Wear non-slip, heavy-duty work gloves to  
improve your grip on the engine drill handles.  
The gloves also help reduce the transmission  
of machine vibrations to your hands.  
WARNING  
PRECAUTION AGAINST 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  
PROTECTING OTHERS  
Spectators, children, fellow workers and animals  
must be warned to come no nearer than 4.6 m (15  
feet) while the engine drill is in use.  
People working in the area near you should wear  
the same protective equipment as the operator.  
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.  
PHYSICAL CONDITION  
Your judgement and dexterity may be impaired if  
you are ill or have taken alcohol or other  
substances known to affect the way you would  
normally function.  
• 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 ENGINE DRILL 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.  
Painful or numb fingers?

Repetitive Stress Injuries  
It is believed that over-using 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 exercise to strengthen the hand and arm  
muscles.  
See 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.  
OPERATING TECHNIQUES  
When starting to drill, run the engine at full  
throttle.  
Do not attempt to repair the machine unless  
you are qualified to do so.  
WARNING  
Do not operate the machine with a damaged or  
excessively worn drill bit.  
BEFORE DRILLING, BE SURE TO READ AND  
UNDERSTAND THE ENTIRE OPERATOR’S  
MANUAL TO AVOID THE CHANCE OF  
SERIOUS INJURY.  
Always ensure all handles and guards are  
fitted when using the machine. Never attempt  
to use an incomplete machine or one fitted with  
an unauthorized modification.  
Do not force the drills and only move as  
quickly as the drills will allow.  
When transporting or storing the machine  
always remove the drill bit.  
Stop the engine and disconnect from ignition  
cable before: - cleaning or when clearing a  
blockage; checking, maintenance or working  
on the machine.  
To reduce fire hazard keep engine and silencer  
free of debris, leaves or excessive grease.  
Handle drill with care, contacting with drills  
may cause injury.  
Handle fuel with care; it is highly flammable.  
Never add fuel to a machine with a running or  
hot engine.
