HOSE INSPECTION

Inspect hoses for leaks regularly to ensure
efficient, economical and safe operation of the
engine and related equipment. Carefully inspect all
fittings, clamps and ties. To prevent chafing,
make sure hoses are not touching shafts,
couplings, heated surfaces, sharp edges or other
parts. Since hose clamps and ties can vibrate
loose or fail over time, frequently inspect and
tighten or replace as necessary.
Correct leaking hoses immediately. Failure to
correct leaks can cause severe damage to the
equipment, as well as increase operating costs
due to lost fluids. Treat fuel and oil leaks as an
immediate fire hazard.
WARNING
Personal injury and property damage may result
from fire caused by leaking flammable fluids.
Hose Service Life
Hoses have a limited service life. Thoroughly
inspect hoses annually. Look for surface damage
or indications of twisted, worn, crimped, cracked
or leaking lines.
immediately.
Hoses should be replaced during major overhaul or
after a maximum of seven service years. Be
certain replacement hoses are matching the
original equipment manufacturer's specifications.

LUBRICATION

Grease all lubrication points during scheduled
maintenance. For heavy loads or extended use,
lubricate more often. Refer to the Maintenance
Manual, section 24 for information on lubrication.

WHEELS AND TIRES VERIFICATIONS

Check for loose wheel nuts. Inspect all types of
rims for cracks. Cracks can appear in many
places but typically radiate out from where a load
is applied. Both aluminum alloy and steel wheel
nuts should be tightened to 450 to 500 foot-pounds
(610 to 680 N.m.) torque.
Keep the tires inflated to the recommended
inflation pressure to prolong tire life and for safety.
NOTE
For VIP vehicles, the cold tire inflation pressures
are found on the DOT certification plate located
under the L.H. console or behind the driver's
seat.
Do not exceed maximum inflation pressure.
Incorrect tire pressure increases tire wear and
could lead to loss of driving control because of
reduced road handling. Check tire pressure
regularly.
If replacement tires are different from those
specified on the certification plate, pressure must
be
