Model T32719 (Mfd. Since 06/21)

adjusting clamping pressure

Clamping pressure must be properly adjusted for 
different  workpiece  thicknesses.  The  ideal  pres-
sure will have medium resistance at the clamping 
handles, and will lock the workpiece into position 
easily—much like a pair of Vice-Grips

®

. Pressure 

is  adjusted  by  rotating  the  adjustment  nuts  on 
the  clamping  pressure  adjustment  rods  (see 

Figure 14). These are located on both ends of the 
pan and box brake.

Item(s) Needed: 

Qty

Open-End Wrench 17/19mm ............................. 1

To adjust clamping pressure:

1.   Lower clamping leaf so clamping fingers just 

touch workpiece.

 

Tip:  It is best if the  workpiece used in this 
procedure  is same width as pan and box 
brake. If not, place two pieces of metal of 
same thickness as workpiece on each end of 
brake.

— If  clamping  handles  are  at  10  o'clock 

(viewed  from  right  end  of  brake)  and  2 
o'clock  (viewed  from  left  end  of  brake) 
position,  then  clamping  pressure  is  suit-
able for workpiece. Proceed to 

Step 4.

— If  clamping  handles  are not  at  10  o'clock 

(viewed  from  right  end  of  brake)  and  2 
o'clock  (viewed  from  left  end  of  brake) 
position,  then  clamping  pressure  is  not 
suitable for workpiece. Proceed to 

Step 2.

2.  Loosen  adjustment  nuts  (see  Figure 14) 

and turn both sets up or down until clamping 
handles are in 10 and 2 o'clock position when 
clamping fingers just touch workpiece.

3.  Tighten  adjustment  nuts  to  secure 

position.

4.  Make sure clamping pressure is even on both 

ends  of  brake  by  raising  one  end  and  test-
ing  clamping  action  of  other  end.  Clamping 
action should be same on both ends.

5.  If  necessary,  repeat  Steps 1–4  until  proper 

clamping pressure is achieved.

 

Note: Proper clamping pressure is achieved 
when  the clamping handle "snaps" (or 
locks) into position against handle stop (see 

Figure 14).
