WARNING!
If you bypass, remove or override a safety device in any other way, you are endangering
yourself and other persons working with the surface grinding machine. The possible
consequences include:
injuries due to tools, workpieces or fragments hereof which are flying off at high
speed,
contact with rotating or moving parts,
fatal electrocution,
pulling-in of clothes.
WARNING!
Although the isolating safety devices provided and delivered with the machine are
designed to reduce the risks of coolants, workpieces being ejected or parts of tools,
breaking off grinding wheel or workpieces breaking off, they cannot eliminate these
risks completely. Always work carefully and observe the limit values of the grinding
process.
The surface grinding machine features the following safety devices:
a lockable master switch,
an emergency stop button,
a protective cover on the grinding wheel
1.9.1
Lockable master switch
In the "0" position, the lockable master switch can be secured against accidental or non-author-
ised switching on by means of a padlock.
The power supply is interrupted by switching off the master switch.
Except for the areas marked by the pictogram in the margin. In these areas there might be volt-
age, even if the master switch is switched-off.
WARNING!
Dangerous voltage even if the master switch is switched off.
The areas marked by the pictogram might contain live parts, even if the master switch is
switched off.
1.9.2
Emergency stop button
CAUTION!
Only press the emergency-stop button in a genuine emergency. You may not use the
emergency stop button to stop the machine during normal operation. The life time of the
emergency stop button is not designed for operational shut-down of the machine.
Use the master switch.
The emergency stop switch is used to stop the drive of the grinding wheel in an
emergency. The drive with grinding wheel will continue to run for a while, depending on the
mass moment of inertia of the grinding wheel with flange and associated components.
After actuation, turn the knob of the switch to the right to be able to restart the drive of the grind-
ing wheel.
