TOWING THE TRAILER
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. Release the jack locking pin and rotate the jack into the
travel position. Make sure the locking pin snaps into place.
2.
Connect any trailer wiring to the tow vehicle. Check for proper operation of the stop and signal lights.
3.
Make sure all doors are closed and secure.
4.
Check for proper inflation of the trailer tires. Maximum tire pressures can be found on pages 9-12.
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).
After the first road use, re-torque the lug nuts in sequence.
6.
Maximum recommended speed for highway towing is 45 m.p.h. Recommended off-road towing speed is not
to exceed 10 m.p.h. or less depending on terrain.
TRAILER WHEEL BEARINGS
Some trailers may be 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; more frequent lubrication
may be required under extremely dusty or damp operating conditions.
