We have discovered 1992 and newer model cars that are too wide in the body area to properly fit on a TI110 - 8' wide tow dolly
even though the front tire measurement is less than 70".
The 1992 and newer Oldsmobile 88 and 98 are in this category, there may be others. In addition to the standard measurement,
always follow weight limitations when using a Demco TOW-IT Tow Dolly.
TI100 - Standard Unit
3350 lbs. - Total Towed Vehicle Weight
WARNING: Exceeding weight limitations or not using a towing vehicle larger and at least 1,000 lbs. heavier
than the tow dolly and the towed vehicle combined can result in loss of towing vehicle control, separation of the tow
dolly from the towing vehicle, or separation of the towed vehicle from the tow dolly, causing severe personal injury,
death, or property damage.
CAUTION: All vehicles to be towed on Demco Tow Dollies must be towed with the front axle on the dolly.

SAFETY
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN LOSS OF TOWING
MAINTENANCE
Safety is of utmost importance at all times. There are
several items that must be checked each time
using and
Make sure all bolts are properly tightened and those
requiring a set torque are up to specifications:
Lug Nuts - 75 to 80 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 Tow-It. 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 TI110 tires must be inflated to the recommended 35
PSI.
The TI110SB 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
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.
All vehicles mounted on the Tow-It must be mounted
with the front of the vehicle facing forward.
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.
while using the Tow-It.
before
securely at
Periodically check all bolts and nuts to ensure proper
tension or torque.
An occasional drop of oil may be required on the moving
parts of the tie down winches.
Grease the center pivot pin grease zerk every 1500
miles.
Grease the main frame platform skids every 1500 miles.
These grease zerks are readily accessible from under
the front tire stop main platform.
Grease the Sure Lube
TM
Hubs every 3,000 miles.
Use High Quality Bearing
Grease with Hand Operated
Grease Gun.
IMPORTANT LOADING INSTRUCTION
Check your wheel tie-down straps.
Your Tow-It 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 of your car and the tire
size.
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 of your
car and tire size.

TESTING LIGHTS BEFORE USE
1. Check that the WHITE (ground) wire of the wiring harness
is connected to the Tow-It 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 Tow-It 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 and GREEN
wires have been reversed. Check the plug connection
under the tongue of the Tow-It 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.
LOADING INSTRUCTIONS
Refer to load limits on inside of front cover.
Step 3. To allow the wheel platform to tilt back for loading:
1) Swing the bottom of the locking latch (C) toward the hitch
far enough to allow locking pin handle to be lifted.
Step 1. Secure ball coupler to 2" (3,500 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.Ensure that towed vehicle parking brake is fully
engaged, then release the tie-down straps. NOTE:Tie down
straps must be "quick -released" by grasping ratchet pawl and
ratchet handle simultaneously and pushing down sharply. This
process will permit easy removal of strap from winch.Remove
tie-down strap hook from its storage position at the rear of the
ramp. Lay the straps on the ground in front of the winches.
2) Pull locking pin toward the hitch as far as it will go. The wheel
platform will tilt back to allow loading.
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:
TI110-70" max. (outside to outside),
TI110SB42" min. (inside to inside),
70" max. (body width)
Page 6
Page 7
Step 5. 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 7. 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 TOW-IT.
Step 8. Be sure tie-down winch is centered with the tire before
tightening straps.
Step 6. Drive vehicle onto 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.
IMPORTANT: Lock the platform in position by pushing
locking pin toward platform. Push the handle down as far
as possible so locking latch holds it in a locked down
position.
Step 9.While tightening straps, pull cross strap forward to
ensure even tightening. 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.
(continue with Step 10 on following page)
Page 7
Page 8
Step 10. Make sure the tie-down strap is the correct size for
the auto tire. The picture above shows a correct fitting strap.
See page 1 of this instruction for proper fit and exchange
instructions.
Step 11. Hook the towed vehicle safety chains to frame of
vehicle directly above the area where the chains are mounted
on the TOW-IT. Leave some slack in the chains to allow
suspension movement of the towed vehicle. Review the
safety points on page 1 before moving vehicles.
Step 13. To pull the TOW-IT empty, make sure tie-down
straps are tightened in the storage position, and towed
vehicle safety chains are wrapped up and hooked. Tie-
down winch handles should be left in a down position (horizontal) with safety pins in place when towing loaded or empty. DO
NOT ATTEMPT TO PULL TOW-IT 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
Tow-It or exceeding the width limit may result in damage to
both car and Tow-It.
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 TOW-IT MUST BE WITH THE
FRONT OF THE VEHICLE FACING FORWARD.
Step 12. 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 tie-down straps.
NOTE: Tie down straps must be "quick -released" by grasping
ratchet pawl and ratchet handle 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.
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 thereafter to
ensure they are tight and not rubbing or fraying.

