READ INSTRUCTIONS
• Thoroughly read and understand these product instructions before using
this tool.
• Keep these product instructions for future reference.
EYE INJURY HAZARD!
• Rapidly reciprocating Blades will eject metal chips at high velocity.
Always wear ANSI approved eye protection when operating this tool.
HEARING DAMAGE HAZARD!
• The Eastwood Pneumatic Metal Shear emits high sound levels while
operating. Use ANSI approved ear protection when operating this tool.
BURST HAZARD!
• Do not exceed 90 psi (6.2 bar) of tool inlet pressure. Permanent tool damage
and/or bursting could occur and cause personal injury.
INJURY HAZARD!
• This tool has high-speed cutting surfaces which can quickly cause severe
injury. Keep fingers and hands away from moving parts when operating.
• Handling sharp metal can cause severe cuts. Wear thick, well-fitting
work gloves.
• Do not force tool or exert excessive force on Blades while cutting as the tool
body can suddenly kick back or twist causing severe hand or wrist injury.
• Always disconnect tool from air supply when changing Blades to prevent
accidental tool starting and potential severe injury.
• Always make sure the workpiece being cut is securely clamped or anchored
to avoid sudden movements which could result in injury.
• Frequently inspect Cutting Blades and tool condition. If cracks or chips
develop, discontinue tool use immediately and replace damaged Blade Set.
USE ONLY an Eastwood #13474 Pneumatic Metal Shear Replacement Blade
Set. Severe injury can result in the event of a Cutting Blade failure.
VIBRATION INJURY HAZARD!

EYE INJURY HAZARD!
Rapidly reciprocating Blades will eject sharp metal chips out of the front at
high velocity. Always wear ANSI approved eye protection when operating
this tool.
DO NOT attempt to exceed 18 Gauge (0.050”) [1.2mm] mild steel, aluminum
and copper or 20 Gauge Maximum (0.036”) [0.91mm] for stainless steel.
POSITIONING CUTTING HEAD
The Cutting Head may be rotated 360° in relation
to the Handle of the Shear Body to accommodate
cutting in difficult to reach areas. To do so:
• Using the included 4 mm Hex Key, loosen
(but do not remove) the three socket head
cap screws on the Cutting Head adequately
to release clamping pressure (FIG 1).
• Rotate the Cutting Head about the axis of
the Shear Body to the desired position then
re-tighten the three screws.
SET-UP & CONNECTION
• Be sure that the air supply to the tool is clean and dry. Moisture in the supply line will quickly
damage the motor and valves.
• A minimum 3/8” I.D. air line should be used for optimal performance.
• Thread the included 1/4” Male Quick-Disconnect Fitting into the air inlet of the tool using a
quality thread sealing tape (not included).
OPERATION
• Place the cutting blades against work piece and depress trigger to actuate cutting.
• Always maintain a firm grip while operating tool, do not force but allow the reciprocating action
of the Cutting Blade to do the work.
• Be sure that the workpiece is clamped down or held securely to minimize the danger of injury
while operating tool.
INJURY HAZARD!
This Metal Shears can quickly start up when handling while connected to an
air supply causing serious personal injury. Always disconnect the tool from the
air supply before changing Cutting Blades or performing maintenance.

• If tool is to be unused for an extended period, add 10 drops of air tool oil directly to the air
inlet and store the tool, air inlet up.
• Frequently, with the air supply disconnected, inspect Cutting Blade condition and tightness.
