PSI), damaged tail lights, damaged side running lights, loose bolts and nuts, structural cracks and bends, and any other condition that may affect its safe operation. Do not use the Trailer even if minor damage appears.

3. Never allow adults, children, or pets to ride in or play on the T railer.

4. IMPORTANT: Whenever a Hub (26) on a new Trailer requires assembly (or if a Hub is disassembled for maintenance) the following procedures MUST be followed:

A. Using a suitable solvent, thoroughly clean the Hub Set (26), Outer Bearings

(27), Castle Nut (28), Dust Cap (29), and the rest of the parts of the Hub Assembly of all grease, dirt, metal shavings, and all other foreign objects. These

parts must be cleaned, even if they are new or appear to be clean. (See Figure B.)

B. Allow all parts to dry completely.
