SAFE OPERATION

Careful operation is your best insurance against an
accident. The owner/user can prevent and is responsible
for accidents or injuries occurring to themselves, other
people or property. Read and understand this manual
carefully before operating the machine. All operators, no
matter how much experience they may have had, must
read this and other related manuals before operating the
machine or any implement attached to it. It is the owner's
obligation to instruct all operators in safe operation.
If the operator(s) or mechanic(s) cannot read English it is
the owner's responsibility to explain this material to them.
This mowing machine is capable of amputating hands and
feet and throwing objects. Failure to observe the following
safety instructions could result in serious injury or death.

1. BEFORE OPERATING

1. The ZERO TURN MOWING MACHINE has different
steering characteristics than other machines with a
steering wheel and does not have a service brake
pedal (but, has a parking brake lock pedal that can be
used to stop the machine in an emergency. Normal
slowing down and stopping is done with the motion
control levers.). Read and understand the operators
manual before operating the machine. Practice
operating machine at low engine speed without mower
engaged in an unobstructed area.

2. Know your equipment and its limitations. Read all
instructions in this manual before attempting to start
and operate the machine.

3. Pay special attention to the danger, warning and
caution labels on the machine itself.

-1SAFE OPERATION

ENGLISH

4. The ROPS is an integral and effective safety device.
KUBOTA recommends the use of a Roll Over
Protective Structures (ROPS) and seat belt in almost
all applications. This combination will reduce the risk
of serious injury or death, should the machine be
upset.
The machine is equipped with a Foldable ROPS,
which may be temporarily folded down only when
absolutely necessary for areas with height constraints.
There is no operator protection provided by the ROPS
in the folded position. For operator safety you must set
the ROPS in the upright and locked position and put on
the seat belt for all other operations.
DO NOT remove the ROPS.
If the ROPS is loosened or removed for any reason,
make sure that all parts are reinstalled correctly before
operating the machine.
Never modify or repair a ROPS because welding,
bending, drilling, grinding, or cutting may weaken the
structure.
If any structural member of the ROPS is damaged,
replace the entire structure at your local KUBOTA
Dealer. Any alterations to a ROPS must be approved
by the manufacturer.
Check the area to be mowed and never fold down a
folding ROPS in areas where there are slopes, drop
offs or water.
Check carefully for overhead clearances (i.e.
branches, doorways, electrical wires) before driving
under any objects and do not contact them.
Keep the ROPS in safe operating condition by
periodically thoroughly inspecting for damage and
keeping all mounting fasteners tight.

(1) ROPS
(2) Seat belt

SAFE OPERATION-2

5. Always use the seat belt when the ROPS is upright. Do
not use the seat belt if the ROPS is down or if there is
no ROPS. Check the seat belt regularly and replace if

ENGLISH

frayed or damaged. Be certain that the seat belt can be
released quickly in the event of an emergency.

6. Do not operate the machine or any attachments while
under the influence of alcohol, medication, controlled
substances or when fatigued.

7. Do not wear loose, torn, or bulky clothing around
machine. The clothing may catch on moving parts or
controls, leading to the risk of accident. Wear and use
any additional safety items such as hard hat, safety
boots or shoes, eye and hearing protection, gloves,
etc., as appropriate or required.

8. Do not wear radio or music headphones while
operating the machine.
Safe operation requires your full attention.

9. Carefully check the vicinity before operating machine
or any implement attached to it. Clear the work area of
objects (wires, rocks, etc.) that might be picked up and
thrown. Check for overhead clearance which may
interfere with a grass catcher.

10.Check brakes and other mechanical parts for correct
adjustment and wear. Replace worn or damaged parts
promptly. Check the tightness of all nuts and bolts
regularly. (For further details, see "PERIODIC
SERVICE" and "ADJUSTMENT" section.)

11.Keep all shields and guards in place. Replace any that
are damaged or missing. Do not operate unless they
are functioning properly.

12.Before allowing other people to use your machine,
explain how to operate and have them read this
manual before operation.

13.Do not allow any bystanders around or near machine
during operation.

