A MESSAGE FROM THE PEOPLE WHO BUILT YOUR CENTAUR
Thank you for selecting a CENTAUR amphibious, off-road utility vehicle!
Ontario Drive & Gear Limited has been building off road vehicles since 1967. By listening carefully to our
customers and responding to their needs, we have been constantly improving them and will continue to do
so.
Over twenty-five thousand vehicles have provided reliable service all over the world. From Britain to the
Far East, Alaska to the Antarctic, and from the tropical forests of South America to the deserts of Saudi
Arabia. We are proud to provide you with a vehicle that represents the ultimate in amphibious, all-terrain
transportation.
Your safety and the safety of all CENTAUR users is of the greatest concern to us. You will find numerous
safety statements in this manual. Please read and follow them carefully. Always be safety conscious when
you operate your CENTAUR and remember it is a motorized vehicle.
The CENTAUR is easy to drive and you will soon be tempted to take on new challenges. Please take the
time to develop your driving skills before doing so. Observe the recommendations outlined in this Opera-
tor’s Manual and remember; some things are just impossible, even with a CENTAUR.
WELCOME TO THE WORLD WIDE CENTAUR FAMILY!
Centaur Service Manual

PREFACE
This manual describes the controls, operation and basic maintenance procedures for all CENTAUR vehicles from when first
produced. Please take the time to read this manual carefully, for your safety and that of others. By following these instruc-
tions, you will ensure extended, trouble free operation of your vehicle.
For maintenance and adjustment of the engine, refer to the engine manufacturer’s operation and maintenance manual in-
cluded in your vehicle’s information package.
Before you drive your CENTAUR, make sure you understand how to use all controls, particularly the brakes and steering
system. Learn how to drive your vehicle in an open level area, away from buildings, trees and other obstacles, until you are
completely familiar with its operating characteristics. Drive very slowly until your driving skills improve, and drive with
caution and consideration at all times. The risk of accident or injury is greatest during the first weeks of use. Take special care
during this period. ALWAYS RESPECT OUR ENVIRONMENT.
CAUTION TO THE CENTAUR OWNER/OPERATOR
• Make sure everyone who drives this vehicle receives proper operating instructions and reads this Operator’s Manual.
• No one under the age of 16 should be allowed to operate the CENTAUR. Children under the age of 16 may not have the
skills, abilities or judgement needed to operate the Centaur safely and may be involved in an accident causing severe
injury or death.
• Never allow anyone under the influence of alcohol or any other intoxicating substance to drive or ride in the vehicle.
• Wear an approved safety helmet and eye protection when driving or riding in the vehicle.
• Special operating and safety procedures described in this manual must be observed before and during water operation as
outlined in Section 5.6.
• The use of approved hearing protection is recommended.
• Equip your vehicle with a fire extinguisher and a first aid kit.
• Equip your vehicle with basic tools for emergency repairs.
• Before starting your engine, check for spilled fuel and wipe any up immediately. Any fuel is a potentially explosive
substance that can cause serious personal injury when ignited.
• Keep the floor pans secured in place at all times. Fingers, feet, animal tails or paws can be injured in the drive components
beneath the floor pans. The floor pans also help keep damaging debris out of the drive components.
• Make sure all passengers remain seated while the vehicle is in motion. Advise your passengers to hold onto the vehicle at
all times.
• Never overload your vehicle. Trying to steer an overloaded vehicle can damage the steering system. Overloading your
vehicle can lead to costly damage to steering system, transmission, drive chains, axles or bearings. Follow the recom-
mended load capacity for your vehicle listed in Section 1.
• Do not drive the vehicle at high speeds over unfamiliar or rough terrain. Personal injury or vehicle damage may result.
• Certain terrain and steep hills cannot be traversed safely with the Centaur or any other vehicle. Do not attempt to drive
over terrain that is questionable.
• Use common sense at all times when driving your vehicle.
IMPORTANT
Operate this vehicle with safety constantly in mind. Off-road vehicles face unpredictable and often hazardous terrain condi-
tions. It is ultimately the operator’s responsibility to handle the vehicle safely within its limitations and to decide when and
where to travel.

