VENGEANCE OWNER’S MANUAL

A Message from Mudd-Ox Inc.
Thank you for choosing the Mudd-Ox as your new amphibious ATV.
We began designing the first Mudd-Ox in 2005, spending years testing and developing the ultimate amphibious
vehicle. The first production machine rolled off the line in 2008 and was shipped to Australia. Since then, we have
expanded our model lineup to include the Mudd-Ox GT, XL, Fort Mac, and Vengeance to suit all your outdoor needs.
Our journey has continued to be full of adventure.
Safety is our number one concern. Be sure to read and understand this entire manual to ensure the safety of your-
self and others with the Mudd-Ox.
Mudd-Ox is proudly made in the USA. Our headquarters and manufacturing facility are located near the historic
town of Shipshewana, Indiana. We welcome everyone to come visit our facility and take in the local beauty that is
rural Indiana.

Identify Your Mudd-Ox
PIN Plate
Each Mudd-Ox has its own unique identification plate. It notates the Model and Product Identification Number
(PIN). This information is vital for identifying each individual Mudd-Ox and obtaining a state-issued title. Never
remove the PIN plate from the Mudd-Ox.
Locating the PIN
On the interior of the Mudd-Ox in front of the parking brake handle locates the PIN plate. It is visible without
removing any components, however removing the lower operator seat is recommended for best visibility.
Document Your Information
Write down the Model and PIN information just as it displays on the PIN plate to document your individual Mudd-Ox.

Warranty
Limited Warranty: Mudd-Ox Inc. (“Mudd-Ox”) hereby warrants to the original purchaser that any components of your
new Mudd-Ox vehicle manufactured by Mudd-Ox will be free from defects in material and workmanship for a period of
(1) year from date of purchase or 500 hours, whichever comes first, exempt as otherwise noted. Dealer demo vehicles are
warrantied for (30) days.
Mudd-Ox Warranty Responsibilities: Mudd-Ox, if notified of a defect in material or workmanship during the period of
warranty, will repair or replace, at its option, defective parts covered by this warranty at no charge other than the reason-
able cost for the transportation of components, if applicable. Mudd-Ox will also pay reasonable charges for necessary labor
to perform warranty repairs.
Warranty Claim Procedures: In order to be able to submit claims under this warranty, the original purchaser must main-
tain and operate the vehicle in accordance with instruction provided: in the Owner’s Manual; engine manufacturer’s manu-
al; in any manual related to components of the vehicle; and on labels affixed to the vehicle. To initiate a warranty claim pro-
cedure, the original purchaser must contact the Mudd-Ox Customer Service Department within (10) days of the discovery
of an alleged defect. Mudd-Ox’s Customer Service Department may be contacted using the following methods: by calling +1
260-768-7221, in person or by mail at Mudd-Ox Inc, 8525 W 750 N Shipshewana, IN 46565, or online at www.muddox.net.
The repair or replacement of any part(s) under this Limited Warranty shall not extend the term of the warranty beyond the
original term as set forth above. Products which Mudd-Ox Inc. determines violate such warranty shall be returned to the
BUYER at the BUYER’S expense. Any parts required for warranty that are not in the dealer’s inventory will be shipped to the
servicing dealer via UPS Ground or USPS priority mail at Mudd-Ox Inc. discretion.
General Exclusions: This limited warranty does not cover component failure or damage caused by any of the following:
abnormal strain or stress; neglect; abuse; theft; fire; improper assembly of components which were supplied in the factory
sealed carton after the vehicle left Mudd-Ox; improper maintenance or repair; modifications; damage caused by use of
non-Mudd-Ox accessories; or improper use of the vehicle including but not limited to: racing, jumping, stunt driving, or any
other uses prohibited in the Owner’s Manual. Additionally, this warranty does not cover vehicles which are leased, rented,
or used at a concession track. This warranty does not cover components not manufactured by Mudd-Ox. For warranty
information on components not manufactured by Mudd-Ox, please refer to each component’s respective manufacturer’s
warranty.
Specific Exclusions: This limited warranty does not apply to components which are subject to normal wear and tear. These
items are not limited to: axles; track keepers; wheels; tires; batteries; throttle; shift, steer and brake cables; drive belt; the
torque converter system; chain; seat; lights; fasteners; decals; or body panels and natural cosmetic discoloration of mate-
rial due to ultraviolet light. Shipping method of parts, incorrectly damaged components, downtime, and delivery charges
are not covered by this warranty. This warranty does not apply to the vehicle’s batteries. The batteries carry a separate
warranty provided by Mudd-Ox’s battery supplier. Please refer to the battery supplier’s warranty policy for their warranty
requirements and procedures.
No Implied Warranty of Fitness or Merchantability: There are no warranties that extend beyond the description on
the face hereof. Specifically, Mudd-Ox makes no other warranty of any kind, express or implied. All warranties of fitness
or merchantability for a particular purpose that exceed the obligations and time limitations specified in this warrant are
hereby disclaimed by Mudd-Ox and excluded from this warranty. Additionally, this warranty excludes any incidental or
consequential damages, including but not limited to loss of use. Some states do not allow a manufacturer to exclude or limit
incidental or consequential damages and, therefore, the above exclusion may not apply.
Some states do not allow limitations on how long an implied warranty will last. It is possible that the above limitation may
not apply. This warranty gives the original purchaser specific legal rights. The original purchaser may also have other legal
rights, which vary from state to state.
Warranty of Service: To obtain warranty service, the original purchaser must return the Mudd-Ox vehicle to the local au-
thorized dealer or service center, inform them of the warranty, and provide proof of purchase before any warranty service
can be provided. The authorized dealer or service center will inspect the product to determine what repairs or parts are
needed and whether they are covered under this warranty. To locate an authorized dealer or service center, please call
Mudd-Ox at [phone] or visit Mudd-Ox online at www.muddox.net

