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. 20).
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.
WARNING: Always wear protective gloves
during maintenance operations. Do not carry
out maintenance when the engine is hot.
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 sharp-
ening your own saw chain, special tools are available from
the professional Service Center. For non-experienced
users of the chain saw, we recommend to have thechain
sharpened by a specialist in any authorised service.
WARNING: When having wrong sharpened
chain, there may occur a higher danger of
kickback.
1. To sharpen the saw chain, use the suitable sharpen-
ing tools:
- Round chain file ø5/32" (4mm).
- File leading
- Chain measuring calibre.
These tools can be bought in any specialsed stores.
2. To gain well shaped sawdust particles, use sharp
chain. If there appears wooden powder, you must
sharpen the saw chain.
WARNING: All cutting teeth must be similarly
long. Different length of the teeth can cause
rough run of the chain or its rupture, as well.
3. Minimum length of the teeth must be 4mm. If they are
shorter, remove the saw chain.
4. Angles, which the teeth are under, must be followed.
5. To sharpen the chain basically, make 2 to 3 pulls of
the file from the inside out.
WARNING: After 3 to 4 of your sharpening of
the cutting teeth, havve the saw chain sharp-
ened in any authorised service. They will
sharpen the depth limiter as well, which pro-
vides the distance.
CHAIN SHARPENING - The pitch of the chain (Fig. 21) is
3/8" LoPro x .050".
Sharpen the chain using protective gloves and a round file
of ø5/32" (4mm).
Always sharpen the cutters only with outward strokes (Fig.
22) observing the values given in Fig. 21.
Fig. 21
WARNING: A sharp chain produces well-
defined chips. When your chain starts to pro-
duce sawdust, it is time to sharpen.
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 the flat file and template sup-
plied optional, then round off the front corner. (Fig. 23)
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 work-
ing hours to ensure uniform wear.
Keep the bar groove and lubrication hole clean using a bar
groove cleaner (optional). (Fig. 24)
Check the bar rails frequently for wear and, if necessary,
remove the burs and square-up the rails using a flat file.
(Fig. 25)
WARNING: Never mount a new chain on a
worn sprocket or self-aligning ring.

BAR WEAR - Turn guide bar frequently at regular
vals (for example, after 5 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 easily
checked. If the passages are clear, the chain will auto-
matically give off a spray of oil within seconds of starting
the saw. Your saw is equipped with an automatic oiler sys-
tem.
• 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.
PROBLEM
Unit won't start or starts but will
not run.
Unit starts, but engine has low
power.
Engine hesitates.
No power under load.
Runs erratically.
Smokes excessively.
WARNING: Never have more than 3 links
removed from a loop of chain. This could
cause damage to the sprocket.
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,
i F . g 2 5
and the interval between future adjustments will begin to
lengthen quickly.
inter- 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 effi-
ciency, 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.