14.Do not allow passengers, children or non-qualified
operators on the machine at any time. The operator
must remain in the machine seat throughout
operation.

15.In addition to the design and configuration of
equipment, hazard control and accident prevention
are dependent upon the awareness, concern, and
prudence of personnel involved in the operation,
transport, maintenance of facilities.

16.Evaluate the terrain to determine what accessories
and attachments are needed to properly and safely
perform the job. Keep the machine and attachments in
good operating condition and keep safety devices in
place and in proper working condition. Do not operate
unless they are functioning properly.

17.Do not modify the machine. Unauthorized modification
may affect the function of the machine, which may
result in personal injury.

18.Use only implements recommended by KUBOTA. Use
proper ballast to front or rear of machine to reduce the
risk of upsets. Follow the "SAFE OPERATION"
procedures, specified in the manuals with equipment.

19.Keep your machine clean. Accumulations of dirt,
grease, and trash can contribute to fires and lead to
personal injury.

20.The exhaust gas from the muffler is very hot. To
prevent fire, do not expose dry grass, mowed grass, oil
and any other combustible materials to exhaust gas.
Use a spark arrester where required. Also keep the
engine and muffler clean all the time.

2. OPERATING

C Starting

1. Always sit in the operator's seat when starting engine
or operating levers or controls.

2. Before starting the engine make sure that the motion
control levers are in neutral lock, the parking brake is
applied, and Power Take Off (PTO) is disengaged
(OFF).

3. Do not start engine by shorting across starter
terminals. The machine may start in gear and move if
normal starting circuitry is bypassed.

4. Do not operate or idle engine in a non-ventilated area.
Carbon monoxide gas is colorless, odorless, and
deadly.

C Working

1. Do not turn sharply when driving at high speed.

2. To avoid tip over, slow down when turning on uneven
terrain or before stopping.

3. Do not operate near ditches, holes, embankments, or
other terrain, which may collapse under the machine
weight. The risk of machine tip over increases when
the ground is loose or wet.

4. Park the machine on a firm and level surface.

5. Watch where you are going at all times. Watch for and
avoid obstacles. Be alert at curbs, shrubs, near trees,
and other obstructions and hidden hazards. Obstacles
can damage machine (fuel hoses, wire harness etc.).

6. Know what is behind you before backing up. Look to
the rear before and when backing. Do not mow while
in reverse unless absolutely necessary and make sure
the area immediately behind you is clear of
obstructions or holes and small children. Use extra
caution when machine is equipped with Grass
Catcher. Your view to the rear is restricted.

7. When working in groups, always let others know what
you are doing ahead of time.

8. Do not drive machine on streets or highways. Watch
for traffic when you cross roads or operate near roads.

9. Be aware of the mower discharge direction and do not
point it at anyone.
Never operate with the discharge deflector raised,
removed or altered, unless using a grass catcher.

-3SAFE OPERATION

10.When using any attachments, never direct discharge
material toward bystanders. Do not allow anyone and
pets near the attachments while in operation.
Do not mow when bystanders are present in the
mowing area.

11.To reduce fire hazards, keep the engine exhaust area
free of grass or leaves.

12.Be sure rotating blades and engine are stopped and
the key is removed before placing hands or feet near
blades and cleaning blockages or unclogging chute.

13.Keep hands and feet away from the cutting units. Shut
the engine off and wait for all movement to stop before
removing grass catcher or unclogging chute.

14.Always inspect the mower for damage after striking a
foreign object. Repair or replace any damaged parts
before restarting.

15.Operate during daylight or in bright artificial light.

16.If the machine starts to vibrate abnormally, disengage
the drive to the attachments, stop the engine and
remove the key. Then check the machine immediately.

17.Do not operate the machine when there is a possibility
of lightning. Even if the machine is equipped with a
cabin, the operator is not protected from lightning.

18.Never raise the deck with the blades running.
Stop blades if not mowing.

a) Pull only from the hitch. Never attach loads to the axle
housing or any other point above hitch.
b) Limit loads to those you can safely control.
c) Do not turn sharply.
d) Use care when backing.
e) Use front ballast or wheel weights when suggested in
this Operator's Manual.
A Stopping distance increases with speed and weight of

towed load. Travel slowly and allow extra time and
distance to stop.

