CUSTOMER RESPONSIBILITIES
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. All adjustments in the Service
and Adjustments section of this manual should be checked
at least once each season.
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.
BEFORE EACH USE
Check engine oil level.
Check for loose fasteners.
LUBRICATION
Keep unit well lubricated.
IMPORTANT: DO NOT OIL OR GREASE PLASTIC WHEEL
BEARINGS. VISCOUS LUBRICANTS WILL ATTRACT
DUST AND DIRT THAT WILL SHORTEN THE LIFE OF
THE SELF-LUBRICATING BEARINGS. IF YOU FEEL
THEY MUST BE LUBRICATED, USE ONLY A DRY,
POWDERED GRAPHITE TYPE LUBRICANT SPARINGLY.
