Heater Use and Maintenance
The following points should be followed when operating a
unit equipped with a lower radiator hose heater.
IMPORTANT NOTE: Improper use of the lower radiator
hose heater could result in serious personal injury.
•
Verify that cooling system is full of a proper mixture
of water and engine coolant before each heater
use.
•
Heater is designed for all-night operation; how-
ever, 2-5 hours of heating just prior to starting is
usually sufficient for proper engine starting.
•
When heater is in operation, unit must be parked
in a level position to maintain the proper orientation
of the heater.
•
Use only an undamaged extension cord, outdoors
rated, three-prong grounded 120VAC cord with a
minimum amperage rating of 10A. Connect to
properly grounded 120VAC, GFCI outlet only.
•
Before starting the engine, unplug extension cord
from power first; then unplug heater cordset from
extension cord.
Trailer Wheel Bearings
The light tower is equipped with a grease zerk fitting to
allow lubrication of the wheel bearings without the need
to disassemble the axle hub. To lubricate the axle
bearings, remove the small rubber plug on the grease
cap, attach a standard grease gun fitting to the grease
zerk fitting and pump grease into the fitting until new
grease is visible around the nozzle of the grease gun.
Use only a high quality grease made specifically for
lubrication of wheel bearings. Wipe any excess grease
from the hub with a clean cloth and replace the rubber
plug when finished. The minimum recommended

Operation
lubrication is every 12 months or 12,000 miles (19,312
km); more frequent lubrication may be required under
extremely dusty or damp operating conditions.
Jack Maintenance
The following procedures should be performed at least
annually: For side-wind models, the internal gearing and
bushings of the jack must be kept lubricated.
•
Apply a small amount of automotive grease (A) to
the internal gearing by removing the jack cover, or
if equipped, use a needle nose applicator or
standard grease gun on the lubrication point found
on the side of the jack near the crank. Rotate the
jack handle to distribute the grease evenly.
•
A lightweight oil (B) must be applied to the handle
unit at both sides of the tube for side-wind models.
•
If equipped, the axle bolt and nut assembly of the
caster wheel must also be lubricated with the same
lightweight oil.
•
For top-wind models, apply a lightweight oil to the
screw stem.
