LUBRICATION
CHART
The warranty
on this tractor
does not cover
items that have been subjected
to operator
abuse
or negligence.
To receive
full value
from
the warranty,
operator
must
maintain
tractor
as instructed
in this manual.
Some adjustments
will need to be made pe-
riodically
to properly
maintain
your tractor.
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 you should
replace
the spark
plug,
clean
or replace
air filter,
and check
blades
and belts for wear.
A
new spark plug and clean
air filter ensure
proper
air-fuel
mixture
and help your en-
gine run better
and last longer.

iMPORTANT:
Do not oil or grease
the pivot
points
which
have
special
nylon
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 lu-
bricant
sparingly.
