The side handle can be swung 360° on the vertical and
secured at any desired position. It also secures at eight
different positions back and forth on the horizontal. Just
loosen the clamp nut to swing the side handle to a
desired position. Then tighten the clamp nut securely.

CAUTION:
Always use the side grip to ensure operating safety
•
when drilling in concrete, masonry, etc.
The side grip swings around to either side, allowing easy
handling of the tool in any position. Loosen the side grip
by turning it counterclockwise, 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 longer service
life.
