GENERAL RECOMMENDATIONS
The warranty on this lawn mower does not cover items that
have been subjected to operator abuse or negligence. To
receive full value from the warranty, operator must maintain
mower as instructed 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-
justments section of this manual.
• At least once a year, replace the spark plug, clean or
replace air filter element and check blade for wear. A
new spark plug and clean/new air filter element assure
proper air-fuel mixture and help your engine run better
and last longer.
• Follow the maintenance schedule in this manual.
