Stowing the Jib

Warning

Do not lower the boom to an angle below 0° The jib could becomedisengaged and drop off. Always make sure that either the stowing pin or pivot pin is inposition before starting any crane operation. Without these pins inposition, the jib will drop off when an operation is started.

1. Select the jib set status on the load moment indicator.

Take the necessary precautions to ensure that nobody enters thework area over which the jib will swing. Anyone standing in this vicinity could beinjured. Also check the adjacent area for any structure or otherobstruction that may present a problem when operating the jib.

The load moment indicator's control functions and the automatic stop function aredeactivated when the jib set status is selected on the load moment indicator. Stow the jibcarefully with no load on the crane.

When working at an elevated position, use a platform or scissor lift to preventfalling and ensure safety.

Use the attached bolts and cotter pins to secure the lock pin, ropeguide pins, and stowing pin in position.

2. Place the auxiliary hook block in its stowing position.

3. Extend the boom until the yellow mark on the side of the 2nd boom section comes out of the base boom section.

4. Lower the boom to a 0° angle. Connect the anti two block device leads to the connector on the boom.

[NOTICE]

◆ Take care to the rope socket position when attaching it to the bracket. (See the enlarged portion of the figure.)

If positioned inversely, the rope socket hits the jib at the lower face when the auxiliary winch is operated, and the socket will be damaged.

5. Attach the rope socket to the jib bracket with the lock pin.

7. Use the jib handle to remove the connecting pin.

[NOTICE]

◆ If the boom is extended or lowered to raise the jib, the jib could be damaged. Use the auxiliary winch only.

6. Hoist up with the auxiliary winch to raise the jib to a position where the connecting pin can be easily removed.

8. Hoist down with the auxiliary winch until the wire rope becomes slack. Remove the rope socket from the jib bracket.

9. Remove the auxiliary winch wire rope from the anti two block device weight and the boom and jib sheaves. Replace the rope guide pins and set the pins back in their original position.

10. Place the weight for the anti two block device in its stowing position.

[NOTICE]

◆ Do not stand under the swinging jib.

13. Carefully fold the jib in toward the boom by pulling the guide rope.

11. Attach a guide rope to the jib head.

14. Slowly retract the boom completely. The jib head will be fitted on the stowing bracket.

◆ Make sure that the boom is fully retracted and the jib is fitted to the center support and the stowing bracket.

12. Use the jib handle to pull the set pin down. Lock the set pin in place by turning clockwise.

Warning

Always make sure that either the stowing pin or pivot pin is in place. Never perform any crane operation until the jib head stowingpin has been inserted as instructed in Step 16. After removing the pivot pin, proceed to Step 16 immediately.

[NOTICE]

◆ Operate the auxiliary winch carefully. If the wire rope is wound too far, the anchor will be broken. 19. Take in the auxiliary winch wire rope, leaving it slightly slack.

20. Select the boom lift status on the load moment indicator.

21. Raise the main hook block and make sure that the anti two block device is operating properly.

Flood Lamp Switch

When the flood lamp switch is turned ON, the flood lamps (one on the side of the boom, one on the front face of the swing table and one on the front face of the cab) will illuminate.

◆ Never turn ON the flood lamps when traveling.

Roof Wiper Switch

The roof wiper switch is used to turn the roof wiper ON and OFF.

Roof Washer Switch

[NOTICE]

◆ Do not use the wipers on dry glass; doing so will damage the glass. Wet glass by spraying the window with washer fluid before using the wipers.

◆ Never spray washer fluid continuously for more than 3 seconds and do not operate the washer switch when there is no window washer fluid. This practice may burn out the pump.

Washer fluid can be sprayed on the roof glass by pressing this switch.

Oil Cooler

When the hydraulic oil temperature goes above 122°F(50°C), the oil cooler begins to work. When the temperature gets higher than 185°F(85°C), the temperature warning lamp comes on. If the lamp lights, stop crane operation immediately. Wait until the lamp goes off and resume operation.
