7.3B EIGHT AND TWELVE INCH BRAKE OPERATION
Hold short pieces with tongs or similar devices.
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.
CAUTION: NEVER PUT YOUR HANDS INTO OR AROUND A BRAKE WHILE IT IS IN
OPERATION.
Sticking can be caused by lack of lubrication, the complexity of the part being bent or bent guide pins.
Keep the guides well lubricated.
It is common practice to have the bottom die opening 8 times the thickness of the material being bent.
CAUTION: NEVER ATTEMPT TO FREE THE BRAKE BY HAND.
FOR TONNAGE REQUIREMENTS, SEE FIGURE 13 ON THE FOLLOWING PAGE.
If parts require bends less than 90 degrees, adjust the stroke 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 your local dealer.
CAUTION: ALWAYS REMOVE THIS TOOL WHEN IT IS NOT IN USE.
NOTE: If tool ever jams or gets stuck - REMOVE THE TOOL
FROM THE MACHINE BEFORE ATTEMPTING TO FREE IT.
