All SUNRISE MEDICAL products are designed for minimal maintenance, but some regular safety checks are necessary.
SUNRISE MEDICAL recommends that the following checks be made every day, before the hoist is used.
• Ensure that the front castors of the hoist move normally.
• Ensure that the spreader bar rotated and rocks freely.
• Check that the spreader bar is securely attached to the boom.
• Ensure that the legs of the hoist open and close normally.
• Ensure that the hand control unit is being used properly.
• Check that the emergency stop button works properly.
• Check for wear on the hooks. Do not use slings which show signs of wear or damage in the lifting straps or sling body.
