5. Continue lowering the blade into the
workpiece until the jigsaw base rests
flat on the workpiece. Continue
sawing toward the cutting line and
complete the cut as required.
METAL CUTTING
Many types of metal can be cut with your
jigsaw. When cutting any kind of material,
be careful not to twist or bend the blades.
Do not force the blade. If the blade
chatters or vibrates excessively, use a
finer toothed blade. If the blade heats
excessively, reduce the speed of cutting. If
the blade teeth become clogged when
cutting soft metals, such as aluminum, use
a coarser blade with fewer teeth per inch.
Use kerosene when cutting soft metals
and oil when cutting steel to keep the
blade cool and to extend the blade life.
Clamp all work firmly and jigsaw as close
as possible 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 material vibration and
tearing. By doing this, the material will be
cut smoothly. Lay out your pattern or
cutting li
nes on top of the “sandwich”.
