4.5 Operation 4.5
The VA (vertical action) cutting head holds two cutters which can be changed and used
independently of each other. Each of the standard GRAPHIK blade holders can be set
to cut at different depths and in either direction by simply adjusting or flipping the blade
over in the holder. You can also push or pull the cutting head to suit your own comfort.
Once your blade is set move the cutting head near to the start of the cut, press down
the blade holder and push or pull to take the cut. Only light finger pressure is usually
required to depress the blade holder so most of your effort can be directed into pushing
the blade through the material.

SCORING HARD PLASTICS
Many hard plastics such as Acrylic can be scored and snapped by hand or over the
edge of a bench (use hand and eye protection). The back edge of the GRAPHIK blade
can be used as a scoring blade, position the plastic sheet in the cutter and draw the
blade backwards across the surface applying downward pressure to the blade holder,
some plastics will benefit from being scored a number of times before snapping.
CUTTING PVC FOAMBOARDS
PVC is a very tough and durable material, to obtain a straight and smooth edge cut the
material slowly, if you cut too fast the board will rip and give a jagged uneven edge.
Considerably higher cutting performance is obtained from warm room temperature
boards, if you store your boards in an unheated room in winter you will find them much
more difficult to cut and the colder the board the slower they will need to be cut.
