surface in front of the saw, the footplate
may be repositioned as follows:
Loosen screw, move the footplate back
in the 0° alignment slot, and securely
tighten screw. Note that when the
footplate is retracted in this manner,
only 90° cuts are possible, and the
optional cutting guide and anti-splinter
insert guide may not be used.
Tool Tips
gripping surfaces on the front of the
tool and the switch handle. Failure to
hold the tool by the insulated gripping
surface my result in electic shock or
electrocution if sawing into a blind area
where live wiring exits.
Always be
workpieces are securely fastened to a
bench or other support. Larger panels
may be held in place by clamps on a
bench or sawhorses.
To begin a cut, clearly mark the cutting
line, and rest the front of the footplate
on the work. Engage the switch, and
move the blade into the work using only
enough forward pressure to keep the
blade cutting steadily. Do not force, as
this will not make the saw cut faster; let
the blade do the work.
When sawing metal or similar materials,
apply coolant/lubricant alongside the
cutting line.
Use of reverse-tooth blade such as the
Bosch T101BR requires the orbital
setting to be "0" and that downward
pressure be applied to the top of the
saw.

Blade Selection

• Choose blades carefully, as the ability
of the jigsaw to make the fastest
cuts, to follow tight curves, to
achieve the smoothest finish and/or
to maximize the life of the blade are
directly related to the type of blade
used.
• Always
appropriate for the cutting task.
• Always make a test cut in a piece of
scrap material.
Operating Instructions
Always hold the saw
by the insulated

• For tight curves it is best to use a
narrow or scroll blade.
• Most jigsaw blades have upward-
pointing teeth, which helps to pull
the jigsaw against the workpiece and
minimizes vibration. Blades with
upward-pointing teeth produce a
clean cut on the bottom of the
workpiece.
• Blades with downward-pointing teeth
(reverse-tooth blade) can be used to
produce a clean cut on the top of the
workpiece (that side that faces the
jigsaw's footplate), such as when
cutting
countertop from the top. When using
reverse-tooth blades, downward
force must be applied to the jigsaw.
• Blades with teeth that point straight
out (rather than up or down) allow
splinter-free cutting on both sides of
the workpiece. When using such
blades, downward force must be
applied to the jigsaw.
• The following types of blades should
only be used with orbital Setting 0:
1. Blades with teeth that point
downward (reverse-tooth blades).
2. Blades with teeth that point
straight out rather than up or
down.
3. Carbide-tipped blades.
4. Grit-edge blades.

Plunge Cutting

Plunge cutting is useful and time-saving
in making rough openings in softer
materials. It is not necessary to drill a
hole for an inside or pocket cut. The
is
longest blade to be used for plunge
cutting is 3-1/8" (80 mm). Footplate
must be set 0° setting.
Draw lines for the opening, hold the saw
