	Operating the attachments

NOTE

The attachment variable pump will attempt to maintain the oil flow rate specified by the attachment plug and potentiometer, even if the engine RPM drops.

Only when the maximum swash angle of the pump is reached will the oil flow be reduced when the RPM are reduced (refer to diagram).

ATTENTION

When the attachment is no longer in use, al- ways turn the pump off with the safety switch so that the hydraulic oil will not heat up un- necessarily.

Switching off the attachment variable pump

-Turn the safety switch (6) off. The indicator in the switch will extinguish.

NOTE

When you stop the engine without switching off the attachment variable pump, the pump will not start after the engine is started again (for safety reasons).

To start the attachment variable pump, you must set the rotary knob (5) to 0 and the turn the safety switch (6) off and on once.
