Electrical Risks
Electrical checks must be carried out regularly.
Electric wiring must be kept in good condition, properly positioned and soundly
attached.
All wires should be of the recommended size.
Wires and cables must be protected by a fuse or calibrated circuit breaker.
Do not short-circuit fuses and/or circuit breakers.
The electrical circuit of the engine must be isolated from the engine and generator.
Ensure that the engine is grounded correctly to prevent uncontrolled electrical circuit
paths which can cause damage.
Insulation problems can cause short-circuits or stray current. Stray current can
damage electrical and electronic components, bushing or crankshaft seating and may
also cause radio-frequency disturbance.
The engine earth must be properly connected to the chassis, as well as all the flexible
hoses.
Flexible connections for cooling
Flexible circuit connections fuel
Electrical control systems and electronic fuel injection
Earth faults can cause corrosion in the pipes and engine or genset unit components.
Lines, Tubes and Hoses
Ensure that all high pressure lines are not bent, worn or damaged. High pressure lines
must be positioned, supported and firmly fastened. Do not attach any other
components to the high pressure lines. Tighten all connections to the recommended
torque.
Do not check for leaks using your hand. Use a cardboard to check for a leak.
Tighten all connections and filter housings to the recommended torque.
Release the lubrication, fuel and pressure cooling circuits before disconnecting or
removing hoses or associated parts.
Coolant Safety
At operating temperature, the coolant is hot and pressurized. When pressure is
released sharply, this hot liquid may be transformed into fumes. Any contact with this
hot liquid or these fumes may cause serious burns.
The cooling system also contains alkali which can cause injury. Do not allow alkali to
contact your skin, eyes or mouth.
Let the components of the coolant circuit cool down before draining the circuit.
Only check the coolant level when the engine has stopped.
Once the system has cooled, slowly unscrew the coolant filler plug to release
pressure.
