Preparing for Maintenance
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the spark plug wire from the spark plug
and hook it onto the retaining post (Figure 24) before
performing any maintenance procedure.
Figure 24
3. After performing the maintenance procedure(s),
connect the spark plug wire to the spark plug.
Important: Before tipping the mower to change
the oil or replace the blade, allow the fuel tank to
run dry through normal usage. If you must tip the
mower prior to running out of fuel, use a hand fuel
pump to remove the fuel. Always tip the mower
onto its side, with the air filter up.
Tipping the mower may cause the fuel to leak.
Gasoline is flammable, explosive and can cause
personal injury.
Run the engine dry or remove the gasoline with a
hand pump; never siphon.
Replacing the Air Filter
Replace the air filter yearly; replace it more frequently
in dusty operating conditions. Refer to Preparing for
Maintenance.
1. Use a screw driver to open the air filter cover (Figure
25).
Figure 25
2. Replace the air filter (Figure 26).
Figure 26
3. Install 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. Refer to Preparing for Maintenance.
2. Remove the dipstick (Figure 27).
Figure 27
3. Tip the mower onto its side with the air filter up to drain
the used oil out through the oil fill tube (Figure 28).
Figure 28
4. Slowly pour oil into the oil fill tube until the oil level
reaches the Full line on the dipstick (Figure 29). Do
not overfill. (Max. fill: 20 oz. (0.59 l), type: SAE 30W
detergent oil with an API service classification of SF,
SG, SH, SJ, SL, or higher.)
