6. When the outrigger is completely retracted,
slowly release the Accelerator lever, then
release the outrigger operation lever to
return to its neutral position.
NOTICE: Repeat the same process to the other
three outriggers to retract all the four outriggers
completely and stow them to the proper position.
Operation in Crane Mode
WARNING!
• Ensure that all the outriggers are properly
installed.
Where outriggers are improperly installed, it
may result a serious hazard, such as a
Crane tipping.
• During crane operations, always refer to the
portable rated total load chart and avoid
over-loaded operations. Operations in over-
loaded conditions may damage or tip the
Crane, which results a serious hazard.
• Check the smooth and correct actions of
each operation lever of the Transmitter, and
that they smoothly return to the each
neutral position when the finger is released.
• Each operation lever of the Transmitter will
be blocked by its stopper when it is moved
full. When it is blocked, do not attempt to
push more, otherwise it may damage the
Transmitter and cause its fault; it may result
a serious accident.
• To toggle each operation lever to the
opposite side, or to use another lever,
always release the Accelerator lever, each
time. Also, to operate the Crane,
manipulate the operation lever first, then
pull the Acceleration lever, next. To stop the
operation of the Crane, release your finger
from the Accelerator lever, first, and next
discharge the operation lever.
• Always actuate the Accelerator lever with
caution to the acceleration rate.
It must be properly controlled to keep the
appropriate crane operation speed and
avoid any abrupt motion. Such abrupt
acceleration or deceleration especially while
a load is hung will make a large impact to
the Crane and may result a serious hazard
such as Crane tipping or damage.
• During a load is hung, do not attempt to
perform multiple operation at a time, the
hook raising and the boom derricking, for
instance. That may cause abrupt change of
the load condition and cause a serious
hazard such as the Crane tipping or
damage.
1. Ensure that the main switch of the Receiver
is in the OFF position.
2. Start the engine by the Starter switch of the
Crane.
3. Push the Power switch of the Transmitter to
power ON.
Confirm that the LCD screen shows the
mark as the figure and the "CRANE MODE"
is automatically provided.
