and/or safety and could affect the life of the equipment. There are specific applications for which
the trailer dolly was designed.
•Always check for damaged or worn out parts before using the trailer dolly. Broken parts will
affect the trailer dolly operation. Replace or repair damaged or worn parts immediately.

•Use the trailer dolly on flat and level surfaces capable of supporting the trailer dolly and its
maximum load. Pulling or pushing a load on a slanted or uneven surface can result in loss of
control.

ASSEMBLY
(See parts diagram on page 5)
1. Attach one side of brace (#4) to axle assembly (#12) using bolt (#16), flat washer (#17), ,
lock washer (#18) and nut (#19).
2. Connect brace (#4), T-Bar handle (#2) and V support (#5) together using bolts (#3), flat
washer (#6), lock washers (#7) and nuts (#8).
3. Install ball coupler (#15) onto the top of axle assembly (#12) using bolt (#13) and lock
washer (#14).
4. Assemble two wheels (#9) to axle assembly and secure them with big flat washers (#10) and
cotter pins (#11).
5. Check and tighten all fasteners as needed.
OPERATION
Design load limit is 600lbs. For the Trailer Dolly alone, not including load supported by
trailer wheels. Do not exceed the rated capacity.
Always wear approved safety goggles when working with tools and equipment.
Always keep arms, feet, and legs, etc. out from under the trailer tongue while hitching,
unhitching or moving the trailer. Children should always be kept at a safe distance.
Always make sure any loaded trailer is blocked properly while the Trailer Dolly is being
moved into place.
Make sure the trailer tongue is securely connected to the Trailer Dolly coupler ball before
attempting to unblock and move the trailer.
Take precautions to prevent uncontrolled movement of the trailer once it is connected to the
Trailer Dolly. Remember, the slope of a roadbed surface is difficult to judge, and the pull of
gravity can result in a dangerously out of control trailer.
If the Trailer Dolly is being connected to a trailer which is being stored over a lengthy period
of time, make sure both the trailer and the Trailer Dolly are blocked properly.
Keep the Trailer Dolly clean and free of road dirt. Inspect the Trailer Dolly before each use
to make sure all parts are securely in place and in working order. Periodically lubricate moving
parts.
WARNING: FAILURE TO FOLLOW THESE INSTRUCTIONS COULD
RESULT IN LOSS OF LOAD AND/OR PERSONAL INJURY OR DAMAGE TO
PROPERTY.
MAINTENANCE
•Maintain your trailer dolly. It is recommended that the general condition of any trailer dolly be
examined before it is used. Keep your trailer dolly in good repair by adopting a program of
conscientious repair and maintenance. Have necessary repairs made by qualified service
personnel.
