MAINTENANCE

GENERAL REC OM MEN DA TIONS

The warranty on this lawn mower does not 
cover items that have been sub ject ed to 
operator abuse or negligence.  To receive 
full value from the warranty, operator must 
maintain unit as in struct ed in this manual.
Some adjustments will need to be made 
periodically to properly maintain your unit.
At least once a season, check to see if 
you should make any of the adjustments 
described in the Service and Ad just ments 
section of this manual.
•  At least once a year, replace the spark 

plug, clean or replace air fi lter element 
and check blade for wear.  A new spark 
plug and clean/new air fi lter element 
assure proper air-fuel mix ture and help 
your engine run bet ter and last longer.

•  Follow the maintenance schedule in this 

manual.

BEFORE EACH USE

•  Check engine oil level.
