1.3 Intended proper use
The Patient Hoist is for use in care facilities, hospi-
tals and home purposes. The hoist described here-
in is exclusively for moving (lifting and transferring
a patient in a sling).
The max carry load of the hoist is 250 kg.
The Patient Hoist may not be used for longer
transport distances, or over to other floors, or trav-
el over uneven surfaces. It may not be used for
other purposes such as transporting other objects,
as it is not designed for this purpose. The Patient
Hoist may be used indoors only! Do not use the
Hoist near life-supporting equipment.
1.4 Operating comfort
The Patient Hoist is equipped with an electric
hoisting unit, jamming protection, low charge pro-
tection, emergency lowering, emergency OFF
function and a rechargeable battery.
The rechargeable battery makes the Patient Hoist
independent of an external power supply for a
certain period of time (depending on the charging
capacity of the rechargeable battery) and thus
increases mobility during its use.
By activating the foot pedal, the transport base
frame spreads apart and thus increases stability.
The rear swivel castors can be easily locked by
pressing the locking lever lightly with your foot.
Using the hand switch, the lifter arm can be moved
up or down without any jerky movement, and step-
lessly via the motorised drive unit.
1.5 Accessories (sling and hoist)
Various sling systems are available as accessories
for individual seating requirements and areas of
applications.
Use only REBOTEC accessories as only these
can assure a trouble-free and safe function.
2. Warranty

6. Safety advisories during use
When using the Patient Hoist, the fol-
lowing safety advisories must be ob-
served:
Attention! Operating instructions!
Before the first use, the User Instructions must
be read completely in order to avoid faulty opera-
tion or hazards.
Before each use, check the Patient Hoist for
visible damage or deficiencies.
Operating and adjusting the Patient Hoist must
be done only by persons who are knowledgeable
and trained on how to properly handle the Pa-
tient Hoist. This requires the ability to use the
unit with the patient.
Patient Hoists used in wet rooms may be ex-
posed to ozone moisture, chlorine and heat,
which can lead to oxidation that appears as a
white coating.
When functional faults or damage of any type
occur, then the Patient Hoist may not be used.
Danger of breakage!
The maximum allowable load of 250 kg may
not be exceeded because no safe operation
can be assured.
Whenever using a sling, be sure that it is secure-
ly hung to the carrier of the Patient Hoist. Do not
use any sling that shows signs of damage.
Do not place any objects between the main col-
umn and the drive axis. No perpendicular loads
may be applied to the drive axis.
The patient must not hold onto the drive axis.
No weight loads may be hung onto the carrier for
an extended time period.
Danger of injury!
The Patient Hoist may not be operated while it is
being charged up.
The Patient Hoist may be used only inside on
even, slip-free surfaces. Using the Patient Hoist
on slopes, grades or inclinations must be avoid-
ed due to the increased risk.
Use caution when travelling in tight spaces.
Paths used by the Patient Hoist must be cleared
before they are travelled on.
Sudden movements and pushing, as well as
patient-swinging must be avoided because of an
increased risk of an accident.
Never leave the patient unsupervised when us-
ing the Patient Hoist! An unforeseen movement
or action by the patient may lead to a risk of inju-
ry.
In the event of an emergency lowering of the
patient, use extreme caution to avoid putting the
patient in danger. In difficult situations, seek the
assistance of another person.
Check to be sure the connection between the
carrier and the lifter arm is secure.
Danger! Function hazard!
It must be assured that no moisture reaches
inside the electrical systems. (Observe protec-
tion class!)
Do not open up the control / drive / battery unit or
manual switch systems!
Do not charge up the rechargeable battery in wet
rooms (e.g. bathrooms, shower stalls).
In the event the electric jamming protection does
not function (drive unit must not run when there
is blocking), the Patient Hoist must not be used.
Watch out for possible electromagnetic disturb-
ances from unit(s) such as mobile phones, medi-
cal equipment!

