MAINTENANCE AND STORAGE
same way (right or left).
– Turn the bar over in the vice and repeat on all the
other cutting edges.
– Check that the limiter tooth does not stick out
further than the inspection instrument and file
any 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 5
mm or less;
– There is too much play between the links and
the rivets.

8. EMPTYING AND FLUSHING
THE OIL TANK
(Only if organic oil is used for the chain)
The use of some types of organic oil may cause
deposits or fouling after a certain period of use.
If this happens, before leaving the machine unu-
sed for a long period of time:
– disassemble the chain and the bar;
– empty the oil tank;
– pour a specific liquid cleanser in the tank, to
about half the maximum level;

7. BAR MAINTENANCE (Fig. 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
pre sent) with the syringe.
– Clean the bar groove with the scraper.
– Clean the lubrication holes.
– With a flat file, remove 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 is worn enough to make
the chain lean to one side.
