Disassembly/Assembly of the Riving Knife

For disassembly of the riving knife 

13

, loosen screw 

25

 and 

remove the riving knife 

13

.

For assembly, insert the riving knife 

13

 and tighten it with the 

screw 

25

. Afterwards, check the adjustment of the riving 

knife as described previously.

Dust/Chip Extraction

f

Before any work on the machine itself, pull the mains 

plug.

f

Dusts from materials such as lead-containing coatings, 

some wood types, minerals and metal can be harmful to 

one’s health. Touching or breathing-in the dusts can cause 

allergic reactions and/or lead to respiratory infections of 

the user or bystanders.

Certain dusts, such as oak or beech dust, are considered 

as carcinogenic, especially in connection with wood-treat-

ment additives (chromate, wood preservative). Materials 

containing asbestos may only be worked by specialists.

– As far as possible, use a dust extraction system suita-

ble for the material.

– Provide for good ventilation of the working place.

– It is recommended to wear a P2 filter-class respirator.

Observe the relevant regulations in your country for the 

materials to be worked.

f

Prevent dust accumulation at the workplace. 

Dusts can 

easily ignite.

Mounting the Extraction Adapter (see figure C)
GKS 85:

Attach the extraction adapter 

26

 onto the sawdust ejector 

17

until it latches. Secure the extraction adapter 

26

 additionally 

with the screw 

27

.

A vacuum hose with a diameter of 35 mm can be connected to 

the extraction adapter 

26

.

GKS 85 G:

Attach the extraction adapter 

26

 onto the sawdust ejector 

17

until it latches. A vacuum hose with a diameter of 35 mm can 

be connected to the extraction adapter 

26

.

f

The extraction adapter may not be mounted when no 

external dust extraction is connected. 

Otherwise the ex-

traction channel can become clogged.

f

Do not connect a dust bag to the extraction adapter. 

Otherwise the extraction system can become clogged.

To ensure optimum extraction, the extraction adapter 

26

must be cleaned regularly.

External Dust Extraction

Connect the vacuum hose 

33

 to a vacuum cleaner (accesso-

ry). An overview for connecting to various vacuum cleaners 

can be found at the end of this manual.
The machine can be plugged directly into the receptacle of a 

Bosch all-purpose vacuum cleaner with remote starting con-

trol. The vacuum cleaner starts automatically when the ma-

chine is switched on.
The vacuum cleaner must be suitable for the material being 

worked.

When vacuuming dry dust that is especially detrimental to 

health or carcinogenic, use a special vacuum cleaner.

Operation

Operating Modes

f

Before any work on the machine itself, pull the mains 

plug.

Adjusting the Cutting Depth (see figure D)

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 

28

. For a smaller cutting depth, 

pull the saw away from the base plate 

14

; for a larger cutting 

depth, push the saw toward the base plate 

14

. Adjust the de-

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

clamping lever 

28

 again.

The tightening tension of the clamping lever 

28

 can be read-

justed. For this, unscrew the clamping lever 

28

, 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 

1

.

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 

29

.

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 

3

 and keep 

it pressed.
To switch off the machine, 

release

 the On/Off switch 

3

.

Note: 

For safety reasons, the On/Off switch 

3

 cannot be 

locked; it must remain pressed during the entire operation.

Reduced starting current

The electronic reduced starting current limits the power con-

sumption when switching the tool on and enables operation 

from a 13 ampere fuse.

Working Advice

Protect saw blades against impact and shock.
