Operating Instructions - Section 30 03/13 OM3040 Page 30-12 Raising the Dump Body When dumping very large rocks or sticky mate- rial, the material may exit the body too fast. This may cause a violent jolt to the dump body and cause possible injury to the operator. Damage to the hoist cylinders, frame, and the dump body hinge pins may also result. If it is necessary to dump this kind of material, refer to the caution in the following procedure. 4. Move hoist control lever (1, Figure 30-4) to POWER UP position (4) and release the lever. FIGURE 30-3. HOIST CONTROL Releasing the hoist lever anywhere in the lever stroke when raising will place the dump body in HOLD at that position. 1.
Hoist Control Lever 2. FLOAT/HOLD Position 3. POWER DOWN Position 4. POWER UP Position 5. Center Console 5. Raise engine rpm to accelerate the hoist speed. Refer to the following caution note. When the body is near the maximum angle, reduce engine rpm in order to reduce the shock load to the hydraulic system and hoist cylinders. If dumping very large rocks or sticky material as described in the warning above, slowly acceler- ate engine rpm and raise the dump body. When the material starts to move, release the hoist lever to the HOLD position. If the material does not continue out of the dump body, repeat this procedure until the material has been dumped. 6.
When the dump body rises to the desired posi- tion, release the hoist control lever. The lever will return to the HOLD position. If necessary to raise the body further, move the dump lever to POWER UP. The dump body will rise until the hoist cylinders are fully extended.
