HOLD DOWN ALIGNMENT:

 

The forward edge of the fingers / nose bar on the hold down assembly should 

be even and parallel to the edge of the clamp block on the base. Release any clamping pressure on the hold 
down assembly by pushing the clamp handles slightly to the rear. Loosen the set screw located on each end of 
the hold down assembly and turn the eccentric to move the forward edge of the clamp block. Check to see that 
the edge of the hold down is flush with the edge of the block throughout the entire length of the brake. The 
central portion of the hold down assembly can be adjusted forward / backward and up or down via truss rod 
adjustment.

DO NOT

 

USE THE BRAKE TO BEND RODS, NAILS OR WIRE. THIS WILL CAUSE DAMAGE TO THE 

EDGE OF THE NOSE BAR AND APRON. 

 

ALWAYS

 

ADJUST THE CLEARANCE AND CLAMPING PRESSURE FOR DIFFERENT THICKNESSES OF 

MATERIAL. 

 

DO NOT

 

EXCEED THE CAPACITY OF THE BRAKE. MAKE CERTAIN THAT APRON SUPPORT ANGLE 

AND APRON INSERT IS ATTACHED TO THE APRON ASSEMBLY WHEN MAKING CAPACITY BENDS. 

OTHERWISE PERMANENT DAMAGE TO THE APRON MAY RESULT. 

 

DO NOT

  

bend seams, hems of locks unless the material is notched or the clearance is adjusted to double the 

seam/hem thickness. The capacity of this brake is 22 gauge (0.030). Multiple layers of material which exceed 

this dimension are beyond the capacity of the brake. 

 

DO NOT

 

USE PIPE EXTENSIONS TO GAIN ADDITIONAL LEVERAGE ON THE CLAMP HANDLES.
