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 saw 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 the workpiece 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 lines on top of
the "sandwich".
