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.

CAUTION: If saw chain is TOO LOOSE or TOO
TIGHT, the sprocket, bar, chain, and crankshaft
bearings will wear more rapidly. Study Fig. 6 for
information concerning correct cold tension (A),
correct warm tension (B), and as a guide for
when saw chain needs adjustment (C).

• 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 professional Service Center for repair.

FUEL AND LUBRICATION
• FUEL
Use regular grade unleaded gasoline mixed with 40:1
custom 2-cycle engine oil for best results.
WARNING: Never use straight gasoline in your
unit. This will cause permanent engine damage
and void the manufacturer's warranty for that
product. Never use a fuel mixture that has been
stored for over 90 days.
WARNING: If 2-cycle 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 manu-
facturer's engine warranty for that occurrence.
• MIXING FUEL
Mix fuel with 2 cycle oil in an approved container.
Shake container to ensure thorough mix.
WARNING:

Gasoline and Oil Mix 40:1
• RECOMMENDED FUELS
Some conventional gasolines are being blended with
oxygenates such as alcohol or an ether compound to
meet clean air standards. Your engine is designed to
operate satisfactorily on any gasoline intended for auto-
motive use including oxygenated gasolines. It is recom-
mended to use unleaded petrol as fuel.
• CHAIN AND BAR LUBRICATION
Always refill the chain oil tank each time the fuel tank is
refilled. We recommend using 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.
