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. Mounting the drill bit
○ To prevent accidents, make sure to turn the switch off
and disconnect the plug from the receptacle.
○ When using tools such as bull points, drill bits, etc.,
make sure to use the genuine parts designated by our
company.
○ Clean the shank portion of the drill bit.
○ Check the latching by pulling on the drill bit.
9. To prevent accidents, make sure to turn the switch off
and disconnect the plug from the receptacle when the
drill bits and other various parts are installed or removed.
The power switch should also be turned off during a work
break and after work.
10. Rotation + hammering
When the drill bit touches construction iron bar, the bit
will stop immediately and the rotary hammer will react to
revolve. Therefore fi rmly tighten the side handle.
11. Rotation only
To drill wood or metal material using the drill chuck and
chuck adapter (optional accessories).
○ Application of force more than necessary will not only
expedite the work, but will deteriorate the tip edge of the
drill bit and reduce the service life of the rotary hammer
in addition.
○ Drill bits may snap off while withdrawing the rotary
hammer from the drilled hole. For withdrawing, it is
important to use a pushing motion.
○ Do not attempt to drill anchor holes or holes in concrete
with the machine set in the rotation only function.
○ Do not attempt to use the rotary hammer in the rotation
and striking function with the drill chuck and chuck
adapter attached. This would seriously shorten the
service life of every component of the machine.
