Invacare® ReliantTM 450/600
2.2 Operating Information
2.2.1 General
WARNING! -The Invacare patient lift is NOT a transport device. It is intended to transfer an individual from one resting surface to another (such as a bed to a wheelchair). -DO NOT attempt any transfer without approval of the patient’s physician, nurse, or medical assistant. Thoroughly read the instructions in this user manual, observe a trained team of experts perform the lifting procedures, and then perform the entire lift procedure several times with proper supervision and a capable individual acting as a patient. -Use common sense in all lifts. Special care MUST BE taken with people with disabilities who cannot cooperate while being lifted. -Invacare slings and patient lift accessories are specifically designed to be used in conjunction with Invacare patient lifts. Slings and accessories designed by other manufacturers are not to be utilized as a component of the Invacare patient lift system. -If the patient lift is exposed to extreme temperature (above 100°F or below 32°F), high humidity, and/or becomes wet prior to use, ensure the handgrips do not twist on the patient lift handle; otherwise, damage or injury may occur.

9

1145810-E

2.2.2 Pinch Points and Positioning
WARNING! -Be aware of pinch points, such as between the boom and hanger bar and at the base of the lift, to prevent pinching fingers. -When positioning the lift, be aware of the position of the hanger bar and the patient. Injury could occur.

2 Safety

Fig. 2-1
2.2.3 Lift Assembly
WARNING! -DO NOT overtighten the mounting hardware. This will damage the mounting brackets.
2.2.4 Lift Operation
WARNING! -Although Invacare recommends that two assistants be used for all lifting preparation and transferring-from and transferring-to procedures, our equipment will permit proper operation by one assistant. The use of one assistant is based on the evaluation of the healthcare professional for each individual case. -Make sure there is an audible click when mounting the battery on the battery charger to confirm proper mounting; otherwise, injury or damage may occur. -DO NOT exceed the maximum weight limitation of the patient lift. The weight limitation for the RPL450-2 is 450 lb; the weight limitation for the RPL600-2 is 600 lb. -ALWAYS keep hands and fingers clear of moving parts to avoid injury.

1145810-E

Invacare® ReliantTM 450/600
2.2.5 Using the Sling
WARNING! -Use an Invacare-approved sling recommended by the individual’s doctor, nurse or medical assistant for the comfort and safety of the individual being lifted. -DO NOT use any kind of plastic-back incontinence pad or seating cushion between the patient and the sling material that may cause the patient to slide out of the sling during transfer. -After each laundering (in accordance with instructions on the sling), inspect the sling(s) for wear, tears, and loose stitching. -Bleached, torn, cut, frayed, or broken slings are unsafe and could result in injury. Discard them immediately. -DO NOT alter the slings. -Be sure to check the sling attachments each time the sling is removed and replaced to ensure it is properly attached before the patient is removed from a stationary object (bed, chair, or commode). -If the patient is in a wheelchair, secure the wheel locks in place to prevent the chair from moving forward or backward. -When connecting slings equipped with color-coded straps to the patient lift, the shortest of the straps MUST be at the back of the patient for support. Using the long section will leave little or no support for the patient’s back. The loops of the sling are color coded and can be used to place the patient in various positions. The colors make it easy to connect both sides of the sling equally. Make sure there is sufficient head support when lifting a patient.

2 Safety
2.2.6 Lifting the Patient
WARNING! -When using an adjustable-base lift, the legs MUST be in the maximum Opened/Locked position before lifting the patient. -When elevating a few inches off the surface of the stationary object (wheelchair, commode, or bed) and before moving the patient, check again to make sure the sling is properly connected to the hooks of the hanger bar. If any attachments are not properly in place, lower the patient back onto the stationary object (wheelchair, commode, or bed) and correct the attachments. -Adjustments for safety and comfort should be made before moving the patient. The patient’s arms should be inside of the straps. -Invacare slings are made specifically for use with Invacare patient lifts. For the safety of the patient, DO NOT intermix slings and patient lifts of different manufacturers. The warranty will be voided. -Check the sling attachments each time the sling is removed and replaced to ensure it is properly attached before the patient is removed from a stationary object (bed, chair or commode). -During transfer, with the patient suspended in a sling attached to the lift, DO NOT roll the caster base over uneven surfaces that could cause the patient lift to tip over. Use the steering handle on the mast at all times to push or pull the patient lift. -Invacare does not recommend locking the rear casters of the patient lift when lifting an individual. Doing so could cause the lift to tip and endanger the patient and assistants. Invacare does recommend leaving the rear casters unlocked during lifting procedures to allow the patient lift to stabilize itself when the patient is initially lifted from a chair, bed, or any stationary object.

