YOUR LIFT is for transferring patients only. Do not use the lift for any other purpose.
ALWAYS carry out the daily checklist before using the lift.
Arjo ceiling lifts are specifically designed for Arjo ceiling rail systems, slings and accessories.
Slings and accessories designed by any other manufacturer are prohibited and will prevent
Arjo from being able to guarantee a safe transfer. Use only Arjo Ergofit slings and accessories
to maintain patient safety and product utility.
Arjo ceiling lifts are intended to be used for patients within the specified weight limit indicated
for the lift. Do not attempt to lift more than the weight limit indicated.
Before attempting to transfer, the patient must be assessed by a qualified professional.
Arjo ceiling lifts must be used by a caregiver with proper training to work with the patient to be
transferred. This patient lift should never be used by a patient on their own.
ONLY trained and qualified caregivers should transfer a patient. DO NOT attempt to use the lift
if you have not been properly trained to do so.
ALWAYS be prepared before attempting to transfer a patient.
DO NOT use a sling that is not recommended for the lift.
NEVER use a damaged, torn or frayed sling.
ALWAYS place the sling around the patient according to the instructions enclosed.
FOLLOW the lifting procedures outlined in this manual.
USE all controls and safety features only according to the rules specified in this manual.
Never attempt to force a control or button on the lift.
