Petrol-Powered Chainsaw – SX62
13
NOTE
: Be sure to adjust the carburettor with the bar chain attached.
1. Stop the engine and screw in both H and L needles until they come to a complete stop. Never force the
screw in. then, set them back to the initial number of turns as shown below:
H Needle: 1 3/8
L Needle: 1 ¼
2. Start the engine and allow it to warm up a half-throttle.
3. Turn the L needle slowly in a clockwise direction to find a position where idling speed is at its maximum, then
set the needle back to a quarter (¼) turn in a counter clockwise direction.
4. Turn the idle adjusting screw (T) counter clockwise so that the saw chain does not turn. If the idling speed is
too slow, turn the screw clockwise.
5. Make a test cut and adjust the H needle for best cutting power, not for maximum speed.
Carburettor Anti-Freeze Mechanism
Operating the chain saw in temperatures of 0 – 5°C at times of high humidity may result in ice forming within the
carburettor, and this in turn may cause the output power of the engine to be reduced or for the engine to fail to
operate smoothly. This chainsaw has been designed accordingly with a ventilation hatch at the back of the air
cleaner cover to allow warm air to be supplied to the engine so as to prevent icing from forming.
Under normal circumstances, the chainsaw should be used in normal operating mode, i.e., in the mode in which
it is set at the time of shipment.
However, when the possibility exists that icing may occur, the unit should be set to operate in anti-freeze mode
before use (F15).
