Maintenance Tips

 

Taber Shear / Scratch Tester

  • When not in operation, remove the scratch or shear tool and place in its protective storage container. The precision cutting edge of both tools are fragile and must be handled with care.
  • The scratch and shear tools will eventually become dull through use and should be replaced on a frequent basis. A magnifier can be used to check the condition of the tool and compared to an extra tool (sold separately) reserved for standardization purposes.
  • To reverse the direction of the turntable rotation for the Model 550 or 551 Shear / Scratch tester, remove the bottom cover and swap the black and red wires on the capacitor.  Click here for instructions.
