6.1. ROUTINE TECHNICAL MAINTENANCE

Regularly check the condition of knives. Each drum should be equipped with three new or
uniformly worn CMA 120 knives. A suitable wrench is provided for replacing the knives
(Fig. 8.). Correctly settled knife should easily spin on the knife-holder pin. Fig. 8. shows how
to replace the cutting knives.

Systematically check the condition of transport strips. If they are worn to such a degree that
the drum can untimely wear out, replace strips with new ones.

During the season check the functioning of the lock every day (pos. 4. Fig. 5.). If the
mechanism functions while mowing, even though no obstacle has been struck, this means
that the force of the spring is too small and it should be tighten better with a securing nut
(pos. 5. Fig. 5.).

During the first few hours of work carefully watch the behaviour of V-belts, after 0,5 –
4 hours of work under full load – tighten belts. The ‘x’ clearance (Fig. 5) should be
approximately 1 mm. This clearance is adjusted with nuts 6. and 7. Proceeding like this
the initial stretch is considered. After next 24 hours of work check the indicator again
and tighten belts if necessary. Maximum ‘x‘ clearance cannot exceed 3 mm.
Next inspections can be done even after few hundred hours of work.
Notice: If the V-belts are stressed more than the indicator is showing, a damage to ball
bearings can be caused in result of overloading.

After a few working hours of a new or repaired machine check if all the bolts and nuts are
properly tightened, especially the bolts tightening the lift. Repeat the checking in regular
intervals.

If the gasket between the shield and main frame (for example after repairing the machine)
needs to be replaced, use only original gaskets. Stick them on exactly in place of the old one.
Bolts that connect shield with main frame should be tighten with torque 48 Nm.
