Pump & Motor Failure Prevention
•
Never run out of oil.
•
Never run a cold machine straight up to speed, first ensure engine
revolutions are low then engage/disengage the head motor.
•
Never increase or decrease engine speed quickly.
•
Never stop or start rotor at high engine speed.
•
Never transport with P.T.O. in gear.
•
Regularly check condition of suction line hose.
•
Never operate above recommended P.T.O. speed.
•
Check that pump fittings are tight.
•
If any strange noise occurs from the hydraulics, stop immediately and
investigate.
•
Remember, pump and motor warranty is limited to replacement due to
faulty materials or manufacturer. Cavitations and peak pressures are
very easily detected on pump inspection.
•
Warranty will not be considered if fault is due to misuse.
•
Never cause severe sudden movements to arms. Pressure will peak
and will transmit back to pump, resulting in failure.
