Fuel Injector Check
Keep hands well away from operating nozzles!
The fuel jet from a nozzle can penetrate deep into
the flesh and destroy tissue. Fuel entering the
bloodstream can cause blood poisoning.
Under no circumstances use petrol (gasoline) to
test the injection nozzles.
Risk of explosion!
Only use ISO 4113 test oil.
Test oil and resulting vapour is inflammable and
could cause an explosion.
Do not permit oil vapour to enter the workplace
atmosphere!
Use a ventilation system. No naked flames, no
electric sparks. No smoking.
