Operation
Adding Fuel
•
For best results, use only clean, fresh, unleaded gasoline
with an octane rating of 87 or higher ((R+M)/2 rating
method).
•
Oxygenated fuel with up to 10% ethanol or 15% MTBE
by volume is acceptable.
•
Ethanol: Gasoline with up to 10% ethanol (gasohol)
or 15% MTBE (methyl tertiary butyl ether) by volume
is acceptable. Ethanol and MTBE are not the same.
Gasoline with 15% ethanol (E15) by volume is not
approved for use. Never use gasoline that contains
more than 10% ethanol by volume, such as E15
(contains 15% ethanol), E20 (contains 20% ethanol), or
E85 (contains up to 85% ethanol ). Using unapproved
gasoline may cause performance problems and/or engine
damage which may not be covered under warranty.
•
Do not use ethanol blends of gasoline (such as E15
or E85) with more than 10% ethanol by volume.
Performance problems and/or engine damage may result
which may not be covered under warranty.
•
Do not use gasoline containing methanol.
•
Do not store fuel either in the fuel tank or fuel containers
over the winter unless a fuel stabilizer is used.
•
Do not add oil to gasoline.
DANGER
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or explosion
from gasoline can burn you and others and can
damage property.
•
Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any gasoline
that spills.
•
Never fill the fuel tank inside an enclosed trailer.
•
Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 6 to 13
mm (1/4 to 1/2 inch) below the bottom of the
filler neck. This empty space in the tank allows
gasoline to expand.
•
Never smoke when handling gasoline, and stay
away from an open flame or where gasoline
fumes may be ignited by a spark.
•
Store gasoline in an approved container and
keep it out of the reach of children. Never buy
more than a 30-day supply of gasoline.
•
Do not operate without entire exhaust system in
place and in proper working condition.
11
In certain conditions during fueling, static
electricity can be released causing a spark which
can ignite the gasoline vapors. A fire or explosion
from gasoline can burn you and others and can
damage property.
•
Always place gasoline containers on the ground
away from your vehicle before filling.
•
Do not fill gasoline containers inside a vehicle or
on a truck or trailer bed because interior carpets
or plastic truck bed liners may insulate the
container and slow the loss of any static charge.
•
When practical, remove gas-powered equipment
from the truck or trailer and refuel the equipment
with its wheels on the ground.
•
If this is not possible, then refuel such
equipment on a truck or trailer from a portable
container, rather than from a gasoline dispenser
nozzle.
•
If a gasoline dispenser nozzle must be used,
keep the nozzle in contact with the rim of the
fuel tank or container opening at all times until
fueling is complete.
WARNING
Gasoline is harmful or fatal if swallowed. Long-term
exposure to vapors can cause serious injury and
illness.
•
Avoid prolonged breathing of vapors.
•
Keep face away from nozzle and gas tank or
conditioner opening.
•
Keep gas away from eyes and skin.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the machine to provide
the following benefits:
•
Keeps gasoline fresh during storage of 90 days or less.
For longer storage it is recommended that the fuel tank
be drained.
•
Cleans the engine while it runs
•
Eliminates gum-like varnish buildup in the fuel system,
which causes hard starting
Important: Do not use fuel additives containing
methanol or ethanol.
Add the correct amount of gas stabilizer/conditioner to the
gas.
Note: A fuel stabilizer/conditioner is most effective when
mixed with fresh gasoline. To minimize the chance of varnish
deposits in the fuel system, use fuel stabilizer at all times.
Filling the Fuel Tank
1.
Shut the engine off and set the parking brake.
2.
Clean around each fuel tank cap and remove the cap.
3.
Add unleaded regular gasoline to both fuel tanks, until
the level is 6 to 13 mm (1/4 to 1/2 inch) below the
bottom of the filler neck.
This space in the tank allows gasoline to expand. Do
not fill the fuel tanks completely full.
4.
Install fuel tank caps securely.
5.
Wipe up any gasoline that may have spilled.
Checking the Engine-Oil Level
Before you start the engine and use the machine, check the oil
level in the engine crankcase; refer to Checking Oil Level in
Engine Maintenance (page 21).
Note: Determine the left and right sides of the machine
from the normal operating position.

Adjusting the Height-of-Cut
The height-of-cut can be adjusted from 25 to 114 mm (1
to 4-1/2 inch) in 6 mm (1/4 inch) increments. Adjustment
is done by relocating 4 hairpin cotter pins in different hole
location and by adding or removing spacers.
Note: All height-of-cut pins need at least 1 spacer or damage
can occur to bushing if none are used.
Note: All height-of-cut pins can use 2 spacers maximum.
1.
Select hole in height-of-cut post and number of spacers
corresponding to the height-of-cut desired (Figure 12).
2.
Using the lift handle, raise side of deck and remove
hairpin cotter (Figure 12).
3.
Add or remove spacers if needed and then align holes
and insert hairpin cotter (Figure 12).
Note: Spare height-of-cut spacers may be stored on
posts and retained by a hairpin cotter.
Important: All 4 hairpin cotter pins must be in the
same hole location and with the correct number of
spacers for a level cut.

Adjusting the Anti-Scalp
Rollers
The anti-scalp rollers need to be adjusted in the proper hole
location for each height-of-cut position. There needs to be 10
mm (3/8 inch) minimum clearance above the ground.
Note: If the anti-scalp rollers are adjusted too low it can
cause excess wear of the rollers.
1.
After adjusting height-of-cut, check the anti-scalp
rollers so that there is a minimum of 10 mm (3/8 inch)
clearance above the ground (Figure 13).
2.
If adjustment is needed, remove the bolt, washers and
nut (Figure 13).
3.
Select a hole position so the anti-scalp rollers are a
minimum of 10 mm (3/8 inch) off the ground (Figure
13).
