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 pneumatic sheet metal notcher is designed
and intended for use by properly trained and

familiar with the proper and safe operation of a
sheet metal notcher, do not use it until proper
training and knowledge have been obtained.

5. Do not use this sheet metal notcher for other
than its intended use. If used for other
purposes, JET disclaims any real or implied
warranty and holds itself harmless from any
injury that may result from that use.

6. Always wear ANSI Z87.1 approved safety

exceeds safe levels.

8. Before operating the machine, remove tie,
rings, watches, other jewelry, and roll sleeves
up past the elbows. Do not wear loose clothing.

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
