4-2 Operation MN2417 Figure 4-1 Trailer Component Identification Jack Coupler Coupler Handle Safety Chains Ball Coupler Jack Single or Double Axle Trailer Brake Safety Chains Trailer Pintle Engine Compartment Lift Hook Battery Compartment Tow Vehicle Mounted Pintle Hook Caution: Large “Engine Compartment Doors” on each side of enclosure must remain closed during operation. If doors remain open, engine will overheat due to insufficient air flow around engine. WARNING: If the trailer is not properly secured to the tow vehicles tow hitch, the trailer may separate from the tow vehicle and cause severe injury or property damage. Always ensure that the tow hitch and trailer tongue are properly connected, in good working condition and that safety chains are properly connected from the trailer to the tow vehicle. Safety Checks The following items should be checked before each use and once every 100 miles of towing: 1. Verify the tow vehicle is designed to tow the trailer before trailer is connected to the vehicles hitch. Using a tow vehicle that is too small is very dangerous. 2. Verify the stop, tail and turn signals are working properly. Replace damaged lenses, reflectors or bulbs. 3. Check wires for good connections and possible fraying or wearing of insulation. 4. Check and properly maintain the trailer, hitch, jack, ball and coupler. 5. Inspect hitch and ball for damage. Ball or hitch can be damaged in parking, hitting curbs, dragging when crossing ditches or railroad tracks. 6. Check and properly tighten all bolts on trailer, hitch, ball and coupler (including trailer wheels). 7. Check safety chains for wear and do not allow them to drag on ground or roadway. 8. Test breakaway system. Hydraulic surge brake system, normally have a cable or chain connected to the tow vehicle. In a break away condition, this cable or chain activates the master cylinder and operates the brakes as the trailer stops. An electric brake system, the emergency breakaway system has a battery, charger, breakaway switch with a pull pin and cable connected to the tow vehicle. In a break away condition, this cable operates the electric brakes (power provided by the brake battery) as the trailer stops. 9. Check all generator mounting hardware for tightness. 10. Check tow vehicle tires for wear and proper inflation. (Check vehicle’s owner manual for proper level of inflation of tires for towing a trailer). 11. Check trailer tires for wear and proper inflation. Replace only with a tire of the same size and capacity ratings. 12. Carry emergency flares, reflectors and fire extinguisher. 13. Carry spare light bulbs and fuses. 14. Wheel bearings should be checked and regreased after the first 100 miles, and every 4000 miles thereafter or at least once a year. Wheel bearing grease or a good grade of multi.purpose grease should be used for packing wheel bearings. If you don’t know how to repack your wheel bearing, take your trailer to a service shop. Be sure to properly tighten the axle nut and wheel nuts during assembly. 15. For proper tow vehicle maintenance while towing a trailer, check vehicle’s owner manual and manufacturer’s specifications. MN2417 Operation 4-3 Towing Instructions See Figure 4-1 for component identification. 1. Be sure the generator is off. 2. Shut all enclosure doors and latch the locks. 3. Back the tow vehicle to within a few inches of the trailer coupler (Pintle or Ball). 4. Be sure the Coupler Handle is in the “UP” (open) position or the Pintle Hook is Open. 5. Adjust the trailer jack for the height of the hitch on the tow vehicle. 6. Back the tow vehicle so the trailer coupler is directly over the tow vehicle ball hitch or the Pintle hook. 7. Lower the trailer so the trailer coupler rests securely on the ball hitch of the tow vehicle. Move the Coupler Handle to the horizontal position and lock it in place to securely hold the ball hitch of the tow vehicle. OR Latch the Pintle and lock the Pintle device securely. Note: If this is not done properly, the trailer may become unhitched when it is towed. 8. Retract the front jack, pull the jack pin and rotate the jack 90 degrees from vertical to the horizontal position, making sure the self.locking pin reseats and the jack is secured to the tow bar (stowed position). 9. Connect safety chains, making sure to cross them. If a safety chain is too long, simply twist it a few turns to shorten the chain before attaching to the tow vehicle. 10. Connect the trailer light connector to the tow vehicle. 11. Test the trailer lights to ensure they are operational. 12. Check tires for proper inflation. 13. Check wheel lug nuts for correct tightness (see Lug Nut Tightness). Wheel nuts/bolts should be torqued before the first road use and after each wheel removal. Check and re.torque after the first 50 miles and again at 100 miles. Check periodically thereafter. 14. Verify that all jacks, pins, cables, and doors are secured and trailer tongue is level. 15. Remove tire chocks (if used). These pr...
