TOWING THE UNIT

1. Use the jack to raise or lower the trailer onto the hitch of the towing vehicle. Lock the hitch coupling and attach

the safety chains or cables to the vehicle. Raise the jack foot completely.

2. Connect any trailer wiring to the tow vehicle. Check for proper operation of the directional and brake lights.

3. Make sure all doors are properly latched.

4. Check for proper inflation of the trailer tires. For maximum tire pressures, refer to “Specifications” on page 7.

5. Check the wheel lugs. Tighten or replace any that are loose or missing. If a

tire has been removed for axle service or replaced, tighten the lugs in the

order shown to the following specifications:

a. Start all lug nuts by hand.

b. First pass tighten to 20-25 ft-lbs (27-33 Nm).

c. Second pass tighten to 50-60 ft-lbs (67-81 Nm).

d. Third pass tighten to 90-120 ft-lbs (122-162 Nm).

Note: After the first road use, re-torque the lug nuts in sequence.

6. Maximum recommended speed for highway towing is 45 mph (72 km/h). Recommended off-road towing

speed is not to exceed 10 mph (16 km/h) or less, depending on terrain.

TRAILER WHEEL BEARINGS

Some trailers 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.
