belt (Fig. 12 a/b): 280, 540, 780, 910, 1710, and 2500 rpm.
Tighten belt only lightly! A belt installed too tightly places
excessive loads on the motor and machine mechanical sys-
tem!
Important:
The belt cover must always be closed during operation.
1. Loosen knurled screw 4 (Fig.13) and open cover 7.
2. Loosen screw 5 using Allen key 1 by approx. 2 turns in
order to release belt pulley tension.
3. Place both belts in the desired position.
4. Press belt pulley 1 outwards with the belt tightener 8
below the gear wheels until the belt is tight. Tighten screw
5.
5. Should both belts be tensioned unevenly, the upper belt
may be tensioned separately. To do so, loosen screw 2 and
push motor 3 outwards until upper belt is tensioned.
6. Retighten screw 2.

Milling

Important!
Always wear protective goggles when milling. Always observe
the enclosed safety regulations.
1. Securely fasten the work piece using clamps, in a vice, or
to the support of the lathe chuck.
2. Alternatively, you can clamp the work piece in a machine
vice and mount the vice on the work table using the
T-grooves.
3. Adjust desired milling depth.
4. Tighten clamping screws 3 and 4 (Fig. 9).
5. Ensure that the milling tool does not touch the work piece.
6. Ensure that the proper spindle speed has been adjusted.
7. Switch on milling machine at switch 3 (Fig. 1).
8. Work using a suitable feed
When milling, always ensure that the feed is against the cut-
ting direction of the milling tool (Fig. 14).
Important!
Always provide feed by hand only! When using the milling
machine in conjunction with the lathe, feed action must not
occur via the lathe's automatic feed. Risk of injury!

Repair and maintenance

Important!
Disconnect mains plug prior to all repair and maintenance
work!

Belt replacement

If the belts are worn, you can replace these yourself. Replace-
ment belts are available from PROXXON Central Service
(address on reverse side of this manual).
1. Loosen screw 5 (Fig. 13) in order to release tension on pul-
ley 1.
2. Loosen the 3 screws 6 (Fig. 13) and lift off motor.

3. You can now remove the belts and replace them.
4. Assembly is in reverse order of removal.
Setting compound-type table guide play
If, after a time, the compound-type table guide is found to
have too much or too little play, the play can be reset using
the adjusting screws 2 (Fig. 15). For this purpose, loosen
adjustment screw lock nuts 1 and screw in all adjustment
screws evenly until play is eliminated. Retighten lock nuts
afterwards.

Setting compound-type table spindle play

If play of the spindles increases, release the nut 1 using a
socket spanner 2 (Fig. 16) approx. one half turn until play is
eliminated. Then turn the hand wheel to the right hand direc-
tion until the play has been eliminated. Now retighten the nut
1 firmly (lock).
See exploded view, page 48 Where necessary, play in the
individual spindle threads can also be achieved by slightly
tightening the spindle nut, Item 3, with the bolt, Item 25.

Machine lubrication

To ensure a long service life of your machine, please observe
the lubrication diagram in Fig. 17 (A: Lubricate each time
before use / B: Lubricate once a month). Only use acid-free
machine oil for lubrication.

After use

Disconnect milling machine mains plug before cleaning. Risk
of injury!
Clean compound-type table and milling machine using a soft
cloth and brush after use. Then lightly oil the guides and dis-
tribute the oil by moving the table. Never use compressed air
for cleaning the compound-type table as cuttings entering the
guides in this manner could destroy the guides.
Disposal:
Please do not dispose of the device in domestic waste! The
