5.3 Mains connection

Mains connection and any extension
cords used must comply with

Connections and repairs to the
electrical equipment may only be
carried out by qualified electricians.

5.4 Dust connection

The unit must be connected to a
suitable dust collector.
Flexible hoses must be of "non-

connected to the machine ground
system.

5.5 Starting operation

You can start the machine with the
green ON-button.
The red OFF-button on the main
switch stops the machine.
The proper belt tracking must be
observed (in case of adjustment
need, see chapter 7.5).
6. Machine operation
The belt and wheel grinder is
designed for grinding metal materials
only without use of water.
Hold and guide the workpiece safely
during machining.
Do not perform any operation
freehand; always have the workpiece
supported by the tool rest and/or to
the working table.
Apply a moderate pressure on the
workpiece and keep it moving for
smooth grinding.
Pressing too hard overheats the
motor and prematurely wears down
the abrasives.
Keep a tray filled with water and dip
your workpiece regularly to prevent
overheating.
Overheating can weaken metals.
When the wheel becomes loaded of
debris, use an approved grinding
wheel dresser and dress the wheel.
Tool sharpening:
Note the original bevel angle on the
item to be sharpened and try to
maintain the same shape.
The grinding wheel should rotate into
the object being sharpened.
Grinding arm tilt:
Loosen the screw (N, Fig 9) and tilt
the grinding arm as desired.
