Installation
1. read all safety precautions listed.
2. on a level surface, chock the trailer wheels,
raise the trailer tongue at least 18" off the
ground with a floor jack or other suitable
lifting device, then use a jack stand to support
the trailer tongue.
3. identify a mounting location on one of the
trailer tongue's main frame rails that meets
the following requirements:
• is perpendicular to the ground (vertical)
• Provides adequate clearance when con-
necting the trailer to the tow hitch of the
towing vehicle.
• allows the jack to swing 90° and lock in
position when towing.
• Provides a clamping location for all four
bolts and both clamping brackets (see
Figures 2–3).
• Prevents the jack from twisting or sliding
during use.
