ASSEMBLY

TOOLS NEEDED

Two wrenches or sockets (15/16") for 5/8 bolts. (Side arms, safety chains)

Two wrenches or sockets (9/16") for 3/8 bolts. (Fenders)

Two wrenches or sockets for 1/2" bolts (Permanent ramps mounting)

Wrench (7/16) for 1/4" nuts (for lights)

Wire cutters (wire stripping and wire ties trimming)

Two 6" high wood blocks

 

1. Lay left (1) and right (2) axle assemblies on the ground, three feet apart and the central control member (3) in the middle.

2. Mount left (4) and right (5) fenders with 3/8", 1" long bolts. Use washers, lock washers and nuts inside the fenders and tighten well. Make sure the light holes (6) are positioned at the back and the splashguard is on the inside.

3. Grease side-arm holes and insert side-arms (7) in the brackets of the axle assemblies. Insert greased 5/8" bolts (8) through brackets to hold the side-arms in place.

4. Insert side-arms (7) one by one in central control member (3) brackets and drop greased 5/8" bolts in. Reasonable hammering on the bolts is acceptable and may be helpful to line them up with the bracket holes.

5. Lift and place the partially assembled dolly onto wooden blocks.

6. Insert ramps catch-bolts up into the hole in the ramp brackets and tighten with lock nut.

7. Mount tongue and the 6' towed vehicle safety chain with bolt and lock nut (11). Mount the hitch safety chains with bolt and lock nut (12).

8. Insert wire-harness through the tongue, then through the front side-arms taking care that the yellow wire goes to the left light, through axle/bracket crevices, over axle and up on the inside of the rear fender brackets.

9. Strip 1" of the wires and insert into connectors in the back of lights taking care that the left and right lights are in their respective positions. The left light has a license plate light.

Yellow - Left turn Signal and Stop
Green - Right turn signal and Stop
Brown - Tail
White - Ground -

10. Mount lights (6) to fenders with washers, lock-washers and nuts, wrapping the white ground wire around one of the light bolts. Tie harness to rear fender brackets (9). Leave enough slack (10) to allow for side-arm movement.

11. Mount wheels with lug nuts. Remove the support blocks and lower dolly to the ground. Do not forget to check and retighten lug nuts after several miles of towing.

12. Under side-arms (7), tighten all eight lock nuts to the eight side-arm bolts (8) sufficiently until snug. Do not over-tighten. The side-arms (7) must be snug but able to move freely.

13 If you will be using the trailer option, screw in tilt bolt and slightly scour end of thread to prevent it from easily unscrewing and falling out. You may tilt the trailer using a ratchet wrench.

RAMP OPTIONS

Removable ramps give you maximum length and flexibility when it comes to towing low front-end vehicles. If the vehicle you will tow has 8 inches or more front end ground clearance, for convenience, you could mount the ramps permanently. Each ramp is bolted-on with two 1/2" bolts down through the wheel pad and ramp and tightened with two washers and lock nuts. Make sure the cutout in the ramp is in position to allow for the insertion of the strap hook.

HITCHING

1. Make sure the hitch ball is all the way in and coupler is tightened.

2. Cross safety chains under the tongue and attach to towing vehicle.

3. Connect lights.

 

LOADING

DO NOT ATTEMPT TO LOAD A VEHICLE IF THE DOLLY HAS NOT BEEN PROPERLY HITCHED!

IT IS USEFULL TO HAVE ANOTHER PERSON WATCH WHILE A VEHICLE IS BEING LOADED, TO ENSURE THAT AS YOU DRIVE ONTO DOLLY, THE WHEELS ARE LINED UP AND THE VEHICLE BUMPERS HAVE ENOUGH CLEARANCE. FAILURE TO LINE UP THE WHEELLS COULD RESULT IN TIRE DAMAGE.

LOADING WITH PERMANENT RAMPS

1. Drive the vehicle you are about to tow to the rear of the tow dolly and stop about a foot from the ramp edges. Inspect if vehicle bumper will clear the ramps.
If the vehicle has a long front-end overhang or low bumpers with less than 8" ground clearance, we strongly recommend that you use the removable ramps option.

2. Pull tow dolly apart to match the width of the vehicle you are about to tow. You may use the fenders to lift and pull.
3. Remove tilt pin. The dolly will not tilt.
4. Slowly drive up to the ramps. The wheels will push the ramps down to the ground and the dolly will tilt. If the tires of your vehicle are very wide, make sure that they will fit in the wheel pads of the tow dolly.
5. Drive up the ramps until dolly snaps in place and is no longer tilting.
6. Set parking brake and make sure vehicle does not roll back.
7. Insert tilt pin and secure with clip.

LOADING WITH REMOVABLE RAMPS

1. Drive the vehicle you are about to tow to the rear of the tow dolly and stop about 3 feet from dolly.
2. Pull tow dolly apart to match the width of the vehicle you are about to tow. You may use the fenders to lift and pull.
If the vehicle has a long front-end overhang or low bumpers, you may need ramp extenders. You could use 4-5 foot long 2x10 boards as extenders to give you 2-3 inches of extra lift.

