SPREADING
MATERIALPERFORMANCE
Once you have spread the first part of the bale. We
recommend stopping the crossbeater before crowding
up the Telehawk to allow the next part of the bale to fall
onto the bed chain. Once the straw has fallen onto the bed
chain. The machine can be levelled out and the crossbeater
and bed chain re-started.
If spreading wet or poor quality bales it may be an
advantage to stop both the crossbeater and bed chain
before inclining the machine.
Do not force bales against the crossbeater by inclining the
body steeply while spreading. This may cause a blockage
and could also damage the machine.
If you are moving from one shed to another. We suggest
stopping the bed chain by turning the speed to zero and
then stopping the crossbeater. Before starting again, make
sure the fan is running at normal speed then re-engage the
crossbeater. The bed chain speed can then be increased.
The length of material will vary with the condition of
the bale. Fresh clean straw will tend to result in a longer
material whereas old, slightly damp, weathered or matted
bales will tend to have a shorter length. The power
consumption will also vary with the material being spread.
In general damp or matted straw will require a relatively
high power input.

REVERSE TIME
Generally, the taller the bale in the chamber, the longer the
reverse time of the bed chain is required. The reverse time
can be increased by pressing the increasing reverse time
button and decreased using the decreasing button.

PRESSURE SWITCH
The machine is fitted with a pressure sensing system
to prevent the fan being overloaded. This works
automatically by briefly reversing the crossbeater and
bed chain, this is called the reversing time. The reversing
time can be altered on the control box in the cab. The
pressure sensor setting can be altered on the side of the
machine. The factory setting is 100 bar (1450psi).
The pressure at which the bed chain reverse movement
is triggered can be varied by rotating the knob on the
outside of the rotor housing. We recommend a starting
setting of 100bar. The higher oil flow rate the higher
the pressure setting. With a higher oil flow loader the
fan is rotating at a higher speed, hence the fan can
spread more straw. With a lower oil flow loader the fan
is rotating slower, hence can be more easily blocked. To
avoid this the pressure switch needs to be set lower.
If the pressure switch is set too high you can easily block
the fan. If the pressure switch is too low the machine
will keep going into automatic reverse and take a long
time to spread the bale (bleed the pressure switch if the
machine goes into reverse at random times).
