SAFE 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.
BEFORE OPERATING THE
VEHICLE
Know your equipment and its limitations. Read this
entire manual before attempting to start and operate
the vehicle.
1. General
• Pay special attention to the safety labels on the
vehicle.
• 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.
(1) ROPS
(2) Seat belt
• Always use the seat belts. Check the seat belts
regularly and replace if frayed or damaged.
• Do not operate the vehicle or any implement
attached to it while under the influence of alcohol,
medication, controlled substances or while fatigued.
• 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.
• Never allow anyone without a valid driver's license
to operate this vehicle.
• Before allowing other people to use your vehicle,
explain how to operate and have them read this
manual before operation.
• 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, as appropriate or
required.
• This vehicle is for off road use only.
Kubota does not recommend operating on public
roads.
• In addition to the driver, only 1 passenger should
ride in the vehicle.
Minimum age for passenger is 5 years old.
• Keep all shields in place and stay away from all
moving parts.
• 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.
(See MAINTENANCE on page 48.)
• Keep your vehicle clean. Dirt, grease, and trash
build up may contribute to fires and lead to personal
injury.
• Use only implements meeting the specifications
listed in this manual or implements approved by
Kubota. (See VEHICLE LIMITATIONS on page
22.)
• The maximum cargo capacity of this vehicle is
200 kg (441 lbs.). Reduce cargo capacity to match
operating conditions.
Do not carry anything which significantly raises the
center-of-gravity and sticks outside the cargo bed.
• Do not modify the vehicle. Unauthorized
modification may affect the function of the vehicle,
which may result in personal injury.
SAFE OPERATION
RTV520

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/or loads carried too high. 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.
1. Starting to operate the vehicle
• Always sit in the operator's seat when starting
engine or operating levers or controls.
• Before starting the engine, make sure that the
range gear shift is in “NEUTRAL” position, that the
parking brake is engaged.
• 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.
• Be sure that the operator (and passenger) are
properly positioned and seat belts are appropriately
fastened.
• Do not operate or idle engine in a non-ventilated
area. Carbon monoxide gas is colorless, odorless,
and deadly.
2. Operating the vehicle
• Do not wear headphones while operating.
• 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.
(1) Trailer hitch (if equipped)
• Keep all shields and guards in place. Replace any
shields or guards that are missing or damaged.
• Avoid sudden starts. To avoid rollovers, slow down
when turning, on uneven ground, and before
stopping.
• The vehicle cannot turn with the differential locked
and attempting to do so could be dangerous.
• 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.
• Watch where you are going at all times. Watch for
and avoid obstacles. Be alert at row ends, near
trees, and other obstructions.
• When working in groups, always let the others
know what you are going to do before you do it.
• Never try to get on or off a moving vehicle.
• Do not stand between vehicle and trailer unless
parking brake is applied.
3. 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.
• Never assume that children will remain where you
last saw them.
• Keep children out of the work area and under the
watchful eye of another responsible adult.
• Be alert and shut your vehicle down if children enter
the work area.
• 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.
• Never allow children to operate the vehicle even
under adult supervision.
• Never allow children to play on the vehicle or on the
implement.
• Use extra caution when backing up. Look behind
and down to make sure area is clear before
moving.
4. Avoiding crystalline silica (quartz)
dust
To avoid serious injury or death from silica dust:
• Avoid exposure to dust containing crystalline silica
particles.
This dust can cause serious injury to the lungs
(silicosis).
Because crystalline silica is a basic component of
sand and granite, many activities at construction
sites produce dust containing crystalline silica.
Trenching, sawing and boring of material containing
crystalline silica can produce dust containing
crystalline silica.
SAFE OPERATION
6
RTV520

• If dust which contains crystalline silica is present,
there are guidelines which should be followed:
– Be aware of the potential health effects of
crystalline silica and that smoking may add to
the damage.
– Be aware of and follow OSHA (or other local,
State or Federal) guidelines for exposure to
airborne crystalline silica.
– Know the work operations where exposure to
crystalline silica may occur.
– Participate in air monitoring or training
programs offered by the employer.
– Be aware of and use optional equipment
controls such as water sprays, local exhaust
ventilation, and enclosed CABs with positive
pressure air conditioning, if the machine has
such equipment. Otherwise respirators shall be
worn.
– Where respirators are required, wear a
respirator approved for protection against
crystalline silica containing dust. Do not alter
the respirator in any way. Workers who
use tight-fitting respirators cannot have beards/
mustaches which interfere with the respirator
seal to the face.
– If possible, change into disposable or washable
work clothes at the work site; shower and
change into clean clothing before leaving the
work site.
– Do not eat, drink, use tobacco products, or
apply cosmetics in areas where there is dust
containing crystalline silica.
– Store food, drink and personal belongings away
from the work area.
– Wash hands and face before eating, drinking,
smoking, or applying cosmetics after leaving
the exposure area.
5. Operating on slopes
Slopes are a major factor related to loss-of-control and
roll-over accidents, which can result in severe injury or
death. All slopes require extra caution.
• Travel straight up or down hill.
• Reduce load when operating on hilly or over rough
terrain.
• Keep front wheels straight at crest of hill or going
over bumps.
• Do not stop or start suddenly when going uphill
or downhill. Be especially cautious when changing
direction on slopes.
• 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.
• When riding on soft terrain, turn front wheels
slightly uphill to keep vehicle on a straight line
across the hill.
• If the vehicle begins to tip, turn front wheels
downhill to gain control before proceeding.
– 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.
– 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.
– 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.
– Special attention should be made to the weight
and location of implements and loads as such
will affect the stability of the vehicle.
6. Operation in inclement conditions
• Only operate during daylight or with good artificial
light.
• Operate vehicle in an open, unobstructed area.
• Use helmet and/or protective gear for certain
operating conditions.
• Reduce speed according to trail, terrain and
visibility conditions.
• Never drive exceeding the limit of visibility. Slow
down near crest of hill until getting a clear view of
the other side.
• Stay alert for holes, rocks and other hidden hazards
in the terrain.
• Never cross any body of water where depth may be
unknown to the operator (Deep water is considered
anything in excess 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.
SAFE OPERATION
RTV520

