Working Advice

Protect saw blades against impact and shock.
Guide the machine evenly and with light feed in
the cutting direction. Excessive feed significant-
ly reduces the service life of the saw blade and
can cause damage to the power tool.
Sawing performance and cutting quality depend
essentially on the condition and the tooth form
of the saw blade. Therefore, use only sharp saw
blades that are suited for the material to be
worked.
Sawing Wood
The correct selection of the saw blade depends
on the type and quality of the wood and whether
lengthway or crossway cuts are required.
When cutting spruce lengthways, long spiral
chips are formed.
Beech and oak dusts are especially detrimental
to health. Therefore, work only with dust extrac-
tion.
Sawing Plastic (PKS 54 CE/PKS 66 CE)
Note: When sawing plastic, especially PVC, long
spiral chips are formed that can be electrostati-
cally charged. This can clog the sawdust ejector
18 and cause the retracting blade guard 13 to
jam. It is best to work with dust extraction.
Guide the switched on power tool against the
workpiece and carefully start the cut. Continue
the cut with low feed and without interruption,
so that the saw teeth do not gum up too quickly.
Sawing Non-ferrous Metals (PKS 54 CE/
PKS 66 CE)
Note: Use only a sharp saw blade that is suitable
for non-ferrous metals. This ensures a clean cut
and prevents blade binding.
Guide the switched on power tool against the
workpiece and carefully start the cut. Continue
the cut with low feed and without interruption.
When sawing profiles, always begin the cut from
the narrow side; when sawing U-profiles, never
start the cut from the open side. Support long
profiles in order to avoid blade binding and kick-
back of the power tool.

Sawing Light Building Materials (Materials
with Mineral Content) (PKS 54 CE/PKS 66 CE)
When sawing light building materials, ob-
serve the statutory provisions and the rec-
ommendations of the material suppliers.
Light building materials may only be sawn dry
and when applying dust extraction. Always work
with the guide rail 29 (accessory).
The vacuum cleaner must be approved for the
extraction of masonry dust. Bosch provides suit-
able vacuum cleaners.
Sawing with Parallel Guide (see figure D)
The parallel guide 12 enables exact cuts along a
workpiece edge and cutting strips of the same
dimension.
Loosen wing bolt 9 and slide the scale of the
parallel guide 12 through the guide in the base
plate 15. Adjust the desired cutting width as the
scale setting at the respective cutting mark 11
or 10; see Section "Cutting Marks". Tighten
wing bolt 9 again.
Sawing with Auxiliary Guide (see figure E)
For sawing large workpieces or straight edges, a
board or strip can clamped to the workpiece as
an auxiliary guide; the base plate of the circular
saw can be guided alongside the auxiliary guide.
Sawing with Guide Rail (see figure F)
The guide rail 29 is used to carry out straight
cuts.
The adhesive coating prevents the guide rail
from slipping and protects the surface of the
workpiece. The coating of the guide rail allows
the circular saw to glide easily.
The rubber lip on the guide rail acts as a splinter
guard that prevents fraying or tearing out of the
surface when sawing wooden materials. For
this, the teeth of the saw blade must face direct-
ly against the rubber lip.
The guide rail 29 must not extend beyond the
face side of the workpiece where the cut is to
be started.
The guide-rail adapter 28 is required for working
with the guide rail 29. The guide-rail adapter 28
is mounted in the same manner as the parallel
guide 12.
