SAFETY GUIDELINES
ELECTRICAL SAFETY
•
Machine plugs must match the outlet. Never modify the plug in any way. Do not use
any adaptor plugs with earthed (grounded) machines. Unmodified 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 machines to rain
or wet conditions.
Water entering a machine will increase
continuation
tabs
continuation
tabs
the risk of electric shock.
•
Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the
machine. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
•
When operating a machine outdoors, use an extension cord suitable for outdoor use.
Use of a cord suitable for outdoornotes
use reduces the risk of electric shock.
notes
•
If operating a machine 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
machine. Do not use a machine while you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention while operating machines may result in serious
personal injury.
•
Use personal protective equipment. Always wear eye protection. Protective equipment
warnings
warnings
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 machines with your finger on the switch or energising machines that have the switch on
invites accidents.
•
Remove any adjusting key or wrench before turning the machine on. A wrench or a key
left attached to a rotating part of the machine may result in personal injury.
•
Do not overreach. Keep proper footing and balance at all times. This enables better
control of the machine 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 dustrelated 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.
7
•
Do not force the machine. Use the correct machine for your application. The correct
machine will do the job better and safer at the rate for which it was designed.
•
Do not use the machine if the switch does not turn it on and off. Any machine 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 machine before making any adjustments, changing accessories,
or storing machines. Such preventive safety measures reduce the risk of starting the machine
accidentally.
•
Store idle machines out of the reach of children and do not allow persons unfamiliar
with the machine or these instructions to operate the machine. Machines are dangerous
in the hands of untrained users.
•
Maintain machines and accessories. Check for misalignment or binding of moving
parts, breakage of parts and any other condition that may affect the machine’s
operation. If damaged, have the machine repaired before use. Many accidents are caused
by poorly maintained machines.
•
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 machine, accessories, tool bits, etc., in accordance with these instructions,
taking into account the working conditions and the work to be performed. Use of the
machine 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 machines 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.

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 and the cutter
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 flying 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 lines.
•
While operating the machine, always wear safety footwear. Do not operate the
machine when barefoot or wearing open sandals. This reduces the chance of injury to the
feet from contact with a line.
•
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—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.
warnings
warnings
•
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 line when the machine is operating.
Before you start the machine, make sure line 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 line 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 fibres 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
line and be whipped toward you or pull you off balance.
•
Maintain control of the machine and do not touch lines and other hazardous moving
parts while they are still in motion. This reduces the risk of injury from moving parts.
•
When clearing jammed material or servicing the machine, make sure all power
switches are off and the battery is disconnected. Unexpected starting of the machine while
clearing jammed material or servicing may result in serious personal injury.
•
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 line.
•
Only use replacement lines and cutting heads specified by the manufacturer. Incorrect
replacement parts may increase the risk of breakage and injury.
•
If you strike a foreign object with the trimmer or it becomes entangled, stop the
tool immediately, check for damage and have any damage repaired before further
operation is attempted. Do not operate with a broken guard or spool.
•
If machine starts to vibrate abnormally, stop the motor and check immediately for
the cause. Vibration is generally a warning of trouble. A loose head may vibrate, crack, break
or come off the trimmer, which may result in serious or fatal injury. Make sure that the cutting
attachment is properly fixed in position. If the head loosens after fixing it in position, replace it
immediately. Never use a trimmer with a loose cutting attachment.

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.

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.
