WARNING! For the Checking before Turning
ON the Transmitter, ensure that the engine
starter switch is in the OFF position, as well
as the Receiver main switch is OFF.
Otherwise, the engine may un-expectedly
starts and cause serious injury or death,
while checking the Transmitter.
Perform the following inspections white the
Transmitter power is OFF:
• Check the control levers, operation buttons,
LCD screen, Accelerator lever and Grip for oily
dirt or other soil.
Scrub away the dirt with a clean cloth or such,
when any.
• Check for foreign bodies such as particles of
small stone or sand, caught into small
openings in the vicinity of the control levers
and/or Accelerator lever.
Remove such particles completely, when any.
In the event where such particles are caught in
the small openings in the vicinity of the control
levers and/or acceleration lever, they may
disturb correct operations and cause

of the operation lever and control button, and
the Accelerator lever, as well as they smoothly
return to the each neutral position when the
finger is released.

and/or control button without delay, when any
of them show an incorrect action.

lever and/or control button brings troubles or
failures and cause a serious hazard.
