WARNING:
Always wear protective
gloves during maintenance operations. Do not
carry out maintenance when the engine is hot.
The pitch of the chain
(Fig. 24)
is 9.53 mm х 1.27 mm
(3/8” LoPro x .050”).
Sharpen the chain using protective gloves and a
round file of Ø4.8 mm (not included in the kit).
Fig. 24
Always sharpen the cutters only with outward strokes
(Fig. 25)
observing the values given in
Fig. 24
.
After sharpening, the cutting links must all have the
same width and length.
WARNING:
A sharp chain produces
well-defined chips. When your chain starts to
produce sawdust, it is time to sharpen.
After every 3–4 times the cutters have been sharp-
ened you need to check the height of the depth gaug-
es and, if necessary, lower them using the flat file and
template (not included in the kit), then round off the
front corner
(Fig. 26)
.
WARNING:
Proper adjustment of
the depth gauge is as important as proper
sharpening of the chain.

Guide bar
– The bar should be reversed every 8
working hours to ensure uniform wear.
Keep the bar groove and lubrication hole clean us-
ing the bar groove cleaner (not included in the kit)
(Fig. 27)
.
Check the bar rails frequently for wear and, if neces-
sary, remove the burs and square-up the rails using
the flat file
(Fig. 28)
.
WARNING:
Never mount a new chain
on a worn sprocket or self-aligning ring.

bar wear
– Turn guide bar frequently at regular in-
tervals (for example, after 8 hours of use), to ensure
even wear on top and bottom of bar.
oil passages
– Oil passages on the bar should be
cleaned to ensure proper lubrication of the bar and
chain during operation.
NotE.
The condition of the oil passages can be eas
-
ily checked. If the passages are clear, the chain will
automatically give off a spray of oil within seconds of
starting the saw. Your saw is equipped with an auto-
matic oiler system.
cHAIN mAINtENANcE
chain tension:
Check the chain tension frequently and adjust as of-
ten as necessary to keep the chain snug on the bar,
but loose enough to be pulled around by hand.
breaking in a new saw chain:
A new chain and bar will need chain readjustment af-
ter as few as 5 cuts. This is normal during the break-in
period, and the interval between future adjustments
will begin to lengthen quickly.
WARNING:
Never have more than 3
links removed from a loop of chain. This could
cause damage to the sprocket.
chain lubrication:
Always make sure the automatic oiler system is work-
ing properly. Keep the oil tank filled with SPARKY
chain, bar and sprocket oil.
Adequate lubrication of the bar and chain during cut
-
ting operations is essential to minimize friction with