bracket and the main column (A), all the way
through, and fasten it with the M10 cap nut.
Next from the front using an M12 Allen key, screw
on the grip handle firmly to the bracket. The grip
handle is now firmly connected and fixed to the
base member (C).
Cut off both cable ties after assembly. Remove the
protective film around the drive shaft and at the
end of the lifter arm.
Step 7: Install the lifter axis
To attach the drive motor
to the lifting axis, remove
the safety ring (1) and the
pin (2) from the borehole
of the lifting arm (B).
Next raise the lifter arm
(B) and align the borehole
of the lifting axis with the
lifter arm.
The lifter arm is fixed by
inserting the pin and in-
stalling the safety ring.
Be sure that the safety
ring is completely in-
stalled and closed!
Step 8: Install the carrier
The carrier (G) (in the accessories) for the sling is

10. Charging the battery
10.1 Rechargeable battery
If the lifting and lowering of the lifter arm becomes
noticeably slower, then the battery charge is too
low.
Recharge the battery as soon as possible!
This extends the lifetime of the rechargeable
battery. Rechargeable batteries that are not
used for an extended period of time should be
recharged every 6 months in order to avoid
low charges. Otherwise the charging capacity
of the battery is negatively impacted. The life-
time of the batteries (according to the manu-
facturer, is up to 5 years) depends on the
loading and the charge level.
10.2 Connecting and charging
Follow the safety instructions!
Check over the charging unit to be sure that the
connector cables or the plugs are not damaged.
DO NOT USE cables or plugs that are damaged!
Use only REBOTEC charging units.
Check the power mains voltage (section 7.2) and
the corresponding circuit protection for the
charging unit.
Do not open up the battery or charging unit un-
der any circumstances!
The Hoist may not be used or operated while
the battery is charging!
When charging the battery, first remove the protec-
tive lid (1) from the jack of the control unit (K). Next
insert the plug (2) into the jack and then plug the
charging unit (3) in the power outlet.
Depending on the battery charge level, the charg-
ing process can be as long as 20 hours. If the
charging process lasts longer than 21 hours, then
the rechargeable battery or the charging unit is
defective.
When the rechargeable battery is charged up, first
unplug the charging unit from the power outlet and
then remove the plug of the charging unit (2) from
the jack of the control unit (K). Lastly cover the
jacks again with the protective lid.
Whenever the charging unit is not in use,
do not wind the connector cable around
the housing of the charging unit. This leads
to damage to the cable and to the plug.
10.3 Charge level
An indicator lamp (LED) for the charge level is
located above on the cover of the control unit (K).
The display is visible when you look directly at the
viewing window from the front.
LED dark: No power supply
LED green: Battery is charged,
power supply at hand
LED yellow: Battery is charging
LED blinking Charge battery –remaining
Yellow: charge is 20%.
Peeping tone: Battery charge < 20%
Only one remaining lift cycle is
possible! Battery must be
charged –otherwise the low
charge protection system will
block the drive unit.
.
11. Emergency OFF function
When pressing the red emergency OFF button, it
locks into position. The drive system is interrupted
and cannot be operated with the manual switch. It
must be activated in emergency situations and/or
when proper operation of the Patient Hoist is im-
paired.
By rotating the emergency OFF button clockwise,
it will pop back out and thus be released. The drive
unit can then be operated using the manual switch.

12. Manual switch
The drive unit is activated with the manual switch
(stepless adjustment) and activates the “lifting”
and “lowering” of the lifter arm. For the desired
action, the button is kept pressed down (LED illu-
minates). When releasing the button, the drive
automatically stops (LED does not illuminate).
13. Wheel brakes
Both wheel brakes are an important safety feature
whenever using the Patient Hoist. The back swivel
castors are equipped with wheel brakes and allow
the locking of the rear wheels.
Warning! Danger of tipping over!
Both rear wheels must be braked.
Press the wheel brake
levers down with your
foot. The wheels are
now locked and the di-
rection is secured.
Be sure that the wheels
are not swivelled in-
wards.
The wheel brakes can
be released simply by
lifting up the lever with
your foot.
14. Emergency lowering / jamming protection
14.1 Electric emergency lowering
A fully charged battery has a capacity of 50 lift-
ing/lowering cycles with a load. When the battery
is almost empty, the yellow LED blinks and an
acoustic peeping tone is given off.
One lifting/lowering cycle is still possible, but then
the rechargeable battery must be recharged!
14.2 Mechanical emergency lowering
In the event the patient becomes exposed to an
emergency situation, or an electrical defect occurs
with the drive motor, or the control unit fails, or the
battery is completely uncharged, then it becomes
necessary to use the mechanical emergency low-
ering system.
Warning! Risk of injury!
When using emergency mechanical lowering,
do not stand under the lifter arm.
By rotating the red grip (A) counter clockwise at
the end of the stroke tube (B), the lifter arm can be
lowered until it reaches the striker.
Warning! Do not rotate the tube (B)!
14.3 Jamming protection
A pin contact is located
just beneath the motor. If
the lifter arm is loaded and
lowered, and travels
against an obstruction,
then the lifter arm raises
and the contact to the mo-
tor is interrupted.
Do not put the Patient Hoist in operation if the still
motor runs when the contact is interrupted!
15. Stability –spreading the base
The foot pedal allows the spreading of the base
members (left and right) and thus facilitates mov-
ing the unit to the area of use. Press the foot pedal
all the way down to the stop.
Warning! Danger of tipping over!
Spread the base members only when the rear
wheel locks are fully disengaged!
Not spread apart:

16. Lifter arm (carrier for the sling)
In the area of suspension, the carrier is equipped
with a Velcro padding (A). It serves as protection
against bumping injuries to the patient and for cov-
ering the bolt assembly. We recommend that the
padding be used because of the aforementioned
reasons.
The carrier is for hanging slings in which the pa-
tient can be held, lifted and transferred.
The carrier can be rotated 360°.
Hanging the sling must be done using all four
hooks so that the load is evenly distributed. Abide
fully to the maintenance instructions for the carrier
(see page 10, section 20).
Depending on the application, there are several
different types of sling systems offered by REBO-
TEC. To assist you in selecting the most suitable
sling system, a guide is available (see page 5,
section 8).
17. Lifter arm (carrier with PW500 scale)
Patient Hoist with scale
If the Patient Hoist is equipped with a PW 500
scale, then also use the additional User Instruc-
tions for the scale(User Instructions-No. 02.09.107)
This User Instructions booklet is delivered when a
Patient Hoist is purchased with a scale.
You may also order or download it from our web-
site www.rebotec.de in the event you wish to pur-
chase it later.

19. Care
In general the Patient Hoist can be
cleaned using a mild conventional cleaning
and disinfecting agent. Simply wipe the
chair with clean water and cloth, and then
wipe dry with a clean cloth.
Maximum cleaning temperature of
65C must be observed!
The Patient Hoist must not be washed
inside an automatic washing unit!
Do not use an abrasive scouring agent or cleaner
(read the product instructions!) that contain ag-
gressive solvents (acids, thinners, benzene). Do
not use stiff cleaning brushes, as these will dam-
age the plastic surfaces or cause deposits to build
up on the plastic parts and other materials.
Emergency lowering
The emergency lowering mechanism may not be
treated with oil, grease or other lubricant. This will
lead to faulty function when lowering.
The screws at the clamping lever may not be tight-
ened or loosened. In the event of faulty function of
the emergency lowering, a new adjustment must
be carried out by a qualified maintenance service-
man.
20. Maintenance
Accidents or damage may be caused by the late
detection of wear and/or improper use, as well as
irregular or too little maintenance.
For safety reasons and for preventing ac-
cidents, the Hoist must undergo a com-
plete maintenance at least once a year.
(Refer to the Medical Products Act and the
local regulations).
Maintenance scope
Check at regular intervals:
(The maintenance time intervals depend on the
frequency of use and the condition of the product).
The product for visible damage (cracks, break-
age, loose parts, instability).
All screw connections for tightness (especially
the wheels and carrier)
Emergency lowering at least semi-annually
(malfunctions –carry out maintenance!)
Rolling smoothness, castor function (replace any
defective castors).
Drive unit function, test manual switch. (Replace
defective articles).
Cable connections and plugs for damage.
Sealing edges of the control and battery unit.
Test the emergency OFF function.
Inspect the accessories for deficiencies.
Maintenance of the carrier
The bearing unit must be checked over at each
maintenance session.
Remove the Velcro padding (1) and push the car-
rier (G) upwards.
If dirty, clean the bearing by lightly wiping it with
a cloth.
Replace the bearing (3) if there is any damage or
functional deficiency.
Replace the bolt (2) if there is excessive wear
and/or damage.
Replace the padding if it is damaged.
