TOW DOLLY USER GUIDE

WARNING

Read the following information completely before hooking up, loading, using unloading or

unhooking this Tow Dolly.

FAILURE TO FOLLOW THESE SAFETY INSTRUCTIONS

MAY LEAD TO DAMAGE TO PROPERTY, SEVERE PERSONAL INJURY, AND/OR DEATH.

• Read towing instructions in towed vehicle’s owner’s manual.

• Read towing instructions in towing vehicle’s owner’s manual. Be certain that your towing vehicle has the capacity to tow a tow dolly and towed vehicle combination. IF YOU HAVE ANY QUESTIONS ABOUT THIS, DO NOT TOW. CONSULT YOUR DEALER OR CALL DEMCO.

• Use a 2", 5000 lb. (or greater) capacity ball for a tow dolly without surge brakes and a 2", 6000 lb. (or greater) capacity ball for a tow dolly with surge brakes.

• Make sure towing vehicle’s parking brake is fully engaged before starting hookup, loading, unloading, or unhooking of tow dolly.

• Do not load towed vehicle onto tow dolly until tow dolly is completely and properly hooked up to towing vehicle and setting on a level surface.

• Tail lights and stop lights must be hooked up and operating properly at all times.

• Do not load a towed vehicle that exceeds weight or size limits of tow dolly.

• Always have someone safely guide you when driving towed vehicle onto tow dolly.

• Be sure tires of your towed vehicle and tow dolly are in good condition and inflated to proper pressures. Tire pressure may increase during travel—do not bleed off extra pressure.

• Do not back up your towing vehicle when a tow dolly is attached. A tow dolly swivels both at the coupler and at car platform. If you must back up, unload towed vehicle first, disconnect tow dolly and move vehicle and tow dolly separately. Park where you can pull ahead when leaving.

• Do not exceed 55 miles per hour, or any lower posted speed limit.

• Avoid sharp turns or swerves.

• Braking distance increases when using a tow dolly. Use caution and always allow sufficient distance for braking.

• Do not transport passengers or cargo in vehicle being towed.

• Do not unhook tow dolly from towing vehicle until towed vehicle is completely unloaded from tow dolly.

Page 4

• Allow one tow-vehicle/tow dolly/vehicle-in-tow length for each 10 m.p.h. behind another vehicle.

• ALWAYS check the hitch, tow dolly and vehicle-in-tow at each stop to insure that coupling, chains and tie down equipment remain tight and properly attached. Use tow dolly checklist as an aid.

• NEVER tow without properly installed tire straps and security chains properly attached to frame or other structural member of vehicle-in-tow.

• ALWAYS slow down—40 miles per hour or less—for curves, wet or rough roads, and downgrades. On downgrades, shift into a lower gear and allow engine to help hold speed down.

• ALWAYS be rested. NEVER drive when fatigued.

• AVOID driving at night. Night drivers have three times the fatality rate of day drivers.

• NEVER continue to operate an unstable (swaying or whipping) combination. If this occurs, slowly pull over, reducing speed through your engine rather than braking. When stopped in an off the road location check hitch, tire straps, and chains.

• NEVER pass on hills or curves. Beware of cross winds and wind gusts from passing vehicles.

• NEVER transport passengers or cargo in towed vehicle.

• ALWAYS load vehicle-in-tow facing forward. NEVER back onto tow dolly. For maximum stability steering axle must be on tow dolly.

• ALWAYS disconnect drive shaft of a rear wheel drive/front engine vehicle-in-tow at differential to avoid transmission damage. Secure disconnected parts.

• ALWAYS ensure vehicle-in-tow parking brake is disengaged before towing.

• ALWAYS keep children, pets, and bystanders clear of area while loading and unloading.

THE MOST IMPORTANT PART - IS YOU

Will you read and follow these instructions on how to safely operate this Dethmers Tow

Dolly?

If your answer is YES, we thank you for your attitude and believe your towing experience

will be a safe and pleasant one.

Page 5

When On the Road:

• Reduce Speed

• Think Ahead

• Allow for extra length when turning

• Anticipate Stops/Brake Early

• Stop Often for Rest

• Use Safety Checklist at Each Stop

TOWING VEHICLE SIZE AND TOWING CAPACITY

Towing vehicle must weigh at least 750 lbs. more than weight of vehicle-in-tow. Example: A

2,750 lb. car may tow no more than a 2,000 lb. car.

Suspension

Your tow vehicle’s rear springs must be of sufficient strength to support the added loaded tow dolly tongue weight while maintaining tow vehicle in approximately a level position. If rear springs, shock absorbers, or struts, are weak or broken, they must be replaced. In some cases, it may be necessary to add helper springs or air shocks to help support weight properly. Poor wheel alignment, loose steering or worn suspension components can also adversely affect vehicle handling and stability.

