Procedures
9Reconfiguring the Fuel System (NG to LP) adjustment
⚠ Serious injury or damage may occur if not configured properly. Please consult an Authorized Dealer with any questions.
- Turn the main gas supply off.
- Remove the carburetor fuel hose from the outlet port (Port 1) of the demand regulator.
- Remove the brass hose fitting from the outlet port (Port 1).
- Remove pipe plug from Port 2.
- Install brass hose fitting into Port 2.
- Install pipe plug into Port 1.
- Connect carburetor gas hose to brass fitting.
- Tighten all clamps and plugs.
- Make sure fuel supply is of the proper pressure and type for configuration.
- Reverse the procedure to convert back to natural gas.
- Set the Dip switch inside the control panel to LP or NG position when switching fuels.
Preparation for Start-up (Start-up Checklist) installation
⚠ Before working on the generator, ensure the AUTO/OFF/MANUAL switch is in the OFF position and the 120VAC supply to the battery charger is switched OFF.
Tools: Manometer
- Ensure the 120VAC circuit breaker to the battery charger is open.
- Remove the fuse from the control panel (15 Amp ATO fuse).
- Connect the battery cables to the battery. Attach negative battery cable last.
- Close the 120VAC circuit breaker to the battery charger.
- Measure the voltage at the battery before and after the charger is turned on.
- Verify all AC electrical connections are tight at the circuit breaker and transfer switch.
- Check all hoses, clamps and fittings for leaks or damage.
- Open the valve to the engine fuel line and bleed the fuel system of air.
- Open the generator main line circuit breaker.
- Connect a manometer to the gas line and record the static pressure.
- Insert the fuse into the control panel.
- Move the AUTO/OFF/MANUAL switch to the MANUAL position; the engine should crank and start.
Battery Maintenance maintenance
⚠ Do not use tap water in batteries. Storage batteries give off explosive hydrogen gas.
⚠ Battery electrolyte fluid is an extremely corrosive sulfuric acid solution that can cause severe burns.
Tools: Automotive-type battery hydrometer
- Inspect the battery posts and cables for tightness and corrosion. Tighten and clean as necessary.
- Check the battery fluid level of unsealed batteries; if necessary fill with DISTILLED WATER ONLY.
- Have the state of charge and condition checked with an automotive-type battery hydrometer.
Changing Engine Oil maintenance
⚠ After refilling the crankcase with oil, always check oil level on dipstick. NEVER OPERATE ENGINE WITH OIL BELOW THE DIPSTICK ADD MARK.
- Warm up the engine, shut it down and drain immediately.
- Remove OIL DRAIN HOSE from its retaining clip.
- Loosen and remove OIL DRAIN HOSE CAP. Drain oil completely into suitable container.
- Install and tighten OIL DRAIN HOSE CAP, and re-install into its retaining clip.
- Turn OIL FILTER counterclockwise and remove. Properly dispose of old filter.
- Apply light coating of new engine oil to seal of new oil filter. Install and tighten by hand only.
- Remove OIL FILL CAP. Add recommended oil. Do not fill above the dipstick FULL mark.
- Start engine and check for oil leaks.
Changing the Engine Air Cleaner maintenance
- Remove the air cleaner cover.
- Replace the air filter (part number 059402) making sure it is positioned properly.
- Reattach the cover.
Check Engine Oil Level maintenance
⚠ Do not fill above the FULL mark.
Tools: Clean, lint-free cloth
- Remove oil dipstick and wipe dry with a clean, lint-free cloth.
- Install oil dipstick, then remove again.
- Oil should be between FULL and ADD marks.
- If below the ADD mark, remove oil fill cap and add recommended oil to the FULL mark. Do not fill above the FULL mark.
Setting the Spark Plug Gap maintenance
⚠ Do not blast the spark plugs to clean.
Tools: Wire feeler gauge, Wire brush
- Clean the area around the base of the spark plugs to keep dirt out of the engine.
- Remove the spark plugs and check the condition; replace if worn or reuse is questionable.
- Check the spark plug gap using a wire feeler gauge.
- Adjust the gap to 0.5-0.6 mm (0.020-0.025 inch) by carefully bending the ground electrode.
Engine Start-up and Transfer (Manual Transfer Switch) operation
⚠ Do not crank the engine continuously for longer than 30 seconds, or heat may damage the starter motor.
⚠ Do not attempt manual operation until all power supplies to the transfer switch have been positively turned off.
- Turn OFF or disconnect the utility power circuit to the transfer switch.
- Set the transfer handle to its UTILITY (NORMAL) position with load circuits connected to utility.
- Set the standby generator's main line circuit breaker to its OFF (or OPEN) position.
- Start the generator.
- Let engine stabilize and warm up; check all instrument and gauge readings.
- Move the transfer switch manual handle to its STANDBY (GENERATOR) position.
- Set the standby generator's main line circuit breaker to its ON (or CLOSED) position.
Retransfer and Shutdown (Manual Transfer Switch) operation
- Set the standby generator's main line circuit breaker to its OFF (or OPEN) position.
- Manually move the transfer switch handle to its UTILITY (NORMAL) position.
- Turn ON the utility power supply to the transfer switch.
- Let the generator run at no-load for a few minutes to stabilize internal temperatures.
- Shut down the generator.
