ATTENTION: The arrows indicating the rotation
direction on the driving machine gearbox and on
the operating tool must coincide.
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.
The machine features 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 ma-
chine becomes disabled. Тo 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.
The rotation speed can be varied smoothly from
position A to G by turning electronic regulator 8,
placed on the rear of the motor cover.

Stabilising the speed
The electronic device stabilises the pre-selected
speed (rpm) constantly in order to limit the spin-
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-
8
EN
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.

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.

CLEANING
3600
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.
