Accident Prevention; Safety Requirements For Fluid Power Systems And Components - New Holland T6.140 Service Manual

ACCIDENT PREVENTION

WARNING
Avoid injury! Always do the following before lubricating, maintaining, or servicing the machine.
1. Disengage all drives.
2. Engage parking brake.
3. Lower all attachments to the ground, or raise and engage all safety locks.
4. Shut off engine.
5. Remove key from key switch.
6. Switch off battery key, if installed.
7. Wait for all machine movement to stop.
Failure to comply could result in death or serious injury.
Most accidents or injuries that occur in workshops are the result of non compliance to simple and fundamental safety
principles. For this reason, IN MOST CASES THESE ACCIDENTS CAN BE AVOIDED by applying the fundamental
safety principles, acting with the necessary caution and care.
Accidents may occur with all types of machine, regardless of how well the machine in question was designed and
built.
SAFETY REQUIREMENTS FOR FLUID POWER SYSTEMS AND COMPONENTS - HY-
DRAULICS (EUROPEAN STANDARD EN982)
• Flexible hose assemblies must not be constructed from hoses which have been previously used as part of a hose
assembly.
• Do not weld hydraulic pipes: when flexible hoses or piping are damaged, replace them immediately.
• It is forbidden to modify a hydraulic accumulator by machining, welding or any other way.
• Before removing hydraulic accumulators for servicing, the liquid pressure in the accumulators must be reduced to
zero.
• Pressure check on hydraulic accumulators must be carried out by a method recommended by the accumulator
manufacturer.
• Take care not to exceed the maximum allowed pressure of the accumulator. After any check or adjustment, check
for leakages or gas in the hoses or pipes.
SAFETY RULES
General guidelines
• Carefully follow specified repair and maintenance procedures.
• When appropriate, use P.P.E (Personal Protective Equipment)
• Do not wear rings, wristwatches, jewellery, unbuttoned or loose articles of clothing such as: ties, torn clothing,
scarves, open jackets or shirts with open zips that may remain entangled in moving parts. It is advised to wear
approved safety clothing, e.g.: non-slip footwear, gloves, safety goggles, helmets, etc.
• Do not carry out repair operations with someone sitting in the driver's seat, unless the person is a trained technician
who is assisting with the operation in question.
• Do not operate the machine or use any of the implements from different positions, other than the driver's seat.
• Do not carry out operations on the machine with the engine running, unless specifically indicated.
• Bring all hydraulic cylinders to the home positions (down, retracted, etc.) before engine shut down.
• Stop the engine and check that the hydraulic circuits are pressure-free before removing caps, covers, valves, etc.
• All repair and maintenance operations must be carried out using extreme care and attention.
• Service steps and platforms used in the workshop or elsewhere should be built according to the applicable stan-
dards and legislation.
• Disconnect the power take off (p.t.o). and label the controls to indicate that the machine is being serviced. Any
parts that are to be raises must be locked in position.
