Montage

Assemble your SO4 2ND GEN / SO4 PRO / SO4 PRO 2ND GEN

Straighten the front bar as shown in the figure. Push the folding lever firmly as shown in the illustration to lock the front bar. Please check the tyre pressure. The tyre pressure should be 2,5bar.
Insert the exposed cable into the front bar. Then insert the handle bar into the front bar as well. Use the tool and screws to bolt the handlebar to the front bar.
After assembly, test whether the SO4 2ND GEN / SO4 PRO / SO4 PRO 2ND GEN can be switched on.

Folding / Storage of the SO4 2ND GEN / SO4 PRO / SO4 PRO 2ND GEN
Before folding the SO4 2ND GEN / SO4 PRO / SO4 PRO 2ND GEN, make sure that the scooter is switched off. Press the buckle as shown in the illustration and pull the lever down. Fold the front bar down to the rear mudguard and lock the hook on the buckle on the mudguard.

Instructions on adjusting the dics brake
If the brakes are too tight, use a 5mm Allen wrench to loosen the screw of the pressure plate by turning anticlockwise. Shorten the length of the brake wire to loosen the brakes, then tighten the screw again. If the brakes are too loose, loosen the screw and pull the brake wire to extend the wire, then tighten the screw again.

Inflating the tyres
In case that the tyres start lose pressure, you should inflate them to the recommended pressure.

Mobile phone holder

Your SO4 2ND GEN / SO4 PRO / SO4 PRO 2ND GEN comes with a mobile phone holder which can be easily attached or detached. Simply wrap the strap around the handlebar, pull it through the buckle and make sure it is firmly secured. You can pull around the mount to check if your mobile phone is firmly held in place. The stretchable silicon bands can hold all smartphones with a screen size from 4 to 6.2 inches.

WARNING!

Battery and charger

The range of the battery may differ from the specifications depending on the temperature, the condition of the track, the incline and the weight of the driver.

Charging the battery
Make sure that the charging connector and the charger are dry and that the SO4 2ND GEN / SO4 PRO / SO4 PRO 2ND GEN is switched off. Connect the charger cable to the scooter’s charging connector and plug it into an electrical outlet. The charging light on the charger should glow red. When the charging light changes from red to green, the battery is fully charged. Disconnect the charger from the power source and the scooter.
The e-scooter should only be charged with the original charger. Ensure that the voltage supply is correct. Do not use the charger if the charger or power cable are damaged. Please contact the service department. For optimum battery life, charge and store the e-scooter in a dry and clean environment, preferably room temperature. The charging time of the scooter is approximately 4 – 5 hours. There will be negative effects on the battery life if the charger remains permanently connected to the scooter and the power source.

Battery handling
Do not cover the scooter or the charger during charging. Lithium batteries have different freezing points depending on their charge level. If a battery cell freezes, it is irreparably destroyed and the entire battery must be replaced. As with conventional batteries, a lithium battery loses up to 40% of its capacity starting from approximately 0°C.

Correct handling of the battery
Never remove the battery from the scooter. Charge the battery for at least 1 hour every month (even when not in use). Never heat the battery or expose it to open fire. Never dispose of the battery cells together with general waste. Never bring battery contacts into contact with moisture. The ideal operating temperature of the battery is between 10°C and 30°C. Above as well as below this temperature, the power output deteriorates, resulting in a reduced range and power output.
The life and performance of a battery depends on its age, care and how often it has been used. Compared to other battery models, lithium ion batteries have very low self-discharge and a very low memory effect, but they need to be charged periodically. Even if you do not use your scooter, the battery must be charged for at least 1 hour every month, otherwise it will lose capacity. Regular charging will prevent the battery from total discharge. Please note that an excessively discharged battery is irreparably damaged and must be replaced for a fee, hence the battery should never be completely discharged during operation.

SO4 PRO 2nd Gen – Changeable battery

Connect the e-scooter to the corresponding app and press “UNLOCK”.

The cover of the battery compartment will then pop open slightly. Lift the cover upwards by more than 90 degrees with your hand.

|
---|---
Once the battery compartment is open, pull the battery upwards by the tab (1) and then pull the battery towards the rear wheel.|
Pull the battery upwards and release it from the case.|
When you want to close the battery compartment, fold the cover back in. The closing mechanism will automatically engage.|

Do not close the compartment if there is no battery in it. Otherwise, the compartment cannot be opened again.

If this still happens, you must lift the cover pad at the marked location so that you can loosen the two screws located underneath. Loosen the two marked screws to be able to open the cover again.

Maintenance

Do not try to charge the SO4 2ND GEN / SO4 PRO / SO4 PRO 2ND GEN when the battery is already full. This could diminish the battery’s capacity in the long run.

Before every ride, check all screws of the device, especially those of the handle and frontbar, the mudguard and the front and rear wheel. Tighten all screws firmly to ensure safety when using your SO4 2ND GEN / SO4 PRO / SO4 PRO 2ND GEN.

Before each journey, check that the wheels are undamaged.

Check regularly that the brakes are correctly adjusted. You can adjust the braking force by adjusting the brake cable. If in doubt, contact your dealer.

Thoroughly clean the SO4 2ND GEN / SO4 PRO / SO4 PRO 2ND GEN with a dry cloth after usage. The front and rear ball bearings must be lubricated from time to time. Ordinary bicycle oil can be used. Oil the area where the axle runs into the wheel to ensure better durability.

Turn signal operation

The control for the turn signals is located on the left side of the handlebar above the switch-on button. The turn signals are located at the end of the handlebars. They are intended to serve as an additional indication for changing direction and are particularly visible from the onset of dusk. Please always drive with foresight and in accordance with the applicable road traffic regulations. Bear in mind that these turn signals are a new product feature which is still unknown on the market. The indicator should be operated in good time before changing direction. To operate the left indicator, briefly press the button with the arrow to the left once or this to the right for right. To end the function, briefly press the respective button again. Please keep both hands on the handlebars at all times and lean slightly in the opposite direction so that the indicator can be seen better by vehicles behind you. The scooter does not have a hazard warning light function.

Errors

The control electronics of your SO4 2ND GEN / SO4 PRO / SO4 PRO 2ND GEN continuously checks the correct function of all important components. If your SO4 2ND GEN / SO4 PRO / SO4 PRO 2ND GEN detects a malfunction, this will be indicated accordingly on the display.
