4) When battery pack is not in use,
keep it away from other metal ob-
jects like paper clips, coins, keys,
nails, screws, or other small metal
objects that can make a connection
from one terminal to another.
Shorting the battery terminals to-
gether may cause burns, or a fire.
5) Under abusive conditions, liq-
uid may be ejected from battery;
avoid contact. If contact acciden-
tally occurs, flush with water. If
liquid contacts eyes, additionally
seek medical help.
Liquid ejected from the battery may
cause irritation or burns.
Service
1) Have your power tool serviced by
a qualified repair person using
only identical replacement parts.
This will ensure that the safety of
power tool is maintained.
III. SPECIFIC SAFE-
TY RULES
1) Wear ear protectors. Exposure to
noise can cause hearing loss.
2) Use auxiliary handles supplied
with the tool. Loss of control can
cause personal injury.
3) Hold power tools by insulated
grip ping sur faces when perform-
ing an operation where the cutting
tool may contact hid den wiring.
Contact with a "live" wire will make
ex posed metal parts of the tool
"live" and shock the operator.
4) Be aware that this tool is always in
an operating condition, since it does
not have to be plugged into an elec-
trical outlet.
5) If the bit becomes jammed, imme-
diately turn the trigger switch off
to prevent an overload which can
damage the battery pack or mo-
tor. Use reverse motion to loosen
jammed bits.
6) Do not operate the Forward/Reverse
lever when the trigger switch is on.
The battery will discharge rapidly
and damage to the unit may occur.

7) When storing or carrying the tool,
set the Forward/Reverse lever to
the center position (switch lock).
8) Do not strain the tool by hold-
ing the speed control trigger half-
way (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.
Do not use the tool continuously for a
11)
long period of time. Stop using the tool
from time to time to avoid temperature
rise and heat overload of the motor.
12) Do not drop the tool.
13) Wear dust mask, if the work causes
dust.
14) During charging, the charger may be-
come slightly warm. This is normal.
