PTO output speed with respect to engine speed is 47% is faster in gears R2, F3, 4, 7, 8, 11, 12, 1
and 16. DO NOT operate PTO in gears other than R1, N, 1 or 2 over 1700 RPM. To do so can
cause overheating and pump cavitation.
Make sure the dump bed is fully lowered so that its entire length rests on the chassis frame. If it needs to be
lowered, start the truck engine, engage PTO, and perform the following steps:
Clear all personnel from around the dump body.
Squeeze the hydraulic control lever head together (see fig. 2-5).
Move the shift lever toward the DOWN position.
After the dump body is fully lowered, release the lever head and place the
Figure 2-5. Hydraulic Control Lever.
If the truck is to be loaded with a hopper, make sure the truck is positioned so the hopper is directly over the
approximate center of the dump bed. When pulling under the hopper, check your truck clearance. If the truck
is to be loaded using a front-end loader, position the truck on firm level ground at a location that is convenient
for the loading operation. Position the truck for side loading.
