A specialised centre will sharpen the chain using the right tools to ensure minimal removal of material and even sharpness
on all cutting edges. If you sharpen the chain yourself, use special round-section files with the right diameter depending on
the type of chain (see chain maintenance table). You need a certain amount of skill and experience to avoid damaging the
cutting edges.
Sharpening The Chain (continued)
(Refer To Page 20)
WARNING
Make sure the battery is not inserted in its housing.
• Secure the bar firmly, with the chain mounted, in a suitable vice.
• Tighten the chain if it is loose.
• Mount the file in the guide and then insert it in the tooth at a constant angle from the cutting edge.
• Sharpen in a forward motion a few times and repeat this on all the cutting edges facing the same way (right or left).
• To move the chain forward, use the switch to release the brake, then use a screwdriver to make the chain run.
• Turn the bar over in the vice and repeat on all other cutting edges.
• Check that the depth gauge does not stick out further than the inspection instrument and file and projecting parts with
a flat file, rounding off the edge.
• After sharpening, remove all traces of filing and dust and lubricate the chain in an oil bath.
Replace the chain whenever:
• The length of the cutting edges reduces to 5mm or less;
• There is too much play between the links and the rivets.
Bar Maintenance
To avoid asymmetrical wear on the bar, make sure it is turned over periodically.
To keep the bar in perfect working order, proceed as follows:
• Grease the bearings on the nose sprocket (if present) with the syringe.
• Clean the bar groove with the scraper.
• Clean the lubrication holes.
• With a flat file, remove the burr from the edges and level off the guides.
Replace the bar whenever:
• The groove is not as deep as the height of the drive links (which must never touch the bottom):
• The inside of the guide bar is worn enough to make the chain lean to one side.
