Safety Instructions:
• Do not exceed max. operating speed of tool
and clamping element.
• Observe accurate mounting of tools. Run tool
a few seconds under no load. Replace
vibrating Wheels/discs at once. Protect
wheels from knocks and grease.
• Secure work, use clamps or vise to hold
work.
• The grinder operator shall wear working
gloves, safety goggles or face shield at all
times when the grinder is in operation.
• If noise level exceeds 85 dB(A) at the work
station, sound insulation and hearing
protection measures must be taken by the
operater.
• For additional personal protection, it is
advisable to connect tool to a ground fault
circuit interrupter, (only in damp areas).
For additional safety instructions
refer to enclosed brochure EW 39 210 01
Before start-up.

Operation conditions and instructions
This tool is equipped with an electronic
variable speed tachometer selector and an
overload cut-out switch, which operates as
follows:
1. Soft start
2. With increased work pressure more current
is drawn , which virtually holds speed at a
constant rpm.
3. If the motor is overloaded, the electronic
cuts off the power. In this event switch at once
to OFF position, restart right away to assure.
cooling effect in no load mode. Repeated
automatic cut off indicates, tool is being
overloaded.
Attention
: Even if the cut-out is not activated,
danger of overloading always exists, thus
don’t force the tool in order not to increase
unnecessarily excessive current draw, which
overheads the motor.
