Working Advice
¢ Before any work on the machine itself, pull
the mains plug.
¢ When working small or thin workpieces,
always use a stable support or a saw station
(Bosch PLS 300).
Plunge Cutting (see figure H)
¢ 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 6 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 6 fully lays on the work-
piece, continue sawing along the desired cutting
line.
Parallel Guide with Circle Cutter (Accessory)
For cuts using the parallel guide with circle cut-
ter 21 (accessory), the thickness of the material
must not exceed a maximum of 30 mm.
Remove the "Cut Control" base 10 from base
plate 6. For this, lightly press the base together
and remove it from the guide 17.
Parallel Cuts (see figure I): Loosen the locking
screw 22 and slide the scale of the parallel guide
through the lead 17 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 22.
Circular Cuts (see figure J): Drill a hole (large
enough to accomodate the saw blade) close to
the cutting line within the circle to be sawn.
Work the drill hole with a router or file to ensure
that the saw blade faces flush against the cut-
ting line. Reposition the locking screw 22 on the
other side of the parallel guide. Slide the scale
of the parallel guide throught the lead 17 in the
Bosch Power Tools
base plate. Drill a hole in the centre of the cut-
out to be sawn. Insert the centring tip 23
through the inside opening of the parallel guide
and into the drilled hole. Adjust the radius as
scale value at the inside edge of the base plate.
Tighten the locking screw 22.
Coolant/Lubricant
When sawing metal, coolant/lubricant should be
applied alongside cutting line because of the
material heating up.
Maintenance and Service
Maintenance and Cleaning
¢ Before any work on the machine itself, pull
the mains plug.
¢ For safe and proper working, always keep
the machine and ventilation slots clean.
Clean the saw blade holder regularly. For this,
remove the saw blade from the machine and
lightly tap out the machine on a level surface.
Heavy contamination of the machine can lead to
malfunctions. Therefore, do not saw materials
that produce a lot of dust from below or over-
head.
¢ In extreme conditions, always use dust ex-
traction as far as possible. Blow out ventila-
tion slots frequently and install a residual
current device (RCD). When working metals,
conductive dust can settle in the interior of
the power tool. The total insulation of the
power tool can be impaired.
Lubricate the guide roller 14 occasionally with a
drop of oil.
Check the guide roller 14 regularly. If worn, it
must be replaced through an authorised Bosch
after-sales service agent.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for Bosch power tools.
In all correspondence and spare parts order,
please always include the 10-digit article
number given on the type plate of the machine.
