*Note: Charger may become warm to the touch during charging. This is typical. It is
recommended that you keep it out of direct contact with combustible materials.

motor and tab washer (see the axle hardware diagram on the next page). Ensure that the tab
washers still lock into place on the axle.

forks by 0.5mm.
