Be ready to stop the machine if something goes wrong during trial sharpening.

Check that the grinding wheel is not cracked and that it is securely fixed to the spindle. Stop the grinding wheel immediately if abnormal vibrations occur.

TRIAL SHARPENING

Test the various functions of the machine and study its motions. Always stop the machine when the grinding head reaches its uppermost position. The chain rulers are then “unlocked” and the chain is free. When you have done a trial run with the machine and feel familiar with it, you can put in a chain. Now test-sharpen a chain, following the instructions in the section Sharpening cutting links. In the interest of safety, use an old chain.
