2. Fuel and oil requirements
Fuel: Only use unleaded gasoline, ethanol content ≤ 10%, octane rating ≥ 87; Stop the machine for cooling before refueling, ensure that the oil level does not exceed the neck of the filling port, and check for leaks after refueling.
Engine oil: The new engine has no engine oil, and 10W30 engine oil must be added before the first start-up (5W30 in winter and SAE30 in summer); Check the liquid level of the refrigeration unit, which should be between the H (high) and L (low) marks on the dipstick.
3. Startup method
Startup method, operating steps, applicable models, precautions
Electric start 1. Confirm that the engine oil is sufficient and the battery is connected; 2. Reset the circuit breaker; 3. Turn the fuel valve to ON; 4. Press the switch to START and release it after starting (automatic return to RUN). Both options are applicable. If it does not start for 5 seconds, release it and retry after 15 seconds; Charging when the battery is depleted
Backlash start 1. Same as 1-3 above; 2. Slowly pull the rope until the resistance increases, and quickly pull it upwards away from the generator. When only the WPro8500 battery runs out of power/disconnects, manually turn on the choke and turn it off after starting
Remote start 1. Turn the switch to RUN; 2. Long press the REMOTE PAIRING button on the panel for 3 seconds; 3. Long press the STOP button on the remote control until the indicator light flashes, and then long press the START button until it flashes; 4. Press and hold the PAIRING key for 3 seconds to complete pairing; 5. Press the START button on the remote control to start both models, with an effective distance of ≤ 100 feet (affected by battery level). After starting, there will be a 15 second delay in output
4. Stop method
Normal stop: 1 Disconnect all loads; 2. Cooling during no-load operation; 3. Turn the switch to OFF; 4. Close the fuel valve (allow the carburetor to run out of fuel during long-term storage).
Emergency stop: Simply turn the engine control switch to OFF.

Special maintenance operation
Oil change: When the engine is in a cold state, drain the oil from the oil pan through the oil drain plug, remove the plug and drain, then reinstall and add oil to the standard level.
Air filter cleaning: Remove the cover and take out the filter cotton, clean with household detergent and warm water, squeeze and drain (do not twist), air dry, apply a thin layer of cleaning oil, and reinstall according to the "fine filter (ash) inside, coarse filter (black) outside".
Spark plug maintenance: Remove the spark plug with a spark socket wrench, check the insulation layer for cracks and a gap of 0.027-0.032 inches (0.60-0.80mm), clean and reinstall it; Recommended replacement models: AC Delco 4EXLS, Autolite 52, Champion N9YC, Bosch W7DC, Torch F7TC.
Battery maintenance: Start the generator every 2-3 months and charge it for 15 minutes, or connect the charger to the charging port (RUN mode) for charging; The replacement model is as follows:
Model Westinghouse Part Number Compatible Battery Model Voltage (V) Capacity (Ah) Size (inches)
WPro8500 100557 YT9A 12 9 5 5/16 × 3 × 5 3/8
WPro12000 100639 YT51913-22 12 20 7 1/8 × 3 × 6 9/16
Troubleshooting
Possible causes and solutions for the problem
The engine is running but there is no power output. 1. The circuit breaker has tripped; 2. The power plug is not securely plugged in; 3. Power cord malfunction; 4. Electrical equipment malfunction; 5. GFCI trips; 6. Internal equipment malfunction: 1. Reset the circuit breaker and check for overload; 2. Re plug (the 240V plug needs to be turned clockwise by 1/4 turn); 3. Replace the power cord; 4. Connect to normal equipment testing; 5. Reset the GFCI circuit breaker; 6. Send to authorized service points
The engine cannot start/stalls after starting. 1. The fuel valve is closed; 2. Lack of gasoline; 3. Fuel pipeline blockage; 4. The startup battery runs out of power; 5. The air filter is dirty; 6. Low oil level (low oil protection); 7. Spark plug not tightened/faulty; 8. Fuel deterioration: 1. Open the fuel valve; 2. Add gasoline that meets the requirements; 3. Check and clean the fuel passage; 4. Charging (electric start only); 5. Clean/replace the air filter; 6. Add engine oil to the standard level; 7. Tighten/replace spark plugs; 8. Drain the deteriorated fuel and add new fuel
Remote start failure: 1. The remote control battery is dead; 2. Exceeding the remote control distance (>100 feet); 3. The remote control is not paired with the generator. 1. Replace the remote control battery; 2. Close to the generator (≤ 100 feet); 3. Follow the pairing process again
Sudden shutdown of generator: 1. Lack of fuel; 2. Low oil level (protective shutdown); 3. Excessive load; 4. Internal equipment malfunction: 1. Add gasoline; 2. Add engine oil; 3. Reduce load after restart; 4. Send to authorized service points
