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
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 44).
Figure 44
4. Tip the mower onto its side, with the air filter up, to
drain the used oil out through the oil fill tube (Figure
45).
Figure 45
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
46.
Do not overfill.
(Max. fill: 0.58 quart (0.55 l),
type: SAE 30W 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 5).
Note:
If you overfill the engine, pour some oil out
of it.
Figure 46
6. Install the dipstick securely.
7. Dispose of the used oil properly at a local recycling
center.
