B-150 and MX-1600
Vehicle controls

1. Start Switch: The start switch turns the vehicle electrical control system ON. This switch may or may not require a key to operate. Rotate the switch clockwise to turn the vehicle system ON and counterclockwise to turn the vehicle system OFF. The vehicle will not run when in the OFF position. 

The switch should be in the OFF position whenever the operator leaves the driver’s seat. This switch is designed to secure and disable the vehicle. The key can only be removed when the switch is in the OFF position.

2. Battery Status Indicator (Analog): The normal operating range is in the green zone. Park the vehicle for a few minutes for an accurate reading. The vehicle needs charging if it is in the yellow zone. During and immediately following charging, the needle will be in the red zone to the right. The needle will move through the green zone toward the yellow zone as the batteries discharge. 

Charge the batteries when the needle is in the yellow zone. If it is in the red zone to the left, the batteries are empty and the truck should be taken out of service and charged to avoid damaging the batteries.

3. Headlight Switch: Push the top of the headlight switch to turn the lights ON. Push the bottom of the switch to turn the lights OFF.

4. Hour Meter: The hour meter is optional. If equipped, the hour meter displays total time the vehicle has been in operation. Time is accumulated only while the vehicle is moving with the throttle pedal pressed.

5. Direction Control Switch: This switch determines the direction of travel. 

The switch has three positions: 

  • FORWARD: Push the top of the switch all the way in to travel forward. 
  • REVERSE: Push the bottom of the switch all the way in to travel in reverse. 
  • OFF: There is a center position between forward and reverse; this is the “direction” OFF position. The direction OFF position does NOT turn the vehicle control system OFF. Use the start switch to turn the vehicle control system OFF. 

Refer to the Start Switch entry in this section for details regarding turning the vehicle control system off.

6. and 7. Accessory Switches: Switches in these locations will control optional electrical devices installed on your vehicle such as strobe light, work lights, windshield wiper, etc.


Turn Signal Switch

B-150 and MX-1600
The turn signal switch is optional. If equipped, the turn signal switch lever is located on the left side of the steering column. 

Push the lever forward to activate the right turn signal, and pull the lever back to activate the left turn signal. 

The switch is not self canceling. You must return the switch to the center OFF position after the turn is completed.

Hazard Light Switch

Hazard light switch
The hazard light switch is found on the turn signal switch. The switch is a small tab or knob under the turn signal lever. 

To activate the hazard lights, pull the tab out. To turn the hazard lights off, push the turn signal lever forward or back.


Steering wheel
The steering wheel and steering system are like an automobile. To turn right, turn the steering wheel clockwise. To turn left, turn the steering wheel counterclockwise.

Foot Brake Pedal

brake pedal
The foot brake pedal is located to the left of the throttle pedal. This pedal is designed for operation with the driver’s right foot. It works like the brake in an automobile. Applying pressure to the brake pedal slows the vehicle according to the amount of pressure applied. Relieving pressure from the pedal releases the braking action.

Throttle Pedal

The throttle pedal is located to the right of the brake pedal. It controls the speed of the vehicle and operates like the throttle pedal in an automobile. 

Press the pedal to increase speed, and release the pedal to decrease speed.

Parking Brake

The parking brake is actuated with a hand lever. 

To set the parking brake, push down on the brake pedal and pull the lever back firmly. To release the parking brake, press the foot brake pedal, push the button on the end of the handle, then push the handle forward until it stops.

Horn Switch

The horn switch is located on the floorboard to the left of the steering column. Press the switch with your left foot to sound the horn, and release it to turn it off.


Operator Presence: A switch located under the driver’s seat disables the power to the vehicle when the driver leaves the seat. The driver must be seated for the vehicle to operate. Whenever the driver leaves the vehicle, the driver should turn the key switch OFF and place the direction control switch in the center OFF position. 

Warning: Do not dismount the operator’s seat while the vehicle is in motion. Getting off the seat will activate the Operator Presence circuit, rapidly slowing the vehicle and applying the park brake. The abrupt slowing of the vehicle may result in severe bodily injury.

Charger: The charger interlock is designed to disable the vehicle from being driven while the AC charging cord is plugged into a functioning power source. This interlock is located inside the charger cabinet.
