SAFE OPERATION
-1SAFE OPERATION
Careful operation is your best insurance against an
accident.
Read and understand this Operator's Manual carefully
before operating the vehicle.
All operators, no matter how much experience they may
have, should read this and other related manuals before
operating the vehicle or any implement attached to it. It is
the owner's obligation to instruct all operators in safe
operation.
1. BEFORE OPERATING THE VEHICLE
1. Know your equipment and its limitations. Read this
entire manual before attempting to start and operate
the vehicle.
2. Pay special attention to the Danger, Warning and
Caution labels on the vehicle.
3. Do not remove Roll-Over Protective Structures
(ROPS) for any application and fasten seat belts at all
times. This combination will reduce the risk of serious
injury or death, should the vehicle be upset.
If the ROPS is loosened or removed for any reason,
make sure that all parts are reinstalled correctly before
operating the vehicle.
Never modify or repair a ROPS because welding,
bending, drilling, grinding, or cutting may weaken the
structure.
A damaged ROPS structure must be replaced, not
repaired or revised.
If any structural member of the ROPS is damaged,
replace the entire structure at your local KUBOTA
Dealer.
5. Do not operate the vehicle or any implement attached
to it while under the influence of alcohol, medication,
controlled substances or while fatigued.
6. Carefully check the vicinity before operating the
vehicle or any implement attached to it. Check for
overhead clearance which may interfere with the CAB
or ROPS. Do not allow any bystanders around or near
the vehicle during operation.
7. Never allow anyone without a valid driver's license to
operate this vehicle.
8. Before allowing other people to use your vehicle,
explain how to operate and have them read this
manual before operation.
9. Never wear loose, torn, or bulky clothing around the
vehicle. It may catch on moving parts or controls,
leading to the risk of an accident. Use additional safety
items, e.g. helmet, safety boots or shoes, eye and
hearing protection, gloves, etc., as appropriate or
required.
10.This vehicle is for off road use only.
KUBOTA does not recommend operating on public
roads.
11.In addition to the driver, only 1 passenger should ride
in the vehicle.
Minimum age for passenger is 5 years old.
12.Keep all shields in place and stay away from all
moving parts.
13.Check brakes, speed control pedal, and other
mechanical parts for improper adjustment and wear.
Replace worn or damaged parts promptly. Check the
tightness of all nuts and bolts regularly. (For further
details, see "MAINTENANCE" section.)
14.Keep your vehicle clean. Dirt, grease, and trash build
up may contribute to fires and lead to personal injury.
15.Use only implements meeting the specifications listed
under "VEHICLE LIMITATIONS" in this manual or
implements approved by KUBOTA.
16.The maximum cargo capacity of this vehicle is 200kg.
Reduce cargo capacity to match operating conditions.
Do not carry anything which raises the center-ofgravity and sticks outside the cargo bed.
17.Do not modify the vehicle. Unauthorized modification
may affect the function of the vehicle, which may result
in personal injury.
(1) ROPS
(2) Seat belt
4. Always use the seat belts. Check the seat belts
regularly and replace if frayed or damaged.
SAFE OPERATION-2
2. OPERATING THE VEHICLE
Operator safety is a priority. Safe operation, specifically
with respect to overturning hazards, entails understanding
the equipment and environmental conditions at the time of
use. Some prohibited uses which can affect overturning
hazards include traveling and turning with implements
and loads carried too high etc. This manual sets forth
some of the obvious risks, but the list is not, and cannot
be, exhaustive. It is the operator's responsibility to be alert
for any equipment or environmental condition that could
compromise safe operation.
5. The vehicle cannot turn with the differential locked and
attempting to do so could be dangerous.
6. Do not operate near ditches, holes, embankments, or
other ground surface features which may collapse
under the vehicle's weight. The risk of vehicle upset is
even higher when the ground is loose or wet.
7. Watch where you are going at all times. Watch for and
avoid obstacles. Be alert at row ends, near trees, and
other obstructions.
8. When working in groups, always let the others know
what you are going to do before you do it.
9. Never try to get on or off a moving vehicle.
10.Do not stand between vehicle and trailer unless
parking brake is applied.
