Section 3 - OPERATING INSTRUCTIONSSection 3 - OPERATING INSTRUCTIONS
ROLL RELEASE: To roll the machine without the
engine running, pressure within the hydraulic pumps
must be released. There is a hydraulic pressure relief
valve on the upper side of each pump that is used to
release the pressure. Use a wrench to rotate both relief
valves counter clockwise two full turns to open. After
rolling machine, both relief valves must be rotated
clockwise to close valves and tighten securely before
operating machine. Machine will not move if relief
valves are open. See Figure 3.4.
