MOUNTING THE WHEEL GUARD
Before performing the following operations,
switch the machine off and withdraw the plug
from the socket.
Mounting the wheel guard (fig. 1)
- Rotate the black plastic ring (Fig. 2), so
that the crevice S of the ring coincides with the
groove for the tooth of the fixing lever L.
- Place the wheel guard in non-operating po-
sition (Fig.2) so that the four teeth coincide with
the four grooves in the bearing seat (Fig.3).
- Press the wheel guard down and rotate it
clockwise to the necessary operating position
where the wheel guard is fixed by lever L.
Rotating the wheel guard in a new operating
position
- Rotate the wheel guard clockwise only
to the necessary operating position where the
wheel guard is fixed by lever L (Fig.4).
Removing the wheel guard
- Rotate the wheel guard in non-operating
position (Fig.3) so that the four teeth coincide
with the four grooves in the bearing seat, and
then draw it upwards (Fig.2).

AUxILIARY HANDLE

Normally auxiliary handle 6 is screwed on the
machine left side. It can be mounted also on the
machine right side if this is more convenient for
the operator.
TURNING THE MACHINE CASE
The machine case can be turned to 90° or to
180°. The first way of mounting is implemented
when the machine is used mainly for cutting,
and the second - in case the operator works bet-
ter with his left hand. In both cases the case
turning must be carried out in a specialised serv-
ice centres for SPARKY power tools.
RECOMMENDATIONS
When cutting, do not apply pressure, do not os-
cillate the wheel. Work with moderate feed rate,
suited to the material to be machined.
The direction of cutting is very significant. The
machine must always be fed against the direc-
tion of wheel rotation. Otherwise, danger exists
for the wheel to be forced uncontrolled out of
the cut.
When cutting profiles or rectangular pipes it is
best to start with the smallest cross section.
When grinding do not apply pressure to the
processed surface by rearing down on the ma-

chine but move the wheel regularly backwards
and forwards. Special wheels shall be used for
processing non-ferrous metals. Best results
when roughing can be achieved with the wheel
inclined at 30
Never use cutting wheels for roughing opera-
tions. Usage of wheels thicker than 6 mm is not
recommended.

Maintenance

WARNING: Always ensure that the
tool is switched off and unplugged before
attempting to perform inspection or mainte-
nance.
BRUSH REPLACEMENT
When the carbon brushes are worn out, the
machine switches itself off. In this case both
brushes must be replaced simultaneously with
genuine brushes at SPARKY service centre for
warranty and post-warranty service.
GENERAL INSPECTION
Regularly inspect all fasteners and ensure they
are properly tightened. Should any of the screws
be loose, retighten it immediately to avoid haz-
ards.
If the replacement of the supply cord is neces-
sary, this has to be done by the manufacturer or
his agent in order to avoid a safety hazard.
CLEANING
For safe operation always keep the machine
and its ventilation slots clean.
Regularly check to see if any dust or foreign mat-
ter has entered the ventilation slots and the grills
around the switches. Use a soft brush and/or air
jet to remove any accumulated dust. Wear safety
glasses to protect your eyes whilst cleaning.
Exterior plastic parts may be cleaned with a
damp cloth and mild detergent if necessary.
When operating in heavily dusty environment
(cutting stone) the ventilation slots and the
switch slider of the machine running at no load
must be obligatory cleaned after
(every 8 h operation) by compressed air or by
gently tapping it near the ventilation slots with
non-metal object (Fig.6a,6b).
