Running Up Procedure; Emergency Stopping - McConnel PA7070T Operator's Manual

RUNNING UP PROCEDURE

Before initial use of a new machine, all lubrication points must be greased and the gearbox
and oil tank levels checked and where required topped up before attempting to use the
machine. Refer to maintenance section for details.
Initial 'Running Up'
Ensure that the rotor control valve is in "STOP" position, start tractor, engage PTO and
allow the oil to circulate through the return line filter for about 5 minutes without operation
of the armhead controls.
Operate the armhead controls through their complete range of movements ensuring that
all armhead movements function correctly.
Place the flail head at a safe attitude and move the rotor control to "START" position; after
initial fluctuation the rotor should settle to a steady speed.
Increase PTO speed to approximately 360RPM and run for a further five minutes before
disengaging PTO and stopping tractor.
Do not allow the pump to continue working if the rotor does not turn; overheating and serious
damage to the pump can be caused in a very short time.
Check the hose runs and observe that they are free from any pinching, chafing, straining
or kinks. Re-check the oil level in the tank and top up as necessary.

EMERGENCY STOPPING

In all emergency situations machine operation and functions must be stopped immediately;
Stop PTO operation using tractor controls, then immediately kill electrical power to the
machine using the OFF (Emergency Stop) switch on the machine's control unit.
When the Auto-Reset feature is active the machines arm set is capable of unintentional
movement even when the PTO is switched off and stationary. Always ensure that electrical
power to the machine is switched off using the Off (Emergency Stop) switch on the
machine's control unit in emergency situations and/or when the machine is not being
operated.
In certain conditions, and/or if the Auto-Reset feature is active, the arm sets on cable
operated machines possess the potential to move unintentionally, even when the PTO is
switched off and stationary, if the levers were to be accidentally operated. Care must be
adopted to avoid any movement of the levers when the machine is not being operated.
Ensure arm sets are lowered fully to the ground when the machine is parked up or not in
use.
