Maintenance and Repair
Avoid placing the MET near locations where it can be exposed to shock, heavy dust, dampness, strong
magnetic fields and any form of lubricious fluids.
Battery Replacement:
•
Remove two rubber plugs on the back side Bottom half of the MET-U1A. Use the supplied hex
wrench to loosen the two hex screws. Lift the metal battery cover off to expose the 4-AA
batteries. It is recommended that you replace the batteries with a high quality NiMh set of
rechargeable batteries. Standard AA batteries can also be used but life expectancy will not be
very long. Pay careful attention to the polarity when installing new batteries. Please be sure and
dispose of the NiMh batteries properly and according to local recycling laws.

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 or tube!
