to dry out the moisture on the lawn mower and its
components.

blade brake system and the traction drive several times
to dry them out.
Scraping Method
If washing does not remove all the debris from under the
lawn mower, tip it and scrape it clean.
1. Disconnect the wire from the spark plug (Fig. 8).
2. Drain the gasoline from the fuel tank; refer to steps 3
and 4 of Emptying the Fuel Tank on page 23.
WARNING
POTENTIAL HAZARD
Gasoline is extremely flammable, highly
explosive and under certain conditions can
cause personal injury or property damage.
WHAT CAN HAPPEN
Tipping the lawn mower may cause fuel leakage
from the carburetor or fuel tank.
HOW TO AVOID THE HAZARD
Avoid fuel spills by running the engine dry or
removing gas with a hand pump; never siphon.
3. Tip the lawn mower onto its left side.
4. Remove dirt and grass clippings with a hardwood
scraper. Avoid burrs and sharp edges.
5. Turn the lawn mower upright.
6. Fill the gas tank.
7. Connect the spark plug wire.

Servicing the Air Filter

Clean the air filter pre-cleaner after every 25 operating
hours or every season. Clean the paper cartridge after
every 100 operating hours or every season. Clean more
frequently in dusty or dirty operating conditions. Replace
the air cleaner parts if they are very dirty.
Do not operate the engine without the air filter
element; extreme engine wear and damage can occur.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug (Fig. 8).
3. Remove the two knobs that secure the air filter cover
to the engine (Fig. 20).
