Safe Maintenance Considerations
a. Understand the service procedures be-
fore 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 process-
es 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 injested 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 tak-
ing 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 alterna-
tor 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, par-
ticularly the exhaust system.
Not in contact with any rough surfaces
or sharp corners so as to avoid any pos-
sibility of chaffing taking place
Charge Winding Precautions
The following points must be strictly
observed when charge windings are fitted
otherwise serious damage can be done.
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.
Always ensure that cables are fitted to
their correct terminals.
A short circuit or reversal of polarity will
ruin diodes and transistors.
d.
Never connect a battery into the system
without checking that the voltage and
polarity are correct.
e.
Never flash any connection to check the
current flow.
f.
Never experiment with any adjustments
or repairs to the system.
g.
The battery and charge windings must
be disconnected before commencing
any electric welding when a pole strap
is directly or indirectly connected to the
engine.
WARNING
Starting engines that are fitted with
charge windings which have been dis-
connected from the battery will cause
irreparable damage unless the stator
leads from the rectifier/regulator have
been removed.

Rotating Machinery
a. Entanglement with any rotating equip-
ment can cause serious injury or death.
b. If unprotected skin comes into contact
with rotating equipment severe burns
can result.
c. Some accessories may require guards
which must be supplied and fitted by the
purchaser.
