Maintenance & Care
General Safety and Accident Prevention Advice
1 Make sure that if the tractor remains attached to the drill
that the ignition key is removed.
2 During maintenance the drill should be supported in such
a manner that if hydraulic failure was to occur the machine
would still be adequately supported.
3 Wear gloves when handling components with cutting
edges such as worn discs etc...
4 Disconnect the electrical supply from the tractor before
doing any electrical maintenance.
5 Refer to safety sections for more safety information.
General Cautionary Maintenance Advice
1 Electric Welding - With the electronic equipment in
modern tractors it is advisable to completely disconnect the
implement from the tractor, or at the very least disconnect
the alternator before attempting any welding.
2 Hydraulics - Ensure hydraulic couplings (male & female)
are clean before connecting. Dirty couplings will result in
hydraulic oil contamination and hydraulic cylinder seal and
valve damage. This in turn will result in oil leakage.
No filter is fitted to the hydraulic system. If hydraulic
fittings and oil supply are not going to be kept clean it is
recommended that a filter be fitted to prevent hydraulic
cylinder damage.
3 Water Blasting - Water blasting, steam cleaning or other
pressurised cleaning processes can force dirt etc. into
undesirable places that may cause damage or rapid part
wear to items such as bearings, seals, chains, bushes and
electical items etc.
Caution must be exercised.