SECTION 1
GENERAL INFORMATION
1.1 AMPHIBIOUS OPERATION
The CENTAUR is amphibious and capable of traversing calm
water. Special operating procedures and safety precautions
must be observed before entering the water and during am-
phibious operation. Do not drive your vehicle into water until
you have read Section 5.6 Amphibious Operation.
1.2 MAINTENANCE PROCEDURES
Maintenance procedures described in this manual can be car-
ried out by the operator. These procedures include:
1. checking fluid levels
2. changing the engine and transmission oil
3. cleaning and replacing filters
4. preventative maintenance
5. inspections, adjustments, repairs and trouble- shooting
If you perform your own maintenance, carefully follow the
lubrication and preventative maintenance schedule (Section
7.7). By following this schedule, you will receive trouble
free, long term service from your vehicle. A Centaur Service
Manual on CD-ROM is available from your Centaur dealer.
Your CENTAUR dealer will perform regular maintenance and
lubrication for a reasonable service charge.
The trouble-shooting chart (Section 8) contains information
for locating and correcting mechanical problems. In many
cases, potential problems can be identified by unusual noises,
sluggishness or vibration, before they result in a breakdown.
Refer to the chart to identify these symptoms. Take immedi-
ate corrective action or take the vehicle to a CENTAUR dealer
for service.
This manual does not provide detailed maintenance or serv-
icing information for the engine. Refer to the engine manu-
facturer’s manual (supplied with each CENTAUR) for im-
portant warranty, service and operating information.
If the engine requires servicing, take the vehicle to an author-
ized engine service outlet.
1.3 WIND CHILL FACTOR
Why does it feel much colder outdoors on a windy day than
when there’s no wind, especially in winter? The cooling ef-
fect of the wind makes it feel that it’s colder than it really is.
This combined effect of wind and low temperature is known
as the “wind chill factor”.
Centaur operators should be aware of the wind chill factor.
Dress warmly and make sure exposed skin is protected. Pay
particular attention that young passengers are properly “bun-
dled up” with their hands and faces well protected.

1.4 MODEL IDENTIFICATION
The vehicle identification plate is fastened to the upper frame
to the right of the passenger’s knee. The model and serial
numbers are stamped into it. Model identification starts with
“V”, followed by four numbers and a letter or two, either G
(for gas), D (for diesel) or DT (for diesel turbo), for example
V2000G. The month and year that the vehicle was manufac-
tured can be established from the serial number: the first two
digits indicate the year and the second two digits indicate the
month (ie. Serial No. 0001004 was manufactured in January
2000).

2.1 NEW VEHICLE “BREAK-IN” PROCEDURE
To obtain long term, trouble free service from your vehicle,
observe the following break-in guidelines:
1. Vary the speed of the vehicle for the first tank of fuel.
Avoid full power during break-in period.
2. Check engine and transmission oil levels daily during
break-in period.
3. Change the transmission oil after initial 25 hours of op-
eration. Failure to do so can result in damage to the trans-
mission bearings or gear surfaces. Refer to Section 6.2.2
for transmission oil changing instructions.
4. Change the engine oil after the first 25 hours of opera-
tion. Refer to Section 6.1.3 of this manual for oil change
information.
5. Never overload your vehicle. Trying to steer an over-
loaded vehicle can over pressurize and damage the steer-
ing system. This will lead to a loss of steering control.
Overloading the vehicle can lead to premature steering
system failure and costly damage to drive chains, axles
or bearings. Follow the recommended load capacity for
the vehicle listed in Section 1.4.
2.2 PRE-OPERATION CHECKS
Carefully follow the engine manufacturer’s recommended pre-
operation/daily checks as well as the following:
1. Check the fuel level on the gauge.
2. Check the air pressure in all tires. All tires should be the
same pressure. For light use with low payloads pressu-
rize to 3.5 psi (24 kPa). For heavy use with high loads
use up to 7 psi (48 kPa.)
3. Test the operation of the gas pedal by pressing to the
floor and releasing it. The throttle must operate smoothly
and return automatically to the fully closed position.
4. Test the operation of the steering lockout by lowering
the driver’s armrest. The steering wheel should turn freely
either way but be locked in the centre position when the
armrest is in the raised position.
5. Check the brake travel by pressing on the pedal. See
Section 7.3.4 for proper adjustment details.
6. Check the engine intake and exhaust screen for obstruc-

