9. Maintenance and check-ups
TM
Service and maintenance of the SB750
must only be performed by personnel who have received the
necessary instruction or training.
With normal daily use, service must be carried out according to the service schedule after 2 years use and
thereafter every second year.
When moving the bed, service must be carried out according to the service schedule.
When using Flex or Karin bed ends, which are made of a flexible type of wood, it will be necessary to tighten the
hexagon head screws at intervals other than described in the service schedule.
Note! The top frame must be supported during service inspections to prevent accidental lowering.
We recommend a safety test comprising the motors' performance and mechanical state once a year.
Motors, hand control and control unit
These parts are serviced by exchanging the faulty part.
10. Beds equipped with accumulator back up
A bed with accumulator back up is equipped with an additional box next to
the control unit.
Preventive maintenance
The accumulators have to be exchanged after 4 years. Depending on how the
back up is used the exchange may have to take place earlier.
Frequent, sudden discharges reduce the back-up's life.
We recommend the accumulator be tested at least once a year.
Accumulators are not damaged by continuous connection to the mains.
Exchanging the accumulators
Accumulators must be exchanged as sets and replaced with accumulators of the same type or mechanically
and electrically compatible accumulators:
The accumulators are delivered as a pair under order no.: 818323 (12V - 1,2 Ah).
Accumulators must be new and charged at least every 6 months for maintenance purposes.
Accumulators in a set must have identical production codes.
Prior to insertion make sure that the accumulator set is correctly connected cf. the drawing
(in the accumulator box), and that none of the connections are loose.
Warning
Old or faulty accumulators may generate an explosive gas mixture during charging.
The accumulator box is provided with vents to ensure adequate ventilation of the box.
The vents must not be blocked or covered, as this may result in pressure built-up and the risk of explosion.
Waste disposal
®
Old accumulators may be returned to Invacare
, alternatively they are disposed of like car batteries.