A Never allow children or others in or on towed

equipment.

A Use additional caution when turning or operating

under adverse surface conditions.

C Operation on slopes

Slopes are major factor related to loss-of-control and tip­over accidents, which can result in severe injury or death.
All slopes require extra caution.
If you cannot back up the slope or if you feel uneasy on it,
do not mow it.
If the engine stops when operating on a slope apply the
parking brake immediately to prevent machine run away.

ENGLISH

C Children

Tragic accidents can occur if the operator is not alert to
the presence of children. Children are attracted to the
machine and mowing activity.
Never assume that children will remain where you last
saw them.

1. Keep children out of the mowing area and under the
watchful care of another responsible adult.

2. Be alert and turn machine off if children enter the area.

3. Before and when backing, look behind and down for
small children.

4. Never carry children. They may fall off and be
seriously injured or interfere with safe machine
operation.

5. Never allow children to operate the machine, even
under adult supervision. Local regulation can restrict
the age of the operator.

6. Use extra care when approaching blind corners,
shrubs, trees, or other obstructions that might hide
children from sight.

7. Do not mow in reverse unless it is absolutely
necessary.

C Operators, age 60 years and above

Data indicates that operators, age 60 years and above,
are involved in a large percentage of machine-related
injuries. These operators must evaluate their ability to
operate the machine safely enough to protect themselves
and others from serious injury.

C Pulling loads

Use extra care when pulling loads to reduce the risk of
serious personal injury or death due to a machine tip-over.

DO

1. To avoid tip over, operate across the slopes not up and
down. Stay off hills and slopes too steep for safe
operation.

2. Remove obstacles such as rocks, tree limbs, etc.

3. Stay alert for holes in the terrain and other hidden
hazards. Keep away from drop-offs. Uneven terrain
could overturn the machine. Tall grass can hide
obstacles.

4. Follow the manufacturer's recommendations for wheel
weight or counterweights to improve stability.

5. Keep all movement on the slopes slow and gradual.
Do not make sudden changes in speed or direction.
If tires lose traction, disengage PTO and proceed
slowly straight down the slope.

6. Reduce speed and exercise extreme caution on
slopes and in sharp turns to prevent tip-over or loss of
control.

SAFE OPERATION-4

7. Use special caution when changing direction on
slopes. Slow down, and use extra caution when
changing direction on a slope.

ENGLISH

DO NOT

1. Do not turn on slopes unless necessary. If necessary,
turn uphill slowly and gradually.

2. Do not mow near drop-offs, ditches, or embankments.
The mower could suddenly turn over if a wheel is over
the edge of cliff or ditch, or if an edge caves in.

3. Do not mow on wet grass. Reduced traction could
cause sliding and loss of control.

4. Do not try to stabilize the machine by putting your foot
on the ground.

5. Do not use grass catcher on steep slopes.

6. Do not start or stop suddenly on slopes. If tires lose
traction, disengage PTO and proceed slowly straight
down the slope.

7. Never "freewheel". Do not let the machine travel
downhill with motion control levers at neutral lock
position or in neutral.

8. Do not operate machine without the mower deck
installed.

C Stopping

1. Park the machine on level ground.

2. Make sure that the machine and all attachments have
come to a complete stop before you get off.

3. Before you get off, apply parking brake, place the
motion control levers in their neutral lock positions,
disengage the PTO, lower all attachments to the
ground, turn off the engine, and remove the key.

4. Do not park the machine on dry grass or leaves.

5. TRANSPORTING

1. Disengage power to attachment(s) when transporting
or not in use.

2. Do not tow this machine. Use a suitable truck or trailer
when transporting on public roads.

3. Use extra care when loading or unloading the machine
into a trailer or truck. Use full width ramps for loading
machine into trailer or truck.

