TABLE OF CONTENTS SAFETY TRAILER MOUNTING THREE POINT HITCH OPERATING FULL POWER CONNECTOR GROUNDING SHAFT INSTALLATION GEAR BOX MAINTENANCE MOUNTING Safety First While safety is built into every generator, imprudent operation, negligent maintenance or carelessness can contribute to present serious hazards to life and injury. Keep a fire extinguisher nearby. Know its proper use. Consult your local fire department for the correct extinguisher type.
placed on the trailer and connected with the shaft to the tractor and generator. IMPORTANT The generator MUST be mounted forward of the trailer axle to prevent the trailer from tipping backwards which can cause personal injury or death. Once the positioning of the generator, shaft and relationship to the axles has been determined, secure the generator using 4 hex bolts of at least 3/8 inch diameter with washers and nuts. Drilling four holes will be required.
or turn the generator main 2 pole contact. Use a heavy crimping tool to secure the wire into the contact. Insert the four contacts into the full power connector making certain that they are securely in place. Grounding Proper grounding will prevent an electric shock in the event loss of internal ground or loss of a ground in the load. The National Electric Code requires at least a number 12AWG stranded copper wire to the grounding lug on the generator.

Adjusting Voltage for PTO’s All PTO’s with 12 wire units feature an automatic voltage regulator that will maintain +/- 1 ½% voltage regulation. The voltage regulator is preset at the factory for the required voltage. If a change in voltage is required, the frequency meter MUST be connected to one line (hot) wire and to the neutral connection for the meter to function. On a three phase 240 volt series delta connection, there is no neutral.
