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 Cleaner

Clean the air cleaner after every 25 operating hours. Clean
it more frequently if you operate the lawn mower in dusty
or dirty conditions.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug (Fig. 22).

from the air cleaner body. Clean the foam element
thoroughly.
A. Wash the foam element in a solution of liquid soap
and warm water. Squeeze the foam element to
remove dirt, but do not twist it because the foam
may tear. Rinse the foam element thoroughly in
clear water.
B. Dry the foam element by wrapping it in a clean
rag. Squeeze the rag and the foam element to dry.
C. Saturate the element with engine oil. Squeeze the
foam element to remove the excess oil and to
distribute the oil thoroughly. A damp foam element
is desirable.
5. Install the foam element and the air cleaner cover.
Important Do not operate the engine without the air
cleaner element because extreme engine wear and damage
will likely result.
