E. Starting and stopping
IMPORTANT
Never start or operate unless bar and chain are properly installed. Before starting always move the saw away from the fuelling area and place it on a firm, flat surface, the guide bar to the front.
STARTING A COLD ENGINE
1Check that the chain brake is in the disengaged position moving the lever (L) towards the front handle.
Move the stop switch upwards .
2Slide the choke lever (A) to the CLOSED position (OUT). Press the primer bulb (C) several times.
3Depress throttle trigger lock out (S). Depress throttle trig- ger (G) and then operate throttle advance (P) moving it backwards.
4Hold the saw firmly as shown in illustration and pull the starter rope until the engine fires once.
Beware of moving chain!
5Move choke lever (A) to the OPEN position (IN). Push the decompression valve (D) down if your models is fitted with
one.
Pull the starter rope until the engine starts.
Allow engine to warm up for ten seconds for better cutting performance.
Squeeze the throttle trigger (G) to release the throttle advance.
If engine fails to start, repeat these instructions.
6The engine is stopped by depressing the STOP switch to STOP position.
After lengthy use of the chain at full speed,we recommend to run the engine for a few seconds at idle speed before stopping it.
STARTING A WARM ENGINE
Check that the ignition switch is not in the “stop” position and do not use the throttle lock.
Hold the saw firmly, press valve (D) for decompression and pull the starter rope.
STARTING A WARM ENGINE AFTER
In the fuel tank as run completely dry, procede to start as with a cold engine.
F. Usage
IMPORTANT
Before using a chain saw read the Operator’s Manual and all safety precautions carefully.
FELLING TREES
–Make sure that there are no bystanders or animals in the work area.
–Study the direction of the fall of the tree and then plan your exit path away from the planned direction of fall.
–Don’t fell trees when there is a strong wind.
1Clear the tree base of interfering limbs and brush. Clean the work area from stones or other objects which could damage the chain. If the tree has large protruding roots, remove them before felling (see illustrations).
2A) Cut a felling notch (A) of 45°on the side you want the tree to fall to a depth of about one third of the trunk diameter (d). Then make a felling cut (B) about 5 cm higher than the felling notch on the opposite side of the tree. Make sure that the felling cut does not go right through the trunk. A hinge (C) must always be left to provide control over the direction of the fall.
B)Use wedges to control the moment and direction of the fall.
3When the tree starts to fall, walk away along your pre-
planned escape path.
CUTTING FALLEN TRUNKS
4A) Limbing thick branches. For limbing and bucking leave the lower limbs to support the log off the ground.
B)Supported at one end only. Begin with a bottom cut made by the upper side of the bar (A); the depth of the cut should be about one third of the log diameter. Finnish with a top cut (B) meeting the first one. With this technique splitting, cracking can be avoided
C)Supported at both ends. Begin with a top cut about one third of the log diameter. Then finish with a bottom cut (B) meeting the first one. this technique avoids the risk of pinching the bar in the log.
D)If the log is supported along its whole length it may be cut normally from above. Take care not to touch the ground with the chain.
•When working on a slope always stand on the uphill.
•When cutting prepared timber, use clamps or chocks to secure work.
•Use extreme caution when cutting small size brush and saplings which may catch the chain and pull you off balance.
G. Carburettor adjustment
We suggest carburetor adjustments are made by an author- ized servicing dealer.
The carburetor has three adjustment screws:
•L: The needle screw L governs the fuel flow at low speed and also the acceleration from low to full speed.
To set screw L: close screw L turning it clockwise without forcing.
ENGLISH - 4
Then open screw 1 1/4 full turn (counterclockwise) .
If acceleration is not smooth, open another 1/4 turn to increase fuel flow .
•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 .
