Failure to follow the safety guidelines described below could result in severe injury or death. Read and follow all safety warnings described in the engine operator's manual. A copy of this manual was supplied with the unit when it was shipped from the factory. • DO NOT run engine indoors or in an area with poor ventilation.
TOWING SAFETY Towing a trailer requires care. Both the trailer and vehicle must be in good condition and securely fastened to each other to reduce the possibility of an accident. Some states require that large trailers be registered and licensed. Contact your local Department of Transportation office to check on license requirements for your particular unit. • Check that the hitch and coupling on the towing vehicle are rated equal to, or greater than, the trailer's Gross Vehicle Weight Rating (GVWR).

EMERGENCY STOP SWITCH: For emergency shutdown; stops engine and trips main circuit breaker. 3. CONTROL PANEL LOCATION (under door): Refer to page 9. 4. GROUND STUD: For grounding generator and equipment connected to the unit. 5. SAFETY CHAINS: Used in a crossing pattern under the tongue to attach unit to towing vehicle. 6. TONGUE JACK: Used to level generator before starting.
GENERATOR START UP Before starting the generator, carefully read the prestart checklist. Make sure that all of the items are checked before trying to start the generator. This check list applies for both manual and remote starting of the generator. PRESTART CHECKLIST Make sure the engine start switch is in the “OFF/O” position. Make sure the circuit breakers (main and equipment) are switched “OFF/O”.
WET STACKING The unit is powered by a diesel engine. Diesel engines are susceptible to wet stacking if lightly loaded. Wet stacking occurs when an engine is run at less than 30% of its full load capacity, causing unburned fuel to accumulate in the exhaust system. Wet stacking can be detected by continuous black exhaust when the unit is under a constant load. It can also cause fouling of injectors and buildup on engine valves.
Always switch all circuit breakers to the “OFF/O” position to prevent starting the generator under load. Note: For extended storage time, disconnect the battery. Refer to the engine operator’s manual for extended storage requirements. LIFTING THE TRAILER 1. Make sure the equipment being used to lift the generator has sufficient capacity. Refer to “Specifications” on page 8 for approximate weights. 2. Always remain aware of the position of other people and objects around you as you move the unit. 3.
6. Maximum recommended speed for highway towing is 45 mph (72 km/h). Recommended off-road towing speed is not to exceed 10 mph (16 km/h) or less, depending on terrain. JACK MAINTENANCE The following procedures should be performed at least annually. SIDE-WIND MODELS • • • The internal gearing and bushings of the jack must be kept lubricated.
• Use only an undamaged, outdoors rated, three-prong grounded 120VAC extension cord with a minimum amperage rating of 10A. Connect to a properly grounded 120VAC, GFCI receptacle only. • Unplug the extension cord from power first; then unplug the heater cordset from the extension cord before starting the engine. GENERAL MAINTENANCE Poorly maintained equipment can become a safety hazard.
BASIC MAINTENANCE SCHEDULE - KUBOTA ENGINE Refer to the original equipment manufacturer’s operating manual for a complete list of maintenance requirements. Failure to comply with the procedures as described in the engine operator manual will nullify the warranty, decrease performance and cause equipment damage or premature equipment failure. Maintenance records may be required to complete a warranty request. Use the schedule in the following table as a guide for regular maintenance intervals.
