7.02 Safety functions
Only use the emergency stop button and emergency lowering functions in
emergencies. If it has been necessary to apply the emergency/safety func-
tions due to an error on the lifter, the supplier must be contacted prior to
using the lifter again.
Activating the emergency stop function
Should the lifter not respond to the func-
tions selected on the hand control when it is
in motion, push red button on top of battery.
When the emergency stop function is applied,
the lifter ceases to function.
To release the emergency stop, take o󰀨 battery
by using thumb and index/middle nger to push
buttons on battery sides, and pull battery out.
To replace the battery again, grab battery on
sides and steer battery base on steering pin,
and push in place.
In order to disconnect the lifter from mains sup-
ply, pull the mains plug out of the power out-let.
Activating the emergency lowering function
If the lifter fails to lower, activate the following:
1. Press the arrow key on the control box.
This functions as an emergency lowering
in case the hand control does not work.
If the lifting boom does not lower
2. Turn the red knob on the lifting boom in the
direction of the arrow (Optional)
Use of brakes
The rear castors are tted with brakes. Apply
the brake by stepping on the lower kick pedal.
To release the brake, kick the top part of the
kick pedal.
In daily operating the lifters castors are not
locked for the lifter to center itself according
to the patient’s line of gravity. If the brakes
are activated in these situations, shearing of
the patient’s skin or the patient being pulled
out the lifter is a potential hazard. Individual
circumstances might lead to clinical assements
where the lifter castors must be locked.
The brakes must be activated when the lifter is parked.

8.00 Use of Mobile lifter
Lifting hanger
The lifting hanger can be mounted on the mobile lifter without the use of any
tools.
1. Hold the lifting hanger in the right hand
and press the yellow button using the
index nger as shown. The slot on the
lifting hanger’s top cover must face up
(g. 1).
2. Insert the lifting hanger in the slot on the
side of the lifting hanger’s top cover (g. 2).
3. Check that the yellow button has returned
to its locked position by checking that it is
ush with the cover of the lifting hanger
and that the strap attachment can rotate
freely (g. 3).
Fig. 1
Fig. 3
Fig. 2
8.01 How to use the Sling
Use slings with 4-6 lifting straps designed for tting on Guldmann lifting han-
ger as shown in the sling manual.
The Lifter can be positioned under a bed. It can be moved through normal doors.
The lifter can be used in wet areas, but must not be exposed to splash water.
The lifter is protected against corrosion (See 11.00 Environmental conditions).
The lifter can be used for multiple users. When moving the lifter to another
user, perform normal hygienic disinfection.

Lifting to and from a sitting position
When lifting from, e.g., a wheelchair, move the lifter towards the person to be
lifted. Lifting boom and lifting hanger should be level with the chest and posi-
tioned above the middle of the thigh.
Position the lifting hanger parallel to the user’s shoulders. Now t the lifting
sling to the lifting hanger. For instructions on how to t the sling, see separate
Guldmann Slings manual for details.
Lifting to and from a lying position in bed
Position lifting boom and lifting hanger right over the bed. Now pull the lifter
back until the lifting boom and lifting hanger are positioned above the center
of the person to be lifted. The lifting hanger and lifting boom should be paral-
lel with the person’s shoulders. Now t the lifting sling to the lifting hanger.
For instructions on how to t the sling, see separate Guldmann Slings manual
for details.
Working with the mobile lifter
To obtain a correct working posture when moving the lifter, the caregiver
should always, by placing one leg in front of the other, push the lifter in a for-
ward motion thus utilizing his/her body weight.
Turning the lifter should be carried out by two persons, otherwise, stand
alongside the lifter and push on the side of the mast thereby minimizing the
center of rotation. It is a good idea to make the heaviest point of the lifter the
center of rotation. If there is limited space, you can use your foot to push on
the chassis of the lifter in the direction you wish to turn.
Hook the top set of straps (from the back) to the hooks facing the user. Hook
the lower set of straps (from the legs) to the hooks facing away from the user.
Lifting hanger, 4 attachment points
Caution!
Be careful when attaching the lifting sling’s straps on the hooks. Check
that the straps have been correctly placed in the lifting hanger’s hooks.
When pressing the up button on the hand control to lift the user, check
again that all straps remain correctly placed in the lifting hanger’s
hooks (Fig. 1).

AA
From a chair, wheelchair or other sitting positions
Place lifting sling behind user’s back, e.g., between the back of the chair and
the user’s back.
The center band of the lifting sling should follow the user’s spine. As for the
slings type Active, the strap showing the size of the sling should be opposite
the spine. Bring the leg straps along the outer thigh and then under the thigh
between the back of the knee and the hip.
Now cross the leg straps in front of the user.
All four straps are now ready to be mounted onto the lifting hanger.
Lying position in bed, on a mattress or on the oor
Turn the user on his side. Place the high back sling so that its upper edge
is ush with the top of the user’s head. Put the sling on the user so that the
center band follows the spine. Turn the user on his back and pull the sling
out. Bring the leg straps under the thigh and cross them over.
All four straps are now ready to be mounted onto the lifting hanger.
If in doubt about how to use the sling, please contact your supplier.
Guldmann cannot be held responsible for any faults or accidents that may
occur due to incorrect positioning of the lifting hanger, or for reasons of inade-
quate attention paid by helpers or the user.
8.02 Cleaning and disinfection
We recommend that the products and the parts patients and caregivers can
come in contact with, are cleaned with a damp cloth using warm water and a
mild soap solution.
When disinfection is needed, use disinfectant wipes with up to a 85% solution of
isopropyl, or a damp cloth using warm water and a disinfectant cleaner, e.g., an
