Operation

Operating Modes

f

Before any work on the machine itself, pull the mains 

plug.

Adjusting the Cutting Depth (see figure C)

f

Adjust the cutting depth to the thickness of the work-

piece. 

Less than a full tooth of the blade teeth should be 

visible below the workpiece.

Loosen the clamping lever 

26

. For a smaller cutting depth, 

pull the saw away from the base plate 

15

; for a larger cutting 

depth, push the saw toward the base plate 

15

. Adjust the de-

sired cutting depth at the cutting-depth scale. Tighten the 

clamping lever 

26

 again.

The tightening tension of the clamping lever 

26

 can be read-

justed. For this, unscrew the clamping lever 

26

, and screw it 

back again turned offset by at least 30° in anticlockwise direc-

tion.

Adjusting the Cutting Angle

It is best to place the machine on the face side of the blade 

guard 

18

.

Loosen the wing bolts 

8

 and 

16

. Tilt the saw sidewards. Ad-

just the desired measure on the scale 

6

. Tighten the wing 

bolts 

8

 and 

16

 again.

Note: 

For bevel cuts, the cutting depth is smaller than the set-

ting indicated on the cutting-depth scale 

27

.

Cutting Marks

The 0 °  cutting mark (

9

) indicates the position of the saw 

blade for straight cuts. The 45 °  cutting mark (

10

) indicates 

the position of the saw blade for 45 °  cuts without using the 

guide rail.

Starting Operation

f

Observe correct mains voltage! The voltage of the pow-

er source must agree with the voltage specified on the 

nameplate of the machine. Power tools marked with 

230 V can also be operated with 220 V.

Switching On and Off

To 

start

 the machine, 

first

 push the lock-off button for the 

On/Off switch 

2

 and 

then

 press the On/Off switch 

1

 and keep 

it pressed.
To switch off the machine, 

release

 the On/Off switch 

1

.

Note: 

For safety reasons, the On/Off switch 

1

 cannot be 

locked; it must remain pressed during the entire operation.

Reduced starting current (GKS 55 GCE)

The electronic reduced starting current limits the power con-

sumption when switching the tool on and enables operation 

from a 13 ampere fuse.

Constant Electronic Control (GKS 55 GCE)

Constant electronic control holds the speed constant at no-

load and under load, and ensures uniform working perform-

ance.

Speed preselection (GKS 55 GCE)

The required speed can be preselected with the thumbwheel 

3

 (also while running).

The required speed depends on the saw blade being used and 

on the material being worked (see overview of saw blades at 

the end of these operating instructions).

Working Advice

Protect saw blades against impact and shock.
Guide the machine evenly and with light feed in the cutting di-

rection. 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 Plastic (GKS 55 GCE)
Note: 

When sawing plastic, especially PVC, long spiral chips 

are formed that can be electrostatically charged. This can clog 

the sawdust ejector 

17

 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
Note: 

Use only a sharp saw blade that is suitable for non-fer-

rous metals. This ensures a clean cut and prevents blade bind-

ing.
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 bind-

ing and kickback of the power tool.

Sawing Light Building Materials (Materials with Mineral 

Content) (GKS 55 GCE)

f

When sawing light building materials, observe the stat-

utory provisions and the recommendations of the ma-

terial suppliers.

Light building materials may only be sawn dry and when ap-

plying dust extraction. Always work with the guide rail 

29

 (ac-

cessory).
The vacuum cleaner must be approved for the extraction of 

masonry dust. Bosch provides suitable vacuum cleaners.
