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
4-86)
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 85 kg•m (615 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.
