ADJUSTMENTS
8.1 HEIGHT OF CUT
The height of cut can be set between:
13mm (1/2in) and 51mm (2in) (61mm on the spanner
adjust) on the Magna 250 fixed head.
13mm (1/2in) and 35mm (1 3/8in) on the Sport 200
floating head standard blade.
TO ADJUST HAND WHEEL TYPE:
1. Turn the adjuster handwheel (A) clockwise to
increase the height of cut, or anticlockwise to decrease
the height of cut.
2. Ensure that an equal amount of adjustment is made
to both adjusters on all the cutting units. To assist in
obtaining equal adjustment height of cut indicators (B)
are provided at each end of the roll assembly.
NOTE: The numbers 1 to 9 are only for reference from
one side of the roll to the other and bear no relation to
the height of cut other than each graduation gives
approximately 6.25mm (1/4in) height of cut movement
for fixed head units and 3.75mm (5/32in) for floating
head units. These indicators are set at the factory and
when the pointer is set the same at each end of the roll
the roll will be parallel with the bottom blade. If due to
any reason the roll and bottom blade are not parallel
with each other the roll can be set parallel with the
bottom blade by rotating one of the handwheels and
then one indicator adjusted by slackening the small
clamping screw in the centre of the indicator plate and
positioning the indicator relative to the pointer at the
opposite end of the roll assembly.
3. No other adjustments are necessary.
4. THIS IS A SELF LOCKING MECHANISM THERE
BEING NO NECESSITY TO UNLOCK OR LOCK THE
MECHANISM.
TO ADJUST SPANNER TYPE:
1)
Release the two screws (C) which hold the
eccentric bush in the lever.
2)
Turn the adjuster (B) at the rear of the unit,
clockwise to reduce the height of cut, or
anticlockwise to increase the height of cut.
3)
After adjustment tighten screws
(C) to a maximum torque of 17Nm.
