washer and bolt, then fasten the nut (see Fig.12: 1-bolt; 2-washer; 3-spacer;
4-nut)
Check the blade and the fasteners for looseness, cracking, or bending.
2. Check the cutting edges and reform with a flat file.
3. The blades assembly is designed to automatically compensate for any
play between the blades.
4. Regularly check that blade bolts are well tightened.
You do not need to adjust the gap (Fig. 13) between upper blade and lower
blade as this product is designed to have optimal gap when it is properly set
up.

Always keep the file or sharpener at an angle of 45° to the blade
(fig.14), and:
- Always grind in the direction of the cutting edge;
- Note: files only cut in one direction, lift the file from the blade when
returning to start a new pass;
- Remove all burr from the edge of the blade with a slip stone;
Remove as little material as possible;
- Before re-mounting the sharpened blade, remove filing remnants
and then apply grease (Fig.15)
Warning! Do not attempt to sharpen a damaged, cracked blade;
change it.
