8. Metal Cutting

The saw can be used to cut metals, such as sheet steel, pipe, steel rods, aluminum, brass, and
copper. Be careful not to twist or bend the saw blade. Do not force the tool.
The use of cutting oil is recommended when cutting soft metals and steel. Cutting oil will keep the
blade cool, increase cutting action, and prolong blade life.
WarninG: Never use gasoline as cutting oil; normal sparking could ignite the fumes.
a. Securely clamp the workpiece in position, and make the cut close to the clamping point to
minimize vibration.
b . When cutting conduit pipe or angle iron, clamp the workpiece in a vise. If possible, cut close to
the vise to prevent the workpiece from shaking and to prevent kickback.
c . To cut thin sheet material, sandwich the material between pieces of hardboard or plywood and
clamp the layers together to reduce vibration and tearing of the material.

Care and mainTenanCe

WarninG: All maintenance should only be carried out by a qualified repair person.
Cleaning

and proper operation, always keep the tool and its ventilation slots clean. Only use a soft, dry cloth to
