HEAD CONTROL LEVER MICROSWITCH

The grip of the manual head control lever incorporates a microswitch for manual

control of the blade motor.

Microswitch

Operating lever

The microswitch is enabled when the machine is not in emergency state. In

compliance with the relevant existing standards, voltage is 24V and the

microswitch is installed in a housing (blue knob) sealed against external agents

such as dust or moisture, with a protection rating of IP 55.
