PNEUMATIC TIRES
Changing tires or adding air can be a hazardous
business. Special tools and procedures are
required for changing off-highway tires.
Explosion and separation of a tire and/or rim parts
can cause serious injury or death. (FIG. 44) Always
follow the manufacturer's recommendations or
see your tire supplier.

PERFORM MAINTENANCE SAFELY
ROPS (Roll-Over Protective Structures)
Periodically inspect ROPS for cracks and loose mounting
hardware.
Replace all missing, deteriorated or worn rubber parts.
If it becomes necessary to remove a ROPS, reinstall it only
on the same machine, in its original position. (FIG. 46)
NEVER alter the ROPS in any way without the written
approval of the manufacturer.
NEVER cut holes in or weld on ROPS without the
manufacturer's approval.
NEVER attempt to repair a damaged ROPS – it must be
replaced with a new unit, approved for that machine.
Periodically inspect seat belts for wear, tear, deterioration
or excessive dirt. Replace them if necessary.
AIR CONDITIONERS
NEVER attempt to weld on or near air conditioners.
Poisonous gas may be formed when refrigerant gas is
exposed to a flame or excessive heat.
Maintenance and repair of air conditioners ... except for
very minor repairs or servicing ... must be done only by
an experienced air conditioner or refrigeration technician.
(FIG. 47)

TIRE PRESSURE
Check tire pressure before starting operation.
An air pressure rise during operation is normal
and should NOT be reduced. Overloads or over-
speeds may produce increased tire pressures due
to heat. Never bleed tires. Reduce your load – or
speed – or stop until tires cool.
ADD AIR
From a distance – with air chuck clipped on the
tire valve – and with extension hose that permits
you to stand behind tread. (FIG. 45) Always use a
tire cage or equivalent for protection.
