2. Description

2.1 Electronic regulation and control
2.1.1 Starting current regulator
The current drawn by the tool at the moment it is switched on is many times that of
its rated current input. The starting current regulator reduces this starting current
greatly, thus preventing the electric power supply fuse from tripping. It also ensure
that the tool starts smoothly, without a jolt.
2.1.2 Constant-speed electronics
The constant-speed electronics maintain spindle speed at an almost constant level
during idling and while running under load. This constant speed of rotation ensures
optimum material removal performance.
2.2 Motor protection
2.2.1 Temperature-dependent motor protection
The temperature-dependent motor protection system monitors current input and
motor temperature, thus preventing damage to the tool caused by overheating.
Should the tool overheat during use, the motor then cuts out and can be restarted
only when the pressure applied to the disc is reduced.
The permissible load on the tool is not a fixed value, but depends on motor temper-
ature.
In the event of the motor cutting out due to overheating, the pressure on the disc must
be relieved and the tool allowed to run under no load for approx 30 seconds.
