output 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.

CAUTION:
Always use the side grip to ensure operating
•
safety.
Install the side grip so that the teeth on the grip fit in
between the protrusions on the tool barrel. Then tighten
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; 0.02 - 0.04 oz.).
This chuck lubrication assures smooth action and longer
service life.
Installing or removing the bit
Clean the bit shank and apply bit grease before
installing the bit.
