GENERAL RECOMMENDATIONS

The warranty on this lawn mower does not cover items that have been subjected to operator abuse or negli- gence. To receive full value from the warranty, opera- tor 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 Adjustments 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 mixture and help your engine run better and last longer.

Follow the maintenance schedule in this manual.

BEFORE EACH USE

1.Check engine oil level.

2.Check for loose fasteners.

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.
