Tips: Precautions when using rotary hammer.

1. After staring the rotary hammer, run it without load for a period of time, check and confirm that the mechanical linkage is flexible and unimpeded. Do not use excessive force when working.
2. Hold handle firmly when operating rotary hammer. Use moderate force and avoid shaking. If the speed drops sharply, reduce force to prevent the motor from overloading.
3. Pay attention to avoid the steel bars in concrete during operation.
4. Rotary hammer is a 40% intermittent work system, it should not be used continuously for a long time.
5. When the working aperture is more than 25mm, a stable working platform should be set up with guardrails around.
6. Pay attention to the sound and temperature rise during operation, and immediately stop the machine for inspection if abnormality is found.
7. When operating rotary hammer, do not touch the cutting tools, molds and grinding wheels with hands. If it is found to be blunt or damaged, stop it immediately for repair or replacement, and then continue to work.
