1 Check the rims.
• Check that the lock ring and lugs are installed correctly.
• Check that there are no cracks in the rims' parts.
In case of damage, the tyre and rim shall be dismantled and
checked.
Example: The figure shows inflation of drive wheel.
2 Check the air pressure in the tyres, see section Tyres, inflating
page 17 .
The pressure must be 1.0 MPa , inflate if necessary.
3 Check the tyres.
• Check for uneven and fast wear, this is caused by mechan-
ical problems such as, e.g., uneven brake action. Make sure
that such malfunctions are taken care of immediately.
• Remove penetrating objects such as crushed glass, pieces
of wood, metal filings, etc.
If the tyre is damaged, the wheel shall be dismantled and the
tyre shall be changed, see
Tyres, changing page 18 .
4 If the tyres and rims have no defects, check-tighten the wheel
nuts.
Tighten crosswise with torque, 400 Nm .
D A N GE R
Never stand directly opposite the tyre when deflat-
ing or inflating. The lock ring and lock lugs may re-
lease and shoot off when the pressure changes.
Do not release air through the valve if tyre or rim is
damaged. Drill holes in the tread to release the air.
If the tyre explodes, the force of the explosion
moves in the direction of the valve.
Do not exceed the prescribed air pressure. When
changing tyre or rim version, another air pressure
may apply. Contact Kalmar Industries.
