(5) Cover the bucket cutting edge and teeth with the
bucket protector (5-3/arrow).
(6) Insert the plug of the bucket protector in the socket
(5-4/arrow).
(7) Disconnect the hydraulic hoses from the lifting
cylinders.
N O T E
- Have a sufficiently large oil pan ready to catch the
hydraulic oil that flows out.
- After towing has been completed, fill the lifting cylinders
with hydraulic oil and deaerate them by raising and
lowering the bucket arm several times.
(8) Using a suitable lifting device, e.g. a second loader
with an attached bucket, lift the bucket arm of the loader
to be towed until the mechanical bucket arm support can
be inserted at the loader to be towed (7-1).
(9) Mechanically prop up bucket arm [e.g. by inserting the
bucket arm support (option) (1-1/arrow)] and lower bucket
arm until it rests on the bucket arm support.
(10) Close the ball block valve (1-2/arrow) for the working
and auxiliary hydraulics.
(11) Block the swivel mechanism by inserting the blocking
wedge (1-3/arrow) in the swivel blocking mechanism (1-4/
arrow).
(12) Attach the towing rod to the loader to be towed
[(7-2/1 - towing forwards) or (7-5/1 - towing backwards)] and
to the towing vehicle.
CAUTION
If the loader does not have a forward ranging and towing
coupling, the loader must only be towed backwards.
(13) Switch the hydrostatic drive motor to free flow before
towing. For this purpose loosen the hexagon lock nuts.
Screw the pins at both high pressure relieve valves (7-3/
arrows - slow loader) or (7-4/arrows - fast loader) of the drive
pump until they are level to the hexagon lock nuts. After
that fasten the lock nuts again.
N O T E
After towing procedure loosen the hexagon lock nuts.
Screw the pins out of both high pressure relieve valves until
the pins stop. Fasten the lock nuts.
(14) If necessary, remove the chocks.
(15) Release the parking brake (4-7/14).
