WARNING: FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN LOSS OF TOWING VEHICLE CONTROL,

SEPERATION OF THE TOW DOLLY FROM THE TOWING VEHICLE, SEPERATION OF THE TOWED VEHICLE FROM
THE TOW DOLLY, CAUSING SEVERE PERSONAL INJURY, DEATH, OR PROPERTY DAMAGE.

SAFETY

Safety is of utmost importance at all times. There are
several items that must be checked each time before
using and while using the Kar Kaddy.

Rear Wheel Drive: Disconnect the towed vehicle
driveshaft for rear wheel drive vehicles with automatic
transmission.
For manual transmission: Consult your vehicle owners
manual for towing suitability with the drive shaft connected.

Make sure all bolts are properly tightened and those
requiring a set torque are up to specifications:
Tie Rod Castle Nut - 75 ft./lbs.
Lug Nuts - 75 to 80 ft./lbs.
Check Lug Nut tension after the first 5 miles and
periodically thereafter.

Periodically check all bolts and nuts to insure proper
tension or torque.

The ball hitch must latch securely around the ball and
the safety lock pin or lever must be in position to lock the
hitch on the ball.
RECOMMENDED BALL HEIGHT: 18 inches to the top
of the ball on the towing vehicle.

An occasional drop of oil may be required on the moving
parts of the tie down winches.

Hook the towed vehicle safety chains to the frame of the
vehicle directly above the area where the chain is
mounted on the Kar Kaddy. Leave some slack in the
chain to allow suspension movement.
Check to make sure that all lights are in proper working
order.
Examine the winches and straps, making sure they are
in good conditon.
Be certain the safety lock pins are locking the strap
winches.
Retighten straps over the tires after the first 5 miles and
every 50 miles thereafter. Ensure that they are tight.
The KK260 tires must be inflated to the recommended
50 PSI.

MAINTENANCE

Grease the king pin and tie rod end grease zerks every
2500 miles.

A light film of oil should periodically be applied to steering
stabilizer arm to prevent rust.
NOTE: Proper toe-in is 1/32". This is preset at the
factory.
The operator should periodically have the toe-in checked
and adjusted if needed at a qualified alignment shop.
Improper toe-in can result in irregular tire wear.

IMPORTANT LOADING INSTRUCTION
Check your wheel tie-down straps.
Your Kar Kaddy is equipped with custom made
wheel tie-down straps of a standard size that will fit
most tires, however if your tires are too large or too
small you will want to exchange these new straps
for the proper size straps.
1. Tire too large - This is very obvious the strap
will not basket over the tire properly, call us,
we will provide at NO Charge on an exchange
basis, the proper size strap. You must return
your new unused straps and provide us with
the Make and Model car and the tire size.

The KK260SB, KK360 and KK360SB tires must be
inflated to the recommended 50 PSI.
The strap on the optional tongue winch must be in good
condition and should be stored neatly on winch when
not in use.
NOTE: The winch strap must not be left connected to
the towed vehicle after it is loaded and strapped down.
Make sure the optional light bar is fastened securely at
the rear of the towed vehicle.
The wires to the optional light bar should be run along the
car and fastened so as not to damage the finish of the
towed vehicle.
NOTE: This unit cannot be backed up, when loaded or
with the steering lock pin removed.
All vehicles mounted on the Kar Kaddy must be mounted
with the front of the vehicle facing forward.

2. Tire too small - This is not as obvious, the
basket will fit down over the tire very well, the
problems cannot be readily seen. You must
tighten the straps down solid and then check
on the inside of the tire and be sure the strap,
when tightened does not come in contact with
any metal that may cause wear or cutting such
as strut mounts. If there is contact, you need a
smaller strap, call us, we will provide on a NO
Charge, exchange basis, the proper size strap.
You must return your new unused straps and
provide us with the Make and Model car and
tire size.
Thank you for Purchasing
Products.

TESTING LIGHTS BEFORE USE
1. Check that the WHITE (ground) wire of the wiring harness
is connected to the Kar Kaddy frame and the WHITE
(ground) wire is connected to the frame of the towing
vehicle.
2. With headlights in "ON" position, the tail lights, the light
cluster bar, the license plate light, and the clearance lights
should be lighted.
3. Start engine and have someone depress brake pedal.
Brake lights of tow dolly and towing vehicle should come
"on" and "off" simultaneously with each application.
4. Turn left turn signal on. Left turn light of Kar Kaddy and
towing vehicle should flash simultaneously. Should the
turn signal lights of the trailer function opposite to those of
the towing vehicle, it is probable that the YELLOW (Driver
side) and GREEN (Passenger side) wires have been
reversed. Check the plug connection under the tongue of
the Kar Kaddy to make sure wire colors are not crossed at
that point. If plug connection is incorrect, correct problem
by reversing yellow and green wire connection on the
towing vehicle.

