I. INTENDED USE
This tool is a Rotary Hammer for
drilling in concrete. In addition, the tool
has a “rotation only mode” without
hammering. The mode is suitable for
drilling and screw-fastening.
Read “Safety Instructions” booklet and
the following before using.
II. ADDITIONAL
SAFETY RULES
1) Wear ear protection. Exposure to
noise can cause hearing loss.
2) Use auxiliary handle (support
handle) supplied with the tool.
Loss of control can cause personal
injury.
3) Hold power tools by insulated
gripping surfaces when
performing an operation where
the cutting tool may contact
hidden wiring; contact with a
“live” wire will make exposed
metal parts of the tool “live” and
shock the operator.
4) Wear a dust mask, if the work
causes dust.
5) Be aware that this tool is always
in an operating condition, since it
does not have to be plugged into
an electrical outlet.
6) If the bit becomes jammed,
immediately turn the main switch
off to prevent an overload which
can damage the battery pack or
motor. Use reverse motion to
loosen jammed bits.
7) Do not operate the Forward/Reverse
lever when the main switch is on. The
battery will discharge rapidly and
damage to the unit may occur.
8) Use only a dry, soft cloth for
wiping the unit. Do not use a damp
cloth, thinner, benzine, or other
volatile solvents for cleaning.
9) When storing or carrying the tool, set
the Forward/Reverse lever to the
center position (switch lock).
10) Do not strain the tool by holding the
speed control trigger halfway (speed
control mode) so that the motor
stops. The protection circuit will
activate and may prevent speed
control operation. If this happens,
release the speed control trigger and
squeeze again for normal operation.
11) Be careful not to get dust inside the
chuck.
12) Do not touch the rotating parts to
avoid injury.
13) Do not continue to use the tool for
a long time. Stop using the tool
from time to time to avoid that the
temperature of the motor rises too
high.
14) Do not drop the tool.
15) Do not put the tool on the place
where the chuck is depressed. The
bit may come off from the chuck
and fall down when the chuck is
depressed. It may cause injuries.
