Inspecting the Rotor Blades
Service Interval
Yearly. Inspect the rotor blades and have an
Authorized Service Dealer replace the rotor
blades and scraper if necessary.
Before each session, inspect the rotor blades
for wear. When a rotor blade edge has worn
down to the wear indicator hole, have an
Authorized Service Dealer replace the rotor
blades and the scraper (Figure 20).
Changing the Engine Oil
Service Interval
After the first 2 hours, then yearly. Run the
engine a few minutes before changing the
oil to warm it. Warm oil flows better and
carries more contaminants.

1.
Ensure that the fuel tank is not overfilled
(Figure 8) and that the fuel cap is secure.

Remove the drain plug, and tip the machine
backward (handle down) halfway to the
ground to drain the used oil into the drain pan.
Important: Do not tip the machine all the
way to the ground or fuel may leak out.
4.
After draining the used oil, return the
machine to the operating position.
5.
Re-install the drain plug and tighten it securely.
