12.4 Adjusting dispenser arm rotation speed
From the tractor cab, engage the tractor hydraulics
and operate the arm rotation in manual mode.
Check the speed of the arm rotation. The correct
speed is 30 rpm. If higher, see below for details to
achieve the correct speed:
1. Turn off the tractor before making any
adjustments on the machine.
2. Using a 13 mm spanner, unscrew all of the
bolts that hold the valve guard as shown.
3. The third from right valve section operates
the dispenser arm, and the lower setting
screw sets the flow/speed of the arm. Using
a 10 mm spanner, loosen the sealing/
locking nut as shown.
4. Using a 3 mm Allen key, turn clockwise to
reduce the speed. In practice the
adjustment required is very small, usually
max 1/4 turn clockwise. Tighten the locking
nut. Re-check the arm speed.Repeat until
the correct arm speed of 30 rpm is
achieved.
5. Replace the valve cover.
WARNING: Before working on this machine
Always ensure that the tractor is stopped, the hand brake is applied and
the ignition key is removed.
WARNING: Maximum speed
The dispenser must never be operated above a maximum of 30 rpm.
