SECTION 6—WHEELCHAIR OPERATION

Power Tiger™

32

Part No 1134839

Using the Joystick to Drive the Wheelchair

NOTE: For this procedure, refer to FIGURE 6.2.

The joystick is located on the joystick housing and provides smooth control of speed and 

direction. It is equipped with 360 degrees of mobility for ease of operation. The joystick is 

spring-loaded, and automatically returns to the upright (neutral) position when released. 

Pushing the joystick in a given direction causes the wheelchair to move in that direction. 
The joystick has proportional drive control, meaning that the further it is pushed from the 

upright (neutral) position, the faster the wheelchair moves. The maximum speed, 

however, is limited by the setting of the speed-control knob.
To slow the wheelchair to a stop, simply release the joystick. The wheelchair has 

automatic speed and direction compensation to minimize corrections.
When first learning to drive, select a slow speed and try to drive the wheelchair as slowly 

as possible by pushing the joystick slightly forward. This exercise will help you learn to 

utilize the full potential of the proportional control and allow you to start and stop 

smoothly.
To drive the wheelchair, perform the following:
1. Adjust speed control knob to the appropriate setting.
2. Turn the power On. Refer to Turning the Power On/Off on page 31.
3. Maneuver the joystick in the following manner:
