Technician Safety Information

Always wear appropriate eye protection.

To prevent burns, use caution when working near catalytic converters. Catalytic converter temperatures can exceed 1000°F.

Ignition systems present a shock hazard; exercise care when performing spark test and always use non-conductive ignition wire pliers.

When servicing the fuel system use the following precautions:

- Set up a "CAUTION: FLAMMABLE" sign in the workshop area.

- Be sure shop is equipped with the proper fire extinguisher.

- Disconnect negative battery cable before starting service work.

- Place a suitable container under connection to be opened.

- Place a shop cloth over fittings to be disconnected. This will catch any pressurized spray when the lines are opened.

- Slowly open connection, allow pressure to escape, and catch spilled fuel in container.

NOTE: If available, use system bleed valve (schrader) to relieve pressure.

- After disconnecting line(s) or hose(s), plug all fittings.

- Put any drained fuel in an explosive-proof container with a secure fitting lid.
