Projectile hazards
• Always wear impact-resistant eye and face pro-
tection when involved with or near the opera-
tion, repair or maintenance of the tool or
changing accessories on the tool.
• Be sure all others in the area are wearing im-
pact-resistant eye and face protection. Even
small projectiles can injure eyes and cause
blindness.
• Remove the chuck key before starting the tool.
• Ensure that the workpiece is securely fixed.
Operating hazards
• Operators and maintenance personnel must be
physically able to handle the bulk, weight and
power of the tool.
• Hold the tool correctly: be ready to counteract
sudden movements, particularly at drill bit
breakthrough.
• The drill bit can suddenly bind and cause the
work piece or tool to rotate, causing arm or
shoulder injuries.
• If possible, use a suspension arm to absorb the
reaction torque. If that is not possible, side han-
dles are recommended to absorb the reaction
torque for:
• Straight case drills with a chuck capacity larger
than 6.5 mm. (1/4 inch), or if the torque reac-
tion might exceed 4 Nm (3 lbf.ft);
• Pistol-grip drills with a chuck capacity larger
than 10 mm. (3/8 inch), or if the torque reaction
might exceed 10 Nm (7.5 lbf.ft).
• Always use sharp bits.
• Reduce downward pressure at breakthrough.
Repetitive motion hazards
• When using a power tool to perform work-re-
lated activities, the operator might experience
discomfort in the hands, arms, shoulders, neck,
or other parts of the body.
• Adopt a comfortable posture whilst maintain-
ing secure footing and avoiding awkward or
off-balance postures. Changing posture during
extended tasks can help avoid discomfort and
fatigue.
• Do not ignore symptoms such as persistent or
recurring discomfort, pain, throbbing, aching,
tingling, numbness, burning sensation, or stiff-
ness. Stop using the tool, tell your employer
and consult a physician.

Noise and Vibration hazards
• High sound levels can cause permanent hearing
loss and other problems such as tinnitus. Use
hearing protection as recommended by your
employer or occupational health and safety reg-
ulations.
• Exposure to vibration can cause disabling dam-
age to the nerves and blood supply of the hands
and arms. Wear warm clothing and keep your
hands warm and dry. If numbness, tingling,
pain or whitening of the skin occurs, stop using
tool, tell your employer and consult a physi-
cian.
• Hold the tool in a light but safe grip because
the risk from vibration is generally greater
when the grip force is higher. Where possible
use a suspension arm or fit a side handle.
• To prevent unnecessary increases in noise and
vibration levels:
• Operate and maintain the tool, and select,
maintain and replace the accessories and con-
sumables, in accordance with this instruction
manual;
• Do not allow the drill bit to chatter on the
workpiece.
Workplace hazards
• Slip/Trip/Fall is a major cause of serious injury
or death. Be aware of excess hose left on the
walking or work surface.
• Avoid inhaling dust or fumes or handling de-
bris from the work process which can cause ill
health (for example, cancer, birth defects,
asthma and/or dermatitis). Use dust extraction
and wear respiratory protective equipment
when working with materials which produce
airborne particles.
• Some dust created by power sanding, sawing,
grinding, drilling and other construction activi-
ties contains chemicals known to the State of
California to cause cancer and birth defects or
other reproductive harm. Some examples of
these chemicals are:
• Lead from lead based paints
• Crystalline silica bricks and cement and
other masonry products
• Arsenic and chromium from chemically-
treated rubber
