hours of operation.
• Wheel hardware must be tightened to specified torque
using the proper procedure anytime it is loosened.
Driving Safely on Public Roads
Avoid personal injury or death resulting from a collision with
another vehicle on public roads:
• Use safety lights and devices. Slow moving machines
when driven on public roads are hard to see, especially at
night.
• Use extra care when loading or unloading the machine
into a trailer or truck.
• Whenever driving on public roads, use flashing warning
lights and turn signals according to local regulations. Extra
flashing warning lights may need to be installed.

SAFETY
damage and vibration. Check connections regularly.
Tighten loose connections.
• Escaping fluid under pressure can penetrate the skin
causing serious injury. Avoid the hazard by relieving
pressure before disconnecting hydraulic or other lines.
Tighten all connections before applying pressure.
• Search for leaks with a piece of cardboard. Protect
hands and body from high pressure fluids.
• If an accident occurs, see a doctor immediately. Any
fluid injected into the skin must be surgically removed
within a few hours or gangrene may result. Doctors
unfamiliar with this type of injury should reference a
knowledgeable medical source.
Prevent Fires
• Never remove fuel cap, or add fuel with engine running
or hot. Allow engine to cool for several minutes.
• Never store equipment with fuel in the tank inside a
building where fumes may reach an open flame or spark.
• Allow engine to cool before storing in any enclosure.

running.
• Never fill fuel tank or drain fuel from a machine in an
enclosed area. Fill fuel tank outdoors.
• Prevent fires. Clean up spilled fuel immediately.
• Do not store machine with fuel in tank in a building
where fumes may reach an open flame or spark.
• Prevent fire and explosion caused by static electric
discharge. Use only non-metal, portable fuel containers
approved by the Underwriter’s Laboratory (U.L.) or the
American Society for Testing & Materials (ASTM). If using
a funnel, make sure it is plastic and has no screen or filter.
Tire Safety
Explosive separation of a tire and rim parts can cause
serious injury or death:
• Do not attempt to mount a tire without the proper
equipment and experience to perform the job.
• Always maintain the correct tire pressure. Do not inflate
the tires above the recommended pressure. Never weld or
heat a wheel and tire assembly. The heat can cause an
increase in air pressure resulting in a tire explosion.
Welding can structurally weaken or deform the wheel.
• When inflating tires, use a clip-on chuck and extension
hose long enough to allow you to stand to one side and not
in front of or over the tire assembly.
• Check tires for low pressure, cuts, bubbles, damaged
rims or missing lug bolts and nuts.
Handling Fuel Safely
Fuel and fuel vapors are highly flammable and explosive:
• Do not refuel machine while you smoke, when machine
is near an open flame or sparks, or when engine is running.
Stop engine and allow to cool before filling.
• Never remove the fuel cap or add fuel with the engine
MIF
• Static electric discharge can ignite gasoline vapors in an
ungrounded fuel container. Remove the fuel container from
the bed of a vehicle or the trunk of a car and place on the
ground away from the vehicle before filling. Keep nozzle in
contact with container opening while filling.
• When practical, remove equipment from trailers or truck
beds and refuel them on the ground. If this is not possible,
use a portable, plastic fuel container to refuel equipment on
a truck bed or trailer.
• For gasoline engines, do not use gas with methanol.
Methanol is harmful to your health and to the environment.

STORAGE
Storage
Storing Safety
c CAUTION: Avoid injury! Fuel vapors are
explosive and flammable. Engine exhaust
fumes contain carbon monoxide and can cause
serious illness or death:
• Run the engine only long enough to move
the machine to or from storage.
• Do not store vehicle with fuel in the tank
inside a building where fumes may reach an
open flame or spark.
• Allow the engine to cool before storing the
machine in any enclosure.
Preparing Machine for Storage
1. Repair any worn or damaged parts. Replace parts if
necessary. Tighten loose hardware.
2. Repair scratched or chipped metal surfaces to prevent
rust.
3. Clean under the deck and remove grass and debris
from inside chute and bagger.
4. Wash the machine and apply wax to metal and plastic
surfaces.
5. Run machine for five minutes to dry belts and pulleys.
6. Apply light coat of engine oil to pivot and wear points to
prevent rust.
circulate through carburetor.

not to be used for longer than 60 days.
1. Change engine oil and filter while engine is warm.
2. Service air filter if necessary.
3. Clean debris from engine air intake screen.
4. Remove spark plugs. Put 30 mL (1 oz.) of clean engine
oil in cylinders.
5. Crank the engine five or six times to allow oil to be
distributed.
6. Install spark plugs.
7. Clean the engine and engine compartment.
8. Remove battery.
9. Clean the battery and battery posts. Check the
electrolyte level.
10.Move fuel shut-off valve to off position.
11.Store the battery in a cool, dry place where it will not
freeze.
NOTE: The stored battery should be recharged every
90 days.
12.Charge the battery.
13.Store the vehicle in a dry, protected place. If vehicle is
stored outside, put a waterproof cover over it.
Preparing Fuel and Engine for Storage
Fuel:
If you have been using “Stabilized Fuel”, add stabilized fuel
to tank until the tank is full.
NOTE: Filling the fuel tank reduces the amount of air in
the fuel tank and helps reduce deterioration of fuel.
If you are not using “Stabilized Fuel”:
1. Park machine safely in a well-ventilated area.
NOTE: Try to anticipate the last time the machine will
be used for the season so very little fuel is left in the
fuel tank.
2. Turn on engine and allow to run until it runs out of fuel.
3. Turn key to off position.
4. Mix fresh fuel and fuel stabilizer in separate container.
Follow stabilizer instructions for mixing.
5. Fill fuel tank with stabilized fuel.
6. Run engine for a few minutes to allow fuel mixture to
Removing Machine From Storage
1. Check tire pressure.
2. Check engine oil level.
3. Check battery electrolyte level. Charge battery if
necessary.
4. Install battery.
5. Check spark plug gap. Install and tighten plugs to
specified torque.
6. Lubricate all grease points.
7. Turn fuel shut-off valve to on position.
8. Run the engine 5 minutes without the mower or any
attachments running to allow oil to be distributed
throughout engine.
9. Be sure all shields and guards or deflectors are in place.

