Inspecting the Rotor Blades
Service Interval: Yearly—Inspect the rotor blades and have
an Authorized Service Dealer replace the

have an Authorized Service Dealer replace the rotor blades
and the scraper (Figure 27).

Changing the Engine Oil
Service Interval: After the first 2 hours
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 (refer to
Figure 13) and that the fuel cap is securely in place.
2. Move the machine to a level surface.
3. Place an oil drain pan under the oil drain plug
(Figure 12), remove the oil drain plug, and tip the
machine backward (handle down) halfway to the
ground to drain the used oil into the oil drain pan.
Important: Do not tip the machine all the way
back to the ground, or fuel may leak out of the
machine.
4. After draining the used oil, return the machine to the
operating position.
5. Install the oil drain plug and tighten it securely.
6. Clean around the oil fill cap (Figure 12).
7. Unscrew the oil fill cap and remove it.
8. Slowly pour oil into the oil fill hole. Wait 3 minutes,
then check the oil level on the dipstick by wiping the
dipstick clean and then inserting, but not screwing in,
the oil fill cap into the hole.
Note: To determine the proper oil level on the
dipstick, refer to Figure 28.
