Welding Safety
Flame cutting or welding on painted
surfaces may produce potentially
harmful fumes, smoke, and vapors.
Remove any coating in the vicinity
where the operation(s) will be
performed prior to performing flame
cutting or welding operations.
Coating removal may be by mechanical
methods, chemical methods, or a
combination of methods. Perform flame
cutting and/or welding operations only
in well ventilated areas. Use local
exhaust if necessary.

• Check for shorts to frame as identified on
page 5-5. If any shorts are found, remove
them before you proceed with the welding
operation.
• Clean the area to be welded.
• Protect all truck components from heat,
weld spatter, and debris.
• Attach the ground cable to a clean,
unpainted surface as close to the weld
area as possible.
• Do not perform any welding operations
near the electrical components.
• Do not attach the ground cable to
fasteners or other removable components.
• If you must weld near the battery
compartment, remove the battery from the
truck. See “Lead Acid Battery” on
page 7-40.
• When you are finished welding, perform all
ground tests and electrical inspections
before operating the vehicle.
