TO INSTALL BATTERY PACK

See Figure 5.

■ Place the battery pack in the trimmer. Align raised ribs on battery pack with grooves in the trimmer’s battery port.
■ Make sure the latch on the back of the battery pack clicks into place and that battery pack is fully seated and secure in the trimmer before beginning operation.

TO REMOVE BATTERY PACK

See Figure 5.

■ Release the switch trigger and lock-out trigger to stop the trimmer.
■ Press and hold the battery latch button on the back of the battery pack.
■ While holding the battery latch place one hand the the trimmer handle and remove battery pack.

STARTING / STOPPING THE TRIMMER

See Figure 6.

■ Ensure a fully charged battery is installed into the string trimmer.
■ To start the string trimmer, press and hold the lock-out button (1) and squeeze the switch trigger (2).
■ To stop the string trimmer, release switch trigger to stop.

OPERATING THE TRIMMER

Follow these tips when using the trimmer:

■ Hold the trimmer with your right hand on the rear handle and your left hand on the front handle.
■ Keep a firm grip with both hands while in operation.
■ Trimmer should be held at a comfortable position with the rear handle about hip height.
■ Cut tall grass from the top down. This will prevent grass from wrapping around the shaft housing and string head which may cause damage from overheating.

If grass becomes wrapped around the string head:

■ Remove the battery pack from the trimmer.
■ Remove the grass.

 WARNING
Contact with the trimmer cutting head while operating can result in serious personal injury.

ADVANCING LINE

NOTE: The trimmer is equipped with an auto-feed head. Bumping the head to try to advance the line will damage the trimmer and void the warranty.

■ With the trimmer running, release the switch trigger.
■ Wait two seconds, and press the switch trigger.

NOTE: The line will extend approximately 1/4 in. with each stop and start of the switch trigger until the line reaches the length of the grass deflector cut-off blade.

■ Resume trimming.

ADVANCING THE LINE MANUALLY

See Figure 7.

■ Remove the battery pack.
■ Push the black button located on the cutting head while pulling on cutting line to manually advance the cutting line.
■ After extending new cutter line, always return the machine to its normal operating position before switching on.

CUTTING TIPS

See Figure 8.

■ Keep the trimmer tilted toward the area being cut; this is the best cutting area.
■ The trimmer will cut better when moved from left to right across the area to be cut; it is less effective when moved from right to left.
■ Use the tip of the cutting line to do the cutting; do not force cutting head into uncut grass.
■ Wire and picket fences cause extra cutting line wear, even breakage. Stone and brick walls, curbs, and wood may wear cutting line rapidly.
■ Avoid trees and shrubs. Tree bark, wood moldings, siding, and fence posts can easily be damaged by the cutting line.

LINE CUT-OFF BLADE

See Figure 9.

This trimmer is equipped with a line cut-off blade on the grass deflector. For best cutting, advance line until it is trimmed to length by the line cut-off blade. Advance line whenever you hear the engine running faster than normal, or when trimming efficiency diminishes. This will maintain best performance and keep line long enough to advance properly.

 WARNING
When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage.

 WARNING
To avoid serious personal injury, always remove the battery pack from the tool when cleaning or performing any maintenance.

GENERAL MAINTENANCE

Before each use, inspect the entire product for damaged, missing, or loose parts such as screws, nuts, bolts, caps, etc. Tighten securely all fasteners and caps and do not operate this product until all missing or damaged parts are replaced.
Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc.

 WARNING
Do not at any time let brake fluids, gasoline, petroleumbased products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury.

Only the parts shown on the parts list are intended to be repaired or replaced by the customer. All other parts should be replaced at an Authorised Service Centre.

SPOOL REPLACEMENT

See Figure 10.

Use original manufacturer’s replacement cutting line for best performance.

■ Remove the battery pack.
■ Push in tabs on sides of spool cover.
■ Pull spool cover up to remove.
■ Remove the old spool.
■ To install the new spool, make sure the cutting line is captured in the slot on the new spool. Make sure the end of the cutting line is extended approximately 15cm beyond the slot.
■ Install the new spool so that the cutting line and slot align with the eyelet in the cutting head. Thread the cutting line into the eyelet.
■ Pull the cutting line extending from the cutting head so the cutting line releases from the slot in the spool.
■ Reinstall the spool cover by depressing tabs into slots and pushing down until spool cover clicks into place.

CUTTING LINE REPLACEMENT

See Figures 11-12.

■ Remove the battery pack.
■ Remove the spool from the cutting head.

NOTE: Remove any old cutting line remaining on the spool.

■ Cut two lines, each being approximately 10 ft. (3 m) long. Use only .065 in. (1.65 mm) diameter line.
■ Insert one line into the anchor hole in the upper part of the spool while the other line into the anchor hole in the bottom part of the spool. Wind the lines clockwise around the spool simultaneously, as shown by the arrows on the spool.
■ Replace the spool, and the spool cover. Refer to spool replacement earlier in this manual.

STORING THE TRIMMER

■ Remove the battery pack from the trimmer before storing.
■ Clean all foreign material from the trimmer.
■ Store it in a place that is inaccessible to children.
■ Keep away from corrosive agents such as garden chemicals and de-icing salts.
■ Store and charge your batteries in a cool area. Temperatures above or below normal room temperature will shorten battery pack life.
■ Never store batteries in a discharged condition. Wait for battery pack to cool and fully charge immediately.
■ Store the battery pack where the temperature is below 27˚C and away from moisture.
■ All batteries gradually lose their charge. The higher the temperature, the quicker they lose their charge. If you store your unit for long periods of time without using it, recharge the batteries every month or two. This practice will prolong battery pack life.

ENVIRONMENTAL PROTECTION

■ Environmental protection should be a priority of considerable importance when using the machine, for the benefit of both social coexistence and the environment in which we live. Try not to cause any disturbance to the surrounding area.
■ Scrupulously comply with local regulations for the disposal of packaging, deteriorated parts or any elements with a strong environmental impact; this waste must not be disposed of as normal waste, it must be separated and taken to specified waste disposal centres where the material will be recycled.
■ Scrupulously comply with local regulations for the disposal of waste materials after mowing.
■ At the time of decommissioning, do not pollute the environment with the machine, but hand it over to a disposal centre, in accordance with the local laws in force.