3. Place the ramp end with the cross plate at the edge of the ramp bracket and make sure the ramp catch bolt is in place to prevent the ramp from slipping out. Make sure the other ramp end is on level ground and the ramp lays flat on the ramp bracket. The ramp should not wobble.
4. DO NOT Remove tilt pin. Slowly drive up to the ramps and double check that the wheels line up. If the tires of your vehicle are very wide, make sure that they will fit in the wheel pads of the tow dolly.
5. Drive up the ramps until the vehicle wheels touch the wheel stops at the front.
6. Set parking brake and make sure vehicle does not roll back.
 

TIE DOWN

1. Make sure the parking brake is set and the vehicle can not roll back.
2. If the ramps are removable, you may pick them up and store them in the trunk of the vehicle or, you may push them all the way in under the wheel pads.
3. Insert the strap hooks in and away from the wheel. If you stored the removable ramps under the wheel pads, the hooks will keep the ramps in place. The ratchet should be at the front of the wheel.
4. Tighten the straps as much as you can. It is not humanly possible to over-tighten.

 

TOWING

LOADED

1. Make sure the tilt pin is in place and secured with clip and the wheels have been tied down.
2. Release the parking brake.
3. Unlock the steering wheel. Leave the key in a position to keep the steering wheel unlocked, but do not activate the ignition.
4. Place a rear wheel transmission in NEUTRAL. Towing rear wheel drive vehicles for a significant distance may cause transmission damage due to the fact that transmission lubricants can not get to the bearings. Short distances may be OK depending on the vehicle, but you should always consult with your vehicle manufacturer.
5. After towing for several blocks, stop and retighten wheel straps.

The towing vehicle should be at least 750 lbs. heavier than the towed vehicle.

Hard braking while towing with a sport utility or other high center of gravity vehicle with a high ball may cause the towed vehicle/dolly combination to push up the rear end of your towing vehicle and result in loss of control.

If the rear end of your towing vehicle is light, hard braking into a turn may result in loss of control.

UNLOADED

1. Make sure the tilt pin is in place and secured with clip.
2. Fold tow dolly.
3. Pull the 6' safety chain back and up at the end of the central control member. Wrap around both side-arms to the right, then up and around both side-arms to the left. Connect the chain to itself as tight as possible with the rapid-link. This will keep the tow dolly from spreading while towing.
4. If the ramps are removable, you may store them:
a) in the trunk of your vehicle along with the wheel straps or
b) under the wheel pads. To store them under the wheel pads, push the ramps all the way in. Hook the end of the ramps with the strap hooks and
tighten ratchets.

UNLOADING

UNLOADING WITH PERMANENT RAMPS

1. The wheels of the vehicle should be all the way forward and touching the wheel stop at the front.
2. Set the parking brake.
3. Place transmission in gear or PARK.

Make sure the vehicle does not roll back on it's own when you remove the tilt pin and straps.

4. Remove tie-down straps. To release straps, pull the ratchet lever and straighten ratchet. If the bumpers get in the way and there isn't enough space to straighten the ratchet up, you may press the plate above the spring down, while pulling the release lever to loosen the straps.
5. Remove tilt pin.
6. Remove the safety chain from the towed vehicle.
7. Backup vehicle.

UNLOADING WITH REMOVABLE RAMPS

1. Set parking brake.
2. Place transmission in gear or PARK. Make sure the vehicle does not roll back on it's own.
3. Remove tie-down straps. To release straps, pull the ratchet lever and straighten ratchet. If the bumpers get in the way and there isn't enough space to straighten the ratchet up, you may press the plate above the spring down, while pulling the release lever to loosen the straps.
4. If the ramps were stored under the wheel pad, pull out and drop to the ground. If the ramps were stored in the trunk, place them on the edge of the ramp brackets and make sure the catch bolts are in place to keep the ramps from slipping out
5. Backup vehicle.

 

OPTIONAL UTILITY TRAILER FRAME AND BED

BED ASSEMBLY

1. Bolt on both L brackets to front rail and mount to tow dolly's central control member. There are 2 possible positions. The front, tilt pin position will give you more tongue weight and more ground clearance at the tail of the trailer. The rear, bolt position will give you just 50 lbs. of tongue weight with the box installed and a more balanced load.

2. Bolt on the side rails to front rail.

3. Bolt on rear support rail under the side rails.

4. Bolt on the two attachment brackets under the side rails and to the wheel pad wall using bolts and lock nuts.

5. Measure and drill 1/4" holes along the plywood edge, taking care to leave 3/4" gap between the plywood and the rails where the box walls will slide in.

 

REMOVAL OR REATACHMENT

To remove trailer frame, remove the two bolts holding the side rails to the wheel pads. Remove the front 3/4" bolt or tilt pin and lift bed off tow dolly. To install, remove the tongue tilt pin or bolt. Lower bed onto tow dolly and insert and secure tilt pin or bolt. Bolt-on side rail brackets to wheel pads.

 

4' HIGH TRAILER BOX

Materials required: 3 sheets of 1/2" plywood, five 8' 2x4 studs minimum, more if you need additional wall strength.

 

INSTALLING BOX

1. First install front panel and bolt on with two bolts to front rail.

 

2. Install side panels and secure to front panel hinges by dropping 2 bolts in the hinges and bolt to the side rails at the rear corners.

3. To install gate, drop 4 long bolts in the hinges. Be aware that driving over speed bumps or rough road may cause a bolt to jump out of a hinge. You could use lock nuts to prevent bolts from jumping out.
