Locking the Wheels The rear wheels can be locked to prevent rotating and turning. The locking/unlocking of the wheels is done with the foot. Locked wheels during lifting can increase the risk of tipping. NOTE: When lifting, the wheels should be unlocked so that the lift can be moved to the patient’s centre of gravity. The wheels should be locked, however, if there is a risk of the lift rolling into the patient, for instance, when lifting from the floor.

Emergency stop Activate: Press the red button on the control box. Reset: Turn the button in the direction indicated by the arrows on the button.

Mechanical Emergency Lowering Emergency lower by moving the handle marked “Emergency lowering” up and down. Repeat the motion until the patient being lifted is on a firm surface; draw down the sling bar manually and continue to pump the handle until the sling bar is low enough to enable the sling’s strap loops to be unhooked.

Electrical Emergency Lowering/Raising Use the arrow buttons on the operation panel (up or down) until the patient being lifted is on a firm surface and the strap loops of the sling can be unhooked.

a

Adjustment of the lift interval level If it is necessary to reach a lower level with the sling bar, this can be arranged by lengthening the lift strap using the mechanical emergency lowering device. Do not lengthen the strap more than necessary as the highest obtainable lifting level is also affected. An example of when it would be advantageous to lower the lift interval is when lifting from the floor using a sling whose strap loops do not reach up to the sling bar hooks when the lift is in its lowest position. Do as follows: Push down the red emergency lowering handle at the same time as loading the sling bar (pull down the sling bar with your other hand). This extends the strap and the sling bar is lowered. Repeat until the required strap length is obtained.

After mechanical emergency lowering / Restoring the lifting level If the lift strap has been lengthened due to using the emergency lowing function, the lift interval height will be lower than previously. To restore maximum lifting height, the lift strap must be reset to its original length. Do as follows: 1. Remove any load / weight from the strap above the emergency lowering device. Do this by either placing the sling bar above the lift arm or by another person holding the sling bar up so that the strap hangs loose. 2. Lower and raise the handle marked “Emergency lowering” with your left hand. At the same time tension the strap by turning the black knob (a) clockwise with your right hand. Repeat this procedure until the red mark on the strap is just above the emergency lowering device.

Armrest To use the armrest you need to rotate it from the (vertical) rest position up to the (horizontal) support position. The armrest have two purposes: to help the patient feel more secure and facilitate for the caregiver when moving the lift. When using the lift to transfer a patient between rooms, the armrest should be set in the support position! Golvo • 7EN140107-01

WRONG!

WRONG!

Parking the sling bar When the lift is not in use or is being moved without a load, it can be beneficial to place the sling bar in the parking panel.

Avoid uneven lifting Always ensure that the lift strap is vertical and parallel to the mast when lifting. To achieve this, think of Golvo’s position under the bed. Adjust the width and/or place Golvo differently under the bed to achieve the correct position. Do not lift when the load is unbalanced on the lift strap as this can cause instability as well as wear the strap. Unbalanced lifting poses a tipping risk!

The parking panel is intended for parking Universal SlingBars 350, 450 and 600 (all models). When the sling bar is parked in the parking panel, the lift should not be raised since this could be dangerous and cause personnel injury or damage to the lift if the sling bar should release and swing out from the panel.

Charging the Batteries 2 3 4

1

Battery Capacity Check the battery capacity by pressing the i-button (1). The following information can be read: 2 - Green light: More than 50% of the battery capacity remains. 3 - Orange light: 25–50% of the battery capacity remains. 4 - Orange light: 0–25% of the battery capacity remains. The indication lamps light up for about half a minute; they then go out. The battery capacity is also shown when the lift is in use.

To obtain maximum service life, it is important to charge the batteries regularly. We recommend charging after use of the lift or every night. Maximum charge is obtained after about 5 hours. When the batteries are fully charged, the charger switches to “trickle charging” automatically. During charging the lights shine alternatively (orange, orange, green). For deeply discharged batteries, the indication for initiated charging can be delayed a few minutes. Completed charging is indicated by a flashing green light. When the operation time is noticeably shortened, the batteries probably need changing. Stop charging and switch batteries. The lift cannot be charged with the emergency stop engaged. Never charge batteries in a wet area. NOTE! If the lift is not to be used for a long period, the battery should be connected to charging.

Charging With built-in charger: Check that the charger cable is connected to the control box outlet; see p. 6. Connect the charger cable to an electrical outlet (100-240 V AC). Completed charging is indicated by a flashing green light on the battery. If the charger cable is permanently stretched, it should be replaced in order to minimize the risk of the cable getting stuck and breaking. NOTE! The lift cannot be used when the charger cable is plugged into a wall socket. Old batteries are to be deposited at the nearest recycling station or given to personnel authorized by Liko/Hill-Rom.

Maximum Load

Different maximum loads may apply to different products on the assembled lift unit, sling bar, sling and any other accessories used. For the assembled lift unit, including accessories, the maximum load is always the lowest maximum load rating for any of the components. A Golvo that is approved for 200 kg (440 lbs) can be equipped with a lifting accessory that is approved for 300 kg (660 lbs). In this case, the maximum load of 200 kg (440 lbs.) applies to the assembled lift unit. Study the markings on the lift and lifting accessories or contact your Liko/Hill-Rom representative if you have any questions.

Recommended Lifting Accessories Using lifting accessories other than those approved can entail a risk. Generally recommended sling bars and accessories for Golvo mobile lifts are described below. When changing a sling bar or other lifting accessories, the highest possible lifting height of the lift is affected. Before changing lifting accessories you should always ensure that the lift, after change, can fulfil the desired lifting height in order to manage the lifting situations for which the lift is to be used. To select suitable slings and other lifting accessories, please see the “Golvo” and “Lifting accessories” brochures. For additional guidance in selecting a sling, study the operating instructions for the respective sling models. There you will also find guidance for combining Liko’s sling bars with Liko’s slings.
