NE
To install the Bench grindin
g machine, proceed as follows:
Clean the Machine
Before starting assembly, clean the protective product from the machine's components.
4.1
Positioning and fixing on the bench
Loss of Stability
Mount the Bench grinding machine on a surface that is sol
id and strong to avoid it falling over
and so it does not cause vibrations;
Clean the Workbench
Before fixing the machine in place, clean the workbench of any materials and dirt that may be
present.
Place the machine on a workbench (or other support
ing surface) that is level, stable and
sturdy and secure it with four bolts in the appropriate fastening holes in the base of the
machine body (see
Figure
1
).

CONTROL SWITCHES
They are located on the base of the machine body. They are used to turn the bench grinding
machine on and off.
6.1
On switch (start)
The green button (I), is used for starting (turnin
g on) the
bench grinding machine (
Figure
7
). With this button, the
electric motor is powered and the equipment is set in
rotation (grinding wheel, brush, etc.).

.
6.2
Off switch (stop)
The red button (0), is used for switching off (stop) the bench grinding
machine (
Figure
8
). With this button, the power to the electric motor
is turned off and the rotation of the equipment is stopped
(grin
ding wheel, brush, etc.).

OPERATION
7.1
Instructions for Use
Bench grinding machines are very easy to use.
The
dry grinding wheel
is used for grinding, sanding and/or smoothing solid and massive
material (especially metal and metal alloys) by abrasion.
The
belt grinding wheel
is used for grinding, sanding and/or smoothing solid and massive
material (especially metal and metal alloys) by abrasion.
Use of the machine
The Bench grinding machine must be used only with tools that are suitable for the type of
machine and the typ
e of material to be processed.
Risk of Abrasion and Accident

Before using the machine, make sure that it is rigidly fixed to the workbench to prevent
movement or loss of stability.

Wear appropriate personal protective equipment (PPE) such as gloves, g
oggles, overalls or
apron and safety shoes.
It is recommended to not extend the continued use of the machine for more than 10 minutes
to avoid overheating of the machine (which could damage the engine) and the equipment.

MACHINE SA
FETY
8.1
Electrical Safety
The control device inserted in the electrical circuit of the Bench grinding machine is a
magnetic switch
with two buttons (see Section 6 of this manual). This prevents the danger
of unwanted and/or accidental starts of the machine, s
ince the switch can only be activated
through a voluntary action suitable for the given purpose and when the machine is powered.
The start button is, moreover, equipped with a protective ring.
The machine is also equipped with an
emergency stop button
, fo
rmed by a plastic cap
placed over the on and off switches, when pressure is applied it acts only on the stop button.
When, in an emergency, pressure is applied to the cap, the dangerous functions stop.
In the event of malfunction or breakdown, the Bench g
rinding machine is equipped with a
power cable and plug with
grounding conductor
, which provides a path of least resistance
for electric current and reduces the risk of electric shock.
The plug must be plugged into an appropriate outlet, grounded in accor
dance with current
regulation.
Extension cables must be of a section equal to or greater than the power cable of
the machine.
Electric Shock
Improper connection of the machine’s grounding conductor can result in the risk of electric
shock.
It is nece
ssary to connect the machine to a system equipped with a device for the automatic
disconnection of power in the event of a ground fault.
Check with a qualified electrician if you don't understand the instructions for
grounding or if you have any doubts a
bout the grounding of the machine.
