18. Using the hydraulic pump on the optional hydraulic lift undercarriage,
adjust the working height of the machine to suit the height of the work
table (the top of the Main Roller, after adjusting to desired bevel
depth, is to be the same height as the underside of the plate to be
bevelled). To lower the working height of the machine, slowly push
down on the pump release leaver located on the pump body. Pull up
on the release leaver once the desired height is reached.
19. Check that the Guide Rollers are correctly adjusted. The intent of the Guide Rollers is to
reduce drag caused by the plate feeding through the machine. This is achieved by the plate
running against these free moving bearings which are slightly in front of the Guide Roller
Bracket, and thereby reducing the surface contact with the face of the Guide Roller Bracket.
For plates with straight edges, the Guide Rollers should be slightly in front of the face of the
Guide Roller Bracket, by approximately 0.020” [0.5 mm].
For plates with concave edges
(i.e. bevelling the inside diameter
of a large disk) the Guide Rollers
will need to be set further back
(in towards the machine).
For plates with convex edges
(i.e. bevelling the outside
diameter of a large disk) the
Guide Rollers will need to be set
further forward (out from the
machine).
To adjust the Guide Rollers,
follow the procedure on the
following page.
