MQ Power DCA180SSI Generator Set

⚠ ALWAYS wear safety glasses when removing or installing force fitted parts.

Tools: Jack stands, Screwdriver or standard adjusting tool

1. Place the trailer on jack stands on secure level ground.
2. Check the wheel and drum for free rotation.
3. Remove the adjusting hole cover from the adjusting slot at bottom brake backing plate.
4. With a screwdriver or standard adjusting tool, rotate star wheel to expand brake shoes.
5. Adjust shoes outward until lining against drum makes wheel difficult to turn.
6. Rotate star wheel in opposite direction until wheel rotates freely with slight lining drag.
7. Replace the adjusting hole cover and lower trailer to the ground.
8. Repeat steps on remaining brakes.

⚠ NEVER place jumper plates on the voltage change-over board while generator is in operation.

1. Jumper the voltage change-over board for 240V operation.
2. Connect the load wires to the UVWO terminals.
3. Turn the voltage regulator knob clockwise to increase, counterclockwise to decrease voltage output.

⚠ ALWAYS make sure connections to the UVWO terminals are secure and tight; arcing could cause a fire.

1. Jumper the voltage change-over board for 480V operation using 6 jumper plates in 3 positions.
2. Every jumper plate must be used.
3. Connect the load wires to the UVWO terminals.

⚠ ALWAYS disconnect the negative terminal FIRST and reconnect negative terminal LAST.

⚠ Incorrect battery cable connection will cause electrical damage.

1. NEVER connect battery cables when MPEC Control Switch is in MANUAL position; set to OFF/RESET.
2. Place a small amount of battery terminal treatment compound around both terminals.
3. Red cable to positive terminal, black cable to negative terminal.

⚠ Allow engine to cool when flushing out radiator. Flushing while hot could cause serious burns from water or steam.

1. Open both cocks at crankcase side and lower radiator and drain coolant.
2. Open radiator cap while draining. Remove overflow tank and drain.
3. Check hoses for softening and kinks; check clamps for leakage.
4. Tighten both cocks and replace overflow tank.
5. Replace with coolant as recommended by engine manufacturer.
6. Close radiator cap tightly.
7. Flush radiator by running clean tap water until rust and dirt removed.

1. Drain the fuel tank completely; treat with fuel stabilizer if necessary.
2. Completely drain oil from crankcase and refill with fresh oil.
3. Clean entire generator, internal and external.
4. Cover the generating set and store in a clean, dry place.
5. Disconnect the battery.
6. Make sure engine coolant is at proper level.
7. If mounted on a trailer, jack trailer up and place on blocks.

⚠ Diesel fuel and its vapors are dangerous to health; avoid skin contact and inhaling fumes.

⚠ DO NOT OVERFILL fuel system; leave room for fuel expansion.

⚠ NEVER smoke around or near the generator.

1. Level tanks - make sure fuel cells are level with the ground.
2. Open cabinet doors on the right side of the generator.
3. Remove fuel cap and fill tank.
4. NEVER overfill fuel tank; read fuel gauge when filling.

⚠ DO NOT spill the fuel during disassembly.

1. Replace the fuel filter cartridge with new one every 500 hours or so.
2. Loosen the drain plug at the lower top of the fuel filter.
3. Drain fuel in fuel body together with the mixed water.
4. Vent any air.

1. Remove the old oil filter.
2. Apply a film of oil to the gasket on the new oil filter.
3. Install the new oil filter.
4. Run the engine for a while and check for leaks before adding more oil.
5. Clean excessive oil from engine.

⚠ NEVER manually start the engine with the main, GFCI or auxiliary circuit breakers in the ON (closed) position.

1. Place main, GFCI and aux. circuit breakers in OFF position.
2. Make sure voltage change-over board is configured for desired output voltage.
3. Connect load to receptacles or output terminal lugs.
4. Tighten terminal nuts securely to prevent load wires slipping out.
5. Close all engine enclosure doors.
6. Place engine speed switch in LOW (down) position.
7. Place MPEC control switch in MANUAL position to start engine.
8. Let engine run 1-2 minutes, then place engine speed switch in HIGH.

⚠ NEVER stop the engine suddenly except in an emergency.

1. Place MAIN, GFCI and LOAD circuit breakers to OFF position.
2. Place engine speed switch in LOW (down) position.
3. Let engine cool by running at low speed 3-5 minutes with no load.
4. Place MPEC Control Switch to OFF/RESET position.
5. Verify all status LEDs on MPEC display are OFF.
6. Remove all loads from generator.
7. Inspect generator for damage or loosening of components.
