clockwise.
B. When the saw chain has proper tension, hold
nose of bar in the uppermost position and
tighten the 2 bar retaining nuts securely.
CAUTION: A new saw chain stretches,
requiring adjustment after as few as 5 cuts. This
is normal with a new chain, and the interval be-
tween future adjustments will lengthen quickly.
CAUTION: If the saw chain is too loose
or too tight, the sprocket, bar, chain, and crank-
shaft 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, op-
erator'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 in-
tended measure of protection if the saw is op-
erated carelessly. Always test the chain brake
before using your saw and periodically while on
the job.
To test the chain brake:
1. The chain brake is disengaged (chain can
move) when the brake lever is pulled back and
locked (Fig. 7A).
2. The chain brake is engaged (chain is stopped)
when the brake lever is in forward position.
You should not be able to move the chain
(Fig. 7B).
NOTE: The brake lever should snap into both po-
sitions. If strong resistance is felt, or lever does
not move into either position, do not use your
saw. Take it immediately to SPARKY professional
service centre for repair.

VI - Fuel and lubrication
FUEL
Use regular grade unleaded gasoline mixed with
SPARKY 40:1 custom 2-cycle engine oil for best
results. Use mixing 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 warranty
for that product. Never use a fuel mixture that
has been stored for over 90 days.
WARNING: If 2-cycle lubricant other
than SPARKY Custom Lubricant is to be used,
it must be 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 recommend-
ed mixing ratio of 100:1. If insufficient lubrica-
tion is the cause of engine damage, it voids the
manufacturer's engine warranty for that occur-
rence.

MIXING FUEL

Mix fuel with SPARKY brand 2 cycle oil in an ap-
proved container. Refer to the Fuel mixing table
for correct ratio of fuel to oil. Shake container to
ensure thorough mix.
WARNING: Lack of lubrication voids
engine warranty.
