GENERAL
DO NOT use gasoline left over from previous season. Old
or stale dirty gasoline
can cause starting
and running
problems.
Replace your gasoline can, ff your old can starts to rust.
DO NOT use rusty gasoline can, rust and/or dirt in your
gasoline can cause problems.
STORAGE
Never store engine with gasoline in tank, indoors or in
closed, poorly ventilated areas where gasoline fumes may
reach an open flame, spark or pilot light as on a furnace,
water heater, or clothes dryer,
etc.
It is important
to prevent gum deposits from forming in
essential fuel system parts such as the carburetor, fuel
filter, fuel hose, or tank during storage. Also, experience
indicates that alcohol blended fuels (called gasohol or us-
ing ethanol or methanol) can attract moisture which leads
to separation
and formation
of acids during storage.
Acidic gas can damage the fuel system of an engine while
in storage.
To avoid engine problems, the fuel system should be emp-
tied before storage of 30 days or longer. Follow these
instructions:
If your engine is not to be used for 30 days or more
prepare
as follows:
Drain gasoline from Fuel tank; gasoline in gasoline tank
and carburetor
will form deposits and cause problems in
starting
and running your engine.
When preparing
your mower for storage it is a good time
to service your mower and engine to be ready for the next
mowing
season. Replace such parts as mower blade,
spark plug and air filter.
CHANGE
OIL: Warm oil drains better.
Drain old oil and replace with fresh clean Sears SAE 30W
oil.
See "To Change Oil'" section under Maintenance.
Remove spark plug and put 2 or 3 tablespoons
of off into
spark plug
opening
and pull starter
rope slowly
to
distribute oil, installnew
spark plug and tighten.
DO NOT PUT ANY ADDITIVES IN OASOLINE
OR OIL.
CLEANMOWER/ENGINE
CAUTION:
Before cleaning
mower,
disconnect spark
plug wire and ptace wire where it cannot come in contact
with the spark plug.
Clean around engine and on top of mower. Scrape under-
side of mower using putty knife or similar toot to remove
any build-up
of trash or grass on underside
of mower
housing.
NOTE: We DO NOT recommend using a water hose to
clean your mower unless the electrical system, muffler, air
filter and carburetor
are covered
to keep water out.
Water in engine can result in shortening
engine life.
CHECKFASTENERS
Check all fasteners and be sure they are tight: tighten
and!or replace any loose or worn Fasteners.
GEASSCATCHER
Check your grass catcher often for damage or deteriora-
tion. Through normal use it wilt wear. If catcher needs
replacing,
replace only with a man ufacturer approved
replacement catcher from Sears. Give the mower model
when ordering.
NOTE: The catcher may be hosed with water, but must
be dry when used.
REPLACE BLADE
See "Blade Care" section under Maintenance.
To get the
best cutting results we recommend that you inspect mower
blade for sharpness,
wear and damage
each year.
If
necessary, replace with a Sears original equipment blade.
Replacement blade is available
at most Sears stores and
through the catalog.
Be sure to give your mower model
number when ordering
blade.
We DO NOT recommend
sharpening
blade - you can
keep the cutting edge touched up with a file. Grinding the
cutting edge excessively can cause the blade to be out
of balance. An unbalanced
blade can cause excessive
vibration
and shorten the life of the engine and mower.
