Here's how to use the rebound hammer:
Hold the bounce lever against the surface of the concrete, press the instrument lightly, release the button, and when the pressure is released, the bounce lever is extended, and the hook is hung with the bounce hammer.
The axis of the instrument is always perpendicular to the surface of the concrete and the pressure is applied slowly and evenly, and when the rebound of the hammer is driven to move backward to a certain position after the hammer is unhooked and the impact of the impact lever, the value of the pointer block shows a certain value on the scale of the rebound value.
Allow the instrument movement to continue to press against the concrete surface to take readings and record the springback value. If the conditions are not favourable for reading, press a button to lock the movement and move the instrument to another place for reading.
Gradually depressurize the instrument so that the lever sticks out of the instrument for the next use.
In the process of using the rebound hammer, pay attention to the following:
After the use of the rebound hammer is completed, it should be put into the rebound tester box in time to avoid dust entering the inside of the rebound hammer.
Do not disassemble and assemble the rebound hammer at will to avoid affecting the service life and accuracy.
It is best to maintain the rebound hammer regularly, and after using it for a period of time, it can be wiped with a dry cloth to keep it clean.
The pointer shaft of the rebound hammer must not be greased, mainly to keep the friction constant.