4. This machine is not allowed to be used on public
roads.

5. Shut off fuel while storing or transporting.

6. Tie the machine down securely using straps, chains,
cable, or ropes.

7. Both front and rear straps must be directed down and
outward from the machine.

6. SERVICING AND STORAGE

C Servicing

1. Before servicing, park the machine on a firm, level
surface and apply the parking brake. Remove the key
to prevent accidental start-up.

2. Allow the machine time to cool before touching the
engine, muffler, radiator, etc.

3. Always stop the engine before refueling. Avoid spills
and overfilling. Wipe up spilled fuel immediately.

3. USING THE PTO

1. Before installing or using PTO-driven equipment, read
the manufacturer's manual and review the safety
labels attached to the equipment.

2. Wait until all moving components have completely
stopped before connecting, disconnecting, adjusting,
cleaning, or servicing any PTO-driven equipment.

3. Use the PTO with KUBOTA approved attachments.

The speed of PTO:
ZD1011 / ZD1021 Without mower: 2450 to 2550 rpm at
3200 engine rpm

4. USING THE LIFT LINK

1. Use lift link only with authorized attachments designed
for lift link usage.

(1) Fuel tank cap

4. Use extra care in handling diesel fuels. They are
flammable.
(1) Use only an approved container.
(2) Do not remove fuel cap or refuel with the engine

running. Allow engine to cool before refueling. Do
not smoke while refueling or when standing near
fuel.

(3) Do not refuel the machine indoors and always

clean up spilled fuel or oil.

(4) Do not store the machine or fuel container inside

where there is an open flame, such as in a water
heater.

5. Do not smoke when working around battery or when
refueling. Extinguish all cigarettes, cigars, pipes, and
other sources of ignition. Keep all sparks and flames
away from battery and fuel tank.

Never fill containers inside a vehicle or on a truck or
trailer bed with a plastic liner.
Always place containers on the ground away from
your vehicle before filling.
Remove equipment from the truck or trailer and refuel
it on the ground.
If this is not possible, then refuel such equipment with
a portable container, rather than from a fuel dispenser
nozzle.
Keep the nozzle in contact with the rim of the fuel tank
or container opening at all times until fueling is
complete.
Do not use a nozzle lock open device.
If fuel is spilled on clothing, change clothing
immediately.
Replace fuel cap and tighten securely.
Charge batteries in an open well ventilated area, away
from spark and flames.
A battery, especially when charging, will give off
hydrogen and oxygen gases, which can explode and
cause serious personal injury.
Unplug charger before connecting or disconnecting
from battery.

6. Before "jump starting" a dead battery, read and follow
all the instructions.

7. Disconnect battery or remove spark plug wire before
making any repairs. Disconnect the negative terminal
first and the positive last. Reconnect positive first and
negative last. Wear protective clothing and use
insulated tools.

-5SAFE OPERATION

(1) Battery
(2) Ground cable

(+): Positive terminal
(-): Negative terminal

8. Do not use or charge the refillable type battery if the
fluid level is below the LOWER (lower limit level) mark.
Otherwise, the battery component parts may
prematurely deteriorate, which may shorten the
battery's service life or cause an explosion. Check the
fluid level regularly and add distilled water as required
so that the fluid level is between the UPPER and
LOWER levels.

9. Keep first aid kit and fire extinguisher handy at all
times.

ENGLISH

SAFE OPERATION-6

10.Do not remove the radiator cap while coolant is hot.
When cool, slowly rotate cap to the first stop and allow
sufficient time for excess pressure to escape before

ENGLISH

removing the cap completely. If the machine has a
coolant recovery tank, add coolant there instead of the
radiator.

11.Do not attempt to mount a tire on a rim unless qualified
to do so and all proper safety precautions are followed.
Never allow untrained personnel to service machine.

12.Always maintain the correct tire inflation pressure. Do
not inflate tires above the recommended pressure
shown in the Operator's Manual.

16.Fluid escaping from pinholes may be invisible. Use a
piece of cardboard or wood to search for suspected
leaks: do not use hands. Use safety goggles or other
eye protection.
If you get injured by escaping fluid, see a medical
doctor at once. Serious infection or reaction will result
if proper medical treatment is not administered
immediately. This fluid can produce gangrene or
severe allergic reaction.

