A dirty air filter restricts air flow to the carburetor, reducing engine 
performance. If you operate the mower in very dusty areas, clean the 
air filter more often than specified in the MAINTENANCE SCHEDULE 
(page 9).

Operating the engine without an air filter or with a damaged filter 
allows dirt to enter the engine, causing rapid engine wear. This type of 
damage is not covered by the Distributor’s Limited Warranty
(page 19).

1. Press down on the cover tabs and remove the cover.

2. Remove the filter from the air cleaner housing. 

3. Inspect the filter and replace it if it is damaged.

4. Clean the filter by tapping it several times on a hard surface to 

remove dirt, or blow compressed air (not exceeding 30 psi
[207 kPa]) through the filter from the inside. Never try to brush off 
dirt; brushing will force dirt into the fibers.

5. Use a moist rag to wipe dirt from the inside of the air cleaner 

housing and cover. Be careful to prevent dirt from entering the air 
duct that leads to the carburetor.

6. Reinstall the filter and cover.

For good performance, the spark plug must be properly gapped and 
free of deposits.

1. Disconnect the spark plug 

cap and remove any dirt 
from around the spark plug 
area.

2. Remove the spark plug with 

a 13/16 in (21 mm) spark 
plug wrench. 

3. Inspect the spark plug. 

Replace it if the electrodes 
are worn, or if the insulator 
is cracked or chipped.

4. Measure the spark plug 

electrode gap with a 
suitable gauge. The gap 
should be 0.028 ~ 
0.031 in (0.7 ~ 0.8 mm). 
Correct the gap, if 
necessary, by carefully 
bending the side 
electrode.

5. Install the spark plug 

carefully, by hand, to 
avoid cross-threading.

6. After the spark plug 

seats, tighten with a 
13/16 in (21 mm) spark 
plug wrench to 
compress the washer.

If reinstalling the old spark plug, tighten 1/8 to 1/4 turn after the 
spark plug seats.

If installing a new spark plug, tighten 1/2 turn after the spark plug 
seats to compress the sealing washer.

7. Install the spark plug cap on the spark plug.

This engine is certified to operate on unleaded gasoline with a pump 
octane rating of 86 or higher. 

Refuel in a well-ventilated area with the engine stopped. If the engine 
has been running, allow it to cool first. Never refuel the engine inside a 
building where gasoline fumes may reach flames or sparks.

You may use regular unleaded gasoline containing no more than 10% 
Ethanol (E10) or 5% Methanol by volume. In addition, Methanol must 
contain cosolvents and corrosion inhibitors. Use of fuels with content 
of Ethanol or Methanol greater than shown above may cause starting 
and/or performance problems. It may also damage metal, rubber, and 
plastic parts of the fuel system. Engine damage or performance 
problems that result from using a fuel with percentages of Ethanol or 
Methanol greater than shown above are not covered under warranty.
