TO INSTALL SAW CHAIN:
Always wear heavy duty gloves when handling saw chain
or making saw chain adjustments.
1. Spread chain out in a loop with cutting edges (A) point-
ing CLOCKWISE around loop (Fig. 4A).
2. Slip the chain around the sprocket (B) behind the
clutch (C). Make sure the links fit between the sprock-
et teeth (Fig. 4B).
3. Guide the drive links into the groove (D) and around
the end of the bar (Fig. 4B).
NOTE:
The saw chain may droop slightly on the lower part
of bar. This is normal.
4.
Pull guide bar forward until chain is snug. Ensure all
drive links are in the bar groove.
5. Install the clutch cover making sure the tang is posi-
tioned in the lower hole in the guide bar. Make sure the
chain does not slip off of the bar. Install the bar retain-
ing nut hand tight and follow tension adjustment
instructions in Section
SAW CHAIN TENSION
ADJUSTMENT.
NOTE:
The guide bar retaining nuts are installed only
hand tight at this point because saw chain adjustment is
required. Follow instructions in Section
SAW CHAIN
TENSION ADJUSTMENT.

SAW CHAIN TENSION ADJUSTMENT
Proper tension of saw chain is extremely important and
must be checked before starting, as well as during any
cutting operation.
Taking the time to make needed adjustments to the saw
chain will result in improved cutting performance and pro-
longed chain life.
TO ADJUST SAW CHAIN:
1. Hold nose of guide bar up and turn adjustment screw
(D) CLOCKWISE to increase chain tension. Turning
screw COUNTERCLOCKWISE will decrease amount
of tension on chain. Ensure the chain fits snugly all
the way around the guide bar (Fig. 5).
2. After making adjustment, and while still holding nose
of bar in the uppermost position, tighten the bar
retaining nuts securely. Chain has proper tension
when it has a snug fit all around and can be pulled
around by gloved hand.
NOTE:
If chain is difficult to rotate on guide bar or if it
binds, too much tension has been applied. This requires
minor adjustment as follows:
A.
Loosen the bar retaining nuts so they are finger tight.
Decrease tension by turning the bar adjustment
screw COUNTERCLOCKWISE slowly. Move chain
back and forth on bar. Continue to adjust until chain
rotates freely, but fits snugly. Increase tension by turn-
ing bar adjustment screw CLOCKWISE.
B.
When saw chain has proper tension, hold nose of bar
in the uppermost position and tighten the 2 bar retain-
ing nuts securely.

WARNING
: Always wear heavy duty gloves
when handling saw chain or making saw
chain adjustments.
CAUTION:
A new saw chain stretches,
requiring adjustment after as few as 5 cuts.
This is normal with a new chain, and the
interval between future adjustments will
lengthen quickly.

CHAIN BRAKE MECHANICAL TEST
Your chain saw is equipped with a Chain brake that
reduces possibility of injury due to kickback. The brake is
activated if pressure is applied against brake lever when,
as in the event of kickback, operator’s hand strikes the
lever. When the brake is actuated, chain movement stops
abruptly.
TO TEST CHAIN BRAKE:
1. The CHAIN BRAKE is DISENGAGED (chain can
move) when BRAKE LEVER IS PULLED BACK AND
LOCKED. Be sure the chain bareak latch is in the
OFF position. (Fig. 7A)
2. The CHAIN BRAKE is ENGAGED (chain is stopped)
when brake lever is in forward position and the chain
break latch is in the ON position. You should not be
able to move chain. (Fig. 7B)
NOTE:
The brake lever should snap into both positions. If
strong resistance is felt, or lever does not move into either
position, do not use your saw. Take it immediately to a pro-
fessional Service Center for repair.

FUEL
Use regular grade unleaded gasoline mixed with 2-cycle
engine oil for best results. Use mixing ratios in Section
FUEL MIXING TABLE.
•
MIXING FUEL
Mix fuel with 2 cycle oil in an approved container. Use mix-
ing table for correct ratio of fuel to oil. Shake container to
ensure thorough mix.
•
FUEL AND LUBRICATION
•
FUEL MIXING TABLE
•
RECOMMENDED FUELS
Some conventional petrols are being blended with oxy-
genates such as alcohol or an ether compound to meet
clean air standards. Your Talon engine is designed to oper-
ate satisfactorily on any gasoline intended for automotive
use including oxygenated petrols.
•
CHAIN AND BAR LUBRICATION
Always refill the chain oil tank each time the fuel tank is
refilled.
•
ENGINE PRE-START CHECKS
1.
Fill the fuel tank (A) with correct fuel mixture. (Fig. 8).
2.
Fill the oil tank (B) with correct chain and bar oil (Fig.
8).
3.
Be certain the chain brake is disengaged (C) before
starting unit (Fig. 8).
WARNING:
The purpose of the chain brake
is to reduce the possibility of injury due to
kickback; however, it cannot provide the
intended measure of protection if the saw is
operated carelessly. Always test the chain
brake before using your saw and periodically
while on the job.

FUEL AND LUBRICATION
WARNING:
Never use straight gasoline in
your unit. This will cause permanent engine
damage and void the manufacturer’s warran-
ty for that product. Never use a fuel mixture
that has been stored for over 90 days.
WARNING:
If 2-cycle lubricant other than
Talon Custom Lubricant is to be used, it must
be a premium grade oil for 2-cycle air cooled
engines mixed at a 25:1 ratio. Do not use any
2-cycle oil product with a recommended
mixing ratio of 100:1. If insufficient lubrication
is the cause of engine damage, it voids the
manufacturer’s engine warranty for that
occurrence.
WARNING:
Lack of lubrication voids engine
warranty.
