relating to all Lewis Manufacturing Company products before
use. Make a complete inspection of swivels before each use.
Do not alter or modify units. Make sure that the end pens
make up properly and Allen screw is in place. Rotate swivel
by hand to determine proper operation of bearings. Please
order carefully. Lubricate all grease able swivels before
and after each use. Do not exceed published working load on
any Lewis ball bearing swivel. |
