CUTTING CYLINDER TO BOTTOM BLADE
ADJUSTMENT (FIG.47)
To check that the cutting cylinder is set to the bottom
blade correctly, hold a piece of thin paper between the
edge of the blade and the spiral cutters and turn the
cylinder manually.
The paper should be cut cleanly along the total length
of the bottom blade, if not, some adjustment may be
necessary, BUT DO NOT OVERTIGHTEN.
Alternatively if the cylinder is worn it may require back
lapping before adjusting, see page 60.
To adjust:
1. To adjust the cylinder to the bottom blade lift and
turn alternately left and right hand handwheels (A
Fig.47). (clockwise to put on cut anticlockwise to take
off cut) and release, keep turning the handwheel until
it locates in the serrated locking ring. The adjuster is
of the notched type and each notch is moving the
cylinder in increments of approximately 0.04mm
(0.0015in).
THIS IS A SELF LOCKING MECHANISM THERE
BEING NO NECESSITY TO UNLOCK OR LOCK
THE MECHANISM.
IMPORTANT: IN ROUGH GROUND CONDITIONS
IT MAY BE NECESSARY TO LOCK THE NUTS
SECURING THE BEARING HOUSINGS TO THE
SIDE FRAME WHERE THEY RUN IN ADJUSTING
SLOTS TO RETAIN CYLINDER TO BOTTOM
BLADE SETTINGS. EXPERIENCE WILL DICTATE
THIS. THE NUTS SHOULD NORMALLY BE
TIGHTENED FULLY AND THEN BACKED OFF 1/2 A
TURN TO ALLOW HANDWHEEL ADJUSTMENT
WITHOUT THE NEED TO UNLOCK THE NUTS
FIRST.
CUTTING CYLINDER BEARINGS
