Quick guide from the manual
The Bosch GKT 18V-52 GC Professional is a cordless plunge circular saw designed for straight and miter cuts in wood, light building materials, and plastics. It is not intended for cutting ferrous metals. The tool features Bluetooth connectivity for data transfer and settings adjustment via the Bosch Toolbox app.
Device Description
Key components include the on/off switch, lock-off button, saw blade change lever, auxiliary handle, cutting depth scale, and user interface for speed preselection and status monitoring.
Assembly
Before any work, remove the battery. Use protective gloves when handling the saw blade. Ensure the saw blade's rotational direction matches the arrow on the protective guard. Tighten the clamping bolt to 6–9 Nm.
Operation
Adjust the cutting depth to the workpiece thickness (material thickness + tooth height). For miter cuts, loosen the wing bolts, set the angle on the scale, and retighten. The tool features constant electronic control for uniform performance and an ECO mode to extend battery life.
Maintenance and Cleaning
Keep the tool and ventilation slots clean. Ensure the protective guard moves freely and closes automatically. Regularly clean the chip ejector and dust/chip bag. Protect non-coated saw blades with a thin layer of acid-free oil.
Safety
Always wear personal protective equipment, including eye protection and a dust mask. Keep hands away from the cutting area. Support large panels to minimize the risk of kickback. Do not use the tool stationarily.
Troubleshooting
If the status indicator shows critical temperature or low battery, run the tool at no load to cool down or replace/charge the battery. If the indicator flashes red, the restart protection has been triggered; turn the tool off and on again.
