AIR FILTER

Your engine will not run properly and may

GRASS CATCHER

(If purchased as an accessory)
•   The grass catcher may be hosed with 

water, but must be dry when used.

•   Check your grass catcher often for dam-

age or de te ri o ra tion.  Through normal 
use it will wear. If catcher needs replac-
ing, replace only with ap proved replace-
ment catcher shown in the Repair Parts 
section of this manual.  Give the lawn 
mower model number when ordering.

ENGINE

LUBRICATION

Use only high quality detergent oil rated with 
API service classifi cation SG–SL.  Select the 
oil's SAE viscosity grade according to your 
expected operating temperature.

NOTE:

  Although multi-viscosity oils (5W30, 

10W30 etc.) improve starting in cold weather, 
they will result in in creased oil consumption 
when used above 32°F.  Check your engine 
oil level more frequently to avoid possible 
engine damage from running low on oil.
Change the oil after every 25 hours of opera-
tion orat least once a year if the lawn mower 
is not used for 25 hours in one year.
Check the crankcase oil level before 
starting the engine and after each fi ve (5) 
hours of continuous use. Tighten oil plug 
securely each time you check the oil level.

TO CHANGE ENGINE OIL 
1.   Disconnect spark plug wire from spark 

plug and place wire where it cannot 
come in contact with plug.

2.   Be sure lawn mower is on level surface.

NOTE

:  Oil will drain more freely when 

warm.  Catch oil in a suitable container.
3.   Remove bottom oil drain plug.
