SPECIFIC SAFETY RULES FOR IMPACT WRENCH
Hold power tools by the insulated gripping surfaces when performing an
operation where the cutting tool may contact hidden wiring or its own
cord. Contact with a "live" wire will make exposed metal parts of the tool live
and shock the operator.
Do not use the power tool with a damaged
cord. Do not touch the
damaged cord; turn off the tool and pull the plug from the outlet if the
cord is damaged while working. Damaged cords increase the risk of an
electric shock.
Secure
the workpiece.
A workpiece
clamped
with clamping
devices
or in a
vice is held more securely than it is by hand.
Always wait until the power tool has come to a complete stop before
placing it down. The tool insert can jam and lead to loss of control over the
power tool.
Check the socket
carefully
for wear, cracks or damage
before installation
on the hammer drill.
Hold the tool firmly
with both hands.
Always
be sure that you have a firm footing.
Be sure that no one is below
you when using the tool in high locations.
Check the torque
with a torque
wrench.
The proper fastening
torque
may
differ depending
on the type of size of the bolt.
Use thick,
cushioned
gloves
and limit
the exposure
time
by taking
frequent
rest periods.
Vibration
caused
by hammer-drill
or Impact
wrench
action may be harmful to your hands and arms.
Do not use this tool as a drill. Tools equipped
with shut-off
clutches
are not
designed
for drilling applications.
The output drive can shut off automatically
and without
warning.
Be careful
when
driving
long screws.
There
is a risk of the tool sliding
off the fastener
head, depending
on type of socket
or bit used.
First test
the fastening
time of a fastener
and pay attention
during
the screw-driving
process to ensure you do not injure yourself
if the tool bit or socket slides off
of the fastener.
_.
WARNING:
Bits, sockets,
and tools get hot during operation.
Wear gloves
when touching
them.
_1_ WARNING:
Wear ear protection.
Exposure
to noise can cause
hearing loss.
A_, WARNING:
To avoid
injury,
hold the tool
by the insulated
gripping
surfaces
only.
If the tool contacts
hidden
wiring
or its
own cord, exposed
metal parts of the tool could
shock the operator
and cause
serious
injury.
Make sure that hidden
electrical
wiring,
water
pipes,
or other
hazards are not in the cutting
path.
