MACHINE SET UP
The first time these operations must be performed by qualified personnel in the presence of the operator
in charge. (Standard EN 292-2 art. 5.5 1d)
6.01 REGULATIONS
ATTENTION
The Matest Gyratory Compactor is calibrated at the factory to perform a set
gyration angle (lock position “1B”) and null angle (lock position “1A”). The
gyration angle can be changed within a working range acceptable for the
machine, adjusting the two dowels and nuts (“2” and “3”) placed on the selector. N.B.: THE MACHINE
CALIBRATION DECAYS IF THE FACTORY SETTINGS ARE CHANGED.
The gyration angle is set by the
hand grip selector that moves
vertically
2 of the
5 wheels
conceived to guide the mould.
The selector enables the operator to
set two working positions:
•
the gyration angle
•
the null angle
When the machine is off the
operator can set the gyration angle
by turning the hand grip “1” of the
selector clockwise up to the lock
position “B1” (the wheels moves
vertically upwards), or can set the
null angle at lock position “1A” by
turning
the
hand
grip
counterclockwise (the wheels moves
vertically downwards).
Being the Gyratory Compactor calibrated at the factory, we recommend to set the
angle at lock position “1B” without introducing the mould into the machine. If this
condition is followed, the operators can insert the mould, perform the test and then
take out the mould from the machine without adjusting the selector.
If necessary, the operator can set the angle even after a pre-compaction of the
specimen using the null angle. In this case the rotation of the hand grip may be
difficult and a monkey wrench may be necessary to adjust the angle.
6.02 CHECKING THE SAFETY DEVICES WORK
Before proceeding to a regular and continuous use of the equipment, check the
emergency stop works correctly by: starting and stopping the machine through the
main switch, starting the machine and opening the doors, starting the machine and
pressing the emergency button.

IN FUNCTION - USE
DANGER
WARNING
Before setting the machine in motion it is essential that the Operator and
Safety Manager have read the Instructions Manual and understood all parts
of the machine and activities linked to it (Risks, Dangers, Functionality,
Operation, Protections, Commands, etc.)
7.01
MACHINE CALIBRATION – METERS - INDICATORS
The machine is checked in the factory, using sample equipment periodically checked by officially recognised
institutes. These checks cannot guarantee that the machine, meters and indicators will provide accurate values
and results conforming to the standards in force in the countries the machine has been installed and used in.
Normally such norms envisage calibration check after every movement. In order to obtain correct values and
results it is therefore VITAL that the operator, once the machine has been installed and set up and before official
tests, has an officially recognised body check the machine characteristics, its calibration and results/values
reliability. The manufacturer is exempt from all responsibility in the case of direct and indirect damage from use of
the machine without officially approval by the relevant bodies.
