OIL (See Fig, 6)

Your lawn mower is shipped without oil in the engine°
•
Be sure mower is level and area around oil fill is clean
•
Remove engine oil cap wtdipstick and fill to the full line on
the dipstick..
Use 20 ozso of oil. For type and grade of oil to use, see
ENGINE in Customer Responsibilities section of this
manual

OPERATION
•
•
o
•
.

Pour oil slowly Do not over fill.
Check oil level before each use. Add oil ifneeded. Fili to
full line ot_ dipstick
To read proper _evel, tighten engine oil cap each time.
Reinstall engine oil cap and tighten,
After the first two (2) hours of mowing, change the oil, and
every 25 hours thereafter You may need to change the
oil more often under dusty, dirty conditions

For extremely heavy cutting, reduce the width of cut by
overlapping previously cut path and mow slowly,,

•

For better grass bagging and most cutting conditio#s,
the engine speed should be set in the fast (@)
position_

For side discharge lawn mowers, cutting in a counterclockwise direction, starting at the outside of the area
to be cut, spreads grass clippings more evenly and
puts less load 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,
'

Keep top of engine around starter clear and clean of
grass clippings and chaff. This will help engine airflow
and extend engine life.

GAS (See Fig. 6)
•

Fill gasoline tank with fresh, clean, unleaded gasoline.
DO NOT USE PREMIUM GASOLINE. BE CAREFUL
NOT TO OVER FILL TANK.

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 should be emptied before storage of 30 days or ionger_ Drain the fuel tank, start the
engine and let it run until fuel lines and carburetor are
empty. Use fresh fuel next season. See Storage Instructions for additional information.
Never use engine or
carburetor cleaner products in fuel tank or permanent
damage may occur.

MULCHING

To start a cold engine, push primerfive (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.

•

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.

TBPS

•

The special mulching blade will recut the grass clippings many times and reduce them in size so that as
they fall onto the lawn they will disperse into the grass
and not be noticed, Also, the mulched grass will
biodegrade quickly to provide nutrients for the lawn.
Always mulch with your highest engine (blade) speed
as this will provide the best recutting action of the
blades.

Avoid cutting your lawn when it,is wet. Wet grass tends
to form clumps and interferes with the mulching action,
The best time to mow your tawn is the early afternoon,
At this time the grass has dried and the newly cut area
will not be exposed to the direct sun.

For best results, adjust the lawn mower cutting height
so that the lawn mower cuts off only the top one4hird
of the grass blades (See Fig.. 7). If the lawn is overgrown it will be necessary to raise the height of cut to
reduce pushing effort and to keep from overloading the
engine and leaving clumps of mulched grass. For
extremely heavy mulching, reduce your width of cut by
overlapping previously cut path and mow slowly.

Certain types of grass and grass conditions may require that an area be mulched a second time to completely hide the clippings. When doing a second cut,
mow across or perpendicular to the first cut path.

•

Change your cutting pattern from week to week, Mow
north to south one week then change to east to west the
next week. This will help prevent matting and graining
of the lawn.

To check blade baiance, drive a nail into a beam orwall.
Leave about one inch of the straight nait exposed.
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,
sharpen the heavy end until the blade is balanced.

Check your grass catcher often for damage or deterioration. Through normal use it will wear. If catcher

BEFORE NEXT OIL CHANGE

NOTE: Although multi-viscosity oits (5W30, t0W30 etc.)
improve starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above
32°F. Check your engine oil level more frequently to avoid
possible engine damage from running low on oil.
Change the oil after the first two hours of operation and
every 25 hours thereafter or at least once a year if the lawn
mower is not used for 25 hours in one year.
Check the crankcase oil level before starting the engine
and after each five (5) hours of continuous use. Tighten oil
