Notes over the operating instruction:
Lifting systems from Ergoswiss AG are intended for installation in an overall system (e.g. assembly table)
and classified under the category of incomplete machines in accordance with the Machinery Directive
2006/42/EC.
This operating instruction contain information on the commissioning, handling and safety of the lifting sys-
tem and are aimed at the further-user and manufacturer of the entire system. The further-user of this lifting
system is obliged to create an operating manual with all usage information and hazard warnings for the en-
tire system.
The declaration of incorporation is only valid for the Ergoswiss lifting system and not for the overall system
created by the further-user.

2System description
2.1 In general
The basic functionality of a hydraulic lifting system by Ergoswiss AG is the lifting and lowering of work sur-
faces, machine parts, profile systems, etc.
An operative hydraulic lifting System consists of a minimum of following components:
→Lifting element (Table leg Tx, Linear unit Lx, Cylinder Cx) with tubing
→Pump (PA, PB, PF) with Hand crank
The hand crank moves an internal spindle drive inside the pump, which forces the volume of oil from the
pump through the tubing into the lifting elements.
2.2 Intended purpose use
Scope of application
NOT scope of application
→Height adjustment of worktops
→
Height adjustment of machine parts
→
Height adjustment of profile systems
→
… the list is not exhaustive
→Clamping tool
→
Press (or counterhold for press)
→
Passenger transport
→
Security component
→
… the list is not exhaustive
2.2.1 General safety instructions
ATTENTION
The safety instructions must be paid attention to! If the system is operated improperly or not
in accordance with the intended use, there may be a risk to persons and property!
The lifting system may be used if:
→it is located in closed rooms, in a dry and non-explosive environment.
→the ambient temperature is between +10 °C and +40 °C.
→This device can be used by children aged 8 and over and by persons with reduced physical, sensory or
mental abilities or lack of experience and knowledge if they are supervised or have been instructed in
the safe use of the device and the resulting dangers to understand.
The lifting system must not be:
→operated outside of the performance data (max. compressive, bending moment loads).
→subjected to tensile loads (lifting system is a single acting hydraulic system).
→subjected to impulse, impact and impact forces (e.g. setting down loads).
→operated on unstable or sloping ground.
→operated with impermissible or non-designated components.
→operated with damaged components.
→opened, reworked or rebuilt.
→Children must not play with the device. Cleaning and user maintenance shall not be made by children
without supervision.

When installing and operating the lifting system, the intended use of the entire system must be adhered to.
Commissioning is prohibited until the entire system complies with the provisions of the EC Directives
2006/42/EC (Machinery Directive). For this purpose, it is essential to perform a risk analysis, so that possible
residual hazards can be reacted to (e.g. through constructive measures or through instructions in the oper-
ating instructions and/or through safety indication on the system). In the event of improper use, the liability
of Ergoswiss AG and the general operating permit for the lifting system will expire.
2.3 Target group and prior knowledge
Before installing and operating the lifting system, this operating instruction must be read and understood.
The manual must be kept in close proximity to the system for future reference.
This operating instruction addresses the following groups of people:
The manufacturer of the overall system who integrates this lifting system into an overall system and
integrates these operating instructions into the operating instructions for the overall system.
The commissioning personnel who install the lifting system in a workplace, a machine, etc. and put it
into operation. For commissioning basic mechanical and electrical knowledge are required.

NOTE
The lifting system can be subjected to uneven loads as long …
→
the max. load on the single lifting element is not exceeded,
→
the max. bending torque of the lifting element is not exceeded,
→
the entire system is located on sufficient safe ground
… and the entire plant has been constructed in accordance with the provisions of the mechan-
ical equilibrium. Conducting a risk analysis
ATTENTION
High pulse / impact forces due to the discontinuation of loads are not allowed.
(e.g. discontinuation of loads in feed with crane or forklift)

3Mounting instructions
3.1 Mounting instructions Lifting element
NOTE
The hydraulic tubing is to be assembled to the lifting element in accordance with the assembly
instructions. Information on mounting the lifting element can be found in the technical draw-
ings.
3.2 Mounting instructions Pump
NOTE
The lifting element is to be assembled to the pump in accordance with the assembly instruc-
tions. Information on mounting the pump can be found in the technical drawings.
NOTE
To all connections of the pump a lifting element must be connected to, otherwise the pump
will block and the lifting system will be damaged.
3.3 Mounting instructions Lifting system
NOTE
The pump with hand crank is to be assembled to the existing system in accordance with the
assembly instructions. Information on mounting the pump with hand crank and the lifting ele-
ments can be found in the technical drawings.
NOTE
The minimum tubing bending radius is 25 mm. The tubing must be routed in such a way that
it is not exposed to any mechanical stress, no aggressive media (chemicals), no direct sunlight
(UV radiation) and no heat.

4Operation
ATTENTION
Danger of squeezing during height adjustment!
ATTENTION
The entire lifting area of the lifting element must always remain free. The lifting element is
not allowed to hit a stop before it reached its upper and lower block positions. Otherwise air
will be pulled into the system or too much pressure will build up.
4.1 Extending the lifting system
By turning the hand crank clockwise the lifting elements are extended.
Turn the crank until the desired working height is reached.
NOTE
The hand crank may be actuated with a maximum torque of 18 Nm!
The system must not be driven towards the end position with momentum!
4.2 Retracting the lifting system
By turning the hand crank counter-clockwise the lifting elements are retracted.
Turn the crank until the desired working height is reached.
NOTE
The hand crank may be actuated with a maximum torque of 18 Nm!
The system must not be driven towards the end position with momentum!
Max. 18 Nm
Max. 18 Nm

4.3 Folding hand crank – Only with Hand crank foldable!
NOTE
The Hand crank foldable (113.00005) cannot be removed.
This can be folded, for example under a table top.
The crank body can be folded down by pulling the hand crank handle.
After folding back the crank body again, the pump can be operated again.
4.4 Remove hand crank – Only with Hand crank removable!
NOTE
The Hand crank removable (113.00013) cannot be folded down.
This can be pulled completely away from the pump and then attached again.
By pulling on the hand crank, it can be pulled away from the spindle shaft of the pump.
After reconnecting the hand crank, the pump can be operated again.

5Maintenance and disposal
5.1 Maintenance and cleaning
The lifting system is maintenance-free during normal operation resp. when complying with the intended use.
Therefore a service is not required.
5.2 Repairs and spare parts
Repairs must only be conducted by specialists. Only original replacement parts may be used. For all repair
work the system must always be unloaded.
5.3 Disassembly and disposal
The system consists of components that can be fully recycled and thus they are quite safe from an environ-
mental protection perspective.
5.4 Trouble-shooting
ATTENTION
The lifting system must not be opened, reworked or operated by impermissible components.
