3. Remove the air filter (Figure 40).
Figure 40
4. If the air filter is damaged or is wet with oil or fuel,
replace it.
5. If the air filter is dirty, tap it on a hard surface several
times or blow compressed air less than 30 psi (207
kPa) 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. Install the filter into the air cleaner.
8. Close the cover.
Changing the Engine Oil
Service Interval:
After the first 5 hours
Yearly
Change the engine oil after the first 5 operating
hours
; change it yearly thereafter.
Run the engine a few minutes before changing the oil
to warm it. Warm oil flows better and carries more
contaminants.
1. Perform the pre-maintenance procedures; refer to
Preparing for Maintenance.
2. Turn the fuel valve to the Off position to prevent
any fuel leakage.
3. Remove the dipstick (Figure 41).
Figure 41
4. Tip the mower onto its side, with the air filter up,
to drain the used oil out through the oil fill tube
(Figure 42).
Figure 42
5.
Slowly
pour oil into the oil fill tube, periodically
checking the level with the dipstick, until the dipstick
indicates that the engine is full as illustrated in
Figure 43.
Do not overfill.
(Max. fill: 0.58 quart
(0.55 l), type: SAE 30 detergent oil with an API
service classification of SH, SJ, SL, or higher.)
Note:
Each time you check the oil level, remove the
dipstick and wipe it clean, insert it into the oil filler
neck (but do not screw it in), then remove it again
and check the level (Figure 43).
Note:
If you overfill the engine, pour some oil out
of it.
