Read These Important Rules for Safe Operation
NOTE: All the items (1-33) below should be read and understood
by the Operator and Parent. Failure to follow these
instructions could endanger the personal safety of the
operator and/or any passenger.
1. This vehicle is not licensable. IT IS NOT TO BE OPERATED ON ANY PUBLIC ROAD, STREET,
SIDEWALK OR ALLEY. To do so would be a violation of local law. This vehicle may be operated
only on private property and upon areas approved by local law.
2. This vehicle should NEVER be operated indoors. The exhaust from the engine contains carbon
monoxide, which is a tasteless, odorless, and poisonous gas.
3. This Fun-Kart is not intended nor designed for racing.
4. The operator of this vehicle should always wear a D.O.T. approved helmet and other protective
equipment as recommended by state and local laws. The operator should also wear a face
shield or goggles, boots, gloves, and other appropriate protective clothing.
5. Unless otherwise specified in this manual, all screws, nuts, and bolts must be kept tight to ensure that
the vehicle is in safe operating condition. The engine must be kept free of all dirt and other
accumulations, paying particular attention to the throttle linkage area.
6. Prevailing Torque type locknuts lose their locking capability with repeated use and require
replacement. Ensure locknuts are functioning properly.

1-888-962-6554 www.YERFDOG.Com

7. The tire pressure should be checked prior to each use. The recommended inflation pressure is the
maximum tire pressure, which is printed on the tire’s sidewall. Improper tire pressure may cause
instability and may prevent proper braking or steering.
8. Modification of this vehicle or removal of any original equipment or safety decals may render the
vehicle unsafe or illegal. Never remove the chain guard, or belt clutch guard. These covers are
for the riders’ protection.
9. The vehicle should never be started without first checking to see that the throttle is in the idle position.
Do not start engine without verifying proper function of the throttle.
10. Never attempt to start this vehicle without having the operator sitting in the proper position to
ensure control of the kart.
11. The operator’s ability to operate this off-road vehicle safely is largely dependent upon the operator’s
ability to exercise proper judgment. An operator also must not be too small or too large for controlled
operation. The operator must be at least 16 years of age and having understanding, mental capacity,
and physical capability to safely operate this vehicle. This vehicle should only be operated after
mature, supervised instruction and sufficient practice in non-congested areas. Safe operation
includes responsibility for the safety of a passenger.
12. This vehicle is designed for one operator and one passenger. A passenger on any vehicle must
be sufficient age, understanding, mental capacity, and physical capability to act to protect
himself/herself, and wear a D.O.T. approved helmet at all times. This kart is not recommended for
cumulative weights exceeding 150 pounds.
13. The engine should be stopped when the vehicle is not in use.
14. Loose clothing, long hair, or articles worn by any riders must be fully contained, or covered to
prevent them from possibly being caught in rotating parts of the vehicle or the surrounding
environment while riding. Failure to obey could endanger the personal safety of the riders.
15. Do not place hands, feet, or any other part of the body or any clothing near the engine,
muffler, wheels, chain, and other rotating parts of the vehicle while riding or running the
engine. Caution must be used in performing required maintenance on or near an operating engine.
Special caution should be taken after the engine has been running, since the engine and other drive
components may be extremely hot.
16. Wet, slippery, rough, or steep terrain is potentially dangerous and may result in injury if proper caution
is not observed. Slow speeds are required to safely operate this vehicle under those conditions. The
operator must use mature judgment, skill, and experience to choose a speed suitable for the terrain
and riding conditions.
17. The Governor settings for this vehicle’s engine must not be tampered with, altered, or
changed. The governor is set by the engine manufacturer and limits the maximum speed of the
engine (and vehicle) and protects the engine from damage. Excessive speeds are potentially
dangerous to the rider and the engine.
18. Each time before using this vehicle, the fuel supply should be checked. The fuel tank should never
be filled while the engine is running or while the engine is hot. Do not fill tank in closed area such as
a garage, while smoking, or in the vicinity of an open flame. Do not overfill the tank. Always allow at
least ¼ inch of space at the top of the tank for expansion. Never top off tank. Replace cap tightly to
prevent spillage of fuel and potential fire hazard. After filling tank, move the vehicle at least 15 feet
away from spot of filling before starting.

