TROUBLESHOOTING PROCEDURES
WARNING
Fuels used in the Bituminous Material Paving Machine (BMPM) are combustible and toxic to
eyes, skin, and respiratory tract. Skin and eye protection are required when working in
contact with fuel. Avoid repeated or prolonged contact. Provide adequate ventilation. Wash
exposed skin and change soaked clothing promptly if exposed to fuel. Failure to comply may
cause injury or death to personnel.
Never inject fuel near a fire source. Atomized fuel is highly combustible. Fuel pressure is high
enough to penetrate skin. Ensure spray from the injector nozzle is directed away from all
personnel. Direct contact with spray can cause skin cell destruction and blood poisoning.
Skin and eye protection are required when working in contact with fuel. Failure to comply may
cause injury or death to personnel and damage to equipment.