(1) Cardboard
(2) Hydraulic line
(3) Magnifying glass

13.Provide adequate support when changing wheels.

14.Make sure that wheel nuts and bolts have been
tightened to the specified torque.

15.Escaping hydraulic fluid under pressure has sufficient
force to penetrate the skin causing serious personal
injury. Before disconnecting lines, be sure to relieve all
pressure. Before applying pressure to the system,

OPERATING THE ENGINE16

WARMING UP

ENGLISH

To avoid serious injury or death:
A Be sure to apply the parking brake during

warm-up.

For 5 minutes after engine start-up, allow the engine to
warm up without applying any load. This is to allow oil to
reach every engine part. If load should be applied to the
engine without this warm-up period, the troubles such as
seizure, breakage or premature wear may develop.

BWarm-up and Transmission Oil in the Low

Temperature Range

Hydraulic oil serves as transmission oil. In cold weather,
the oil may be cold with increased viscosity. This can
cause delayed oil circulation or abnormally low hydraulic
pressure for some time after engine start-up. This in turn
can result in a trouble in the hydraulic system or a damage
to the hydraulic clutch.
To prevent the above, observe the following instructions:
Warm up the engine at about 50% of rated rpm according
to the table below:

Ambient temperature Warm-up time requirement

Higher than 0 (32 ) Approx. 5 minutes

-10 to 0 (14 to 32 ) 5 to 10 minutes

-20 to -10 (-4 to 14 ) 10 to 15 minutes

Below -20 (-4 ) More than 15 minutes

JUMP STARTING

To avoid serious injury or death:
A Battery gases can explode. Keep cigarettes,

sparks, and flames away from battery.

A If the machine battery is frozen, do not jump

start the engine.

A Do not connect the other end of negative

jumper cable to the negative terminal of the
machine battery.

When jump starting the engine, follow the instructions
below to start the engine safely.

1. Bring a helper vehicle with a battery of the same
voltage as the disabled machine within easy cable
reach. "THE VEHICLES MUST NOT TOUCH".

2. Apply the parking brakes of both vehicles and put the
shift levers in neutral. Shut the engine off.

3. Put on safety goggles and rubber gloves.

4. Ensure vent caps are securely in place (if equipped).

5. Attach the red clamp to the positive (red, (+) or pos.)
terminal of the dead battery and clamp the other end
of the same cable to the positive (red, (+) or pos.)
terminal of the helper battery.

6. Clamp the other cable to the negative (black, (-) or
neg.) terminal of the helper battery.

7. Clamp the other end to the engine block or the frame
of the disabled machine as far from the dead battery
as possible.

8. Start the helper vehicle and let its engine run for a few
moments. Start the disabled machine.

9. Disconnect the jumper cables in the exact reverse
order of attachment. (Steps 7, 6 and 5)

A Do not operate unless the engine is well warmed up. If

operation is attempted while the engine is still cold, the
hydraulic mechanism will not function properly and its
service life will be shortened.

A If noises are heard after the hydraulic control lever has

been activated and the implement is lifting, the
hydraulic mechanism is not adjusted properly. Unless
corrected, the unit will be damaged. Contact your local
KUBOTA Dealer for adjustment.

(1) Dead battery
(2) Jumper cables
(3) Engine block or frame
(4) Helper battery

A This machine has a 12 volt negative (-) ground starting

system.

A Use only same voltage for jump starting.

Connect cables in numerical order.
Disconnect in reverse order after
use.

A Use of a higher voltage source on a machine could

result in severe damage to the machine electrical
system.
Use only matching voltage source when "jump­starting" a low or dead battery condition.

OPERATING THE MACHINE

OPERATING NEW MACHINE

How a new machine is operated and maintained
determines the life of the machine.
A new machine just off the factory production line has
been, of course, tested, but the various parts are not
"broken-in" and are not accustomed to each other, so care
must be taken to operate the machine for the first 50 hours
at a slower speed and avoid excessive work or operation
until the various parts become "broken-in." The manner in
which the machine is handled during the "breaking-in"
period greatly affects the life of your machine. Therefore,
to obtain the maximum performance and the longest life
of the machine, it is very important to properly break-in
your machine. In handling a new machine, the following
precautions must be observed.

