Operating Instructions
5.7 Hydraulics
A low oil flow should be used, i.e.,
tractor tickover or low flow
selected.
The wing circuit is controlled by an
overcentre valve contained within
the manifold block which positively
locks oil flow until pressurised by
the tractor. System pressure can
be retained in the circuit even after
depressurisation of the tractor
quick release couplings.
Exercise extreme care when
checking the valve or circuits, and
under no circumstances attempt
to adjust or loosen fittings without
prior reference to your authorised
simba dealer, and detailed
maintenance instructions.
5. Servicing and Maintenance
5.9 Operator Support
If you have a problem, please contact your
dealer. They will endeavour to solve any
problems which may occur and provide you
with support at all times.
5.8 Preparation for
Storage
If you need to store the machine for a longer
period, observe the following points:
• Park the machine undercover if possible.
• Protect the roll / discs against rust. If you
need to spray the implements with oil, use
light biologically degradable oils, e.g. rape
oil.
In order to enable your dealer to deal with
problems as quickly as possible, it helps if
you can provide them with the following data.
Always state the:
• Customer Number
• Name and Address
• Machine Model
• Serial Number of Machine
• Date of Purchase and Operating Hours
• Type of Problem
Avoid sharp-edged and pointed
parts (disc blades, etc.) when
working on the machine.
Place the machine on suitable
supports when working
underneath! Do not work under a
machine which is not supported!
On a new machine tighten all nuts and bolts
after 5 hours work and again after 15 hours.
This also applies to parts that have been
moved or replaced. After the initial 15 hours
of work a once a week check should be
sufficient depending on daily work rates.
5.10 Maintenance
Intervals
Apart from daily maintenance, the
maintenance intervals are based on the
number of operating hours and time data.
Keep a record of your operating hours to
ensure that the specified maintenance
intervals are adhered to as closely as
possible.
Never use a machine that is due for
maintenance. Ensure that all deficiencies
found during regular checks are remedied
immediately.
