4-12 WINCHES (OPTION)
Inspect the winch cable before and after
every
usage. If frayed wires, nicks, kinks, worn spots,
breaks or any other sign of deterioration or dam-
age is found, immediate replacement is mandatory
before further usage. If the semitrailer is going to
be out in the weather for any length of time, it is
advisable to oil the winch cable to prevent untimely
rusting and deterioration of the cable. See
Table
for lubrication specifications.
Inspect the winch mechanism thoroughly each
week to insure safe, efficient operation.
WARNING
DO NOT HANDLE THE WINCH CABLE
WHEN THE WINCH IS IN THE ENGAGE
POSITION. HANDS OR CLOTHING
COULD GET CAUGHT IN THE CABLE
AND BE PULLED INTO THE SPOOL
CAUSING SERIOUS PERSONAL IN-
JURY.

The hydraulic engine package should be in-
spected weekly to insure continued proper opera-

Check the hydraulic oil level weekly, or
after any leakage. See
Table 4-1
for proper
hydraulic oil. With all hydraulic cylinders in
the retracted position and with the engine
stopped, check the hydraulic oil level.
4-13.2
Check hoses weekly for cracks or leaks.
If a valve or line leaks, it should be replaced
immediately.
4-13.3
Check the engine oil each time before
