Changing Engine Oil
Change oil after the first 20 hours of operation. Thereafter it should be
changed every 100 hours. This generator uses SAE 10W30 oil.
1. Drain oil by removing the drain plug and the oil filler cap while the
engine is warm.
2. Reinstall the drain plug and fill the engine with oil until it reaches the
upper level on the oil filler cap.
3. Dispose of used oil according to local zoning or environmental
regulations. Do not discard down a drain or into water.
Servicing The Air Cleaner
Maintaining the air cleaner in proper condition is very important. Dirt
induced through improperly installed, improperly serviced or inadequate
elements damages and wears out engines. Always keep the element clean.
Never run the generator without the air filter element.
To clean the air filter, fill a wash bucket or tub with warm water and a mild
soap such as dish soap. In order to get any residual dirt out after you've
used the foam cleaner, wash the filter in the soap and water solution,
rinse and repeat three times. This should clean out any remaining debris
and filter cleaner residue.
Cleaning and Gapping Spark Plug
If the plug is contaminated with carbon, remove the carbon using a plug
cleaner or wire brush. Use NGK BPR6ES or equivalent. (Note: the
1200PR uses BP7HS).
Adjust the electrode gap to 0.6 to 0.7 mm (0.024 to 0.028 in).
Cleaning Fuel Strainer
Dirt in the fuel is removed by the fuel strainer.
1. Remove the strainer cup and throw away water and dirt.
2. Clean the screen and strainer cup with gasoline.
3. Insert the cup into the main body, making sure to avoid fuel leak.
Periodic Operation and Inspection:
When using the generator as emergency electric power source, periodic
operation and inspection are needed.
Fuel (gasoline) and engine oil will deteriorate with time, and cause the
engine to be difficult to start and result in improper engine operation and /
or failure.