in small parts bag.
2. Connect seat safety switch to wiring harness.
3. Install handles on control levers and secure using
sleeves, cap screws and nuts provided in small parts bag.
Activate and Charge Battery
c CAUTION: Avoid injury! Battery electrolyte
contains sulfuric acid. It is poisonous and can
cause serious burns:
• Wear eye protection and gloves.
• Keep skin protected.
• If electrolyte is swallowed, get medical
attention immediately.
• If electrolyte is splashed into eyes, flush
immediately with water for 15-30 minutes and
get medical attention.
• If electrolyte is splashed onto skin, flush
immediately with water and get medical
attention if necessary.
1. Park the vehicle safely. (See Parking Safely in the
Safety section.)
2. Remove battery from machine and set it on a level
surface.
3. Remove battery cell caps. Make sure cap vents are not
plugged.
be 6 mm (1/4 in.) above plates (B), but NO HIGHER
than 6 mm (1/4 in.) from the bottom of the filler neck (C).
5. Install the battery caps before charging the battery.
IMPORTANT: Avoid damage! Wait 20 minutes before
charging the battery to allow the plates to “absorb”
the acid, so they will take a charge well.
Battery must be charged before operation. Adding
acid without charging will result in battery damage.
6. Charge the battery for a minimum of 30 minutes at 5-10
amps. If your battery charger has a Deep Cycle or
Maintenance Free setting, use this setting to charge the
battery. Failure to charge the battery before use will reduce
battery performance and life.
7. Install the battery in the machine.
Check Fluid Levels
IMPORTANT: Avoid damage! Check all fluid levels
before attempting to start the machine. Machine
should be parked on a hard, level surface with the
key switch in the STOP position.
Check Engine Oil Level
Oil level should be between the ADD and FULL marks on
the dipstick. Add oil as necessary.
Check Transmission Oil Level
Hydraulic oil level should be to the top of the FULL COLD
mark on the reservoir dipstick. Add oil as necessary.
If your mower has no dipstick, make sure that oil is 76 mm
(3 in.) from the top of the filler pipe.

Check Tire Pressure
c CAUTION: Avoid injury! Explosive separation
of tire and rim parts is possible when they are
serviced incorrectly:
• Do not inflate the tires above the
recommended pressure.
• Do not stand in front or over the tire
assembly when inflating. Use a clip-on chuck
and extension hose long enough to allow you
to stand to one side.
1. Check tires for damage.
2. Check tire pressure with an accurate gauge.
3. Check that tires have equal pressure; add or remove air,
if necessary.
Tire Size Pressure
Front: 13 x 5.0 - 6 110-139 kPa (16-20 psi)
Rear: 23 x 9.5- 12 69-83 kPa (10-12 psi)
c CAUTION: Avoid injury! Engine exhaust fumes
contain carbon monoxide and can cause
serious illness or death.
Move the vehicle to an outside area before
running the engine.
Do not run an engine in an enclosed area
without adequate ventilation.
• Connect a pipe extension to the engine
exhaust pipe to direct the exhaust fumes out of
the area.
• Allow fresh outside air into the work area to
clear the exhaust fumes out.
3. Start and run the engine until it reaches normal
operating temperature.
4. Move control levers to the forward position and observe
drive wheel rotation; the drive wheels should rotate in the
correct direction.
5. Move the control levers to the reverse position and
observe drive wheel rotation; the drive wheels should
rotate in the correct direction.
Level Mower Deck
Before operating the machine, level the mower deck.
Initial Adjustments
c CAUTION: Avoid injury! Clear area of
bystanders before performing this service
procedure.
1. Check free-wheeling valves on both pump assemblies
to make sure that the valves are closed.
2. Raise the rear of the machine until the drive wheels are
off the ground. Support the machine with jackstands.
NOTE: Neutral position and transmission linkage
adjustments will needed to be recheck after several
hours of operation.
6. Release control levers; the levers should return to the
neutral position and wheel rotation should stop. If the
wheels do not stop, adjust the neutral adjustment knob on
each side of the seat.
7. Move PTO/clutch switch to on position; mower clutch
should engage. Run blades for several minutes.
8. Move PTO/clutch switch to off position and shut the
engine off.
9. Check all belts for proper tension.
10.Start the engine and test drive the machine in an open
area. Drive the machine forward; if the machine drifts to the
right or left, adjust the transmission control linkage.
