Always disconnect the plug from the socket before carrying out any work on the
machine.
Usually, the chuck can be removed by
hand: steady the drill spindle with a fork
wrench and unscrew the chuck by turning
it anti–clockwise.
Should the chuck be stuck on the drill
spindle, fit another fork wrench to the
chuck (see illustration) or fix an Allen key
in the chuck.
If necessary, hit the key shaft lightly with a
plastic hammer.
Mount the chuck in reverse order.
Under high strain in anti–clockwise operation, the chuck might become loose.
Please use the bit reception to loosen screws in anti–clockwise operation.
Completely insert the tool shaft into the
open chuck.
Hold the grip and firmly tighten the chuck
by turning the sleeve in the "GRIP"
direction.
After the clamping jaws have tightened
around the tool shaft, turn the chuck a
further 1/4 in order to let the chucking
power retention engage. Only than can the
tool itself be chucked by vigorously turning the sleeve in the "GRIP" direction (it
engages audibly with a grating noise.)
The chucking power retention is mainly needed for percussion drilling.
When the chuck is opened with a strong jerk as far as it will go, it is possible that it
can't be closed anymore. Instead, "grating" can be felt (as if the chuck were
over–tightened). In this case turn the sleeve once more in the "RELEASE"
direction; now it can be closed again. The chuck is not damaged by this "grating".
When percussion drilling in stone the drill bit should be checked for tight seat in the
chuck after first use. If necessary, re–tighten the chuck by hand.
Hold the grip and open the chuck by
turning the sleeve in the "RELEASE"
direction.
When turning the sleeve the chucking
power retention is released, after 1/4 turn
the clamping jaws open and release the
clamped tool.
