INITIAL RUN
A. Check that the motor hoses are connected together.
B. Run tractor engine at idle speed and engage PTO drive.
C. Increase PTO speed gradually up to 360 rev/min.
D. The pump will start operating during run-up. Flexing of the motor hoses and turbulence of the oil
tank can be observed.
E. When pump is operating run system at 360 rev/min PTO speed for 10 minutes.
F. Check oil level. The oil level is correct when visible in the bottom of the filler assembly strainer.
BLEEDING RAMS
The ram cylinders at first will be full of air, therefore it may take some time for the cylinders to move after
the control levers have been operated. Ensure sufficient space is available to allow for any unexpected
movement of the arms.
Bleeding the First Ram
Due to the fact that the first arm can move past the vertical (overcenter) when fully raised, a restrictor
may be fitted in the first ram hydraulic system to give a slow, controlled movement of the arm past
center. It is essential that the first ram is fully bled to prevent fall back to the arm when the arms are
stretched out and taken past vertical.
NOTE
: The following instructions must be carried out before any attempt is made to raise more than one
arm at a time.
A. Engage PTO drive with tractor engine at idle speed.
B. Increase PTO speed to 360-400 rev/min.
C. Fully retract second cylinder.
D. Fully retract the first cylinder.
E. Slacken hose connection at the bottom of the first cylinder.
G. Continue the bleeding until only clean, bubble-free oil is escaping from the fitting. Tighten fitting.
H. Open and close all cylinders to expel the air.
I. Check the oil level in the tank/tractor hydraulic oil reservoir and top up if necessary.
J. Check all hydraulic connections in the cylinder circuit for tightness.
Do not raise more than one arm at a time until cylinders are completely free of air. Unex-
pected movement of the arms can be dangerous.
