OPERATION IN MUD AND SNOW (Continued).
After each operation remove ice, snow, and mud from underneath trailer and from hoses, lines,
tubes, and electrical connections.
Return tire pressure to normal 115 psi (792.93 kPa) for the M870A3 after operation in mud.
Wash salt deposits from all equipment with fresh water.
Moist and salty areas can destroy the rust-preventative qualities of oils and greases. When
equipment is active, exposed surfaces should be cleaned and lubricated daily.
When equipment is inactive, unpainted parts should be coated with lubricating oil as specified in
the lubrication chart key (refer to Appendix I). All covers and caps should be in place.
Tires must be fully inflated 115 psi (792.93 kPs) when moving on rough or rocky terrain.
Underinflated tires will cause internal ruptures of tires and damage to tubes.
Before driving over stumps or rocks, make sure the trailer can clear them. Such objects can
damage components on the underside of the trailer. Beware of low hanging limbs that can damage
Be sure you have a serviceable spare tire and rim assembly because there is a greater than usual
chance of tire puncture.
