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.

•Follow the maintenance schedule in this manual.

BEFORE EACH USE

•Check engine oil level.

•Check for loose fasteners.

LUBRICATION

Keep unit well lubricated

(See “LUBRICATION CHART”).

LUBRICATION CHART

➀ Wheel adjuster (on each wheel)

➁ Engine oil

➀ Mulcher door hinge pin

➀ Rear door hinge

➀ Handle bracket mounting pins

➀ Spray lubricant

➁ See "ENGINE" in Maintenance section.

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.