Sport Utility Vehicles

Exercise caution when towing with a sports utility (e.g., Jeep or Bronco) type vehicle. Some of these vehicles have a higher than normal center of gravity, and a short wheelbase. This gives them different handling characteristics than the average car or truck.

Tires

You must increase pressure in rear tires of tow vehicle to accommodate extra weight of tow dolly. When cold, inflate rear tires to approximately 6 pounds above their normal operating pressure, but DO NOT exceed pressure limit molded into tire sidewall. Normal pressure should be maintained in tow vehicle’s front tires.

Tow dolly tires should be inflated to pressure recommended on operational decal on fender (45 or 50 psi). These are COLD pressures, and will increase when tires are hot from running. DO NOT bleed off this pressure increase. Incorrect tire pressure can adversely affect vehicle handling and gas mileage.

Mirrors

State laws require vehicles towing a tow dolly to be equipped with mirrors on both sides. Inadequate side mirrors create a hazard by limiting rearward vision. If your vehicle is not already so equipped, you should put right and left hand full view, detachable mirrors on. Ask dealer if it has any available for rent if you do not want to purchase them.

Page 6

Engine and Transmission Cooling

Towing a loaded tow dolly can be quite demanding on engine and transmission cooling systems of tow vehicle, especially if towing Iong distance or in hilly terrain. Be sure your cooling system is in top shape, and adequate for towing anticipated load. Engine oil should be fresh and of maximum viscosity recommended for your particular engine. Engine cooling may be enhanced by flushing system and installing fresh coolant. Automatic transmissions may need an external oil cooler installed for unusually difficult or extended towing.

Engine and transmission heat increase as vehicle speed increases. To maintain proper cooling, do not exceed 55 m.p.h. regardless of engine size or load.

Hitch

Be certain that hitch and hitch ball are securely attached and that hitch ball is 2" in diameter. A minimum rating of class II (3500 lbs) is required for both hitch and hitch ball.

Some sports utility vehicles are equipped with a bumper type hitch from the factory. DO NOT USE THESE HITCHES, since bumper may not have sufficient structural capacity to handle the load. Equip your vehicle with a hitch attached to the undercarriage of your vehicle.

Lights

Lights are required on tow dollies in every state. If your vehicle is not already equipped for tow dolly light hook-up, it will be necessary to install connections now. Your dealer will let you know exactly what is needed for your particular vehicle.

Tow Vehicle Loading

A loaded tow dolly tongue weight (approximately 200 lbs.) contributes to total cargo weight of tow vehicle. Tow vehicle manufacturer’s recommended maximum passenger/cargo load must not be exceeded.

VEHICLE-IN-TOW

Limitations/Cautions

1. Vehicle-in-tow must Not be wider than 76 inches at front doors to prevent damage to doors from contact with tow dolly fenders on turns.

2. Vehicle-in-tow must Weigh no more than 4,400 lbs. Exceeding these limits may cause damage to tow dolly or vehicles. Vehicle-in-tow tire tread must fit on ramps without overhanging sides. Track width (distance from

left front tire center to right front tire center) must be between 49 and 59 inches. Low hanging spoilers and air dams may be damaged by contact with tow dolly ramps when loading

and unloading. Be sure there is adequate clearance for these. If not, they must be removed before loading.

Page 7

Vehicle-in-Tow Facing Forward

Vehicle-in-tow must always be facing forward (front wheels on tow dolly).

Transmission Damage to Towed Vehicles

When towing a rear axle driven front engine vehicle, the drive shaft must be disconnected to prevent transmission damage. Simply placing transmission in neutral is not sufficient and will not prevent damage due to a lack of internal lubrication. You must disconnect drive shaft at rear axle and tie or wire it up. The universal joint bearing caps must be taped on to prevent loss of bearings. If you choose to remove drive shaft entirely, it may be necessary to cap transmission tail shaft to prevent fluid loss and possible future damage. Consult your vehicle owner’s manual.

Front wheel drive vehicles need not have drive shafts disconnected because the drive wheels are loaded on tow dolly.

Towing damages many rear engine vehicle with transaxles. Consult owner’s manual for tow suitability.

Passengers And Cargo Prohibited in the Vehicle-in-Tow

Never transport any passengers or cargo in towed vehicle. In addition to being illegal in most states, carrying passengers in a towed vehicle exposes those passengers to risk of exhaust gas asphyxiation.

Lighting Requirements

Even though tow dollies have operating lights, law requires that a vehicle-in-tow be equipped with functioning stop, turn and running lights. Detachable vehicle-in-tow towing lights can be purchased at many rental locations. They can also be purchased at auto supply shops. Follow instructions carefully when installing.

TOW DOLLY HOOK UP

Double Check

After rental company has “hooked up” your tow dolly, it is wise for you to double-check connections both before and during trip.

ALWAYS FOLLOW HOOK-UP, LOADING, AND UNLOADING INSTRUCTIONS ON FENDER DECALS OF TOW DOLLY. IF YOUR TOW DOLLY DOES NOT HAVE INSTRUCTIONS OR IF THEY ARE ILLEGIBLE, ASK COMPANY FOR A LEGIBLE COPY.

