Foam pre-filter
4.
Inspect the foam pre-filter, and replace it if it is
damaged or excessively dirty.
5.
Inspect the paper air filter.
A.
If the paper air filter is damaged or is wet with oil
or fuel, replace it.
B.
If the paper air filter is dirty, tap it on a hard
surface several times or blow compressed air less
than 207 kPa (30 psi) through the side of the filter
that faces the engine.
Note:
Do not brush the dirt off the filter;
brushing forces dirt into the fibers.
6.
Remove dirt from the air-cleaner body and cover, using
a moist rag.
Do not wipe dirt into the air duct.
7.
Insert the foam pre-filter and the paper air filter into
the air cleaner.
8.
Install the cover.
Changing the Engine Oil
Service Interval:
After the first 5 hours
Yearly
1.
Move the machine to a level surface.
2.
Ensure that the fuel tank contains little or no fuel so
that fuel does not leak out when you tip the machine
onto its side.
3.
Run the engine for a few minutes before changing the
oil to warm it.
Note:
Warm oil flows better and carries more
contaminants.
4.
Disconnect the wire from the spark plug; refer
to Preparing for Maintenance (page 12).
5.
Place an oil-drain pan beside the machine on the side
nearest the oil-fill tube.
6.
Remove the dipstick from the oil-fill tube (Figure 26).
Figure 26
7.
Tip the machine onto its side, with the oil-fill tube
down, to drain the used oil out through the oil-fill tube
into the oil-drain pan (Figure 27).
Figure 27
8.
After draining the used oil, return the machine to the
operating position.
9.
Pour about 3/4 of the crankcase capacity of oil in the
crankcase.
Note:
Max. fill: 0.59 L (20 fl oz), type: SAE 30 or
10W-30 detergent oil with an API service classification
of SF, SG, SH, SJ, SL, or higher.
10.
Wait 3 minutes for the oil to settle.
11.
Wipe off the dipstick end with a clean cloth.
12.
Insert the dipstick into the oil-fill tube, but
do not
screw it in.
13.
Remove the dipstick and read the oil level on the
dipstick (Figure 28).
•
If the oil level is too low, slowly pour a small
amount of oil into the oil-fill tube, wait 3 minutes,
and then repeat steps 11 through 13 until the oil
level is correct.
•
If the oil level is too high, drain the excess oil until
the oil level is correct. To drain the excess oil, refer
to Changing the Engine Oil (page 13).
Important:
If the oil level in the crankcase is
too low or too high and you run the engine,
you may damage the engine.
