nuts. Always use a lockwasher and place washer next to nut. Unless otherwise specified by ball manufacturer

down for proper height. The holes are 1.50" apart. Hitch bar may be used either up or down.

DO NOT TOW MULTIPLE TRAILERS: Do not attempt to tow any type of trailer behind another trailer. Towing
multiple trailers may cause severe instability, loss of control and/or structural failure, and may result in vehicle
accident, property damage and personal injury. Towing multiple trailers is illegal in many jurisdictions.
TOWING TIPS
DRIVING: Good habits for normal driving need extra emphasis when towing. The additional weight affects
acceleration and braking, and extra time should be allowed for passing, stopping, and changing lanes. Signal
well in advance of a maneuver to let other drivers know your intentions. Severe bumps and badly undulating
roads can damage your towing vehicle, hitch, and trailer, and should be negotiated at a slow steady speed. IF
ANY PART OF YOUR TOWING SYSTEM "BOTTOMS" OUT, OR IF YOU SUSPECT DAMAGE MAY HAVE
OCCURED IN ANY OTHER WAY, PULL OVER AND MAKE A THOROUGH INSPECTION. CORRECT ANY
PROBLEMS BEFORE RESUMING TRAVEL.
CHECK YOUR EQUIPMENT: Periodically check the condition of all your towing equipment and keep it in top
condition.
TRAILER LOADING: Proper trailer loading is important. Heavy items should be placed close to the floor near
the trailer axle.
The load should be balanced side-to-side and firmly secured to prevent shifting. Tongue weight should be about
10-15 percent of the gross trailer weight for most trailers. Too low a percentage of tongue weight will often
produce a tendency to sway.
TIRE INFLATION: Unless specified otherwise by the towing vehicle or trailer manufacturer, tires should be
inflated to their maximum recommended pressure.
TOWING VEHICLE AND TRAILER MANUFACTURERS' RECOMMENDATIONS: Review the owners' manuals
for your towing vehicle and trailer for specific recommendations, capacities, and requirements.
PASSENGERS IN TRAILERS: Trailers should NOT be occupied while being towed, under any circumstances.
TRAILER LIGHTS, TURN SIGNALS, AND ELECTRIC BRAKES: Always hook up trailer lights, turn signals,
electric brakes and break-away switch connection (if so equipped) even for short trips.
REMOVE HITCH WHEN NOT TOWING: Remove hitch from towing vehicle receiver when not towing, to reduce
chance of striking hitch on driveway ramps or other objects, and minimize damage in the event of a rear-end
collision.
