7.3
USING THE MICROMOTOR
Before using the machine, make sure the
speed regulator knob (Fig. A, 2) is turned fully
anticlockwise.
Fig. 6: The H-F selector (6) on the ARIO 35 laboratory
micromotor enables the machine to be used in two
different operating modes:
1. Selecting the H command: tool rotation speed is always
as set by the speed regulator (Fig. A, 2) (see paragraph
7.3.1).
2. Selecting the F command: tool rotation speed is always
as set by the speed regulator (Fig. A, 2), but rotation
is activated by the pedal control (Fig. C, 18) (see
paragraph 7.3.2).
Fig. 7: After following the first start-up procedure (see
paragraph 6.5) correctly, push the button (3) and place it
in the ON position. The green LED (8) confirms that the
machine is ON.
7.3.1 SELECTING THE H COMMAND
Fig. 8: Push the selector (6) and place it in the H position.
Use the regulator (2) to set tool rotation speed (see par.
7.3.3.).
7.3.2 SELECTING THE F COMMAND
Fig. 9: Push the selector (6) and place it in the F position.
To activate the tool (Fig. B, 11), keep the pedal control
pushed (Fig. C, 18). Choose the tool rotation speed (Fig.
B, 11) by rotating the speed regulation knob (2) on the
control unit (see par. 7.3.3).
Fig. 10: To stop the tool (Fig. B, 11) lift the foot from the
control pedal (18). The pedal control is not active when
the green LED (1) is off (see fig. 7).
7.3.3 TOOL ROTATION SPEED
Fig. 11: Tool (Fig. B, 11) rotation speed is set by using the
corresponding knob (2). Tool (Fig. B, 11) rotation speed
increases in proportion as the knob is turned clockwise to
a maximum of 35,000 rpm.
Fig. 12: When the knob (2) is turned fully anticlockwise
(Min.), the tool (Fig. B, 11) is stationary.
If the green LED (Fig. A, 1) is on, the tool is
stationary but not off.
7.3.4 SELECTING TOOL ROTATION DIRECTION
Fig. 13: Tool rotation direction can be selected using the
button (4).
Fig. 14: When the button (4) is in the Fwd position the
tool rotates clockwise.
Fig. 15: When the button (4) is in the Rev position the tool
rotates anticlockwise.
ARIO 35
Tool rotation direction can also be changed by
pressing button 4 during operation. The tool will
slow down completely and automatically change
the direction of rotation. The choice of direction
of rotation facilitates use of the micromotor by
left-handed operators.
Fig. 16: Proceed to machine the element.
While machining, you are recommended to wear
protective gloves and goggles (see par. 2.4).
Fig. 17: When pausing during machining:
1. Push the button (3) and place it in the OFF position and
make sure the green LED (1) is off;
2. rest the handpiece on the stand with the point facing
outwards (Fig. B, 15).

RESIDUAL RISKS
A residual risk is:
• a risk which cannot be totally reduced through design
and protection techniques;
• a potential but non-describable risk.
The residual risks associated with the ARIO 35 laboratory
micromotor can include situations such as those
described below:
• accidental contact with the tip of the moving tool,
without the protection of gloves for example, could
cause wounds, abrasions or burns;
• accidental contact with splinters of material or
machining waste without the protection of goggles
could cause eye injury;
• work inside the machine performed by unauthorised
persons or with the machine plugged into the mains
power supply.
To avoid accidents, always respect the contents of
this manual while working.
In the event of doubt of any kind, always contact
the manufacturer or an Authorised Service
Centre.
8.1
CLEANING THE EQUIPMENT
Use a dry cloth to clean the equipment exterior. If
necessary, dampen the cloth with a small amount of
water or a non-degreasing detergent (see paragraph 2.4).
The operator must ensure that the equipment is kept
clean and free from any foreign bodies such as debris,
water, non-conducting liquids etc. For this purpose
cleaning must be performed at the end of every shift,
with the equipment in stable conditions.
Before cleaning the outside of the equipment,
always make sure that the master switch is off. It
is prohibited to clean the equipment when it is
connected to the electric power supply mains.
The reference figures can be found on pages , 4, 5 and 6 of this manual.
