ADDITIONAL
SAFETY RULES
1)
Use auxiliary handle (support
handle) supplied with the tool.
Loss of control can cause personal
injury.
2) Be aware that this tool is always
in an operating condition, since it
does not have to be plugged into
an electrical outlet.
3)
Hold power tools by insulat-
ed gripping surfaces when per-
forming 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 opera-
tor.
4) If the bit becomes jammed, im-
mediately turn the main switch off
to prevent an overload which can
damage the battery pack or mo-
tor. Use reverse motion to loosen
jammed bits.
5)
Do not operate the Forward/Reverse
lever when the main switch is on. The
battery will discharge rapidly and dam-
age to the unit may occur.
6) Use only a dry, soft cloth for wiping
the unit. Do not use a damp cloth,
thinner, benzine, or other volatile
solvents for cleaning.
7)
When storing or carrying the tool, set
the Forward/Reverse lever to the cent-
er position (switch lock).
8) Do not strain the tool by holding
the speed control trigger halfway
(speed control mode) so that the
motor stops. The protection cir-
cuit will activate and may prevent
speed control operation. If this hap-
pens, release the speed control
trigger and squeeze again for nor-
mal operation.
9) Be careful not to get dust inside the
chuck.
10) Do not touch the rotating parts to
avoid injury.
11) 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.
12) Do not drop the tool.
13) Wear ear protection. Exposure to
noise can cause hearing loss.
14) Do not put the tool on the place
where the chuck cover is de-
pressed. The bit may come off
from the chuck cover and fall
down when the chuck cover is de-
pressed. It may cause injuries.
