IMPORTANT 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 TI110SB - Brake Unit 3500 lbs.

WARNING: FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN LOSS OF TOWING VEHICLE CONTROL, SEPARATION 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 MAINTENANCE Safety is of utmost importance at all times. There are several items that must be checked each time before using and while using the Tow-It. Periodically check all bolts and nuts to ensure proper tension or torque.
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.
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 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 6.
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 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. Tiedown winch handles should be left in a down position (horizontal) with safety pins in place when towing loaded or empty.
