Note:
Once the belt is properly tensioned (between motor axle and drill spindle),
you should be able to easily re-position
it by hand. When changing speed, it is not necessary to
re-tension the belt.
1. Unscrew knurled bolt
2
(Fig. 1) and remove cover hood
3
.
2. Rotate belt pulley while pressing belt in direction of smaller diameter
until belt has been released.
3. Position belt onto smaller diameter for desired speed.
4. Rotate other belt pulley, while pulling belt onto large diameter until seat-
ed properly for smooth function.
5. Install cover hood. Tighten knurled bolt

.
Adjusting belt tension
Caution!
Unplug drill before performing this operation!
Note:
When changing drill speed, it is not necessary to re-tension the belt.
Tension belt no tighter than necessary, i.e., tighten until there is no more
slack. An over-tensioned belt distends over longer periods of inactivity and
reduces motor output.
1. Unscrew knurled bolt
2
(Fig. 1) and remove cover hood
3
.
2. Loosen both bolts
1
(Fig. 3) by one rotation.
3. Using a screwdriver, lever out the motor to the rear
(Fig. 3) until the desired belt tension has been attained.
4. Tighten both bolts.
5. Install cover hood. Tighten knurled bolt
2
(Fig. 1).
Adjusting distance between bit and workpiece
In addition to using the centre sleeve lift (drill lift), you can set the TBH
bench drill to the desired height via a quick-adjustment crank mechanism
(70 mm). Adjusting the drill height does not displace the drill spindle centre
mark above the bench surface. In addition, the complete unit can be
moved to any position along the drill column.
Crank mechanism height adjustment:
1. Loosen knurled bolts
10
(Fig. 1).
2. Adjust extension arm to desired height using crank
12
.
3. Tighten knurled bolts.
Note:
Tighten knurled bolts to eliminate unnecessary stress on mechanism when
drilling
Re-positioning complete extension arm
Important!
Secure extension arm against falling.
1. Release knurled bolts
10
(Fig. 1) and knurled bolt
9
.
2. Move complete extension arm to desired position.
3. Re-tighten knurled bolts.
Utilising depth stop
Proceed as follows to adjust the max. drilling depth:
1. Loosen locking bolt
8
(Fig. 1).
2. Lower drill spindle until bit contacts workpiece.
3. Set desired drilling depth on dial
7
and re-tighten locking bolt.
Maintenance
Caution!
Unplug drill before performing any maintenance operations.
• Lubricate centre sleeve guide (Fig. 3) every 10 operating hours using a
few drops of machine oil.
• Following use, the drill must be thoroughly cleaned using a whisk or
brush to remove all swarf.
• All dirt deposits on the drill must be routinely removed using a rag.
• During longer periods of inactivity, the drive belt must be removed to pre-
vent deformation and erratic function.
• If, after it has been in use for a certain time, noises are heard on touching
the tailstock quill, this indicates play in the tailstock quill, which should
be taken up by slightly tightening the screw, 84 (see exploded
drawing, page 30).
Disposal