Safety
Safety Equipment
All occupants must wear a DOT-certified helmet. Standard are seat belts for the front two passengers, optional rear
with Twin Roll Bar and Seat - Bench. Use the seat belts at all times on land and ensure the ROPS (roll over protec-
tion system) system is in the upwards position with all pins and bolts correctly installed. Any time the vehicle is in
water, you must remove your seat belt and helmet, and wear a life preserver.
General Safety
Do not operate on public roads. Do not operate in waters with current or open water such as large lakes and oceans.
Do not refuel the machine with the engine running. Do not operate the Mudd-Ox on angles greater than 25 degrees.
Do not drive faster than conditions or your ability allows. Do not attempt to make sudden sharp turns or go from
forward to reverse abruptly; doing so could upset the machine or at the least jostle the occupants, possibly causing
injury.
Read through this entire manual and complete all necessary inspections, maintenance and parts replacements as
necessary.
• Do not operate this vehicle while intoxicated.
• Wear appropriate clothing: dress for weather conditions.
• Operator must be at least 16 years of age.
• Use common sense at all times while operating.
• Always have a first aid kit and fire extinguisher inside the vehicle.
• All passengers must be seated while the vehicle is in motion.
• Do not overload the vehicle under any circumstances.
• Ensure floor boards are in place while operating vehicle.
• Avoid blacktop when possible.
• Drive vehicle at safe speeds for terrain conditions.
Capacities of the Mudd-Ox
See Specifications for information on Mudd-Ox vehicle and Amphibious Trailer capacities. Under no circumstances
should the maximum capacities be exceeded. Subtract weight of all accessories from total vehicle capacities. Al-
ways evenly distribute weight to prevent imbalances.
Prepare Your Trip
The Mudd-Ox is capable of traveling to remote locations where emergency services are not readily available. These
locations can range from desert to tundra climates. When traveling in the Mudd-Ox, always pack a survival kit suit-
able for all occupants in the vehicle. This includes but is not limited to: food, water, extra clothing, fuel, flashlight,
portable heater, tent, flares, tools, spare parts, and spare tires mounted on rims. Never venture into remote areas
alone, and notify someone of your departure and expected arrival time. Create emergency plans in advance.

