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
assures proper air-fuel mixture and
helps 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
Keep unit well lubricated (See "LUBRI-
CATION CHART").

Spray lubricant
IMPORTANT:
Do not oil or grease
plastic wheel bearings, viscous lubri-
cants 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.