7. Driving the vehicle at high speeds
• Be aware of the difference of 2WD and 4WD.
Check always the front wheel engagement carefully
before use, since the braking characteristics are
different between 2 and 4 wheel drive.
• Always slow the vehicle down before turning.
Turning at high speed may tip the vehicle over.
• Turn the headlights on.
• Drive at speeds that allow you to maintain control at
all times.
• Do not apply the differential lock while traveling at
high speeds. Locking the differential affects vehicle
control and may cause loss of control.
• 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.
8. Other miscellaneous
• Clean platform if dirty and remove any debris from
around foot controls.
• Always keep both hands on the steering wheel.
• Always keep arms and legs inside the operating
compartment.
• Never operate the vehicle while standing.
• Do not tow a cart with any riders on it.
• Never attempt wheelies, jumps or other stunts.
HAULING LOADS IN THE
CARGO BED
• No riders in cargo bed.
• Reduce cargo capacity when operating on rough or
hilly terrain.
• Do not overload the vehicle. Balance the loads
by evenly distributed and secure them properly.
Braking could shift the load and affect the vehicle
stability.
• Never operate vehicle with the cargo bed raised.
• Operate the cargo bed dump with vehicle stationary
and parking brake locked. Do not dump while
moving (if equipped).
• Operate the cargo bed dump on level ground only.
• Do not place hands or body under the cargo bed
when lowering bed.
• Braking distance increases when cargo bed is
loaded.
PARKING THE VEHICLE
• Lower all implements to the ground, place the
range gear shift in “NEUTRAL” position, set the
parking brake, stop the engine, and remove the
key.
• Make sure that the vehicle has come to a complete
stop before dismounting.
• Avoid parking on steep slopes, if possible, park
the vehicle on a firm and flat level of surface. If
not, park across the slope, set the parking brake(s)
and always lower the attachment (if equipped) to
the ground. Stop the engine, remove the key, and
chock the wheels.
Failure to comply with the instruction in this section
may allow the vehicle to move and could cause
injury or death.
(1) Parking brake lever
TRANSPORTING THE VEHICLE
• Disengage power to attachment(s) when
transporting or not in use.
• Do not tow this vehicle. Use a suitable truck or
trailer when transporting on public roads.
• Use extra care when loading or unloading the
vehicle into a trailer or truck.
• Make sure to secure the vehicle properly when
transporting.
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,
wear the appropriate safety gears.
• Allow the vehicle time to cool off before working on
or near the engine, muffler, radiator, and other hot
areas.
• Always stop the engine before refueling. Avoid
spills and overfilling.
• If fuel is spilled, do not attempt to start the engine
until the spill is cleaned up and vapors have
cleared.
• Refuel outdoors, do not refuel in an enclosed trailer
or building.

• 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.
• Before “Jump starting” a dead battery, read and
follow all of the instructions. (See JUMP STARTING
on page 29.)
• Keep first aid kit and fire extinguisher handy at all
times.
• Disconnect the battery's ground cable before
working on or near electric components.
• 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.
• To avoid sparks from an accidental short circuit,
always disconnect the battery's ground cable (-)
first and reconnect it last.

• Do not remove 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 removing the cap completely. If the vehicle
has a coolant recovery tank, add coolant or water
to the tank, not the radiator. (See Checking coolant
level on page 57.)
• Do not attempt to mount a tire on a rim. This should
be done by a qualified person with the proper
equipment.
• Always maintain the correct tire pressure. Do not
inflate tires above the recommended pressure
shown in the operator's manual.
• Securely support the vehicle when changing
wheels.
• Make sure that wheel bolts have been tightened to
the specified torque.
• Do not work under any hydraulically supported
devices. They can settle, suddenly leak down,
or be accidentally lowered. If it is necessary to
work under the vehicle or any vehicle elements for
servicing or adjustment, securely support them with
stands or suitable blocking beforehand.
• Escaping hydraulic fluid under pressure has
sufficient force to penetrate skin causing serious
personal injury. Before disconnecting hydraulic
lines, be sure to release all residual pressure.
Before applying pressure to the hydraulic system,
make sure that all connections are tight and that all
lines, pipes, and hoses are free of damage.
“High pressure fluid - Injection into body” hazard
warning.
• Fluid escaping from pinholes may be invisible. Do
not use hands to search for suspected leaks; use a
piece of cardboard or wood. Use of safety goggles
or other eye protection is also highly recommended.
If injured by escaping fluid, see a medical doctor
at once. This fluid will produce gangrene or severe
allergic reaction.
