According to the Sabina II instruction guide, “During passive/active lifting of patients, the wheels should be unlocked so that the lift can be moved to the patient’s center of gravity.” In general we would advise following that guideline, however there may be some situations where you wish to lock the rear wheels during lifting or lowering. For example, if you are on a slippery or uneven surface, or if you wish to turn the Sabina immediately following lifting, you might want to lock one or both of the wheels in advance of the lifting procedure. To make a lateral turn, it’s usually easier to lock the wheel on the side to which you are turning in order to lessen the amount of torque placed on your back. Once the Sabina is facing the desired direction, simply unlock the wheel and proceed to push the lift forward.
