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.
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.
TO TEST CHAIN BRAKE:
1. The Chain brake is DISENGAGED (chain can move)
when BRAKE LEVER IS PULLED BACK AND
LOCKED (Fig. 7A).
2. The Chain brake is ENGAGED (chain is stopped)
when brake lever is in forward 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 AND LUBRICATION
FUEL
Use regular grade unleaded gasoline mixed with Talon
40:1 custom 2-cycle engine oil for best results. Use mix-
ing ratios in Section FUEL MIXING TABLE.
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 40:1 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.
MIXING FUEL
Mix fuel with Talon brand 2 cycle oil in an approved con-
tainer. Use mixing table for correct ratio of fuel to oil.
Shake container to ensure thorough mix.
WARNING: Lack of lubrication voids engine
warranty.

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. We recommend using Talon Chain, Bar and
Sprocket Oil, which contains additives to reduce friction
and wear and to assist in the prevention of pitch formation
on the bar and chain.
