2. General Safety Instructions
WARNING: Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.
2.1 Work Area Safety
- Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
- Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.

4.2 Adjusting Cutting Depth
To adjust the cutting depth, loosen the depth adjustment lever, move the base plate to the desired depth, and then firmly tighten the lever. Ensure the blade extends slightly below the workpiece for a clean cut.
4.3 Adjusting Bevel Angle
For angled cuts, loosen the bevel adjustment lever, tilt the saw to the desired angle (up to 45 degrees), and then tighten the lever securely. Always perform a test cut on scrap material to verify the angle.
4.4 Dust Extraction Connection
Connect a suitable dust extraction system to the saw's dust port to minimize airborne dust and maintain a clear view of the cutting line. This improves safety and work quality.
5. Operating Instructions
Always ensure your workpiece is securely clamped before cutting. Never attempt to cut freehand.
5.1 Starting and Stopping
- To start the saw, press the safety lock-off button (if present) and then squeeze the trigger switch.
- Allow the blade to reach full speed before engaging it with the workpiece.
- To stop the saw, release the trigger switch. Wait for the blade to come to a complete stop before setting the tool down.
5.2 Making Straight Cuts
Align the saw's cutting line indicator with your marked cut line. Maintain a firm grip on both the main and auxiliary handles. Apply steady, even pressure, guiding the saw smoothly through the material. Avoid forcing the saw, as this can lead to kickback or damage to the blade.

5.3 Using the Parallel Guide
For accurate rip cuts, attach the parallel guide to the saw's base plate. Adjust the guide to the desired width from the blade and tighten it. This ensures consistent, straight cuts along the length of the material.
6. Maintenance
Regular maintenance ensures the safe and efficient operation of your circular saw.
6.1 Cleaning
- Always unplug the tool before cleaning.
- Clean the ventilation openings regularly to prevent motor overheating.
- Remove sawdust and debris from the base plate, blade guard, and motor housing using a brush or compressed air.
6.2 Blade Care
Inspect the saw blade before each use for sharpness, cracks, or missing teeth. A dull or damaged blade can cause kickback and poor cut quality. Replace damaged blades immediately.
6.3 Carbon Brush Replacement
The Bosch GKS 150 features an easy system for carbon brush replacement. When the motor performance decreases or sparks become excessive, it may be time to replace the carbon brushes. Refer to the service diagram or contact an authorized service center for detailed instructions.
