speeds for a long time, the motor will get over-
loaded, resulting in tool malfunction.

Side grip (auxiliary handle)

► 1. Side grip
For maximum control and safer operation, always use
the side grip with this tool. The side grip swings around
to either side, allowing easy handling of the tool in any
position. Loosen the side grip by turning it counterclock-
wise, swing it to the desired position and then tighten it
by turning clockwise.
Bit grease (optional accessory)
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 lon-
ger service life.
Installing or removing the bit
