MAINTENANCE
SAW CHAIN MAINTENANCE - SHARPENING THE CHAIN (continued)
• 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 - Fig. 17, page 22
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.
SPROCKET - Fig. 18, page 22
• The damaged sprocket will cause premature damage or wear of saw chain.
• When the sprocket has worn out 0.5mm or more replace it.
• Check sprocket when you install new chain.
• Replace it if worn.
WARNING
The characteristic data of the chain and bar homologated for this machine are showing in the "EC Conformity Statement"
that accompanies same machine. Do not use other types of chains or bars for safety reasons. The table gives the
sharpening data for different types of chains, but this does not mean you can use different chains from the homologated
one.
