8.2.1 OUTRIGGER SETTING

Avoid controlling outriggers collectively on ground conditions other than flat and leveled. Otherwise, 4 outriggers will not touch the ground consistently which makes the machine inclined and may result in tipping.

1. In accordance with “REMOTE CONTROL 6.2 Procedure in the Operation Mode”, enter into the “Outrigger collective setting mode”.

2. Turn one of the outrigger operation levers to “Extend (lower)” and pull the Accelerator lever slowly.

Notes

In Outrigger collective setting mode (ALL), operation of any control lever controls all the outriggers.

3 Just before outriggers touch the ground, slowly release the acceleration lever, then release the outrigger operation lever to return to its neutral position

4. Push Speed/Mode button in the mode condition of above 3. The operation mode is switched to “Outrigger individual setting mode”.

5 Turn one of the outrigger operation levers to “Extend (lower)” and pull the Accelerator lever slowly.

Notes

Repeat the same process to the other three outriggers and contact all the four outriggers to the ground.

6. Push Speed/Mode button in the mode condition of above 5 The operation mode is switched to “Outrigger collective setting mode”.

7. Move one of the outrigger operation levers to “Extend (lower)” and pull the Accelerator lever slowly.

Notes

In Outrigger collective setting mode (ALL), operation of any of control levers controls all the outriggers.

8. When the Crane is elevated “approximately 50mm”, slowly release the Accelerator lever, then release the outrigger operation lever to return to the neutral position.

9. Use the level gauge on the machine body and check the levelness of the machine.

When the machine is not level, push Speed/Mode button in the mode condition to switch to "Outrigger individual setting mode" and control each outrigger individually so that the machine is set level.

Caution

To change from "OUTRIGGER MODE" to “CRANE MODE”, turn OFF the power using the Power switch and turn it ON again. Then the mode is automatically set to “CRANE MODE”.

8.2.2 OUTRIGGER STOWING [1] OUTRIGGER COLLECTIVE SETTING

1. In accordance with “REMOTE CONTROL 6.2 Procedure in the Operation Mode”, enter into the “Outrigger collective setting mode”.

2. Turn one of the outrigger operation levers to “Retract (upper)” and pull the Accelerator lever slowly.

Notes

In Outrigger collective setting mode (ALL), operation of any of the control levers controls all the outriggers.

3. When the Crane touches the ground, slowly release the acceleration lever, then release the outrigger operation lever to return to its neutral position.

[2] OUTRIGGER INDIVIDUAL SETTING

1. Push Speed/Mode button in the mode condition of above 1. The operation mode is switched to “Outrigger individual setting mode”.

2. Move one of the outrigger operation levers to “Retract (upper)” and pull the Accelerator lever slowly.

3. If the outrigger operation stops, slowly release the acceleration lever, then release the outrigger operation lever to return to its neutral position.

Notes

• Repeat the same process to the other three outriggers and lower all the four outriggers equally and gradually, so that the Crane is grounded.

• After the Crane is grounded, lower all the four outriggers completely.

Caution

To change from "OUTRIGGER MODE" to “CRANE MODE”, turn OFF the power using the Power switch and turn it ON again. Then the mode is automatically set to “CRANE MODE”.

8.3 OPERATION IN CRANE MODE

• Ensure that all the outriggers are properly installed. Where outriggers are improperly installed, it may result a serious hazard, such as the 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 may result in a serious hazard.

• Check for smooth and correct actions of each operation lever of the Transmitter, and that they smoothly return to the 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 a fault; and may 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 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 release 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. Any 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.

• Whilst a load is hung, do not attempt to perform multiple operation. Such as, hook raising and the boom derricking, for instance. That may cause an 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 at the Starter switch of the Crane.

Caution

Prior to starting the engine, perform the 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 the figure on the right and the “CRANE MODE” is automatically provided.

5. In accordance with “REMOTE CONTROL 6.2 Procedure in the Operation Mode”, enter into the “CRANE MODE”.

8.3.1 SLEWING OPERATION

For the slewing operation, actuate the Accelerator lever carefully and always keep in low speed. Also, actuate the Accelerator lever slowly and delicately to avoide abrupt slewing Any abrupt acceleration or deceleration, especially while a load is hung will make a large impact to the Crane and may result in a serious hazard such as Crane tipping or damage.

[1] SLEW CLOCKWISE

Push the Slewing/No.1 outrigger operation lever to “Clockwise (lower)”, then pull the Accelerator lever slowly. The boom slews clockwise, looking down at the Crane from the sky.

[2] SLEW COUNTERCLOCKWISE

Push the Slewing/No.1 outrigger operation lever to “Counter clockwise (upper)”, then pull the Accelerator lever slowly. The boom slews counterclockwise, looking down at the Crane from the sky.

[3] STOP SLEWING

Release the Accelerator lever slowly, then release the Slewing/No.1 outrigger operation lever to return it to its neutral position. The boom stops slewing.

8.3.2 BOOM TELESCOPING

Push the Boom telescoping/No.2 outrigger operation lever to “Extend (upper)”, then pull the Accelerator lever slowly. The boom extends.

[2] BOOM “RETRACTING”

Push the Boom telescoping/No.2 outrigger operation lever to “Retract (lower)”, then pull the Accelerator lever slowly. The boom retracts.

[3] STOP TELESCOPING

Release the Accelerator lever slowly, then next release the Boom telescoping/No.2 outrigger operation lever to return it to the neutral position.

The boom stops telescoping

8.3.3 HOOK RAISING AND LOWERING

• In the event of “Over-hoist alarming” or “Automatic cut out” during the hook raising operation, immediately stop winding. Otherwise, it may cause damege to the Crane, or a broken wire-rope which will result in dropping of the hook or laod; and a serious accident may happen.

