Bead Breaker   

The  bead  breaker  is  on  the  right  side  of  the 
cabinet.    As  the  procedure  requires,  depress 
pedal  I  (Fig.  05)  to  work  the  cylinder,  the  piston 
will  move  the  bead  breaker  arm  towards  the 
direction  of  the  cabinet.    The  breaking  force 
should be around 14075N (5,620 lbs).    Release 
pedal  I,  the  piston  will  move  in  an  outward 
direction.   

The  bead  breaker  shovel  is  allowed  to  swing 
within  a  certain  range.    In  case  the  distance  of 
swing is not appropriate, adjust the nut (Fig.09) at 
the right end of the piston rod.

Hexagonal Column Clamping System   

The  Hexagonal  bar  (shown  in  Fig.10)  can  move 
up  and  down  freely  while  the  Hexagonal  bar 
locking handle is in the downward position. While 
the Hexagonal bar locking handle is moved 120° 
or so, the cam connected with the handle will lift 
the  locking  plate  to  lock  the  Hexagonal  bar.  If  it 
does not lock, you can adjust the bolt’s position to 
assure the locking.

Air  Pressure  Regulator,  Gauge  and 

Lubricator Assembly 

As  shown  in  Fig.11,  there  is  a  knob  for  the 
regulator.    When  pulled  up,  the  pressure  can 
be  increased  or  decreased  by  turning  it 
clockwise 

or 

counter-clockwise. 

 

After 

adjusting the operating pressure, press the knob 
down to lock it.     

The  air  separator  works  to  filter  the  water  and 
impurities in the  compressed air.    When water 
and impurities are above the red line, open the 
drain valve to release them.     

The  lubricator  is  used  to  add  a  certain  amount 
of  lubricant  into  air  for  the  moving  parts  in  the 
cylinder  and  regulator.    Depress  pedal  H  or  I, 
3

5 times, a drop of oil will drop into the cup in 

the  regulator.    If  it  doesn’t  happen,  the 
adjusting screw can be used adjust the output to 
specification.
