is not to exceed 10 mph (16 km/h) or less, depending on terrain.
JACK MAINTENANCE
The following procedures should be performed at least 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 light
weight oil.
TOP-WIND MODELS
• Apply a lightweight oil to the screw stem.
TRAILER WHEEL BEARINGS
The trailer axles are 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 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.
LOWER RADIATOR HOSE HEATER OPTION - USE AND MAINTENANCE
CAUTION
Improper use of the lower radiator hose heater could result in damage to the engine or
personal injury. Do not modify the location of the lower radiator hose heater.
The following points should be followed when operating a unit equipped with a lower radiator hose heater:
• Ensure cooling system is full of a proper mixture of water and engine coolant before each heater use.
• The heater is designed for all-night operation, however, 2-5 hours of heating just prior to starting is usually
sufficient for proper engine starting.
• When the heater is in operation, the unit must be parked in a level position to maintain the proper orientation
of the heater.
