To change the safety cartridge after removing the primary ele-
ment, proceed as follows:

new one.
IMPORTANT
q
In case of doubts on the efficiency of the gasket, imme-
diately change it.
4 - Put back the air cleaner.
4.8.1.b TYRE ROTATION
WARNING
q
The tyres must not be inflated exceeding the recom-
mended pressure (see "5.1.3 TECHNICAL CHARACTE-
RISTICS").
q
Inflate all the tyres with the same pressure.
To avoid losing stability and manoeuvrability, always use the
machine with properly inflated tyres and avoid incorrect mano-
euvres that may shorten their life.
The manoeuvres to be avoided are the following:
1 - Excessive skidding when loading material.
2 - Abrupt steering, starting and stopping manoeuvres.
3 - Excessive use of counterrotations.
If excessive tyre wear is observed, it is advisable to exchange
the front wheels with the rear wheels immediately, so that the
wear gets uniform on the four wheels over time.
If two tyres are worn more than the others, change their posi-
tion keeping them on the same side, so that the rolling diame-
ter is the same on connected wheels.
When it is necessary to change two tyres, adopt the same pro-
cedure and eliminate the most worn ones, installing the new
ones on the same side.
IMPORTANT
q
Use only tyres recommended by the manufacturer.
