Assembly
BLADE INSTALLATION AND ADjUSTMENT Correct clearances must be maintained for proper functioning of the tool and for clean cutting. To avoid accidents, always disconnect the tool from the power source while making adjustments
Insert lower shear blade in groove provided in the footplate and upper shear blade in groove of plunger. Finger tighten screws (A) and (B). Do not omit lock washer and flat washer for screw (A). When adjusting the lower blade, be sure plunger is at the bottom of the stroke.
UPPER BLADE – First bring the plunger into the top position by moving the fan blade with the pin provided. Move the upper blade until the vertical clearance between the blades is 1/64". After tightening the upper blade screw (A), tighten the setting screw with the pin provided.
The height adjustment of the upper blade is independent of the thickness of the sheet metal to be cut. For soft and malleable materials it must, however, in some cases be set lower, while for hard and brittle materials, it may be slightly increased.
LOWER BLADE – The horizontal clearance is directly related to the thickness of the metal being cut. Adjust clearance with the blade adjustment screw, then tighten the lower blade with the lower blade screw (B).
The clearance gap of the material being cut can be obtained with the help of the table provided below.
The recommended clearances are based on standard sheet metal specifications. For soft and tough materials (i.e. aluminum), reduce the recommended clearance. For hard and brittle materials (i.e. special stainless steel), increase the recommended clearance.
Gauge | Maximum Clearance | |
8 | (.164") | .032 (0.8mm) |
10 | (.134") | .024 (0.6mm) |
12 | (.104") | .020 (0.5mm) |
14 | (.074") | .016 (0.4mm) |
16 | (.059") | .012 (0.3mm) |
General rule: Max. clearance =
0.2 x material thickness.

Operating Instructions
GENERAL INFORMATION
Following a few simple tips will reduce wear on the tool and the chance of injury to the user.
With the tool unplugged from the power supply and the ON/OFF Switch in the “OFF” position, become familiar with handling the shear and learning the location of its parts.
Secure or clamp small workpieces to be cut to prevent slippage.
Inspect the blades for excessive wear, rotate or replace if necessary.
Always direct the cord toward the rear, and away from the shear. Keep it away from sharp edges.
Never start the shear with the blades in contact with the material being cut.
Do not exceed recommended capacities for this shear. Premature blade failure will occur when the shear is
To extend blade life and prevent corrosion, frequent lubrication of the blades is recommended. Any light weight machine oil can be used for this purpose.
SLIDE "ON-OFF" SWITCH
The Tool is switched "ON" by the slide switch located at the side of the motor housing.
TO TURN TOOL "ON": slide the switch forward.
TO TURN TOOL "OFF": slide the switch backward.
