SECTION 1: IMPORTANT SAFE OPERATION PRACTICES
WARNING: This symbol points out important safety instructions which, if not followed, could endanger
the personal safety and/or property of yourself and others. Read and follow all instructions in this
manual before attempting to operate or service this vehicle. When you see this symbol - heed its
warning.
WARNING:
Engine exhaust, some of its constituents, and certain vehicle components contain
or emit chemicals known to the State of California to cause cancer and birth defects or other
reproductive harm
DANGER: This vehicle is designed to be operated according to the rules for safe operation in
this manual. As with any type of vehicle, carelessness or error on the part of the operator can
result in serious injury. Failure to observe the following safety instructions could result in
serious injury or death.
.
General Operation
1. Read, understand, and follow all instructions on the
vehicle and in the manual before attempting to
operate or service. Keep this manual in a safe
place for future and regular reference and for
ordering replacement parts.
2. This is an off-road utility vehicle and it should not be
operated on public highways. Know and comply
with all laws and regulations governing the use of
off-highway vehicles in your area.
3. This vehicle handles and maneuvers differently
than a normal passenger car. Sharp high speed
turns and abrupt maneuvers can cause vehicle to
roll over or go out of control. Slow down when
turning and avoid abrupt maneuvers.
4. Handling and maneuvering characteristics of
vehicle change depending upon cargo load. Heavy
loads affect steering, braking, stability, and overall
handling of vehicle.
5. Be familiar with all instructions and controls and
their proper operation before starting vehicle.
6. Never allow adults to operate this vehicle without
proper instruction.
7. Never allow children under 16 years old to operate
this vehicle. Children 16 years old and over should
read and understand the operation instructions and
safety rules in this manual and should be trained
and supervised by a parent.
8. Watch for traffic when operating near or crossing
roadways. This vehicle is not intended for use on
any public roadway.
9. Do not operate this vehicle while under the
influence of alcohol or drugs.
10. Never carry more than one passenger. This vehicle
is designed to carry the driver and one passenger
only. No riders are allowed in cargo box or
anywhere else on vehicle.
11. Keep all body parts (i.e. head, arms, hands, legs,
feet) inside vehicle when vehicle is in motion.
12. Always remain seated and keep both hands on the
steering wheel when driving the vehicle.
13. Sit on the center of the seat and keep both feet
within the foot platform perimeter. Clean foot
platform if dirty and remove any debris from around
foot controls, e.g. brake pedal.
14. Do not misuse the utility vehicle. It is an utility
vehicle, not a recreation vehicle or toy.
Recreational riding can lead to accidents, severe
bodily injury or death.
15. Inspect area around vehicle before moving, especially in reverse. Back up slowly. Always look down
and behind before and while backing to avoid a
back-over accident. Keep bystanders out of area.
16. Avoid driving through water, since loss of control
may occur. Drive belt may slip if exposed to water
thus reducing vehicle pulling power and stopping
vehicle entirely.
17. Always use vehicle lights while operating in low
light situations.
18. Do not mount or leave vehicle while it is in motion or
in actual operation.
19. Avoid sudden starts, stops, or turns and always use
a level turn-around area.
20. Never leave vehicle unattended with the key in the
ignition. Always turn key to the “Stop” position, set
the parking brake and remove key.
21. Check overhead clearances carefully before driving
under low hanging tree branches, wires, etc.,
where the operator may be struck or pulled from the
unit, which could result in serious injury.
22. Improper use of the vehicle or failure to properly
maintain it could result in decreased vehicle
performance or personal injury.
23. Engine must be stopped when cleaning, servicing,
adjusting, repairing, or installing attachments on
utility vehicle.
24. After striking foreign objects, stop the unit and shut
off the engine. Inspect for damage and repair the
damage before restarting and operating
equipment.
25. Do not start or operate vehicle in an inside area,
unless it is adequately ventilated. Engine exhaust
3
contains carbon monoxide fumes, which are very
poisonous and can be deadly.
26. Do not change engine governor setting or over
speed the engine. The governor is set at the factory
for safe operating speed.
27. Assure safety interlock switch is adjusted correctly
so engine cannot be started unless gearshift is in
the neutral position.
28. Do not touch engine or muffler while engine is
running or soon after it is stopped. They will be hot
and can cause a burn.
29. Always inspect your vehicle each time you use it to
make sure it is in safe operating condition. Always
follow the inspection and maintenance procedures
and schedules described in this manual.
30. If situations occur which are not covered in this
manual, use care and good judgement. Contact
your local service center or call toll free 1-877-2828684 for assistance and the name of your nearest
service center.
Slope Operation
Slopes are a major factor related to loss of control and
rollover accidents, which can result in severe injury or
death. If a slope is steeper than a 15° incline, do not
operate this unit on that area. Exercise extreme caution
while operating on slopes.
DO:
1. Travel straight up and down slopes, not across.
Exercise extreme caution when changing direction
on slopes.
2. Travel slowly while on a slope. Always keep the
forward speed limited when going down slopes to
take advantage of the motor braking action.
3. Keep all movement on the slopes slow and gradual.
Avoid starting or stopping on a slope.
4. Avoid slopes with slippery, loose, or bumpy
surfaces as they are especially hazardous.
