Cleaning
CAUTION
Risk of injuries due to hot or sharp-edged drill bit.
Î
Wear safety gloves.
Î
Before carrying out any cleaning work on the
drill stand remove the drill bit and wet diamond
drill first.
The drill stand must be cleaned after each drilling
work session.
•
1
Rub down the toothing and the guide on
the drill stand column (20) carefully and use
compressed air to remove the drill dust; the
guide and toothing must
not
become smeared.
•
1
Clean the toothing of the pinion shaft (3).
•
1
Dismantle the pin of the tube lock (4) on the
pinion shaft (3) and pull the pinion shaft 3) out
of the spindle head (17). Rub down the toothing
of the pinion shaft (3) and use compressed air
to remove the drill dust. Push the pinion shaft
(3) back into the spindle head (17) up to the limit
stop.
•
3
Push the pin of the tube lock (1) through the
matching holes (2) and push until the clip is
snapped into position.
•
8
Clean and lightly grease the thread of the
tapered shaft (2). To do this, use an open-
ended spanner to unscrew the tapered shaft
(2). Pull out the tapered shaft (2) up to the limit
stop. Swing the machine collar (3) upwards and
remove from the spindle head (4) from above.
The thread of the tapered shaft (2) can now be
cleaned and greased. Re-install the tapered
shaft in the reverse order.
•
Ensure handles are dry and free from grease.
NOTE
Never use the feed crank handle to tighten the
tapered shaft; it could be damaged by excessive
torque.
Use an open-ended spanner only to tighten the
tapered shaft.

Maintenance
7.1 Setting guide clearance on the
spindle head
CAUTION
Risk of injuries due to hot or sharp-edged drill bit.
Î
Wear safety gloves.
Î
Before carrying out any cleaning work on the
drill stand remove the drill bit and wet diamond
drill first.
To achieve good drilling results and lengthen the life
of the drill stand, the guide clearance should be re-
adjusted after approx. 100 drilling operations. The
spindle head must move without any clearance. The
clearance is adjusted using two hexagon socket
head screws.
•
12
Release the clamping lever (1).
•
12
Undo both lock nuts (2).
•
12
Adjust both hexagon socket head screws (3)
until the clearance is removed.
•
12
Tighten both lock nuts (2).
•
12
Turn the capstan handle (4) in both
directions and check whether the spindle
head (4) moves without clearance.
NOTE
The clearance is set correctly if, when the clamping
lever is released, the spindle head with the
mounted diamond drill / drive unit does not move
downward under its own weight or if so, moves
very slowly.
