Putting into operation
5. PUTTING INTO OPERATION
Before starting
Adjust the shoulder strap length and handle position so that you feel comfortably when
working. Recheck tightening of all screws, bolts and nuts.
Fuel filling
Gasoline – use only unleaded motor gasoline with octane number 95 (NATURAL 95).
Oil – use only high-quality two-cycle engine oil intended for high speed engines.
Mix with gasoline in 1:25 ratio and pour into the tank.
Gas lever and main switch
(STOP) (see Fig. 8)
The gas lever (1) with the electrical switch (2) are only partly mounted. Insert the gas cable
(47) into the carburetor drawbar groove and connect the electrical switch wires. The gas
lever is preassembled on the handle from the factory (3).
WARNING!
When adjusting the gas lever, be sure not to let the cutting tool rotate while
starting. The cutting tool would start turning at high speed abruptly and could be dangerous.
The gas cable must be adjusted so that the engine is running at idle thrust when releasing the
gas lever (the cutting tool is not rotating).
Starting
(see Fig. 9)
Press the gas lever to the ¼ of the gas lock and cage it.
Turn the main switch on.
Set the primer lever to the OFF (0) position.
Pull the starter quickly. If the engine started-up, move the primer lever into the ON (1) position
again. Repeat this procedure, until the engine starts-up and begins to run.
After having started-up, let the engine warm at idle speed 2,500-2,800 rpm for c. 2-3 min
before the load of the machine.
WARNING!
The cutting blade may begin rotating just when starting. When starting the
engine, the blade must not be touching anything.
Idle speed setup
(see Fig. 2)
If idle speed is too high or low, adjust the idle speed with the aid of the adjusting screw (3).
If the speed is too high, turn the adjusting screw counterclockwise.
If the speed is too low, turn the adjusting screw clockwise.
