WELDING AND GRINDING WORK PRECAUTIONS
IMPORTANT! A fire extinguisher should be easily accessible during all welding work.
 Welding repairs are to be performed by a trained welder with proper service instructions.
Know the material to be welded and select the correct welding procedure and materials
(electrodes, rods, wire) that will provide a weld metal strength equivalent to the parent
material.
 Move the machine to a clean, safe area before welding, grinding or using a cutting torch on
it. This type of work should only be done in a clean area and not in places that contain
combustible liquids, such as fuel tanks, hydraulic pipes or similar.
 Connect arc welder ground as close as possible to work area.
 Work with extra care when welding, grinding or torch cutting near flammable objects.
WORKING ON PAINTED SURFACES
Heated paint gives off poisonous gases. Therefore, paint must be removed from an
area with a radius of at least 4 in (10 cm) before carrying out welding, grinding,
or gas cutting. In addition to the health hazard, the weld will be of inferior
quality and strength if the paint is not removed.
Methods and precautionary measures when removing paint:
 Blasting – use respiratory protective equipment and protective goggles.
 Paint remover or other chemicals – use a portable air extractor, respiratory protective
equipment, and protective gloves.
 Grinding – use a portable air extractor, respiratory protective equipment, and protective
gloves and goggles.
