8.2 OPERATION IN OUTRIGGER MODE • Check for smooth and correct actions of each operation lever of the Transmitter, and that they smoothly return to each neutral position when the finger is released. • Each operation lever of the Transmitter will be blocked by its stopper when it is moved fully. When it is blocked, do not attempt to push further, otherwise it may damage the Transmitter and cause faults and result in 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 outriggers, manipulate the operation lever first, then pull the Accelerator lever. To stop the actuation of outriggers, release your finger from the Accelerator lever first, then discharge the operation lever. • For the outrigger operations, always keep the engine speed in the low or middle range. Such operation in the high speed range makes the outriggers actuate too quickly, which may tip the Crane and result in a serious hazard. • For the outrigger operations, always configure the Crane to the stow position. In the condition that the boom is raised or any load is lifted, it may cause a serious accident, such as tipping of the Crane. • For the outrigger operations, always ensure that the position pin of each outrigger is securely inserted. In the event where the pins are missing, the Crane may be tipped over and cause a serious hazard. • For the installation of outriggers, always extend them first in the “Extension mode”, then switch the mode to “Ground setting mode”. Lift each outrigger equally and gradually, until the Crane is properly elevated. For the stowing of Outriggers, lower each outrigger equally and gradually, until the Crane is grounded in the “Ground setting mode”, then switch to the “Extension mode” to retract them. Unless this order is followed, it may cause the crane to tip and result in a serious accident. 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.

CAUTION Prior to starting the engine, perform following practices on the Crane. 1. Set the Acceleration Lever to the medium speed (about middle of its stroke). 2. Pull out the choke knob. 3. Return the choke knob to its initial position, when the engine starts.

3. Then turn ON the Main switch of the Receiver.

NOTES When the Main switch of the Receiver is turned ON, the abnormal signal detector circuit works for 3 to 4 seconds. During this time the Crane is not ready for operation.

4. Push the Power switch of the Transmitter to power ON. Confirm that the LCD screen shows the mark as in the figure on the right and the “CRANE MODE” is automatically provided.
