Inspection, Maintenance and Adjustment
TIRES
Inflating Tires
Recommended tire pressures should normally be followed.
Special operations may justify a different pressure. In such
cases, follow the instructions from the tire manufacturer and
do not exceed the maximum permissible pressures,
(See
page 4-87)
The tire pressure may have been raised before the machine
was delivered from the factory. Therefore, check and adjust
the tire pressure according to recommendations, before
putting the machine to work for the first time.
• When checking the air pressure, the tire must be
cold and the machine not have a load.
• Ask all other persons to leave the danger area (in
front of the rim).
• Stand by the tire tread as shown in the figure.
Tire installed on a split rim may explode causing
injury or in the worst case death.
• Use a long air hose (with a self attaching air
chuck) which allows you to stand outside the
danger area.
• Tires on stored wheels (spare wheels) must be
kept laying down on their side, and only be
inflated sufficiently to keep the rim parts in
position.
Wheel Nut, Tightening Check
After having changed a tire or if the wheel has been
removed and installed for any other reason, the wheel bolts
must be check for tightness after eight hours of operation.
Tighten wheel nuts to 58 - 62 kg•m (420 - 448 ft lb).
WARNING!
Repair work on tires and rims must be carried out by
persons who have been especially trained for this.
The instructions stated below apply to an inflated tire
where the pressure needs to be increased. If the tire
has lost all pressure, a trained service engineer must be
called in.
