After extended operation in mud, sand, water or
similar dirty conditions, have your brakes
inspected and cleaned and drive axle joints
greased as soon as possible. This will prevent any
abrasive material from causing excessive wear.

Under frequent heavy duty operating conditions,
lubricate all grease fittings and inspect air cleaner
daily to prevent excessive wear.

permitted to maintain, repair, adjust or inspect the
vehicle.

equipment present in the work area. Do not use an
open flame to check level or leakage of fuel, battery
electrolyte or coolant. Do not use open pans of fuel
or flammable cleaning fluids for cleaning parts.
