GENERAL RECOMMENDATIONS

The warranty on this tiller does not cover items that  have 
been subjected to operator abuse or negligence.  To receive 
full value from the warranty, the operator must main tain tiller 
as instructed in this manual.

Some adjustments will need to be made periodically to 
properly maintain your tiller.

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.
•      Once a year you should replace the spark plug, clean 

or replace air fi lter, and check tines and belts for wear.  
A new spark plug and clean air fi lter assure proper 
air-fuel mixture and help your engine run better and 
last longer.

BEFORE EACH USE

•      Check engine oil level.
•      Check tine operation.
•      Check for loose fasteners.

LUBRICATION

Keep unit well lubricated (See “LUBRICATION CHART”).
