See “TO ADJUST CUTTING HEIGHT” in the Operation 
section of this manual.

NOTE:  Before tipping lawn mower to drain oil, empty fuel 
tank by running engine until fuel tank is empty.

1.    Disconnect spark plug wire from spark plug and place 

wire where it cannot come in contact with spark plug.

2.    Remove engine oil cap; lay aside on a clean surface.

3.    Tip lawn mower on its side as shown and drain oil into 

a suitable container. Rock lawn mower back and forth 
to remove any oil trapped inside of engine.

The rear defl ector, attached between the rear wheels of 
your mower, is provided to minimize the possibility that 
objects will be thrown out of the rear of the mower into 
the operator's mowing position.  If the defl ector becomes 
damaged, it should be replaced.

4.   Wipe off any spilled oil from lawn mower or side of 

engine.

5.   Slowly pour oil down the oil fi ll spout, stopping every 

few ounces to check the oil level with the dipstick.

6.    Stop adding oil when you reach the FULL mark on the 

dipstick.  Wait a minute to allow oil to settle.

7.    Continue adding small amounts of oil, rechecking the 

dipstick until oil level settles at FULL.  DO NOT over-
fi ll, or engine will smoke heavily from the muffl er on 
startup.

8.    Always be sure to retighten oil dipstick before starting 

engine.

9.    Re con nect spark plug wire to spark plug.

Your engine will not run properly and may be damaged 
by using a dirty air fi lter. Replace the air fi lter every 100 
hours of operation or every season, whichever occurs fi rst.  
Ser vice air cleaner more often under dusty conditions.  See 
the main te nance section of your engine manual.

Inspect and replace corroded muffl er as it could create a 
fi re hazard and/or damage.

Replace spark plug at the beginning of each mowing season 
or after every 100 hours of operation, whichever occurs 
fi rst.  Spark plug type and gap setting are shown in the 
“PROD UCT SPEC I FI CA TIONS” section of this manual.

IMPORTANT:  FOR BEST PERFORMANCE, KEEP MOWER 
HOUSING FREE OF BUILT-UP GRASS AND TRASH.  CLEAN 
THE UNDERSIDE OF YOUR MOWER AFTER EACH USE.

•      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 fi nished surfaces and wheels free of gasoline, oil, etc.

•      We do not recommend using a garden hose to clean 

lawn mower unless the electrical system, muffl er, air 
fi lter and carburetor are covered to keep water out.  
Water in engine can result in shortened engine life.

Clean under drive cover at least twice a season. Scrape un-
derside of cover with putty knife or similar tool to remove any 
build-up of trash or grass on underside of drive cover.
