Precautions For Welding And Grinding; Avoid Heating Near Pressurized Fluid Lines; Avoid Applying Heat To Lines Containing Flammable Fluids - Hitachi Zaxis 110 Zaxis 125US Workshop Manual

PRECAUTIONS
GRINDING
•
Welding may generate gas and/or small fires.
•
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.
•
Grinding on the machine may create fire hazards.
Store flammable objects in a safe place before
starting grinding.
•
After finishing welding and grinding, recheck that
there are no abnormalities such as the area sur-
rounding the welded area still smoldering.
AVOID HEATING NEAR PRESSURIZED
FLUID LINES
•
Flammable spray can be generated by heating near
pressurized fluid lines, resulting in severe burns to
yourself and bystanders.
•
Do not heat by welding, soldering, or using a
torch near pressurized fluid lines or other
flammable materials.
•
Pressurized lines can be accidentally cut when
heat goes beyond the immediate flame area.
Install temporary fire-resistant guards to protect
hoses or other materials before engaging in
welding, soldering, etc..
AVOID APPLYING
CONTAINING FLAMMABLE FLUIDS
•
Do not weld or flame cut pipes or tubes that
contain flammable fluids.
•
Clean them thoroughly
solvent before welding or flame cutting them.
