Operating Information

General

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). Otherwise injury or damage may occur.
DO NOT attempt any transfer without approval of the patient's physician, nurse or medical assistant. Thoroughly read the instructions in this Owner's 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 Invacare's 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 handgrips do not twist on patient lift handle - otherwise damage or injury may occur.

Pinch Points and Positioning

Pinch points exist between boom and hanger bar. Pinch points also exist at base of lift. When positioning lift, be aware of the position of the hanger bar and the patient.
Injury could occur.

Assembling the Lift

DO NOT overtighten mounting hardware. This will damage mounting brackets.

Operating the Lift

Although Invacare recommends that two assistants be used for all lifting preparation, 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 health care professional for each individual case.
Make sure there is an audible click when mounting battery on the battery charger to confirm proper mounting. Otherwise, injury or damage may occur.
DO NOT exceed maximum weight limitation of the patient lift. The weight limitation for the RPL450-2 is 450 lbs. The weight limitation for the RPL600-2 is 600 lbs.
ALWAYS keep hands and fingers clear of moving parts to avoid injury.

Using the Sling

Use an Invacare approved sling that is 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 patient and 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 sling(s) for wear, tears, and loose stitching. Bleached, torn, cut, frayed, or broken slings are unsafe and could result in injury. Discard immediately.
DO NOT alter slings.
Be sure to check the sling attachments each time the sling is removed and replaced, to ensure that 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 forwards or backwards.
When connecting slings equipped with color coded straps to the patient lift, the shortest of the straps MUST be at the back of patient for support. Using long section will leave little or no support for patient's back. The loops of the sling are color coded and can be used to place patient in various positions. The colors make it easy to connect both sides of the sling equally. Make sure that there is sufficient head support when lifting a patient.

Lifting the Patient

When using an adjustable base lift, the legs MUST be in the maximum Opened/Locked position before lifting the patient.
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 that 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 this problem.
Adjustments for safety and comfort should be made before moving the patient. 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. Warranty will be voided.
During transfer, with patient suspended in a sling attached to the lift, DO NOT roll caster base over uneven surfaces that could cause the patient lift to tip over. Use steering handle on the mast at all times to push or pull the patient lift.
Invacare does not recommend locking of 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 that the rear casters be left 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.

Transferring the Patient

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 that 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 this problem.
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 that it is properly attached before the patient is removed from the bed or chair.
Mast pivot under the rubber boot must be tight to ensure safe use of the patient lift. Bolt must be checked at least every six months in conjunction with periodic maintenance.

Performing Maintenance

Maintenance MUST be performed ONLY by qualified personnel.
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, replacement must be made.
Casters and axle bolts require inspections every six months to check for tightness and wear.
After the first twelve 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. Make this inspection every six months thereafter.
Regular maintenance of patient lifts and accessories is necessary to assure proper operation.
DO NOT overtighten mounting hardware. This will damage 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. Make this inspection every six months.

Electrical and Grounding

GROUNDING INSTRUCTIONS
DO NOT, under any circumstances, cut or remove the round grounding prong from any plug used with or for Invacare products. Some devices are equipped with three-prong (grounding) plugs for protection against possible shock hazards. Where a two-prong wall receptacle is encountered, it is the personal responsibility and obligation of the customer to contact a qualified electrician and have the two-prong receptacle replaced with a properly grounded three-prong wall receptacle in accordance with the National Electrical Code. If you must use an extension cord, use ONLY a three-wire extension cord having the same or higher electrical rating as the device being connected. In addition, Invacare has placed RED/ORANGE warning tags on some equipment. DO NOT remove these tags.
Carefully read battery/battery charger information prior to installing, servicing or operating your patient lift.

Radio Frequency Interference

Most electronic equipment is influenced by Radio Frequency Interference (RFI).

The Invacare Patient Lift is designed to provide a maximum of safe, efficient and satisfactory service with minimum care and maintenance.

All parts of the Patient Lift are made of the best grades of steel, but metal to metal contact will wear after considerable use.

There is no adjustment or maintenance of either the casters or brakes, other than cleaning, lubrication and checking axle and swivel bolts for tightness. Remove all debris, etc. from the wheel and swivel bearings. If any parts are worn, replace these parts immediately.

If you question the safety of any part of the lift, contact your Dealer immediately and advise them of the problem.

