generator drive plate bolts in accordance with the
maintenance chart.

Jack Maintenance
The following procedures should be performed annually.
Side-Wind Models
•
The internal gearing and bushings of the jack must
be kept lubricated. Apply a small amount of
automotive grease 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 must be applied to the handle unit
at both sides of the tube.
• If equipped, the axle bolt and nut assembly of the
caster wheel must also be lubricated with the same
lightweight oil.
Top-Wind Models
•
Apply a lightweight oil to the screw stem.
Figure 4-1. Lubrication Points
Trailer Wheel Bearings
The trailer axles are equipped with a grease 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
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 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.
