مطرقة الهدم بوش (Bosch) وزن (11Kg) تعمل بكهرباء (110V) موديل (GSH 11VC)

Key specs: 1,700 W motor, 23 J impact energy, SDS-max chuck, approximately 11 kg weight, variable speed control, anti‑vibration technology reducing vibration by up to about 40%, advanced anti‑restart safety, and a soft‑grip ergonomic design for better control and comfort during long sessions.

Anti‑vibration technology reduces the transfer of vibration to the user, which can significantly lessen hand‑arm fatigue and improve control. This makes extended demolition tasks more manageable and can help you maintain steady, precise operation over longer work periods.

Connect to a suitable 110 V power source, install an SDS‑max bit, and use the variable speed control to adjust the impact rate. Start with a lower speed for delicate or fragile materials and increase for harder substrates like reinforced concrete. Always let the tool reach full speed before applying full-force pressure and maintain a firm, two-handed grip.

This model uses SDS‑max bits. To install: unplug the tool, insert the bit fully into the chuck until it seats, and secure it with the chuck lock if available. Ensure the bit is appropriate for heavy demolition (carbide‑tipped if needed) and check for wear before reuse. Use the appropriate chisel or point for the task at hand and avoid bending or forcing bits.

Common tasks include breaking through reinforced concrete walls and foundations, chipping out old masonry, demolishing floors, removing stubborn blocks, and clearing debris in preparation for new construction or renovations. It’s well suited for professional contractors performing demanding demolition work.

Always wear appropriate PPE: safety glasses or a face shield, hearing protection, heavy‑duty gloves, and a dust mask or respirator as needed. Use both hands to maintain control, secure the workpiece, keep bystanders away, ensure proper ventilation, and avoid loose clothing or jewelry that could get caught. Use anti‑kickback and keep vibration to a minimum by using the anti‑vibration features and proper stance.

Regularly clear dust from vents and the tool body, inspect the bit and chuck for wear, and replace worn components promptly. Store the hammer in a clean, dry place and check power cables for damage before each use. Periodic inspection and cleaning help prevent overheating and prolong tool life.

Consider the workload: if you’re doing heavy, frequent demolition, the GSH 11VC’s high impact energy (23 J), 1,700 W motor, and anti‑vibration features offer strong performance and operator comfort. For lighter tasks or portability, smaller models may be preferable. Compare weight, vibration levels, impact energy, and bit availability across similar models on Fepy to find the best balance for your job.

Select a stable work area, secure the material to prevent movement, and position yourself with a balanced stance. Install a suitable SDS‑max bit, connect to a compatible power source, set the hammer to the desired mode, and perform a brief test on a scrap section to verify control and depth before proceeding to the main task.

Check the power supply and voltage, verify the bit is properly seated, and ensure the chuck is locked and functioning. Inspect for loose accessories or blocked vents, and ensure the anti‑restart feature isn’t preventing startup after a power interruption. If issues persist, stop and consult a service professional.
