Definitions Used in this Manual
Means: Failure to understand and follow these
instructions may result in injury to yourself
and others.
Means: Failure to follow these instructions
may cause damage to the product.
Means: This is important information
regarding the correct use of the equipment.
Intended Use
The Maxi Sky 440 is designed for lifting patients
in a homecare setting, at nursing homes and
other assisted living centers. Patient transfers
must be done under the supervision of trained
caregivers in accordance with the instructions
found in this manual.
The product must only be used for the reasons
stated above. It must be installed by
ArjoHuntleigh authorized personnel and in
accordance with local codes.
Operational Life
The product is designed and tested for a useful
life of seven (7) years or 10,000 transfers—
whichever comes first—when subject to
preventive maintenance as specified in the “Care
and Maintenance” section.
Time equivalence between the number of
transfers versus the number of years is made
clear in the table in Fig. 1.
The red indicator light on the portable lift will blink
when it is about halfway to its useful life, and
again to indicate the end of the useful life period.
The operating life of this product corresponds
directly to the safe operating time period before a
complete service is required.
Aging of the cassette, frequency of use (transfers
per day), the weight of the patient and
maintenance frequency are factors that have an
impact on the Maxi Sky 440’s life span.
A transfer is defined as the displacement of a
patient from one point to another. A transfer cycle
includes a lifting and a descending action.
The expected operational life for fabric slings and
stretchers is approximately 2 years from
purchase date. The life expectancy only applies if
the slings and stretchers have been cleaned,
maintained and inspected in accordance with the
“Preventive Maintenance Schedule.”
The expected life for other consumable products,
such as batteries, fuses, lamps, slings, straps and
cords is dependent upon the care and usage of
the product concerned. Consumables must be
maintained in accordance with published
Instructions for Use and the “Preventive
Maintenance Schedule”.
Product Identification
The unit's identification number (specification,
model, serial number) appears on a silver
nameplate affixed below the casing (see Fig. 17
on page 26).

Use of Slings
The 2 sling supports can accommodate any of the
ArjoHuntleigh loop attachment slings.
All slings are color coded for size by having a
different colored edge binding or attachment strap
coloring:
• Grey or Teal - Extra Extra Small - XXS
• White or Brown - Extra Small - XS
• Red - Small - S
• Yellow - Medium - M
• Green - Large - L
• Blue - Extra Large - XL
• Terracotta - Extra Extra Large - XXL
ArjoHuntleigh offers the option of a headrest for
many slings if it is considered necessary for a
particular patient. A range of special purpose
slings are available as accessories. For these or
for special size slings, contact your ArjoHuntleigh
agent.
Before Approaching the Patient
Attendants should always tell the patient what
they are about to do. Make sure to have on hand
a sling that is of the correct model and of
adequate size for transfer with the Maxi Sky 440.
Before performing the transfer, it is important to
evaluate the patient’s general condition. For
example, an agitated patient will require a more
specific type of sling.
Positioning the Patient
The specific sling loops chosen determine the
position of the patient. Different loop
combinations can be used to allow the patient to
be lifted and transferred in positions ranging from
semi-reclined to seated.
Attachment Methods
Once the loop sling has been fitted around the
patient, it can be configured in three ways. With
each of the three methods described below, it is
necessary to first connect each shoulder loop of
the sling to both sides of the spreader bar.
Attachments Points
The attachment point designation shown here are
only for the purpose of the explanations below.
Fig. 8
WARNING: All rails must be closed with end
stoppers or connected to other closed rail
components. Before use, make sure all end
stoppers are in place and secured. A wrong
installation of these items might lead to a
patient fall and to injuries.
WARNING: The lift must never be operated
by the patient. In the unlikely case of a
failure, the patient might get stuck in the
unit.
WARNING: When using ArjoHuntleigh Flites
slings (disposable) with the Maxi Sky 440,
always refer to the ArjoHuntleigh Flites
operating instructions as well as these
instructions before using.

