3.2 FITTING THE CROSS HATCH CUTTER BLADE
The Elcometer 107 is supplied with a cutter blade. Different sizes of
cutting blades are available, see Section 6.1 'Cross Hatch Cutter
Blades' on page en-8, all of which fit the adhesion tester.
To fit a cutter:
1
Use the hexagonal wrench supplied to remove the cutter securing
screw by turning anti-clockwise.
2
Remove the existing cutter (if fitted) and position the new cutter.
3
Re-position and tighten the cutter securing screw.
3.3 CHANGING THE CUTTING EDGE
Each cross hatch cutter blade has a total of 4
cutting edges, labelled 1 to 4.
When a cutting edge becomes worn, simply
rotate the cutting blade by 180° to use the next
cutting edge on that side. Repeat until both
cutting edges are worn.
Remove the cutting blade, turn over and re-fit
(see Section 3.2), to use the cutting edges on
other side.
Note: The ISO/JIS Standard recommends that the cutting
tool is replaced when the top of the blades has flattened to 0.1mm.
