Make sure end stops are mounted in all ends of the Rail system before using the hoist!

Lifter installation

Be carefull during elevated work situations. We recomend two or more installers, to prevent loosing balance and injury during installation!

Mounting of Lifter on trolley. No tools required. The lifter has two connection points.

Connect one point first. Push button all the way in, and place lifter in connection point on trolley. Release button and make sure it is clearly showing green before connecting the next point.

Make sure both connection point buttons completely return and clearly show green after installation.
Emergency lowering cord and tube can be adjusted to the correct length (height) by cutting tube and cord.

Use this checklist to verify that the hoist is properly installed and can operate correctly and safely before use.

• End stops on rail are installed after mounting of trolley as described in BM4401
• Make sure that the hoist is properly fastened to the rail and that the lift does not have any loose parts.
• Perform one lift with load (60-80 kg)
• Make sure battery is fully charged.

How to use Molift Air

General Safety Precautions

Only use accessories and slings that are adjusted to fit the client, type of disability, size, weight and type of transfer.

Working pause ratio/Duty Cycle.

Molift Air 500 should not be run constantly for more than 2 minutes (with maximum load), and rest for minimum 18 minutes. Duty Cycle 10%. (Intermittence according to standard ISO-EN 10535)

Do not position hoist in a way that makes it difficult to disconnect mains cable. To isolate the system, pull out the main cable from the elektrical wall socket.

If maximum load (SWL) differs between hoist sling bar and body support unit, then the lowest maximum load shall always be used

Molift lifters shall only be used to lift clients. Never use the lifter to lift or move objects of any kind.

Before use / Daily check

Inspection to be performed by caregiver daily or before use:

• Inspect lifter and rail system has no visible damage, defects or deformations
• Make sure sling bar connection and all detachable parts are properly connected and secured
• Test emergency stop button and emergency lowering
• Make sure battery indicator or service light is not illuminated
• Make sure lifting strap does not have visible damage or frays.
• Test run lifters operation functions and make sure lifter does not make any abnormal sounds

If there are any faults or defects, the lift needs to be taken out of operation and marked ”out of order”. No parts on the Molift Air should be serviced or maintained while in use with a patient.

Hand control

The Hand control has 2 buttons for lifting and lowering, or 4 buttons if the hoist is equipped with propulsion. The Hand control has an indicator light that will illuminate when battery level is low and the lifter requires charging

Do not pull Hand control to move the hoist along the rail

The lift will not work if hand control is connected to a charger. Disconnect hand control from charger before operating the lift.

Mounting sling bar

1. Align sling bar in connection point.
2. Push button on locking pin and insert all the way through.
3. Make sure locking pin is properly fastened
4. Push and hold down the button on the locking pin, and pull to remove locking pin.

Emergency stop / emergency lowering

Emergency Stop
Activation and reset of emergency stop:

Pull to activate emergency stop. The button will come out, and hoist will stop.
Push with finger or use tube on cord to push button back in to reset emergency stop.

Electrical Emergency Lowering

Pull and hold to start lowering. Hold until client is lowered and can be released from sling bar.

Only for emergency use when hand control does not work!

Manual Emergency lowering

Allen key or bit for power drill can be found inside the lifter. Remove covers on both sides of the hoist to locate.

To open side covers use a screwdriver or power drill on all 8 screws (4 on each side). Turn the red “Brake Release” handle up. Locate the tools on the other side of the hoist and rotate counterclockwise to lower lifting belt. Using a power drill is recommended.

Service is NOT required if:

1. the Air manual emergency down is used for a known reason, and
2. the belt is undamaged, and
3. the unit is operating normally after the manual emergency lowering procedure.

The new brake override will contribute to this by making emergency manual lowering less stressful to lift components.
If the unit have had a malfunction with unknown reason, and manual emergency lowering system has been used, Service is required.

Electronics

Transport and Storage

For 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.

Operating

The lifter is designed for use at standard room temperatures (+5 to +40°C).
Air Pressure: 70 – 106 kPa
Relative Humidity: 15 – 90 %
Following storage or transport at other temperatures leave the lifter in a room with a suitable temperature until it reaches a safe operating temperature.

 Medical electrical equipment requires special precautions regarding electromagnetic compatibility (EMC). Portable or mobile radio communication equipment may affect the medical electrical equipment, and should be kept minimum 25 cm (10 inches) from the lifters electronics.

The electrical system has a power-save function which will turn off the electrical system five minutes after last operation. All indicators will turn off.The system is activated when pushing one of the operating buttons on the hand control.

Battery indicator on hoist

When the multi level battery indicator is yellow the lifter will have sufficient power available for at least one full lifting cycle with max load. When battery is flashing yellow it is only possible to lower the sling bar.

Service indicator / Periodic inspection

The lifters electronics record the weight lifted and number of lifts. After a certain period of operation a signal is given to indicate that service is required.

Service scope

Service involves replacing the lifting belt and inspection/ replacement of worn parts. This must be carried out by authorized personnel. Service is needed when the service light is red (calculated 5.000 lifts in weight class 2). Contact Etac your local dealer, or see etac.com for a recommendation of an approved service partner.

Charging

Molift Air 500 can be charged through the hand control with a battery charger, or through the rail with In Rail Charging.

Transfer

Plan the lifting operation in advance to ensure that it is as safe and smooth as possible. Remember to work ergonomically. Assess the risks and take notes. The assistant is responsible for the safety of the user.

Molift Air can be used with both 2-point and 4-point sling bar for different types of transfers; sitting, recumbent or ambulating.

Using slings

It is important that the sling has been tested with the individual user and for the intended lifting situation.

Read User Manual for the sling prior to use.

 Do not to use damaged or badly worn slings.

Slings made by other manufacturers

We recommend only using Molift slings. Etac shall not be liable for faults or accidents that can occur when using slings made by other manufacturers.

Lifting and lowering

When moving the client, stand to the side of the client you are lifting. Make sure that arms and legs do not obstruct the seat, bed, etc. Keep eye contact with the client to help them feel safe.

The 4-point sling bar must always be positioned across the client, to prevent the client from unintentionally sliding out of the sling.

The sling bar hook design prevents sling to be inadvertently detached when mounted correct.

1. Check that the sling is correctly fitted around the client and that the strap loops are correctly fitted to the sling bar hooks.
2. Stretch the sling straps without lifting the client. Ensure that all four loops of the sling are securely fastened to avoid the user slipping or falling.
3. Lift client, and perform transfer.

Angle sensor

The hoist has a directional safety feature that prevents lifting if angle on lifting strap is to steep.

If the hoist doesn’t respond to Hand control “up” button, it might be because lifting strap angle is to steep, or lifting belt is twisted and sensor is activated.
