SAFETY CONVENTIONS
WARNING: This indicates a hazardous situation, which, if not avoided, could result in
death or serious injury.
CAUTION: This indicates a hazardous situation, which, if not avoided, could result in
minor or moderate injury.
NOTICE: This information is important in proper use of your machine. Failure to follow
this instruction could result in damage to your machine or property.
ADDITIONAL INFORMATION AND POTENTIAL CHANGES
We reserve the right to discontinue, change, and improve our products at any time without
notice or obligation to the purchaser. The descriptions and specifications contained in this
manual were in eect at printing. Equipment described within this manual may be optional.
Some illustrations may not be applicable to your machine.
IMPORTANT SAFETY CHECKLIST
Trailers are generally not used everyday. Your trailer may sit for extended periods of time
between uses making it very important to check all components thoroughly before each use.
Following these simple instructions will maximize the life of your trailer and help you safely
transport cargo.
CAUTION: DO NOT ABUSE THE TRAILER.
Trailer performance is best if you follow the guidelines set forth in this manual. Do
not force the trailer to do a job it is not designed for. Know your trailer; learn its
applications and limitations.
1. Make sure the towing vehicle as well as the hitch are capable of towing the trailer. Check
your vehicle owner’s manual for trailering things.
2. Inspect the trailer and all of its parts before each use.
3. Check the operation of all lights. Operating lights are mandatory on a trailer.
4. Check to ensure wheel bolts are tight. Torque to 80 ft.-lbs. Re-tighten after the first 50
miles (80km).
5. Check the tire pressure. Maximum 80PSI (552KPA) when carrying the maximum rated
load.
6. Re-pack the wheel bearings every 2,000 miles (3,200km) or a minimum of once every
year.
7. Check that the trailer coupler is fastened securely onto the trailer ball. The trailer ball
must be a 2-inch ball.
8. Make sure the safety chain is attached to the trailer and the towing vehicle.
9. If your trailer has an optional side kit, make sure all bolts and pins are in place before
transporting your trailer.
10. Do not exceed the Gross Vehicle Weight Rating (G.V.W.R.) which is shown on the trailer
serial/certification label.
11. Balance and secure the load on the trailer. See “Trailer Loading” section in this manual.
ENGLISH

12. Lubrication of the coupler, springs, and the tilt mechanism should be done periodically to
stop corrosion and keep parts moving freely.
DANGER: KEEP CHILDREN AWAY
Be sure children are kept a safe distance from the trailer operating area.
DANGER: NEVER SIT OR RIDE ON THE TRAILER
Serious injury or death could occur.
DANGER: EXERCISE EXTREME CAUTION WHEN TILTING THE TRAILER
There are many areas of the trailer where injury can occur if used improperly. The trailer
may tilt quickly and unexpectedly during the loading and unloading process. The tilt
option should not be used for heavy loads.
DANGER: Ramps should be used for loading heavy items.
DANGER: Do not drive with the trailer in the tilted position.
DANGER: Do not load more than one all-terrain vehicle onto this trailer.
DANGER: If the trailer is incorrectly attached to the vehicle, it could pull away from the
vehicle and fall o.
DANGER: Secure the trailer to the towing vehicle before transportation. Make sure
coupler is locked and the safety chains are attached to the trailer and the vehicle.
DANGER: Secure your cargo into the trailer properly and in compliance to local laws.
DANGER: When driving do not exceed the speed limit. Braking time can be considerably
longer when a vehicle is towing a loaded trailer.

WIRING LEGEND
SYMBOL COLOR DESCRIPTION OPERATION
G Green Wire Passenger Side (Right) Right Signal Brake
B Brown Wire Running Lights Tail Light Marker Yellow Front Side Markers
Y Yellow Wire Driver Side (Left) Left Signal Brake
W White Wire Ground Trailer Ground
NOTE:
• Brake light goes out on the side that is signaling.
• Lower Filament (Brighter light) = Brake & Signal.
• Higher Filament (Dimmer Light) = Running Lights
TO TEST VEHICLE WIRING:
You will need a 12v light tester. Attach the wire clamp of the tester to the ground wire on the
vehicle plug. Then touch the tester pin into one of the vehicle plug contacts. Turn on the
corresponding vehicle operation i.e. Running Lights. This will illuminate the tester light if the
vehicle wiring is correct. Follow this same procedure for the signal and brake lights.
TO TEST THE TRAILER WIRING:
Once you have confirmed that the vehicle trailer plug is operating properly, connect the trailer
plug into your vehicle. To proceed to test each of the lights and power leads using your 12v light
tester. Follow the wiring legend and diagram to test each corresponding wire for power when
the trailer light is not operating.
NOTICE: Always be sure to check your brake, running and signal lights before each use.
Make sure that all of your connections are solid and that all wiring is in good condition.
NOTICE: Bare, stripped, or pinched wire will cause a short in the trailer, which will cause
the vehicle fuse to blow. A solid ground is required for your lights to work properly. All
contacts must be to bare metal. Light covers should be well maintained and kept clean.
Be sure that your lights are always visible, not obstructed by your load.
LOADING YOUR TRAILER
a) Distribute the weight evenly.
b) Center the load over the axle, keeping about 10% of the weight on the tongue. (If vehicle
wheels are not on a crossbeam you will need to add wood to the floor to support each
axle.
c) Center the load from side to side.
d) Always secure your cargo into the trailer properly and in compliance to local laws.
CAUTION: Do not build your trailer load higher than 3 feet. Higher loading will aect
trailer handling due to increased wind resistance. This may cause violent movements,
accidents and serious injury.
ENGLISH

10 | MMT4X6OG man.
CAUTION: TRAILER CAPACITY
• Never overload your trailer. Each trailer has a maximum payload that should not be
exceeded. Overloading your trailer could cause serious damage to your trailer as well
as the towing vehicle. Please refer to your trailer serial/certification label located on the
same frame of the trailer for capacity details.
• The Gross Vehicle Weight Rating (G.V.W.R.) is the weight of the trailer + the maximum
payload the trailer can carry. The trailer weight and the payload must not exceed this
weight rating.
• Be sure that any load carried in your trailer does not extend beyond the frame of your
trailer. Never place loads on one side only.
CAUTION: TONGUE WEIGHT
• The tongue weight is 10% of the load (this does not include the weight of the trailer).
• The load is divided so that 90% of the load is over the axle and 10% is over the tongue.
TRAILER COUPLER
LOCKED UNLOCKED
TO ADJUST COUPLER TO BALL:
Set the coupler and tongue onto the 2-inch trailer ball on your vehicle. Raise the locking lever,
push up on the channel lock and turn nut to tighten or loosen the coupler. Proper adjustment is
obtained when the coupler is as tight as possible on the ball and the locking lever can still be
opened and closed.
NOTICE: Before towing your trailer be sure to check the capacity of your trailer hitch
on your vehicle (never exceed this or your trailer’s capacity).
The DK2 Inc. Trailer is equipped with a 2-inch coupler and must be used with 2-inch
trailer ball. Make sure that the trailer ball is completely engaged in the coupler ball.
