General Safety Instructions
WARNING
●
●
●
●
Fuel and test oil are very flammable and
can explode easily. To avoid serious injury
or death, keep fuel away from open fire
and keep fire extinguisher within easy
reach when working with fuel.
When working with fuel, post signs that
read “NO SMOKING WITHIN 50 FEET.”
When testing or adjusting fuel injectors, do
not place hands or arms in front of injector
spray tip.
Fuel spray from an injector has sufficient
penetrating power to puncture the flesh
and destroy tissue. Should fuel enter blood
stream, it can cause blood poisoning.
