ADJUSTMENT
SPORT 200 FIXED HEAD ADDITIONAL
ADJUSTMENT
1. Accommodation for extra high height of cut
adjustment is built into the cutting unit centre pivot.
2. By repositioning the rear centre pivot bolt height
of cut up to 101mm (4in) can be achieved.
SPORT 200 FLOATING HEAD FRONT ROLL
SETTING
1. The right hand end of the front roll is fixed. To
set the roll parallel to the bottom blade rotation of
an eccentric clamping nut on the left hand front roll
bearing housing is necessary.
2. Slacken left hand roll bearing housing clamping
bolts.
3. Rotate the eccentric nut to give the desired
parallelism of the roll to the bottom blade.
4. While still holding the eccentric nut from rotating
tighten the the roll bearing housing clamping bolts.
CUTTING CYLINDER TO BOTTOM BLADE
ADJUSTMENT (FIG.6)
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 HAND WHEEL TYPE:
1. To adjust the cylinder to the bottom blade turn
alternately left and right hand handwheels (C Fig.6)
clockwise to put on cut. A 'notching' effect will be
felt as the handwheel is rotated in a clockwise
direction this 'notching' is moving the cylinder in
increments of approximately 0.035mm (0.0014in)
towards the bottom blade.
2. The correct 'on cut' must be achieved with the
adjustment mechanism 'slack' (i.e. between
'notches'). A requirement of the hand adjustment is
that the cylinder must always be moved towards the
bottom blade (i.e. clockwise rotation of handwheels)