Step 3. Loosen wing nut on back of license plate holder, turn
the clip on the front to a horizontal position and put license in the
"down" position. Turn the clip back so it rests against the back
of the light bar to hold the license down and tighten wing nut.
(License must be "UP" with the tow dolly empty).

LOADING INSTRUCTIONS
Refer to load limits on inside of front cover.

Step 1. Secure ball coupler to 2" (5,000 lb. capacity) towing
vehicle ball only. Make sure that the hitch and the hitch ball
are in good condition and not rusted, loose or stripped.
Recommended ball height is 18" to the top of the ball.
Make sure hitch is locked down and secured with safety clip.
Criss-cross safety chains under tongue and secure to towing
vehicle frame.

Step 4. Before loading (and unloading) towed vehicle make
sure platform and towed vehicle are in straight alignment. Tow
dolly must be completely and properly hooked up to the towing
vehicle. Towing vehicle must be larger and at least 1000
lbs. heavier than the tow dolly and towed vehicle combined.

Step 2. Remove black locking pin BEFORE loading vehicle
onto the Kar Kaddy. The removal of the locking pin allows
"Auto Steer" to operate. When towing the dolly empty, this pin
must be in place.

IMPORTANT: Tire tread width or body width of towed
vehicle must not exceed:
KK260 - 70" max. (outside to outside),
42" min. (inside to inside),
72" max. (body width).
KK360 - 76" max. (outside to outside),
42" min. (inside to inside),
78" max. (body width).

Step 7. Drive vehicle onto the platform - front forward - until
tires touch the wheel stops at the front of each side of the
platform and the platform tilts to a flat position. Make sure the
car is centered on the platform. Towed vehicle tires must fit in
wheel troughs without overhanging sides. Engage towed
vehicle parking brake. Shift loaded car into "park" and lock
steering wheel with front tires in a straight position. If the car
does not have a locking steering column the steering wheel
must be tied securely with front tires in a straight position.
Rear Wheel Drive: Disconnect towed vehicle driveshaft for
rear wheel drive vehicles with automatic transmission.
For manual transmission: Consult your vehicle owners
manual for towing suitability with the drive shaft connected.
Step 5. Grasp bed release handle on tongue and pull
toward coupler. This releases the tilt bed to permit loading.

Step 8. Place one tie-down strap over each tire and secure
hooks to rods located at the rear of each wheel platform. The
short side of the hook must face the rear of the Kar Kaddy.

Step 6. With someone safely guiding you, slowly drive veStep 9. Be sure tie-down winch is centered with the tire before
hicle onto platform FRONT FORWARD. (Any vehicle mounted
tightening straps.
on tow dolly must be mounted with front of the vehicle facing
forward.) Drive the car forward until the tires touch the ramps.
Make sure the tire is aligned to ascend onto the ramps.

Step 10. Thread tie-down strap through the slotted tube on the
tie-down winch. Pull approx. 6" of strap through this slot.
Begin tightening strap making sure the tail becomes enclosed
by the strap coming over the tire. Tighten the straps ensuring
that the strap fed through the slot binds between the shaft and
the strap being wound onto the winch shaft. While tightening
straps, pull cross strap forward to ensure even tightening.
NOTE: Be sure to tighten straps until each tire starts to
flatten against tire stop. After each strap is tight, insert a
safety pin in each winch. Disengage towed vehicle parking
brake.
Straps must be retightened after first 5 miles of travel. Check
straps every 50 miles thereafter to ensure they are tight and
not rubbing or fraying.
Step 11. Make sure the tie-down strap is the correct size for
the auto tire. See page 11 of this instruction for proper fit and
exchange instructions.

