Setup and Operation Instructions
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the
beginning of this manual including all text under subheadings therein before
set up or use of this product.
TO PREVENT SERIOUS INJURY AND DEATH:
Before loading or unloading turn vehicle’s engine off, set its transmission
in gear or park, engage its emergency brake and block its wheels.
Make sure the Ramps are clean and dry before loading or unloading.
Setup
CAUTION! Unfold both Ramps completely,
being careful not to pinch your hands.
WARNING! TO PREVENT SERIOUS
INJURY: Connect Safety Straps (3) to
secure attachment points within the
truck bed able to withstand the pulling
force of loading. They must also be
tight enough to prevent the Ramps from
coming off the vehicle being loaded.
1. The tailgate and the Ramps must
be dry and clean. Check for and
tighten any loose hardware.
2. Sit the Tongue (angled lip) of the
Ramps on the tailgate. The Tongue
must face down, and fully contact
the truck’s tailgate. Extend the
Safety Strap (3) on each Ramp
up into the inside of the truck bed;
attach each Safety Strap to a secure
attachment point on the truck chassis.
Safety
Strap (3)
Tongue
(angled lip)
3. Pull the Ramps backwards
until the Straps are tight.
The entire Tongue portion of the
Ramps must fit onto the tailgate; if not,
adjust the Safety Straps accordingly.
Note: Store Safety Straps indoors after use.

Page 6 For technical questions, please call 1-888-866-5797. 63772
Safety Strap Adjustment
1. Loop the Safety Strap through
the anchoring point on the
truck and hook it to itself.
2. Adjust the other Safety
Strap to equal length.
4- Wheel ATV Loading and Unloading
• These Ramps are for use with 2-wheeled dirt bikes and 4-wheeled ATV’s only.
Do not use these Ramps to load/unload 3-wheeled vehicles.
• Do not use these Ramps to load or unload any vehicle that weighs more than 1400 lb.
• Do not use these Ramps to load or unload any vehicle with wheel width wider than the
Ramp.
• Do not use these Ramps to load or unload any vehicle that is carrying gear on its racks.
• Do not use these Ramps if the tailgate on the vehicle being
loaded or unloaded is higher than half each Ramp’s length (42″).
WARNING! TO PREVENT SERIOUS INJURY: Riding an ATV while loading or unloading
is dangerous and should not be attempted.
WARNING! Be aware of dynamic loading! Sudden load movement may briefly create excess
load causing the Ramps to fail.
WARNING! TO PREVENT SERIOUS INJURY: All persons not involved in the process must
stand clear of the Ramps and truck. Make sure no pets are nearby.
Loading Using a Winch (not included)
1. The winch and mounting/connection
points must all have appropriate capacity
to pull the ATV up the Ramps safely.
2. ATV Mounted Winch Setup:
Unwind cable from the winch and attach
it to a secure mounting location on the
truck, at the same height as the winch
will be after the ATV has been loaded.
3. Truck Mounted Winch Setup:
Attach the cable to the bottom
front part of the frame.
4. While operating the winch,
stand back and to the side of the
ATV, with the vehicle between
you and the winch cable.
5. Operate the winch to slowly load
the ATV onto the vehicle.
Unloading
WARNING! TO PREVENT SERIOUS
INJURY: Riding an ATV while unloading is
dangerous and should not be attempted.
1. Have an assistant monitor the Ramp
tongues for slippage on the tailgate.
2. Setup the Ramps on the truck
bed as explained under operation.
Remove all tie down straps and
securing equipment from the ATV.
WARNING! TO PREVENT SERIOUS
INJURY: Be sure the 4-wheel
ATV is centered on Ramps.

Page 7For technical questions, please call 1-888-866-5797.63772
3. While staying off the ATV, start the engine,
disengage the parking brake, put the
transmission into reverse, and make
sure the wheels are in a straight line with
the Ramps. While holding the brake,
position yourself in front of the ATV.
4. Release the brake and push on the ATV to
get it started down the Ramps. Allow the
ATV to roll down naturally, do not steer it
or apply the brakes. If it stops while on
the Ramps, gently give it throttle to back
it off the Ramps.
2-Wheel Dirt Bike Loading
1. Do not attempt to load any dirt bike
or other 2-wheel motor bike alone.
Have a qualified adult assist.
2. Line up the 2-wheel dirt bike
with one of the Ramps.
3. With one person pushing the dirt bike
slowly up the Ramp, a helper
should be in the bed of the hauling
vehicle both to guide and to apply
the brake if it is necessary to stop
the dirt bike while it is on the Ramp.
Have one person with a hand on the
dirt bike hand brake for safety.
4. Once the person inside the truck bed
has hold of the handle bars, apply
the brake and steady the dirt bike
while the other person moves behind
the dirt bike (but off to one side) and
pushes it all the way into the truck bed.
NOTE: While most dirt bikes are light
enough to safely load with two people, a third
person can make the job easier and safer.
5. Once the dirt bike is safely loaded,
secure it with four tie down straps
(not included), one on each side
of the front, and one on each side
at the rear of the dirt bike.
2-Wheel Dirt Bike Unloading
1. Position the Ramp against the
truck tailgate behind the rear tire
of the dirt bike and attach the
Safety Straps to the truck bed.
2. Remove the tie-down
straps (not included).
3. Slowly and carefully while using
an assistant, push the dirt bike
backwards until the back tire is at the
top of the Ramp. With one person
on the ground behind and to the
side of the Ramp, slowly push the
dirt bike onto the Ramp. Someone
must always hold the hand brake.
4. Slowly work the dirt bike down the
Ramp and onto the ground.
