Starting under cold conditions (machine powered by a tractor)
When starting the machine in severe frost, allow it first to idle at low speed for about 5
minutes; this warms up the oil.
Warming up the oil reduces wear on the hydraulic system significantly and prevents
damage.
3.7
Electric drive, start and emergency stop.
The output of the motor is 15 kW and its speed is 1,480 rpm.
The machine is equipped with an automatic Y-D starter with an emergency stop fea-
ture.
All the electric installations have been made ready.
The cross-section of the extension cord required for a tension of 400 V must be 6 mm2.
When starting up the machine, check that the direction of rotation corresponds to the
arrow on the blade cover.
To check the direction of rotation, run the motor for a short while and then stop it sud-
denly.
The direction of rotation is reversed using the phase-switch in the appliance inlet.
The machine may only be connected to a power supply equipped with a fault current
switch of 30 mA.
The machine must be equipped with a 5-pole extension cord (L1, L2, L3, N ja PE) to
operate.
NOTE !
Electric work may only be carried out by a professional person.

Starting the electric motor using the Y/D starter, Fig. 8
Press the start button A. In the Y-position the motor starts rotating at slow speed with
low output. The start phase takes several tens of seconds.
As the engine speed increases, the D-position is automatically switched on and the
motor quickly reaches full speed.
At the same time, the signal light B between the pushbottons illuminates.
Stop the engine using the pushbutton C.
