• Do not allow children or untrained individuals to use this unit.

• Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

• Do not handle battery or tool with wet hands.

• Never allow children to operate the equipment. Never allow adults to operate the equipment without proper instruction.

• Always wear safety glasses with side shields that are marked to comply with ANSI Z87.1. Everyday glasses have only impact resistant lenses. They are NOT safety glasses. Following this rule will reduce the risk of eye injury. Use face mask if operation is dusty.

• Don’t use in the rain. Store indoors.

• Do not operate in poor lighting.

• Keep all parts of your body away from any moving part.

• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to battery pack, picking up or carrying the appliance. Carrying the appliance with your finger on the switch or energizing appliance that have the switch on invites accidents.

• Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.

• Do not operate the equipment while bare foot or when wearing sandals or similar lightweight footwear. Wear protective footwear that will protect your feet and improve your footing on slippery surfaces.

• Keep firm footing and balance. Do not overreach. Overreaching can result in loss of balance.

• Check Damaged Parts – Before further use of the appliance, 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.

• Keep guards in place and in working order.

• Keep hands and feet away from cutting area.

• Do not allow to be used as a toy. Close attention is necessary when used by or near children.

• Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired.

• Do not place battery tools or their batteries near fire or heat. This will reduce the risk of explosion and possibly injury.

• Batteries can explode in the presence of a source of ignition, such as pilot light. To reduce the risk of serious personal injury, never use any cordless product in the presence of an open flame. An ex ploded battery can propel debris and chemicals. If exposed, flush with water immediately.

• 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.

• Under extreme usage or temperature conditions, battery leakage may occur. If liquid comes in contact with your skin, wash immediately with soap and water, then neutralize with lemon juice or vinegar. If liquid gets into your eyes, flush them with clean water for at least 10 minutes, then seek immediate medical attention. Following this rule will reduce the risk of serious personal injury.

gets worn down and becomes shorter. This trimmer

is equipped with bump feed line advancement,

which advances additional line once the head is

swath.

Bump knob

OPERATING INSTRUCTIONS

Trimmer tips

Before each use:

• Make sure the protective guard is tightly installed. If not, tighten the guard screws.

• Before trimming, inspect the area for string, wire, branches or other material that may become entangled in the cutting line and thrown.

Storage tips:

• Do not store the grass trimmer/edger in sunlight, in an excessively warm place, or near a furnace.

The battery life will be shortened.

During use:

• Trim only when the grass and weeds are dry.

• Do not trim grass at night. Always make sure you have

adequate lighting.

• Hold the grass trimmer/edger by both the switch handle

and the auxiliary handle for best control and balance.

• Stand with the cutting head tipped down at an angle in

front, guiding the grass trimmer/edger in a semicircular

motion around you.

• If possible, guide the grass trimmer/edger to the left to

cut. The line will cut as soon as it leaves the guard, and

the clippings are thrown away from you.

• To produce a smoothly trimmed area, move the grass

trimmer/edger out of the area being cut with consistent

speed and height.

• Use only the tip of the cutting line to do the trimming, especially near walls and fences. Trimming with the side of the cutting line may overload the motor, wear out the line faster, and break the line more often.

• Do not rest the trimmer spool on the ground while trimming. This will cause spool wear and battery drain.

• If the grass is higher than 6 in. (15 cm), trim in small stages.

• When the grass trimmer/edger is turned off and the spool stops rotating, the cutting line will relax and may recede. Feed extra cutting line before storing the trimmer to prevent losing the line completely into the spool.

• If the diameter of the cutting area gets smaller, the line is worn down and needs to be advanced more often.

• If the grass trimmer/edger is not cutting correctly, the cutting line may not be feeding properly.

• Remove and rewind the line spool.

CARE AND MAINTENANCE

Trimmer Guard and Motor Maintenance

Note: Before performing maintenance, remove battery from the tool.

1. Remove dirt and debris from guard using a paint brush

(not included).

2. Clean dirt and debris off of motor cover and

connection joints.

3. Clean the grass in the air vents after trimming.

4. Clean line cutter blades by using a wire brush and

spraying with an appropriate degreaser.

CARE AND MAINTENANCE
