cutting blade.

NOTICE: No need to tap the trimmer head to release the cutting line. If you feel a slight tremor of the trimmer head when trimming the grass, it is the cutting line being automatically released.

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.

LINE REPLACEMENT

NOTICE: Always use the recommended nylon cutting line with a diameter of 2.4 mm.
Using line other than that specified may cause the tool to overheat or become damaged.

Never use metal-reinforced line, wire, or rope, etc. These can break off and become dangerous projectiles.
The line trimmer is equipped with an advanced POWERLOAD^TM 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.
2. Cut one piece of cutting line 4 m long.
3. Insert the line into the eyelet and push the line until the end of the line comes out of the opposite eyelet.
   

   L1-1	Cutting line
   L1-2	Eyelet

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 POWERLOAD button briefly to reset the winding mechanism.

4. Remove the battery pack if it has been mounted onto the trimmer in step 3.
5. Pull the line from the other side until equal lengths of the line appear on both sides of the trimmer head.
   
6. Install the battery pack onto the line trimmer.
7. Press and hold the POWERLOAD button to start the line-winding motor. The line will be wound into the trimmer head continuously.
8. Watch the remaining line length carefully. Prepare to release the button as soon as approximately 22 cm of line are left on each side. Briefly press the line loading button to adjust the length until 18 cm of the line is showing on each side.
   

NOTICE: In case the line is pulled into the trimmer head by accident, open the head and pull the cutting line out from the spool. Follow the section "RELOADING THE CUTTING LINE" in this manual to reload the line.

RELOADING THE CUTTING LINE

NOTICE: When the cutting line gets stuck in the trimmer head, you will need to remove the remaining cutting line from the trimmer head and follow the steps below to reload the 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.

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

Obstructions in the vents will prevent the air from flowing into the motor housing and result in overheating or damaged of the motor.

CLEANING THE UNIT

• Clean the unit using a damp cloth with a mild detergent. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.
• Do not use any strong detergents on the plastic housing or the handle. They can be damaged by certain aromatic oils, such as pine and lemon, and by solvents such as kerosene. Moisture can also cause a shock hazard. Wipe off any moisture with a soft, dry cloth.
• Use a small brush or the air discharge of a small vacuum cleaner brush to clean the air vents on the rear housing.
• Keep the air vents free of obstructions.

SHARPENING THE LINE-CUTTING BLADE

Always protect your hands by wearing heavy gloves when performing any maintenance on the line-cutting blade.

1. Loosen the two screws and remove the line-cutting blade from the guard.
