4 CARE & MAINTENANCE
The Elcometer 3095 Buchholz Hardness Tester is designed to give
many years reliable service under normal operating and storage
conditions. Store the components of the test set in a dry and clean
place. Avoid contact with solvents.
4.1 Bevelled disc
If the bevelled disc in the indentor tool becomes worn, remove the
black plastic cap on the side of the tool, loosen the screw, rotate
the disc to expose a new sharp edge, re tighten the screw and then
replace the plastic cap. Replacement discs are available as spare
parts - see "Spares & Accessories" on page 11 for ordering
information.
4.2 Supporting pins
At regular intervals check the indentor tool supporting pins for
wear; see "Getting started" on page 3 for details of how to change
and adjust the pins. Replacement pins are available as spare parts
- see "Spares & Accessories" on page 11 for ordering information.
