Bosch 1590 EVS, Operating/Safety Instructions Manual

Page: 11 / 36

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
jigsaw 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.
When cutting thick wood, use the precision
control button for increased lateral guidance
of the saw blade.
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. 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. Start the motor,
and then very gradually lower the blade.
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.
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. Do not try
to plunge cut into hard materials such as
steel.
CIRCLE AND PARALLEL CUTTING GUIDE
(Not included, available as accessory)
This accessory is available at an extra cost. It
is used for fast and accurate straight and
circle cutting (Fig.12).
PARALLEL CUTTING
1. Insert bar of guide through lock knob
clamp, then through the slots provided in
foot, from either side of foot with the edge
guide facing DOWN (Fig. 12).
2. Hook lock knob clamp onto edge of
footplate, adjust fence to desired width, and
securely tighten lock knob clamp (Fig. 12).
CIRCLE CUTTING
1. Before attaching the guide, draw a circle
and predrill a 13/64” center hole in workpiece.
2. Drill or plunge cut near the circles edge,
turn saw off and disconnect the plug from
power source.
3. Attach guide to saw with edge guide facing
UP as shown (Fig. 13).
4. Remove guide pin from end of guide, push
pin through hole provided in guide, then into
center hole of workpiece.
5. Measure the distance from the selected
hole to the blade to be equal to the circle
radius.
6. Insert plug into power source, hold the saw
firmly, squeeze trigger and slowly push the
saw forward. To make a hole, cut from inside
the circle; To make wheels or discs, cut from
the outside.
Cutting Tip: Cut slowly so the blade will stay
straight in the cut. Place small wedges in the
cut as shown in Fig. 13, to keep the inner
circle from spreading when near the end of
the cut.
