Troubleshooting 3 SG9M Manual
Clamping plate does not drop when unclamped due to the improper adjustment of the four
clamping bolts.
- Adjust nylock nuts to set he correct clearance between the bottom side face of the locking T-Slot of the
floating base (Riser) and the top [art of the clampingplate. They are four clamping bolts on the SG8 and
two on the SG7. The dropping clearance when is on the floating mode should be 0.015” (0.38mm)on all
the four corners of the workhead clamping plate
Setting of the food pedal operated system actuated valve is misadjust
When the food pedal is not pressed, the clearance between the left valve plunger (when looking from the
front of the machine) and the food pedal bracket should be 0.010” (0.20mm) whereas the clearance
between the right valve plunger and the food pedal bracket should be 0.039” (0.75mm).
This can be achieve by loosing the two fixing screws and the adjusting the valve mounting bracket.
Tighten back the bracket ( see fig below).
When the food pedal is pressed, remove the black air tube from the left port and it should be a full air
flow, whereas when you remove the green air tube from the right port it should not be any air coming out.
