Rotating Machinery
a. Entanglement with any rotating equipment can
cause serious injury or death.
b. If unprotected skin comes into contact with rotating
equipment severe burns can result.
Safe Maintenance Considerations
a. Understand the service procedures before
commencing any work.
b. Ensure the work area is clean, dry, well ventilated
and has adequate lighting.
c. Isolate the engine starting system before
commencing any work on the plant.
d. All persons using equipment or processes in
connection with the maintenance of plant and
machinery must have received adequate and
suitable training.
High Pressure Fluids
a. Never allow any part of the body to come into
contact with high pressure hydraulic oil,
compressed air or fuel oil, for example when testing
fuel injection equipment.
b. Both digested and ingested fluids can lead to
serious injury, possibly with fatal results in a very
short period of time.
Electrical System Considerations
a. Ensure that the battery is of sufficient capacity to
start the engine down to its minimum operating
temperature taking into account any drag that may
be imposed on the engine by the type of
transmission that is attached to it.
b. Ensure the battery and all engine wiring cables
are of sufficient size to carry the currents required.
c. Check that the engine mounted alternator is of
sufficient output to cope with the total electrical
load required by the machine to which it is fitted.
d. Ensure engine wiring cables are:
Bound together in a loom and adequately
supported.
Routed to avoid any hot surfaces, particularly the
exhaust system.
Not in contact with any rough surfaces or sharp
corners so as to avoid any possibility of chaffing
taking place
Alternator/Charge Windings Precautions
a. Never remove any electrical cable while the battery
is connected in the circuit.
b. Only disconnect the battery with the engine
stopped and all switches in the OFF position.
c. Ensure cables are fitted to their correct terminals.
A short circuit or reversal of polarity will ruin diodes
and transistors. Never connect a battery into the
system without checking that the voltage and
polarity are correct.
d. Never flash any connection to check the current
flow or experiment with any adjustments or repairs
to the system.
e. The battery and alternator/charge windings must be
disconnected before commencing any electric welding
when a pole strap is directly or indirectly connected to
the engine.
f. Starting engines that are fitted with charge windings
which have been disconnected from the batter will
cause irreparable damage unless the stator leads
from the rectifier/regulator have been removed.
Starter Battery Precautions
WARNING
Sulphuric acid in battery electrolyte is poisonous, is strong
enough to burn skin, eat holes in clothing and cause
blindness if splashed into the eyes.
a. Do not smoke near the batteries and keep sparks
and flames away from them.
b. Batteries contain sulphuric acid - if the acid has
been splashed on the skin, eyes or clothes flush it
away with copious amounts of fresh water and seek
immediate medical aid.
c. Keep the top of the battery well ventilated during
charging. Switch off the battery charger before
connecting or disconnecting the charger leads.
d. Disconnect the battery negative (earth) lead first
and reconnect last.
e. Never 'flash' connections to check current flow.
f. A damaged or unserviceable battery must never
be used.
g. Do not attempt to charge a frozen battery; it may
explode; warm the battery to 16°C (60°F).
Asbestos Dust
a. Avoid breathing dust that may be generated when
handling components containing asbestos fibres.
Inhaled asbestos fibres may cause lung cancer.
b. Components that may contain asbestos include
brake pads, brake band and lining assemblies,
clutch plates and some gaskets.
The asbestos in these products is usually found in
a resin or it is sealed.
Normal handling is not hazardous as long as
airborne dust containing asbestos is not generated.
Oil Seals Containing Viton
Some engines may be fitted with seals or 'O' rings
manufactured from 'Viton' or a similar material.
When exposed to abnormally high temperatures,
in excess of 400°C (752°F), an extremely corrosive
acid is produced which cannot be removed from the
skin.
If signs of decomposition are evident, or if in doubt,
always wear disposable heavy duty gloves.
