Starting Operation

Inserting the battery



Use only original Bosch lithium ion batteries with the 

voltage listed on the nameplate of your power tool. 

Using other batteries can lead to injuries and pose a fire 
hazard.

Insert the charged battery 

3

 from the front into the base of 

the power tool. Push the battery completely into the base un-
til the red stripe can no longer be seen and the battery is se-
curely locked.

Switching On and Off

To 

start

 the machine, 

first

 push the lock-off button for the 

On/Off switch 

1

 and 

then

 press the On/Off switch 

2

 and keep 

it pressed.

To 

switch off

 the machine, release the On/Off switch 

2

.

Note: 

For safety reasons, the On/Off switch 

2

 cannot be 

locked; it must remain pressed during the entire operation.

To save energy, only switch the power tool on when using it.

Run-on Brake

An integrated run-on brake reduces the run-on period of the 
saw blade after switching off the machine.

Protection Against Deep Discharging

The Lithium-Ion battery is protected against deep discharging 
by the “Electronic Cell Protection (ECP)”. When the battery is 
empty, the machine is switched off by means of a protective 
circuit: The inserted tool no longer rotates.

Working Advice

Protect saw blades against impact and shock.

Guide the machine evenly and with light feed in the cutting 
direction. Excessive feed significantly 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. There-
fore, 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 extraction.

Sawing with Parallel Guide (see figure D)

The parallel guide 

8

 enables exact cuts along a workpiece 

edge and cutting strips of the same dimension.

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 aux-
iliary guide.

Sawing with Guide Rail (see figure G)

The guide rail 

33

 is used to carry out straight cuts.

Note: 

Use the guide rail 

33

 only for right-angled cuts. When 

using for mitre cuts, the guide rail 

33

 can become damaged.

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.

Place the circular saw directly onto the guide rail 

33

. Fasten 

the guide rail 

33

 with suitable clamping devices, e. g., screw 

clamps, on the workpiece in such a manner that the narrow 
leg of the guide rail 

33

 faces toward the saw blade.

The guide rail 33 must not extend beyond the face side of 

the workpiece where the cut is to be started.

Switch the machine on and guide it in the cutting direction ap-
plying moderate and steady feed.

Two guide rails can be connected to one with use of the con-
nection piece 

34

. Clamping is carried out with the four screws 

located in the connection piece.

Recommendations for Optimal Handling of the Battery

Protect the battery against moisture and water.

Store the battery only within a temperature range between 
0 ° C and 50 ° C. As an example, do not leave the battery in the 
car in summer.

Occasionally clean the venting slots of the battery using a soft, 
clean and dry brush.

A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.

Observe the notes for disposal.

Maintenance and Service

Maintenance and Cleaning



Before any work on the machine itself (e. g. mainte-

nance, tool change, etc.) as well as during transport 

and storage, remove the battery from the power tool. 

There is danger of injury when unintentionally actuating 
the On/Off switch.



For safe and proper working, always keep the machine 

and ventilation slots clean.

The retracting blade guard must always be able to move freely 
and retract automatically. Therefore, always keep the area 
around the retracting blade guard clean. Remove dust and 
chips by blowing out with compressed air or with a brush.

Saw blades that are not coated can be protected against cor-
rosion with a thin coat of acid-free oil. Before use, the oil must 
be removed again, otherwise the wood will become soiled.

Resin and glue residue on the saw blade produces poor cuts. 
Therefore, clean the saw blade immediately after use.

If the machine should fail despite the care taken in manufac-
turing 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 in-
clude the 10-digit article number given on the type plate of 
the machine.
