Snapper HZT21481BV important safety instructions Operating Instructions, Starting Engine

Section 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.

2.Sit in operator's seat.

3.Push blade switch in to "OFF", blades disengaged position and engage parking brake. See Figure 3.2.
