INSTALLATION

UNPACKING
Use caution in handling and movi ng the foot shear . T he foot shear weighs 875 pounds an d is top-heavy.

Handling should be performed with proper equipment such as a fork lift.

• Insert forks UNDER main table to lift and move.

INSTALLATION

Locate the brake in a well-lighted area on a solid level floor.
NOTE: The Foot Shear is provided fully assembled.

BEFORE USING!!!

Machine should be set up on as FLAT
of surface as possible.

Use Levelling Foot Pad Screw to bring
side plates to exactly 90˚. This will bring
the sides to parallel and insure that the
Upper Blade Holder moves up and down
smoothly. Lock the jam-nut on the foot
pad. Check the action of the shear by
carefully depressing the treadle and
checking for binding.

Level
90˚

Screw

• Place Smart Tool, Level, / Angle Finder on vertical frame
and resting on edge guide plate –
see photo.

• Adjust Leveling Mount on each front frame leg until each
side reads 90-degrees to parallel frame, so upper blade
holder moves up & down smoothly.

• Tighten jam nut on Leveling Mount.

• Carefully depress the shear foot treadle to check for

binding.

SHEAR BLADE CLEARANCE
CAUTION: CHECK SHEAR BLADE CLEARANCE BEFORE OPERATING FOOT SHEAR

• Depress Foot Treadle and hold on fl oor .

• Place 0.003” feeler gauge between the upper & lower shear blades – approach blades fro m

machine rear.

• Check Blade Clearance at: 6” from left end / center / 6” from right end.

• NOTE: Blade Clearance is factory set at 0.003”.

GENERAL RULE - BLADE CLEARANCE = 5% - 10% OF MATERIAL THICKNESS.

Aluminum = 5% of material thickness.
Mild steel = 10% of material thickness.

CAUTION: Too Narrow or Too Wide shear blade clearance can cause
blade and/or machine damage.

OPERATION

• Place Metal on table and align with Edge Guide Plate on left side or right side.

• Align metal with edge guide plate scale or marks on metal where metal is to be cut –

Align Both Sides.

• NOTE: Look between infeed guard and Upper Blade Holder Assembly to align marks on metal with
lower shear blade edge.

• Push Foot Treadle down to lower Upper Shear Blade Assembly to cut metal.
NOTE: Push Foot Treadle to floor to insure entire metal width has been cut.

• Release Foot Treadle – Spring Loaded Upper Shear Blade Assembly will move upward to home

from machine rear.

• Check Blade Clearance at: 6” from left end / center / 6” from right end.

• Turn Allen screws on each side (2) clockwise until screw contacts table front – holds table in

secure position.

• Tighten jam nuts on each side (2).

Close Shear Blade Clearance:

• Turn allen screw clockwise to move table forward and close clearance between upper/lower shear

blades until desired clearance is achieved.

• Place desired thickness feeler gauge between the upper & lower shear blades – approach blades
from machine rear.

• Check Blade Clearance at: 6” from left end / center / 6” from right end.

• Tighten jam nuts on each side (2) when desired blade clearance is achieved.

• Turn hex head bolts on each side (2) clockwise until bolt contacts table front.
