9.8 CUTTING CYLINDER TO BOTTOM BLADE
ADJUSTMENT
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.
To adjust:
1. To adjust the cylinder to the bottom blade lift and
turn alternately left and right hand
handwheels (A Fig.3). (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.
