SQE Check
The SQE may need to be cleared if the head is not operating normally. Occasionally debris will work
it’s way in and keep the air from flowing freely. This clearing can only be done by first removing the
rear stop.
SOLUTION STEPS:
1. Make sure the machine power is off and the air is disconnected
2. Locate the Fixed Rear Stop. It is held in place by two 7/16" nylock nuts on the underside
of the stop.
3. Remove the stop, but DO NOT adjust the Rear Stop bolts sticking out of the rear of the machine
that butt up against the rear stop.
