n Hot oil may cause burns. Allow engine to cool before
draining oil. Avoid prolonged or repeated skin exposure
with used oil. Thoroughly wash exposed areas with soap.
Use the following instructions to change the oil:
Clean area around oil drain cap.
Remove oil drain cap from the drain hose and dipstick to drain
oil completely into a suitable container.
When oil has completely drained, install oil drain cap and tighten
securely.
Place a suitable container beneath the oil filter and turn
filter counterclockwise to remove. Discard according to local
regulations.
Coat gasket of new filter with clean engine oil. Turn filter
clockwise until gasket contacts lightly with filter adapter. Then
tighten an additional 3/4 turn.
Fill engine with recommended oil and replace the dipstick. (See
“Before Starting the Generator” for oil recommendations).
Wipe up any spilled oil.
Dispose of used oil at a proper collection center.
3.3.6 REPLACING THE SPARK PLUG(S)
Use NGK BPR6HS spark plugs or equivalent. Replace the plugs
once each year. This will help the engine start easier and run
better.
1. Stop the engine and pull the spark plug wires off of the spark
plugs.
2. Clean the area around the spark plugs and remove them from
the cylinder heads.
3. Set the spark plug gaps to .76 mm (0.030 in.). Install the
correctly gapped spark plug into each cylinder head (Figure
12).
4. Push the boots firmly on the spark plugs.

3.4 SERVICE AIR CLEANER

The engine will not run properly and may be damaged if using a
dirty air cleaner. Clean or replace the air cleaner paper filter every
200 hours or once a year . Clean or replace more often if operating
under dusty conditions. To clean or replace paper air filter:
Remove air cleaner cover and remove paper filter (Figure 13).
Clean paper filter by tapping it gently on a solid surface. If the
filter is too dirty, replace it with a new one. Dispose of the old
filter properly.
Clean air cleaner cover. Next insert new paper filter into the base
of the air cleaner. Re-install air cleaner cover.
NOTE:
To order a new air filter, please contact the nearest authorized
service center at 1-888-GENERAC.

3.5 CLEAN SPARK ARRESTOR SCREEN

The engine exhaust muffler has a spark arrestor screen. Inspect
and clean the screen at least once each year (Figure 14). If unit is
used regularly, inspect and clean more often.
If using the generator on any forest-covered,
brush-covered or grass-covered unimproved
land, it must equipped with a spark arrestor.
The spark arrestor must be maintained in good
condition by the owner/operator.
