2. Fan reverse rotation means that the air from the fan blows
to the outside of the machine. This can be used when
cleaning to remove insects or dirt stuck to the net.
Check first that there is no flammable or burning material in
the surrounding area that will be sucked in, then operate
the switch to rotate the fan in reverse.
3. Set lock lever (1) securely to LOCK position (L).
4. Use UP switch (9) or DOWN switch (10) to select “01: Fan
reverse rotation“, then press input confirmation switch (11)
to accept the input. The screen changes to the screen on
the right (green display). To switch the fan to reverse rota-
tion, press input confirmation switch (11).
(Press Back switch (8) to return to the previous screen.)
5. When the fan rotation is being changed, the screen
changes to the waiting screen. The engine is automatically
set to low idling, and after approx. 15 seconds, the fan
rotates in reverse. After another approx. 4 seconds, the
engine speed returns to normal.
NOTICE
q
The fan rotation speed is proportional to the engine speed. When the engine is running at low idling,
the fan also rotates at minimum speed. If it is desired to raise the fan rotating speed, use the fuel con-
trol dial to raise the engine speed.
q
When rotating the fan in reverse with the engine stopped, change to this screen, then turn the starting
switch to the START position. This screen does not change until the engine starts, so if it is desired to
cancel, turn the starting switch to the OFF position.
6. When the fan rotates in reverse, the screen switches auto-
matically to the screen shown on the right (yellow display).
While the fan is rotating in reverse, the screen maintains
this display.
