SOMETHING IS WRONG WITH THE CYLINDERS
THAT MOVE THE FRONT
SECTION
MOVE FRONT SECTION TO THE “IN POCKET POSITION” THEN DO THE
FOLLOWING:
1. Check to ensure that the 8” and 1 7/8” cylinders are all fully extended.
2. Check to ensure that the 1-1/4 cylinders are fully retracted.
ONE OF THE CYLINDERS IS BAD:
1. Check each cylinder on each front section assembly, looking/ listening for air
leakage from the seals, connecting air lines, valve bank that operates the
cylinder or cylinder stack.
THE ALIGNMENT OF THE CYLINDER SHAFTS IS OFF:
1. The shafts that connect the 8”, 1-7/8” and 1-1/4” cylinders together in order to
position the front section in different heights in order to perform various front
section functions must be perfectly aligned to prevent binding, which will cause
improper extension/retraction of the cylinders. Check the alignment and adjust
as necessary.
THERE IS AND OBSTRUCTION BLOCKING THE THROUGH BEAM:
1. Look to see if there is wood or tools blocking the free travel of the carriage.
Check that the air pressure is at operating specifications, and adjust as
necessary. Check the air cylinder to see if the seals are bad.
2. One of the router cords maybe dangling in front of a photo eye (or its line of
sight). Check to ensure that all router cords are properly tied out of the way.
GUARDS ARE MISS-ALIGNED:
1. Check that each of the guards is squarely positioned on the front sections(s);
adjust as necessary. This is a common problem if the guards were removed for
maintenance.
THROUGH BEAMS ARE NOT LINED UP:
1. The through beams, which focus through each of the four front section routing
assembly guards (through the holes drilled through the sides) must be
accurately aligned for proper operation. To make sure that your through beams
are correctly aligned by running a piece of string from one photo eye, through
each of the router guards to the photo eye on the other end of the machine.
Check to ensure that the string aligns directly from the center of the photo eye
lenses, through the center of the holes, on a level plane. If they don’t then
adjust the photo eye brackets until they do.
2. Alignment can only be accomplished when the front section is up and ready to
go into the pocket. Loosen the (2) ¼-20 bolts on the photo eye brackets to
adjust.
