7.5B BRAKE OPERATION
NEVER PUT YOUR HANDS INTO OR AROUND A BRAKE WHILE IT IS IN OPERATION.
Grease the slider block between the upper arm and the tool every two hours of operation.
Hold short pieces with tongs or a similar device. In using the brake, it is necessary to load the brake
centrally. (Visual centering is sufficient.) If work is performed off-center, the guide pins could be
damaged. The brake lift is provided by springs. If sticking occurs at the bottom of the stroke and the
upper die does not return, usually a slight tap on the upper die is sufficient to free the guides.
DO NOT ATTEMPT TO FREE THE BRAKE BY HAND.
Sticking can be caused by lack of lubrication, complexity of the part being bent or bent guide pins. Keep
the guides well lubricated and replace them if they are damaged.
It is common practice to have the bottom die opening 8 times the thickness of the material being bent. If
the parts require a bend of less than 90 degrees, adjust the down stroke of the machine until the desired
bend is obtained.
A great variety of standard brake dies can be used with this unit. These are available from Scotchman
Industries or Brake Die suppliers. REMOVE THE TOOL WHEN IT IS NOT IN USE.
