Replace spark plug at the beginning of each mowing 

season or after every 100 hours of operation, whichever 

occurs first.  Spark plug type and gap setting are shown in 

the “PROD UCT SPEC I FI CA TIONS” section of this manual.

The fuel filter should be replaced once each season.  If fuel 

filter becomes clogged, ob struct ing fuel flow to car bu re tor, 

re place ment is re quired.
1.  With engine cool, remove filter and plug fuel line sec tions 

(Figure 25).

2.  Place new fuel filter in position in fuel line with arrow 

pointing towards carburetor.

3.  Be sure there are no fuel line leaks and clamps are 

properly positioned.

4.  Immediately wipe up any spilled gasoline.

Inspect and replace corroded muffler as it could create a 

fire hazard and/or damage.

•  Clean the underside of your lawn mower by scraping 

to remove build-up of grass and trash.

•  Clean engine often to keep trash from accumulating.  

A clogged engine runs hotter and shortens engine life.

• 

Keep finished surfaces / wheels free of gasoline, oil, etc.

•  We do not recommend using a garden hose to clean 

lawn mower unless the electrical system, muffler, air 

filter and carburetor are covered to keep water out.  

Water in engine can result in shortened engine life.

IMPORTANT:  FOR BEST PERFORMANCE, KEEP MOWER 

HOUSING FREE OF BUILT-UP GRASS AND TRASH.  CLEAN 

THE UNDERSIDE OF YOUR MOWER AFTER EACH USE.

6.  Shut off the engine.
7.  Shut off water supply and remove hose from fitting.

Your lawn mower is equipped with a fitting that allows quick 

and easy cleaning of the underside of the housing.  To use 

this feature, proceed as follows:
1.  Move lawn mower to an area of cut grass or another 

hard surface.

NOTE: Water, grass and other debris will drain from beneath 

the mower housing during the washout process.
2.  Remove grass catcher and discharge chute assembly 

from lawn mower.

3.  Close mulcher door (if equipped).
4.  Connect a garden hose to the fitting where shown 

(Figure 26).

IMPORTANT:  BE SURE THE GARDEN HOSE IS NOT ROUTED 

UNDER THE LAWN MOWER HOUSING OR ENTANGLED IN 

THE WHEELS.

5.  Turn on water supply and check for leaks at the fitting.
If no leaks are present, start engine (as described in the 

Operation section of this manual) and let engine run until 

the underside of the lawn mower is clean.

8.  Start engine (as described in the Operation section 

of this manual) and let engine run for a full minute to 

remove excess water from mower.
