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. 15).
Branches under tension should be cut from the bottom
up to avoid binding the chain saw.
•
BUCKING
Bucking is cutting a fallen log into lengths. Make sure
you have a good footing and stand uphill of the log when
cutting on sloping ground. If possible, the log should be
supported 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. 16A).
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. 16B).
3.
Log supported on both ends: First, overbuck 1/3
diameter of log to avoid splintering. Second,
underbuck to meet first cut and avoid pinching
(Fig. 16C).
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 supporting logs. Be sure the log being cut is
securely supported.
•
BUCKING USING A SAWHORSE
For personal safety and ease of cutting, the correct
position for vertical bucking is essential (Fig. 17).
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.
All chain saw service, other than items listed here in
your user manual maintenance instructions, should be
performed by a professional.
•
PREVENTIVE MAINTENANCE
A good preventive maintenance program of regular
inspection and care will increase life and improve
performance of your Talon chain saw. This maintenance
checklist is a guide for such a program.
Cleaning, adjustment, and parts replacement may be
required, under certain conditions, at more frequent
intervals than those indicated.
•
AIR FILTER
TO CLEAN AIR FILTER:
1.
Remove the top cover (A) by loosening the cover
retaining screws. Cover will lift off.
2.
Lift the air filter (B) out of air-box (C) (Fig. 18).
3.
Clean air filter. Wash filter in clean, warm, soapy
water. Rinse in clear, cool water. Air dry completely.

FUEL FILTER
1.
Remove the fuel tank cap.
2.
Bend a piece of soft wire.
3.
Reach into fuel tank opening and hook fuel line.
Carefully pull the fuel line toward the opening until
you can reach it with your fingers.
NOTE: Do not pull hose completely out of tank.
4.
Lift filter (A) out of tank (Fig. 19).
5.
Pull filter off with a twisting motion. Discard filter.
6.
Install new filter. Insert end of filter into tank
opening. Make sure filter sits in bottom corner of
tank. Use a long handle screwdriver to aid in filter
placement if necessary.
7.
Fill tank with fresh fuel / oil mixture. See Section
FUEL AND LUBRICATION. Install fuel cap.
•
SPARK ARRESTER SCREEN (Fig. 20A)
NOTE: A clogged spark arrester screen will dramatically
reduce engine performance.
1.
Remove the 2 bar retaining nuts (A) and loosen the
2 screws (B) that secure the chain brake cover
(Fig. 20A).
2.
Remove the chain brake cover. Remove the 3
screws that hold the muffler to the cylinder. The
muffler will lift off after retaining screws are removed
(Figure 7-4B).
3.
Separate muffler halves (C). Remove the metal
baffles (D) and spacer tubes (E).
4.
Discard the used spark arrester screen and replace
it with a new one (F) (Fig. 20B).
5.
Reassemble the muffler components and install the
muffler to the cylinder. Tighten screws securely.
•
SPARK PLUG
NOTE: For efficient operation of saw engine, spark plug
must be kept clean and properly gapped.
1.
Push STOP switch down.
2.
Disconnect the wire connector (A) from the spark
plug (B) by pulling and twisting at the same time
(Fig. 21).
3.
Remove spark plug with spark plug socket wrench.
DO NOT USE ANY OTHER TOOL.
4.
Reinstall a new spark plug, gapped at .635mm.
•
CARBURETOR ADJUSTMENT
The carburetor was pre-set at the factory for optimum
performance. If further adjustments are necessary,
please take your unit to the nearest professional.
•
STORING A CHAIN SAW
Storing a chain saw for longer than 30 days requires
storage maintenance. Unless the storage instructions
are followed, fuel remaining in the carburetor will evapo-
rate, leaving gum-like deposits. This could lead to diffi-
cult starting and result in costly repairs.
1.
Remove the fuel tank cap slowly to release any
pressure in tank. Carefully drain the fuel tank.
2.
Start the engine and let it run until the unit stops to
remove fuel from carburetor.
3.
Allow the engine to cool (approx. 5 minutes).
4.
Using a spark plug wrench, remove the spark plug.
5.
Pour 1 teaspoon of clean 2-cycle oil into the
combustion chamber. Pull starter rope slowly
several times to coat internal components. Replace
spark plug (Fig. 22).
NOTE: Store the unit in a dry place and away from
possible sources of ignition such as a furnace, gas hot
water heater, gas dryer, etc.

CAUTION: Never operate your saw without
a fuel filter. The fuel filter should be
replaced after each 20 hours of use. Drain
fuel tank completely before changing filter.
