PLUNGE CUTTING – cont'd

Start the saw and slowly lower the

blade onto the workpiece while making

sure the front of the sole plate remains

in contact with the workpiece. Allow

the blade to cut through the wood.

Continue lowering the blade into the

workpiece until the sole plate 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

tooth blade. If the blade heats excessively,

reduce 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. 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 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

lines on top of the "sandwich".
