OPERATION
METAL CUTTING
See Figure 12.
Many kinds of metals can be cut with the saw. Be careful
not to twist or bend the blades.
Do not force.
If the blade
chatters or vibrates excessively, use a finer-tooth metal-
cutting blade. If blade heats excessively, use lower speed. If
blade teeth become filled or clogged when cutting soft met-
als, such as aluminum, use a coarser-tooth blade or lower
speed. We recommend use of oil when cutting metals to keep
blades cool, increase cutting action, and prolong blade life.
Clamp the work firmly and saw close to the clamping point
to eliminate any vibration of the work being cut.
When cutting conduit, pipe, or angle iron, clamp work in a
vise if possible and saw close to the vise. To cut thin sheet
materials, “sandwich” the material between hardboard or
plywood and clamp the layers to eliminate vibration and
material tearing. By doing this, the material will be cut
smoothly. Lay out your pattern or line of cut on top of the
“sandwich.”
NOTE:
When cutting metal, keep exposed portion of saw
blade clean and free of metal chips by wiping frequently with
an oily cloth. Use extreme caution in disposing of oily cloth
after completion of job to prevent potential fire hazard.
