5.1 GENERAL INFORMATION

As it was designed, the machine does not need special
maintenance. Anyhow, in order to have the machine
work at its max. capacity and in order to constantly have
a perfectly efficient machine, some precautions must be
followed.
We here below list some operations of ordinary mainte-
nance. It is important to keep in mind that lower operating
cost and the utmost durability of the machine depend
on the procedure and constant compliance with these
rules.
For whatever problem or explanation, contact the area
dealer of the Manufacturer's technical department.
DANGER
The several maintenance and adjustment operations
shall be performed with the engine shut off and with
the machine well locked on a firm level ground.

5.2 ENGINE MAINTENANCE

As for the engine maintenance, make reference to the
specific engine instructions manual. Approximately, every
8 working hours: check and top the engine oil level up,
if necessary. Check, moreover, the engine air filter and
clean it if necessary.
Every 50 working hours, replace the engine oil.

5.3 MACHINE MAINTENANCE

Periodically wash the machine and clean thoroughly each
part. If a high pressure washing system is used, check that
the fuel does not get wet and that no part is damaged.
After each washing, it is necessary to lubricate all parts
subject to friction.
Replace the oil of the mechanical gearshift every 500
hours of use.
Only a specialized mechanics or dealer shall do this.

5.3.1 PRIMARY TRANSMISSION

The primary transmission is the belt transmission tran-
smitting motion to the mechanical gearshift (references
fig. 6).
In time the belt 1 adapts to the pulleys and it slightly sla-
ckens. In order to obtain a good transmission, the belt
shall have a load provided by spring 2 pulling the tensio-
ning unit/guide pulley 3.

Ordinary maintenance

This load is correct when the spring has a 6-7 mm flexu-
re.
Measure the length of the spring without any load and
press down the feed control lever (4 fig. 1); the spring
length shall increase by 6 – 7 mm. Now we get the exact
tension load on the belt. To correctly adjust the belt ten-
sion, act on the fastening screw 4.

5.3.2 PARKING BRAKE TRANSMISSION

The parking brake transmission is the transmission con-
trolling the braking force applied to the gearshift drum
(references fig. 7)
The gearshift brake is kept tightened by the spring 1 and
it is released only when the feed control lever is pressed
down (4 fig. 1). In case in time the machine does not stop
the crawlers sufficiently, tighten nut 2 to increase the load
of spring 1; afterwards, tighten with nut 4.

5.3.3 STEERING TRANSMISSION

If the transmissions of the crawler steering levers (6 & 7
fig. 1) have such a clearance that does not allow a good
crawler braking during the steering, there is a register on
the lever that may adjust this clearance. This operation
shall be performed only by a skilled person so as not to
compromise the machine operation.
If the transmissions are wrongly adjusted with the
consequent break of the gearshift components, the
manufacturer voids the warranty of the damaged
parts.
In case of any doubts or information, please contact
an authorized dealer.
The belt on the machine is a "special" belt; there-
fore we suggest using only original belts in case of
replacement.

5.3.4 CRAWLERS TENSIONING

To restore the tracks to their correct tension if they have
lengthened after many hours of service, unscrew the nuts
(2 fig. 6) and then tighten the track-tightening screws until
the right track tension has been obtained (they must be