Step 13. TO UNLOAD towed vehicle. Make sure that platform and vehicle are straight. Reinstall driveshaft. Ensure that
towed vehicle parking brake is fully engaged, then unhook the
towed vehicle safety chains, and release the tie-down straps.
NOTE: Tie down straps must be "quick -released" by grasping
ratchet pawl (A) and ratchet handle (B) simultaneously and
pushing down sharply. This process will permit easy removal
of strap from winch.Swing the wheel platform locking latch
handle forward, towards the coupler. This will allow the
platform to tilt as you slowly drive off. Make sure the winch
ratchet handles are horizontal. Replace the "Auto Steer"
locking pin (for towing empty).
Step 14. To pull the Kar Kaddy empty, make sure "AutoSteer" LOCKING PIN IS IN PLACE and towing vehicle
safety chains are up and hooked. Tie-down winch handles
should be left in a down postion (horizontal) position with
safety pins in place when towing loaded or empty. DO NOT
ATTEMPT TO PULL KAR KADDY WITH WHEEL PLATFORM IN LOADING (tilted) POSITION.

DAMAGE PREVENTION
Check your vehicle manual or registration for vehicle weight.
Towing vehicle must be larger and at least 1,000 lbs. heavier
than the towed vehicle and tow dolly combined.
Do not pack goods in car that is being towed. Overloading the
Kar Kaddy or exceeding the width limit may result in damage
to both car and Kar Kaddy.

REAR WHEEL DRIVE PRECAUTIONS

Step 12. Hook the towed vehicle safety chains to frame of
vehicle directly above the area where the chains are mounted
on the Kar Kaddy. Leave some slack in the chains to allow
suspension movement of the towed vehicle.

Disconnect towed vehicle driveshaft for rear wheel drive
vehicles with automatic transmission. Simply placing transmission in neutral is not sufficient to prevent damage to
transmisssion.
For manual transmission: Consult your vehicle owners manual
for towing suitability with the drive shaft connected.
ALL VEHICLES MOUNTED ON THE KAR KADDY MUST BE
WITH THE FRONT OF THE VEHICLE FACING FORWARD.

SAFETY
Examine winches and straps to make sure they are in
good condition.
Check wheel nuts every trip.
Tires must be inflated to recommended pressure by tire
manufacturer.
Be certain the safety lock pins lock the strap winches.
Retighten the straps over the tires after the first 5 miles
of travel. Check straps every 50 miles therafter to
ensure they are tight and not rubbing or fraying.

BLEEDING THE SYSTEM
The first requirement for safe, sure hydraulic braking is the use
of quality brake fluid. Use only DOT-3 or DOT-4 brake fluid from
a sealed container.
If pressure bleeding equipment is available, follow the
manufacturerís instruction in bleeding the system.
If system must be bled manually, proceed as follows: Fill
master cylinder with fluid. Install bleeder hose on first wheel
cylinder to be bled.
Have loose end of hose submerged in brake fluid in glass
container to observe bubbling.
By loosening the bleeder screw located in the wheel cylinder
one turn, the system is open to the atmosphere through the
passage drilled in the screw. Pump actuator with long steady
strokes. The bleeding operation is completed when bubbles
no longer rise to the surface of the fluid. Be sure to close
bleeder screw securely.
Repeat bleeding operation at each wheel cylinder. During the
bleeding process, replenish the brake fluid, so the level does
not fall below the 1/2 full level in the master cylinder reservoir.
After bleeding is complete, make sure master cylinder reservoir is filled and filler cap is securely in place.

If pressure bleeding equipment is available, follow the
manufacturerís instruction in bleeding the system.
If system must be bled manually, proceed as follows: Fill
master cylinder with fluid. Install bleeder hose on first wheel
cylinder to be bled.
Have loose end of hose submerged in brake fluid in glass
container to observe bubbling.
By loosening the bleeder screw located in the wheel cylinder
one turn, the system is open to the atmosphere through the
passage drilled in the screw. Pump actuator with long steady
strokes. The bleeding operation is completed when bubbles
no longer rise to the surface of the fluid. Be sure to close
bleeder screw securely.
Repeat bleeding operation at each wheel cylinder. During the
bleeding process, replenish the brake fluid, so the level does
not fall below the 1/2 full level in the master cylinder reservoir.
After bleeding is complete, make sure master cylinder reservoir is filled and filler cap is securely in place.
After the bleeding operation has been completed, apply pressure to the system and check the whole brake system for leaks.