1-888-962-6554 www.YERFDOG.Com

19. If the vehicle should start making unusual noise or vibrating abnormally, the engine should be
stopped and the spark plug wire disconnected. The vehicle should then be checked for damage.
Excessive noise or vibration is generally a warning of loose or worn parts.
20. When making repairs or adjustments to the vehicle which do not involve adjustments to the engine,
the spark plug wire must be disconnected and kept away from the spark plug to prevent accidental
starting. When working on or around or when restarting engine, use extreme caution to avoid contact
with the muffler, cylinder head, or any other potentially hot area on or around the engine.
21. Always perform a Pre-Ride Inspection before starting the engine. See Pre-Ride Inspection in the
manual.
22. The custom brush guard assembled on this vehicle is for deflecting loose vegetation and must not be
removed.
23. When storing the vehicle, it must be kept in a place where gasoline fumes will not reach an open
flame or spark. For long periods of storage, such as for winter, the fuel tank should be drained an
open cool area. The engine must be allowed to cool before storage in any enclosure. Read and
keep all printed material supplied with this vehicle. Timely and specific instructions and Operator’s
Manual revisions are included in supplements. If any printed material included is unclear, please call
1-888-389-5522 for assistance.
24. Never operate this vehicle while under the influence of alcohol, drugs, or medication of any
kind. Such operation could be dangerous to you and/or others.
25. Always slow down while turning. High speed turning may cause loss of control, and increases the
possibility of injury to the operator.
26. Do not race, jump, or perform “stunt” riding or “spinouts” while operating the Fun-Kart. The
Fun-Kart is not designed or intended for such operation.
27. This manual provides guidelines for the assembly, maintenance, and operation of this Fun-Kart and is
not intended as a service manual.
28. Assembly, maintenance, and/or repair of this Fun-Kart should only be performed by persons of
sufficient mechanical skill, experience, and judgment (such as outdoor equipment dealers, motorcycle
dealer/shops, or small engine dealers) so that no unsafe condition or modification is made.
29. Always use extreme caution when starting the engine. Avoid touching the engine, muffler, or drive
components. These areas could cause burns on contact.
30. Operator must always be appropriately supervised at all times while operating this vehicle.
31. Riding your Fun-Kart requires skill acquired through practice over a period of time. Take the time to
learn the basic techniques before attempting to ride the vehicle.
32. Ride only on safe and familiar terrain. Avoid loose gravel and rocks. Be careful on wet surfaces and

6. Bolts –Check the screws, nuts, and bolts on your vehicle to see that all are tightened securely. For
safe operating conditions, do periodic checks and tighten securely.
7. Engine –Fill the crankcase with oil until it reaches the FULL mark on the dipstick. DO NOT
fill above the FULL mark. Approximately 20 oz. or 1¼ pints (.6 liters) of SAE 30 weight oil. For
additional information refer to Tecumseh engine manual for servicing the engine.
8. Fill fuel tank with regular gasoline, leaded or unleaded. Do not use premium gasoline. Do not
overfill (No fuel in filler neck).
9. Tire Pressure
CHECK AIR PRESSURE IN TIRES!!
It is common industry practice to over inflate the tires. This is done to guarantee an airtight seal. Prior to
riding the Fun-Kart for the first time, you may need to reduce the air pressure in the tires to specifications
stated below:
Rear Tires 20 PSI
Front Tires 20 PSI
Proper tire pressures will increase the life of the tire and enhance the performance of the Fun-Kart.
Driving on asphalt or concrete will significantly reduce the life of the tires!!

PRE-RIDE INSPECTION
WARNING –Perform this pre-ride inspection everyday before riding the
vehicle. If not performed, serious damage to vehicle and
personal injury may result.
1. Engine Oil Level –Add oil if required. Check for leaks. Tighten filler cap securely.
2. Fuel Level –Add fuel if necessary. Do not overfill (no fuel in filler neck). Replace cap tightly. Check
for leaks. Do not mix oil with gas. Only refuel when engine is off and cool.
3. Brakes –Perform a Brake Test: Sit in the vehicle with the brake actuated by pressing on the brake
pedal. Start the engine with the ignition switch on. Increase the engine RPM gradually to ensure that
the brake is effective. Do not operate this Fun-Kart unless the brake is working properly.
4. Tires –Check conditions and pressure.
5. Drive Chain –Check condition, tension, lubricate as necessary.
6. Throttle –Check for smooth operation. Assure throttle “snaps” back to idle. Also, check for frayed
cable or damaged able conduit. If either condition exists replace the cable assembly before riding.
7. Stop Switch –Perform this stop switch test. While the engine is running, move the steering column
remote stop switch to the “OFF” position. If this does not stop the engine, move the engine remote
switch to the “OFF” position. If the engine is not equipped with an engine remote switch, pull the
spark plug wire. Check to insure that the stop switch wire is attached to the terminal on the engine.
Do not operate this vehicle with a stop switch that is not functioning properly.
8. All Nuts, Bolts, and Fasteners –Check wheels to insure that all axle nuts and lug nuts are tightened
properly. Check and tighten all other fasteners as necessary. Regularly check set screws on
sprockets and drum.
9. Guards –Ensure all protective guards are in place. Never remove the chain guard, or clutch
guard. Each of these covers have a protective purpose, if removed it could endanger the personal
safety of the operator or passenger.
10. Steering System –Ensure that it turns freely.
STARTING INSTRUCTIONS
NOTE: Do not attempt to start or operate this vehicle without being
completely familiar with all controls necessary to operate this
vehicle safely. Do not start the engine before reading and
understanding all the rules, warnings, and instructions in this
manual.

