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).
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
10:17 AM Page 7
Assembly
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.

Operating Instructions

contact with the material being cut.
Do not exceed recommended capacities for
this shear. Premature blade failure will occur
when the shear is over-gaged.
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.
