SERVICE SAFETY
This unit uses high voltage circuits capable of causing serious injury or death. Only a qualified electrician
should troubleshoot or repair electrical problems occurring in this equipment.
• Before servicing, make sure the Engine Start switch is turned to OFF, circuit breakers are open (off)
and the negative terminal on the battery is disconnected. NEVER perform even routine service (oil/
filter changes, cleaning, etc.) unless all electrical components are shut down.
• NEVER allow water to accumulate around the base of the unit. If water is present, DO NOT service.
• NEVER service electrical components if clothing or skin is wet. If the unit is stored outside, check the
engine and generator for any moisture and dry the unit before use.
• NEVER wash the unit with a power washer or high pressure hose.
• Open the main circuit breaker before disconnecting battery cables.
• Keep all body parts, clothing, and other loose items away from moving parts on the unit.
• Wear heavy leather gloves when handling winch cables. Never let cables slip through bare hands.
• Make sure slings, chains, hooks, ramps, jacks, and other types of lifting devices are attached securely
and have enough weight-bearing capacity to lift or hold the unit safely. Always remain aware of the
position of other people around when lifting the unit.
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).
• Check tires on trailer for tread wear, inflation, and condition.
• NEVER tow trailer using defective parts. Inspect the hitch and coupling for wear or damage.
• Make sure the trailer hitch and the coupling are compatible. Make sure the coupling is securely fastened
to the vehicle.
• Connect safety chains in a crossing pattern under the tongue and ATTACH THE BREAKAWAY
CABLE TO THE REAR BUMPER OF THE TOWING VEHICLE. Do not attach the cable to the trailer
hitch.
• Make sure directional and brake lights on the trailer are connected and working properly.
• Check that all lug nuts holding wheels on are tight and none are missing.
• 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.
• When towing, maintain extra space between vehicles and avoid soft shoulders, curbs and sudden
lane changes. If you have not pulled a trailer before, practice turning, stopping, and backing up in an
area away from heavy traffic.