BChanging Lubricating Oil for New

Machines

The lubricating oil is especially important in the case of a
new machine. The various parts are not "broken-in" and
are not accustomed to each other; small metal grit may
develop during the operation of the machine; and this may
wear out or damage the parts. Therefore, care must be
taken to change the lubricating oil a little earlier than
would ordinarily be required.
For further details of change interval hours.
(See "SERVICE INTERVALS" in "MAINTENANCE"
section.)

BEngine Break-in

After the first 50 hours of operation, change the engine oil
and filter. (See "EVERY 200 HOURS" in
"MAINTENANCE" section.)

BMachine Break-in

After the first 400 hours of operation, change the
transmission fluid. (See "EVERY 400 HOURS" in
"MAINTENANCE" section.)
After the first 50 hours of operation, change the oil filter.
(See "EVERY 200 HOURS" in "MAINTENANCE"
section.)

To avoid serious injury or death:
A Do not operate the mower without the deflector

shield in the down position.

To avoid serious injury or death:
A The machine relies upon the engine driven

transmission for speed, direction and steering
control. If the engine is not running, the
machine cannot be driven or controlled.
If the engine stops when operating on a slope,

apply the parking brake immediately to prevent
machine runaway.

A Do not allow any person other than the driver to

ride on the machine.

A Do not drive the machine close to the edges of

ditches or banks which may collapse under the
weight of the machine, especially when the
ground is loose or wet.

A When turning the machine, be sure to reduce

the travel speed and operate motion control
levers carefully.

A To avoid tip over, operate across slopes, not up

and down. Avoid sudden starts and stops on
slopes. Slow down, and use extra caution when
changing direction on a slope.
Park the machine on a firm and level surface.

A Watch where you are going at all times. Watch

for and avoid obstacles. Be alert at curbs, near
trees, and other obstructions and hidden

OPERATING THE MOWER

ENGLISH

MAKING THE MOST OF YOUR MOWER

5. For best appearance, grass must be cut in the
afternoon or evening when it is free of moisture.

To avoid serious injury or death:
A Clear the work area of objects which might be

picked up and thrown by blades.

A Keep bystanders and animals away from the

mowing area.

A Be sure to disengage the PTO and sit on the

operator's seat before starting the engine.

1. When using your mower for the first time, choose a
smooth level area and cut in straight and slightly
overlapping strips.

2. The size and type of the area to be mowed will
determine the proper mowing pattern. Take into
account obstructions, such as trees, fences and
buildings. To keep grass clippings off fences,
sidewalks, etc., it is advisable to go over the outside of
the area to be mowed several times in a clockwise
direction. To mow the area remaining, work in a
counterclockwise direction so that the clippings are
dispersed onto the previously cut area.

ADJUSTING CUTTING HEIGHT

To avoid serious injury or death:
A Do not engage the mower in the transport

position.

1. Before adjusting cutting height, check that all tire
pressures are correct. If necessary adjust to the
correct tire pressure.

(1) Lift lock lever : "LOCK"

: "UNLOCK"

3. Always keep the left side of the mower toward trees,
posts or other obstacles on the first trip around the
obstacle.

4. Most lawns must be mowed to keep the grass
approximately 50 to 80 mm (2 to 3 in.) high. Best
results are obtained by cutting often and not too short.
To keep a green lawn, never mow more than 1/3 of the
height of the grass or a maximum of 25 mm (1 in.) in 1
mowing.
For extremely tall grass, set the cutting height at
maximum cutting height for the first mowing, then
reset to the desired height and mow again. Allow the
grass to grow to 80 mm (3 in.), then cut off only the top
inch.

2. To set the cutting height, keep depressing the
hydraulic lift control pedal firmly to raise mower deck
to the top position. Make sure that the lift lock lever is
in unlock position. Adjust the cutting height control dial
to desired height.

