ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Side handle
CAUTION:
Use the side handle only when chipping, scaling or
demolishing. Do not use it when drilling in concrete,
masonry, etc. The tool cannot be held properly with this
side handle when drilling.
The side handle can be swung 360° on the vertical and
secured at any desired position. It also secures at eight dif-
ferent 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.
Side grip
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 lubri-
cation assures smooth action and longer service life.
