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.)
