INTRODUCTION
This document covers the maintenance and repair of the Maxi Sky 2 and Maxi Sky 2 Plus.
Maxi Sky 2 has a maximum capacity of:
- 272 kg (600 lb).
The Maxi Sky 2 Plus has a maximum capacity of:
- 454 kg (1000 lb) when set in dual mode.
- 272 kg (600) when set in single mode.
FEATURES
THE SAFE WORKING LOAD (SWL) WILL DEPEND ON THE LIFT’S
CONFIGURATION MAXIMUM SWL REFERS TO THAT OF THE LOWEST RATED
ATTACHMENTS, AS WELL AS RAIL INSTALLATION
NOTE
The emergency features of the Maxi Sky 2 ceiling lift include:
- Stop.
- Overload current limit protection in the PCB.
- Upper limit switch.
- Lower limit switch/no tension limit.
- Control panel on the unit / LED display
- Manual emergency lowering mechanism.
- Audible variable low-battery warning.
- Malfunction & maintenance code.
These tests will be performed after replacement of a part or a repair is performed to ensure the quality of the repair. The
test will be called out throughout section 6.
To perform a Full Featur Test on the MS2 Plus, refer to Maxi Sky 2 Plus document “Initial Start Up” 001-31229-EN section
14 “Testing the Maxi Sky 2 Plus System”.

DISPLAY SYMBOLS
The following is a description of all the symbols that may be presented on the display.
Battery Charge Level
• Several symbols showing a battery at a different charge levels. These symbols indicate the status of
the batteries and/or the regular charging system.
ECS Indicator
• On units equipped with ECS option, this symbol shows up when the batteries are charging, conrming
that the ECS system is operational.
RTC (Return to Charge)
• This symbol indicates that the RTC function was activated by the hand control.
RTH (Return to Home)
• This symbol indicates that the RTH function was activated by the hand control.
PPP (Pre-Programmed Position)
• This symbol indicates that the PPP function was activated by the hand control
Over Duty Cycle
• This symbol ashes when the lift is used for a long period without allowing it to cool down. This security
feature disables the function (Up, Sit/Reclined or Left/Right) that is being used beyond recommended
duty cycle to prevent damage.
• When the overheat protection is engaged, the function, which exceeded the duty cycle, is disabled
while all other functions remain active.
• The red light will stay on during a cooling period. In addition, a single beep will be heard.
General Malfunction (Warning symbol accompanied with a numeric character)
• This symbol ashes when the lift encounters a malfunction.
• The lift needs to be inspected / repaired by a qualied service technician.
• The red light will stay on and a single beep will be heard.
Maintenance Required (Wrench symbol accompanied with a letter character)
• This symbol is shown for 7 seconds (accompanied with 2 beeps) when the lift is waking up from sleep
mode and ashes every 5 seconds to draw the user’s attention.
Overweight
• This symbol ashes when a transfer is attempted with a load exceeding the lift’s capacity.
• The red light will stay on (accompanied with four rapid beeps) until the patient is lowered.
• The function is disabled while all other functions remain active.

MONITORING
Total lifts made since the initial start up.
Note : A lift is determined as one raising, waiting time for the transfer and one lowering.
Number of lifts made during the last day.
Note: A day begins at midnight (12 am).
Number of lifts made during the last week.
Note: A week begins on Sunday.
Average of lifts per day based on the last 7 days.
Hours of use since the initial start-up.
Number of times the safe working load was exceeded.
Number of times the duty cycle was exceeded.

Regular Charging System
2-function model: Move the lift under the charging station.
4-function model: Press the and buttons or the button to bring the lift to the charging station.
BATTERY INFORMATION
The batteries for this device are rechargeable lead acid batteries.
For safe handling and to extend the battery lifetime, please follow
and remember these instructions. Not following these instructions
can cause short battery life and may, in extreme cases, put user at
risk.
Battery life depends on many factors. These are: frequency of use,
frequency of charging, temperature of operation, storage and stor-
age time.
Using lead-acid batteries below 5% charge can damage the battery
resulting in shorter battery life. The 5% charge is indicated by the
critical battery level symbol ashing on the display. At this time, the
lift will allow only the down function. Make sure to recharge the bat-
teries as soon as possible.

This graph illustrates the relationship between
the number of lifts that can be performed before
reaching battery critical level, versus the load
being lifted.
For information about MS2 Plus battery autonomy,
refer to MS2 Plus IFU 001-31228-EN “Battery
Information” section.
DO NOT OPERATE THE CHARGING STATION WITH A DAMAGED CORD OR IF THE STATION HAS BEEN
DROPPED OR DAMAGED. DO NOT BEND THE POWER CORD BY FORCE, OR PLACE A HEAVY OBJECT ON IT,
SINCE IT COULD DAMAGE THE CORD AND MAY CAUSE FIRE OR ELECTRICAL SHOCK.
WARNING
THE LIFT CAN BE OPERATED AT ANY TIME DURING THE BATTERIES’ CHARGING, WHICH WILL STOP AUTO-
MATICALLY.

Check the LED to conrm that the batteries are charging properly.
• The LED will ash green until batteries are fully charged.
• The display will cycle through charge level icons according
to actual battery charge level to show the charging progress.
If the batteries have been completely drained it could take up to 8 hours
to completely recharge them.
