On failure of the compressed air release the valve
lever!
Too great a grinding pressure reduces the ma-
chine's performance and the service life of the grinding
belt.
If the contact arm is fitted with a grinding pad, it must be
installed as illustrated. The grinding belt then runs under
tension without exerting an additional load on the clamp-
ing spring (see 4.2). Belt slip is therefore avoided on the
drive roller.
The nonmetallic grinding pads are poor conductors of
grinding heat. Sustained grinding may then cause the belt
to detach from its adhesive bond. To prevent this, reduce
the load on the pad by lifting it at regular intervals.
Nonwoven belts must be operated at reduced speeds.

Without a tool clamped in check no-load
speed periodically and after each mainte-
nance. Even if the machine still operates
perfectly, the motor should be removed, cleaned and the
four slides checked for wear by a specialist after approx.
300 to 400 operating hours. The lubricant in the gear
head (Isoflex NBU 15) should be replaced at the same
time (do not wash out!).
