8. PRESSURE PAD

8.1

The purpose of the Pressure pad is to insure that the Terminal stays in the correct

position over the anvil when the Feed finger is moving backwards, the pressure on the

terminal can be adjusted by loosening the 2 x M5 locking nuts and either tightening or

loosening the 2 x M5 adjustment screws as shown below.

M5 adjustment Screws

M5 Locking nuts

Pressure Pad (161)

Thumb Screw
