It is recommended that the User Manual be kept in an easily accessible
place for quick reference. If required Aidacare product specialists can
provide additional training.
All warnings and cautions within this manual should be strictly adhered
to. Failure to do so could result in harm to the patient or operator.
Warnings highlighted throughout this manual identify possible hazards
in procedures or conditions which if not followed correctly could result in
serious injury, or fatality.
Cautions highlighted throughout this manual identify possible hazards

GENERAL
• Electrical equipment can be hazardous if used incorrectly.
• Residual current devices (RCD) are not supplied with the AC4 beds.
Please consult with your Biomedical Engineer/advisor concerning
RCD requirements.
• The clinically qualified person responsible should consider the age, size
and condition of the patient before using the bed and its accessories.
• The maximum safe working load of the AC4 beds of 220kg includes the
mass of the patient, mattress and any accessories fitted to the bed.
• Maximum mattress thickness that can be used on the AC4 beds is 170mm.
• Side rails must only be used with a mattress of appropriate size, which
is approved for use with the bed.
• If a patient’s condition could lead to a possible entrapment the mattress
support platform should be left in the flat position whilst unattended.

6 7aidacare.com.au
• ALWAYS position the bed at its lowest height when unattended by
caregivers to minimise the risk of patient injury from falls when getting
in and out of the bed.
• ALWAYS use a mattress of appropriate size and type. A range of
suitable pressure reducing and pressure relieving mattresses are also
available from Aidacare.
• ALWAYS make sure that the patient is safely positioned to avoid
entrapment before operating the bed.
• ALWAYS ensure that attendant and patient limbs are free from
potential entrapment areas before operating any functions.
• ALWAYS ensure that the bed is at a suitable height to avoid stooping
or straining before transporting.
• ALWAYS apply the brakes when the bed is stationary.
• ALWAYS store the handset when not in use to avoid accidental
operation of the beds functions. The handset can be stored by hooking
it on to the side rail of the bed.
• ALWAYS ensure that all hospital lines and power cables are free from
possible entanglement with mechanical parts of the bed.
• DO NOT place the handset, or power cord across the mattress surface
of the bed when the bed is not connected to mains power. Always store
the power cord within the power cord fixtures fitted to the bed.
• DO NOT use electrically operated beds in operating theatres.
• DO NOT use electrically operated beds in the presence of flammable gases.
• DO NOT use the bed to support more than one patient. AC4 beds
are intended for single person use and may become unstable if
used incorrectly.

4.2 BED EXTENSION
The integrated bed extension can add an extra 200mm of length
to the mattress platform.
MOVING BED EXTENSION FROM CLOSEDSTANDARD
BED POSITION
1. The bed extension is held in position by two threaded hand wheels
on either side of the bed. Unscrew (anti clockwise) the hand wheels on
both sides. It is not necessary to remove the hand wheels completely,
unscrewing them by approximately 10mm of thread length will allow for
the internal lock nut to travel freely past the thread of the hand wheel.
2. With both hand wheels now unscrewed, gently pull with an even
force on both sides of the bed end. (2) Indicates the best position for
easier extension if used on both sides of the panel at the same time.
3. Lock hand wheels in place on either side to lock bed end in.
4. Return the hand wheels back to their locked position (1)
To reposition the bed end back to the closed/standard bed position
use the same technique as above.

WARNING: The bed extension is designed for use as a bed extension
only and is not meant to support the body weight of a person sitting.
The extra length of the bed with extra load can also make the bed
unstable potentially resulting in injury to the user and patient.
4.3 FOLD DOWN SIDE RAILS (OPTIONAL)
Bed rails (optional) are easily fitted by clamping to the bed frame.
When fitted correctly, AC4 bed rails meet the requirements of Medical
equipment international standard IEC 60601-2-52, which includes specific
rail requirements.
4.3.1 FITTING THE SIDE RAILS
NOTE: The rails are a left and right hand set and when fitted correctly fold
down towards the foot end of the bed.
1. Before fitting the rails unscrew the hand wheel to bring the locking
clamp into an open neutral position which will allow the rail to fit over
the side rail of the bed.
Closed Position Open Position
2. With both hand wheels now unscrewed, lift the rail into position. It
is important that the rails are fitted to a specific position on the bed,
which is indicated by the bolt on top of the bed frame. Position the
rail over the bolt and tighten the hand wheel to the closed position.

12 13aidacare.com.au
4.3.2 SIDE RAIL OPERATION
The rails are either fully raised, or folded down closed. When the side rail is
raised to its full height position it will automatically lock in the positioning
hole on the rail clamp plate. The release/lock knob feature can be both
visually and audibly confirmed.
WARNING: Do not operate side rails when there is potential of entrapment
or crushing to the patient, caregivers, visitors and/or other equipment.
Side Rail Operation
To raise the side: Lift the top rail until the locating
pin/knob automatically clicks into its locked
position at maximum height.
To lower the side: Hold the top rail near the foot
end of the bed (1) and gently pull out the red
operating knob (2) lowering the side towards
the foot of the bed whilst controlling the descent
speed. As the side begins to be lowered the
operating knob can be released.
WARNING: Care should be taken whilst operating
the side rails to ensure hands and fingers are kept
away from potential squeeze hazards. Side rails
should only be used after clinical assessment and
within organisational policy and guidelines.
4.3.3 SIDE RAIL SAFETY LOCK INDICATOR
The side rail locating pin has a yellow coating
that allows for visual inspection of the locking
device. When the side rail is in the raised position,
viewing the release knob from the side there
should be no yellow shaft visible. If there is yellow
shaft visible the safety side is NOT securely locked
in the upright position and needs to be adjusted.
The yellow coating should NOT be visible from
above when the safety side is correctly locked
in position.

WARNING: After adjustment of the side rail visually check the locking
pin location. There should be no yellow shaft on the locking pin visible if
locked correctly. DO NOT use other manufacturer’s side rails on AC4 beds.
4.4 KING SINGLE EXTENDABLE FOOT END MATTRESS RETAINER
AC4 beds come standard with an extendable foot-end mattress-retainer
that is used in conjunction with the bed extension.
To extend the mattress retainer hold vertically and insert ends into 1 of
the 3 receiving keyhole mounts which are 100mm spaced at the foot end
of the mattress platform to match the desired bed extension (nil, 100mm,
200mm). Lower the retainer to the mattress platform. It will now be locked
