1. See “Operation 2.13.2 Outrigger Set Up Operation [1] Tasks to be Performed Upon Engine Stop” to rotate the outrigger rotary of all the outriggers outward, and pull out the inner boxes

2. See “Operation 2.2 Starting the Engine” to start the engine.

3. Check whether the outrigger lowers smoothly when one of the Outrigger individual setting switches (15) is turned to "OUT". Also, check whether the outrigger rises smoothly when that Outrigger individual setting switches (15) is turned to "IN". During the operation, check whethter any abnormal sound is made. Continue the same checking for rest of Outrigger individual setting switches accordingly.

4. Check whether the 4 outriggers lower smoothly when the Outrigger collective setting switches (16) is turned to "OUT".

Checking Crane Operations

Be sure to set the outriggers at the maximum extension state by referring to " Operation 2.13 Outrigger Set Up Operation" before checking the crane operations. Be sure to refer to the Operation sections between "2.14 Cautions before Crane Operation" and "2.23 Crane Stowing Operation", and strictly observe the methods described and cautions given when checking crane operations.

1. Refer to "Operation 2.15 Operations before Crane Operations" and slacken the wire rope which fixes the hook block (10) to release it from the hook holder (9), according to the procedure for it.

2. Verify that the boom rises smoothly when the boom derricking lever (4) is operated to "RAISE" side (pull toward you). Also, verify that the boom lowers smoothly when the boom derricking lever (4) is operated to "LOWER" side (push forward). When doing the above, check for any abnormal sound emitted by part of the boom or from the boom derricking cylinder. If there is any abnormality, repair.

3. Verify that the boom extends smoothly when the boom telescoping lever (2) is operated to "EXTEND" (push forward). Also, verify that the boom retracts smoothly when the boom telescoping lever (2) is operated to "RETRACT" (pull toward you).

When doing the above, check for any abnormal sound emitted by part of the boom or from the boom telescoping cylinder. If there is any abnormality, repair.

4. Verify that the hook is wound down smoothly when the winch lever (3) is operated to "DOWN" (push forward). Also, verify that the hook is wound up smoothly when the winch lever (3) is operated to "UP" side (pull toward you). When doing the above, check for any abnormal sound emitted by part of the boom or from the winch motor. If there is any abnormality, repair.

5. Verify that the crane smoothly slews counterclockwise when the slewing lever (1) is operated to "LEFT" side (push forward). Also, verify that the crane smoothly slews clockwise when the slewing lever (1) is operated to "RIGHT" side (pull toward you). When doing the above, check for any abnormal sound emitted nearby the post.
