7 .2 Sharpening test
WARNING Stop the machine immediately if it does not work correctly!
Always do a sharpening test:
• when the machine is new,
• to learn how to use the machine, or
• if the chain is not sharpened as expected .
Recommendation: Use an old chain for the test .
1 . Insert a test chain into the machine and sharpen it according to the instructions in section 5, “Operation” .
2 . Test the functions of the machine and study its motions .
3 . Make sure that:
• the right (outer) and left (inner) cutters are sharpened to even lengths . Use a slide-gauge to measure . If they
are uneven, see section 5 .2 .9, “Set the grinding length” .
• the grinding depth on the chain is deep enough . If the grinding wheel is worn, it needs to be adjusted, see
section 5 .2 .8, “Center the grinding disc” . If it needs to be changed, see section 6 .3, “Change the grinding
wheel and fit the grinding wheel guard” .
4 . Repeat the sharpening test until you see satisfactory test results, and the machine is running trouble-free .
5 . Remove the test chain .
