RUNNING UP PROCEDURE
PA92 Ti
1. Ensure that the rotor control is in “STOP” position, start the tractor, engage PTO and allow the oil to
circulate for about 5 minutes before operating the arms.
2. Operate the armhead levers through their complete range ensuring that all movements are functioning
correctly.
3. Check that the flail nuts and bolts are tight. Place the flail head at a safe position and move the rotor control
to “ON” position. After initial fluctuation due to priming, the rotor should settle to a steady speed. Increase
PTO speed to approximately 360 RPM and run for a further five minutes before engaging and stopping
tractor.
4. Check the hose runs and observe that they are free from any pinching, chafing, straining or kinks. Recheck
the oil level in the tank and top up as necessary.

1. Ensure PTO lever is in neutral position, and isolate tractor hydraulic linkage. Start the tractor and select
external service supply on the hydraulic controls. Allow the tractor to run for several minutes before
attempting to operate any of the machine control levers.
2. While operating, move the levers through their complete range ensuring that all movements are
functioning correctly.
3. Check the tractor rear axle oil level and top up if necessary.
4. Place the flail head at a safe position and bring tractor engine revolutions to 1000 RPM to avoid stalling
when the starting load is placed on the motor. Engage PTO and allow the rotor to run for several minutes.
Do not leave the tractor cab or allow anyone to approach the flail head at this time.
Do not allow the pump to continue working if the rotor does not turn. Overheating and
serious pump damage to the pump can be caused in a very short time.
5. After running up the machine, increase PTO speed to approximately 360 RPM. Run machine further for
five minutes before disengaging the PTO and stopping tractor. The reason for this running period under a
no load condition is to thoroughly circulate the oil in the reservoir through the return line filter.
6. Check the hose runs and observe that they are free from any pinching, chafing, straining or kinks. Recheck
the oil level in the tank and top up as necessary.
