Hammer maintenance:

The correct operation of the hammer:

1. The catcher bar to withstand the surface of concrete, light pressure device, so that the button to relax, relax the pressure when the bullet bar out, hook hanging hammer.

2. The axis of the instrument is always perpendicular to the surface of the concrete and slowly and evenly pressed, until the bullet hammer decoupling impact hammer, the hammer hammer rebound to move the pointer back to a position, the pointer block on the show The value line shows a certain value on the scale that is the rebound value.

3. Keep the instrument movement against the concrete surface to read and record the springback value. If the condition is not conducive to the reading, press the button, lock the movement, move the instrument to read it.

4. Gradually decompression of the instrument, so that the hammer from the instrument out, until the next use.

Hammer maintenance:

The springback should be routinely maintained in any of the following cases:

1. hit more than 2,000 times;

2. When there is doubt about the test value;

3. Steel anvil rate is not qualified;

Routine maintenance methods should meet the following requirements:

1. Remove the hammer after removing the hammer from the hammer and remove the hammer (remove the cushion spring) and the triad (hammering hammer, hammering spring and h the spring)

2. Use gasoline to clean the parts of the movement, especially the center guide rod, the hammer and the hammer and the impact of the hole and the impact of the surface after the guide rod on the thin layer of oil or sewing oil, Parts are not oil;

3. Clean the inner wall of the cabinet, remove the scale, check the finger friction should be between 0.5-0.8N;

4. Do not rotate the tail cover has been fixed on the tightening of the zero screw;

5. Do not make or replace parts;

6. After maintenance should be required to test the rate, the rate should be set to 80 ± 2.

Test of Hammer:

If there is any of the following conditions, the rebound instrument shall be sent to the statutory department for verification. The qualified rebound instrument shall have a certificate of verification:

1. new hammer before opening;

2. Exceed the validity period (valid for six months);

3. Accumulated bombs more than 6000 times;

4. After the regular maintenance of the anvil rate fixed value failed;

5. Serious impact or other damage.
