COMPOSITE BEARING INFORMATION FIG. A FIG. B Pin Seal Bearing Housing Pin Seal Bearing FIGURE A. Your GP/GL-Series loader is equipped FIGURE B. Even though the composite bearings on with composite, greaseless bearings at all (12) pivot points. These high-quality bearings should not be confused with plastic bushings, sintered bushings, or metal-backed bearings. Composite bearings are made from an ultra-strong fiberglass composite that has twice the compressive yield strength of plain carbon steel.

STEP 3 Gently lower the loader until the stand legs touch the ground.
QUICK-ATTACH INSTRUCTIONS UNCOUPLING 1. Raise sliding latches as shown in Figure 1. 2. Rotate QT pins out of the lower notches, raise, and then rotate them into the upper notches of the sliding latches as shown in Figure 2. 3. Slide the sliding latches down as shown in Figure 3. This secures the QT pins in the “up” position so they do not interfere when hooking up to the next attachment. COUPLING 1. Approach and hook onto the attachment with QT pins secured in the “up” position as shown in Figure 3. 2.
