OMCC58808: 533, 583, 633, 653, 663, 683, 753 Loaders and 746 Loader (005000- ), Block File: OUCC006_0001217_19

causym CAUTION: To prevent serious injury, implement must be attached and detached by the tractor driver himself.

1. Clean any debris off of auto-latch device, implement holder and implement attaching points.

2. Place auto-latch device in unlatched position.

a. Loaders without hydraulic implement unlatching:

Extend bucket cylinders to angle the implement holder forward.

Engage parking lock, apply handbrake, shut off engine, remove key.

Pull handle of auto-latch device, then turn it clockwise to lock it in its extended position as shown.

Open cover (A).

Before each connection, carefully clean the mating surface of base and top case as well as guiding pins.

Push on lock button (D) and simultaneously pull up lock cam lever (B).

Engage top case (E) on base (C), then pull down lock cam lever (B) until lock button (D) engages, so that top case (E) is connected to base (C).
