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 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 needing 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.
