WARNINGS SPECIFICALLY RELATED TO GRINDING AND ABRASIVE CUTTING
OPERATIONS
Use only the type of cutting/grinding wheels recommended for your tool and the
protection specifically designed for the selected cutting/grinding wheel.
Cutting/grinding wheels not designed to be used with the tool cannot be adequately
protected and are unsafe.
The protection must be solidly fixed to the tool and placed in the safest position
possible so as to minimise the potential risk of contact between the operator and
cutting/grinding wheel. The protection is designed to protect operators from the ejection of
fragments in case of breakage and from accidental contacts with the grinding wheel.
Cutting/grinding wheels must be used for the recommended applications only. For
example do not use the cutting side of the wheel for grinding operations. Abrasive
cutting wheels may break because they are designed to be used for peripheral grinding
operations and for the application of lateral forces.
Always use the cutting/grinding wheels with undamaged flanges and verify that their
shape and dimensions are appropriate for the selected cutting/grinding wheel. The
purpose of flanges is to support the cutting/grinding wheel and reduce the potential
risk of breakage.
Flanges for cutting wheels may be different from those of grinding wheels. Do not use
grinding/cutting wheels that have been fitted on larger tools. These cutting/grinding
wheels are unsuitable because of their higher speed as compared to that of smaller tools
and could therefore cause explosions.
Do not "stall" the cutting wheel or apply an excessive pressure. Do not attempt to
increase the cutting depth. The application of a high pressure on the cutting wheel
increases the load and the risk of torsion and bending during cutting, with the consequent
risk of rebound forces or breakage.
Do not stand in line with the cutting/grinding wheel or behind it while it is rotating.
When the cutting/grinding wheel moves away from the operator's body during operation,
the rebound force may push the revolving cutting/grinding wheel and the tool towards the
operator.
If the cutting/grinding wheel bends or the cutting operations stops for any reason,
disconnect the tool from the power supply and keep it still until the cutting/grinding
wheel has come to a full stop. Do not attempt to remove the cutting wheel while it is
moving because this could produce a rebound force. Identify the cause of the problem and
perform the necessary corrective actions to prevent the problem from reoccurring.
Do not resume the cutting operation. Resume the cutting operation only when the
cutting wheel has reached its maximum speed. The cutting wheel may stall, lift or
produce a rebound force if the tool is restarted when the work piece is present.
Always use appropriate supports for panels or large work pieces in order to minimise
the risk of interlocking and rebound forces. Large work pieces tend to bend because of
their weight. Supports must therefore be placed under the work piece, close to the cutting
line and to the edge of the work piece on both sides.
Pay particular attention when cutting "pockets" on existing walls or other areas with
limited visibility. The projecting cutting wheel may cut gas or water pipes, electrical cables
or other objects and thus produce a rebound force.
PARTS OF THE TOOL
1 - Identification plate
2 - Switch lever
3 - Switch block
4 - Spindle locking button (GM62N only)
5 - Spindle
6 - Auxiliary handle
7 - Adjustable guard
8 - Collar for fixing for the protective
9 - Spacer
10 - Locking ring
11 - Motor ventilation slots
12 - Wrenches
STARTING UP
Before starting-up the tool, ensure that:
- the packaging is complete and does not show signs of having been damaged during sto-
rage or transport;
- the tool is complete; check that the number and type of components comply with that re-
ported in this instruction booklet;
- the power supply and socket outlet can support the load reported in the table and that in-
dicated on the tool identification plate reproduced and explained on page 11.
ASSEMBLING THE TOOL
- Screw the auxiliary handle (6) in one of the holes on the gearbox, the handle can be
mounted on the left or right of the tool body.
- fit the guard on the body of the tool using the collar (8).
Lock it in position by tightening the screw.
The guard must be mounted level with the handle.
FITTING ABRASIVE WHEEL
1. Insert the spacer (9);
2. insert the abrasive wheel;
3. screw and tighten the lock nut (10) using the pin wrench, preventing the spindle form
moving using the 17 mm. spanner or the spindle locking button (GM62N only).
BEFORE STARTING THE TOOL
Ensure that:
- the power supply conforms with the characteristics of the tool;
- the power supply cable and plug are in perfect condition;
- the ON/OFF switch works properly though with the power supply disconnected;
- the spindle locking button (GM62N) (4) is released (rotate the abrasive wheel by hand for
at least one revolution);
- all the parts of the tool have been assembled in the proper manner and that there are no
signs of damage;
- the ventilation slots are not obstructed.
STARTING AND STOPPING
- Starting: push the switch block (3) forward towards the body of the machine and simulta-
neously push the switch lever (2) up (fig. 4) in order to lock the switch in operating position.
- Stopping: push the switch lever (2) up in order to release the switch block (3).
