fixed firmly.

er symptoms not typical for operation, stop the

If you cannot detect the reason yourself - contact
the nearest authorised SPARKY service centre.
Operating with a faulty machine may cause an
accident!

sure to the processed surface by rearing down
on the machine but move the machine smooth-
ly.

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.
WARNING: Never use alcohol, petrol
or other cleaning agent. Never use caustic
agents to clean plastic parts.
WARNING: Water must never come
into contact with the tool.
IMPORTANT! To assure product safety and re-
liability, repairs, maintenance and adjustment
(including brush inspection and replacement)
should be performed by certified service centres
or other qualified service organisations, always
using genuine replacement parts.