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 all levers
are in their neutral positions, that the parking brake is
engaged.
3. Do not start engine by shorting across starter
terminals or bypassing the safety start switch. The
vehicle may start in gear and move if normal starting
circuitry is bypassed.
4. Be sure that the operator (and passenger) seat belts
are fastened.
5. Do not operate or idle engine in a non-ventilated area.
Carbon monoxide gas is colorless, odorless, and
deadly.
C Operating
1. Do not wear headphones while operating.
2. Pull only from the trailer hitch (if equipped). Never hitch
to axle housing or any other point except trailer hitch;
such arrangements will increase the risk of serious
personal injury or death due to a vehicle upset.
C Safety for children
Tragedy can occur if the operator is not alert to the
presence of children. Children generally are attracted to
vehicles and the work they do.
1. Never assume that children will remain where you last
saw them.
2. Keep children out of the work area and under the
watchful eye of another responsible adult.
3. Be alert and shut your vehicle down if children enter
the work area.
4. Never carry children in the cargo bed. There is no safe
place for them to ride. No person under the age of 5
may ride as a passenger in this vehicle. A passenger
under 5 years of age requires special restraints which
are not available with this vehicle.
5. Never allow children to operate the vehicle even under
adult supervision.
6. Never allow children to play on the vehicle or on the
implement.
7. Use extra caution when backing up. Look behind and
down to make sure area is clear before moving.
8. Whenever possible, park your vehicle on a firm, flat
and level surface. If this is not possible, park it across
the slope. Set the parking brake(s), lower the
implements to the ground, remove the key from the
ignition and chock the wheels.
(1) Trailer hitch (if equipped)
3. Keep all shields and guards in place. Replace any that
are missing or damaged.
4. Avoid sudden starts. To avoid upsets, slow down
when turning, on uneven ground, and before stopping.
C Operating on slopes
Slopes are a major factor related to loss-of-control and tipover accidents, which can result in severe injury or death.
All slopes require extra caution.
1. Travel straight up or down hill.
2. Reduce load when operating on hilly or over rough
terrain.
3. Keep front wheels straight at crest of hill or going over
bumps.
4. Do not stop or start suddenly when going uphill or
downhill. Be especially cautious when changing
direction on slopes.
-3SAFE OPERATION
5. If vehicle stops or loses power going up a hill, lock
parking brake to hold vehicle on slope. Maintain
direction of travel and release brake slowly. Back
straight downhill while maintaining control. Do not turn
vehicle sideways. Vehicle is more stable in a straight
forward or rearward position.
6. When riding on soft terrain, turn front wheels slightly
uphill to keep vehicle on a straight line across the hill.
7. If the vehicle begins to tip, turn front wheels downhill to
gain control before proceeding.
(1) To avoid upsets, always back up steep slopes. If
you cannot back up the slope or if you feel uneasy
on it, do not operate on it. Stay off slopes too
steep for safe operation.
(2) Driving forward out of a ditch, mired condition or
up a steep slope increases the risk of a vehicle to
be upset backward. Always back out of these
situations. Extra caution is required with 4-wheel
drive mode because the increased traction can
give the operator false confidence in the vehicle's
ability to climb slopes.
(3) Keep all movement on slopes slow and gradual.
Do not make sudden changes in speed, direction
or apply brake and make sudden motions of the
steering wheel.
(4) Special attention should be made to the weight
and location of implements and loads as such will
affect the stability of the vehicle.
C Operation in inclement conditions
1. Only operate during daylight or with good artificial
light.
2. Operate vehicle in an open, unobstructed area.
3. Use helmet and/or protective gear for certain
operating conditions.
4. Reduce speed according to trail, terrain and visibility
conditions.
5. Never drive exceeding the limit of visibility. Slow down
near crest of hill until getting a clear view of the other
side.
6. Stay alert for holes, rocks and other hidden hazards in
the terrain.
7. Never cross any body of water where depth may be
unknown to the operator (Deep water is considered
anything above the bottom edge of the axle cap).
Choose a course within the waterway where both
banks have a gradual incline. Cross at a point known
to be safe.
