6. Troubleshooting
When climbing a hill, the front wheel slips.
The front wheel is too far forward of your center of gravity. Adjust the Firefly so that the front wheel is as
close as possible to the wheelchair without interfering with the wheelchair's footrests or your body.
While climbing, lean forward to place more weight on the front wheel.
The Firefly
TM
2.5 won’t turn on.
Check that all the connectors are connected. Make sure that the battery is fully charged by charging it for
3 to 5 hours, until the light on the charger turns from red to green. Press the button on the top of the
battery once to turn it back on, then press and hold, for two seconds, the right-hand button of the two
buttons on the bottom of the display.
The Firefly
TM
2.5 turns on but won't move forward or reverse.
If neither the forward nor reverse throttle work, the electronic brake may be engaged. This feature cuts
off all power to the motor when either brake lever is pulled. A circle symbol in the lower-left corner of
the display appears in bright yellow when the electronic brake is on. Check that nothing has broken or
moved out of place along either of the brake lines. Check that the brakes are not extremely tight and the
cables are still attached at the brakes, that the brake cable housing is in place at both the brake end and
the brake lever end, and that the brake levers are undamaged.
