Safety circuit

The machine has a safety circuit that triggers whenever the
driver gets off the seat while the blades are engaged. The
safety circuit is also tripped when the parking brake has not
been applied and the driver rises from the seat.
Drive to the blades is stopped when the safety circuit is
tripped. There is a short delay to prevent stopping if the driver
bounces on the seat.
• When the safety circuit has stopped the drive to the
cutting unit, the control must be pushed and pulled out
again to start the blades. Drive to the blades can be
started only when the driver is sitting on the seat.
3
• Push in the lever to disengage the blades.
• Pull out the lever to engage the drive of the blades.
Safety circuit check
• Check daily to ensure that the safety system works by
attempting to start the engine when one of the conditions
above is not met. Change the conditions and try again.
