1.5 Contraindications / Limitations
There are no known “contraindications” associated with the usage of the Mackworth SA400, provided they are used as per
manufacturer’s recommendations and guidelines. However, it is recommended that a client specific assessment is completed by
a trained and knowledgeable health care professional to determine the method of transfer.
Mackworth does not recommend a required number of care givers for the use of our products. This information and
recommendation can only be provided after a thorough personalised, case specific assessment, as there are many factors that
can influence these decisions.
1.6 Intended Use
For internal use only.
The Mackworth SA400 is a Standing Aid to be used by trained personnel. The Stand Aid is a medical device which
carries out safe lifting and transfers of an individual from one resting surface to another (such as a shower chair to a bed).
Mackworth recommends that the transfer of a patient is fully risk assessed and conducted safely over a short distance only.
Carrying out each transfer correctly for minimal strain or risk to the caregiver, while providing complete safety, dignity and
comfort to the client. The Mackworth SA400 is suitable for patients in the SITTING position only, who have a degree of weight-
bearing ability but require assistance to stand. By removing the foot tray, The Stand Aid can be used as a walking aid if
competent and trained person completes an adequate risk assessment of the surroundings, and the patient is observed during
use. The Mackworth SA400 is designed to support and promote safe patient handling and transfer for both the patient and
carer.
The Stand Aid is one of two components that makes this possible. The other component, the sling, is a specially designed fabric
accessory that attaches to the Stand Aid by means of the boom Loop attachment and straps, and holds the patient during
operation.
Please refer to the user guides supplied with the sling and reference them while reviewing this manual.
The functions of raising and lowering the boom, and opening/closing the legs are accomplished by pressing buttons on the hand
control.
The device is used under instruction and the operation of the aid is undertaken by a trained carer.

OPERATING INSTRUCTIONS
The Stand Aid may be heavy for users and will need to be lifted with care, please operate the device with the use of
the castors wherever possible to prevent any injury.
Appropriate training in lifting and handling procedures should be undergone by any person operating a Stand Aid,
for their own and the client’s safety and comfort. These instructions are designed to cover the method of using the Stand Aid.
5.1 Manoeuvring the Stand Aid
A. To move the Stand Aid forward, hold onto the handle bar and push forward.
B. Do not stand on the leg actuator, or use the actuator to push the Stand Aid (Fig. 10 and 11).
C. When turning the Stand Aid, use both hands on the handle. Alternatively, it is possible to rotate the Stand Aid by
applying the brake to a single rear castor and rotating the Stand Aid about the braked castor. This movement should be
performed with a smooth, slow action to avoid swinging the patient unnecessarily.
D. The Mackworth SA400 Stand Aid has two rear castors with brake.
E. The rear castors can be braked for rotation (by applying a single brake), lateral movement, and parking. To apply the
brake, press the brake pedal down with your foot (as shown in Fig. 12). To release the brake, press the raised pedal
towards the wheel (as shown in Fig. 13).
F. During lifting, the rear wheels should remain unlocked so that the Stand Aid will not move.
The wheels should be locked if there is a risk of the Stand Aid moving to the patient. For example, when lifting the
patient from the floor.
5.2 Raising and Lowering
The up and down movement of the lifting arm on the Mackworth SA400 Stand Aid is achieved by
an electric actuator which is controlled by hand control. The hand control has two buttons with
directional arrows up and down. The actuator stops automatically at the limit of travel in both
directions.
5.3 Open / Close Stand Aid Legs
The legs of Mackworth SA400 Stand Aid are opened/closed using the appropriate
buttons on the hand control, see figure 15 for guidance. The legs’ motion will be
stopped whenever the hand control button is released. The legs can be opened to
enable access around arm chairs or wheel chairs. When relocating the Stand Aid,
manoeuvring through narrow doorways and/or passages, the Stand Aid legs should be
in the closed position.

To resume power, release the emergency stop button by turning in a clockwise
direction (indicated by arrows on the Emergency Stop button) as shown in Fig. 17.
5.5 Mechanical Emergency Lowering
5.5.1 Manual Emergency Lowering
In case of power failure, it is possible to mechanically lower a patient placed in
Mackworth SA400 Stand Aid.
Turn the manual lowering handle in clockwise direction (as shown in Fig. 18) to
lower the boom until the boom reaches a safe position.
The manual emergency lowering system should be used only if the
lowering procedures described in the previous section of the manual
do not work. Should you have any concerns or questions contact your
local authorised Mackworth Representative.
Do not use the Stand Aid after the manual lowering mechanism has
been used. The lift must be reset by a qualified technician after use.
Contact your local authorised Mackworth Service Provider.
5.5.2 Electrical Emergency Lowering
The Stand Aid lifting arm can be lowered by pushing the emergency lowering button on
the control box with a suitable object, such as a pen nib or pencil (as shown in Fig. 19).
5.6 Handset Operations
The Hand Controls has 4 functions: Up and Down, this will raise and lower the Stand Aid lifting arm, and Legs
Open and Legs Close, these functions will open and close the legs.
Press down on each symbol to operate the desired function. It is not possible to use two functions at the same
time. Once the Stand Aid has reached the extent of its travel in a given direction, the actuator will
automatically stop, allowing you to then choose the opposite direction.
The handset is attached to the control box via a flexible, coiled cable that is secured in place with a friction-fit
plug. The coiled cable is designed to give the greatest number of options for carer positioning without having a
trailing cable around the patient. The handset also incorporates a hook which gives the carer flexibility whist
moving/positioning the patient. Clear and easy to understand labelling of the buttons enable ease of use for
the care giver.
The handset also displays battery level by the use of an LED light.
