Operating Instructions
1. Safety Data
1.7 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 Simba 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. accumulator circuits), or force (e.g.
spring tines), and DD axles of any type.
