⚠ Perform at least annually.

Tools: grease gun, needle nose applicator

1. Apply a small amount of automotive grease to the internal gearing (jack cover or grease point).
2. Rotate the jack handle to distribute the grease evenly.
3. Apply lightweight oil to the handle unit at both sides of the tube (side-wind).
4. Lubricate the axle bolt and caster wheel nut assembly with lightweight oil.
5. For top-wind models, apply lightweight oil to the screw stem.

⚠ 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.

1. Ensure the cooling system is full of the proper mixture of water and engine coolant before each heater use.
2. The heater is designed for all-night operation; 2-5 hours of heating prior to starting is usually sufficient.
3. Ensure the unit is level to maintain proper orientation of the heater while in operation.
4. Use only an undamaged, outdoor rated, three-prong grounded 120VAC extension cord with a minimum 10A rating.
5. Before starting the engine, unplug the extension cord from the power first, then unplug the heater cordset.

⚠ Do not use this procedure unless absolutely necessary. Continuous use could damage the planetary gear brake of the winch. This procedure will not work if the planetary gear brake is damaged.

Tools: 3/8 inch allen head wrench

1. Remove the power cables from the two terminals on the winch motor assembly.
2. Remove the two flange head screws securing the winch motor assembly to the winch; retain the screws.
3. Carefully remove the motor assembly, making sure the two pieces do not separate.
4. Insert a 3/8 inch allen head wrench into the sleeve bearing.
5. Rotate the wrench counter-clockwise to lower the mast; if slack is observed stop immediately and remove the slack.
6. When the mast is completely down, reinstall the winch motor assembly with the retained screws.

⚠ Do not perform routine service unless all electrical components are shut down.

1. Verify the key switch is in the OFF position.
2. Verify the circuit breakers are switched OFF (O).
3. Disconnect the negative (-) terminal on the battery.
