5. Continue lowering the blade into the workpiece until the jig saw 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 jig saw. 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 vice if possible
and saw close to the vice. 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".
