2.2 General safety instructions

CAUTION Risk of injuries and/or damage
Please read and follow the instructions in this manual. Otherwise you may get injured or your scooter may get damaged.
Keep the following general warnings in mind during use:

• Do not use your scooter if you under influence of alcohol, medicines or other substances that may influence your driving abilities.
• Be aware that some parts of your scooter may get very hot or cold due to ambient temperature, solar radiation, heating devices or due to the motor drive during the ride. Be careful when touching. Wear protective clothing if the  weather is cold. After a ride, wait till the scooter/motor has cooled down.
• Before switching the scooter on, be aware of the environment/situation in which you are located. Adjust your speed to this before driving off. We advise you to use the slowest speed setting to drive indoors. For outdoor driving you  can adjust the speed to a suitable speed at which you feel comfortable and safe.
• ALWAYS keep in mind that your scooter may stop suddenly due to a discharged battery or a protection that prevents your scooter from further damage. Also check the causes mentioned in chapter 5.
• Your scooter has been tested for electromagnetic compatibility and complies with the standard, see chapter 6. Nevertheless, sources of electromagnetic field may influence the driving performance of your scooter like the fields of  mobile phones, power generators or high-power energy sources. On the other hand, the electronics of your scooter can affect other electronic appliances too, like alarm systems of shops and automatic doors. We advise therefore to  check your scooter regularly for damage and wear, since these may enlarge the interference, see also chapter 4.
• Only drive on flat surfaces where all wheels touch the ground and where there is sufficient contact to operate the scooter safely.

Troubleshooting

Even if you use your scooter properly a technical problem may occur despite this.
In this case, contact your local specialist dealer.
WARNING Risk of injuries and damage to the scooter

• NEVER repair your scooter yourself attempting to solve the problem.
• For failures at the operating console you need to contact the specialist dealer. He decides if the console needs to be reprogrammed.

The following symptoms may indicate a serious problem. Therefore contact your specialist dealer always if you spot any of following deviations:

• Strange sound;
• Frayed/damaged wiring harnesses;
• Cracked or broken connectors;
• Uneven tread wear at one of the tyres;
• Jerky movements;
• Scooter deflects to one side;
•  Damaged or broken wheel assemblies;
• Scooter does not switch on;
• Scooter is powered, but does not move to the front or back.

In case of a possible problem, a system code is displayed by the blinking LED of the possible problem indicator, see §3.6.1 (16). The following table summarizes the possible system codes (number of blinks). Some problems can be solved  by yourself. For all problems marked in grey, consult your specialist dealer.
Table 1: Troubleshooting

The scooter switches OFF automatically if battery voltage drops below 21.0 V.
Recharge the battery. For more information see § 3.6.
2| Fault by low battery voltage| Battery voltage is low.
• Recharge the battery.
• Check battery, associated connection and wiring.
3| Fault by high battery
voltage| Battery voltage is high.
This may occur if battery is overcharged, for example while driving down a long slope. In such cases, reduce your speed to minimize charging of battery.
4| Current limit has been reached
Or
Temporary stop due thigh controller temperature| Maximum current rating of motor has been exceeded for too long.
• because the scooter has stalled. Switch the scooter off. Wait a few minutes and switch it back on.
• caused by a motor fault. Check motor, its associated connections and wiring. Scooter switches off automatically when temperature of controller or motor gets too high. This can be  caused by:
• driving up a long, steep slope;
• an ambient temperature which is too high;
• leaving the scooter in the sun for too long.
By switching the scooter off, all components are able to cool down. When the temperature is back to normal,  the scooter can be started again. But we advise to leave it OFF for 5 more minutes to let it cool down completely.
5| Brake fault| Either a brake release switch is active;
Or the brake system is faulty.
• Check brake and associated connections and wiring.
• Make sure that any associated switch is in its correct position.
Either a stop function is active;
Or charger inhibit;
Or OONAPU (*) condition has occurred.
6| Drive inhibit| • Release the stop conditions.
• Disconnect the battery charger.
• Make sure that the operating levers are in neutral position when the scooter is switched on.
• Possibly the operating-levers mechanism requires re- calibration.
7| Fault at speed control| Operating levers, speed control, SRW or their wiring may be faulty.
• Check the operating-lever mechanism and speed control and
associated connections and wiring.
8| Motor voltage fault| Motor and its wiring may be faulty.
• Check motor and associated connections and wiring
9| Other error| Controller may have an internal fault.
• Check all connections and wirings.

(*) OONAPU fault means “Out Of Neutral At Power Up”. This fault appears for example if the operating lever at the left or right side does not return to its neutral position causing the scooter to move the moment the ON/OFF switched is  being operated.
