Repair, if necessary, before restarting.
Never make adjustments or repairs with the engine running.
Grass catcher components are subject to wear, damage, and
deterioration, which could expose moving parts or allow
objects to be thrown. Frequently check components and
replace with manufacturer's recommended parts, when nec o
essary.

MOWING
Fill fuel tank. Use fresh, clean, regular unleaded
gasoline. (Use of leaded gasoline will increase carbon

iMPORTANT: WHEN OPERATING IN TEMPERATURES
BELOW 32°F(0°C), USE FRESH, CLEAN WINTER GRADE
GASOLINE TO HELP iNSURE GOOD COLD WEATHER
STARTING.
Tire chains cannot be used when the mower housing
is attached to unit.
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 fue! system should be emptied before storage of 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 charier products in the fuel tank or permanent
damage may occur.
ENGINE
Mower should be properly leveled for best mowing
performance. See "TO LEVEL MOWER HOUSING" in
the Service and Adjustments section of this manual.
-
Use the runner on the right hand side of mower as a
guide. The blade cuts approximately an inch outside
the runner (See Fig. 10).
The left hand side of mower should be used for trimming.
o
•
If grass is extremely tall, it should be mowed twice to
reduce load and possible fire hazard from dried clippings. Make first cut relatively high; the second to the
desired height.
o
Do not mow grass when it is wet. Wet grass will plug
mower and leave undesirable clumps. Allow grass to
dry before mowing.
o
Always operate engine at full throttle when mowing to
assure better mowing performance and proper discharge of material. Regulate ground speed by selecting a low enough gear to give the mower cutting
performance as well as the quaIity of cut desired.
o
When operating attachments, select a ground speed
that will suit the terrain and give best performance of
the attachment being used.

o
Drive so that clippings are discharged onto the area
that has been cut. Have the cut area: to the right of the
machine. This wilt result in a more even distribution of
clippings and more uniform cutting.
When mowing large areas, start by turning to the right
so that clippings will discharge away from shrubs,
fences, driveways, etco After one or two rounds, mow
in the opposite direction making left hand turns until
finished (See Fig. 12).
When starting engine for the first time or if engine has run

The fue! filter should be replaced once each season. If fuel
filter becomes clogged, obstructing fuel flow to carburetor,
replacement is required.
o With engine cool, remove filter and plug fuel line
sections.

Remove mower from tractor for winter storage
When
mower is to be stored for a period of time. clean it thoroughly, remove all dirt, grease, leaves, etc. Store in a
clean, dry area.
-
Clean entire tractor (See "CLEANING" in the Customer
Responsibilities section of this manual).
o
Inspect and replace belts, if necessary (See belt replacement instructions in the Service and Adjustments
section of this manual).
Q
e
Be sure that all nuts, bolts and screws are securely
fastened. Inspect moving parts for damage, breakage
and wear. Replace if necessary.
o
Touch up all rusted or chipped paint surfaces: sand
lightly before painting.
NOTE: Fuel stabilizer is an acceptable alternative in
minimizing the formation of fuel gum deposits during storage. 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.
ENGINE
Fully charge the battery for storage.
o
After a period of time in storage, battery may require
recharging.
-
To help prevent corrosion and power leakage during
long periods of storage, battery cables should be
disconnected and battery cleaned tho roughly (see "TO
CLEAN BATTERY AND TERMINALS" in the Customer Responsibilities section of this manua ).
-
CYUNDERS
After cleaning, leave cables disconnected and place
cables where they cannot come Jncontact with battery
terminals.
®
Be sure battery drain tube is securely attached.
o
If battery is removed from tractor for storage, do not
store battery directly on concrete or damp surfaces.
OIL
Drain oil (with engine warm) and replace with clean engtne
oil. (See "ENGINE" in the Customer Responsibilities
section of this manuab.
BATTERY
-
Start the engine and tet it run until the fuel lines and
carburetor are empty.
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage may occur.
Use fresh fuel next season.
Lubricate as shown in the Customer Responsibilities
section of this manual.
o
Drain the fuel tank.
o
Remove spark plug(s).
,
Pour one ounce of oil through spark plug hole(s) into
cylinder(s).
•
Turn ignition key to"START" position for a few seconds
to distribute oil.
o
Replace with new spark plug(s).
OTHER
o
Do not store gasoline from one season to another.
Replace your gasoline can if your can starts to rust.
Rust and/or dirt in your gasoline will cause problems
o
o
If possible, store your tractor indoors and cover it to
give protection from dust and dirt.
Cover your tractor with a suitable protective cover that
does not retain moisture Do not use plastic. Plastic
cannot breathe which allows condensation to form and
will cause your tractor to rust.