WIRING & FENDER
ASSEMBLY INSTRUCTIONS
NOTE: It is advantageous to wire the fender lights
prior to attaching the wheels.
1. Cut off stripped ends of the wiring harness, cut off stripped
ends of the front clearance light, and cut off the stripped
end of the white ground wire. The yellow/brown wires must
be run to the left tail light pocket. The green/brown wires
must be run to the right tail light pocket. Starting at either
fender, pull the loom downward from the center of the
fender and push the green/brown (or yellow/brown) wires
upward through the loom until it comes out by the light
pocket. Push the white ground wire through the slit in the
top of the loom in the fender trough toward the light pocket.
2. Push the brown clearance light wire through the loom on
the front of the fender until it comes out the loom in the
center of the fender, then push the brown wire through the
slit in the top of the back loom and toward the light pocket
until it comes out the loom. Mount the amber clearance
light to the front of the fender using the stainless steel
grounding strap (attached to the steel frame inside the
fender)SEE BELOW, then a 1/4" flat washer and lock nut.
Make sure the wire runs through the recess in the back of
the light so it doesn't get pinched when tightening the
mounting nut.

4. Pull the black and white wire from the pigtail through the
hole in the fender pocket outward. Splice the white wire
to the white wire coming out the loom. Splice the black
wire to the brown wire. Splice the green (or yellow) wire
to the red wire of the pigtail. Make the connections on the
outside of the fender pocket, then push the connectors
and wires back into the fender pocket. Push the grommet
into the fender with the wire loom close to the grommet.
Wrap the loom hanger tie around the wire loom and insert
the peg into fender.

5. Push the round rubber light seal into the light pocket. Be
sure the lip is secured in the light housing. Plug the pigtail
into the fender light. Push the round light into the rubber
seal until it snaps in firmly. Wire the other fender in the
same manner.
6. Mount the mud flaps to the inside back of the fender using
two 1/4" x 3/4" brown colored truss head bolts with flat
washers and lock nuts. Make sure the Kar Kaddy logo on
the flap faces the rear.
7. Attach the wheels to the main frame. Use the supplied
lug nuts (#4) and torque to 75 - 80 ft. lbs.

Inside of fender with grounding
strap attached.

WIRING OF THE TOWING VEHICLE
3. When wiring the pigtail into the tow dolly harness at the
fender pocket, the wire ends should NOT be stripped. Use
the wire connectors to make all contacts. Lay the wire in
the connector, pinch securely with a pliers, close the wire
connector.
Push the hollow looped end of the fender wireloom hanger
into the small hole under the fender pocket on the side of
the fender. Leave the holder open.
Make sure all four wires are coming out the fender wire
loom. Slide the rubber fender grommet over the wires and
up close to the wire loom. Splice the brown clearance
fender light and tow dolly brown wire together. Make sure
the connector is far enough from the loom to allow you to
push the connector into the hole in the fender pocket later.

Connect wiring to towing vehicle, keeping in mind the color
code indicated below.
1. Make certain towing vehicle lights are "OFF".
2. Connect YELLOW wire to left turn signal and stop wire in
the left rear of towing vehicle with the wire splicer (01883)
supplied.
3. Connect GREEN wire to the right turn signal and stop wire.
4. Connect BROWN wire to tail light wire.
5. VERY IMPORTANT - connect WHITE wire to frame body
of towing vehicle. This is the common ground, and a clean
metal - to - metal contact must be made.
CAUTION: Many flashers for vehicle turn signals will not
carry the additional load of Kar Kaddy turn signals. If
normal operation does not occur when connected to the
Kar Kaddy, a heavy duty replacement flasher may be
obtained through auto parts outlets.

TOE-IN ADJUSTMENT

MEASURING THE TOE-IN

Have the tongue in a "hooked-up position with the ball
coupler 18" off the ground. Jack up the axle just enough to
allow you to take the wheels off and put blocks under the axle.
Take the wheels off.
Find two 24" long bars, these could be a level, a square or
a straight piece of iron bar. Clamp one bar tight to the face of
each hub with 12" extending forward and backward of the
center of the spindle. The bars must be parallel to the platform
the car sits on. Measure across the back end of the bars and
then across the front end. The front measurement should be
1/32" to 1/16" less than the back measurement. If the unit
needs to be adjusted, this must be done by adjusting the tie rod.

1. Put a mark on each side of the locking clamp on the
tie rod.
2. Loosen the locking nuts on each end of the tie rod and then
the six bolts on the tie rod locking clamp.
3. Turn the tie rod whichever direction is needed until you
have a front measurement of 1/32" to 1/16" less than the
back measurement.
4. Hold the tie rod and tighten the locknuts on each end.
5. Measure again to make sure the toe-in measurement has
not moved.
6. Tighten the locking clamp bolts while holding clamp
between the marks you previously put on the tie rod.
7. Reassemble the rest of the Kar Kaddy unit.
