General Power Tool Safety Warnings
WARNING
• Read all safety warnings, instructions, illustrations and specications provided with
this power tool. Failure to follow all instructions listed below may result in electric shock,
re 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
ammable 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.
Electrical Safety
• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use
any adapter plugs with earthed (grounded) power tools. Unmodied plugs and matching
outlets will reduce risk of electric shock.
• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your body is
earthed or grounded.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
6
SAFETY INFORMATION
• When operating a power tool outdoors, use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is unavoidable, use a ground fault circuit
interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.
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 inuence of drugs,
alcohol or medication. A moment of inattention while operating power tools may result in
serious personal injury.

such as a dust mask, non-skid safety shoes, hard hat 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 nger 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 jewelry. Keep your hair and clothing
away from moving parts. Loose clothes, jewelry 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.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control.
7
SAFETY INFORMATION
• 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

Service
• Have your power tool serviced by a qualied 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.
Grass Trimmer Safety Warnings
• Do not use the machine in bad weather conditions, especially when there is a risk of
lightning. This decreases the risk of being struck by lightning.
• Thoroughly inspect the area for wildlife where the machine is to be used. Wildlife may
be injured by the machine during operation.
• Thoroughly inspect the area where the machine is to be used and remove all stones,
sticks, wires, bones, and other foreign objects. Thrown objects can cause personal
injury.
• Before using the machine, always visually inspect to see that the cutter or blade and
the cutter or blade assembly are not damaged. Damaged parts increase the risk of injury.
• Follow instructions for changing accessories. Improperly tightened blade securing nuts
or bolts may either damage the blade or result in it becoming detached.
• Wear eye, ear, head and hand protection. Adequate protective equipment will reduce
personal injury by ying debris or accidental contact with the cutting line or blade.
• While operating the machine, always wear non-slip and protective footwear. Do not
operate the machine when barefoot or wearing open sandals. This reduces the chance
of injury to the feet from contact with the moving cutters or lines.
8
SAFETY INFORMATION
• While operating the machine, always wear long trousers. Exposed skin increases the
likelihood of injury from thrown objects.
• Keep bystanders away while operating the machine. Thrown debris can result in serious
personal injury.
• Always use two hands when operating the machine. Holding the machine with both
hands will avoid loss of control.
• Hold the machine by the insulated gripping surfaces only, because the cutting line or
blade may contact hidden wiring. Cutting line or blades contacting a “live” wire may make
exposed metal parts of the machine “live” and could give the operator an electric shock.
• Always keep proper footing and operate the machine only when standing on the
ground. Slippery or unstable surfaces may cause a loss of balance or control of the
machine.
• Do not operate the machine on excessively steep slopes. This reduces the risk of loss
of control, slipping and falling which may result in personal injury.
• When working on slopes, always be sure of your footing, always work across the face
of slopes, never up or down and exercise extreme caution when changing direction.
This reduces the risk of loss of control, slipping and falling which may result in personal
injury.
• Keep all parts of the body away from the cutter, line or blade when the machine is
operating. Before you start the machine, make sure the cutter, line or blade is not
contacting anything. A moment of inattention while operating the machine may result in
injury to yourself or others.
• Do not operate the machine above waist height. This helps prevent unintended cutter or
blade contact and enables better control of the machine in unexpected situations.
• When cutting brush or saplings that are under tension, be alert for spring back. When
the tension in the wood bres is released, the brush or sapling may strike the operator and/
or throw the machine out of control.
• Use extreme caution when cutting brush and saplings. The slender material may catch
the blade and be whipped toward you or pull you off balance.
• Maintain control of the machine and do not touch cutters, lines or blades and other
hazardous moving parts while they are still in motion. This reduces the risk of injury
from moving parts.
• Carry the machine with the machine switched off and away from your body. Proper
handling of the machine will reduce the likelihood of accidental contact with a moving cutter,
line or blade.
• Only use replacement cutters, lines, cutting heads and blades specied by the
manufacturer. Incorrect replacement parts may increase the risk of breakage and injury.
• When clearing jammed material or servicing the machine, make sure the switch is
off and the battery pack is removed. Unexpected starting of the machine while clearing
jammed material or servicing may result in serious personal injury.

OPERATING INSTRUCTIONS
Tips for best trimming results
• 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 efciency and may overload the
motor.
• The cutting height is determined by the distance of the cutting line from the lawn surface.
• Grass over 8 in. (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, 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 (Fig. 8b)
The cutting 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 head (G)
on the ground while operating the trimmer.
For best results, tap the bump 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 difcult as the cutting line
becomes shorter.
