Operation
Cutting thick material using the ratchet latch
Ratchet latch
1. A unique feature of the Excalibur is the ‘ratchet latch’, this enables thick dense materials
such as PVC foam board to be cut easily in stages. Count the number of ‘clicks’ to position
the blade just below the surface of the material to make your rst cut then add an extra ‘click’
for the second and subsequent cuts.
2. Pull down the latch lever to disengage the ratchet if required.
As a rough guide when cutting PVC foam boards:
THICKNESS TAKE
3MM (1/8”) Initial surface cut + 1 additional cut
5MM (1/4”) Initial surface cut + 1 or 2 additional cuts
10MM (3/8”) Initial surface cut + 3 or 4 additional cuts
3. Should you engage the cutter by mistake or for any reason want to disengage the cutter
without moving it to the bottom of the machine pull down the cutter release lever.
4. For some operations (such as scoring acrylic) the ratchet latch needs to be disengaged, so
that nger pressure is used to make the score/cut. This is done by pulling the black knob on
the edge of the spring spool down to face towards the user. To re-engage the ratchet latch
push the small black knob away so it points upwards.