6. When assembling the tie-down strap to the tow dolly winch,
make sure the tie-down strap does not contain any twists and
the overlaps are to the inside. Weave the front of the tie-down
strap through the openings in the buckle. The buckle should
be approximately 8" from the end of the strap. Thread the strap
end through the winch slot. Bring the strap up and thread it back
through the buckle again. The buckle should be approximately 1-1/2" - 2" from the winch.
(Refer to drawing on page 9 for following steps)
7. Attach Hub and Spindle Assembly (#19) using 7/16" x 1-1/4"Fine Thread Bolts (#20) and hex nuts.
8. Bolt the fenders (#21) on using 3/8" x 1-1/2" gr. 5 bolts (#22),
back-up plates (#23) and locknuts (#24) in each fender. Mount
the fender with the light pocket to the rear. Attach the whiteground wire (#25) (the end with the eye loop on it) under the
center top bolt head.
3. Mount the tongue to the front of the tow dolly using one 5/8"
x 4-1/2" grade 5 bolt (#8) and locknut(#9) (torque to 50 ft. lbs.).
Do not torque over 50 ft. lbs. or the bed will not tilt. Make sure
the tongue latch is in the latched position to the tilt bed.
4. Secure the coupler (#10) and lift handle (#11) to the front end
of the tongue with two 1/2" x 4-1/2" gr.5 bolts (#12) and
locknuts (#13) . The white ground wire (#14) is attached under
the head of the second bolt attaching the coupler. (It is veryimportant that a good ground is made). Torque the locknuts
to 75 - 80 ft. lbs. Tap a rubber grip (#15) onto the handle with
a rubber hammer or a wooden mallet.
5. Remove the 7/16" x 1-1/4" bolt (#16), flatwasher, and locknut
from the outer front panel of each wheel platform tire stop.
Slide the tie-down winch (#17) into the channel at the front of
the wheel platforms as shown. Note that #17 is the left winch.
The ratchet handles are to the outside of each winch and
ratchet springs are to the top. Attach two 36" towed vehicle
safety chains (#18). Secure one chain to each wheel platform
tire stop with the 7/16" x 1-1/4" bolt (#16) , flatwasher and
locknut.
NOTE:It i s advantageous to wire the fender lights prior to
attaching the wheels.
9. Cut off stripped ends of the wiring harness, cut off 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. Start at either fender, pull the loom
at the center of the fender downward and push the green/
brown (or yellow/brown) wires upward through the loom until
it comes out the loom by the light pocket. Push the white ground
wire through the slit in the top of the loom in the fender trough
and push the wire toward the light pocket.
10. Make sure all three wires are coming out the fender wire loom.
Slide the rubber fender grommet over the wires and up close
to the wire loom.
Push the hollow looped end of the loom hanger into the small
hole under the fender pocket in the side of the fender. Leave
the holder open.

the wire in the connector, pinch securely with a pliers, closing
the wire connector. Splice the white wire of the pigtail to the
white ground wire from the fender. Splice the black wire to the
brown wire. Splice the green (or yellow) wire to the red wire
of the pigtail. The connections are made on the outside of the
fender pocket and pushed into the fender pocket through the
pocket hole. Pull the wires back into the fender pocket and
push the strain relief into the fender with the wire loom close
to the clip. Wrap the loom hanger tie around the wire loom and
insert the peg into the fender.
11. Push the round rubber light seal (#26) 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 (#27) into the rubber
seal until it snaps in firmly. Wire the other fender in the same

14. Attach the two 24" transport safety chains (#35) to the two
holes in the angle located under the tongue using two 7/16"
x 1-1/4" grade 5 bolts (#36), flatwashers (#37), and locknuts
(#38). Torque bolts to 50 ft. lbs.
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 X) supplied.
3. Connect GREEN wire to the right turn signal and
stop wire.
4. Connect BROWN wire to tail light wire.
13. Lay the bracing struts (#29) out along the tow dolly tongue
with the back end (the end with the larger hole in it) of the
bracing strut toward the mainframe. Loosely bolt the back of
each bracing strut to the trailer frame as shown using 1/2" x
1-1/2" grade 5 bolt (#30), flatwasher (#31), pivot bushing
(#32) and locknut (#33). Hold up the front end (the end with
the smaller hole) of each bracing strut to the tongue, align
holes and secure with a two 5/8" x 1-1/4" epoxied bolt (#34).
Torque the 1/2" x 1-1/2" bolt with the pivot bushing to 75 ft. lbs.
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 TOW-IT turn
signals. If normal operation does not occur when
connected to the TOW-IT, a heavy duty replacement flasher may be obtained through auto parts
outlets.

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.
After the bleeding operation has been completed, apply pressure to the system and check the whole brake system for leaks.
