OPERATION

BEFORE STARTING ENGINE

OIL (See Fig. 11)

A 20 oz. bottle of Pennzoil SAE 30 oil is included with your

new lawn mower.

• Remove engine oil cap and fill to the FULL line on the
dipstick.

• Use 20 ozs. of oil. For type and grade of oil to use, see
"ENGINE“ in Customer Responsibilities section of this
manual.

• POUR OIL SLOWLY. DO NOT OVER FILL

• Check oil level before each use. Add oil if needed. Fill
to FULL line on dipstick.

• To read proper level, 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.

GAS (See Fig. 11)

• 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 for 30 days or longer. Drain the gas
tank, start the engine and let it run until the 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 the fuel
tank or permanent damage may occur.

OPERATION

MOWING TIPS

• 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 en
gine and leaving clumps of grass clippings.

• For extremely heavy cutting, reduce the width of cut
and raise the rear of the lawn mower housing one (1 )
wheel adjuster setting higher than the front for better

discharge of grass.

• For better grass bagging and most cutting conditions,
the engine speed should be set in the "'HIGH" {*^)

(FAST) position,

« When using a rear discharge lawn mower in moist,

heavy grass, clumps of cut grass may not enter the
grass catcher. Reduce ground speed (pushing speed)
and/or run the lawn mower over the area a second

time.

• If a trail of grass clippings is left on the right side of a
rear discharge lawn mower, mow in a clockwise
direction with a small overlap to collect the clippings

on the next pass.

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

. 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 catchers off
with water and let dry before using.

MULCHING MOWING TIPS

IMPORTANT: FOR BEST PERFORMANCE, KEEP
MOWER HOUSING FREE OF BUILT-UP GRASS AND

TRASH. CLEAN AFTER EACH USE. SEE "CLEANING"

IN CUSTOMER RESPONSIBILITIES SECTION OF THIS

MANUAL. .

• The special mulching blade will reçut the grass clip
pings 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.

FIG. 12

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 lawn 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 one-third
of the grass blades (See Fig. 12). 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,
mow slowly and raise the rear of the lawn mower one
wheel adjuster setting higher than the front.

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.

11

CUSTOMER RESPONSIBILITIES

1 ■ Change more often when operating under a heavy load or in high ambient temperatures.
2 - Service more often when operating in dirty or dusty conditions.
3 - Replace blades more often when mowing in sandy soil.

CUSTOMER RESPONSIBILITIES

ENGINE

LUBRICATION

Use only high quality detergent oil rated with API service
classification SG. Select the oil's SAE viscosity grade
according to your expected operating temperature.

NOTE: Although multi-viscosity oils (5W30, 10W30 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 26 hours in one year.

Check the crankcase oil level before starting the engine
and after each five (5) hours of continuous use. Tighten oil
plug securely each time you check the oil level.

TO CHANGE ENGINE OIL (See Fig. 14)

• Disconnect spark plug wire from spark plug,

• Remove engine oil cap; lay aside on a clean surface.

• Tip lawn mower on its side and drain oil into a suitable
container. Rock lawn mower back and forth to remove

any oil trapped inside of engine.

• Wipe off any spilled oil on iawn mower and on side of
engine.

• Fill engine with SAE 30 or 10W 30 oil. All oil must meet
API service classification SG. Fill only to the "FULL"

line on the dipstick. DO NOT OVER FILL.

• Replace engine oil cap.

• Reconnect spark plug wire to spark plug.

AIR FILTER '

minimizing the formation of fuel gum deposits during stor
age. Add stabilizer to gasoline in fuel tank or storage
container. Always follow the mix ratio found on stabilizer
container. Run engine at least 10 minutes after adding

stabilizer to allow the stabilizer to reach the carburetor. Do

not drain the gas tank and carburetor if using fuel stabilizer.
