OPERATIONS
After switching between planing and molding operations,
you must re-adjust the feed roller height and spring
tension, so the workpiece is drawn through the planer/
moulder without chatter or slip. Rollers that are too high,
or have light spring tension can cause workpiece chatter
or slip. Feed rollers that are too low or have excessive
spring tension can make workpiece insertion into the
planer/moulder difficult, and prematurely wear the feed
roller shafts and bearings. The settings below are starting
points and some trial-and-error when adjusting will be
required.
To adjust the feed roller height and spring tension, do
these steps:
1. DISCONNECT MACHINE FROM POWER!
2. Loosen the lock nuts (see Figure 28) and rotate the
eccentric stops with a 5mm hex wrench until the
rollers are positioned as follows:
—For planing, lower the roller approximately 1mm
below the lowest sweep of the planing knife.
—For moulding, lower the roller approximately
3
⁄16''
below the highest point of the moulding knife
profile. Refer to Figure 29 to find the highest point
of the moulding knife profile when the knife is at
the lowest point of its sweep.
