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 3.3.

3.2 STARTING & STOPPING – ENGINE, BLADES, PARKING BRAKE
This machine is equipped with dual hydraulic pumps and wheel drive motors. Each pump is controlled by a single motion control lever or joystick. This single control lever (joystick) controls the direction of motion, Forward and Reverse, and the speed of motion. Move the joystick forward to propel the machine forward. Move the control rearward to propel the machine in reverse. The speed of motion is continuously variable from neutral (zero) to maximum. Moving the joystick farther from the neutral position will cause the speed of motion to increase. To turn, move the joystick towards the side you want to turn to. DO NOT make sudden changes in speed or direction. Always slow machine motion before turning. To stop the motion of the machine, bring the joystick back 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, the motion control lever is in the neutral position with the parking brake engaged.
1.Complete
2.Sit in operator’s seat.
3.Push blade switch in to “OFF”, blades disengaged position and engage parking brake. See Figures 3.2 and 3.7.
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.
