Unfolding the Wheelchair

Attaching the Joystick Controller

The 360° joystick controller can be attached to either the left or right armrest for user convenience.

1. Locate the mounting bracket on the desired armrest.
2. Slide the joystick controller onto the bracket until it clicks into place.
3. Secure the controller using the provided screw or locking mechanism.
4. Connect the controller cable to the corresponding port on the wheelchair frame.

Connecting Power Cables

Ensure all power cables are securely connected before operating the wheelchair. Incorrect connections can lead to improper function or charging issues.

1. Locate the main power cable connectors near the battery compartment.
2. Connect the red power cord securely. Failure to do so may result in the charging indicator lighting up while charging, but not actually charging.
3. Verify that all motor cables are correctly plugged in. If the wheelchair operates in the opposite direction, check and correct the left and right motor wire connections.

Operating Instructions

Powering On and Off

• To power on: Press and hold the power button on the joystick controller until the indicator lights illuminate.
• To power off: Press and hold the power button again until the indicator lights turn off.

Driving the Wheelchair

The 360° flexible joystick provides precise control over movement.

• Forward/Backward: Gently push the joystick forward or pull it backward.
• Turning: Push the joystick left or right to steer.
• Stopping: Release the joystick to its neutral position. The EABS parking system will automatically engage, stopping the wheelchair safely.

Speed Adjustment and Horn

• Speed Adjustment: Use the '+' and '-' buttons on the joystick controller to increase or decrease the speed. The LED display will show the current speed setting.
• Horn: Press the horn button on the joystick controller to activate the horn for safety.

Manual Mode Operation

To push the wheelchair manually without power, you need to disengage the motors.

1. Ensure the handbrake is in the down position.
2. Pull out the clutches on both sides of the wheelchair (located near the rear wheels). This disengages the motors, allowing the wheels to move freely.
3. To re-engage electric power, push the clutches back in.