Method 1 - Cross-through
(Legs closed with crossing straps)
This method is recommended for most general
transfer (see Fig. 9).
Fig. 9
Method 2 - Hammock
(Bridge, legs closed)
This method can provide a comfortable cradle for
amputee patient.
It is also a useful method for patients with
contractures, making it difficult to bring a sling
strap between the legs (see Fig. 10).
Fig. 10
Method 3 - Abduction
(Legs opened with non-crossing straps)
In this method, legs are held in abduction which is
convenient for toileting and hygiene care (see
Fig. 11).
Fig. 11
Transferring the Patient
To begin the transferring procedure:
1) Install the patient into the sling according to the
“Installing a Patient into the Sling” section.
2) Unwind the strap by pressing the DOWN
button on the hand control while holding a
tension on the strap with the other hand.
3) Attach the carabiner to the trolley and then
move the lift over the patient.
4) Lower the lift below the chin and unfold
supports before attaching the sling straps.
(This will prevent the lift from striking the
patient’s face due to the lift’s movement).
5) To attach the sling, unfold the support on each
side of the lift. Insert the strap loop onto the
support and pull gently on the strap.
6) The support safety latch will rotate allowing the
strap to slide into the hooks. The strap will be
trapped inside the support as the safety latch
will automatically revert to the closed position.
Do not attempt to transfer a patient if the safety
latches are not blocking the support’s opening
for the strap.
Fig. 12
WARNING: This method might not be
suitable for confused, combative or erratic
patients as they can fall forward and get
injured.
WARNING: This method might not be
suitable for patients with no upper body
control as they can slide down and almost
out of the sling.
Note: There must be tension on the strap for
the lift to function.
Note: For a patient in a supine position,
lower the lift near the chest, unfold supports,
then install the straps.
NOTE: The back of the sling has sewn
handles to allow better positioning for the
caregiver and enhancing patient safety.

7) To lift the patient, press the UP button on the
hand control.
8) Lift the unit until the patient's buttocks clear the
arm supports of the wheelchair, the top of the
bath or the bed before moving the patient.
Guide the patient’s legs past any obstacles.
Fig. 13
9) When the patient is located above the desired
point of transfer and ready to be lowered,
press the DOWN button.
10)Once the patient is properly seated, loosen the
straps and disengage the sling from the lift.
11) Slide the lift away from the patient. Unhook the
lift from the trolley and use the hand control to
shorten the strap. You can now remove the
sling from around the patient.
12)When the Maxi Sky 440 is no longer required,
plug the portable lift back to the charger.
Emergency Shut-off
The operator can shut off the electrical power at
any time by pressing the red mushroom-shaped
emergency button under the lift. The button is
reset by twisting it clockwise in the direction of the
arrows. First time users should practice the shut-
off manoeuvre before operating the lift with a
patient.
Emergency Lowering
The Maxi Sky 440 has a special safety feature
that allows the lift to be lowered even if the
electrical system does not operate.
Located on the right side of the lift (near the
folding sling support), the emergency lowering
device is activated by the insertion of the special
tool included with this manual.
To lower safely a patient, follow these steps, as
illustrated in Fig. 14:
1) Press on the red, emergency shut-off button
under the lift. Move the lift with the patient over
the bed or the wheelchair.
2) Remove the plastic cap covering the
emergency lowering mechanism’s entry.
3) Insert the special tool into the opening. Turn it
clockwise to lower the patient. The tool rotation
turns the motor directly, so that for each tool
turn, the patient will lower slightly. Once the
patient is lowered safely on a bed or into a
wheelchair, remove the tool from the lift. Call a
qualified technician to service your
Maxi Sky 440.
WARNING: Before lifting the patient:
1) Make sure that all straps are attached to
the lift’s supports.
2) Make sure the patient's arms are safely
out of the way.
3) Make sure the sling is not caught on any
obstructions (wheelchair brake or chair
arm, etc.).
If any of the above occurs, lower the patient
immediately and correct the problem. Any of
these situations might lead to a patient
falling.
WARNING: Hold the ceiling lift spreader bar
with one hand at all times when near a patient
to avoid risk of contact.
WARNING: Constant attention to the patient
is required from caregiver during the whole
transfer. In the unlikely event of a failure of
the device, the caregiver must be ready to
react.
CAUTION: The emergency lowering feature
is to be used only in case of emergency.

