3-18 HOT WEATHER OPERATION
3-18.1
Hot weather operation can cause ex-
pansion of parts, resulting in tightening of
bearings, fasteners, and moving parts. Fail-
ure of gaskets or seals can occur.
3-18.2
The trailer should be parked in the
shade if possible. Long exposure to the sun
will shorten service life of rubber components
(i.e., tires, light and hose grommets, hoses,
etc.) and paint life.
3-18.3
Check tire pressure early in the day be-
fore beginning operations while the tire is
cool. Put all valve stem caps back on after
checking.
3-18.4
If the area is extremely humid, protect
electrical terminals with ignition insulation
spray. Coat paint and bare metal surfaces
with an appropriate protective sealer.
3-18.5
For trailers with air brakes, the use of a
filter-lubricator in the towing vehicle’s air de-
livery system is recommended.
