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 unit 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 Adjustments
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.

do not turn freely, contact a Husqvarna or
other qualified service center.