12
Safety Cont.
Every operator MUST review and understand the basic operation manual and all warning labels displayed on this
page and on the vehicle before operation. Please keep a copy in the glove box for operators to review as needed.

Wind chill is the feeling of colder temperatures than what the thermometer reads. This happens when the wind
blows cold air across exposed skin.
All Mudd-Ox operators and passengers must be aware of the wind chill factor. Always dress properly for the
weather and cover exposed skin. Ensure young children are adequately dressed for cold temperatures. It is best
to bring candles and blankets in case of emergency. For colder applications, we highly recommend installing either
our Cab - Canvas or Cab - Aluminum (Figure-1, 2) with a heater (Figure-3). For warm climates we recommend the
A/C Unit (Figure-4).

1. Parking brake light: Illuminates when the parking brake is engaged. This is required for the vehicle to start.
2. Engine low oil pressure warning light: Illuminates when the engine oil pressure is dangerously low. If illuminat-
ed, stop vehicle immediately and diagnose. Repair before operating again.
3. Ignition switch: When the key is installed, it will toggle the engine on and off. To start the engine: turn complete-
ly clockwise, release once started. Turn key to middle position to shut off engine. (If the engine fails to start after
5 seconds, see #4 to use the choke cable).
4. Choke Cable: Changes the air/fuel mixture in the carburetor. If the Mudd-Ox will not start with turning the key
switch, pull out the choke cable and attempt to start again. Push in once the engine has started and can maintain
idle.
5. Head lights switch: Flipping the switch to “on” will activate the headlights and tail lights. Never operate the
Mudd-Ox at night without lights.
6. Winch switch: Controls the direction of the winch motor. The “out” position will unreel the cable away from the
Mudd-Ox, while “in” will reel the cable towards the Mudd-Ox.
7. Heated throttle switch: In colder climates, the throttle cable may become frozen or hard to move. Simply
flipping the switch to “on” will activate the throttle cable heating system. Keep on until throttle works properly,
then flip switch to “off.”
8. Bilge pump switch: When in an emergency, if the Mudd-Ox has water in the lower body, quickly flip on the bilge
pump switch. This will immediately begin to pump water out of the vehicle. Caution: This is a feature to remove
small amounts of water. If the machine is completely filled, you must quickly exit quickly.
9. Auxiliary switch: Additional switch to be used with Mudd-Ox accessories such as a powered dump bed or lights.
If no additional accessories have been installed, the switch will not operate anything.
10.Auxiliary switch: Same as #9.
11. USB ports: Under the weatherproof cover are (2) 12v USB ports. These may be used to power accessories such
as a cell phone.
12. Cigarette lighter port: Under the weatherproof cover is a 12v cigarette lighter port. This may be used to power
accessories such as a cell phone.
13. Voltage meter: This electronic unit displays vehicle voltage. A non-running engine will show approx. 12.7 Volts,
while a running engine should show approx. 13.8 Volts. If engine voltage is severely below 12.7, it may be nec-
essary to charge the battery and immediately diagnosis if the battery or charging system is faulty. If alternator
outputs significantly over 13.8 volts, diagnose charging system immediately to prevent over charging of battery.
14. Fuel gauge: The fuel gauge monitors the amount of fuel left in the vehicle. When traveling to remote locations,
the vehicle should always be filled with additional fuel cans in case of emergency. Leave enough fuel to return
back to your starting location.
15. Transmission oil temp gauge: The oil gauge monitors transmission oil temperature, and must not exceed 190
degrees Fahrenheit. If the temperature exceeds 190 degrees, immediately stop driving. Leave the Mudd-Ox on
to allow the transmission cooling system to operate.
16.Engine oil temp gauge: This monitors the temperature of the engine oil, and must not exceed 300 degrees
Fahrenheit. If the temperature exceeds 300 degrees, immediately shut off and diagnose.
