TROUBLESHOOTING
If the machine is having difficulty adjusting for lateral run-out, first assess the vehicle being serviced. If
lateral movement is rough or uneven due to damaged vehicle components, these components must be re-
paired or replaced before rotors are match-machined. It is also important that the machine be supported
by the trolley during adjustment.
LATERAL Run-out ADJUSTMENT The 9.2DRO can be calibrated to adjust to tighter or looser standards.
TIGHTENING THE GIB
Poor finish quality can be the result of a loose cutting head. As wear occurs between the slide plate and the gear box
it rides on, you must take up the slack. You do this by tightening the moveable wedge we call the “gib”
(50-463). If
the cutting head can be moved from side to side at all, it should be tightened.
To reattach the feed block, move the slide plate as far forward as it can travel, wind the feed block in to meet the plate,
and then install and tighten the two 6mm allen cap screws. This ensures that the feed block will be properly centered.
Wind the head back out and the machine is ready for use.
First loosen all five set screws (with 2mm allen wrench) by freeing the 8mm lock
nuts and loosening the allen set screw s, and remove the 2 feed block screws with
a 6 mm allen wrench.
Remove the
50-496 plate and gib completely, and clean the contact surfaces.
Locate the plate in the middle of the rail with the gib between the plate and the
rail. Be sure the 5 notches of the gib are aligned to catch the allen set screws as
they’re tightened through the plate.
Tighten each allen set screw until you feel it snug against the gib.
Hold light pressure with the allen wrench as you lock the screw down with the
8mm lock nut.
After tightening each nut, slide the plate to make sure there is no binding. When
the gib is adjusted properly, the plate will have some resistance as it slides, with
no lateral movement possible.

CALIBRATION PROCEDURE
The Pro-Cut 9.2DRO Rotor Matching System is calibrated with an acceptance
number from the factory. Normally, this will never need to be changed.
Please
call Pro-Cut Service Department before attempting calibration procedure to
confirm that this is the problem. To tighten the calibration you need to lower
the acceptance number. To
loosen the calibration, you need to raise the ac-
ceptance number.
Please see pages 34 - 35 to raise or lower the acceptance number.
