Technician Safety Information


1. Block the drive wheels, as a safety routine, before beginning any service with the vehicle on the ground.
2. Never work under a vehicle supported only by a jack. Use jackstands, on a flat and level hard surface, for safe support.
3. Always wear appropriate eye protection.
4. Use caution when working near the catalytic converter to prevent the possibility of burns. The temperatures within the converter can exceed 1000°F.
5. Ignition systems present a shock hazard; exercise care when performing spark test and always use non-conductive ignition wire pliers.
6. When servicing the fuel system observe the following cautions:
a. Put a "CAUTION: FLAMMABLE" sign in the workshop.
b. Be sure the shop is furnished with the proper fire extinguisher.
c. Be sure to disconnect battery ground cable before any service work is done.
d. Place a suitable container under the connection to be opened.
e. Slowly open fuel connections, allow pressure to escape, and catch spilled fuel in container.

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

f. Disconnect line or hose, then plug all fittings.
g. Put any drained fuel in an explosive-proof container and put the lid on securely.