• Continuing hook lowering in the condition that the load has already reached the ground, will cause random winding of the wire-rope. This may damege the wire rope or shorten its life badly. Further, there is some risk that the wire-rope may tangle itself which prevents any more winching. During the hook lowering, always take good care not to cause such random winding.

• The hook is also raised or lowered by boom telescoping or derricking. The same attention must be paid to the hook raising and lowering as in the winching operation.

[1] HOOK RAISING

Push the Hook raising and lowering/No.2 outrigger operation lever to “Raise (upper)”, then pull the Accelerator lever slowly. The hook starts to rise.

[2] HOOK LOWERING

Push the Hook raising and lowering/No.2 outrigger operation lever to “Lower (lower)”, then pull the Accelerator lever slowly. The hook starts to lower.

[3] STOP RAISING OR LOWERING

Release the Accelerator lever slowly, then release Hook raising and lowering/No.2 outrigger operation lever to return it to the neutral position.

The hook stops raising or lowering

8.3.4 BOOM DERRICKING

[1] BOOM RAISING

Push the Boom derricking/No.4 outrigger operation lever to “Raise (upper)”, then pull the Accelerator lever slowly. The boom will rise.

[2] BOOM LOWERING

Push the Boom derricking/No.4 outrigger operation lever to “Lower (lower)”, then pull the Accelerator lever slowly. The boom will lower.

[3] STOP BOOM DERRICKING

Release the Accelerator lever slowly, then release the Boom derricking/No.4 outrigger operation lever to return it to the neutral position.

The boom stops derricking

8.3.5 SET-UP AND CANCEL MICRO SPEED

When it is required to operate the Crane in low speed, use the Micro speed mode, which limits the maximum speed of the Crane and facilitates the smoother control in the low speed range. This machine offers 2 modes for limiting the maximum speed of the Crane. One is the "MICRO SPEED MODE" and the other is the "USER MICRO SPEED MODE", which the user can select their own setting.

“MICRO SPEED MODE” is available by user selection.

Notes

“MICRO SPEED MODE” is valid only in the “CRANE MODE”.

[1] SETTING THE MICRO SPEED MODE

Push the Speed/Mode button.

Each push will forward the LCD screen indication as shown in the diagram, below:

When the indicated mode fits your requirement, carry on the Crane operation in that condition.

[2] CANCEL THE MICRO SPEED MODE

Push the Speed/Mode button several times, until LCD screen indication attains the “Normal”

Setting to the User micro speed mode requires actual crane operations with the engine running. Before starting the User micro speed mode setting, always ensure that nobody other than those involved with the operation are within the working area.

1. Push the Speed/Mode button several times so that the LCD screen indicates the “USER MICRO SPEED MODE”.

2. Push the Setting button for at least 2 seconds. Indication of “F” in the LCD screen is high-lighted and it enters into the “USER MICRO SPEED MODE” setting screen.

Notes

The “USER MICROSPEED MODE” setting is available while the “F” in the LCD screen is high-lighted.

3. Push the operation lever to be adjusted and pull the Accelerator lever slowly.

When the operation speed reaches the desired maximum speed, push the Setting button.

Notes

Please understand that in the "USER MICRO SPEED MODE", when you set two or more control levers at the same time and pull the Accelerator lever, the crane operation speed follows the operation which is set to the fastest operation

4. When the settings for all the required operation levers are complete push the Speed/Mode button. Now the setting is established and the Micro speed mode is available.

8.3.6 ENGINE STOP AND EMERGENCY STOP PROCEDURE

• For any abnormalities in crane operations, immediately push the Stop/EMO button to stop the engine. This includes such cases as, crane operation does not stop even though you release your fingers from any of the operation levers or Accelerator lever, or the Crane starts any operation even though no operation lever is manipulated

• In the event of an emergency stop of the engine, turn OFF the power of the Transmitter and check the cause of the emergency, after the engine stops, and repair the failure.

• The Stop/EMO button is also able to stop the engine in normal conditions.

Push the Stop/EMO button to stop the engine from the Transmitter or in case of emergency. The engine stops.

8.3.7 ENGINE START AND RESET PROCEDURE

[1] ENGINE START PROCEDURE CAUTION

• Follow the procedure below for use of the Start/Reset Button to start the engine:

1. Position the Starter switch of the Crane to ON.

2. Set the travelling stand of the Crane to CRANE position. If the Starter switch of the Crane is in OFF position or if the travelling stand of the Crane is in TRAVELLING position, you can not start the engine.

• Prior to starting the engine, perform the 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.

When it is required to start the engine from the Transmitter, push the Start/Reset button. The engine starts.

• When the Start/Reset button is used, firstly push the Power switch of the Transmitter to turn it ON.

• When the Start/Reset button is pushed, the abnormal signal detector circuit starts working. Wait for 3 to 4 seconds until it completes.

8.4 CHECKING AFTER CRANE OPERATION

• When the operation of the Crane is finished, always turn OFF the Transmitter and Receiver power.

• On no occasion except for Crane operations, must the power of the Transmitter be turned ON. That could cause an un-expected motion of the Crane and result in a serious hazard, such that the Crane hitting someone or an object, or the Crane could tip.

• When it is required to turn ON the Transmitter for the purpose of inspection or such, ensure first that the engne is not running, then shut down the Receiver by turning OFF its main switch.

1. Enter into the “CRANE MODE” of the Transmitter operation mode.

2. Use the operation levers and retract the boom to its shortest condition and lower it to the base position
