NOTE– HYDRAULIC PUMP
1. Use pump to raise boom to position for lifting patient.
2. DO NOT lift up on end of boom to position for lifting patient as this causes air
to be drawn in under ram, preventing pump from lifting when handle is pumped.
3. DO NOT press down hard on handle when bottom of stroke is reached.
4. It is a common occurrence after a few hours of non-use for the boom to lower
with no weight suspended from the end of the boom. This does not indicate a
faulty pump but is a trait common to hydraulic equipment.
5. If trouble develops with the hydraulic pump, remove it and call your Sunrise
Medical Supplier to receive an RMA. Provide serial number and date purchased.
DO NOT attempt to lift someone with a faulty hydraulic pump.
Do not wash slings with bleach. Bleach will damage material.
Slings can suffer damage during washing and drying.
Always check slings before use. Bleached, torn, cut, frayed, or broken slings
are unsafe and could result in serious injury or death to patient. Destroy and
discard worn slings. Do not alter slings.
