When the blade becomes worn or defective in any way it should be replaced
immediately. The following process details how to change the blade, and should
be carried out by a skilled technician only.
Once the blade has been replaced it is recommended that the blade is Run In for
a short period.
1. Ensure the machine is disconnected from the mains supply then raise the Arm
to its vertical position and lock in place using the lock provided (item T).
2. Undo the screws securing the blade guard cover (item44) andf hinge the cover
back. Remove also the blade guard attached to the Blade Guide assembly.
3. Turn the Blade Adjuster Knob anticlockwise in order to remove all tension from
the blade, allowing it to be pulled from the pulleys and from between the guide
