Preparing The Product For Use; Activating The Circuit Breaker; Charging The Batteries - Otto Bock C1000 SF Instructions For Use Manual

Storage conditions
• Store the power wheelchair in a dry, enclosed room with sufficient air circulation and protection from external
influences. Specific information about storage conditions: see Page 18.
• Protect the wheels against ground frost, for example by taking all weight off them using an assembly stand or
by setting them onto wooden blocks.
• Maintain sufficient clearance from sources of heat. If the product is parked for an extended period of time or
the tyres overheat (e.g. in the vicinity of radiators or in case of exposure to strong sunlight behind glass), the
tyres may become permanently deformed.
• Fill pneumatic tyres with slight overpressure.
• Rotate the wheels weekly to prevent flat tyres from extended standing.
• For extended storage, store the power wheelchair so the wheels are not in contact with the ground.
Note regarding the tyres
• If the power wheelchair is not moved for several days, permanent colour changes may develop where it comes
into contact with the ground. A suitable base should therefore be used when parking it for extended periods of
time.
• Black tyres contain carbon black particles. They may leave black friction marks where they come into contact
with the ground. Therefore, the manufacturer recommends grey tyres if the product is primarily used indoors.
• Avoid unnecessary parking outdoors. Direct exposure to sunlight/UV radiation causes the tyres to age more
quickly. As a result, the tread surface hardens and corner pieces break out of the tread.
The tyres must be changed when the tread is less than 1 mm (0.04") to ensure safe driving behaviour.
•
• The tyres should be replaced every 2 years regardless of wear and tear.
• When power wheelchairs with PU tyres are parked for longer periods, the tyres may become deformed (flat
spots). This deformation will go away on its own over time while driving.

5 Preparing the product for use

CAUTION
Short circuit of the battery
Burns due to incorrect battery installation, damage to the electrical/electronic components
► Deactivate the circuit breaker before performing any work on the battery.
► Only use insulated tools to perform maintenance work on the batteries.
► Ensure correct polarity when you connect the battery cables. Connect the black cable to the negative terminal
and the red cable to the positive terminal.

5.1 Activating the circuit breaker

The automatic circuit breaker has to be activated before the power wheelchair can be switched on.
See the power wheelchair instructions for use (user) for more detailed information.

5.2 Charging the batteries

WARNING
Incorrect charging or use of the battery
Injuries due to fire or explosion, damage to the battery, short circuit
► Observe the safety notices in the instructions for use (user), section "Use" > "Batteries/charging process".
WARNING
Insufficient ventilation of the battery charger while charging
Burns due to the battery charger overheating/catching fire
► Make sure the battery charger cannot overheat during the charging process.
► Ensure that the cooling fins/ventilation slots on the back of the device are not covered.
CAUTION
Wearing of unsuitable work clothing
