Operation
1. Select the Punch and Die size appropriate for your job. Make sure that the
thickness of the work material does not exceed the recommended gauge for
the hole size.
Warning: Only use Punches and Dies of the same size together. Use of mismatched
tools will cause damage to the tools and the work material.
2. Use a 3/32 hex driver (not included)
to loosen both Hex Studs (10), so
that they will not interfere with the
insertion of the punch and die onto
the tool.
3. Insert the selected punch into the
same sized die. With the handles
closed, insert the punch and die
combination into the lower jaw, as
shown in the photo. Using the Key
(13), thread the die all the way into
the lower jaw until it stops. Using a
3/32 hex driver (not included), tighten both Hex Studs (10).
4. If you plan to make a row of holes a uniform distance from the edge of the work
material, set the Gauge (6) to the proper depth, and set it in place by tightening
the Screw (9) with the Key (13).
5. Carefully measure the desired position of the holes, and mark these positions
with a marker pen or scratch awl.
WARNING: The edges of sheet metal are often very sharp.Always use gloves
when handling sheet metal to prevent personal injury.
6. Before punching, it is a good idea to punch a test hole in a piece of scrap
material.

Maintenance
1. When not in use, store the punch in a clean, dry place. Maintain a light film of oil
on the punches and dies to prevent corrosion. Occasionally lubricate the hinges,
set screws and screw threads with light machine oil. Keep the rubberized
portions of the handles clean, dry, and grease-free.
2. Use only punches and dies specifically designed for this tool.
3. Over time the punches may become dull. Sharpen them using a low speed
method, such as dressing with a steel or oilstone. High-speed sharpeners may
overheat the tools, weakening them.
7. To punch, position the tool over the material, with the edge of the material
protruding into the throat of the tool. Align the punch with the spot marked on
the work material.
8. Using your hands, squeeze the Upper and Lower Handle (2 & 1) together, driving
the Punch through the work material. Release the pressure on the handles.
9. Punched out material (chads) may lodge in the punch. Use a small drift pin,
such as a nail set to knock the chads out. Do not use a punch that is blocked
with chads, as it may not punch cleanly.
WARNING: Keep your fingers, hair and clothing away from the jaws and hinges
of this tool when in operation. Fingers or clothing may be caught and pulled in
causing personal injury.
NOTE: Never use any tool such as a clamp, jack or vice to squeeze the handles
together, as this will cause damage to the tool, and potentially cause personal
injury or property damage.
