Speed preselection (GKS 65 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 65 GCE)
Note: 

When sawing plastic, especially PVC, long spiral chips 

are formed that can be electrostatically charged. This can clog 

the sawdust ejector 

15

 and cause the retracting blade guard 

12

 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 (GKS 65 GCE)
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 65 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 

30

 (ac-

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

masonry dust. Bosch provides suitable vacuum cleaners.

Sawing with Parallel Guide (see figure D)

The parallel guide 

11

 enables exact cuts along a workpiece 

edge and cutting strips of the same dimension.
Loosen wing bolt 

7

 and slide the scale of the parallel guide 

11

through the guide in the base plate 

13

. Adjust the desired cut-

ting width as the scale setting at the respective cutting mark 

9

or 

10

; see Section “Cutting Marks”. Tighten wing bolt 

7

 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 aux-

iliary guide.

Sawing with Guide Rail (GKS 65 G / GKS 65 GCE) 

(see figure F)

The guide rail 

30

 is used to carry out straight cuts.

The rubber lip on the guide rail acts as a splinter guard; it pre-

vents fraying of the surface while sawing wooden materials. 

For this, the teeth of the saw blade must face directly against 

the rubber lip.
Prior to the very first cut, the rubber lip must be adapted with 

the guide rail 

30

 to the circular saw being used. For this, place 

the guide rail 

30

 over its complete length on a workpiece. Ad-

just a cutting depth of approx. 9 mm and the saw blade to a ze-

ro degree angle. Switch the circular saw on and guide it uni-

formly and with light feed in the cutting direction.
Two guide rails can be connected to one with use of the con-

nection piece 

31

. Clamping is carried out with the four screws 

located in the connection piece.

Maintenance and Service

Maintenance and Cleaning

f

Before any work on the machine itself, pull the mains 

plug.

f

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.
