Maintenance - SPARKY HD PROFESSIONAL SM 1236CES Plus Notice Originale

ELECTRONIC CONTROL
WARNING: Do not operate the ma-
chine if the electronic device is faulty, be-
cause this means operating at increased
speed (rpm). The event of fault can be identi-
fied by the lack of soft start or the impossibility
to adjust the speed.
Models SM 1236/1433CES Plus feature full-
wave tachoconstant electronics for:
- Soft start and restriction of the starting cur-
rent;
- Speed pre-selection and control and main-
taining constant rpm upon overloading accord-
ing Table 1;
- Brief overload protection (upon jamming the
wheel). To resume operation release the ON/
OFF switch and then press it again;
- Continuous overload protection (the thermal
protection switches the machine off to protect
the motor from inadmissible overheating). Upon
actuating the thermal protection the machine
becomes disabled. To resume operation release
the ON/OFF switch and then press it again.
- Non-self starting safety (NVR) after restoring
the mains supply. To resume operation release
the ON/OFF switch and then press it again.

dle speed reduction under variable load values.

Thermal protection
To protect the power tool from inadmissible ther-
mal overload (motor damage) during extended
operation at overload the machine is equipped
with thermal protection. The electronic device
switches off the machine before the tempera-
ture reaches the critical value and the machine
switches from operating to safety mode.
Under safety mode the motor rotates at lower
speed to enhance cooling but the machine can-
not be operated. After a period of 3-5 minutes
the machine cools down and can be operated
again. To resume operation first turn off and the
turn on the ON/OFF switch.

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
matter 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 clean-
ing.
Exterior plastic parts may be cleaned with a
damp cloth and mild detergent if necessary.
