2-24.
OPERATION IN EXTREME COLD
(continued).
e.
When parking for any period of time in temperatures below 0F (-180C), park in a sheltered area out of the wind
and clean off any buildup of ice or snow. Place a footing of planks or brush under tires to prevent them from
freezing to the ground. Make sure tires are properly inflated (para 1-10). Under-inflated tires will freeze, resulting
in flat spots.
f.
Use caution when placing semi-trailer in motion after a shutdown. Thickened lubricants may cause component
failure. Free frozen brakeshoes, or tires frozen to ground, with care.
2-25.
OPERATION IN EXTREME HEAT.
a.
Refer to Appendix E for proper lubrication during high heat conditions.
b.
Do not park semi-trailer in sunlight for long periods of time. Heat and sunlight shorten tire life.
CAUTION
DO NOT use gasoline or drycleaning solvent to remove oil or grease spots from tarpaulin. Use
only water and a scrubbing brush. Failure to follow this caution will damage the tarpaulin.
c.
Cover inactive semi-trailers with tarpaulins if no other shelter is available. Tarpaulins are subject to deterioration
from mildew and attacks by insects or animals. Shake out and air tarpaulins weekly for several hours. Clean
mildewed tarpaulins with a dry scrubbing brush. DO NOT clean with water until mildew is removed. If mildew is
found, examine tarpaulin to determine if it is rotted or weakened. Replace tarpaulin if damaged. If tarpaulin is not
damaged, treat as outlined in FM 10-16.
d.
Semi-trailers inactive for long periods in hot, humid weather are subject to rusting and the accumulation of fungi
growth. Frequently inspect, clean, and lubricate to prevent deterioration.
2-26.
OPERATION IN HIGH HUMIDITY AND SALTWATER AREAS.
a.
Dampness increases chances of corrosion. Inspect all surfaces and electrical connections for signs of corrosion.
Remove all signs of corrosion. Apply silicone compound (Item 2, Appendix D) to all electrical connections.
b.
Protect semi-trailer from direct rainfall whenever possible.
c.
Keep moisture from entering the fuel supply. Drain the filter separator sump (para 3-10) before each operation, to
remove accumulated moisture.
d.
Clean, inspect, and lubricate the semi-trailer frequently when operating in saltwater areas (refer to Appendix E).
