Then open screw 1 full turn (counterclockwise) .
If acceleration is not smooth, open another 1/8 turn to
increase fuel flow .
•
I: The I (IDLE) screw controls the throttle opening to gov-
ern idle speed (2800 min-1) adjust as necessary.
CAUTION: increased idle speed may cause chain move-
ment.
•
H: The needle screw H governs fuel flow at high speed
(throttle valve fully open).
To set hi speed screw H: close screw H turning it clock-
wise without forcing .
Then open screw 1 full turn (counterclockwise) .
If the engine speed is too high, open the screw about 1/8
turn (counterclockwise). Optimal adjustment is found
between 1 and 1 1/4 turns.
The carburetor is adjusted for normal operation during pro-
duction. When considerable changes of altitude require a
supplementary adjustment, contact an authorised service
station which offers the latest in tools, parts and technical
assistance.

Ensure engine is always switched off before any kind of
maintenance operation.

CHAIN: Check tension regularly. A new chain will require more
frequent adjustment. Loosen retention nuts. Tighten chain (see
assembly instructions). Tighten retention nuts and adjust.

AIR FILTER
To change fuel filter remove the tank cap and pull out the
filter with a piece of bent wire or long forceps. Replace the
filter as shown in the illustration and reposition it. It is rec-
ommended to replace the fuel filter at least once a year.
– A dust clogged air filter may cause carburetor problems.
This may prevent the engine from reaching its maximum
r.p.m. and cause high fuel consumption.
– Remove cover.
–
Wash filter in petrol (do not use fuel which is mixed with oil).
CHAIN BRAKE
– The filter can also be cleaned with compressed air.
– Replace filter if damaged or if it does not seal tightly in
the air box.

WARNING: Contact your service dealer if anything
appears wrong with your chain brake. Do not disassem-
ble or manipulate the mechanism of the chain brake.

SPARK PLUG
Remove and clean the spark plug every 30 hours. Check
the electrode gap (0,5/0,6 mm. - 0.025 inches).
– Clean the brake mechanism periodically (without disas-
sembling it) and control the wear of the band visually.
•
PERIODICALLY: It is important to clean the saw thor-
oughly particularly around cylinder fins to avoid over-
heating of the engine.
– Replace
spark plug about every 100 working hours or
whenever it is extremely encrusted.
encrusted electrodes can result from an incorrect
carburetor setting or from wrong fuel mixture (too much oil in

• LONG STORAGE: Empty fuel and run engine until dry.
I. Safety chain brake
Your chain saw is fitted with a safety chainbrake
designed to stop the chain in milliseconds in case of
kickback. Always hold the saw firmly in both hands.
Kickback may occur if the end of the bar (see illustrated
angle) touches any solid object.
Never attempt to start a cut with the end of the bar.
Kickback is a violent upward and rearward movement of the
bar and may cause you to lose control of the machine.
Therefore you should avoid starting a cut with this part of the
bar. Always keep a firm grip on the saw with both hands
because, in case of kickback, it is the contact of the left hand
with the brake lever which will help to engage the brake.
The chain brake does not provide a total protection if the machine
is used without taking the necessary precautions and mainte-
nances.
The chain brake is intended to engage automatically in case of
kickback.
The chain brake can also be engaged manually by pushing
the chain brake lever forwards.The manual use of the chain
brake is recommended only at idle.
Always test the chain brake before using your saw. Do this by
engaging the brake at idle (see below).
CHAIN BRAKE TESTING:
