Remove Paint before Welding or Heating

Avoid potentially-toxic fumes and dust.
Hazardous fumes can be generated when paint is heated
by welding, soldering, or when using a torch.
Remove paint before heating:
•
Remove paint a minimum of 100 mm (4") from the area
affected by heating. If paint cannot be removed, use an
approved respirator before heating and/or welding.
•
If you sand or grind paint, avoid breathing the dust;
wear an approved respirator.
•
If you use solvent or paint stripper, remove the stripper
with soap and water before welding. Remove solvent or
paint stripper containers and other flammable material
from the area. Allow fumes to disperse at least 15
minutes before welding or heating.
Do not use a chlorinated solvent in areas where welding
will take place.

Make Welding Repairs Safely

IMPORTANT: Disable electrical power before welding.
Separate harness connectors from the engine
and vehicle microprocessors.
Avoid welding or heating near pressurised fluid lines.
Flammable spray may eject and cause severe burns if
pressurised lines fail as a result of heating. Do not let heat
extend beyond the work area.
Remove paint properly. Do not inhale paint dust or fumes.
Use a qualified welding technician for structural repairs.
Ensure there is good ventilation, and wear eye protection
and other protective equipment when welding.

Service Accumulator Systems Safely

Escaping fluid or gas from pressurized hydraulic
accumulator systems can cause serious injury. Extreme
heat can cause the accumulator to burst, and pressurized
lines can be accidentally cut. Do not weld or use a torch
near a pressurized accumulator or line.
Relieve pressure from the hydraulic system before
removing the accumulator.
Safety—Maintenance Precautions
Carry out work in a well-ventilated area to carry toxic
fumes and dust away.
Dispose of paint and solvent properly.
Keep the welder ground clamp as close to the welded
area as possible to prevent welding current travelling
through the electrical system.
