Maintenance - SPARKY SM 1212CE Notice Originale

SANDING WALLS AND CEILINGS WITH
SANDPAPER OR ABRASIVE NET
The brush ring (12) is situated on the guard (11)
perimeter. The brush ring features two func-
tions:
- It is the brush ring that comes into contact with
the processed surface first. As a result the guard
becomes parallel to the surface even before the
operating tool contacts it. This ensures uniform
contact between the tool and the surface.
- The brush ring retains the dust generated
during operation which is subject to extraction
by the dust extraction system and the vacuum
cleaner.
In case the brush ring (12) is damaged, de-
formed or worn out it can not perform the func-
tions it is designed for and shall be replaced im-
mediately. You can purchase a brush ring (12) in
any SPARKY service centre.
Excessive pressure may result in spiral pattern
of scratches, concaves and roughness of the
processed surface. Moreover excessive pres-
sure will overload machine transmission and
probably cause damage of the flexible shaft.
The driving machine must be running constantly
while the sanding head is in contact with the
processed surface.
Move the sanding head with uniform speed over
the entire area of the processed surface. Exces-
sive slow motion and motion intermission of the
sanding head will cause uneven processing of
the surface, tool digging and presence of con-
caves and bumps.
SURfACE PROCESSING WITH DIA-
MOND DISC
The diamond disc is most often used for clean-
ing concrete or stone surfaces and wall revet-
ment (footing).
Apply only as much pressure as is required to
keep the diamond disc (21) in contact with the
processed surface.
Do not apply excessive pressure. Excessive
pressure does not increase efficiency. It is a
prerequisite for the power tool fault.
SURfACE PROCESSING WITH SAND-
ING PADS
The sanding pads for dry sanding (25) are most
often used to achieve a specific surface appear-
ance (cleaning, renovation, and gloss) of wall
revetment made of decorative stone slabs (mar-
ble, granite, limestone, etc.).
Original instructions
Apply only as much pressure as it is required
to keep the sanding pad (25) in contact with
the processed surface. Do not apply excessive
pressure. Excessive pressure does not increase
efficiency. It is a prerequisite for the power tool
fault. Excessive pressure may damage the proc-
essed surface.
RECOMMENDATIONS
When sanding do not apply pressure to the
processed surface by rearing down on the ma-
chine but move the machine smoothly.
VII - 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.
