TOOL TIPS
Always be certain that smaller 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.
Choose blades carefully, as the ability of the
jig saw to follow curves, provide smoother
finishes, or faster cutting is directly related to
the type of blade used (See your Bosch
Dealer).
For tight curves it is best to use a narrow or
scroll blade.
When sawing metal or similar materials, shut
off chip blower and 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.

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 longest blade to be used for
plunge cutting is 3-1/8" (80 mm). Footplate
must be set 0° setting. (Fig. 7).
Draw lines for the opening, hold the saw
firmly, tilt it forward so that the toe of the saw
foot rests on the work, but with the blade well
clear of the work. Turn the tool on and run at
JA1010 CIRCLE AND PARALLEL
CUTTING GUIDE
The JA1010 is used for fast and accurate straight
and circle cutting. It includes the guide, two clamps
for attaching it to the jig saw (A), and a center pin
for guiding circle cuts (B). The clamps and the
centering pin can be stored on the guide (Fig. 9).
One end of the clamp is used to attach the guide's
bar to jig saws that have narrow tops on their
footplate mounting slots (C) and the other end is
used to attach the guide's bar to jig saws that have
wide tops on their footplate mounting slots (D) (Fig.
10).
When possible, attach the bar to the jig saw using
both clamps for enhanced grip and precision.
top speed, and then very gradually lower the
blade (Fig. 8).
When it touches, continue pressing down on
the toe of the saw foot slowly pivoting the saw
like a hinge until the blade cuts through and
the foot rests flat on the work. Then saw
ahead on the cutting line. We do not
recommend plunge cutting with a scroll blade.
Do not try to plunge cut into hard materials
such as steel.
To make sharp corners, cut up to the corner,
then back up slightly before rounding the
corner. After the opening is complete, go back
to each corner and cut it from the opposite
direction to square it off.