2.2.7 Transferring the Patient
WARNING! To reduce the risk of injury or damage: -When elevated a few inches off the surface of the stationary object (wheelchair, commode, or bed) and before moving the patient, check again to make sure the sling is properly connected to the hooks of the hanger bar. If any attachments are not properly in place, lower the patient back onto the stationary object (wheelchair, commode, or bed) and correct the attachments. -Wheelchair wheel locks MUST be in a locked position before lowering the patient into the wheelchair for transport. -Before transferring, check that the wheelchair weight capacity can withstand the patient’s weight. -Be sure to check the sling attachments each time the sling is removed and replaced to ensure it is properly attached before the patient is removed from the bed or chair. -The mast pivot under the rubber boot must be tight to ensure safe use of the patient lift. The bolt must be checked at least every six months in conjunction with periodic maintenance.
2.2.8 Maintenance
WARNING! -Maintenance MUST be performed ONLY by qualified personnel. -The pump is sealed at the factory. DO NOT attempt to open the pump or obtain local service as this will VOID the warranty and might result in damage. Consult your dealer or contact Invacare for more information. -After the first year of use, the hooks of the hanger bar and the mounting brackets of the boom should be inspected every three months to determine the extent of wear. If these parts become worn, they must be replaced. -Casters and axle bolts must be inspected every six months to check for tightness and wear. After the first 12 months of operation, inspect the hanger bar and the eye of the boom to which it attaches for wear. If the metal is worn, the parts MUST be replaced. Repeat this inspection every six months thereafter. -Regular maintenance of patient lifts and accessories is necessary to assure proper operation. -DO NOT overtighten the mounting hardware. This will damage the mounting brackets. -After the first six months of operation, inspect all pivot points and fasteners for wear. If the metal is worn, the parts MUST be replaced. Repeat this inspection every six months.

Thoroughly read the instructions in this Owner’s Manual, observe a trained team of experts performing the lifting procedures, and then perform the entire lift procedure several times with proper supervision and a capable individual acting as a patient. -The legs of the lift must be in the maximum open position and the shifter handle locked in place for optimum stability and safety. If it is necessary to close the legs of the lift to maneuver the lift under a bed, close the legs of the lift only as long as it takes to position the lift over the patient and lift the patient off the surface of the bed. When the legs of the lift are no longer under the bed, return the legs of the lift to the maximum open position and immediately lock the shifter handle.
Although Invacare recommends that two assistants be used for all lifting preparation and transferring from and transferring to procedures, the equipment will permit proper operation by one assistant. The use of one assistant is based on the evaluation of the healthcare professional for each individual case.

11.3 Weighing the Patient
WARNING! -The weight capacity is limited to the lowest-rated capacity of any one of the components in use (for example, the Patient Lift, Sling or Scale). The patient’s weight MUST not exceed the lowest-rated capacity of any component. -DO NOT operate key strokes with pointed objects (for example, pencils, pens, or fingernails); otherwise, damage to the keypad will result.
1. Attach the sling straps to the hanger bar. For proper attachment instructions, refer to 7.1.2 Attaching Slings to the Lift, page 35. For improved accuracy on the 450 and 600 Reliant Lifts, attach all sling straps to the center hooks on both sides of the hanger bar. However, patient comfort may require a different configuration of the sling straps.
