There is an obstruction between beam
guards.
Beam Guards
When there is an obstruction on the optical line
between beam guards, the beam is blocked and
safety function operates. Therefore, knife does
not lower.
There is trouble with foot switch control
board.
If board is replaced and problem disappeared,
some of relays on the board has the contact
failure.
Some of switches on operation panel remains
on.

Any of the step forward button, the size
memory button, and the push-out memory

the setting mode. Therefore, hydraulic system
does not operate.

Cement Resistance
SSR (solid stay relay) or cement resistance is
damaged.
If its white exterior is broken or cracked be-
cause of heat, cement resistance get damaged.
And if there is continuity between the two
parts of the bottom in the following drawing,
SSR is out of order. However, no continuity
does not always mean normal.
If there is continuity,
SSR is out of order.
If this part is damaged, hydraulic pressure is
not applied. Replace the board.
If knife does not lower though hydraulic
pressure applied, check the hydraulic valve.