3. Use the higher settings for mowing in a rough area or
when mowing tall grass. Lower settings must be used
only for smooth lawns where short grass is desired.

(1) Cutting height control dial
(2) Hydraulic lift control pedal

4. Lower the mower deck by releasing the hydraulic lift
control pedal. This lowers the mower deck from the
"TRANSPORT" position to the "OPERATING"
position.

5. Adjust the anti-scalp rollers' height as recommended
below for normal operating condition. To minimize
gouging and roller damage or wear, the anti-scalp
rollers will maintain the ground clearance of 19 mm (3/
4 in.).

1. To slow charge the battery, connect the battery
positive terminal to the charger positive terminal and
the negative to the negative, then charge for at least 1
hour at 4.5 amperes.

2. A boost charge is only for emergencies. It will partially
charge the battery at a high rate and in a short time.
When using a boost-charged battery, it is necessary to
recharge the battery as early as possible.
Failure to do this will shorten the battery's service life.

3. When the specific gravity of electrolyte is between

1.27 and 1.29 the charging is completed.

C Battery for storage

1. When storing the machine for a long period, remove
the battery from machine, adjust the electrolyte to the
proper level and store in a dry place out of direct
sunlight.

2. The battery self-discharges while it is stored.
Recharge it once every 3 months in hot seasons and
once every 6 months in cold seasons.

ENGLISH

To avoid serious injury or death:

A Do not clean the machine with engine running.
A To avoid the danger of exhaust fume

poisoning, do not operate the engine in a
closed building without proper ventilation.

A When storing, remove the key to avoid

unauthorized persons from operating the
machine and getting injured.

MACHINE STORAGE

If you intend to store your machine for an extended period
of time, follow the procedures outlined below. These
procedures will insure that the machine is ready to
operate with minimum preparation when it is removed
from storage,

1. Check for loose bolts and nuts, and tighten if
necessary.

2. Apply grease to machine areas where bare metal will
rust also to pivot areas.

3. Inflate the tires to a pressure a little higher than usual.

4. Change the engine oil and run the engine to circulate
oil throughout the engine block and internal moving
parts for about 5 minutes.

5. With all implements lowered to the ground, coat any
exposed hydraulic cylinder piston rods with grease.

6. Remove the battery from the machine. When
disconnecting the cables from the battery, start with
the negative terminal first. When connecting the
cables to the battery, start with the positive terminal
first.

8. Store the machine indoors in a dry area that is
protected from sunlight and excessive heat. If the
machine must be stored outdoors, cover it with a
waterproof tarpaulin.

9. Jack the machine up and place blocks under the front
and rear axles so that all 4 tires are off the ground.
Keep the tires out of direct sunlight and extreme heat.

A When washing the machine, be sure to stop the

engine. Allow sufficient time for the engine to cool
before washing.

A Cover the machine after the muffler and the engine

have cooled down.

REMOVING THE MACHINE FROM
STORAGE

1. Check the tire air pressure and inflate the tires if they
are low.

2. Jack the machine up and remove the support blocks.

3. Install the battery. Before installing the battery, make
sure it is fully charged.

4. Check the fan belt tension.

5. Check all fluid levels (engine oil, transmission/
hydraulic oil, engine coolant and any attached
implements).

6. Check all coolant, hydraulic and fuel hoses for cracks,
hardening, bubbles and leaks.

7. Check all control levers and the brake for proper
function, repair or lubricate as necessary.

8. Start the engine. Observe all gauges. If all gauges are
functioning properly and reading normal, move the
machine outside.

9. Once outside, park the machine securely set the
parking brake, place the control levers in the neutral
lock position and let the engine idle for at least 5
minutes.

10.Shut the engine off and walk around machine and
make a visual inspection looking for evidence of oil or
water leaks.

11.With the engine fully warmed up, release the parking
brake and test the brakes for proper adjustment as you
move forward. Adjust the brakes as necessary.

7. Keep the machine in a dry place where the machine is
sheltered from rain. Cover the machine.
