Batteries
The batteries contain a highly corrosive
electrolyte (sulphuric acid). Take care to
protect your eyes, skin and clothes when
charging or handling batteries. Wear protective
gloves and goggles.
If the acid splashes on your skin, wash it off
with soap and copious amounts of water. If acid
splashes in your eyes, flush them immediately
with copious amounts of water and contact a
doctor.
Dispose of used batteries through an
authorised waste disposal contractor.
Electrical system
The engine must be stopped and the power
disconnected using the master switch or
battery master switch before working on the
electrical system.
External power supplies to extra equipment on
the engine must also be disconnected.
Electric welding
When carrying out welding work close to and
on the engine, remove the battery leads and
the leads to the alternator. Also remove the
multi-pin connector to the control unit.
Connect the weld clamp to the component to be
welded and close to the welding point, never to
the engine or in such a manner that the current
can pass over to a mounting.
When you have finished welding, connect the
leads to the alternator and control unit before
connecting the batteries.
Lubrication system
Hot oil can cause burns and skin irritation.
Therefore, avoid skin contact with hot oil.
Make sure that there is no pressure in the
lubricating system before starting work on it.
Never start or run the engine with the oil filler
cap removed, as this may cause oil to be
thrown out.
Dispose of used oil through an authorised
waste disposal contractor.
Cooling system
Never open the coolant filler cap if the engine is
hot. Hot coolant or steam may spray out and
cause burns.
If you have to open or remove a cooling system
component when the engine is hot, open the
cap very carefully and slowly to relieve the
system pressure before removing the cap.
Wear gloves as the coolant is still very hot.
Dispose of used coolant through an authorised
waste disposal contractor.
Fuel system
Always wear gloves when looking for leaks or
carrying out any other work on the fuel system.
Also wear protective goggles when testing
injectors.
Fuel escaping at high pressure can penetrate
tissues and cause serious injury.
Never use non-genuine parts in the fuel and
electrical systems as genuine parts are
designed and manufacture to minimise the risk
of fire and explosion.
Before starting
Fit all removed shields before starting the
engine again. Check that you have not left any
tools or other objects on the engine.
Never start the engine without the air filter
fitted. There is a risk of objects being sucked
into the impeller or of injury if you come into
contact with it.
