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
experienced personnel only. If you are not
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
glasses or face shield while using this machine.
(Everyday eyeglasses only have impact
resistant lenses; they are not safety glasses.)
7. Wear ear protectors (plugs or muffs) if noise
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.
Confine long hair.
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. Make all machine adjustments or maintenance
with machine unplugged from power source.
13. Use the right tool. Do not force a tool or
attachment to do a job that it was not designed
to do.
14. Make certain the switch is in the OFF position
before connecting the machine to the air or
power supply.
15. Remove adjusting keys and wrenches. Form a
habit of checking to see that keys and adjusting
wrenches are removed from the machine
before turning it on.
16. Give your work undivided attention. Looking
around, carrying on a conversation and "horseplay" are careless acts that can result in serious
injury.
17. Keep visitors a safe distance from the work
area. Keep children away.
18. Make your workshop child proof with padlocks,
master switches or by removing starter keys.
19. Do not overreach. Failure to maintain proper
working position can cause you to fall into the
machine or allow clothing to get caught, pulling
you into the machine.
20. Keep the floor around the machine clean and
free of scrap material, oil and grease.
21. Use recommended accessories; improper
accessories may be hazardous.

5.0 Setup and assembly
Open shipping container and check for shipping
damage. Report any damage immediately to your
distributor and shipping agent. Do not discard any
shipping material until machine is assembled and
running properly.
Compare the contents of your container with the
following parts list to make sure all parts are intact.
Missing parts, if any, should be reported to your
distributor. Read the instruction manual thoroughly
for assembly, maintenance and safety instructions.
screws or other appropriate fasteners
through two holes in base (inside cabinet).
4. Exposed metal surfaces have been given a
protective coating. Remove this with a soft cloth
and a cleaner-degreaser. Do not use gasoline,
paint thinner, acetone, etc., as these may
damage painted surfaces. Do not use an
abrasive pad, as it may scratch polished
surfaces.
5.3 Air settings and lubrication
NOTE: Lubricator bowl (H, Figure 5-2) is not
supplied with oil. Fill bowl to indicator line before
operating notcher.
1. Make sure air c ompressor supplies clean, dry
air at correct CFM for the machine. Blow out air
supply line to remove any dirt or moisture, and
connect hose to fitting (A, Figure 5-2) using a
quick-connect coupling. Hose should be just
long enough to serve the working area.
Excessive hose length may cause pressure
drop.
Excess air pressure and/or
unclean air will reduce the machine’s
service life and may create a hazardous
situation.
5.2 Location and cleanup
1. Remove any fasteners holding machine to
pallet.
2. Use forklift or hoist with straps to carefully move
machine off pallet and into position. Lifting
equipment must be properly rated for weight
of machine. Position forks or straps below
table as shown in Figure 5-1.
Figure 5-1: lifting the machine
3. Position notcher so there is enough room on all
sides for general maintenance and feeding of
materials. Level the machine; use shims if
needed.
2. The sliding valve (B) is used to turn air flow on
and off. ON: slide toward regulator, OFF: slide
away from regulator.
3. Air pressure has been pre-set for 115 psi (8

pull up on pressure regulator (C) and rotate.
Check pressure gauge (D) to confirm setting,
then push regulator down to lock setting. Do not exceed 140 psi air pressure.
Clockwise decreases oil flow, counterclockwise
increases. A setting of 1 drop per every 5 cycles
is sufficient for regular operation.

6.0 Operation
6.1 Controls
Press foot pedal to activate machine. Cutting head
will descend and remain in down position until foot
pedal is released.
An Emergency Stop switch (E-stop) is located atop
the foot pedal post; push for immediate shut-down
of machine. To restart, rotate E-stop clockwise until
it disengages.
6.2 General operating procedure
1. Use scales (A, Figure 6-1) to help determine
notching size.
2. Place angle indicator (B) against fence to help
set angle for workpiece.
3. Position fences (C) to secure workpiece in
place, and tighten handles.
4. Press foot pedal to operate. Cut pieces will drop
into tray inside cabinet.
Falling sheet metal piece s
can cause foot injury. Use appropriate
footwear when operating this machine.
2. Turn off air with sliding valve (see B, Figure 5-
2) and bleed residual air from system (see G,
Figure 5-2).
3. Release foot pedal.
4. DISCONNECT air supply from machine.
5. Remove screws (D, Figure 8-1) and head guard
(E).
6. Use feeler gauge to measure gap between
upper and lower blades (Figure 8-2).
7. Make adjustments using hex nuts beneath
table. Turn (F) to raise or lower blade, turn ( G)
to move in and out. Feeler gauge should be
snug but can still be smoothly removed.
8. Make sure blades are flush against each other
at the corners. See Figure 8-3.
9. Reinstall head guard and tighten screws.
Figure 6-1
7.0 Adjustments
Disconnect machine from air
supply before working with or near the blades. If
head guard is removed for adjustments, reinstall
guard before operating machine. Failure to
comply may cause serious injury.
7.1 Blade gap tolerance
The notcher is pre-set for 3mm (12 ga.) workpiece
thickness, with 0.3mm blade gap tolerance. A
0.3mm feeler gauge is provided to assist in checking
this measurement. If notching workpieces 2mm
(14ga.) or thinner, adjust blade gap to 0.1mm, as
follows.
1. Press foot pedal to lower notching head;
continue pressing it.

Figure 8-3
8.0 User-maintenance
Disconnect machine from air
supply before performing any maintenance. If
head guard is removed for servicing, reinstall
guard before operating machine. Failure to
comply may cause serious injury.
1. Periodically insert oil into two fittings (A, Figure
9-1)
2. Periodically apply oil to pivot areas of
connection plate (B).
3. Drain water from air compress or tank daily, as
well as any condensation from air lines. Change
filters on the air system on a regular basis.
4. Periodically check filter/regulator bowl (F,
Figure 5-2) for fluids or sediment accumulation,
and empty if needed. Bowl should be emptied
before fluid reaches maximum drain level as
indicated on bowl. To remove a bowl, shut off
air supply and push pin (G, Figure 5-2) to bleed
excess air. Then press tab, rotate bowl to the
left, and pull bowl down. Reverse procedure to
reinstall bowl. Make sure bowl is locked in position before applying air to the system!
5. Maintain oil level in lubricator bowl (H, Figure 5-
2); top off as needed with ISO 32 (SAE 10) nondetergent, non-additive oil. Remove screw (J,
Figure 5-2) with screwdriver to fill.
6. Keep table and T-slots clean and free of rust.
Periodically apply a light coat of SAE 30 oil or
equivalent to exposed metal surfaces, such as
table, fences and blades.
7. Check air connections; replace components if
leakage is found.
8. Keep blade area free of deposits or shavings,
which can impede cut quality and hasten blade
wear.
9. Maintain sharp blades. If they become dull,
remove and re-sharpen.
