For Your Own Safety Read Instruction Manual
Before Operating This Equipment
The purpose of safety symbols is to attract your attention to possible hazard-
ous conditions. This manual uses a series of symbols and signal words which
are intended to convey the level of importance of the safety messages. The
progression of symbols is described below. Remember that safety messages by
themselves do not eliminate danger and are not a substitute for proper accident
prevention measures.
Indicates an imminent hazardous situation which, if
not avoided, WILL result in death or serious injury.
Indicates a potentially hazardous situation which, if
not avoided, COULD result in death or serious injury.
Indicates a potentially hazardous situation which, if
not avoided, MAY result in minor or moderate injury.
It may also be used to alert against unsafe practices.
This symbol is used to alert the user to useful infor-
mation about proper operation of the equipment.

section 2: setup
unpacking
assembly
your tool was carefully packaged for safe
transportation. remove the packaging
materials from around your tool and inspect
it. if you discover the tool is damaged,
please immediately call Customer Service
at (570) 546-9663 for advice.
to assemble the pneumatic shear:
1. remove the plastic plug from the air
inlet in the handle.
2. Apply pipe sealant on the threads of
the quick disconnect fitting.
save the containers and all packing
materials for possible inspection by the
carrier or its agent. otherwise, filing a
freight claim can be difficult. When you are
completely satisfied with the condition of
your shipment, inventory the contents.
3. thread the fitting into the pneumatic
shear air inlet and tighten.
4. press the trigger, and place a few
drops of air tool oil into the air inlet,
and release the trigger. the pneumatic
shear is ready for use.
if any non-proprietary parts are missing
(e.g., a nut or a washer), we will gladly
replace them; or for the sake of expediency,
replacements can be obtained at your
local hardware store.
air supply setup tips:
•
if the air hose is longer than 25-feet,
increase the air pressure to 100 psi to
compensate for air flow restriction.
•
•
For consistent air flow, use air hoses
with an inside diameter of 3⁄8" or larger.
inventory
to eliminate air system moisture and
maintain automatic lubrication, install a
main or in-line filter water separator as
far as possible from the air compressor,
but before any automatic in-line oiler.

section 3: operations
operation overview
to complete a typical cutting operation,
the following is done:
1. put on safety goggles and gloves.
2. Mark the cut line, secure the workpiece,
and clamp a guide to the workpiece if
this tool presents serious injury

3. determine if the swivel head needs to
be rotated for optimum tool control and
cut line viewing.
•
if so, loosen the swivel head cap
screw (see figure 1, on page 5),
rotate the head to the required
angle, and retighten the cap

lubrication
daily maintenance
in most cases for perodic tool use, manual
lubrication is sufficiant. however, if the tool
is to be used on a consistent basis, we
recommend installing an automatic oiler to
eliminate dry runs and ensure maximum
tool life. the two methods are explained
below.
before and after each use:
•
Check and replace any leaking air
fittings; bubbled, cut, or worn hoses.
•
drain water from the compressor tank,
water filter separator reservoirs, and
lubricate the pneumatic shear.
Manual Lubrication: every two hours of
use, place a few drops of air tool oil in
the air inlet fitting and at all pivot points.
do not use motor oil as the additives can
corrode the tool seals. next, connect the
tool to the air line and cover the exhaust
port (see figure 1, on page 5) with a rag.
position the end of the tool safely away
from you, and run the tool for 30 seconds
to completely circulate the oil through the
tool and into the rag.
periodically as required:
•
Clean the filter screen behind the air
inlet fitting (see figure 1).
•
if used, check and adjust any automatic
in-line oiler as required to maintain a
fine oil mist at the tool.
•
sharpen dulled jaws edges by removing
both jaw retaining cap screws (see
figure 1), and the jaws. next use a
dressing stone at the locations shown
below. do not use a grinder.
Automatic Lubrication: Adjust the
automatic in-line oiler. place a sheet of
paper next to the exhaust port, run the tool
at three or four 30-second intervals. When
finished, the paper should show a slight oil
stain. if no oil is seen or excessive oil drips
from the paper, adjust the oiler and repeat
this process until the adjustment is correct.
