SAFETY GUIDELINES:
WARNING!
Safety symbols in this Instruction Manual are used to flag possible dangers. The safety
symbols and their explanations require your full understanding. The safety warnings do not,
by themselves, eliminate any danger, nor are they substitutes for proper accident prevention
measures.
WARNING!
This Safety Alert Symbol indicates caution, warning, or danger. Failure to obey a safety
warning can result in serious injury to yourself or others. To reduce the risk of injury, fire, or
electric shock, always follow the safety precautions.
KNOW YOUR TOOL
To operate this tool, carefully read this Instruction Manual and all labels affixed to the cordless string
trimmer before using. Keep this instruction manual available for future reference.
IMPORTANT
This tool should only be serviced by a qualified service technician. For more information, call the
toll-free helpline at 1-800-689-9928.
READ ALL INSTRUCTIONS THOROUGHLY.

GENERAL POWER TOOL SAFETY WARNINGS
WARNING!
Read all safety warnings, instructions, illustrations and specifications provided with
this power tool. Failure to follow all instructions listed below may result in electric shock,
fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-
operated (cordless) power tool.
WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you
to lose control.
• Avoid dangerous environments. Don’t use appliances in damp or wet locations.

PERSONAL SAFETY
• Stay alert, watch what you are doing and use common sense when operating a power
tool. Do not use a power tool while you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention while operating power tools may result in
serious personal injury.
• Always use personal protective equipment. Personal protective equipment such as eye
protection, dust mask, non-skid safety shoes, hard hat and/or hearing protection used for
appropriate conditions will reduce personal injuries.
• Prevent unintentional starting. Ensure the switch is in the off-position before
connecting to power source and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energising power tools that have the
switch on invites accidents.
• Remove any adjusting key or wrench before turning the power tool on. A wrench or a
key left attached to a rotating part of the power tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing
away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
• If devices are provided for the connection of dust extraction and collection facilities,
ensure these are connected and properly used. Use of dust collection can reduce dust-
related hazards.
• Do not let familiarity gained from frequent use of tools allow you to become
complacent and ignore tool safety principles. A careless action can cause severe injury
within a fraction of a second.
POWER TOOL USE AND CARE
• Do not force the power tool. Use the correct power tool for your application. The correct
power tool will do the job better and safer at the rate for which it was designed.
• Do not use the power tool if the switch does not turn it on and off. Any power tool that
cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/or remove the battery pack,
if detachable, from the power tool before making any adjustments, changing
accessories, or storing power tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
• Store idle power tools out of the reach of children and do not allow persons unfamiliar
with the power tool or these instructions to operate the power tool. Power tools are
dangerous in the hands of untrained users.
• Maintain power tools and accessories. Check for misalignment or binding of moving
parts, breakage of parts and any other condition that may affect the power tool’s
operation. If damaged, have the power tool repaired before use. Many accidents are
caused by poorly maintained power tools.
SAFETY GUIDELINES

• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits, etc. in accordance with these
instructions, taking into account the working conditions and the work to be
performed. Use of the power tool for operations different from those intended could result in a
hazardous situation.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery
handles and grasping surfaces do not allow for safe handling and control of the tool in
unexpected situations.
• Keep cables away from the working area of the tool. During operation cables may be hidden
from view and can be accidentally damaged by the tool.
BATTERY TOOL USE AND CARE
• Recharge only with the charger specified by the manufacturer. A charger that is suitable
for one type of battery pack may create a risk of fire when used with another battery pack.
• Use power tools only with specifically designated battery packs. Use of any other battery
packs may create a risk of injury and fire.
• When battery pack is not in use, keep it away from other metal objects, like paper
clips, coins, keys, nails, screws or other small metal objects, that can make a
connection from one terminal to another. Shorting the battery terminals together may cause
burns or a fire.
• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If
contact accidentally occurs, flush with water. If liquid contacts eyes, seek additional
medical help. Liquid ejected from the battery may cause irritation or burns.
• Do not use a battery pack or tool that is damaged or modified. Damaged or modified
batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
• Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or
temperature above 130°C (265°F) may cause an explosion.
• Follow all charging instructions and do not charge the battery pack or tool outside the
temperature range specified in the instructions. Charging improperly or at temperatures
outside the specified range may damage the battery and increase the risk of fire.
SERVICE
• Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
• Never service damaged battery packs. Service of battery packs should only be performed by
the manufacturer or authorized service providers.
ADDITIONAL SAFETY GUIDELINES
• The label on your tool may include the following symbols. The symbols and their
definitions are as follows:

• When replacing the cutting line, use no more than 0.08” (2.0 mm) 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.
• 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.
• For best results, your battery and tool should be stored, charged and used in a location where
the temperature is more than 5°C (41°F) but less than 40°C (104°F).Do not store outside or in
vehicles .

TO START/STOP THE GRASS TRIMMER
(fig 8)
Before starting the grass trimmer:
• Make sure that you have a secure and balanced
footing.
• Stand upright and hold the grass trimmer in a
relaxed position.
• Make sure that the cutting line is not touching
the ground or any other objects.
• Hold the grass trimmer with both hands: one
hand on the rear handle and the other hand on
the front-assist handle.
1. To turn the grass trimmer on, press the lock-off button and then depress the variable-speed trigger switch.
2.
The variable-speed trigger switch delivers higher speed with increased trigger pressure and lower speed
with decreased trigger pressure.
3.
To turn the grass trimmer off, release the variable-speed trigger switch and allow the trimmer to come to
a complete stop.
TIPS FOR USING THE GRASS TRIMMER
(fig 9)
• To avoid serious personal injury, wear safety
glasses, face mask, proper clothing and
footwear at all times when operating this unit.
• 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.
• 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 of the line will reduce cutting efficiency and may overload
the motor.
• Grass over 8” (20 cm) 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 while maintaining the cutting head
position at the desired cutting height. Cutting shorter lengths produces best results.
• Trim only when grass and weeds are dry.
• Avoid trees and shrubs. Tree bark, wood moldings, siding, and fence posts can easily be damaged
by the strings.

ADJUSTING THE CUTTING LINE LENGTH
(fig 10)
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 bump knob on the
ground while operating the trimmer.
For best results, tap the bump knob 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.

MAINTENANCE
CHECK FOR DAMAGED/WORN PARTS BEFORE EACH USE
Check the bump head, guard, and front-assist handle, and 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.
CLEAN THE TRIMMER AFTER EACH USE
1. Clear any grass that may have wrapped itself around the motor shaft or trimmer head.
2.
Use only a clean, dry and soft cloth to clean the tool. Never let any liquid get inside the tool; never immerse any part
of the tool into a liquid.
3.
Always keep the air vents in the rear housing free from debris.
STORAGE
Clean the tool thoroughly before storing it. Store the unit in a dry, well-ventilated area, locked-up or up
high, and out of the reach of children. Keep away from corrosive agents, such as garden chemicals and
de-icing salts.
WARNING!
• Do not let brake fluids, gasoline, petroleum-based products, penetrating oil, etc., come into contact with
plastic parts. These substances contain chemicals that can damage, weaken, or destroy plastic.
• When servicing, use only identical replacement parts. The use of any other parts may create a hazard or
cause damage to the product.
• Use only accessories that are recommended for this string trimmer by the manufacturer. Accessories that
may be suitable for one tool may become hazardous when used with another tool.
• To ensure safety and reliability, all repairs should be performed by a qualified service technician.
