After longer periods of work at low stroke rate,
the machine can heat up considerably. Remove
the saw blade from the machine and allow the
machine to cool down by running it for approx.
3 minutes at maximum stroke rate.

Working Advice

When working small or thin work pieces, al-
ways use a sturdy support or a saw table
(accessory).
While working, hold the machine by the handle
4 and guide it alongside the desired cutting line.
For precise cuts and quiet running, guide the
machine additionally with the other hand by the
plastic cap 1.
Contact Protector
The contact protector 16 attached to the casing
prevents accidental touching of the saw blade
during the working procedure and may not be
removed.
Sawing Thick Wood
For straight cuts in thick wood, please observe
the following recommendations:
– Switch on Precision Control for lateral guid-
ance of the saw blade (see "Precision Con-
trol", page 24).
– Use Bosch saw blades marked with "Preci-
sion for Wood".
– Adjust the precise mitre angle using an angle
measurer.
– Saw applying only low feed. Orbital action
and stroke ensure sufficient working proc-
ess.
– Always guide the machine resting firmly
against the parallel guide 27 or an auxiliary
guide rail. Avoid lateral pressure on the han-
dle 4 to prevent tilting of the machine.
– While sawing, hold the machine with one
hand by the handle 4 and with the other hand
by the plastic cap 1.
Bosch Power Tools
Plunge Cutting (see figures I – J)
Plunge cuts may only be applied to soft
materials, such as wood, gypsum plaster
boards, etc.!
Use only short saw blades for plunge cutting.
Plunge cutting is possible only with the mitre
angle set at 0°.
Place the machine with the front edge of the
base plate 9 on to the workpiece without the
saw blade 15 touching the workpiece and
switch on. For machines with stroke rate con-
trol, select the maximum stroke rate. Firmly
hold the machine against the workpiece and by
tilting the machine, slowly plunge the saw blade
into the workpiece.
When the base plate 9 fully lays on the workpiece,
continue sawing along the desired cutting line.
Parallel Guide with Circle Cutter (Accessory)
For cuts using the parallel guide with circle cut-
ter 27 (accessory), the thickness of the material
must not exceed a maximum of 30 mm.
Parallel Cuts (see figure K): Loosen the locking
screw 26 and slide the scale of the parallel guide
through the lead 25 in the base plate. Set the
desired cutting width as the scale value on the
inside edge of the base plate. Tighten the lock-
ing screw 26.
Circular Cuts (see figure L): Set the locking
screw 26 to the other side of the parallel guide.
Slide the scale of the parallel guide through the
lead 25 in the base plate. Drill a hole in the work-
piece centred in the section to be sawn. Insert
the centring tip 28 through the inside opening of
the parallel guide and into the drilled hole. Set
the radius as the scale value on the inside edge
of the base plate. Tighten the locking screw 26.
Coolant/Lubricant
When sawing metal, coolant/lubricant should be
applied alongside cutting line because of the
material heating up.
