REEL TO BEDKNIFE ADJUSTMENT

To check that the reel is set to the bedknife correctly,
hold a piece of thin paper between the edge of the
blade and the spiral cutters and turn the reel
manually.
The paper should be cut cleanly along the total length
of the bedknife, 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:
To adjust the reel to the bedknife 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 REEL TO BEDKNIFE
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.
