INSTRUCTIONS
WARNING – To reduce risk of injury:
1. Read and understand the entire owner’s
manual before attempting assembly or
operation.
2. Read and understand the warnings posted on
the machine and in this manual. Failure to
comply with all of these warnings may cause
serious injury.
3. Replace warning labels if they become
obscured or removed.
4. This manual pinch roll bender is designed and
intended for use by properly trained and
experienced personnel only. If you are not
familiar with the proper and safe operation of a
pinch roll bender, do not use it until proper
training and knowledge have been obtained.
5. Do not use this machine for other than its

rings, watches, other jewelry, and roll sleeves
up past the elbows. Do not wear loose clothing.

9. Keep the f loor around the machine clean and
free of scrap material, oil and grease.
10. Keep machine guards in place at all tim es when
the machine is in use. If removed for
maintenance purposes, use extreme caution
and replace the guards immediately upon
completion of maintenance.
11. Check damaged parts. Before further use of the
machine, a guard or other part that is damaged
should be carefully checked to determine that it
will operate properly and perform its intended
function. Check for alignment of moving parts,
binding of moving parts, breakage of parts,
mounting and any other conditions that may
affect its operation. A guard or other part that is
damaged should be properly repaired or
replaced
12. Use the right tool. Do not force a tool or
attachment to do a job that it was not designed

13. Remove adjusting keys and wrenches. Form a
habit of checking to see that keys and adjusting
