Procedures
9Set or Replace Spark Plugs adjustment
⚠ Do not blast the spark plugs to clean.
Tools: Wire brush, Commercial solvent, Wire feeler gauge
- Clean the area around the base of the spark plugs to keep dirt and debris out of the engine.
- Remove the spark plugs and check the condition. Replace if worn or if reuse is questionable.
- Check the spark plug gap using a wire feeler gauge.
- Adjust the gap to 1.14 mm (0.045 inch) by carefully bending the ground electrode.
Preparing Genset for Start-up 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 that 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.
Battery Maintenance maintenance
⚠ DO NOT USE TAP WATER IN BATTERIES.
⚠ Storage batteries give off explosive hydrogen gas; no smoking, open flame or sparks near battery.
⚠ Battery electrolyte fluid is an extremely caustic sulfuric acid solution.
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 and, if necessary, fill with DISTILLED WATER ONLY.
- Have the state of charge and condition checked with an automotive-type battery hydrometer.
Battery Replacement maintenance
⚠ Be sure the AUTO/OFF/MANUAL switch is set to the OFF position before connecting the battery cables.
- Use the same number and type of battery: BCI Group No. 24F-6, 525 CCA @ 0 deg. F.
- The BCI number should be located directly on the battery.
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.
Tools: Suitable container, Clean, lint-free cloth
- Remove OIL DRAIN HOSE from its retaining clip.
- Loosen and remove OIL DRAIN HOSE CAP. Drain oil completely into suitable container.
- When all oil has drained, install and tighten OIL DRAIN HOSE CAP, and re-install into its retaining clip.
- Turn OIL FILTER counterclockwise and remove. Dispose of old filter.
- Apply light coating of new engine oil to seal of new oil filter. Install FILTER 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 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 oil level is below the dipstick ADD mark, remove oil fill cap and add recommended oil to bring level to FULL mark.
Engine Start-up and Transfer (Manual Transfer Switch) operation
⚠ Do not crank the engine continuously for longer than 30 seconds, or the 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 applicable instrument and gauge readings.
- Move the transfer switch manual handle to its STANDBY (GENERATOR) position.
- Set the generator's main line circuit breaker to its ON (or CLOSED) position.
Retransfer and Shutdown 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.