1-888-962-6554 www.YERFDOG.Com

1. Before starting the engine, the operator should be seated in the Fun-Kart. If the rider is not seated in
the vehicle, it should be placed against a stationary object and started.
2. Do not start the engine before checking to make sure the throttle assembly is in the idle position.
Warning –Each time prior to starting the engine, check throttle assembly to ensure that when the
throttle pedal (right side) is pushed all the way forward the assembly is working smoothly and returns
to idle when released. Do not operate if pedal and engine throttle linkage fail to return to idle.
3. To start a cold engine, pump the engine primer “3” times. If the engine is hot, priming may not be
necessary to restart the engine.
4. Pull recoil starter rope sharply. See Tecumseh engine owner’s manual. Do not flood the engine by
continuously pulling the starter rope. If engine does not start after two or three pulls of the starter
rope, wait a few minutes then repeat the above procedures.
OPERATIONAL SAFETY TIPS
TURNING MANUEVERS
The new rider must learn to shift his weight and control the throttle to allow the rear tires to negotiate the
turn. This is the primary technique to be mastered in riding this vehicle. Practice turning at a slow
constant speed. Defer increased speeds until you are confident of your proficiency and are intimately
familiar with the terrain.
Steer in the direction of the turn, and lean your body to the inside of the turn in order to maximize front tire
traction. Use the throttle to maintain posture throughout the turn.
Incorrect turning techniques may cause the front tires to slide straight ahead without affecting the vehicles
direction of travel. If this should occur, come to a stop, then resume the technique outlined above.
If the front wheels tend to skid in mud, sand, or snow, you may be able to improve control by releasing
the throttle and allowing the vehicle to coast through the turn.
If the rear wheels inadvertently skid sideways, correct your slide by steering in the direction of the skid, if
you have room to perform this maneuver safely. Avoid braking or accelerating until you have control.
To avoid skids while traveling on slippery terrain, the rider must exercise a high degree of caution.
Turning maneuvers on slippery terrain are more hazardous than those performed under full traction and
must be done slowly.
PREVENTIVE MAINTENANCE
STORAGE
In the event your vehicle is not to be operated for a period in excess of 30 days, or at the end of riding
season, prepare for storage as follows:

1-888-962-6554 www.YERFDOG.Com
10
WARNING –Do not drain fuel while engine is hot. Be sure to move vehicle outside
before draining fuel.
1. Drain fuel tank and remove all fuel remaining in the tank by using a suction device or by soaking up
the fuel with a clean rag or towel. Remove all fuel remaining in the carburetor by allowing the engine
to run out of fuel. Do not perform any fuel removal procedure while smoking or near an open flame.
Dispose of any rags or towels properly.
2. Lubricate engine cylinder by removing the spark plug and pouring an ounce of lean lubricating oil
through the spark plug hole into the cylinder. Crank the engine slowly to spread oil and replace spark
plug.
3. Do not save or store gasoline over winter. Using old gasoline that has deteriorated from storage will
cause hard starting and affect engine performance.
4. When the vehicle is removed from storage re-read the owner’s manual, perform any assembly
required, and perform a pre-ride inspection. See Pre-Ride Inspection section of this manual.
GENERAL
Just as your automobile needs professional, mechanical maintenance from time to time, so does this
vehicle. Replacement of the spark plug and ignition points is made necessary by normal use.
Professional air-cooled engine service is easily obtained. Check your phone book yellow pages under
“Engine Gasoline”.
SERVICE INSTRUCTIONS
Engine Lubrication –You must change the oil in the crankcase after the first two hours of operating your
new engine and after each 25 hours of use thereafter. That will insure proper lubrication in internal parts
and prevent costly repairs due to excessive wear. Refer to Engine Maintenance Instructions.
Kart Lubrication –Every two or three hours of use lubricate the following items with several drops of oil;
steering bearing points, brake rod pivot points, pedal pivot points, steering spindles, and steering rod
ends. Use the same grade of lubricating oil that is used in the engine crankcase.
Chain Lubrication –For the best chain life, it should be lubricated with a graphite type of lubricant
such as the spray-on type that evaporates leaving the graphite on the chain. Using oil or grease on
the chain in dusty or sandy riding conditions may cause dirt particles to stick to the chain resulting in rapid
wear from abrasion.
Front Wheel Replacement –Care must be used when replacing wheels. Do not over tighten nuts. It is
only necessary to tighten the nuts so that the wheel turns freely on the axle with minimum endplay. If the
wheel does not turn freely the nut is too tight.
Rear Wheel Replacement –Loosen the large locknut in the center of the wheel to remove the rear wheel.
Chain Adjustment –After the first two hours of operation, check the chain adjustment and readjust it if it
has more than ½” flex. Loosen the engine clamp nuts and slide the engine forward to tighten chain.
