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 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 3.3.

3.2 STARTING & STOPPING – ENGINE, BLADES, PARKING BRAKE

This machine is equipped with dual hydrostatic wheel drive transmissions. Each hydro pump is controlled by a separate motion control lever. The left lever controls the left wheel drive hydro pump and the right lever controls the right wheel drive hydro pump. These levers control the direction of motion, Forward & Reverse, and the speed of motion. Move both levers forward to propel the machine forward. Move both levers rearward to propel the machine in reverse. The speed of motion is continuously variable from neutral (zero) to the maximum. Moving the levers farther from the neutral position will cause the speed of motion to increase. To turn, move the lever on the side to which you want to turn slightly rearward of the other lever. Move levers slowly and carefully. DO NOT make sudden changes in speed or direction. Always slow machine motion before turning. To stop the motion of the machine, bring both motion control levers to the neutral position. Engage parking brake.

3.2.1. STARTING ENGINE

When the ignition key is turned the engine will not start or turn over unless, the blade switch is pushed in to the “OFF” position and the motion control levers are in the neutral lock position. Always engage parking brake before starting engine.

1.Complete pre-start checklist.

2.Sit in operator’s seat.

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

4.Move choke control forward to choke position to start a cold engine. See Figure 3.5.

5.Move engine speed control to the Rabbit “FAST” position. See Figure 3.5.

6.Turn key to the start position until engine starts. See Figure 3.6.
