Drive Levers

Located on each side of the upper handle assembly ahead of and below the handle grips (see Figure 4 and Figure 5).

These levers individually control clutching action of the wheel drive belts and brakes. When the drive levers are all the way down, the brakes disengage and the wheel drive belts engage

Gradually squeezing the left or right hand drive lever disengages the wheel drive belts, causing the left hand or right hand wheel to slow down until they reach neutral or stop. This makes the machine turn to the left or right respectively. Squeezing further engages the park brakes. The sharpness of the turn varies by how much the lever is squeezed. For straight ahead motion, smoothly release both drive levers to engage both drive wheels simultaneously.

Neutral Lock/Park Brake Latches

•For Pistol Grip Handles: Located on handles ahead of the grips.

•For ECS Handles: Located on the upper handle assembly on the ends of the handle grips.

The latches allow the operator to lock the drive levers in a “neutral” position where neither the wheel drive belts nor the brakes engage or in a “park brake” position where the wheel drive belts are not engaged and the park brake is engaged (see Figure 4 and Figure 5).

Choke Control

Located on the front left corner of the fuel tank support.

Choke is used to aid in starting a cold engine. The choke control is pulled out to be in the “ON” position and pushed in to be in the “OFF” position. Do Not run a warm engine with choke in the “ON” position.

Throttle Control

Located on the on the control console right side.

The throttle is used to control engine speed. Moving the throttle control forward will increase engine speed and moving it to the rear will decrease engine speed. Moving the throttle forward into the detent is full position.

Transmission Shift Lever

Located under the control console and behind the fuel tank.

It shifts the 5-speed transmission into five forward gears, neutral and reverse. Shift transmission only when drive levers are in the neutral position. Shifting without drive levers in neutral may cause damage to the transmission.

Note: Reverse is “reverse assist” only, meaning when the transmission is in reverse, the operator has to pull the unit backward to “assist” with the movement of the unit.

“Off-Run” Switch

Located on the control console.

Turn the key to the “Run” position to allow the engine to be started. Turn the key to the “Off ” position to shut engine off.

Fuel Shut-Off Valve

Located in the fuel line midway between the tank and engine.
