Wrap load arms are adjusted at the factory for proper alignment. However, adjustment in the field may be necessary under the following conditions:

• If any interference between wrap load arms and hoist channel is noticed during normal wrap load cycle.
• When handler is fully raised with wrap roll in load arms and wrap roll core is not centered , front to rear, in the hoist channel.
• After replacing a lost or damaged wrap load arm.

Adjust wrap load arm position as follows:

1. Start machine and enter load wrap mode. (See LOADING MODULE BUILDER WRAP in this section.)

2. Raise scissor lift (hoist) all the way up using tether control.

3. Lower handler.

4. Remove wrap load arms from storage position and install in wrap load position.

5. Load empty or partial roll of wrap in load arms.

6. Raise handler and observe clearance between wrap load arm (A) and hoist channel (B) on each end of wrap roll.

7. Clearance (C) must be at least 3 mm (1/8 in.). To adjust clearance, loosen collar (D), move arm inward or outward as required, and tighten collar.

8. Raise handler to full up position.

9. Check position of wrap roll in hoist channel. When properly positioned, core of roll is centered in channel or just touching front leg of channel.

10. If necessary, adjust position of roll as follows:

    1. Loosen cap screws (E).

    2. Rotate retaining plate (F) to move roll forward or rearward as required.

    3. Tighten cap screws.

    4. Repeat for opposite end of roll.
