Fuel Fired Coolant Heater Inspection
The heater requires no periodic maintenance other than a
visual inspection by a qualified technician preferably prior
to cold weather use. The technician can ensure that the
heater and all components are free from damage and in
proper working condition.
During the warmer months of the year when heating is not
required, the heater should be switched ON and allowed to
run for 5 to 10 minutes once a month at a minimum.
This will keep a clean, fresh supply of fuel in the heater
fuel system and keep all moving parts in top operating
condition.
Winch Inspection
Inspect the wire rope before and after each winching
operation. If the wire rope has become kinked or frayed, the
wire rope needs to be replaced. Be sure to also inspect the
winch hook and hook pin for signs of wear or damage,
and replace if necessary.
Inspect the remote control for damage, if equipped. Refer
to the WARN industries operator’s manual in the vehicle’s
glove compartment for additional inspection and
maintenance information.
For troubleshooting information refer to the 2003 LSSV
Military Trucks Service Manual Supplement.