Lubricating the Lift

The Invacare lift is designed for minimum maintenance. However, a six month check and lubrication should ensure continued safety and reliability.

Keep lift and slings clean and in good working order. Any defect should be noted and reported to your dealer as soon as possible.

The casters MUST swivel and roll smoothly. A light grease (waterproof auto lubricant) may be applied to the ball bearing swivel of the casters once a year. Apply more frequently if the casters are exposed to extreme moist conditions.

Lubricate all pivot points. Wipe all excess lubricant from lift surface.

Lubricate the following points:

1. Hangar Bar
2. Boom Mounting Bracket
3. Boom/Mast Mount
4. Mast Mounting Bracket

Detecting Wear and Damage

It is important to inspect all stressed parts, such as slings, hanger bar and any pivot for slings for signs of cracking, fraying, deformation or deterioration. Replace any defective parts immediately and ensure that the lift is not used until repairs are made.

Cleaning the Sling and the Lift

Laundering should always be done with dark colors. The sling should be washed regularly in a water temperature not to exceed 180°F (82°C). Refer to the sling user manual for complete cleaning instructions.

A soft cloth, dampened with water and a small amount of mild detergent, is all that is needed to clean the patient lift. The lift can be cleaned with nonabrasive cleaners.

Replacing the Boom Actuator

DO NOT overtighten the nut and bolt. This damages the mounting bracket.

1. Remove the nut, washer and shoulder bolt that secures the actuator to the mast mounting bracket.

N/A	LO BAT	Center of Display Window	Indicator is shown in the display window to notify when battery is low.

Weighing the Patient

The weight capacity is limited to the lowest rated capacity of any one of the components in use (e.g. 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 (e.g. pencils, pens, fingernails, etc.) Otherwise damage to the key pad will result.

1. Attach sling straps to the hangar bar. For proper attachment instructions refer to Attaching a Sling.
   For improved accuracy on the 450 and 600 Reliant lifts, attach all sling straps to the center hooks on both sides of the hangar bar. However, patient comfort may require a different configuration of sling straps.
2. Press the ON/OFF key. The display will indicate the last weight that was measured. The word "LOCK" will be seen in the display box.
   The ZERO key is pressed in order to avoid capturing the weight of the sling and the hardware. If the ZERO key is not pressed the weight of the sling and the weight of the hardware will be included in the weight displayed. NOT ZERO-ING OUT WILL GIVE A FALSE READING OF THE USER'S TRUE WEIGHT.
3. Press the ZERO key. When the ZERO key is pushed the following will happen:
   1. The scale will reset to zero and the word "ZERO" will appear in the display.
   2. The lock function will then be turned off and the word "LOCK" will disappear from the display.
      The scale is now active and continually updating the weight display.
4. Place the patient in the sling. For patient placement instructions refer to Operation.
5. Activate the lift mechanism to raise the patient until they are completely supported by the lift. For patient lifting instructions, refer to Lifting the Patient.
6. Note the weight display.
7. When the weight display becomes stable press the LOCK button to lock the weight display. This will be indicated by the word "LOCK" appearing in the display window.
   Should it be necessary to unlock the weight while the patient is still supported by the lift, the UNLOCK button may be pressed. The weight will unlock and the word "LOCK" will disappear from the display window. The weight value will then be updated. Once the weight becomes stable the weight can be locked again by pressing the LOCK button.
   Stable being defined as the weight fluctuating two tenths of a pound. For example, a patient weighing one hundred pounds, the scale will fluctuate between 99.8 and 100.2 until the LOCK key is pressed. Fluctuation of the weight displayed is normal as noted above. Press the LOCK button to lock the weight.
   The UNITS button can be pressed to toggle between units of pounds and kilograms. This is indicated by lb or kg appearing in the display window.
8. The lift may now be lowered and the sling removed from the patient.

The patient's weight will continue to be seen in the display window. The display will turn off automatically after a two minute period of nonuse [no changes in weight exceeding five pounds (two kilograms)]. You can NOT adjust the time delay for automatic shut off. After the display has turned off, the weight may be recalled by pressing the ON/OFF button. The unit can be turned off by pressing the ON/OFF button a second time.

Replacing the Battery

The scale is powered by a nine volt alkaline battery that Assembled Scale should provide approximately 1500 readings before needing replacement.
