5. Once the grinding or cutting
is finished, pull in and release
the on/off switch (1) to stop the
grinder.
WARNING.
Avoid flying sparks
and ensure they do not hit any
inflammable materials, as they are
very hot and could cause personal
injury or a fire.
WARNING.
The disc continues to turn for a few seconds even
though the switch is turned off. Keep your hands well away from
the moving disc.
Led overload protection system
Overloading the tool means the tool is being leaned on
excessively during use, slowing down the speed of the tool. As a
result of the motor slowing down, the internal fan does not work
to its full capacity.
1. The LED Overload protection system will alert you when it is
overloading.
2. The grinder will warn you when
you are approaching overload by
flashing the Yellow light
3. If you continue to ignore the
yellow light or do not see it, the
red light will come on and the
grinder will immediately come to
a stop.
4. When this occurs, wait a brief moment then restart the
grinder, however, take additional care not to press on the tool
too much.

Variable speed

The variable speed feature of this grinder enhances the grinding
performance and saves the disc from undue wear.
1. The variable speed dial (13) is used to program the speed of
the disc. The speed should be adapted to the material being
grinded.
30º
15º
9
2. Use your finger or thumb to turn
the dial forwards to increase
the speed and backwards to
decrease it.
3. Position "1" denotes the lowest
speed. Position "6" denotes the
highest speed.
NOTE.
Using the correct speed for
the job increases the life of the disc.

Variable speed with soft start

This grinder is fitted with soft start technology. This feature
operates when you start the tool by slowly increasing the power
to the selected speed. The soft start feature eliminates any "kick"
when the grinder is switched on. In conventional grinders without
soft start the switch is heated up instantly thus reducing the life
expectancy. The soft start feature ensures a longer life for the
tool.

Replacing a disc

CAUTION.
Switch off the grinder and disconnect it from the
power point.
1. Turn the angle grinder on to its back and press the spindle
lock button (3) and rotate the spindle until it locks.
2. Insert the pins of the wrench (9) into the holes in the outer
flange (10) and remove it and the old disc.
NOTE.
Do not remove the inner flange (12).