tions. Clear any debris that has accumulated.
2.3 CARRYING PASSENGERS AND CARGO
1. Keep cargo as low as possible and evenly distributed.
2. Use extreme CAUTION when negotiating inclines with
a loaded vehicle. Heavy loads and high loads decrease
the stability of the vehicle and may cause it to roll. Be
prepared to shift occupant weight and load forward or
have passengers get out of the vehicle to climb an in-
cline.
3. Secure cargo to prevent it from shifting while driving.
2.4 FUELING THE VEHICLE
Gasoline and diesel fuel are extremely flammable and
can explode under certain conditions. Do not add fuel
while the engine is running or hot. If fuel is spilled in,
on or around the vehicle, wipe it up immediately. Flush
out any fuel spilled in the vehicle with water and allow
it to drain out through the drain plug holes. Do not
smoke when filling the fuel tank.
The Centaur is equipped with a 42 litre (9.2 Imp. Gal., 11.1
U.S. Gal.) polyethelene fuel tank located underneath the driv-
er’s seat. Depending on loading and driving conditions, a
Centaur can be driven for 7 to 12 hours on one tank of fuel.
Verify your vehicle’s actual fuel consumption before attempt-
ing any long trips. Never travel in remote areas or set out on
long trips without a full tank of fuel and adequate spare fuel
stored in approved watertight fuel containers.
The fuel filler neck and fuel cap are located on the left side of
the vehicle behind the driver’s seat. Replace the fuel cap if
fuel leakage occurs, or if moisture is detected in the fuel. Use
ODG Part No. 126-46 fuel cap.
Never fill the tank to the point where the fuel level rises into
the filler neck. If the tank is overfilled, heat may cause the
fuel to expand and overflow through the vent.
Portable fuel containers may contain contaminants (dirt, wa-
ter, etc.) that will cause engine operating problems. Use only
clean, approved fuel containers.
After filling the fuel tank, be sure the fuel cap is replaced
securely. Do not drive the vehicle unless the fuel cap is prop-
erly in place.

SECTION 2
GENERAL OPERATING INFORMATION
Never use untreated gasoline that has been stored for more
than 45 days. Stale gasoline can cause gum deposits to form
in the fuel lines and carburetor. These deposits clog the fuel
system and cause engine starting and operating problems.
When storing the CENTAUR for 45 days or more, use ODG
Part No. 125-85 Fuel Stabilizer to treat fuel in the fuel tank
and fuel containers.
Centaur 950 - Gasoline
Use clean, fresh, unleaded gasoline with a minimum of 85
octane. Purchase fuel in quantity that can be used within 30
days to assure fuel freshness. We recommend the use of Briggs
& Stratton gasoline additive; ODG part no. 127-77. Leaded
gasoline may be used if it is commercially available and
unleaded is unavailable.
Note: Some fuels, called oxygenated or reformulated
gasolines, are gasolines blended with alcohols or ethers. Ex-
cessive amounts of these blends can damage the fuel system
or cause performance problems. Do not use gasoline which
contains Methanol. If any undesirable operating symptoms
occur, use gasoline with a lower percentage of alcohol or ether.
Keep fuel tank full. Do not over-fill fuel tank. Allow space
for fuel expansion. Check for fuel leaks at fuel filter,
carburetor, fuel pump, etc.
Centaur 950DT - Diesel Turbo
Use clean, fresh diesel fuel with a minimum of 40 cetane.
Purchase fuel in quantity that can be used within 30 days to
assure fuel freshness.
Do not use kerosene or gasoline instead of diesel fuel.
Failure to observe this caution will damage the engine.
Keep fuel tank full. Do not over-fill. Allow space in tank for
fuel expansion. Check for fuel leaks at fuel filter, injector
pump, fuel lines, etc.
If the fuel tank does run dry, use the priming pump on the fuel
filter to bleed the air from the fuel line to restart the engine
more easily.
2.5 VENTED FUEL SYSTEM
Centaur models have fuel tanks that are vented through a spe-
cial hose connected to the filler neck assembly that runs along
the firewall to a position up under the engine cover.

