1 About this manual
This manual contains information which is necessary for the safe use of the LUC+125
(FlexxPump 125), version 24 V-DC (impulse-controlled), hereinafter referred to as lubricator.
If this manual is supplied with amendment sheets (e.g. for special applications), then the
information in the amendment is valid. Contradictory specifications in this manual are therefore
void.
The user should contact WITTENSTEIN alpha GmbH with any questions about special
applications. The actual operator must guarantee and ensure that this manual including any
amendments are read and understood by all persons assigned to install, operate, or maintain the
lubricator. For this reason, keep this manual in a suitable and ideally accessible location near the
lubricator.
Inform colleagues who work in the area around the machine about the safety instructions so that
no one sustains injuries.
The original was written in German, all other language versions are translations of the original
manual.
1.1 Information symbols and cross references
The following information symbols are used:
•Indicates an action to be performed
ÜIndicates the results of an action
iProvides additional handling information
A cross reference refers to the chapter number and the header of the target section (e.g.
2.3 "Intended use").
A cross reference to a table refers to the table number (e.g. Table "Tbl - 1").
1.2 Scope of delivery
•Check the completeness of the delivery against the delivery note.
iImmediately notify the carrier, the insurance company, or WITTENSTEIN alpha GmbH in
writing of any missing parts or damage.
2 Safety
This manual, especially the safety instructions and the rules and regulations valid for the
operating site, must be observed by all persons working with the lubricator. General legal rules
and regulations as well as applicable rules and regulations on prevention of accidents [e.g.
personal protective equipment (PPE)] and environmental protection must be observed.
2.1 EC/EU Directive
In scope of the EC/EU Directive, commissioning (recommissioning) of a machine at which the
lubricator was installed and/or attached is prohibited until it is verified that the machine complies
with all provisions of the applicable regulation.
An EC/EU declaration of conformity for this lubricator can be found in the appendix (see
chapter 9.1 "EC/EU declaration of conformity").
2.2 Personnel
Only technicians who have read and understood this operating manual may perform work on the
lubricator. Local and/or company regulations apply accordingly.

en-4 1000088472 Revision: 01
2.3 Intended use
For the intended use of the lubricator, the following points must be observed:
- The lubricator is approved only for industrial applications.
- The lubricator may only be put into operation according to the technical specifications (see
chapter 3.7 "Technical data").
- Unauthorized modifications to the lubricator are not permitted.
- Read and observe the operating manual.
- During operation of the lubricator, regular visual inspections must be carried out at the
lubricator itself as well as the lubrication point. Any irregularities and their cause must be
corrected immediately.
- The cartridge must not be refilled.
- The lubricator must not be opened or dismantled.
- Only lubricants which are approved by WITTENSTEIN alpha GmbH may be used.
- Applicable rules and regulations on occupational safety, prevention of accidents and
environmental protection must be observed.
- Any works or tasks with or at the lubricator may only be carried out with authorization (see
chapter 2.2 "Personnel").
Any use other than the previously described intended use or non-compliance with one of the
points specified above is regarded misuse. In this case no liability or warranty claims will be
assumed.
2.4 Reasonably foreseeable misuse
Any usage of the lubricator that exceeds the maximum permitted technical data is considered
misuse and is therefore prohibited.
2.5 Guarantee and liability
Any guarantee and liability claims are excluded for personal injury and/or material damage in
case of:
- Ignoring the information on transport and storage;
- Misuse;
- Improper or not carried out maintenance and repair;
- Incorrect assembly / disassembly or incorrect operation;
- Operation of the lubricator when safety devices and equipment are defective;
- Operation of the lubricator without lubricant;
- Operation of the lubricator with non-approved lubricant;
- Operation of a heavily contaminated lubricator;
- Modifications or changes without written approval by WITTENSTEIN alpha GmbH;
- Opening and/or partly or complete dismantling of the lubricator.

2.6 General safety instructions
The operation of the lubricator involves remaining risks even when adhering to the intended use.
Defective or faulty electrical connections or unapproved, current-carrying components can
cause serious injuries and even death.
•Have all electrical connection work performed by qualified technicians only.
•Immediately replace damaged cords or plugs.
Loose or overtightened screw connections can cause damage to the lubricator:
•Mount and check all screw connections according to the specified admissible tightening
torques. Use a calibrated torque wrench.
Lubricants are flammable, can cause skin irritation, and can contaminate soil and water:
•In case of fire, do not use a jet of water to extinguish.
•In case of fire, only use suitable extinguishing agents such as powder, foam or carbon
dioxide.
•Always observe the applicable safety instructions by the lubricant manufacturer on the safety
data sheet of the used lubricant.
•Use protective gloves to avoid direct skin contact with lubricants.
•Use and dispose of lubricants properly.
2.7 Structure of warning instructions
Warning instructions are situation-specific. They will
be precisely where tasks are d
escribed in which
dangers can arise.
The warning instructions in this manual are
designed according to the following pattern:
A
= safety symbol
B
= signal word
C
= Type and consequence of the danger
D
= Avoiding the danger
2.7.1 Safety symbols

3 Description of the lubricator
The lubricator is designed as a highly compact double piston pump for grease as lubricant. The
two pistons run force-controlled and in opposing directions. They are both connected to the same
outlet. The outlet is secured by an integrated check valve. At each dispensing cycle , approx.
0.15 cm³ of lubricant are dispensed. Multiple subsequent dispensing processes can be set.
The lubricator must be integrated in an external control system (e.g. PLC). The lubricator features
an electrical interface for control. By means of output signals, the lubricator also enables remote
monitoring for querying of the status and any potential error messages (e.g. empty cartridge). The
lubricator is controlled via various input signals processed by microelectronics to ensure ideal
supply of lubricants to lubrication points.
The different operating statuses are displayed at the front as well as other additional information
(e.g. errors).
