Operations & Parts Manual
Air Shear
Installation
Always use clean dry air. Excessive moisture and dirt will
greatly reduce the life of any air motor. We recommend the
installation of an in-line filter-regulator-lubricator as close to the
tool as possible.
A 3/8" air hose is required up to a length of 8 ft. If more length is
required a 1/2" air hose should be connected to the 3/8" hose
to ensure the tool had the necessary air supply. Be sure all
hoses and fittings are the correct size and tightly secured.
Pre- Operation
Before the tool is connected to the air supply, clear the air hose
of accumulated dust and moisture. Before removing a tool for
service or changing accessories, make sure the air line is
shut-off and drained of air. This will prevent the tool from
operating if the tool is accidentally engaged.
Air tools require lubrication through-out the life of the tool.
Proper lubrication is the owner's responsibility. Failure to
lubricate and maintain the air tool property will dramatically
shorten the life of the tool and will void the warranty.
Designate a work area that is clean and well.
Secure loose work pieces using a vise or clamps (not included)
to prevent movement while working.
Never use the shear to cut heat treated, high carbon, or
spring steel. Personal injury can occur if air tool is used
on these steels.
Always wear gloves when using this tool to prevent
injuries from sharp edges or metal shavings
Before using the shear, make sure the blades (39, 40, and
41) are properly attached to the tool. Also, make sure the
blades are not dull, cracked, or bent.
Operation
1. Loosen head locking screw (37) and rotate shear head to
desired position. Retighten screw before use.

2. Place the center blade underneath the lip of the work piece.
Make sure the left blade and right blade are above the lip
of the work piece.
3. Press the trigger (2) to start the cutter action.
4. Position the cutter on the edge of the material to be cut.
5. Apply constant forward motion, but do not apply excessive
force or turn in either direction abruptly. The cutter will
break.
6. Always keeps the tool running when backing out from a cut.
The cutter will jam and break if the tool is not kept running.
7. Release the trigger and disconnect the air supply when
you change cutters or are finished with the tool
.
The blades will become hot while cutting. Allow the blades
to completely cool before touching
Allow the blades to move at full speed before feeding them
into the work piece. Do not force the blades into the work
piece when cutting. Apply moderate pressure, allowing the
blades to cut without being forced. Then turning off the
shear, allow the blades to stop on their own. Do not press
against the blades to stop them.
Maintenance
Blade Replacement
1. Always only use recommended replacement blade for this
shear.
2. Remove the head locking screws.
3. Remove the center blades first, then the left and right side
blades. Noting their orientation and spacer placement.
4. Reassemble in reverse order.
Lubrication
An automatic in-line filter-regulator-lubricator is recommended
as it increases tool life and keeps the tool in sustained
operation. The in-line lubricator should be regularly checked
and filled with air tool oil. Proper adjustment of the in-line
lubricator is performed by placing a sheet of paper next to the
exhaust ports and holding the throttle open approximately 30
.
seconds. The lubricator is properly set when a light stain of oil
collects on the paper. Excessive amounts of oil should be
avoided.
In the event that it becomes necessary to store the tool for an
extended period of time (overnight, weekend, etc.), it should
receive a generous amount of lubrication at that time. The tool
should be run for approximately 30 seconds to ensure oil has
been evenly distributed throughout the tool. The tool should be
stored in a clean and dry environment.
Recommended lubricants: Use Husky air tool oil or any other
high grade turbine oil containing moisture absorbents, rust
inhibitors, metal wetting agents and an EP (extreme pressure)
additive.