OPERATING INSTRUCTIONS
3.1 STEERING
The steering wheel is used to turn the vehicle whenever the
engine is running. When moving forward, steering is similar
to an automobile. When moving in reverse, steering is oppo-
site to an automobile, similar to backing up a trailer.
When moving in reverse, steering operation is opposite
to automobiles.
The steering system works whenever the engine is running,
even when the gear selector is in neutral. The CENTAUR is a
skid steer vehicle. During a turn, the rear of the vehicle swings
outward as the vehicle pivots on the tires on the inside of the
turn. To make a right hand turn, the rear of the vehicle skids
out to the left. To make a left hand turn, the rear of the vehi-
cle skids out to the right.
When turning, the back of the vehicle swings to the op-
posite direction of the turn. Always take care to avoid
hitting persons or objects with the rear of the vehicle!
Serious injury or death can result!
The steering system is powered by a hydrostatic transmission
and works best when engine r.p.m. is higher than at idle. Avoid
turning the steering wheel when engine is idling.
Do NOT use steering unless vehicle is moving. Do NOT
use steering to assist in entering the vehicle. Damage to
the steering system could result.
Centaur vehicles built after August 2001 have a steering lock-
out system. The armrest on the driver’s side is mechanically
linked to the steering control. The steering wheel is locked in
the center position when the armrest is in the raised position.
When the armrest is in the lowered position, the steering is
unlocked and ready for use.
Ensure armrest is lowered and steering wheel moves
freely before driving the Centaur. If the steering lockout
feature malfunctions, steering will be impaired which
could cause an accident resulting in serious injury or
death.
3.2 BRAKES
The Centaur has a foot operated brake pedal. To stop the
vehicle, press firmly on the brake pedal.
3.3 PARKING/EMERGENCY BRAKE
The Centaur is equipped with a parking/emergency brake.
The lever is located midpoint under the dash and is activated
by pulling towards the driver. Release the brake by pushing
the button on the end of the lever and pushing the lever as far
forward as possible.
3.4 THROTTLE CONTROL
Vehicle speed is controlled by the accelerator pedal. To in-
crease vehicle speed, press on the accelerator pedal. To de-
crease vehicle speed, remove pressure on the accelerator pedal.
3.5 STARTING PROCEDURE
Never start or run the engine in a closed building or
confined area. Engine exhaust gases contain poisonous
carbon monoxide. Carbon monoxide is odourless, col-
ourless and can cause serious personal injury or death.
All Centaur models are equipped with key operated, electric
start systems.
Centaur vehicles built after December 2001 have a neutral
safety switch that prevents the vehicle from being started
unless the vehicle gear selector is in neutral.
3.5.1 Gasoline Powered
1. Shift the transmission into neutral.
2. Use the choke if the engine is cold. Do not press down
on the accelerator pedal if using the choke.
3. Turn the key to the “START” position.

SECTION 3
OPERATING INSTRUCTIONS
Figure 3-1. Ignition Switch
Do not operate the starter continuously for more than 5
seconds or the starter may overheat. Wait 30 seconds
between each operation of starter to let it cool and the
battery power recover. Never attempt to restart the en-
gine until it completely stops. Always remove key from
switch when leaving vehicle unattended or when vehi-
cle is not in use.
4. Release the key as soon as the engine starts: the key will
automatically return to the “RUN” position.
5. Push the choke in halfway after the engine starts, and
push it in all the way as the engine warms up.
6. If the engine fails to start, refer to the trouble-shooting
chart in Section 8 for corrective action.
3.5.2 Diesel Powered
1. Shift the transmission into neutral.
2. Turn the key to the “ON” position. The “DIESEL
PREHEAT” light will come on for five seconds.
3. When the “DIESEL PREHEAT” light goes out, turn the
key to the “START” position.
4. Release the key as soon as the engine starts; the key will
automatically return to the “RUN” position.
5. If the engine fails to start, refer to the trouble-shooting
chart in Section 8 for corrective action.
3.6 STOPPING THE ENGINE
Bring the vehicle to a complete stop. Release the accelerator
pedal. Ensure that the steering wheel is positioned such that
the vehicle doesn’t turn. Let the engine speed return to idle
and turn ignition switch to the “OFF” position. Always re-
move key from ignition switch when leaving the vehicle un-
attended.
3.7 SELECTING AND CHANGING TRANSMISSION
GEARS
The CENTAUR is equipped with a four position transmis-
sion. The gearshift lever is located to the left of the dash.
* R (Reverse) - for backing up the vehicle
* Neutral - for starting the engine or idling
* L (Low) - for use when extra pulling power or very low
speed is required in rough terrain.
* H (High) - for general use at normal operating speeds.
Inside the transmission, there is a synchronizer system or
clutch brake on the input shaft to allow for easier and more
accurate shifts. When you apply force to the shift lever, it is
transmitted through push/pull cables to the transmission,
where it forces a gear to slide on the input shaft. The move-
ment of the gear on the shaft is restricted by springs and balls
within the input shaft so that extra force must be applied, al-
lowing the synchronizer to brake the rotating shaft to a stop.
This reduces gear grinding during shifting.
Figure 3-7. Direction of gearshift travel
and gear positions
If the gear does not easily engage, it is possible that the teeth
are clashing directly. If this is the case, pushing harder may
not help. The input shaft must be allowed to start turning again
and the shift attempt made over.
The shift box is designed to allow one lever to be used to shift
both high and low gears and reverse. There is a neutral posi-
tion in which the lever can be moved side to side. The mecha-
nism inside the transmission does not allow two gears to be
engaged at one time. Access to low, high, or reverse is only
possible from the neutral position. Shifting works best when

