Preparing for operation
Working depth
Set the working depth first of all by way of the front raking wheel, be-
cause this will affect the pitch of the rear raking wheel.
Before setting:
•
Fix the stabiliser [+] in the upper position
•
Lower the implement complete with control device
•
Measure the working depth relative to the ground (basic setting: 10
mm to the front raking wheel, 20 mm to the rear raking wheel)
Adjust the working depth as follows:
> Lift out the implement complete with control device
> Switch off and secure the tractor
Close the ball valve
Close the ball valve before setting. If the ball valve is open and there
is an operating error, the implement can lower itself and cause serious
injuries.
> Close the stop valve on the hydraulic coupling for lifting and lo-
wering
> Unlock the adjusting nut under the chassis by means of the catch
and set the working depth by means of the adjusting nut
N
OTE
Two turns of the adjusting nut represent roughly 15 mm in height of the
raking wheel tines
Adjusting nut with spanner size 65
> After adjusting secure the adjusting nut by means of the catch
against twisting
> Lower the implement
> Switch off and secure the tractor
> Check the tine spacing and readjust it as necessary
You can now set the working depth on the rear raking wheel in the sa-
me way.
