Inspection
Figure: 150578-1
Check that the nuts of the front and rear wheels are
tightened well, using a torque wrench (with a torque
multiplier, if necessary).
Tapered nut Torque

10.14.3 - Tyres
ATTENTION
The diagrams notebook in the cab and the
"Technical data" chapter show the tyres available
for your vehicle model and the relative inflation
pressures.
ATTENTION
On receiving the vehicle check the air pressure of
the tyres.
• Check the tyre pressure regularly. The pressure
must be checked with cold tyres.
• The tyre pressure must always be at the levels
indicated.
• Check the size of the tyres installed and the
number of canvasses for the correct inflation
pressure.
DANGER
Tyres showing cuts or excessive wear must be
replaced immediately.
• At each use, check that the tyre shoulders are not
damaged.
• Keep oil, grease and corrosive liquids away from
the tyres to avoid deterioration of the rubber.
• To obtain the maximum efficiency do not use
tyres with more than 80% of tread wear.
WARNING
Inflating or operating on the tyres can be
dangerous.
To operate on tyres or install them, contact
specialised personnel.
In any case, to prevent serious or fatal injuries, follow
the safety precautions below.
• The vehicle wheels are very heavy. Handle with
care and make sure that, once stored, they can
not fall and injure someone.
• Never try to repair a tyre on a public road or
highway.
• Make sure the jack is placed on a solid and flat
surface.
• Make sure the jack is adequate for lifting the
vehicle.
• Use ratchet jacks or other locking means suitable
to support the vehicle during the tyres repair.
• Do not place any part of the body under the
vehicle.
• Do not start the engine while the vehicle is on the
jack.
• Never hit a tyre or a rim with a hammer.
• Make sure the rim is clean, without rust and
undamaged. Do not weld, solder, repair in any
way or use a damaged rim.
• Do not inflate a tyre unless the rim is mounted on
the vehicle or secured in such a way that it cannot
move in case the tyre or rim should break
suddenly.
• Do not inflate any tyre over the pressure
indicated by
DIECI
. If the bead chafer does not
settle on the rim, when arriving to this pressure
deflate the tyre and lubricate again with a
solution of soap and water, inflate again. Do not
use oil or grease. An inflation greater than
permitted with bead chafer not settled may break
the bead or rim with explosive force sufficient to
cause serious injury.
• After installing the wheel, tighten the nuts
between the wheel and the axles. Then check the
nut torque every day until the torque is stabilized.