5. Use extra care while carrying cargo. It may affect
the stability of the vehicle. Spread the load evenly
or tie down.
Do Not:
1. Do not travel near drop-offs, ditches or
embankments. The vehicle could suddenly turn
over if a wheel is over the edge of a cliff, ditch, or if
an edge caves in.
2. Do not stop or start suddenly when going uphill or
downhill. Be especially cautious when changing
direction on slopes.
3. Do not turn sideways to the hill. The vehicle may roll
over. If you must turn, go slow and do so carefully
and gradually.
4. Do not carry cargo on steep slopes or tow loads.
Children
1. Tragic accidents can occur if the operator is not
alert to the presence of children. Children are often
attracted to the vehicle. They do not understand the
dangers. Never assume that children will remain
where you last saw them. Avoid run over accidents.
a. Keep children out of the immediate area of
the vehicle and in watchful care of a
responsible adult other than the operator.
b. Be alert and turn the vehicle off if a child
enters the area.
c. Before and while backing, look behind and
down for small children.
d. Never carry children, they may fall off and be
seriously injured or interfere with safe vehicle
operation.
e. Use extreme care while approaching blind
corners, doorways, shrubs, trees or other
objects that may block your vision of a child
who may run into the path of the vehicle.
f. Remove key when vehicle is unattended to
prevent unauthorized operation.
2. Never allow children under 16 years old to operate
this vehicle. Children 16 years old and over should
read and understand the operation instructions and
safety rules in this manual and should be trained
and supervised by a parent.
3. Do not let children ride in the cargo box, in the
driver’s or passenger’s lap or anywhere other than
the passenger seat. Never give small children a
ride; not even in the passenger seat. They may fall
off.
Cargo Box Loading/Operation
1. Do not exceed vehicle’s Total Load Capacity rating
of 1,400 lb. This includes operator, passenger,
accessories, and cargo.
2. Do not exceed 1,000 lb. load in cargo box.
3. Spread load evenly and secure to prevent
movement.
4. Do not load above height of cargo box front panel.
Load could shift forward and injure driver or
passenger.
5. Avoid loads which exceed the physical dimensions
of cargo box.
6. Go slow. Heavy loads will affect steering, braking,
stability, and overall handling of the vehicle. Limit
loads to those that can be safely controlled.
7. Avoid sudden starts, stops, and turns which could
cause load to shift.
Cargo Box Lift
1. Stop vehicle on level ground and set Parking Brake
before raising cargo box.
2. On manual lift units, unload cargo box before
raising cargo box by hand.
3. When manually raising cargo box, make sure
Manual Support Lift Rod is securely locked before
leaning under raised cargo box.
4
4. Do not operate vehicle with cargo box in raised
position.
5. Do not operate vehicle with cargo box latch
unlatched. Always re-latch upon manually lowering
cargo box.
6. When using optional electric lift:
• Stay in driver’s seat.
• Keep body parts away from cargo box and keep all
bystanders away.
• Do not allow rear wheels to hang over the edge of a
drop-off when raising cargo box. Cargo box weight
may shift over center and cause vehicle to tip over
backwards.
Towing
• Always use an approved hitch and hitch point
provided on the utility vehicle.
• Do not tow more than 1200 lb. (545 kg) rolling
weight (i.e. trailer plus cargo).
• Never load more than 100 lb. (45.5 kg) tongue
weight on tow bracket provided.
• Go slow and use extra care when towing a trailer.
Allow for increased braking distance. Load trailer
properly.
• Do not tow heavy loads on slopes greater than 5°
incline. When going downhill or turning, the extra
weight tends to push the tow vehicle and may
cause you to loose control (i.e. braking and steering
ability are reduced, towed equipment may jackknife and cause utility vehicle to overturn).
Service
Safe Handling Of Gasoline:
1. To avoid personal injury or property damage use
extreme care in handling gasoline. Gasoline is
extremely flammable and the vapors are explosive.
Serious personal injury can occur when gasoline is
spilled on yourself or your clothes which can ignite.
Wash your skin and change clothes immediately.
a. Use only an approved gasoline container.
b. 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.
c. When practical, remove gas-powered
equipment from the truck or trailer and refuel
it on the ground. If this is not possible, then
refuel such equipment on a trailer with a
portable container, rather than from a
gasoline dispenser nozzle.
d. 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.
e. Extinguish all cigarettes, cigars, pipes and
other sources of ignition.
f. Never fuel machine indoors.
g. Never remove gas cap or add fuel while the
engine is hot or running. Allow engine to cool
at least two minutes before refueling.
h. Never over fill fuel tank. Fill tank to no more
than ½ inch below bottom of filler neck to
allow space for fuel expansion.
i. Replace gasoline cap and tighten securely.
j. If gasoline is spilled, wipe it off the engine
and equipment. Move unit to another area.
Wait 5 minutes before starting the engine.
k. To reduce fire hazards, keep machine free of
grass, leaves, or other debris build-up. Clean
up oil or fuel spillage and remove any fuel
soaked debris.
l. Never store the machine or fuel container
inside where there is an open flame, spark or
pilot light as on a water heater, space heater,
furnace, clothes dryer or other gas
appliances.
WARNING: Your Responsibility: Restrict the
use of this vehicle to persons who read,
understand and follow the warnings and
instructions in this manual and on the unit.