5. Do not apply the differential lock while traveling at high
speeds. The vehicle may run out of control.
6. Avoid sudden motions of the steering wheel as they
can lead to a dangerous loss of stability. The risk is
especially great when the vehicle is traveling at high
speeds.
C Other miscellaneous
1. Clean platform if dirty and remove any debris from
around foot controls.
2. Always keep both hands on the steering wheel.
3. Always keep arms and legs inside the operating
compartment.
4. Never operate the vehicle while standing.
5. Do not tow a cart with any riders on it.
6. Never attempt wheelies, jumps or other stunts.
3. HAULING LOADS IN THE CARGO BED
1. No riders in cargo bed or anywhere else.
2. Do not overload vehicle. Securely anchor all loads.
3. Be sure load is evenly distributed.
4. Reduce cargo capacity when operating on rough or
hilly terrain.
5. Balance loads evenly and secure them. Braking could
shift the load and affect vehicle stability.
6. Never operate vehicle with the cargo bed raised.
7. Operate cargo bed dump with vehicle stationary and
parking brake locked. Do not dump while moving.
8. Operate the cargo bed dump on level ground only.
9. Do not place hands or body under the cargo bed when
lowering bed.
4. PARKING THE VEHICLE
1. Lower all implements to the ground, place all control
levers in their neutral positions, set the parking brake,
stop the engine, and remove the key.
2. Make sure that the vehicle has come to a complete
stop before dismounting.
3. Avoid parking on steep slopes, if at all possible park on
a firm and level surface; if not, park across a slope with
chock the wheels and always with attachment on the
ground.
Failure to comply with this warning may allow the
vehicle to move and could cause injury or death.
C Driving the vehicle at high speeds
1. Check the front wheel engagement. The braking
characteristics are different between 2 and 4 wheel
drive. Be aware of the difference and use carefully.
2. Always slow the vehicle down before turning. Turning
at high speed may tip the vehicle over.
3. Turn the headlights on.
4. Drive at speeds that allow you to maintain control at all
times.
SAFE OPERATION-4
(1) Parking brake lever
8. To avoid sparks from an accidental short circuit,
always disconnect the battery's ground cable (-) first
and reconnect it last.
5. TRANSPORTING
1. Disengage power to attachment(s) when transporting
or not in use.
2. Do not tow this vehicle. Use a suitable truck or trailer
when transporting on public roads.
3. Use extra care when loading or unloading the vehicle
into a trailer or truck.
6. SERVICING THE VEHICLE
Before servicing the vehicle, park it on a firm, flat and level
surface, set the parking brake, lower all implements to the
ground, place the range gear shift lever in neutral, stop the
engine and remove the key.
1. Allow the vehicle time to cool off before working on or
near the engine, muffler, radiator, etc.
2. Always stop the engine before refueling. Avoid spills
and overfilling.
3. Do not smoke when working around battery or when
refueling. Keep all sparks and flames away from
battery and fuel tank. The battery presents an
explosive hazard, because it gives off hydrogen and
oxygen especially when recharging.
4. Before "jump starting" a dead battery, read and follow
all of the instructions. (See "JUMP STARTING" in
"OPERATING THE ENGINE" section.)
5. Keep first aid kit and fire extinguisher handy at all
times.
6. Disconnect the battery's ground cable before working
on or near electric components.
7. To avoid the possibility of battery explosion, do not use
or charge the refillable type battery if the fluid level is
below the LOWER (lower limit level) mark. Check the
fluid level regularly and add distilled water as required
so that the fluid level is between the UPPER and
LOWER marks.
(1) Battery
9. Do not attempt to mount a tire on a rim. This should be
done by a qualified person with the proper equipment.
10.Always maintain the correct tire pressure. Do not
inflate tires above the recommended pressure shown
in the operator's manual.
11.Securely support the vehicle when changing wheels.
12.Make sure that wheel bolts have been tightened to the
specified torque.
13.Waste products such as used oil, fuel, hydraulic fluid,
and batteries, can harm the environment, people, pets
and wildlife. Please dispose properly.
See your local Recycling Center or KUBOTA Dealer to
learn how to recycle or get rid of waste products.