Page 8

TOWING

55 Miles Per Hour

All vehicle combinations have a speed beyond which adequate emergency control cannot be assured. Maximum recommended speed for all tow dolly combinations is 55 m.p.h. under good road conditions. As road conditions deteriorate you must reduce the maximum recommended speed.

Posted speed limit is usually the same for trucks and car-trailer combinations. Observe this limit even if it is less than 55 m.p.h.

Please do not be lulled into a false sense of security because your tow dolly tows easily at higher speeds. A road hazard that would be avoidable at 55 m.p.h. can become unavoidable at 65 m.p.h.

If you drop any wheel(s) off the pavement, don’t attempt any sharp steering corrections.

Remain off the pavement, decrease your speed until you have regained control, then drive slowly back onto pavement.

Never Operate An Unstable Combination

Instability (swaying or whipping) of a tow vehicle/ tow dolly combination at low speeds usually increases at higher speeds. If combination begins to whip or sway, steer straight ahead, take your foot OFF the throttle, but do not brake until combination has stabilized. Stop in an off the road location and check tow vehicle and tow dolly as soon as possible.

• Review all instructions and be sure you have complied.

• Check that vehicle on tow dolly is loaded with front wheels on tow dolly. Reload if necessary.

• Check that all chains and tie down equipment remain tight and properly attached.

• Check for proper tire inflation all around combination.

• Make sure trunk or bed of towing and towed vehicles are not loaded with cargo.

• Check wheel bearings and lug nuts on both tow vehicle and tow dolly to be sure a wheel has

not become loose.

• Check tow vehicle’s wheel alignment.

• Finally, be sure you are not exceeding maximum recommended speed (55 MPH).

If you have followed preceding instructions, any instability should be corrected. If situation persists, stop and call for professional assistance from a tow truck operator.

BREAKDOWNS

Get Off The Road

Immediately park tow vehicle-tow dolly combination in a safe place completely off the highway. Get all occupants out of vehicle and away from roadway.

If you must continue on the highway to reach a safe place off the road, turn on emergency flashers and proceed with caution.

Do not hesitate to proceed on a flat tire if necessary to reach a safe place completely off the highway. Proceed slowly, for road friction could ignite a flat tire and cause a fire.

Rough Roads

To prevent damage to tow vehicle or tow dolly, reduce speed when towing tow dolly over rough roads.

Turning

Avoid U-turns. Avoid turning too sharply. Turning too sharply may cause side of vehicle-intow to come in contact with rear of dolly fender and cause damage to both vehicles.

“Pro” Driving Tips

Accidents occur more frequently at night with a tired driver exceeding recommended speed on a downgrade, wet road, or curve. Don’t attempt to drive “straight through.” Be rested. Slow down for down-grades, wet roads or curves. Night drivers have three times the fatality rate of day drivers. Avoid driving at night.

ACCIDENTS

Move all vehicles completely off the road. Get everyone out of the vehicle and off the road. Call police.

Dethmers Manufacturing Company wants you

to have a safe towing experience.

Read these instructions carefully,

read fender decals on tow dolly,

and follow all instructions.

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 Kar Kaddy.

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 - 120 ft./lbs. Check Lug Nut tension after the first 5 miles and periodically

thereafter. 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.

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 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.

before using and while using the

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.

MAINTENANCE

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

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

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

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, 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.

call us, we will provide at NO Charge

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 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.

securely at the rear of

Loading Angle Clearance Guide

NOTE: User’s responsibility for checking clearance

IMPORTANT:

Using this guideline will reduce the chance of the towed vehicles air dam, or bottom of facia from interfering with tow dolly platform and or tire stop. “X” must be less than 3-1/2 x “Y”.

Example: If Y measures 6”

3-1/2 x 6 = 21 X must measure less than 21”

Page 14

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, exchange basis, the proper size strap. You must new unused straps and provide us with the Make and Model car and tire size.

LOADING INSTRUCTIONS

Step 1. Secure ball coupler to 2" (6,000 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 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.

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).

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.

IMPORTANT: Tire tread width or body width of towed vehicle

must not exceed:

76" max. (outside to outside), 42" min. (inside to inside), 78" max. (body width).

Page 15

Step 5. Grasp bed release handle on tongue and pull toward coupler. This releases the tilt bed to permit loading.

Step 6. With someone safely guiding you, slowly drive vehicle onto platform FRONT FORWARD. (Any vehicle mounted 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 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 9. Be sure tie-down winch is centered with the tire before tightening straps.

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 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 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.

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

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.

Step 13. TO UNLOAD towed vehicle. Make sure that plat-

form 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 tiedown 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).

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 manufacturer’s 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.

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.

WIRING OF THE TOWING VEHICLE

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.

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.

12"

TOE-IN ADJUSTMENT

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.
