the toilet or bath. The hoist has a Safe Working Load (SWL) of 228kg (501 forlb):newrefereditionsto NOTE. .
NOTE: The SWL will depend on the hoist configuration (attachments) always refer to the maximum SWL label adhered to the lowest rated fitted attachment.
Each Maxi Move is supplied with two 24V rechargeable batteries and a charging unit.
Features of the hoist comprise:
•Emergency lowering button and limit stop switch.
•Emergency stop/reset switch with thermal cut-out.
•Overload current circuit breaker.
•Overload current limit protection in the PCB.
•Up limit switch.
•Down limit/slack tape switch.
•Additional mast keypad.
•Emergency manual wind down.
•Battery condition and machine hours run display.
•Audible low battery warning.
The raising and lowering mechanism comprises an electro mechanical linear actuator powered by 24V DC motor.
The leg opening and closing mechanism comprises a 24V DC motor and single-ended actuator
(legs open independently).
The Maxi Move with the ‘Lock & Load’ (combi attachment) has the facility to accommodate:
•A 2 point spreader bar for use with a loop sling to support patients with contracted (restricted movement) or ‘windswept’ (deformed) limbs and walking slings.
•A 2 point loop small.
•A 2 point loop medium.
•A 4 point loop large.
•A 4 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)).
•Patient Weighing Scale.
Alternatively the Maxi Move can be a dedicated lifter that is also available with a 200mm extended jib. If fitted with the extended jib this hoist then has a reduced SWL of 130kg (286 lb) with the following options:
•Dynamic Positioning System powered or non-powered (DPS).
•Patient Weighing Scale.

Risk Assessment Checklist for EngineersReference Copy
Printed
WARNING: IF IN DOUBT ASK DO NOT TAKE UNNECESSARY RISKS3:37. pm, Aug 22, 2006
Check occasionally
The following assessment MUST be made before carrying out servicing, repairfor newworkeditionsor . 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.
NOTE: The above wipes should be of the type that has proven bactericidal action for disinfecting hard surfaces against MRSA & E.COLI.
•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.
•DANGER – Electrical Shock can kill.
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.

Spacer of nylon together with new steel spacer for actuator attachment (noise reduction).
Stop screw securing nut on dedicated loop without DPS (Loctite should be applied as screw has no pre-applied locking) .See page 15.
Stop screw securing nut on dedicated DPS loop, Combi Jibs extended to 8 mm (safety reasons). See page 13 and 15.
New version of Jackplug (reinforced version)
Covers for scale jib with five screws instead of three screws ( to replace either cover on old versions will need both new top and bottom cover and two new screws).
The welding of the two steering pins on the detachable combi hanger bar has been reinforced.
Plastic spacer added for the micro switch mechanism on top of the inner mast in order to prevent the micro switches from “missing” the top mounting and not being activated.

Loctite Application
Reference Copy

3:37 pm, Aug 22, 2006
Check occasionally for new editions.
Refer to the manufacturer instructions on the container before use, in addition to the following information.
(a)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.
NOTE: Because Loctite 243 is oil tolerant it is not necessary to prepare to the same standard of oil free cleanliness as for Loctite 242.
-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.
NOTE: The cure time will depend on the materials used, the ambient temperature and the bond line gap.
-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.

12 Monthly Service Procedure
WARNING: OBEY ALL RELEVANT SAFETY PRECAUTIONS.
-Visually check the general condition of all external parts.
-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 replaces the previously used Technical Advice Notices (TAN) with status A
(Safety issue, requiring some form of recall) or B (Non safety issue).
The check 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.

-Check the serial number of the hoist this is located on the mast console behind the 24V battery: refer to bar-code label.
-Check that all labels are legible replace as necessary.
-Check that the operating controls on the handset function correctly. If necessary recommend replacement.
-Check that the operating controls on the keypad mounted on the console function correctly at all limits.
-Operate the emergency lowering switch, the hoist must lower.
-Push in the ‘STOP’ button. When pressed in, all power functions should be inoperative. Press the ‘ON’ button to reset.
-With the hoist jib positioned at approximately its mid lifting height:
-Using the handset, lower the hoist jib.
-Keeping the handset button depressed use your other hand to restrain the weight of the jib.
-The motor will stop while the jib remains restrained by your hand, release the button on the handset.
-Remove your restraint of the jib.
-The jib must remain in its previously restrained position.
-Repeat using the mast keypad.
NOTE: The lift actuator has a recommended number of 40,000 lift cycles or 440 hours of use before replacement. One lifting cycle equals raising then lowering the patient.
