Technician Safety Information
1. Always wear appropriate eye protection.
2. Use caution when working near the catalytic converter to prevent the possibility of burns. The temperatures within the converter can exceed 1000°F.
3. Ignition systems present a shock hazard; exercise care when performing spark test and always use non-conductive ignition wire pliers.
4. When servicing the fuel system use the following precautions:
a. Set up a "CAUTION: FLAMMABLE" sign in the workshop area.
b. Be sure the shop is equipped the proper fire extinguisher.
c. Disconnect the negative battery cable before starting service work.
d. Place a suitable container under the connection to be opened.

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