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 adjust-
ments 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
1. Check engine oil level,
2. Check for loose fasteners.
LUBRICATION

CATION CHART").

IMPORTANT: Do not oil or grease
plastic wheel bearings. Viscous
lubricants will attract dust and dirt that
will shorten the life of the self-lubricat-
ing bearings. If you feel they must be
lubricated, use only a dry, powdered
graphite type lubricant sparingly.
