Check parts
Congratulations on purchasing your
Mygo Max System. All of the parts will be
contained in polythene bags with each one
clearly labelled. Carefully remove them from
the boxes and check all the parts you have
ordered.
Keep polythene bags away from
children.
Some of the accessories will need to be
assembled before you attach the seat to the
base you have purchased.
Multi-tool
A number of adjustments will require the use
of the multi-tool, which is supplied with each
seat and can be found in the back pocket of
the seat.
Open up the angle of the leg supports by
unscrewing the knobs (A), shown, and set to
the maximum width. Open the socket caps
(B) and slide in the calf supports. Set to the
desired position, with the footplates facing
forward and retighten the socket cap bolts
with the multi-tool.
Always make sure the foot plate is
attached firmly.
7.1 Setting the
footrests
Adjust the height of the chassis to its
maximum to reduce risk of back strain while
attaching the seat unit. Refer to Section 11
on how to adjust the height of the chassis
you have purchased.
First release the safety locking pin at the
front of the seat. To do this pull the pin out
and rotate through 90 degrees. Carefully lift
the seat and place it into the chassis. At the
rear of the underside of the seat you will see
a receiving channel. Place this securely over
the tube towards the back of the chassis.

Before transferring the child into the seat
carry out the daily product inspection as
outlined in section 13 of this user manual.
Adjust the seat to a comfortable height
to facilitate transfer. Lock all the castors,
ensuring that they are facing outwards
to maximise product stability. Make sure
the safety buckle on the chest harness is
released and is out of the way to facilitate
transfer.
If the seat has flip-away thoracic laterals,
first move these out of the way using knob
a. Unclip the Leeway Pelvic Cradle in the
middle, undo the side velcro of the Leeway
Pelvic Cradle and allow the harness to open
out to facilitate transfer. Lastly if sandals are
fitted open the straps. You are now ready to
transfer or hoist the child into the seat. The
Leeway Pelvic Cradle is fastened using the
middle buckle, and side velcro.
Always secure the Leeway Pelvic Cradle
first before fastening other buckles or
harnesses. Adjust the harness so the child
cannot slide or creep forward in the seat.
The correct positioning and tensioning
of the Leeway Pelvic Cradle is key to a
child’s postural management, affecting their
comfort and ability to carry out activities.
Please consult with your therapist to ensure
the Leeway Pelvic Cradle is positioned
correctly and that the straps are tensioned
appropriately.
10.1 Transferring your
child into and out of the
seat
10.2 Adjusting the
Leeway Pelvic Cradle
The Mygo Max is designed to fit onto a
range of chassis. This user manual shows
the correct and safe use of the seating
system with the Leckey Hi-low chassis. For
all other chassis or bases please refer to the
manufacturer’s handbook.
To prepare the Hi-low chassis for the seating
system we recommend that you raise the
chassis to a comfortable working height
by pressing the foot lever at the rear of the
chassis or by pressing the up button on the
handset of the powered option.
To tension the Leeway Pelvic Cradle use the
4 side straps (c) and the velcro tabs (d).
If using the seat outdoors and your child is
wearing a coat, position the Leeway Pelvic
Cradle under the coat.
10.3 Chassis

The powered chassis can be easily adjusted
with the push button control handset. The
seat can be height adjusted with the client
in the chair. When one of the buttons on
the handset is pressed, then the seat will
move up or down in that direction until the
button is released again, or if the actuator
has reached the end of its stroke.The system
is started by inserting the battery into the
circular holder in the end of the control
box. Clean the magnetic poles for all dirt
or metal chips before inserting. The battery
will magnetically hold itself in place with the
correct position , and a confirming long beep
is heard.
The control box checks the battery level
every 24 seconds, and when the battery
reaches a low limit, then the control box will
give a double-beep every 24 seconds to
indicate that the battery needs recharging.
This is done in the ”C3-charger”, full
re-charging takes 5-8 hours, depending
on state of charge. To remove the battery,
turn it 90 degrees (right- or left) to release it
from the magnets . The battery (NiMH-type)
can be recharged from any state of charge
without reducing battery life or battery-
capacity.
When connecting the ”C3-charger” to the
mains (100 – 240 V AC), the red diode lights
up continuously and a single flash in the
green diode appear before it turns off again.
When inserting the battery into the charger,
the green diode starts flashing with an
interval of 1/sec during the charging process.
When charging is finishing, the green diode
stops flashing and turns on continuously, the
battery is fully charged, can be removed and
is ready for use in the C3 controller.
10.4 Powered height
adjustment
10.5 Charging the
battery
Repeated runs at a high rate with heavy
loads, may create overheating inside the
battery – a safety interlock-temperature
sensor will disconnect the power. When
the battery has cooled down to accepted
working temperature the power switch on
automatically.
To secure long lifetime of NiMH batteries, it
is recommended to recharge the battery at
least every 3 months.
Beep signals:
Long beep: Power on (battery inserted)
Two short beeps: Every 24 seconds (when
the system is not in use): = indicating low
battery level, please recharge.
Two short beeps: When starting the actuator
= low voltage, please change battery soon,
or recharge—the battery will still give power,
but only limited time.
Long beep: When running the actuator =
battery lower than 17,6Volt (only down/in
movement will be accepted thereafter)
Continuous short beeps: (Temperature inside
control box too high, please take a break)
You can carry out this adjustment with the
child in the chair. To adjust the height of the
Hi-low chassis press the foot lever at the rear
of the chassis or press the up button on the
handset of the powered option whilst holding
the push handle. Once you remove your
foot from the pedal or your thumb from the
handset the seat will be fixed at the chosen
height.
For safety the height adjustment pedal on
the chassis can be locked by engaging the
pull pin (C) on the right hand side of the
pedal. To unlock pull the pin out and rotate
90 degrees, the pedal can then be operated.
The locking pin (C) should be kept in the
locked position when you are not adjusting
the chassis.
