A)  MAINTENANCE

A.1)   Monthly checks

A.1.a)      Apply a few drops of light oil on all mechanical joints and in the gears of the folding mechanism.

A.1.b)      All nuts and bolts are equipped with locking devices (lock nuts, self locking nuts, lock washers, thread lock liquid, etc), nevertheless check their tightening.


B)  TROUBLE SHOOTING

B.1)   General notices concerning electric failures
In the sections of this manual concerning the electric failures, the following definitions apply:

B.1.a)      A battery is in good order when:

B.1.a.1)     The tension at its terminals is not less then 25,6V

B.1.a.2)     Charging time of a completely empty battery, when it is a new one, is about 4 hours. However, more the battery is old, less is its capacity to take charge so that the charging time reduces.

B.1.a.3)     The terminals of the battery are not rusty or dirty: this would reveal bad quality of contact at these terminals.

B.1.b)      Integrity of a loom means that:

B.1.b.1)     Each of its wires is firmly connected to the corresponding male/female connector at its ends and each of these connectors is firmly connected to the corresponding female/male connector of the corresponding device.

B.1.b.1)     There are no visible damages, especially in tracts corresponding to the hinges between footboard and main frame (Pic B1.1 + Pic B1.2) and to the handlebar hinge (Pic B1.3).

B.1.b.2)     There is electric continuity in each of its wire. A multimeter allows to detect any steady discontinuity. But sometime a broken wire allows an unsteady electric continuity. To detect such case of failure, raise the front wheel of the scooter from the ground and while pressing the speed control lever move slightly in all directions each cable mainly in the tracts corresponding to the hinges between footboard and main frame (Pic B1.1 + Pic B1.2) and to the handlebar hinge (Pic B1.3): while moving each cable check if any irregularity of the motor. Any irregularity reveals that an internal wire is broken in that point.

B.2)   The traction motor runs irregularly

B.2.a)      Check integrity of the looms (See Sec. B.1.b)

B.2.b)      Carry out the following:

B.2.b.1)     Activate the main switch

B.2.b.2)     Raise the front wheel from the ground

B.2.b.3)     While pressing the speed control lever, move slightly in all directions the cable entering in the motor shaft (W – Pic B2.1) and observe if any irregularity in the motor running. If any irregularity, replace the motor