18
How to Use the Maxi Sky 440
001.16000.33.EN rev. 14
Emergency Brake
The emergency brake is an additional safety
feature that automatically prevents the patient
from falling in the unlikely event of a transmission
or motor failure.
WARNING: After an incident has occurred
and the brake was deployed, never attempt
to unlock the brake or press the UP button.
This may disengage the brake and make the
patient fall. The emergency lowering device
cannot be used.
WARNING: Never use a portable lift with the
emergency brake deployed. Use other
equipment to lower the patient. Forcing the
lift to make it move might lead to patient fall.
The emergency brake is intended for a
single activation and therefore can only be
used once. Call your ArjoHuntleigh agent for
replacement of the unit.

Only use batteries designed and labelled for use
with the device. When not sure, do not use the
battery. Make sure the battery belongs to the
device by comparing the battery label with the
technical specifications in this manual. If battery
type cannot be confirmed, call your ArjoHuntleigh
agent.
Battery life depends on many factors. These are:
frequency of use, frequency of charging,
temperature of operation, storage and storage
time.
Using lead-acid batteries below a 20% charge
can damage the battery resulting in shorter
battery life.
Make sure to have a replacement battery ready
when needed. Have the facility department keep
one in stock.
The batteries included in the Maxi Sky 440
provide 10 to 30 transfers per battery charge.
Charging the Batteries
The steps for recharging the batteries are as
follows:
1) Plug the charger into a wall socket compatible
with universal voltage input from 100 Vac to
240 Vac.
2) Plug the charger’s DC connector to
Maxi Sky 440 DC inlet.
3) The charge indicator blinks yellow while the
battery is charging. When batteries are fully
charged, the charge indicator will turn solid.
The unit is ready to use (see Fig. 5 on page
page 12) .
4) If the battery is low, it will take approximately
2 hours for a full charge.
When you need the lift again, unplug the charger.
The charger can remain plugged to the lift
indefinitely, which is convenient for overnight
charging. The lift can be charged for an extended
period of time without damaging either the
charger or the batteries.
If the batteries have been completely drained it
could take up to 6-8 hours to completely recharge
them. In order to reduce the charging time, refrain
from completely draining the batteries and leave
the portable lift connected to the charger between
uses.
WARNING: Not following these instructions
can result in a short battery life.
NOTE: To prolong battery life, plug the
charger to the lift’s DC charger inlet
whenever the portable lift is not in use. If the
low battery indicator beeps, make sure to
recharge the batteries as soon as possible.
Charge the batteries until the charging
indicator light is a solid yellow before using
the lift again. This will extend their life.
NOTE: ArjoHuntleigh uses sealed lead-acid
batteries. These ones are not affected by
any memory effect. Therefore, they should
not be completely drained before
recharging.
WARNING: Do not operate the charger with
a damaged cord or if the lift has been
dropped or damaged. Do not bend the power
cord by force, or place a heavy object on it.
These could damage the cord and may
cause fire or electrical shock.
NOTE: The lift cannot use energy from the
charger to operate. If you try to activate any
function of the lift when plugged to charger, no
command will be activated.
NOTE: If the charge indicator does not go on or
blink when the charger is plugged to the lift’s
DC charger inlet, see the “Troubleshooting”
section.
CAUTION: Do not attempt to use a battery
that was not supplied by ArjoHuntleigh.
These batteries are specially designed for
ArjoHuntleigh charging systems. Attempting
to use an unapproved battery may seriously
damage the lift and/or the charger.
