(A).
4. Open the throttle
fully (B).
5. Push the throttle
latch backwards
(C).
Now all the controls
are in starting
position
and the chain saw is
ready to be started.
6 Put your right foot on the plate beneath
the rear handle
7. Grasp the front handle with your left hand and press the saw
against the ground.
8. Grasp the starter handle with your right hand and pull out the
starting
cord slowly until the starter pawl engage.
9. Give the starting
cord a short sharp tug.
NOTE!
Do not pu// the starting cord entire/y out or release
the starter
hand/e in pulled out position,
as this can cause damages
on the
chain saw.
10. Normally
the engine will start after 2-3 starting
attempts
Push
the choke control
as soon the engine starts. Open rapidly the
throttle
wide and the latch will disengage
To stop the engine push the ignition
switch to the right so that the
O is visible,
B. Warm engine
Use the same starting
procedure
as for cold engine
but without
pulling out the choke control
NOTE!
One of the most common
causes of starting
difficulties
is that too
many starting
attempts
have been made with a closed choke flap,
If this is the case, remove the spark plug and wipe it dry. Open the
choke flap fully.
Before you reassemble
the spark plug, we recommend
you to pull
the starter handle several times to "ventilate
the cylinder",
the
ignition
switch in O-position.
Assemble
the spark plug and make a new starting
attempt
with
open choke flap and full throttle.
CAUTION!
I
Guide bar, chain and clutch cover must be assembled
before
T
the engine
IS started,
otherwise
the clutch may come loose
and cause injuries.
Adjusting the carburetor
The carburetor
has three adjusting
screws:
L = Low speed needle
H = High speed needle
T = Throttle adjusting screw
A. Basic setting
Clean the alr filter.
Check the spark plug and its electrodes.
Check that the fuel filter is not clogged.
Screw the needles
H and L carefully
right in.
Then screw the needles
out to recommended
basic position:
H = 3/4 turn out, L = 1 turn out
Start the engine and warm It up. Adjust the idling speed by means
of the throttle
adjusting
screw to that speed at which the chain just
starts rotating.
B. Adjustment of L-needle
1.
Screw In the L-needle
slowly and the speed will increase.
Screw
in the needle a little further
and the speed will slow down again
as the fuel supply becomes
too "lean". Notice the position
of the
needle at the highest speed.
2. Open the L-needle
again and notice the highest
position.
Note
that the speed slows down at "richer"
supply.
3. Adjust the L-needle
to the highest speed position.
Then open it
equwalent
to 10 min on a clock-face
to obtain a somewhat
"richer"
supply to aid acceleration.
4. By means of the T-screw, adjust the idling speed to 2.300-2.500
r/mln, ensuring
that the chain does not rotate when engine
is
Idling
5. Give full throttle
a couple
of times to check that the engine
"responds".
If not, open the L-needle
by abt 3 min. Check again.

C. Adjustment
of H-needle
At correct
adjustment
of the H-needle
the engine should be four-
stroking.
Screw in the H-needle
slowly until there is no more four-
stroking.
Then screw the needle
out equivalent
to 10 min on a
clockface.
Check by means of a revolution
counter
that the high idle speed
does not exceed
11.500 r/rein.
