INSTA
LLING THE MACHINE
To install the Bench grinding 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 B
ench grinding machine on a surface that is solid 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.
Plac
e the machine on a workbench (or other supporting 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
).
Figure

-
up of fastening holes.
In the case of using a steel bench, it is advisable to place between the grinder and the
supporting surface a layer of material which is suitable to reduce the vibratio
ns.
Installing the Machine
Do not install the machine outdoors to avoid deformation, loss of function and damage to the
electrical control circuit.

).
Place the protective screen so that it does not touch the wheel and there is a maximum
gap (light) of
5 mm
between the metal support of the screen itself
and the wheel (see
the screen in
Figure
2
).

–
Mounting and adjustment of the protective screen.
2.
Fit the clamping brackets to the lower end of the p
rotective dry grinding wheel casing,
using the special screws with knob (see
Figure
3
). Place the clamping bracket so that it
does not touch the wheel and there is a maximum gap (light) of 2 mm between the
bracket
itself and the wheel.

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 (turning 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.).
Figure
7
–
Start button.
6.2
Off sw
itch (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 (
grinding wheel, brush,
etc.).
Figure
8
–
Stop button.
Risk of Abrasion

After pressing the off switch (0), the equipment will continue to rotate by inertia.


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
metallic brush
is used to clean away impurities and polish the outer surfaces of solid
and
resistant items.
Machine operation
The Bench grinding machine must be used only with sharpening wheels and brushes that are
suitable for the type of machine and the type 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, goggles, overalls or
apron and safety shoes.
It is recommended to not extend the c
ontinued use of the machine for more than 10 minutes
to avoid overheating of the machine (which could damage the engine) and the equipment.
