Sawing Plastic
Note: Sawing plastic, in particular PVC, produces long,
spiral-shaped chips that can be electrostatically charged.
This can lead to the chip ejector (18) becoming clogged.
Therefore, you should not work without dust extraction.
Switch on the power tool and bring it into contact with the
workpiece, sawing it carefully. Then continue working
quickly and without interruption so that the saw teeth do not
become stuck as quickly.
Sawing non-ferrous metal
Note: Only use a sharp saw blade that is suitable for non-fer-
rous metal. This guarantees a clean cut and will prevent the
saw blade from jamming.
Switch on the power tool and bring it into contact with the
workpiece, sawing it carefully. Then continue working with
less feed and without interruption.
For profiles, always begin the cut on the narrow side; for U-
shaped profiles, never begin the cut on the open side. Sup-
port long profiles to prevent the saw blade jamming and the
power tool kicking back.
Sawing lightweight materials (materials containing
minerals)
When sawing lightweight materials, take into account
u
the statutory provisions and recommendations of the
material manufacturers.
Lightweight materials may only be worked on using dry cuts
and with a dust extraction system. Always use the guide rail
(29) (accessory).
The dust extractor must be approved for extracting stone
dust. Suitable dust extractors are available from Bosch.
Sawing with the guide rail (see figure D)
You can use the guide rail (29) to produce straight cuts.
The rubber lip on the guide rail acts as an anti-splinter guard,
which prevents the surface from splintering when sawing
wooden materials. To fulfil this function, the saw blade must
be positioned with its teeth right up against the rubber lip.
Before making the first cut with the guide rail (29), the rub-
ber lip must be adapted to the circular saw used. To do so,
position the guide rail (29) along the entire length of a work-
piece. Set a cutting depth of approx. 9 mm and a right-
angled mitre/bevel angle. Switch on the circular saw and
guide it evenly, pushing it gently in the cutting direction.
The connector (30) can be used to join two guide rails. The
four screws in the connector are used for the purpose of
clamping.
Adjusting the base plate to other guide rails (see figure
E)
The narrow groove integrated into the base plate (7) can be
used for the guide rails shown on the accessories page. To
adjust the base plate to guide rails with a wider guide ring
that are made by other suppliers, remove the plastic insert
(34). Attach the saw to the guide rail and adjust the fitting
accuracy of saw and guide rail as required using the two
knurled screws (35).

Sawing with the parallel guide (see figures F–G)
The parallel guide (14) allows you to make precise cuts
along the edge of a workpiece and cut strips with the same
dimensions.
Slide the guide rods on the parallel guide (14) through the
guides in the base plate (7). Attach the wing bolts (10) on
both sides as shown in the figure, then screw in the wing
bolts(10) without fully tightening them.
Set the required cutting width as the scale value at the re-
spective cut mark (32) or (33) (see "Cut marks (see figure
D)", page 18). Then tighten the wing bolts (10).
Sawing with an auxiliary guide (see figure H)
For working on large workpieces or for cutting straight
edges, you can securely fasten a board or rail to the work-
piece as an auxiliary guide. The circular saw can be guided
along the path of this auxiliary guide with the base plate.

Maintenance and Service

Maintenance and cleaning

Pull the plug out of the socket before carrying out any
u
work on the power tool.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
The protective guard (15) must always be able to move
freely and retract automatically. It is therefore important to
keep the area around the protective guard (15) clean at all
times. Remove dust and chips with a paintbrush.
Non-coated saw blades can be protected against corrosion
using a thin layer of acid-free oil. Remove the oil again before
sawing as failure to do so will stain the wood.
Resin or glue residue on the saw blade has a detrimental ef-
fect on the quality of the cut. You should therefore clean saw
blades straight after use.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.
