INFLATION PRESSURES
For safe and long-lasting tire use, the following
instructions must be closely observed.
• Use the correct pressures for each axle and for the type
of use planned.
• Ensure tire pressures are not lower than the correct val-
ues, to prevent overheating of the tires, which can lead
to:
- tire bursting;
- coming off rim;
- internal damage;
- irregular wear and short service life.
• Do not over-inflate the tires, as this may lead to damage
in the event of impact and, in extreme conditions, the
tire rim may be deformed or the tire may burst.
• Check tire pressures at least every two weeks, espe-
cially when liquid ballast is used. Tire pressures should
be checked only when the tires are cold, as pressures
rise during use, as a result of the tires heating up. Tires
can be assumed to be cold if they have not been used
for at least one hour, or have not covered more than two
to three kilometres. Never reduce tire pressures when
the tires are hot.
When checking tire pressures, keep the body away from
the valve mechanism or cap.
NOTICE: The tire pressures vary depending on the load
weighing on the axles.
WARNING
Explosion hazard!
Always maintain correct tire pressure as in-
dicated in this manual. DO NOT inflate tires
above the recommended pressure. Excessive
pressure could result in tire failure.
Failure to comply could result in death or se-
rious injury.
