OPERATION

CONTROLS (fig.6)

IMPORTANT: Ensure engine has correct oil level prior to each use.

• FUEL VALVE CONTROL (fig.6) The fuel valve opens and closes the fuel line between the fuel tank and the carburettor. The fuel valve lever must be in the ON position for the engine to run. When the engine is not in use, leave the fuel valve lever in the
  OFF position to prevent carburettor flooding and to reduce the possibility of fuel leakage.

• THROTTLE CONTROL LEVER (fig.6)
  The throttle lever controls engine speed. Moving the throttle lever makes the engine run faster or slower.

• ENGINE ON/OFF SWITCH (fig.6)
  The engine switch enables and disables the ignition system. The engine switch must be in the ON position for the engine to run. Turning the engine switch to the OFF position stops the engine.

• CHOKE LEVER (fig.6)
  The choke lever opens and closes the choke valve in the carburettor. The closed position enriches the fuel mixture for starting a cold engine.
  The open position provides the correct fuel mixture for operation after starting, and for restarting a warm engine.

• RECOIL STARTER GRIP (fig.6)
  Pulling the starter grip operates the recoil starter to crank the engine.

• FEED HOPPER (fig.5)
  The opening into which all materials to be chipped should be fed.

• DISCHARGE PORT (fig.4)
  Chipped materials are discharged through this opening. Deflector should be attached to the chute.

• DEFLECTOR LEVER (fig.4)
  Loosen it in the anti-clockwise direction to adjust discharge angle. Tighten it in the clockwise direction.

• EMERGENCY STOP (fig.7)
  Rotate the Emergency Stop button to engage this feature. The button will rise up.
  If an emergency stop is required whilst running, depress the switch. NOTE: the chipper will run on for a few seconds before stopping.
