Introduction
Intended use
The Maxi Sky
440
is intended for lifting residents at
acute care hospitals, elderly care facilities and other
health care facilities under the supervision of
appropriate trained caregiver staff in accordance with
the instructions outlined in this Operating and
Product Care Instructions. All other uses must be
avoided.
The equipment must only be used for the purposes
stated above, and must be installed by ARJO
authorized personnel and in accordance with local
codes.
Operational life
WARNING:
The manufacturer cannot ensure full safety
for a ceiling lift or an accessory of which the
lifespan is exceeded.
The equipment is conceived and tested for a useful
life of 10 000 transfers, 3 to 7 years, whatever comes
first, subject to preventative maintenance as specified
in the Operating and Product Care Instructions, the
Assembly and Installation Instructions and the Spare
Part Instructions. Time equivalence between number
of transfers / number of years is made clear in the
table in figure 1. The red indicator on the ceiling lift
will blink for a while when it is halfway to its useful
life, and again to indicate the end of the useful life
period.
The operating life of this equipment corresponds
directly to the safe operating time period before a
complete overhaul is required. Age of the cassette,
frequency of use (number of beds / transfers per day),
resident weight and maintenance frequency are
factors that have an impact on the Maxi Sky
440
lifespan. A transfer is defined as the displacement of
a resident from one point to another. A transfer cycle
includes a lifting and a descent action.
The expected operational life for fabric slings and
fabric stretchers is approximately 2 years from date
of purchase. This life expectancy only applies if the
slings and stretchers have been cleaned, maintained
and inspected in accordance with the “ARJO Sling
Information” documents, the “Operating and Product
Care Instructions” and 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
equipment concerned. Consumables must be
maintained in accordance with published “Operating
and Product Care Instructions” and the “Preventive
Maintenance Schedule”.
Equipment identification
The unit's identification number (specification,
model, serial number) appears on a silver nameplate
attached at the end of the lift.
Verifying the package contents
Always ensure that the ceiling lift shall be installed
by an ARJO authorized contractor or installer.
Upon receipt of the equipment, verify it against the
packing list to ensure it is complete and inspect the
equipment for possible damage due to shipping. If
there is any damage, notify the carrier immediately to
file a claim. Provide complete information
concerning damage claims or shipping errors to your
local ARJO representative. Include all equipment
identification numbers and group part numbers (if
any) as described above along with a full description
of damaged parts.

How to use the Maxi Sky
440
WARNING:
Always read the Safety Instructions before
using the Maxi Sky
440
.
NOTE!
Always carry out the daily checklist before
each lift use.
Operating the Maxi Sky
440
is simple and requires
little instructions. By using the lift, an operator is
able to raise, transefer and lower the resident safely.
C A U T I O N
The Maxi Sky
440
should not be used in
conjunction with any resident slings other
than the Ergofit slings that are especially
designed for the system. The manufacturer
disclaims any responsibility for improper
use employing any other sling.
NOTE!
Instructions provided here are described
from the operator´s point of view, i.e. when
positioned in front of the lift and ready to
transport the resident.
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 a half-turn clockwise in the direction of the
arrows. First time users should practice the shut-off
manoeuvre before operating the lift with a resident.
See figure 1.
Emergency lowering
The Maxi Sky
440
is equipped with 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
key included with this manual.
To lower safely a resident, follow these steps:
1 Press on the Emergency shut-off red button under
the lift. See figure 1.
2 Move the lift with the resident over the bed or the
wheelchair.
3 Remove the plastic cap covering the Emergency
lowering entry. See figure 2.
4 Insert the special key into the opening then turn it
clockwise to lower the resident. See figure 3. The
key rotation turns the motor directly so for each
key turn, the resident will lower slightly. Once the
resident is lowered safely on a bed or into a
wheelchair, remove the key from the lift and call
a certified technician to service your Maxi Sky
440
.
Battery information
The batteries included in the Maxi Sky
440
are
12 VDC, 2.3 Ah and rechargeable. They provide
10 to 30 transfers per battery charge.
NOTE!
The number of transfers may vary
depending on the resident weight and the
batteries condition.
NOTE!
To prolong the batteries life, plug the
charger to the lift whenever the lift is not in
use. Do not worry, the batteries will not
overcharge.
The manufacturer uses sealed lead-acid batteries.
Contrary to nickel-cadmium, the batteries do not
have any memory effect. Therefore, batteries should
not be completely drained before recharge.

How to use the Maxi Sky
440
C A U T I O N
Do not drain batteries excessively. This will
dramatically reduce the batteries life span.
If the low battery buzzer sounds, be sure to
recharge the batteries as soon as possible.
Charging the batteries
Plug the charger into a wall socket compatible with
universal voltage input from 90 Vac to 240 Vac.
See figure 4.
Check to make sure the green light on the charger
is illuminated. This indicates that the charger is on.
Plug the charger DC connector to Maxi Sky
440
DC
inlet.
The charger indicator light turns yellow while the
battery is charging. When batteries are fully charged,
the charging indicator light will turn off. The unit is
ready to use.
If the battery is low, it will take approximately
2 hours for a full charge.
NOTE!
Connect the charger to the lift when the lift is
not in use. At minimum, charge the batteries
until the light is yellow before using the lift
again. This will extend the life of the
batteries.
When you need the lift again, pull out the charger
plug from it.
The power cord can remain plugged into the wall
indefinitely, convenient for overnight charging.
The charger can either be installed on the wall or
be free. If you install it on the wall, the back of the
charger is designed to be clipped on screws head.
The lift can be charged for an extended period of
time without damaging either the charger or the
batteries.
NOTE!
If the green indicator light does not go on
when you plug the charger into an electrical
outlet, see the "Troubleshooting" section
included in this manual.
WARNING:
Do not operate the charger with a damaged
cord or if the units housing has been
damaged.
Do not forcibly bend the power cord or place
a heavy object on it. This will damage the
cord and may cause a fire or an electrical
shock.
Do not attempt to use a battery not authorized by
the manufacturer. The Maxi Sky

system use specially designed batteries by the
manufacturer. Using unauthorized batteries may
seriously damage the lift or the charger.
The lift should not remain stored for long period of
time without charging the batteries.
