NOTE:
The condition of the oil passages can be easily
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 automatic
oiler system.

CHAIN MAINTENANCE
CHAIN TENSION:
Check the chain tension frequently and adjust as often
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 after
as few as 5 cuts. This is normal during the break-in
period, and the interval between future adjustments will
begin to lengthen quickly.
CHAIN LUBRICATION:
Always make sure the automatic oiler system is working
properly. Keep the oil tank filled with Talon Chain, Bar
and Sprocket Oil.
Adequate lubrication of the bar and chain during cutting
operations is essential to minimize friction with the guide
bar.
Never starve the bar and chain of lubricating oil. Running
the saw dry or with too little oil will decrease cutting
efficiency, shorten saw chain life, cause rapid dulling of
chain, and lead to excessive wear of bar from
overheating. Too little oil is evidenced by smoke or bar
discoloration.
CHAIN SHARPENING:
Chain sharpening requires special tools to ensure that
cutters are sharpened at the correct angle and depth.
For the inexperienced chain saw user, we recommend
that the saw chain be professionally sharpened by the
nearest professional Service Center. If you feel
comfortable sharpening your own saw chain, special
tools are available from the professional Service Center.

WARNING:
Never have more than 3 links
removed from a loop of chain. This could cause
damage to the sprocket.

REMOVING A UNIT FROM STORAGE
1.
Remove spark plug.
2.
Pull starter rope briskly to clear excess oil from com-
bustion chamber.
3.
Clean and gap spark plug or install a new spark plug
with proper gap.
4.
Prepare unit for operation.
5.
Fill fuel tank with proper fuel / oil mixture. See
FUEL
AND LUBRICATION
Section.
Lubrication of the sprocket tip is recommended after 10
hours of use or once a week, which ever occurs first.
Always thoroughly clean guide bar sprocket tip before
lubrication.
TOOLS FOR LUBRICATION:
The Lube Gun (optional) is recommended for applying
grease to the guide bar sprocket tip. The Lube Gun is
equipped with a needle nose tip which is necessary for the
efficient application of grease to the sprocket tip.
TO LUBRICATE SPROCKET TIP:
1.
Move the STOP switch down.
NOTE:
It is not necessary to remove the saw chain to
lubricate the guide bar sprocket tip. Lubrication can be
done on the job.
2.
Clean the guide bar sprocket tip.
3.
Using the Lube Gun (optional), insert needle nose
into the lubrication hole and inject grease until it
appears at outside edge of sprocket tip (Fig .23).
4.
Rotate saw chain by hand. Repeat lubrication proce-
dure until the entire sprocket tip has been greased.
GUIDE BAR MAINTENANCE:
Most guide bar problems can be prevented merely by
keeping the chain saw well maintained.
Insufficient guide bar lubrication and operating the saw
with chain that is TOO TIGHT will contribute to rapid bar
wear.
To help minimize bar wear, the following guide bar main-
tenance procedures are recommended.
CHAIN SHARPENING
- The pitch of the chain (Fig. 24) is
3/8” LoPro x .050”.
Sharpen the chain using protective gloves and a round file
of ø5/32” (3.97mm).
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.
After every 3-4 times the cutters have been sharpened
you need to check the height of the depth gauges and, if
necessary, lower them using a flat file and template, then
round off the front corner. (Fig. 26)
GUIDE BAR
- The bar should be reversed every 8 work-
ing hours to ensure uniform wear.
Keep the bar groove and lubrication hole clean using a
bar groove cleaner. (Fig. 27)
Check the bar rails frequently for wear and, if necessary,
remove the burs and square-up the rails using the flat file.
(Fig. 28)
BAR WEAR
- Turn guide bar frequently at regular
intervals (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.
CAUTION
: The sprocket tip on your new saw has
been pre-lubricated at the factory. Failure to
lubricate the guide bar sprocket tip as explained
below will result in poor performance and seizure,
voiding the manufacturer’s warranty.
WARNING:
Wear heavy duty work gloves
when handling the bar and chain.
Fig. 23
WARNING
: Always wear protective gloves dur-
ing maintenance operations. Do not carry out
maintenance when the engine is hot.
Fig. 24
WARNING
: A sharp chain produces well-
defined chips. When your chain starts to produce
sawdust, it is time to sharpen.
Fig. 26
Fig. 25
WARNING
: Proper adjustment of the depth
gauge is as important as proper sharpening of
the chain.
WARNING
: Never mount a new chain on a
worn sprocket or self-aligning ring.
