2.5 Safety Instructions for Maintenance Works on Electrical Components

WARNING
Risk of acid burns caused by battery acid. Batteries must not be tilted, as this would allow very caustic
battery acid to leak from the gas venting holes. Always wear protective gloves and safety glasses when
working on the batteries. In case of contact with the skin or eyes, take the following first aid measures:
• After skin contact or splashes on clothes, immediately neutralise with acid converter or soap and
rinse with plenty of water.
• After eye contact, immediately rinse the eye under running water for a few minutes, then consult a
medical specialist immediately.
• After swallowing, consult a medical specialist immediately.
CAUTION
Risk of injury while working on the battery. Only use a battery charger supplied by Otto Bock which
has been tested and approved for the respective batteries by Otto Bock (observe information on the
charger). Failure to do so can result in a battery explosion and possible impairment of health due to
contact with battery acid.
Smoking and open flame are prohibited while working on the battery. Sparks must be avoided.
Explosive gases can develop while the batteries are charging. Observe the safety information provided
by the battery manufacturer. Wear protective goggles. Ensure sufficient ventilation when charging the
batteries in an enclosed room.
Drive batteries can supply very large amounts of energy and may arc if they are short-circuited. There-
fore, always disconnect the batteries when working on the motor control or wiring.
NOTICE
Risk of damage due to improper preparation of maintenance tasks.
If the driving function is not required, turn off the control unit or jack up the drive wheels in order to
prevent uncontrolled operation through accidental joystick activation.
• Water must not come into direct contact with the electronics or battery during maintenance tasks.
• When attaching plug connections on the controller, ensure the contacts are assigned correctly.
NOTICE
Risk of battery damage. In order to prevent short circuits, always use insulated tools when working
on the batteries.
Prevent deep discharge of the batteries in order to avoid loss of functionality and permanent
battery damage.
Ensure correct polarity is used when connecting the batteries.
NOTICE
Risk of damage to the battery charger. Prevent overheating of the charger during the charging proc-
ess. Ensure that the cooling ribs on the back of the device are not covered.
