Safety Instructions
General
A. ARJO strongly advise that only ARJO designated parts, which are designed for the purpose,
should be used on equipment and other ARJO supplied appliances to avoid injuries attributable
to the use of inadequate parts. ARJO’s conditions of sale make specific provision confirming
no liability in such circumstances. Our policy is one of continuous development, and we
therefore reserve the right to change specifications without notice.
B. Unauthorized modifications on any ARJO equipment may affect its safety and are in breach
of any warranty on it. ARJO will not be held responsible for any accidents, incidents or lack of
performance that occur as a result of unauthorized modifications to its products.
C. If the terms listed below are used in the text their meaning is as follows:
D. Dangerous substances. If using hazardous substances be sure how to handle these and refer
to applicable information. In doubt refer to the local authorities for health and safety
requirements.
DANGER
Means: Electrical hazard warning, failure to understand and obey may result in electrical
shock.
WARNING
Means: Failure to understand and obey may result in injury to you or to others.
CAUTION
Means: Failure to follow these instructions may cause damage to all or parts of the system or
equipment.
NOTE
Means: This is important for the correct use of this system or equipment.

Introduction
The Maxi Move is a mobile patient lifter and is used for transferring patients from bed or chair
to the toilet or bath. The floor lift has a maximum safe working load (SWL) of 227 kg (500 lb).
Each Maxi Move is supplied with two 24V rechargeable batteries and a charging unit.
Features
The features of the Maxi Move floor lift include:
• Immediate stop/reset switch
• Overload circuit
• Overload current limit protection in the PCB
• Upper limit switch
• Lower limit switch/anti-crush
• Control panel on the unit
• Emergency manual wind down
• Handset LCD display
• Audible low-battery warning
The raising and lowering mechanism comprises an electromechanical linear actuator powered
by a 24VDC motor.
The leg opening and closing mechanism comprises a 24VDC motor and a double-ended
actuator (legs open independently).
Combi Feature
The Maxi Move with the ‘Lock & Load’ (combi attachment) has the facility to accommodate:
• A two-point spreader bar for use with a loop sling to support patients with contracted
(restricted movement) or ‘windswept’ (deformed) limbs and walking slings.
• A two-point loop small.
• A two-point loop medium.
• A four-point loop large.
• A four-point spreader bar Dynamic Positioning System (DPS) for general lifting (small,
medium and large).
• A 4 point powered spreader bar Dynamic Positioning System (DPS) for general lifting
(medium and large).
• A stretcher system for handling dependent, fragile patients with a minimum of
disturbance (SWL 160kg (350 lb)).
NOTE: The SWL will depend on the lift’s configuration and attachments. Always refer
to the maximum SWL of the lowest rated attachment.

Risk Assessment Checklist for Engineers
The following assessment MUST be made before carrying out servicing, repair work or
installations:
• Make sure the work area is adequately sized, suitably lit and at a reasonable temperature.
• The floor surfaces must be free from clutter, unevenness and non-slip.
• Use good engineering and manual handling practices to keep risk of injury at its lowest
level.
• Tools and equipment must be kept in good condition.
• Wear protective clothing and eye protection where necessary.
• You should be adequately trained to perform the task.
• Do not manually lift items that could cause personal injury, that is too heavy, hot or
sharp.
• You must comply with all local site safety rules, report any incident or accident to the site
safety supervisor or equivalent. Use the ARJO reporting procedure.
• If necessary use Hard Surface Wipes (Alcohol Impregnated) to decontaminate a machine
before carrying out any work.
• Load tests must only be applied as instructed in the relevant procedure.
• If it is necessary to work from a platform (i.e. scaffold, ladders etc.) to perform a service
or installation task make sure the platform is secure and suitable for the task.
• Do not perform maintenance tasks on equipment with ‘live’ electrical connections unless
absolutely necessary.
• Isolate the power supply before removing plugs, sockets or disconnecting cables.
• Be alert at all times to the dangers of working on electrical equipment that operates on
mains supply voltage. Where possible, visually inspect electrical cables and plugs etc. for
damage or deterioration before working on equipment.
• Dispose of all waste in appropriate containers.
WARNING: IF IN DOUBT, CONTACT YOUR LOCAL ARJO REPRESENTATIVE. DO
NOT TAKE UNNECESSARY RISKS.
NOTE: The above wipes should be of the type that has proven bactericidal action for
disinfecting hard surfaces against MRSA & E.COLI.
DANGER – Electrical Shock can kill.

Product and Technical Description
Loctite Application
Refer to the manufacturer instructions on the container before use, in addition to the following
information:
Procedure for the correct use of Loctite 242 and Loctite 243 (Colour blue) Threadlocking:
- Clean both of the joint faces with Loctite 7063 Cleaner or a lint-free cloth
moistened with Acetone or another suitable volatile solvent.
- Apply Loctite 243 sparingly but sufficient to fill all engaged threads. (This
product performs best in thin bond gaps [0.05 mm]).
- Install the threaded components and where known, torque to the applicable
torque figure. If the torque figure is not known tighten to a firm fixing.
- Clean off any unwanted adhesive.
- Allow the Loctite 243 to cure before subjecting to load.
- Where the cure speed is unacceptably long, or large gaps are present,
applying Loctite Activator ‘N’ or ‘T’ to the surface will improve the cure
speed.
For general Loctite specifications and application details: refer to Loctite manufactures
instructions.
NOTE: Because Loctite 243 is oil-tolerant, it is not necessary to meet the same
standard of oil-free cleanliness as for Loctite 242.
NOTE: The cure time will depend on the materials used, the ambient temperature
and the bond line gap.

10
Product and Technical Description
Torque Data and Consumable Materials
Thread retaining: Apply Loctite 243 when no threadlocking patch has been pre-applied. When
replacing a part with pre-applied threadlocking, the part should be replaced by a new part using
pre-applied threadlocking.

Service Procedures
Service Procedure 1
Check that the latest updates have been implemented
• Check if there are any field correction bulletins, safety notices or technical bulletins that
have been published since the last service. (These replace the previously used Technical
Advice Notices (TAN) with status A (i.e. safety issue, requiring some form of recall) or
B (non-safety issue).
• This verification must be done to keep the product up to date according to safety and
product improvements. Bulletins and notices can be generated as a result of an
engineering change note, a safety incident report or a change to form/fit etc.

Service Procedures
Service Procedure 2
Check the battery
The battery power tester will load the battery with a high current (up to 60 A, depending on
battery condition) for a short time and this will show the battery condition on a meter.
Battery test
1) The battery to be tested must be charged for at least 12 hours before test.
2) Connect the tester to the battery. DO NOT operate the test switch! When the tester is
connected, switch the test switch right or left for 1-2 seconds and take a quick reading on the
meter.
3) The meter will show the battery’s condition.
4) If the battery is OK, place the tested battery back in the charger.
Fig.5
WARNING!
• The battery power tester will become hot and there is a potential risk of fire.
• Make sure the battery power tester is kept away from inflammable material during
tests and for several minutes following the test.
• Beware of touching the metal casing for several minutes following the test.

Service Procedures
Check the battery charger
700.24250
1) Connect the cable from the test rig to the charger.
• Measure the voltage in the banana plug outlet of the rig. The voltage should be between
27.6 and 28 VDC.
2) Measure the current in the banana plug outlet of the rig.
• Turn the knob until the amber led indicator starts blinking.
• The current should now be between 0.9 and 1.1A.
