ƒ After scribing a clear line, use an open or boxend 1/2" wrench to remove
the two nylock nuts. VERY IMPORTANT: Count the number of turns
from the scribed reference lines it takes to remove the nuts. When
reassembling, this count will be used to recalibrate the air bladder back to
the original setting.
ƒ Remove the nylock nuts, but be careful to keep them in a way that they
do not get mixed up. It's important that the nuts go back on the bolts they
came off of.
ƒ With the nylock nuts removed, you can lift the air bar off of the air
bladder enough that it clears the drill frame.
ƒ Turn the air bladder and the air bar counter-clockwise until you hear the
SQE fall inside the machine.
ƒ Reach inside the rear of the machine with one hand (or get assistance)
and turn the air bladder with the other until the SQE is fully unscrewed
from the air intake for the bladder.
ƒ Disconnect the large air hose from the push-in fitting attached to the SQE
and remove the SQE from the rear of the machine.
Index Pins are not Coming Back Up
Begin by checking the Air Pressure at the Secondary Regulator.
ƒ Refer to Machine Adjustments for the Instructions
After you have checked the regulator you will next want to check the hoses at the
secondary regulator. The hoses that supply the air to the Index Pins run from the
secondary regulator. These hoses run through the Guard Frame and are visible
when looking into the opening at the rear of the machine.
ƒ Use a bright light to trace the hoses from the secondary regulator to the
white & black barbs on the Index Pins.
