Maintenance and Repair

Avoid placing the PHT-2000 near locations where it can be exposed to shock, heavy

dust, dampness, oils or

strong magnetic fields.

7.1

Impact Device

•

Using the included brush, clean the guide tube and impact body after it has

performed 1000-2000 tests using the following procedure:

Screw off the support ring and take out the impact body.

Clean the tube by winding the brush counter-clockwise into the tube until it

reaches the bottom and then pull it out. Repeat this procedure 5-6 times.

Replace the impact body and support ring.

Release the impact spring after each test.

Never apply lubrication of any kind to impact body!

7.2

Repair

•

When the tester is calibrated against the Rockwell standard test block and issues

a reading over 1 HRC, it

could

mean the carbide ball is worn out and should be

replaced.
