BEFORE
STARTINGENGINE
OIL:
•

•

Remove engine oil cap with dipstick or oil fill plugo
Fill to "FULL"
line on dipstick or to top of slot
clown in filler hole. Use about I pint or 1!2 liter
of Sears 30W oil or equivalent. SAE 10W 30 oil
can also be used. DO NOT use SAE 10W 40 oil.
The total oil capacity of your engine is 21 oz. or
0.62 liters. Fill only to "FULL" line on dipstick or
to top of slot down
in oil filler
holeo
DO NOT over fill. The first fill on a new engine
uses about 1 pint. Check oil level and add oil as
needed to bring to proper level.
Pour oil slowly, DO NOT over fill.

GAS:
* Fill gasoline tank with fresh, clean unleaded
gasoline. DO NOT USE PREMIUM GASOLINE.
BE CAREFUL NOT TO OVER FILL TANK (SEE
FIG. 2)_
WARNING: Experience indicates that alcohol blended fuels (called gasohol or using 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 shouldbe
emptied before storage for 30 days or longer. Drain
the gas tank, start the engine and let it run until the
fuel/ines and carburetor are empty. Use fresh fuel

FIG, 4
next season. See Storage Instructions for additional
informatiom
Never use engine or carburetor cleaner products in
the fuel tank or permanent damage may occur.

TO STARTENGINE
= To start a cold engine, push primer five (5) times
before trying to start. Use a firm push. This step
is not usually necessary when starting an engine
which has already run for a few minutes.
* Push engine speed selector lever forward to
"HIGH"
position.
* Hold operator presence control bar down to the
handle and pull starter handle quickly. Do not
allow starter rope to snap back.
* To "STOP"
engine, release operator presence
control bar.
NOTE: In cooler weather it may be necessary to
repeat priming steps. In warmer weather over priming may cause flooding and engine wilt not start° If
you do flood engine wait a few minutes before attempting to start and DO NOT repeat priming steps.

OPERATION
IPIIII

MOWINGTIPS
,'

Under certain conditions, such as very tall grass,
it may be necessary to raise the height of cut to
reduce
pushing effort and to keep from
overloading the engine and leaving clumps of
grass clippings_
* For extremely heavy cutting, reduce the width of
cut and raise the rear of the mower housing one
(I) wheel adjuster setting higher than the front for
better discharge of grass_
o When using a rear bagging mower in moist,
heavy grass, clumps of cut grass may not enter
the grass catcher. Reduce groundspeed (pushing
speed) andlor run the mower over the area a seo
cond time.
*

•

If a trail of grass clippings is left on the right side
of a rear bagging mower, mow in a clockwise
direction with a small overlap to collect the clippings on the next pass.
', For' side discharge mowers, cutting in a counterclockwise direction, starting at the outside of the
area to be cut, spreads grass clippings more evenly and puts lessload on the engine. To keep clippings off of walkways,
flower beds, etc., make
the first cuts in a clockwise direction.
• Pores in cloth grass catchers can become filled
with dirt and dust with use and catchers will collect less grass. To prevent this, regularly hose catcher off with water and let dry before using.

For better' grass bagging and most cutting conditions, the engine speed should be set in the
"HIGH"
(fast) position.

NOTE: Check tab in blade flange after removing_ If

mend that a new blade nut be used each time blade
is removed.
TO REPLACE BLADE:
•

1"O REMOVE BLADE:
" Turn mower on its side. Make sure air filter and
carburetor are up.
• Use block of wood between blade and mower

•

housing to prevent blade from turning when nut
isremoved. Protect your hands with gloves and/or
wrap blade with heavy cloth.
Remove nut by turning counter-clockwise.
Use a
15116" box or open-end wrench.

•

•
•

Put blade flange on engine crankshaft with tab
in slot (See Fig_ 5).
Fit blade on crankshaft in the blade flange. Be
sure the word "TOP"
(stamped on blade) is
toward engine.
Place flat washer, two (2) formed washers and
nut on crankshaft (See Fig. 5).
Use block of wood to hold blade and tighten nut

NOTE: We do not recommend Sharpening blade - but"
if you do, be sure the blade is balanced°
TO SHARPEN BLADE:
o The blade can be sharpened with a file or on a
grinding wheel. Do not attempt to sharpen while
on the mower.
• Care should be taken to keep the blade balanced. An unbalanced blade will cause excessive
vibration when running and eventual damage to
mower or engine.
o To check blade balance, drive a nai! into a beam
or wall. Leave about one inch of the straight nail
expose& Place center hole of blade over the head
of the nail. If blade is balanced, it should remain
in a horizontal position. If either end of the blade
moves downward,
blade
is not balanced.
Sharpen
