OPERATION IN EXTREME HEAT
Do not park the semitrailer in sunlight for long periods of time because the effects of heat and sunlight shorten the life of
tires. If possible, shelter or cover semitrailer.

OPERATION IN EXTREME COLD
1.
Extreme cold can cause lubricants to thicken or congeal, insulation to crack and cause electrical short circuits,
and construction material to become hard, brittle, and easily damaged or broken.
Tires may freeze to the ground or have a flat spot if underinflated.
2.
Brakeshoes may freeze to the drums and need to be heated to prevent damage to mating surfaces.
