FOOTPLATE ANGLE ADJUSTMENT

The footplate may be tilted to allow angle cuts
up to 45° in either direction (Fig. 7).
Note: before adjusting the footplate, remove
anti-splinter insert if used.
Open the lock lever to unlock footplate. Push
and hold the footplate firmly towards the back
of tool as shown. While holding the footplate
backwards tilt footplate to desired angle on
bevel scale, then release pressure on footplate
so it engages into detent at desired angle (Fig. 7).

Your tool has detent slots the footplate will
engage at 0° & 45°, and there are additional
position marks for 15°, 22.5° and 30° angles.
Close the lock lever slowly to assure that
footplate is locked at the desired angle.

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, 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 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
top speed, and then very gradually lower the
blade (Fig. 8).
BEVEL
SC LE
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.
