4.5.2 DH40G - Manual spindle sleeve feed with the spindle sleeve lever
ATTENTION!
The clutch of the fine feed has to be disengaged before the spindle sleeve lever can be
used. Activating the spindle sleeve lever when the fine feed is engaged may damage the
clutch.
Loosen the knurled screw (counter-clockwise). The sleeve lever moves away from the spin-
dle head and deactivates the coupler of the fine feed.
Check if the clamping lever of the quill is released.
Now it is possible to move the quill downward using the sleeve lever.

ATTENTION!
The higher the pre-set speed the more rapid is the feed speed on the sleeve. Make sure
to use the correct speeds depending on the used material and on the drill.

- 0.10 mm / turn
- 0.18 mm / turn
- 0.26 mm / turn
Turn the selector rotary switch to the position "ON" in order to activate the feed.
Adjust the drill depth stop by means of the ring of the hub. The drill depth stop can be
adjusted in a range from 0 to 90 mm. The advance is automatically switched off as soon as
the preset drill depth is attained and then it is returned to its home position by the resiliency
of the recuperating spring.
Check if the clamping lever of the quill is released.
Check that the clamping screw (knurled screw) of the quill lever is released. If the knurled
screw is not released it is not possible to activate the automatic sleeve feed.
Pull the sleeve lever outward. This way the sleeve feed is activated.
