Grease
Optional accessory
Coat the shank end of the drill bit beforehand with a
small amount of grease (about 0.5 - 1 g).
This chuck lubrication assures smooth action and lon-
ger service life.
Installing and removing drill bit
Clean the shank end of the drill bit and apply grease
before installing the drill bit.
