Operation
3.18 Connections for auxiliary hydraulics
Connections A and B of the auxiliary hydraulics are both pressure and return lines. Both
connections can be connected depending on how the pedal for the auxiliary hydraulics is
to be controlled.
Notice!
Follow the instructions in the Operator’s Manual of the attachment manufacturer
for connecting the auxiliary hydraulics to attachments.
3.19 3rd control circuit (option)
Danger!
In systems with a high output, the hydraulic oil is under a very high pressure –
Injury hazard!
☞
Check all hydraulic fittings before and after working with an attachment
☞
Check hydraulic hoses and lines for leaks, cracks, cuts, dents and narrowings
The High Flow (option) connections are assigned as follows:
•
A - pressure line/reservoir line (depending on switch position)
• B - reservoir line/reservoir line (depending on switch position)
• C – leak oil line
Operating the 3rd control circuit:
☞
Install an attachment on the quickhitch
☞
Before working with the attachment:
☞
Start the engine
☞
Lower the safety bars
☞
Switch in neutral center position – no oil flow to A
☞
Switch to the left, oil flow to A (home position)
☞
Switch to the right, oil flow to B (switch position). When it is released, the switch
returns to neutral position for a brief inversion of the oil flow!
➥
The oil flows through the connection that is actuated.
☞
After working with the attachment:
☞
Press switch D to neutral position.
➥
The oil flow is stopped.
☞
