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 28).
1. The wear indicator hole is
intact; you do not need to
replace the rotor blades.
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. Siphon the fuel from the fuel tank into an approved
fuel container, or run the engine until it stops.
2. Move the machine to a level surface.
3. Place an oil drain pan under the oil drain plug,
remove the oil drain plug, and tip the machine
backward and drain the used oil in the oil drain pan
Figure 29).
Figure 28
2. The wear indicator hole is
exposed; replace the rotor
blades.

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 30).
1. Oil fill cap
7. Unscrew the oil fill cap and remove it (Figure 30).
8. With the machine in the operating position, carefully
pour oil into the oil fill hole. Wait three minutes,
then add oil to the point of overflow (Figure 32).
Note: You may tip the machine forward (handle
up) a little to make adding oil easier. Remember to
return the machine to the operating position before
checking the oil level.
Important: Do not tip the machine all the way
forward onto its nose, or fuel may leak out of
the machine.
Max fill: 20 oz. (0.6 l), type: automotive detergent oil
with an API service classification of SJ, SL, or higher.
