Operation Product Overview Operation Note: Determine the left and right sides of the machine from the normal operating position. Controls Motion Control Levers The motion control levers located on each side of the console control the forward and reverse motion of the machine. Moving the levers forward or backward turns the wheel on the same side forward or reverse respectively. Wheel speed is proportional to the amount the lever is moved.
Operation Choke Control Pull the lever up and rearward to engage the brake. Located on right console (black lever) (see Figure 6). Push the lever forward and down to disengage the brake. The choke is used to aid in starting a cold engine. Moving the choke lever forward will put the choke in the “ON” position and moving the choke lever to the rear, to the detent, will put the choke in the “OFF” position. Do Not run a warm engine with choke in the “ON” position.
Operation Drive Wheel Release Valves WARNING Hands may become entangled in the rotating drive components below the engine deck, which could result in serious injury or death. Stop engine, remove key, allow all the moving parts to stop before accessing the drive wheel release valves. Figure 8 WARNING 1. LCD Indicators 2.
