I. Introduction
Chironex welcomes you to its growing family of new Spartan series Utility Vehicle owners. The Spartan has been designed for the Canadian
outdoors with careful attention paid to every detail. Proper set-up, maintenance and safe operating practices will help you get years of satisfactory
use from this vehicle.
Safety First
Chironex is fully aware of the need for safe operating procedures around all of our equipment. We hope you will make a sincere effort to put
safety above all other priorities. The Spartan Utility Vehicle was designed and built for work, recreation, and enjoyment; however, improper and
irresponsible operation could result in serious injury or death. Since this is an off-road vehicle, operators will seldom see the road safety and
warning signs they are accustomed to seeing on highways and public streets. This places additional responsibility on the driver to operate this
vehicle well within the safe operational limits and capabilities of the unit.
This manual has been prepared to instruct you in the safe and responsible operation of your Spartan Utility Vehicle. Read and abide by all safety
alert information about this vehicle. If you do not understand any part of this manual, contact your local dealer for additional information and
clarification. As the operator of this piece of equipment, you are in complete control. Only you can prevent an accident from happening.
Using This Manual
* Prior to any vehicle operation it is absolutely essential that you read and comprehend each section in this manual to develop an understanding of
your vehicle and for your safety. After reviewing this manual, store it in a dry and easily accessible place for future reference.
* The Operator’s Section is designed to help familiarize you with safety, assembly, operation, adjustments, troubleshooting, and maintenance.
Read this manual and follow the recommendations to help ensure safe and efficient operation.
* The information contained within this manual was current at the time of printing. Some parts may change slightly to assure you of the best
performance.
* To order a new Operator’s or Parts Manual contact your authorized dealer.

Getting Acquainted with your Utility Vehicle
This off-road utility vehicle is a very unique vehicle designed exclusively for off-road use. It is not designed, properly equipped, or licensed to be
safely operated on public streets and highways. This vehicle is designed to carry two people and a limited amount of gear or cargo comfortably
and safely over rough terrain.
Unlike ATVs that have handlebar steering, the Spartan Utility Vehicles have a steering wheel with easy handling rack-and pinion steering. The
steering’s tight turning radius makes this vehicle more maneuverable than most ATV’s. Its four wheeled independent suspension, large diameter
hi-flotation tires and high center-frame ground clearance adds up to excellent stability and a smooth ride over rough terrain. Outstanding traction
is achieved by using premium off-road ATV type tires in tandem with the engine mounted directly in front of the rear differential.
Also unlike an ATV’s one person “straddle saddle” seat, the Spartan UTV sports dual headrest cushioned seats with seat belts mounted in a
highly styled and protective full length body. Two passengers can ride comfortably in this vehicle protected from splashing water and mud. The
Brush Guard Bar mounted to the vehicle’s frame provides protection against low hanging limbs and briars.
The Brush Guard Bar also provides a mounting system for optional windshields, canopy tops and weather enclosures. It also serves as a mounting
base for many other optional cargo racks, gun and bow racks.
The dump box is for transporting materials and accessories such as camping equipment, tree stands, hunting gear, and fishing gear. A standard
hitch mounting plate enables quick installation of a rear hitch for pulling small trailers full of supplies, tools, gear, and game.
The Spartan UTV has some similarities to an ATV. Like an ATV it has a short wheelbase, narrow stance, and high center clearance all which
provide for narrow and difficult trail access. This combination of short wheelbase and narrow stance also enables this vehicle to be loaded in the
back of most full to mid-sized pickups for transport.
The Spartan UTV’s ground compaction and is very gentle on the ground and surrounding vegetation. The highly energized four wheeled
independent suspension system provides an incredibly soft ride and outstanding stability over difficult terrain.

Owner Assistance
The safety information should be viewed by the owner and the Warranty Registration card should be filled out by the dealer at the time of
purchase. The owner, upon purchasing the vehicle, should have participated in a short drivers training course with the dealer. This information is
necessary to provide you with quality customer service.
The parts on your Spartan Utility Vehicle have been specially designed and should only be replaced with genuine Chironex parts.
If customer service or repair parts are required contact a Chironex dealer. They have trained personnel, genuine repair parts and equipment
specially designed to repair Chironex products.
Record your Chironex Spartan Utility Vehicle serial number here for quick reference:
Model Number:___________________________

VI、Breaking-in period
The operating quality and longevity of the UTV depends on
taking proper care during the breaking-in period. During the
initial 1600 km of driving the various components of the UTV
should be allowed to wear into each other. Adhere to the
speed limit, keep total UTV payload to a minimum and carry
out periodic maintenance as per the guidelines in this manual.
(13) Choke
When operating the UTV in cold weather, if you
experience difficulty in starting the engine, pull out the choke.
After the UTV starts push down the choke to restore the
carburetor to normal operation.
1. Maximum permissible speed:
Mileage
Maximum permissible speed
< 800Km

800 - 1600Km
50Km/h
> 1600Km
60Km/h
Avoid full throttle starts, sudden acceleration or
deceleration during the breaking-in period.
2. Warming up engine
During the breaking-in period, it is necessary idle the
engine for 3-5 minutes after starting and warm it up.
This gives time for the engine oil and lubricants to
flow over surfaces in contact.
3. Coolant Temperature Monitoring
© Copyright Chironex Motorsports Inc. All Rights reserved.
- 20 -
During the breaking -in period, it is necessary to
monitor engine coolant temperature to avoid running
engine at low temperatures for long periods or at high
temperatures without coolant. This will accelerate
abrasion and cause damage to the engine cylinder.
4. Check if all nuts and bolts are properly tightened,
including those of transmission components.
5. First maintenance of vehicle
After the first 1000km, it is necessary to carry out a
complete maintenance. For maintenance instructions
refer to the “Maintenance and repair” section in this
manual.
VII、Maintenance and repair
WARNING：It is important to carry out a complete
maintenance after driving the UTV for 1000 km. The
operating quality and longevity of the UTV depends on
taking proper care during the breaking-in period.
