Maintenance Safety
General
Raised Machine
Never position yourself or any part of your body under a raised machine which is not correctly supported. If the
machine moves unexpectedly you could become trapped and suffer serious injury or be killed.
Air Conditioning Maintenance
The air conditioning system is a closed loop system and contains pressurised refrigerant. No part of the system
should be disconnected until the system has been discharged by a refrigeration engineer or a suitably trained
person. You can be severely frostbitten or injured by escaping refrigerant.
Compressed Air
Compressed air is dangerous. Wear personal protective equipment. Never point a compressed air jet at yourself
or others.
Springs
Always wear personal protective equipment when dismantling assemblies containing components under
pressure from springs. This will protect against eye injury from components accidentally flying out.
Metal Splinters
You can be injured by flying metal splinters when driving metal pins in or out. Use a soft faced hammer or
copper drift to remove and install metal pins. Always wear personal protective equipment.
Communications
Bad communications can cause accidents. If two or more people are working on the machine, make sure each
is aware of what the others are doing. Before starting the engine make sure the others are clear of the danger
areas. Examples of danger areas are: the rotating blades and belt on the engine, the attachments and linkages,
and anywhere beneath or behind the machine. People can be killed or injured if these precautions are not taken.
Repairs
If your machine does not function correctly in any way, get it repaired straight away. Neglect of necessary
repairs could result in an accident or affect your health. Do not try to do repairs or any other type of maintenance
work you do not understand. To avoid injury and/or damage get the work done by a specialist engineer.
Hydraulic Pressure
Hydraulic fluid at system pressure can injure you. Before connecting or removing any hydraulic hose, residual
hydraulic pressure trapped in the service hose line must be vented. Make sure the hose service line has been
vented before connecting or removing hoses. Make sure the engine cannot be started while the hoses are open.
'O' rings, Seals and Gaskets
Badly installed, damaged or rotted 'O' rings, seals and gaskets can cause leakages and possible accidents.
Renew whenever disturbed unless otherwise instructed. Do not use Triochloroethane or paint thinners near
'O' rings and seals.
Arc Welding
To prevent the possibility of damage to electronic components, disconnect the battery and the alternator before
arc-welding on the machine or attached implements.
If the machine is equipped with sensitive electrical equipment, i.e. amplifier drivers, electronic control units
(ECUs), monitor displays, etc., then disconnect them before welding. Failure to disconnect the sensitive
electrical equipment could result in irreparable damage to these components.
Parts of the machine are made from cast iron, welds on cast iron can weaken the structure and break. Do not
weld cast iron. Do not connect the welder cable or apply any weld to any part of the engine.
Always connect the welder earth (ground) cable to the same component that is being welded to avoid damage
to pivot pins, bearings and bushes. Attach the welder earth (ground) cable a distance from the part being
welded no more than 0.6m.
Counterweights
Your machine may be installed with counterweights. They are extremely heavy. Do not attempt to remove them.
