caregivers with proper training to work with the person
to be transferred.
Warning: Only trained and qualied caregivers should
transfer a person. Do not attempt to use the lift if you
have not been properly trained to do so.
Warning: Always carefully plan and be prepared
before attempting to transfer a person.
Warning: Do not use a sling that is not recommended
for the lift.
Warning: Never use a damaged, torn or frayed sling.
Warning: Always place the sling around the user
according to the sling user instructions.
Warning: Follow lifting procedures outlined in the
“How to Use a Patient Lifter” manual.
Warning: Use all controls and safety features only
according to the rules specied in this manual. Never
attempt to force a control or button on the lift.

Caution: DO NOT lift up on end of boom when
positioning to prepare for lifting patient as this causes
air to be drawn in under ram, preventing hydraulic
pump from lifting when handle is pumped.
Caution: DO NOT press down hard on handle beyond
its normal downward stopping point.
Caution: 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.
Caution: If trouble develops or you have questions
regarding the hydraulic pump, call Joerns Healthcare
Customer Care at 1-800-826-0270 (be sure to provide
your serial number and date purchased). DO NOT
attempt to lift someone with a faulty hydraulic pump.
Warning: DO NOT wash slings with bleach. Bleach
will damage material. Slings can suffer damage during
washing and drying.
Warning: Possible Injury or Death. Always check
slings before use. Bleached, torn, cut, frayed or
broken slings are unsafe and could result in serious
injury or death to patient/caregiver. Destroy and
discard worn slings. DO NOT alter slings.
Warning: Inside center attachment points on cradle
are used only for Hoyer slings with chains or straps.
The four outside attachment points are used for Hoyer
4-point slings.
Warning: Possible Injury or Death. Cradle Center
Post must protrude below the bottom of the cradle
center pivot assembly (approximately 1/16"). If cradle
center post is ush or recessed, excessive wear may
have occurred. Worn cradle parts could fail resulting in
serious injury or death to patient and/or attendant.

bar/6-point cradle and adjusting lever handle.
2. Insert mast in base sleeve (Figure 1). Be sure
notch on end of mast ts over bolt in bottom of
mast sleeve. Mast must lock into position in base
sleeve, making it impossible to rotate. Check
carefully to be certain mast cannot rotate.
3. Make certain boom points in same direction as
base legs. Thread mast safety lock and stud
into threaded hole in mast sleeve. Tighten rmly,
locking mast into base (Figure 2). Keep mast and
base locked at all times except when removing
mast from base for storage.
4. Insert boom end into hole in yoke hinge at the top
of mast. Fasten bolt and nut (Figure 3). Be certain
hex of bolt head ts into formed hex on side of
hinge and that plastic washer is under lock nut.

wrench
1. Observe orientation of “U” bracket (3) and rotation
limit bracket (4) prior to removing pump from lift.
2. Remove hydraulic pump from lifter by removing
bolts at mast and boom attaching points. Place on
suitable work surface.
3. Loosen nut (2) by three turns at base of pump
using the 9/16" combination wrench. If the stud
turns while loosening, use the 5mm hex wrench to
prevent it from turning.
4. Check tightness of stud using the 5mm hex
wrench. Firmly tighten the stud by turning in a
clockwise direction when viewed from the bottom.
5. Verify all components 1, 2, 3, 4, and 5 are correctly
assembled (Figure 9).
6. Tighten nut (2) until it lightly contacts the nylon
washer (1). Loosen the nut (2) by 1/2 turn so
that the pump rotates freely in “U” bracket (3).
Check that the stud is still tight using the 5mm hex
wrench.
7. Reassemble the pump to lift (reverse of step
2). Tighten nuts until contact is made with “U”
brackets of mast and boom. Then loosen by 1/2
turn. Pump should be free to rotate. Verify that
“U” bracket (3) and rotation limit bracket (4) are
correctly oriented to mast per diagram.
8. Check for free rotation of pump after assembly.
Caution: The pump should rotate freely prior to lifting
a patient.
Caution: Place the pump handle in a comfortable
position prior to lifting a patient. Do not attempt to
rotate the pump while lifting a patient.
