1.9 Servicing &
Maintenance
Ensure that regular checks and inspections
are always carried out within the periods
required by law or specified in these
Operating Instructions.
When carrying out service and maintenance
work always:
• switch off the tractor engine and remove
the ignition key.
• wait until all the machine parts have
stopped moving.
• depressurise the hydraulic system.
Many hydraulic circuits contain lock or
overcentre valves which can retain pressure
in the lines even after depressurising the
tractor side of these circuits. If in doubt,
consult trained personnel (such as your local
Great Plains Dealer) to ensure such valves
are depressurised to the correct procedure
before removing or servicing any parts
connected downstream of these valves.
Check all hydraulic lines for leaks, loose
connections, chafe marks and damage.
Remedy any deficiencies immediately! Pay
particular attention to hose renewal intervals
as outlined in the specific sections which
follow. ALL hydraulic hoses have a safe
maximum working life of 6 (SIX) years from
date of installation, provided they remain in a
safe condition. Hoses which exceed 6 years
of age should be replaced, or inspected and
certified by a suitably qualified person to
have an extended life period which should
be recorded.
Pay particular attention to those items which
require specialist service tools or training
to be carried out by qualified personnel. Do
not attempt to service these items yourself!
These include items retaining pressure (e.g.
hydraulic circuits), or force (e.g. spring tines
/ levelling boards).
Prior to performing maintenance and
servicing work, ensure that the machine
is positioned on solid, level ground and is
secured to prevent it rolling away. Do not
use any parts to climb on to the machine
unless they are specifically designed for
this purpose.
Before cleaning the machine with water,
steam jets (high-pressure cleaning
apparatus) or other cleaning agents, cover
all openings into which, for reasons of safety
or operation, no water, steam or cleaning
agents are to penetrate (bearings, for
instance).
Lubricate all the lubricating points to force
out any trapped water.
When carrying out servicing and maintenance
work, retighten any loose screw connections.
When servicing the machine take precautions
against soil, dust, seed coatings, oil or any
other hazardous substances that you might
encounter.
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.
