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

lubrication assures smooth action and longer service

life.

held in place by trying to pull it out.
