Maintenance - SPARKY HD PROFESSIONAL M 750 HD Instrucciones De Uso

- Release the fastening lever L to a stable
position in which the wheel guard is fixed (the
fixing lever tooth enters into one of the guard
grooves).
Removing the wheel guard
- Press the fastening lever L (Fig.3) to re-
lease it.
- Rotate the wheel guard in non-operating
position (Fig.2a) so that the four teeth coin-
cide with the four grooves in the bearing seat
(Fig.2b).
- Remove the wheel guard.
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. The auxiliary handle for these
models is connected to the body of the machine
through vibration dampers, protecting the op-
erator and reducing fatigue.
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 to 40 to the processed surface
0 0
Never use cutting wheels for roughing opera-
tions. Usage of wheels thicker than 6 mm is not
recommended.
Original instructions
For heavy and continuous operation use power
tools equipped with electronics for overload pro-
tection (models with index CES or Plus).

Maintenance

WARNING: Always ensure that the
tool is switched off and unplugged before
attempting to perform inspection or mainte-
nance.
BRUSH REPLACEMENT
This power tool is equipped with auto-stop
brushes. 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).
WARNING: Never use alcohol, petrol
or other cleaning agent. Never use caustic
agents to clean plastic parts.
