Hand Control
The hand control has an integrated hook which makes it easy to
attach. When not in use, hook it over the hand control hang point
at the top of the mast (B) or the hand control holder located on the
main lift actuator (A). (See Fig. 1)
Unhook the hand control and hold it in your hand:
• Press (A) button in order to raise the jib. (See Fig. 2)
• Press (B) button in order to lower the jib. (See Fig. 2)
• Press (C) button for reclined position (only for powered
spreader bar). (See Fig. 2)
• Press (D) button for sitting position (only for powered
spreader bar). (See Fig. 2)
• Press (E) button to close chassis legs.
(See Fig. 2)
• Press (F) button to open chassis legs.
(See Fig. 2)
Lifting
The lifting/lowering movement is performed by an actuator driven
by an electric motor.
Adjustable Width of Chassis Legs
The chassis legs can be opened to variable widths.
Select the “Open chassis legs” button on the hand control and
keep pressing it until the required width is achieved.
To close, press the “Close chassis legs” button. When pressure is
released from the button, movement will stop and the chassis legs
will remain securely in position.
(See Fig. 3)
CAUTION

Emergency Stop Button
In case of an emergency, where you immediately have to stop any
powered movement, (other than by releasing pressure on the hand
control button), press the “emergency stop button”(A), located on
the side of the main lift actuator cover (see illustration).
(See Fig. 1)
Once the emergency stop button has been operated, it will have to
be reset before any powered movement can be utilised.
To reset the emergency stop function, turn the red emergency
button 1/8 of a turn clockwise until it pops up.
Emergency Lowering “Ring”
The emergency lowering function will only work when there is a
load in the Maxi Twin lift exceeding 2 kg (4.4 lbs). It can be used
in the event of a main control failure.
The emergency lowering “Ring” (B) is on the top of the main lift
actuator housing, a green and white identification label is
positioned near the emergency lowering ring for quick and easy
recognition. Pull the emergency lowering ring up to operate,
release the control during use and lowering will stop. (See Fig. 1)
WARNING
To avoid injury, only use the emergency lowering
when normal lowering is impossible. Use extreme
care during lowering.
NOTE
Due to internal friction, the speed of lowering will vary
depending on the weight of the resident. You may have
to assist the downwards movement by pulling down the
jib
NOTE
The emergency lowering overrides important safety
functions and should only be used when the hand
control is not working.

Powered Spreader Bar
Four sling attachment lugs (A) enable the sling clips to be
attached.
The rotational positioning handle (B) allows you to position the
resident sideways.
The powered spreader bar (C) is operated from the hand control.
The resident can be positioned in a reclined or sitting position.
(See Fig. 1)
Automatic Safety Stop
This is not operator controlled but a function built into the
electronics of the lift.
Battery
The battery is situated on the side of the lift actuator housing.
(See Fig. 1)
Battery Indicator Light
A beeping sound and a low battery indicator (A) light will flash
when the battery needs charging. The caregiver should complete
the current lift movement. (See Fig. 1)
Battery Charger
Type no:
NEA 8000
(See Fig. 2)
Function I:
If the lift is moving up /down and it moves against
something, the movement will be stopped by an
automatic safety stop. Release the up /down button on
the hand control.
Function II:
If the lift is mistakenly overloaded with a resident
heavier than permitted, an automatic safety stop will
automatically be activated. If this occurs, stop pressing
the up button on the hand control. Lower the resident by
pressing the down button and then remove the resident
from the lift.
NOTE
The battery shape only fits correctly into the lift with its
raised edge upwards.

Powered Spreader Bar (if fitted) (2 Steps)
If your lift comes with a powered spreader bar, the same
instructions apply as the non-powered spreader bar.
1 The difference is that the powered spreader bar has the
added advantage of positioning the resident with minimal
physical effort by the caregiver. The rotation of the powered
spreader bar is manual which is the same as the manual
spreader bar. (See Fig. 1)
The powered spreader bar is waterproof and is classified
labelled by ArjoHuntleigh as a wet environment unit. This
water level mark signifies that the lower end of the spreader
bar and sling may be immersed in bath water or used for
showering.
2 In orderto position theresident, move thepowered spreader
bar by a push of a button on the hand control. The
movementwill stopwiththe releasedpressure ofthe button.
The spreader bar will remain firmly in position, once
powered movement has stopped. (See Fig. 2)
WARNING
To avoid falling, make sure that the user weight is
lower than the safe working load for all products or
accessories being used.
CAUTION
The electrical actuator, as part of the powered
spreader bar, will not withstand water and should
not be sprayed with water or be submerged under
water. The maximum water level is indicated on the
water level mark on the side of the spreader bar.
WARNING
To avoid entrapment, make sure the path of the
movement is free from obstacles.

Before the resident is transferred to a Maxi Twin,
make sure that:
• the battery pack is fully charged before use. Remove it from
the charger unit and the arched top of the battery should face
upwards when inserted into the battery opening. Electrical
connection will be made automatically.
• aselectionof slingtypesand sizesare easily availablefor all
types of lifting procedures when using the Maxi Twin lift.
• when possible, approach the resident from the front.
• if necessary, open the chassis legs to go around a chair or
wheelchair.
Powered Chassis Legs
Select the appropriate button on the hand control and keep it
pressed down until the required leg width is achieved. To close,
press the close chassis leg button. The opening/closing of the
chassis legs will stop if pressure is released from the button.
When to Use the Brakes
When lifting or lowering a resident who is supported by a sling it
is not necessary to use the brakes. This allows the lift to move to
the correct position relative to the centre of gravity of the resident.
It’s recommended to apply the brakes however, when lifting a
resident from the floor. This may prevent any unwanted or
accidental movement of the Maxi Twin lift that may cause harm or
injury.
WARNING
To avoid entrapment, make sure to keep the
residents hair, arms and feet close to the body and
use designated grab supports during any
movement.
