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.
