SAFE USE AND OPERATION RULES 1. TOWING VEHICLE • • Make sure vehicle is capable of towing the load. Excess speed is the second most important cause of car-trailer accidents. Recommended maximum speed for all passenger cars towing trailers is 45 mph. 2. HITCH, BALL, COUPLER • • • Check that the hitch on the towing vehicle is capable of towing the trailer. The capability of the hitch is normally stamped on the hitch bar and the capacity of the ball is stamped on the ball.
5. LIGHTING • • • • • Check all lights before each use and every 100 miles. REPAIR OR REPLACE ANY BROKEN LENSES, BULBS OR REFLECTORS. Check wires for good connections and possible fraying or wearing of insulation. Bulbs supplied with this trailer are for 12 volt system. Bulbs used in tail lights are: Number -1157- Stop/Turn and Tail. Bulbs for running lights are: Number -1895. 6. TIRES • • • • Check tire for wear, damage and proper inflation before each use and every 100 miles.
8. MAINTENANCE • • • • • • Check and maintain the trailer, coupler, ball and hitch before each use and every 200 miles. Inspect coupler, hitch and ball for damage before each use. Ball or hitch can be damaged in parking, hitting curbs, dragging when crossing ditches or railroad tracks. Check safety chains and hooks for wear and do not allow safety chains to drag on ground.
