Function
Soft-Start:
The features allows the motor to ramp up to its operating speed which greatly reduces amper-
age spiking at start up. This will prolong the life of the motor.
Main switch:
Two modes can be selected with the main switch:
Man: The turbine starts immediately.
Auto: The turbine waits for an electric tool to be switched on at the socket.
Speed control:
Speed control has been integrated into the manual and automatic modes.
Settings on the switch range are possible from 45° to 135°.
Advantages:
- Optimum adjustment of the suction power to suit the application.
- Increase in the service life of the turbine
- Reduction in noise emission
- Energy savings
Automatic starter
Work with an electric tool (grinder, etc.) can be optimised by using the automatic starter. The
main switch is set to the “AUTO” position and the electric tool connected to the socket of the
cleaner.
The suction motor is switched off. When the electric tool is now switched on, the automatic
starter detects. The flow through the connected machine and switches the suction motor on.
When work with the electric tool is stopped, the suction motor switches off after a delay of
approx. 3 seconds. The cleaner now stays in the standby mode until the electric tool is
switched on again.