9
SECTION 3
OPERATING INSTRUCTIONS
the engine is running. To shift into high gear after the engine
is running:
1. Ensure that the lever is in neutral. Pause for a few sec-
onds, and then;
2. Push firmly and quickly into the high gear position.
This works best if the brakes are NOT applied. If this doesn’t
work, put the lever back into neutral, step on the gas pedal to
rev the engine briefly (1500 rpm), let the engine idle down,
and then try the shift again. Repeat until it slides into gear.
The technique to shift into low gear is identical to shifting
into high.
To shift into reverse, move the lever to the right and pull down
firmly. Less force is required to shift into reverse. Reverse
does not have a synchronizer so it is very important that the
engine is idling. If reverse gear does not engage the first time,
use the same technique as for shifting into high and low.
Do not attempt to move the gearshift from the neutral
starting position until the engine idles down completely.
The Centaur is equipped with an automatic clutch that
is activated by engine speed. If the engine idle speed is
too high, the transmission will grind during gear en-
gagement.
3.8 HEADLIGHTS
The CENTAUR is equipped with 4 headlights that are oper-
ated through the dash mounted light switch. To turn the lights
on, push the light switch forward and down. The first posi-
tion turns on two lights with a flood pattern. The second po-
sition turns on the other two driving lights in addition to the
two flood lights.
Do not leave the lights on for any length of time when
the engine is not running. Leaving them on will drain
the battery.

SECTION 4
DRIVING PROCEDURES
4.1 DRIVING STRAIGHT AHEAD
Ensure the driver’s armrest (if equipped) is in the lowered
position. Shift the transmission into LOW or HIGH. Press
down on the accelerator pedal slowly until the clutch system
engages and the vehicle moves forward.
4.2 STOPPING THE VEHICLE
Reduce pressure on the accelerator pedal. Press carefully on
the brake pedal.
Do not apply brakes abruptly. The brakes are very ef-
fective and sudden braking may cause you or your pas-
sengers to be thrown from the vehicle and could result
in serious injury or death. Never use excessive force on
the brake pedal to apply the brakes. This can cause
tremendous pressure in the master cylinder and brake
caliper, resulting in component failure.
When driving the vehicle, do not “ride” the brakes. Keep
your foot off the brake pedal unless you are stopping the ve-
hicle.
4.3 TURNING THE VEHICLE
The Centaur is a skid steer vehicle. The rear of the vehicle
swings outward during a turn. Always take precautions when
making turns to avoid hitting persons or objects.
The steering system is powered by a hydrostatic transmission
and works best when engine r.p.m. is higher than at idle. Avoid
turning the steering wheel when engine is idling.
Do not use steering unless vehicle is moving. Damage
to the steering system could result.
4.4 BACKING THE VEHICLE UP
With the engine at idle, shift the transmission into reverse.
Press on the accelerator pedal slowly until the clutch system
engages and the vehicle moves backward. Increase speed by
gradually increasing pressure on the accelerator pedal.
4.4.1 Turning The Vehicle While Backing Up
Carefully practice backing up and turning in an open area
until you become accustomed to this procedure. Take pre-
cautions to avoid hitting persons or objects.
When turning in reverse, steering operation is opposite
to automobiles, similar to backing up a trailer.
