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.
• Do not force the drills and only move as
quickly as the drills will allow.
• Stop the engine and disconnect from ignition
cable before: - cleaning or when clearing a
blockage; checking, maintenance or working
on the machine.
• Handle fuel with care; it is highly flammable.
Never add fuel to a machine with a running or
hot engine.
• When starting to drill, run the engine at full
throttle.
• Do not attempt to repair the machine unless
you are qualified to do so.
• Do not operate the machine with a damaged or
excessively worn drill bit.
• 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.
• When transporting or storing the machine
always remove the drill bit.
• 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.
