Notice on the action mode changing
knob operation
To avoid the damage to the mechanism of the action
mode changing knob, follow the procedures below:
•
Do not rotate the action mode changing knob
when the tool is running.
•
Make sure that the action mode changing knob is
always positively located in one of the three action
mode positions (

•
Do not turn the knob forcibly. Forcing the knob
may cause tool damage.
When turning the action mode changing knob from
the

Torque limiter
The torque limiter will actuate when a certain torque
level is reached. The motor will disengage from the out
-
put shaft. When this happens, the bit will stop turning.
CAUTION:
•
As soon as the torque limiter actuates, switch
off the tool immediately. This will help prevent
premature wear of the tool.
•
Hole saws cannot be used with this tool. They
tend to pinch or catch easily in the hole. This will
cause the torque limiter to actuate too frequently.
ASSEMBLY
CAUTION:
•
Always be sure that the tool is switched off and
the battery cartridge is removed before carrying
out any work on the tool.

the grip by turning clockwise at the desired position. It
may be swung 360° so as to be secured at any position.
Bit grease
Coat the bit shank head beforehand with a small
amount of bit grease (about 0.5 -1 g). This chuck lubri
-
cation assures smooth action and longer service life.
