Inspecting the Rotor Blades
Service Interval: Every 25 hours
Yearly
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
25).
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
Every 50 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 shuts off.
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 pan
4. After draining the used oil, return the machine to the
operating position.
5. Install the oil-drain plug and tighten it securely.

2. The wear-indicator hole
is exposed; replace both
rotor blades.

6. Clean around the oil-fill cap
1. Oil-fill cap
7. Unscrew the oil-fill cap and remove it
8. With the machine in the operating position, carefully
pour oil into the oil-fill hole. Wait 3 minutes for the
oil to settle and add enough to bring it to the point of
overflow. There should be very little, if any, oil left in
the bottle
(Figure
Note: You may tip the machine forward (handle up)
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: 0.60 L (20 oz), type: automotive detergent oil
with an API service classification of SJ, SL, or higher.
