Vertical Cutting; Bar / Chain Maintenance; Chain Installation) - Talon AC210516 User Manual

FELLING CUT:
1. Use wooden or plastic wedges (G) to prevent binding
the bar or chain (H) in the cut. Wedges also control
felling (Fig. 10C).
2. When diameter of wood being cut is greater than the
bar length, make 2 cuts as shown (Fig. 10D).
WARNING: As the felling cut gets close to
the hinge, the tree should begin to fall. When
tree begins to fall, remove saw from cut,
unplug, put chain saw down, and leave area
along retreat path (Fig. 10A).

• LIMBING
Limbing a tree is the process of removing the branches
from a fallen tree. Do not remove supporting limbs (A)
until after the log is bucked (cut) into lengths (Fig. 11).
Branches under tension should be cut from the bottom up
to avoid binding the chain saw.
WARNING: Never cut tree limbs while stand-
ing on tree trunk.

• BUCKING
Bucking is cutting a fallen log into lengths. Make sure you
have a good footing and stand uphill of the log when cut-
ting on sloping ground. If possible, the log should be sup-
ported so that the end to be cut off is not resting on the
ground. If the log is supported at both ends and you must
cut in the middle, make a downward cut halfway through
the log and then make the undercut. This will prevent the
log from pinching the bar and chain. Be careful that the
chain does not cut into the ground when bucking as this
causes rapid dulling of the chain.
When bucking on a slope, always stand on the uphill side.
1. Log supported along entire length: Cut from top
(overbuck), being careful to avoid cutting into the
ground (Fig. 12A).
2. Log supported on 1 end: First, cut from bottom
(underbuck) 1/3 diameter of log to avoid splintering.
Second, cut from above (overbuck) to meet first cut
and avoid pinching (Fig. 12B).
3. Log supported on both ends: First, overbuck 1/3
diameter of log to avoid splintering. Second,
buck to meet first cut and avoid pinching
12C).
NOTE: The best way to hold a log while bucking is to use
a sawhorse. When this is not possible, the log should be
raised and supported by the limb stumps or by using sup-
porting logs. Be sure the log being cut is securely sup-
ported.
• BUCKING USING A SAWHORSE
For personal safety and ease

VERTICAL CUTTING:

A. Hold the saw firmly with
both hands and keep the
saw to the right of your
body while cutting.
B Keep the left arm as
straight as possible.
C. Keep weight on both feet.

CAUTION: While the saw is cutting, be sure
the chain and bar are being properly
cated.

BAR / CHAIN MAINTENANCE

• GUIDE BAR MAINTENANCE
WARNING: Ensure that the power cord is
disconnected before performing any mainte-
nance on your saw.
Proper maintenance of the guide bar, as explained in
this section, is essential to keep your saw in good
working order.
SPROCKET TIP LUBRICATION:
(For units supplied with sprocket tip guide bars only.)
CAUTION: Failure to lubricate the guide bar
sprocket tip as explained below will result in
poor performance and seizure, voiding the
manufacturer's warranty.
Lubrication of the sprocket tip is recommended after each
saw use. Always thoroughly clean the guide bar sprocket
tip before lubrication.
Tool for lubrication: Talon Lube Gun (disposable)
This grease gun is designed to fit the small lubrication
point on the guide bar.
The disposable Lube Gun is packed with grease.
WARNING: Wear heavy duty work gloves
when performing this application to reduce
risk of personal injury.

To Lubricate Sprocket Tip:
1. Unplug the chain saw from the power source.
under-
NOTE: It is not necessary to remove the saw chain to
(Fig.
lubricate the guide bar sprocket tip. Lubrication can be
done on the job.
2. Clean the guide bar sprocket tip.
3. Using disposable Lube gun, insert needle nose into
the lubrication hole and inject grease until it appears
at the outside edge of the sprocket tip (Fig.14).
4. Make sure that the chain brake is deactivated. Rotate
the saw chain by hand. Repeat the lubrication proce-
dure until the entire sprocket tip has been greased.

To Clean Guide Bar Rails:
1. Remove sprocket cover, bar and chain.
2. Using a screwdriver, putty knife, wire brush or other
lubri-
similar instrument, clear residue from the rails on the
guide bar. This will keep the oil passages open to pro-
vide proper lubrication to the bar and chain. (Fig. 15)
3. Reinstall the bar, chain, sprocket cover and bar bolt
retaining nuts. (See Section GUIDE BAR / SAW

CHAIN INSTALLATION).

• GUIDE BAR MAINTENANCE
Most guide bar problems can be prevented merely by
keeping the chain saw well maintained.
Incorrect filing and non-uniform cutter and depth gauge
settings cause most guide bar problems, primarily result-
ing in uneven bar wear. As the bar wears unevenly, the
rails widen, which may cause chain clatter and
culty in making straight cuts.
Insufficient guide bar lubrication and operating the saw
with a chain that is TOO TIGHT will contribute to rapid bar
wear (see Section CHAIN MAINTENANCE INSTRUC-
TIONS).
To help minimize bar wear, the following guide bar main-
tenance is recommended.
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.
BAR GROOVES - Bar grooves (or rails which support and
carry the chain) should be cleaned if the saw has been
heavily used or if the saw chain appears dirty. Rails
should always be cleaned every time the saw chain is
removed.
OIL PASSAGES - Oil passages at bar pad should be
cleaned to ensure proper lubrication of the bar and chain
during operation. This can be done using a soft wire small
enough to insert into the oil discharge hole.
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
system.
• CHAIN MAINTENANCE INSTRUCTIONS
WARNING:
Unless you have experience and specialized training for
dealing with kickback (see Safety Precautions), always
use a low-kickback saw chain, which significantly reduces
the danger of kickback. Low-kickback saw chain does not
completely eliminate kickback. A low-kickback or "safety
chain", should never be regarded as total protection
against injury.
A low-kickback saw chain should always be used in con-
junction with other kickback protection devices such as
the chain brake / Hand Guard furnished with your unit.
Always use a replacement saw chain designed as "low-
kickback" or a saw chain which meets the low-kickback
performance.
A standard saw chain (a chain which does not have the
kickback reducing guard links) should only be used by an
experienced professional chain saw operator.
• What is a Low-Kickback Saw Chain?
A low-kickback saw chain is a chain which has met the
kickback performance requirements of ISO 9518.
By keeping the chain brake and saw chain in good work-
Fig. 15
ing condition and correctly serviced as recommended in
this manual, you will be able to maintain the safety system
of your chain saw over the life of the product.
WARNING: Never remove, modify or make
inoperative any safety device furnished with
your unit. The Chain Brake/Hand Guard and
low-kickback saw chain are major safety
features provided for your protection.
WARNING: Always wear heavy duty
protection work gloves and disconnect the
extension cord when working on the saw
chain.
• 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. (See Section SAW
diffi-
CHAIN TENSION ADJUSTMENT).
• BREAKING IN A NEW SAW CHAIN
A new chain and bar will need 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.
Over a period of time, however, the moving parts of the
inter-
saw chain will become worn, resulting in what is called
CHAIN STRETCH. This is normal. When it is no longer
possible to obtain correct chain tension adjustment, a link
will have to be removed to shorten the chain. See your
Talon Authorized Service Center to have this repair per-
formed.
WARNING: Never have more than 3 links
removed from a loop of chain this could
cause damage to the sprocket.
