PERSONAL CONDITION & SAFETY EQUIPMENT
W ARNING DANGER
Trimmer/Brush Cutter users risk injury to themselves and others if the trimmer/brush cutter is used improperly and or
safety precautions are not followed. Proper clothing and safety gear must be worn when operating a trimmer.
Physical Condition --

- if you are tired or sick,
- if you are taking medication,

GRASS TRIMMER/BRUSH CUTTER
Eye Protection --
Wear eye protection that meets ANSI Z87.1 or CE requirements
whenever you operate the trimmer.

Brush Cutter handles. Gloves also reduce the transmission of machine
vibration to your hands.

SAFE OPERATION
Determine Operation Area
- Provide all operators of this equipment with the operator's manual and
instructions for safe operation.
- Review the area to be trimmed. Look for hazards that could
contribute to unsafe conditions.
- Spectators and fellow workers must be warned, and children and
animals prevented from coming nearer than 15M (50 ft.) while
the trimmer is in use.
Operation
Use Proper Clothing & Equipment
- Before starting the unit, equip yourself and any other personworking
within the 15M (50 ft.) Safety Zone with the required Protective
Equipment and clothing.
Avoid Hot Surfaces
- During operation, the complete unit, especially the drive shaft
housing and the bearing housing may become very hot, too hot to
touch. Avoid contact during and immediately after operation.
15M
(50 ft.)
Keep A Firm Grip
- Hold the front and rear handles with both hands with thumbs and
fingers encircling the handles.
Keep A Solid Stance
- Maintain footing and balance at all times. Do not stand on slippery,
uneven or unstable surfaces. Do not work in odd positions or on
ladders. Do not over reach.
GRASS TRIMMER/BRUSH CUTTER
EXTENDED OPERATION/EXTREME CONDITIONS
Vibration and Cold --
It is believed that a condition called Raynaud’s Phenomenon, which
affects the fingers of certain individuals may be brought about by
exposure to vibration and cold. Exposure to vibration and cold may
cause tingling and burning sensations followed by loss of color and
numbness in the fingers. The following precautions are strongly
recommended because the minimum exposure which might trigger the
ailment is unknown.
• Keep your body warm, especially the head, neck, feet, ankles,
hands and wrists.
• Maintain good blood circulation by performing vigorous arm
exercises during frequent work breaks and also by not smoking.
• Limit the hours of operation. Try to fill each day with jobs where
operating the trimmer or other hand-held power equipment is not
required.
• If you experience discomfort, redness and swelling of the fingers
followed by whitening and loss of feeling, consult your physician
before further exposing yourself to cold and vibration.
OPERATOR'S MANUAL
9
Repetitive Stress Injuries --
It is believed that overusing the muscles and tendons of the fingers,
hands, arms and shoulders may cause soreness, swelling, numbness,
weakness and extreme pain in those areas. Certain repetitive hand
activities may put you at a high risk for developing a Repetitive Stress
Injury (RSI). An extreme RSI condition is Carpal Tunnel Syndrome
(CTS), which could occur when your wrist swells and squeezes a vital
nerve that runs through the area. Some believe that prolonged exposure
to vibration may contribute to CTS. CTS can cause severe pain for
months or even years. To reduce the risk of RSI/CTS, do the following:
• Avoid using your wrist in a bent, extended or twisted position.
Instead try to maintain a straight wrist position. Also, when grasping,
use your whole hand, not just the thumb and index finger.
• Take periodic breaks to minimize repetition and rest your hands.
• Reduce the speed and force with which you do the repetitive
movement.
• Do exercises to strengthen the hand and arm muscles.
• Immediately stop using all power equipment and consult a doctor if
you feel tingling, numbness or pain in the fingers, hands, wrists or
arms. The sooner RSI/CTS is diagnosed, the more likely permanent
nerve and muscle damage can be prevented.
