SAFETY INSTRUCTIONS

3.1 GENERAL INFORMATION
Please read all safety instructions carefully. Failure to comply with the warnings or take residual risks into account may result in electric shock, fire and / or serious injury.
Keep the operating instructions in a safe place and have them readily available to consult. Pass these instructions on if you provide your e-bike for someone else’s use.
The generic names used in these operating instructions, such as motor, battery and operating element, all refer to original FIT e-bike components.
3.2 RECHARGEABLE BATTERY
Remove the battery from the e-bike before you start working on the e-bike (e.g. inspection, repair, fitting, maintenance, work on the chain), transport it by car or plane or if you are not going to use it for extended period of time.
There is a risk of injury if the e-bike system is activated unintentionally.
Do not open up the battery as you risk causing a short circuit.
Protect the battery from heat (e.g. including continuous direct sunlight), fire and being submerged in water. Do not store or operate the battery in close proximity to hot or flammable objects as this pose a risk of explosion.
Keep the unused battery away from paper clips, coins, keys, nails, screws or other metal objects which could cause an electrical arc between the contacts. A short circuit between the battery contacts can cause fire or burns.
Avoid any physical loads on the battery. They may inflict damage to the battery cells and cause flammable substances to leak out.
Do not put the charger and battery down next to flammable materials. Only charge batteries when they are dry and in a fireproof place. There is a risk of fire due to heat accumulating during charging.
The e-bike battery must not be left unattended while it is charging.
If the battery is used incorrectly, liquid may leak from it. Avoid coming into contact with the liquid. Rinse off with water in the event of accidental contact. If the liquid gets into eyes, seek medical attention. Leaked liquid can cause skin irritation and burns.
Vapours may be emitted if the battery is damaged or used improperly, ventilate with fresh air and consult a doctor if you suffer any pain or discomfort. The vapours can irritate the airways.
Charge the battery with original FIT chargers only. Risk of fire cannot be ruled out if non-original FIT chargers are used.
Use the battery in e-bikes with the FIT system only. This is the only way that the battery will be protected from dangerous overloading.
Only use original FIT rechargeable batteries which the manufacturer has approved for your e-bike. Using other batteries can result in injuries and risk of fire. FIT accepts no liability and offers no warranty if other batteries are used.
Keep the battery away from children.
Our e-bike rechargeable batteries are lithium-ion batteries which are developed and manufactured to the latest technical standards. Lithium-ion batteries have a high energy content when charged. In the event of a defect, possibly not visible on the outside, lithium-ion batteries may catch fire in very rare instances and under unfavourable conditions.

TRANSPORTATION AND STORAGE

5.1 TRANSPORTATION
CAUTION

• Remove battery before transportation.
• There is a risk of injury if the drive system is switched on unintentionally.

5.1.1 TRANSPORTING E-BIKES
Never use bicycle racks which use the e-bike’s handlebars or frame to hold the e-bike in an upside-down position. They can exert inadmissible forces on components during transportation. This can cause the supporting parts to break. The specialist dealer will advise you on how to select a suitable rack system properly and how to use it safely. Take the weight of the ready-to-use e-bike into account when transporting. Protect the electrical components and connections on the e-bike from the elements with suitable protective covers. Transport the battery in a dry, clean position where it is protected from direct sunlight.
5.1.2 TRANSPORTING THE BATTERY
Batteries are subject to hazardous goods regulations. Private individuals may transport undamaged batteries in road traffic. Commercial transport operators must comply with regulations on packaging, labelling and the transportation of hazardous goods. Open contacts must be covered and the battery securely packaged.
5.1.3 SHIPPING THE BATTERY
The battery is considered a hazardous good and only trained persons may pack and ship a battery. Contact your specialist dealer.
5.2 STORAGE
CAUTION

• Store e-bike, display, battery and charger in a clean, dry place where they are protected from sunlight.
• Do not store outdoors to ensure a long service life.
• The optimum storage temperature for your e-bike is between 10 °C and 20 °C.
• Temperatures under -10 °C or above +40 °C must generally be avoided.
• Store e-bike, display, battery and charger separately.

5.2.1 STORAGE MODE
The battery features a power-saving CHARGE TO STORAGE mode, which minimises discharge from the battery. Configure the CHARGE TO STORAGE mode in the battery settings.
5.3 BREAK IN OPERATION
NOTICE

• The battery discharges when not in use. This can cause irreparable damage to the battery.
• The battery must be recharged every 6 months.

The battery may become damaged if it is connected permanently to the charger. Never connect the battery to the charger permanently. If you remove the e-bike from service for longer than four weeks, you need to prepare it for a break in operation.
5.3.1 PREPARING FOR A BREAK IN OPERATION

• Remove battery from the e-bike.
• Charge battery to around 30–60% (storage mode).
• Before longer periods without use, it is recommendable to have your specialist dealer carry out an inspection and basic cleaning and apply preservative agent.

5.3.2 CARRYING OUT A BREAK IN OPERATION
Store the e-bike, battery and charger in a dry, clean environment. We recommend storing them in uninhabited rooms with smoke alarms. Dry locations with an ambient temperature between 10 °C and 20 °C are ideal. Check the battery level after 6 months. If only one battery level LED indicator lights up, recharge the battery to around 30–60%.
