Adjustments
This chapter illustrates the regulations and adjustments of the mechanical
systems (pneumatic systems in the MA version) for correct use of SHARK 282.
These instructions will enable you to “customise” your machine to suit the type of
cuts you want, optimising the time required to complete them.
Air treatment unit (MA version)
In the MA version of the SHARK 282, the machine’s pneumatic circuit actuates
the vice by means of a pneumatic cylinder.
The compressed air is treated and purified at the inlet to the system by an air
treatment unit, which, if so calibrated, regulates the pressure at about 6 Bar,
irrespective of the pressure in use i n the factory circuit.
The pressure can in any case be set should the workpiece be s ubject to deforming
stress or is unstable during the cutting process; the vice should be positioned at
23mmfromthepiecebeforefinalclamping.
The user is requested to have available in the workshop a plant having the
characteristics described in CHAPTER 4.
The diagram below shows an exploded view of the air treatment unit: the working
pressure is regulated by rotating the knob indicated by the arrow, and is displayed
on the pressure gauge.
