Plunge Cutting
See Figure 13, 14 and 15.
WARNING:
To avoid loss of control, broken blades, or dam-
age to the material being cut, always use extreme
caution when making plunge cuts. We do not
recommend plunge cutting on materials other than
wood.
To Make A Plunge Cut
■ Mark the line of cut clearly on the workpiece.
■Set the orbit adjustment to 0 (zero).
■ Tilt the saw forward so that it rests on the front edge of
the base and blade will not come in contact with the
workpiece when the saw is turned on.
■ Make sure the blade is inside the area to be cut.
■ Using high speed, start the saw and slowly lower the
blade into the workpiece until the blade cuts through
the wood.
See Figure 13.
■ Continue lowering the blade into the workpiece until
the base rests flat on the work surface, then move the
saw forward to complete the opening.
■ Use only the 7 teeth per inch blade for this type of cut.
Metal Cutting
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 metals, 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."
Important – When cutting metal, keep exposed portion of
saw bar 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.
