ROTARY HAMMER SAFETY
WARNINGS
1. Wear ear protectors
Exposure to noise can cause hearing loss.
2. Use auxiliary handle(s), if supplied with the tool.
Loss of control can cause personal injury.
3. Hold power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring or its own
cord.
Cutting accessory contacting a "live" wire may make
exposed metal parts of the power tool "live" and could
give the operator an electric shock.
ADDITIONAL SAFETY WARNINGS
1. Ensure that the power source to be utilized conforms
to the power requirements specifi ed on the product
nameplate.
2. Ensure that the power switch is in the OFF position.
If the plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, which could cause a serious
accident.
3. When the work area is removed from the power source,
use an extension cord of suffi cient thickness and rated
capacity. The extension cord should be kept as short as
practicable.
4. Do not touch the bit during or immediately after
operation. The bit becomes very hot during operation
and could cause serious burns.
5. Before starting to break, chip or drill into a wall, fl oor or
ceiling, thoroughly confi rm that such items as electric
cables or conduits are not buried inside.
6. Always hold the body handle and side handle of the
power tool fi rmly. Otherwise the counterforce produced
may result in inaccurate and even dangerous operation.
7. Wear a dust mask
Do not inhale the harmful dusts generated in drilling or
chiseling operation. The dust can endanger the health of
yourself and bystanders.
8. For tools such as a bull point and a cold chisel, use only
Hitachi genuine parts.
9. Do not adjust the dial during operation. Doing so can
result in injury because the Rotary Hammer must be
held by only one hand, disabling the steady control of
the Rotary Hammer.
10. Although this machine is equipped with a safety clutch, if
the drill bit becomes bound in concrete or other material,
the resultant stoppage of the drill bit could cause the
machine body to turn in reaction. Ensure that the
main handle and side handle are gripped fi rmly during
operation.
11. If you switch the selector lever during motor rotation, the
tool can start to rotate abruptly, resulting in unexpected
accidents. Be sure to switch the selector lever when the
motor is at a complete stop.
12. After switching the selector lever, verify that the lever
doesn't rotate without pressing the button to make sure
that the lever is completely locked.
13. If the selector lever is switched during motor rotation, the
tool can start to rotate abruptly, resulting in unexpected
accidents. Make sure to switch the selector lever when
the motor is at a complete stop.
14. If the bull point or cold chisel is used at the position of
"rotation + hammering", the tool can start to rotate,
resulting in unexpected accidents. Make sure that they
are used at the position of "hammering".
15. During operation, be sure to grip the handle and the side
handle fi rmly to prevent your body from swaying.
16. Prior to mounting tools such as a bull point, cold chisel
or core bit, always disconnect the plug from the power
supply receptacle.
17. When removing the center pin and guide plate, always
disconnect the plug from the receptacle.
18. RCD
The use of a residual current device with a rated residual
current of 30 mA or less at all times is recommended.
