Quick Start Operators Guide
500 & 730 Star-Cut

Height of Cut
Height of cut is controlled by
varying the amount of ram stops
down over the ram rod.
Start with 6 ram stops on all rams.
Cutting height can be in- or
decreased by adding or reducing
the amount of stops.
Attention. Each ram must have
equal amount of stops
Fine adjustment and balance of
cut between the rotors is achieved
by adjusting the length of the base
screw attached to the ram.
Option. Its possible to buy
"Stopclips" for faster
fineadjustment in the field.
Sparepart No. 7051005

Transport
Both centre axle rams
must have all the stops
down.
Both wing axle rams
must have all the stops
out.
When the stops are in the
correct position lower the
machine and keep
pressurizing the rams until
both the wings rams are
fully closed to give a safe
and narrow transport.
Mount safety strap.

Hose Connections
Wings; red banded hose,
single acting spool c/w dump
Wheel axle; blue and yellow banded
hose, double acting spool c/w dump

Hitching to the Tractor
Low drawbar
When attached to the low
drawbar of the tractor always
use the parallel linkage bar
attached to the lower hole on
the hitch plate.
High drawbar
When using the high drawbar
it may not be possible to use
the parallel linkage, as when
the machine is full raised the
PTO shaft may hit the hitch.
We recommend that the
parallel linkage bar is
removed and the hitch is
locked by replacing the pin in
the middle hole.

Leveling the Machine
When the machine is fitted to
the tractor and set at working
height, the front of the skid
should be in same height as
at the rear of the skid.
To raise the front of the skid
shorten the adjustable link
that is attached to the rear
axle.
To lower the front of the skid,
lengthen the adjustable link.
Adjusting the link is made
much easier by dropping the
stands and then gently lower
the machine until the weight
is off the hitch

Driveline – clutch-adjustment. Bondioli
1. Check the condition of the friction discs before use and following periods
of storage. Release the tension from the spring, turn the clutch while
holding the P.T.O stationary. Or slip it using the tractor for it. (On 730, first
slip the outer clutch, then the inner). Adjust the spring compression to the
original setting.
2. Following seasonal use, unload the spring tension and store clutch
assembly in a dry place. Check condition of friction linings and reset
spring compression to original height before use.
3. Before season. See issue 1.
4. Should the assembly overheat due to frequent or prolonged clutch
slipping, dismantle for inspection.
The original thickness of the lining is 3.2 mm, replace them when worn to 2.5mm
or when overheated. Clean up all contact surfaces and replace any damaged
components before assembly.
