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.

Installing or removing the bit

Clean the bit shank and apply bit grease before installing the
bit.

CAUTION:

•

Never use A-type shank bits. They can cause damage to
the tool.

Make sure that the

mark is visible on the top end of the

tool. If the

mark is not visible, pull the chuck cover down

until it is visible.

For drilling

Insert the bit into the tool. Turn the bit and push it in until it
engages.
