5. Attach the coupling cover (Fig. 5) and turn
the bar fastening wheel (B) clockwise to se-
cure it. The chain is not allowed to slip off the
guide bar when you do this. Tighten the bar
fastening wheel by hand and then follow the
instructions for adjusting the chain tension as
described in the section ADJUSTING THE
CHAIN TENSION.
5.3. Adjusting the chain tension
The correct tension of the saw chain is extremely
important and must be checked before starting
and during all sawing work. If you take time to
adjust the saw chain correctly, you will be able to
make better cuts and the life of the chain will be
prolonged. Caution: Wear high-strength gloves
at all times when handling or adjusting the saw
chain.
1. Hold the tip of the chain bar upwards and turn
the chain tensioning wheel (D) IN CLOCKWI-
SE DIRECTION in order to increase the chain
tension (Fig. 5). If you turn the chain tensio-
ning wheel IN COUNTER-CLOCKWISE DI-
RECTION, the chain tension will be reduced.
Check that the chain is seated around the
entire chain bar (Fig. 6).
2. After making the adjustment and with the tip
of the bar still upwards, tighten the bar faste-
ning wheel (B). The chain is correctly tension
when it is closely seated and can be pulled
right around by hand.
Note: If the chain is hard to turn around the chain
bar or blocked, it is too tightly tensioned. Make
the following small adjustments:
A. Undo the bar fastening wheel (B) by 1/2 re-
volution. Slacken the chain tension by slowly
turning the chain tensioning wheel (D) IN
COUNTER-CLOCKWISE DIRECTION. Pull
the chain back and forth on the bar. Do this
until the chain can be moved smoothly but
is still closely seated. Increase the tension
by turning the chain tensioning wheel IN
CLOCKWISE DIRECTION.
B. When the saw chain is correctly tensioned,
hold the tip of the bar upwards and tighten the
bar fastening wheel (B).
Note: A new saw chain stretches, requiring ad-
justment after as few as 5 cuts. This is normal
with a new chain, and the interval between future
adjustments will lengthen quickly.

Note: If the saw chain is TOO LOOSE or TOO
TAUT, the drive wheel, chain bar, chain and crank
shaft bearing will suff er premature wear. Fig. 6
shows the correct tension A (when cold) and ten-
sion B (when warm). Fig. C shows a chain that is
too loose.
5.4 Chain break 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 kick-
back, operator's hand strikes the lever. When the
brake is actuated, chain movement stops abruptly.
Danger: 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 (the chain is
locked) when the brake lever is pulled forward
and the mechanism (Fig. 7B/Item A) can be
seen. It should not be possible to move the
chain (Fig. 7B).
Danger: 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.
5.5 Fuel and lubrication
Fuel
Use regular grade unleaded gasoline mixed with
40:1 custom 2-cycle engine oil for best results.
Mixing fuel
Mix fuel with 2 cycle oil in an approved container.
Shake container to ensure thorough mix.
Note: 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.
