8. Raising and lowering the boom (hydraulic models)
Never loosen or unscrew the retaining bolt of the hydraulic jack unless you are an authorized compe-
tent engineer. Never load whilst user needs to rotate hydraulic jack. If the user intends to rotate
the jack strongly, it may impact the patient or cause unforeseen danger to patient and/or caregiver.
The raising and lowering of the boom is achieved by a powerful hydraulic ram, which is operated
by two simple controls. The release valve, which is identified by a silver star shaped knob, and
the pump handle which is a long lever on the side of the hydraulic unit to raise the boom. The
valve is closed by gently turning the knob fully clockwise. When closed, pump the long handle
with smooth even strokes for maximum effect. The handle strokes from an upright position
through an arc of 90 degrees. Leave the handle in the upright position when not in use.
DO NOT force the handle beyond the upper or lower stops. The hydraulic unit can be rotated to
allow the handle to be used from either side of the lift. To lower the boom, turn the release valve
anti-clockwise. The release valve is progressive, the more it is opened the faster the descent.
The valve is restricted so even when fully open the descent is controlled. This facility allows for a
"hands free" descent. If the release valve is opened a fraction (a quarter turn) a very slow speed
of descent will allow the caregiver to work "hands free" while assisting or comforting the patient.
REMEMBER to close the release valve before commencing lifting operations. The release valve
only requires gentle pressure to open or close. DO NOT apply excessive force to the release
valve, either to close or to open. It is not necessary and will only damage the valve.
When lowering a patient, open the valve very slowly. Rapidly opening the valve may cause
the boom to lower quickly which may cause injury to the patient.
9. Slings
The selected sling is attached to the spreader bar hooks. Each sling is supplied with instructions.
Please study the instruction guide for the lift and sling before using. Once the correct sling has been
selected for the patient, attach it to the spreader bar hooks.
NOTE: For detailed fitting instructions, please refer to the user guide supplied with each sling.
Joerns Healthcare recommends slings are checked regularly and before use for fraying or
damage. DO NOT use slings that are worn or damaged.
HOYER RECOMMENDS THE USE OF GENUINE HOYER PARTS. Hoyer slings and lifters
are not designed to be interchangeable with other manufacturer's products. Using other
manufacturer's products on Hoyer products is potentially unsafe and could result in
serious injury to patient and/or caregiver.
Refer to maximum weight capacity of lift. Sling capacity is limited by the maximum
capacity of the lift.
