4.
Before replacing the fuel cap, clean and inspect the gasket.
5.
Immediately replace the fuel cap and tighten it by hand. Clean up any fuel spills.
CHECK AND ADJUST IDLE SPEED
Start the engine and leave it idle for about two or three minutes, or until it warms up.
NOTE: The screws of the mix are identified by the symbols L (low speed), H (high speed) and T
(accelerator), symbols that can be seen on the side of the chainsaw.
Do not touch the H and L screws.
1.
If the cutterbar rotates quickly while the engine is idling, reduce idle speed by turning the throttle counter
counterclockwise if necessary.
2.
If the engine stalls, increase the idle speed by turning the throttle screw clockwise.
CARBURETOR ADJUSTMENT
ATTENTION: The cutterbar can rotate when the engine is at idle speed.
NOTE
• The engine will return to idle speed after the throttle trigger is released.
• You may require a moderate level of mechanical knowledge for the maintenance of your
machine, if in doubt, please contact the Official Technical Service.
• As a rule, the engine idle speed should be reduced to a minimum so that the cutterbar does not
rotate quickly and the engine is only "running".
TURN THE IDLE AND MIXTURE SCREWS TO THE FACTORY SETTINGS
1.
Turn the idle speed screw clockwise until it starts to tighten (do not tighten).
2.
Turn the idle speed screw counterclockwise 5 turns.
3.
Turn the mixing screw clockwise until it starts to tighten (do not tighten).
4.
Turn the mixing screw counterclockwise. L 1,5 turns and H 1,25 turns.
NOTE: For high altitudes it is recommended to use low (3 times) and high (1.5 times)
5.
Now start the engine.
6.
Make sure the choke is down and the engine is warm.
7.
Pull the throttle trigger fully (full throttle).
8.
With the engine running at full speed, turn the mixing screw clockwise until the engine is running at full
speed.
ATTENTION: Prevent engine damage once the engine is running at full speed, turn the mix screw
counter clockwise 1/4 turn.
9.
For a good idle speed adjustment, place a cutting head and adjust the idle screw to minimize idle tool
movement while keeping the engine running smoothly.
