- Evacuates sump directly to final containment via zero leak quick disconnect
- No spills, dripping filters, drain pans or intermediate containers needed
- Completes engine oil and filter change in less than 10 minutes
Trailer Wheel Bearing Lubrication maintenance
Tools: Grease gun
- Remove small rubber plug on grease cap
- Attach standard grease gun fitting to grease zerk fitting
- Pump grease until new grease is visible around gun nozzle
- Wipe excess grease from hub with clean cloth
- Replace rubber plug
Winch Preventive Maintenance maintenance
⚠ Replace cable immediately if damaged
⚠ Replace brake if slippage detected
- Check winch is free of dirt, oil, grease, water, and foreign substances
- Ensure all mounting bolts tightened to recommended torque values
- Check connections are securely tightened and free of corrosion
- Inspect cable for damage: cuts, knots, crushed or frayed portions, broken strands
- Check brake for slippage or drift by visual inspection when winch is under load
Raising the Mast operation
⚠ Do not extend mast beyond the colored mark on the second mast section
⚠ Stop immediately if the mast hangs up or winch cable develops slack
- Set up and level the unit
- Check both sets of mast cables for wear or damage; verify centered in pulleys
- Press and hold winch control toggle switch upward to telescope mast to desired height
- Rotate mast by loosening rotation knob, aim lights, then tighten knob
Shutting Down the Unit - Standard Controls operation
- Remove all loads from the outlets
- Switch individual circuit breakers for each light OFF (O)
- Switch the main circuit breaker OFF (O)
- Move the control power switch to STOP
Starting the Engine - Analog Controls operation
⚠ Do not continuously crank engine for more than ten seconds
⚠ Never start the engine with circuit breakers switched on
- Verify main circuit breaker and individual light breakers are OFF (O)
- Turn key to GLOW PLUG position, hold 10-15 seconds until glow plug indicator turns red
- Turn key to START position, hold until engine cranks and starts
- Release key; it moves to RUN position
- Allow engine to reach normal operating temperature before switching on loads
Towing the Unit operation
⚠ Maximum highway towing speed 55 mph (88.5 km/h); off-road 10 mph (16 km/h) or less
Tools: grease gun
- Raise rear jack and release locking pin into travel position
- Raise outrigger jacks and slide outriggers into frame until locking pins snap
- Use tongue jack to raise/lower trailer onto hitch; lock coupling and attach safety chains
- Lubricate grease fittings on leveling jacks
- Connect trailer wiring to tow vehicle and check lights
- Check wheel lugs; tighten in sequence to specification if removed
- Check tire inflation
Lowering the Mast Manually repair
⚠ Continuous use of this procedure could damage the planetary gear brake of the winch
Tools: 3/8 in. hex-wrench
- Remove power cables from the two terminals on the winch motor assembly
- Remove two flange head screws securing winch motor assembly, retain for reassembly
- Carefully remove the motor assembly, keeping the two pieces together
- Insert a 3/8 in. hex-wrench into the sleeve bearing
- Rotate the wrench counter-clockwise to lower the mast, stopping if slack develops
- Install the winch motor assembly and secure with screws once mast is fully down

Troubleshooting
6Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| Low oil pressure shutdown | Low oil level | Verify oil level on dipstick. Add oil, if needed. |
| Low oil pressure shutdown | Oil leaking from engine | Visually inspect the engine for leaks. |
| Low oil pressure shutdown | Oil pressure switch failure | Refer to OEM engine operator's manual to identify corrective action. |
| High coolant temperature shutdown | Low coolant level | Add coolant if needed. Allow engine to cool, then check coolant level in radiator. Restart engine and check coolant temperature. Stop engine immediately if coolant temperature is 210°F (99°C) or more. |
| High coolant temperature shutdown | Blockage in radiator | Inspect radiator shroud and ducting for blockage and remove any foreign matter. |
| High coolant temperature shutdown | Leakage in coolant hoses, engine block, or water pump | Inspect for visible leaks. Verify tension of water pump serpentine drive belt. Remove load on generator and restart engine. Verify coolant temperature and shut engine down immediately if it starts to overheat. Refer to the OEM engine operator's manual for additional information on engine overheating. |
