15 8-10m Press Range
Operating Instructions
When the Press is parked for
extended periods of time it should
ideally be left in the unfolded
position: ie; work position for
stability, safety and ease of access
for maintenance. However parking
the Press resting on its front jack
is acceptable in the normal course
of operation.
Tractor Oil Flow Adjust-
ment: As a general rule the trac-
tor oil flow rate should be set in
the lowest setting before starting.
This can then be increased to al-
low the desired rate of operation
as applicable. This will minimise
excessive oil flow and consequent
power usage and heat generation.
Do not open taps while tractor
hydraulics are in float.
The hoses in the lift circuit have
a maximum rated pressure of
415bar, and should be replaced
every 6 years. Other components
in this locking circuit have a ma-
ximum rated pressure of at least
350bar.
Hitching up machine when left
on parking stand
1. Back tractor up towards the front of
the drawbar. Attach the hydraulic hose
for the jack. If the jack has been left
with the machines weight resting on it
be sure not to have the tractor in float
when you open the in line tap. Doing
this will result in the machine dropping
suddenly. Adjust the height of the
drawbar eye to the level of the tractor
hitch.
2. Back up and fit tractor drawbar pin.
Lower the machine using the jack so
the weight is now on the tractor. With
the tractor now supporting the machine
place the jack spool in float, the jack
will then return to closed ready for
swinging into the transport position.
3. Remove the locking pin and swing the
jack round into the transport position.
Connect all other pipes and the light
cable.
4. The machine is now ready to transport.
Hitching up machine when left
in work position
1. Back the tractor up towards the front
of the drawbar. Attach the tilt ram
hydraulic hoses (red).
2. By operating the spool in the tractor
cab it is possible to lift the drawbar
from the ground up to the tractor hitch
height. Back the tractor up and fit the
tractor drawbar pin. Connect all other
hydraulic hoses and light cable.
3. If the machine has been left open
overnight it is advisable to tilt the
machine forward (as if it were to be
folded) and operate the wing circuit
cylinders to open and lock the wings
out to the set pressure. After doing that
tilt the machine completely rearwards
onto the DD roll.
4. The press is now ready to be set for
work.
