Practical advice

With the Bluetooth® Low Energy Module GCY 42, the
u
power tool is equipped with a radio interface. Local
operating restrictions, e.g. in aircraft or hospitals,
must be observed.
In areas where the Bluetooth® wireless technology is
u
not allowed to be used, the Bluetooth® Low Energy
Module GCY 42 and the button cell must be removed.
The width of cut varies depending on the saw blade used.
Protect saw blades against shock and impact.
Guide the power tool evenly, pushing it gently in the cutting
direction. Applying too much pressure to the power tool
when moving it in the cutting direction significantly reduces
the service life of the application tools and can damage the
power tool.
The sawing performance and the quality of the cut essen-
tially depend on the condition and the tooth shape of the
saw blade. This is why you should only use sharp saw blades
that are suitable for the material being machined.
Sawing wood
Choosing the right saw blade depends on the wood type,
wood quality and whether cuts with or against the grain are
required.
Making cuts in spruce with the grain produces long, spiral-
shaped chips.
Beech and oak dust is especially detrimental to health.
Therefore, work only with dust extraction.
Sawing with a parallel guide (see figure F)
The parallel guide (11) allows you to make precise cuts
along the edge of a workpiece and cut strips with the same
dimensions.
Slide the guide rod of the parallel guide (11) through the
guide into the base plate (13). Mount the parallel guide (11)
with the wing bolt (6).
Sawing with an auxiliary guide (see figure G)
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.
Sawing with the guide rail (see figures H – I)
GKS 18V-68 GC
You can use the guide rail (41) to produce straight cuts.
The adhesive layer prevents the guide rail from slipping and
preserves the surface of the workpiece. The guide rail's coat-
ing allows the power tool to glide more easily.
Place the circular saw directly on the guide rail (41). Fasten
the guide rail (41) to the workpiece using suitable clamping
devices, e.g. screw clamps, so that the narrow side of the
guide rail (41) is facing the saw blade.
The guide rail (41) must not protrude over the edge of
the workpiece being sawn into.
Switch on the power tool and push it gently in the cutting dir-
ection, guiding it evenly.

The connector (43) can be used to join two guide rails. The
four screws in the connector are used for the purpose of
clamping.
The groove (44) is suitable for guide rail systems from Bosch
and Mafell.
The groove (45) is suitable for guide rail systems from Fes-
tool and Makita.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of −20 to
50 °C. Do not leave the battery in your car in the summer, for
example.
Occasionally clean the ventilation slots on the battery using a
soft brush that is clean and dry.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.

Maintenance and Service

Maintenance and Cleaning

Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
The retracting blade guard must always be able to move
freely and retract automatically. It is therefore important to
keep the area around the retracting blade guard 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.
