Set The Blade Tension
Turn the blade tensioner clockwise to
increase the tension. Turn the knob
anticlockwise to lower the tension.
Raise the blade guard to its highest position
and increase the tension until it is only
possible to deflect the blade sideways by 2
to 3 mm at its midpoint between the table
and the guard.
Set The Blade Tracking
When fitting a new blade it may be
necessary to adjust the tracking (the
alignment of the top wheel).
The blade should sit on the centre or to the
front of the rubber tyre on the wheels.
To check the tracking, open both doors and
rotate the top wheel by hand.
If the blade starts to move towards the front
edge of the wheel, turn the tracking control
(located at the rear) clockwise.
Lock the tracking control in this position.
Set The Upper Blade Guides
The upper and lower thrust bearings
and blade guide pins should be set up
next.
Thrust bearing
Guide pin
Guide pin locking screw
The thrust bearing should be about
0.5 mm behind the back of the blade.
Adjust it and lock in place.
Slacken the guide pin locking screws
then adjust the pins so that there is a
clearance of 0.5mm either side of the
blade. Lock the pins in place with the
grub screws.
