Cleaning the Discharge Tunnel
and Plug
Remove the plug from the discharge tunnel and clean it
after each use.
Always be sure that the discharge tunnel door closes
securely when you release the handle. If the debris
prevents the discharge door from closing securely, clean
the inside of the discharge tunnel and the door thoroughly.
Warning
Grass clippings and other objects can be thrown
from an open discharge tunnel and cause serious
injury or kill the operator or bystanders.
Never start or operate the lawn mower unless one
of the following is true:
•
The discharge tunnel plug is locked securely in
the discharge tunnel.
•
The grass bag is locked in place.
•
The optional side discharge chute is locked in
place.
•
The discharge tunnel door is locked in place.
Servicing the Air Filter
Clean the foam pre-cleaner every 25 operating hours.
Replace the paper air filter once every season or every
300 operating hours; replace it more frequently in dusty
conditions.
Important
Do not operate the engine without the air
filter assembly; extreme engine damage will occur.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug (Fig. 9).
3. Remove the screw that secures the air cleaner cover
(Fig. 21).

Important
Do not try to clean a paper filter.
6. Remove the foam pre-cleaner and wash it with a mild
detergent and water, then blot it dry (Fig. 21).
7. Saturate the pre-cleaner with clean engine oil, then
squeeze it (do not twist) to remove the excess oil.
8. Install the foam pre-cleaner.
9. Install the new paper air filter.
10. Install the cover and secure it with the screw.
Changing the Engine Oil
Change the oil after the first 8 operating hours and than
after every 50 operating hours or every season (more
frequently in dusty or dirty conditions).
1. Run the engine to warm the engine oil.
Note: Warm oil flows better and carries more
contaminants.
Warning
Oil may be hot after engine has been run, and
contact with hot oil can cause severe personal
injury.
Avoid contacting the hot engine oil when you
drain it.
2. Stop the engine and wait for all moving parts to stop.
3. Disconnect the wire from the spark plug (Fig. 9).
4. Place a suitable drain pan beside the right side of the
lawn mower.
5. Remove the dipstick by rotating the cap
counterclockwise and pulling it out (Fig. 6).
