Congratulations on your choice of Invacare® EC-Høng’s SB750

TM

nursing bed.

x The bed has been developed for patients over 12 years of age requiring care in a nursing home or

home care nursing.

x The bed combines excellent stability and ergonomic design with easy disassembly and operation.

x The unique backrest return of the bed provides the patient with excellent comfort and the carer with ideal

conditions for an ergonomically correct working position.

In order to optimise the patient’s comfort, Invacare® recommends using a 12-cm mattress.

1. General information

The SB750

TM

bed fulfils all requirements regarding maximum distances. However, if the bed

is used for the care of patients with small body dimensions, it must be especially noted that there

is a risk of such a patient slipping through the openings between the side rails or through the

opening between the side rail and the mattress support.

The bed must not be used by patients under 12 years of age, or by patients with body size

equivalent to an average 12 year old or smaller.

The bed, in combination with side rails, must not be used for persons under 45 kg or under 150

cm´s height, or for persons that are restless (spasms) or confused, unless

 a professional risk assessment has taken place and been accepted, or

 a correctly installed safety cover on the side rails are used.

When using side rails and the according safety cover, it is essential to ensure correct fitting -

otherwise there is danger of entrapment / suffocation between mattress support, side

rail and bed end!

If the bed is used by restless (spasms) or confused persons, an ACP box can be used for blocking

the hand control functions, and / or a limitation cross bar installed under the leg section of the

mattress support. This cross bar will prevent the leg section from being lowered below the level of

the mattress support, thereby reducing the opening between leg section and bed end.

Ensure the bed is adjusted to it’s lowest position before leaving the bed unattended - thereby the

effect of fall-down / entrapment accidents is reduced.

Invacare® accepts no liability for any use, change or assembly of the product

other than as stated in this User’s Manual.

When entering or exiting the bed, the height adjustment should be used. Furthermore, the backrest can be used as

support (yellow button on the hand control). However, the thigh- and leg section must be horizontal, otherwise,

there is risk of overloading of the mattress support.

The bed must be placed so that the height adjustment (up/down) is not obstructed by, for example, lifts or

furniture. Otherwise there is a risk for injury on user and/or equipment.

1)

Operating the leg section on beds with gas springs

Lift the handle with one hand, while adjusting the leg section to the desired position with the other hand.

Release the handle.

Operating the leg section on SB750, 120 cm width, with Rastofix

To raise the leg section: Lift the leg section to desired height.

NB: Please ensure that both Rastofix brackets are correctly locked in place.

To lower the leg section: Lift the leg section slightly and lower to horizontal.

Always leave the bed in the lowest position. Otherwise there is a risk of squeezing due to

accidental lowering of the mattress support. A person can be seriously injured under the bed

during height adjustment.

Operating the braking castors

Operating castors without central braking system

When the bed is positioned correctly, at least one castor at the head end and one

castor at the foot end must be locked.

1) Braking: Step on the pedal.

2) Releasing the brake: Step on the release pedal.

Operating castors with central braking system

When the bed is positioned correctly, it must be locked.

1) Braking: If the brake is in neutral, step on the red pedal.

2) Releasing the brake: Step on the green pedal, until the brake is in neutral

position.

Operating the steerable castor

The SB750

TM

with central braking system may be equipped with a steerable castor.

The steerable castor is operated by means of the central braking pedal.

1) Activating the steering: If the brake is in neutral, step on the green pedal.

2) Deactivating the steering: Step on the red pedal, until the brake is in neutral

position.

Set-off from the castors might under special conditions appear at different types of absorbing floor covering -

including untreated or badly treated floors. In matters of doubt, Invacare® recommends to place a suitable kind of

protection between the castors and the floor.

side rail away from the locking mechanism.

There is risk of entrapment of fingers on assembly and operation of the side rails.

Please ensure that the side rail locking system has engaged properly by pulling / pushing the upper bar.

Adjusting the height of the lifting pole handle

Loosen the cord as shown in fig. A. The lifting handle can now be

adjusted to the desired height.

Press the cord together as shown in fig. B and check that the cord

is locked in the cord lock by pulling the handle.

Position the lifting pole in such a way that the

handle is above the bed. If the lifting pole is used

while the handle has been turned away from the

bed - the bed can tip when the handle is used.

9. Maintenance and check-ups

Service and maintenance of the SB750

TM

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.
