PRECAUTIONS FOR WELDING, CUTTING,
AND GRINDING
When performing any welding operation on a rigid dump
truck,
specific
electrical
disconnected. Refer to Electrical Disconnects before
Welding in the MAINTENANCE section of this manual.
Grinding on the rigid dump truck may create fire
hazards. Store flammable objects in a safe place before
starting grinding.
NOTE: A high speed-grinding rigid dump truck will heat
the paint and must only be used in a well-
ventilated area.
Be sure to perform welding in a well ventilated and
prepared area. Store flammable objects in a safe place
before starting welding.
Only qualified personnel should perform welding. Never
allow an unqualified person to perform welding.
After completing the welding, recheck that there are no
abnormalities such as the area surrounding the welded
area still smoldering.
REMOVE PAINT BEFORE WELDING OR
CUTTING
Paint must be removed up to a distance of 10 cm (4 in)
from the welding or cutting point.
Remove the paint from the area work is to be performed
through sand blasting.
• If you sand blast or grind paint, avoid breathing the
dust. Wear an approved respirator.
• Work outside or in a well-ventilated area.
If the paint cannot be removed by sand blasting, it must
be removed in some other way e.g., with paint stripper.
• Wear protective gloves and work outside or in a well-
ventilated area.
• Dispose of paint and solvent properly.
• If you use solvent or paint stripper, remove stripper
with soap and water before welding.
• Remove solvent or paint stripper containers and other
flammable material from area. Allow fumes to
disperse at least 15 minutes before welding or cutting.
