Liko M220 / Liko M230 Instruction Guide

Product Description

The Liko M220 and M230 are user-friendly mobile lifts designed for nursing homes and home environments. They serve as excellent aids for daily transfers of adults and children, facilitating movement to and from wheelchairs, toilets, and floors.

The primary difference between the models lies in their base width adjustment mechanism: the Liko M230 features an electric base, while the Liko M220 has a manual base for opening and closing the legs. Both lifts are equipped with an electric lift mechanism.

The performance and safety of Liko lifts are significantly enhanced by the use of individually fitted slings and other accessories.

In this document, the person being lifted is referred to as the patient, and the person assisting is referred to as the caregiver.

▲ This symbol indicates a warning triangle used for situations requiring extra care and attention.

i IMPORTANT! Read the instruction guides for both the patient lift and lifting accessories before use. Lifting and transferring a person always involves a certain level of risk. It is crucial to fully understand the contents of these guides. The equipment should only be operated by trained personnel. Contact your Liko/Hill-Rom representative for any uncertainties or questions.

Safety Instructions

Before using, make sure that:

• The lift is assembled according to the assembly instructions.
• The lifting accessories are properly attached to the lift.
• The batteries are charged for at least 6 hours.
• You have read the instruction guides for the lift and lifting accessories.
• Personnel using the lift are informed of the correct operation and use.

Before lifting, always make sure that:

• The lifting accessories are not damaged.

Assembly

Steps for assembling the lift:

1. Place the base on the floor with wheels contacting the floor. Lock both rear wheels. Place the lift mast in the foot of the base.
2. Secure the lift mast using two M10x25 screws and the 6 mm Allen wrench provided. Ensure screws are tight.
3. Place the control box in the bracket on the lift mast. Lock the control box using the M5 screw and 3 mm Allen key provided. Do not overtighten.
4. Install handles at the lift mast: Attach with two M10x25 screws and the 6 mm Allen wrench. Insert the casing (M10) in the forward attachment of the handles, use two M10x16 screws and the two 6 mm Allen wrenches. Ensure all four screws are tight.
5. Place the quick reference guide (using the provided chain) and the hand control on the handles.
6. Connect cables to the control box. Ensure plugs are fully seated.
7. Connect the charger cable to the socket under the control box. Ensure the plug is fully seated. Attach the cable.
8. Connect the battery and secure it to the control box bracket. A click sound indicates correct installation.
9. Reset the emergency stop by turning the button in the direction of the arrows. Charge the battery (see "Charging the Batteries" section).

After assembly, ensure:

• The lift battery is charged.
• The lift arm motion corresponds to the buttons on the hand control.
• The manual and electrical emergency lowering functions work.
• The base width adjustment is functional.
• The rear wheels brakes are functional.

Operation

Emergency Stop: Use in urgent need to stop all lift functions. Activate by pressing the red button on the control box. Reset by turning the button in the direction of the arrows until it springs out.

Manual Emergency Lowering: Turn the red cylinder in the direction of the arrows.

Electrical Emergency Lowering: Push a narrow object into the hole marked "Emergency" on the control box. ▲ The object used must not be sharp, as it may damage the control box.

Hand control: The lift motion is operated by push buttons on the hand control. Arrows indicate direction. Press ⬆ to raise or ⬇ to lower the lift arm. The motion stops when the button is released. For electrical base width adjustment (Liko M230), push ⏶ or ⏷.

Manual Adjustment of the Base (Liko M220): Press the raised pedal to adjust the base width.

Lifting Procedures

▲ Never move the lift by pulling on the actuator!

Wheels with brakes: During lifting, wheels should be unlocked to allow the lift to center around the patient's center of gravity. The rear wheels can be locked against rotation and turning by pressing the lock pedal down. Release the brake by lifting the lock pedal with your foot.

Installation of Latches: After installation, ensure the spring-loaded latches are taut against the sling bar and move freely in the sling bar hook.

Lift correctly!

Before each lift, make sure that:

• The sling loops at opposite sides of the sling are at the same height.
• All sling loops are fastened securely into the sling bar hooks.
• The sling bar is level during the lift (see Figure 1).

If the sling bar is not level (see Figure 2), lower the user to a firm surface and adjust according to the Sling in use Instruction Guide. ▲ An improper lift can be uncomfortable for the user and cause damage to the lift equipment!

Position of the Lift when Lifting:

• From/To: Bed
• From/To: Chair/Toilet Seat
• From/To: Floor: NOTE: Place a pillow under the patient's head for increased performance and comfort. Always have the wheels locked when lifting from the floor.

Charging the Batteries

Indications for Charging the Battery: A signal from the control box will sound in the event of low battery voltage. This occurs only when a hand control button is pressed. Charge the battery as soon as possible. There is still sufficient power for additional lifts.

Battery Charging and Maintenance:

• Charge the battery regularly for maximum battery life. Recommend charging after each use or every night. Batteries are fully charged after approximately 6 hours. The charger switches off automatically when fully charged.
• If the lift is not used daily, connect it to the charger or press the emergency stop after use to turn off power and save the battery. Ensure the battery is fully charged before pressing the emergency stop.
• NOTE: The lift cannot be charged with the emergency stop engaged.
• NOTE: During charging, a yellow indicator light on the control box illuminates. This light turns off when the battery is fully charged. If the light does not turn off after 8 hours, the battery may need replacement. Stop charging and replace the battery.
• ▲ Never charge batteries in a wet area.

Alternative Charging Procedures:

• Built-in Charger (standard): Connect the charger cable to an electrical outlet (100-240 V AC). Ensure both lights on the control box are lit. Yellow light indicates charging; green light indicates power supply to the charger. Replace the cable if it shows signs of stretching to minimize risk of catching and breaking. NOTE: The lift cannot be used while the charger cable is plugged in.
• Wall-Mounted Charger or Table Charger (accessory): Remove the battery from the control box by releasing the locking device.
• Alt. A (accessory): Place the battery on the wall-mounted charger. Plug into an electrical outlet (100-240 V AC). Ensure both charger lights are lit (yellow for charging, green for power supply).
• Alt. B (accessory): Place the battery on the charger in the table charger housing. Plug into an electrical outlet (100-240 V AC). Ensure both charger lights are lit (yellow for charging, green for power supply).

Liko M220 and M230 comply with Directive 2002/96/EC on waste electrical and electronic equipment. Dispose of old batteries at the nearest recycling facility or authorized personnel.

Maximum Load

Maximum loads can vary based on the assembled lift unit, including the lift, sling bar, sling, and accessories. The overall maximum load is determined by the component with the lowest maximum load rating.

▲ Using lifting accessories other than those approved can entail a risk.

When changing lifting accessories, the highest possible lifting height of the lift is affected. Ensure that the lift can still fulfill the desired lifting height after the change.

For Liko M220 and Liko M230, all slings compatible with Universal SlingBar 450 are recommended. Refer to the brochure "Lifting accessories" for selecting suitable slings and other accessories. Consult the respective sling model instruction guides for guidance on combining Liko's sling bars with Liko's slings.
