Maintenance & Care
NOTE– HYDRAULIC PUMP
1. Use pu p to raise boo to position for lifting patient.
2. DO NOT lift up on end of boo to position for lifting patient as this causes air
to be drawn in under ra , preventing pu p fro lifting when handle is pu ped.
3. DO NOT press down hard on handle when botto of stroke is reached.
4. It is a co on occurrence after a few hours of non-use for the boo to lower
with no weight suspended fro the end of the boo . This does not indicate a
faulty pu p but is a trait co on to hydraulic equip ent.
