OPERATING MANUAL
Preface These operating instructions are intended to make it easier to get to know the machine and to use it for its
intended purpose.
The operating manual contains important information on how to operate the machine safely, properly and
economically. Observing them helps to avoid hazards, prevent repair costs and downtime, and increase the
reliability and service life of the machine.
The operating manual should be supplemented by instructions based on existing national accident
prevention and environmental protection provisions.
The operating manual must be constantly available at the place of use of the machine.
The operating manual must be read and applied by every person who is commissioned with work on the
machine e.g.:
Operation, including setup, troubleshooting in the workflow, removal of
production waste, maintenance, disposal of operating and auxiliary materials.
Maintenance (servicing, inspection, repair) and/or
Transportation
.
In addition to the operating manual and the binding accident prevention regulations applicable in the
country and location of use, the recognized professional regulations for safe and correct working practice
must also be observed.
Related documents In addition to this operating manual, further documentations from the respective manufacturer of individual
components of the machine are available:
Instruction manual chain hoist
Changes and reservations We strive to keep this operating manual correct and up to date. In order to maintain our technological
advance, it may be necessary to make changes to the product and its operation without advance notice. We
assume no liability for disruptions, downtime and damages that thereby result.

1.1. Principle of intended use
The manufacturer and supplier assume no liability for inappropriate use or usage other than the
intended use.
The mini crane is built according to the state of the art and the recognized safety rules. Nevertheless,
danger to life and limb of the user or third parties or impairment of the machine and other material
assets may occur during use.
Only use the mini crane when it is in perfect technical condition and in accordance with its intended
use and in a safety-conscious and hazard-conscious manner. Use in compliance with the operating
instructions!
In particular, faults that can impair safety must be eliminated immediately (or have them eliminated)!
Intended use The LISSMAC mini crane LMK 220 belongs to the equipment class of hand-operated manipulators and
is used exclusively for moving individual masonry units in conjunction with a LISSMAC block gripper.
In the case of hand-guided shifting, the control unit is permanently mounted on the stone gripper and
may only be operated by one operator. The maximum load capacity of 220 kg is preset by the chain
hoist. The device may only be operated up to wind force 7 (15 m/sec).
Any use other than this will be deemed unintended.
Intended use also includes observing the operating instructions and complying with the inspection and
maintenance information
Non-intended use Foreseeable misuse / non-intended use:
Use of other stone grippers or any other slinging means which are not approved by LISSMAC.
Using the LMK 220 mini crane when the control unit is not permanently mounted on the stone
gripper
Lifting persons
Lifting of building materials other than individual masonry blocks with the stone grippers
Lifting of anchored parts e.g. pulling poles out of the ground

1.2. Organizational measures
Always keep the operating instructions at the place of use of the crane within easy reach of any
person.
Observe and instruct supplements to the operating instructions such as generally applicable legal and
other binding regulations for accident prevention and environmental protection.
Such obligations may also relate, for example, to the handling of hazardous substances or the wearing
of personal protective equipment or road traffic regulations.
The personnel assigned to work on the mini crane must have read and understood the operating
instructions before starting work, especially the chapter on safety instructions. During the work
operation it is too late. This applies in particular to personnel only occasionally working on the mini
crane, e.g. during setup and maintenance.
Regularly check that personnel are aware of safety and hazards while working according to the
operating instructions.
Use required personal protective equipment.
Observe all safety and danger instructions on the mini crane.
Keep all safety and danger notices on the mini crane complete and in legible condition.
In the event of safety-relevant changes to the mini crane or its operating behavior, shut down the mini
crane immediately and label it accordingly. Report malfunction to the responsible office/person.
Do not make any modifications to the mini crane without the written consent of the manufacturer.
Only use tested original spare parts from the manufacturer.
Observe the prescribed intervals for inspections or those specified in the operating instructions. An
annual inspection by an expert (TÜV or manufacturer) is mandatory.
Before testing, the mini crane must be cleaned thoroughly.
Annual inspections must be carried out with the mini crane, these must be recorded in writing in these
operating instructions.
The mains plug must be removed from the power supply before starting any maintenance or repair
work.
1.3. Selection and qualification of personnel; basic duties
Only persons who have reached the age of 18 may be employed to operate the mini crane
independently. All persons must be instructed in the operation of the mini crane and must be
expressly authorized by the contractor to operate the crane.
The operator must wear personal protection equipment such as safety shoes and construction helmet
that comply with local safety regulations.
Unnecessary stay on or in the movement area of the mini crane is prohibited. Direct persons who are
not working with the mini crane out of the work area. If necessary, cordon off the work area.
During all movements of the mini crane, the operator must ensure that he does not endanger himself
or other persons.
