1.05 Important/Precautions
• Read the instructions carefully before using the GH3 and in connection
with cleaning and service of the hoist.
• The GH3’s maximum load must never be exceeded.
• The GH3 may only be used to lift a person.
• The red strap for the emergency stop and the emergency lowering must
be adjusted to the healthcare professionals reach, and must not be removed.
• The GH3 must not be used where there is a risk of it being splashed with
water.
• If a defect appears during use of the GH3, stop using the hoist and contact
the Guldmann Service Team for repairs.
• The GH3 is controlled by a microprocessor PCB, which can be damaged by
static electricity if touched without the necessary precautions, (see point 1.08)
• The electronics may only be serviced by Guldmann approved service
technicians.
• The lifting hanger must not be mounted or replaced when the GH3 hoist is
positioned over the user.
• Do not modify this equipment without the authorization of the manufacturer
• The GH3 needs special precautions regarding EMC and needs to be installed
and put into service according to the EMC information provided in Chapter 11
EMC Information.
• Portable and mobile RF communications equipment can a󰀨ect the GH3.
• Accessories, transducers and cables must always be original Guldmann
components. The use of other spare parts than those supplied by Guldmann
may result in poor EMC protection. This may cause damage to the GH3 lifting
module as well as electrical products in the nearby surroundings.
• The GH3 should not be used adjacent to or stacked with other equipment
and if adjacent or stacked use is necessary, the GH3 should be observed to
verify normal operation in the conguration in which it will be used.
• Transport of this equipment should only be undertaken after conditions
described in section 3.00 (Environmental conditions).
• Nothing should be connected to the USB port when the device is in use with
a user.
• GH3 is not intended for use in oxygen rich environments
• Any serious incident that occurred in relation to this device should be reported
to the manufacturer and the local competent authority.
Re: EMC
If electromagnetic or other inuences occur between this product and other
products, these products must not be used together.
1.06 Load limits on GH3 system
Read the label which indicates the maximum load limits for each component.
The component, e.g. lifting hanger, lifting sling, etc. labelled with the lowest
load limit determines the maximum load limit for the entire system.
This maximum load limit must not be exceeded.
Please note that the max load may change when di󰀨erent components are
used, such as lifting hangers, lifting slings, etc.

1.08 Placing a new GH3 Hoist in an existing rail system
Please notice that when, placing a new GH3 hoist in an existing rail system it
must be ensured that:
• The rated max load of the rail system, must be equal to or higher than the
max load of the new hoist.
– If there is no max load mentioned on the rail system, the rail system
must then be checked according to the guideline in the Installation
guide (distance between bracket according to max load)
– If the brackets are not visible, then a load test with 1,5 x max load of
the hoist must be performed for a minimum of 20 min. The deection of
rails must not be higher than 1/200 of the length of the rail.
– If it is not possible to do any of the above mentioned, please contact
Guldmann or their representative.
• If the rail system can not be rated to the same max load as the hoist,
then extra brackets must be installed according to the Installation
guide (distance between bracket according to max load).

Class I equipment
Fixed rail systems are class I equipment and must be installed by a qualied
technician or by Guldmann Service Team.
Equipment is disconnected from Supply Mains by breaking the mains breaker
switch.
Emergency stop device
The emergency stop device must be reset in order to connect power to the
product. To do this, push the yellow reset button (see point 2.09).
1.09 Transformer
GH3 is equipped with batteries that require regular recharging. The transfor-
mer for charging and the battery charging point must be connected by a qua-
lied engineer or by Guldmann Service Team.
Safety concerning static electricity (ESD)
Service technicians and installers must use an ESD-safety package
consisting of a mat, a ground wire, and a bracelet. The technician/installer
connects the mat to a grounding point. The technician/installer must then
put on the bracelet and connect it to the mat. If it is not possible to nd a
grounding point, the mat and the bracelet must be used as a minimum.
Only then is it allowed to work with the PCB or components where it is pos-
sible to come into contact with the PCB.

1.11 Lifting sling
A lifting sling with four to eight lifting straps designed for mounting on hooks
should be utilized when using a Guldmann lifting hanger. Place the straps on
the hooks.
Slings made by other manufacturers
Guldmann shall not be liable for faults or accidents that may occur as a
result of using lifting slings made by other manufacturers.
If there is any doubt about the selection or use of a lifting sling,
please contact your supplier.
Guldmann shall not be liable for faults or accidents due to incorrect use of the
lifting sling, or for reasons of inadequate attention on the part of the healthcare
professional or user.
Attaching the lifting sling to the Cross hanger
Place the straps from the lifting sling on the hooks on the lifting hanger. Start
with the uppermost set of straps (from the back) and then take the lowest set
of straps (from the legs). Refer to section 2.14 Cross Hanger with Connecting
Bar.
Attaching the lifting sheet to Horizontal lifter, foldable
Read the instructions in the user manual for the Horizontal lifter.
Important!
For further information, please refer to the user manual for the lifting sling in
question.
Only people who have received competent instruction regarding the use of
lifting equipment and tting of slings should use the hoist.
Plan the move. Avoid leaving the user in the lifting sling unattended.
Working with the GH3 Twin
The GH3 Twin runs easily in the rail system and does not have any special
requirements for space or power in connection with moving. Attention can
thus be fully focused on the users functional level and the healthcare
professional technique.
If the hoist is used correctly, the user should only be lifted to the extent that
she/he is clear of the surface and should be moved at this height.
The hoist lifts quickly and powerfully. Before lifting, check that the user is
completely free of his/her surroundings. The user’s head, arms, hands and
feet must not be in danger of becoming trapped. Be careful with any tubes
and wires that are attached to the user. The user should not hold the lifting
strap during the moving procedure as there is a risk of crushing between
the strap’s hook and the hoist. Check that the hand control and hand control
cable is free of hanger, user and other object before the hoist is activated
up or down moved.
