Conditions of Performing Service/RepairLift and transfer of a person will always pose a certain risk and only certified personnel are allowed to repair and service the equipment and accessories covered by this technical manual.
Only certified personnel are allowed to open hoist or acces-sories to perform service or repair. Risk of injury from rotating parts and electric shock.
Activate emergency stop before opening side covers. Disconnect battery before any repair or service.
When disassembling and assem-bling the lifter, take care that no cables are squeezed or damaged, this might cause malfunction.

General
Product IdentificationThe Product labels barcode contain product ID, serial number and production date.
Transport and Operating Conditions
Transport and StorageFor long time storage it is recommended that the emergency stop button is activated (pulled out). The lifter can be stored and transported under temperatures between -25 - 70 C.
OperatingThe lifter is designed for use at standard room temperatures (+5 to +40C).Air Pressure: 70 - 106 kPaRelative Humidity: 15 - 93 %Following storage or transport at other tempera-tures leave the lifter in a room with a suitable temperature until it reaches a safe operating temperature.
Medical electrical equipment requires special precautions regard-ing electromagnetic compatibility (EMC). Portable or mobile radio communication equipment may affect the medical electrical equip-ment, and should be kept minimum 25 cm (10 inches) from the lifters electronics.
Battery and Service indicator
The lifter has two indicator lights.
Wrench symbol / Service lightBattery symbol / Battery light
The electrical system has a power save functionwhich will turn off the electrical system after tenminutes without activity. All lights will turn off.The system is activated when pushing one of theoperating buttons
Battery LightThe battery indicator light will illuminate and make a sound when battery level is low and the lifter requires charging. When this occurs the lifter will have sufficient power available for one full lift cycle with SWL. When battery is critically low it is only possible to lower the lifting band.
Service LightThe electronics record the loads lifted and how much the lift has been used. After a certain period of operation a signal is given to indicate that service is required.

Service Scope
Service scopeService involves replacing the lifting band and inspection/replacement of worn parts. This must be carried out by authorised personnel.
Service is needed when the service light is red (calculated 5.000 lifts in weightclass 2), or service is required after 5 years if the service counter not has displayed red yet.
Authorised service personnel can use the Molift Service Tool to take readings of the lifts data and number og lifts.

How to open
Disconnect battery
Emergency Stop
Activate emergency stop before opening side covers.
Pull to activate emergency stop. The button will come out, and hoist will stop.
Remove sidecovers
Push down and press cover outwards with a flat screwdriver in the two slots to open cover.
Disconnect battery before any repair or service.
1. Activate emergency stop.2. Open side cover.
3. Locate battery cable on PCB, and disconnect.
Be careful when removing contact. Make sure not to damage any of the PCB components when pulling out contact.
Example: The component behind contact has been damaged when removing battery contact.

Molift Service Tool
Authorised service personnel can use the Molift Service Tool software to take readings of the lifters data and to log servicing work. The owner of the lift is responsible for logging service work and repairs.
Connect Service Tool Cable
1. Remove hand control cover.
2. Unplug hand control and and insert service tool cable.
3. Refer to User Manual for Molift Service Tool for instructions on how to use the Molift Service Tool software.

Technical description
The motor for raising and lowering is of the 24 V DC (direct current) type fitted with a worm gear and 24V DC Brake.The trolley is directly connected to the gearhouse, and the gearhouse is loadbearing.
The lifter is programmed with a maximum current limit for lifting motor. It prevents the lifter from lifting more than SWL.
Sensors/Microswitches
End/Angle: Activated if band angle to steep, or band completely in.
Band Slack: Activated if band is not in contact with the guiding drum. This occurs if no weight is applied to lifting band, or band is completely out.
Drum size: The switch is activated by a trigger arm when more than half of the lifting band is out, approx. 150 cm/60 inches. When the micro switch is activated it reduces the maxi-mum current limit. The current limit prevents the lifter from lifting more than SWL. More band on the drum gives higher torque and the motor will require more current to lift max load when drum is full of band, and less current when drum is empty.
