DESCRIPTION OF PERFORMANCE
The CDM 23 WP is impressive for daily use in channel construction sites as a functional, robust,
compact core drill motor. The careful design of the safety clip secures the core drill in the harsh
construction site environment as well as acting as a functional handle for daily transport and simple
mounting on drilling motors.
User-friendly - Three gear levels permit optimum speed selection adapted to the specific core
drill diameter
Fast drill crown collet with integrated spindle protection
Centrally positioned EMERGENCY STOP switch on the control display is quick and easy to
operate even in difficult situations
Provided with an additional heat shield on the exhaust hose in the working area to avoid risk
of being burned
Maximum safety through integrated centrifugal force coupling (2-cycle petrol engine) and
mechanical overload coupling (3-gear transmission)
Water pressure vessel for independent core drilling (optional)
9/33
1.1. Basics of intended use
1.1.1 The warranty obligation of the manufacturer and supplier is voided for improper or non-intended
use. Any change to the machine which is not carried out by the manufacturer is prohibited.
Changes, removal or addition of parts to the machine only with the written approval of the
manufacturer.
1.1.2 The machine is constructed according to the state of the art and recognized technical safety rules.
However, danger to life and limb of the user or third parties, and/or damage to the machine or other
property may still arise from its use.
1.1.3 Only operate the machine in technically faultless condition and for intended use, aware of safety
and danger complying with the operating manual. You should particularly handle malfunctions
which can compromise safety immediately, or have them addressed by experts.
1.1.4 The LISSMAC core drill motor CDM 23 WP is a wet core drill motor and belongs to the device class
for stand-guided core drill equipment. The core drill motor is driven via a petrol motor and is used in
combination with water for drilling round holes in stone, lightly reinforced concrete and composite
materials. The core drill motor may only be used with a core drill stand intended for it, and a
diamond tool (core drilling). Fumes from the petrol motor must be vented away from the user by
means of an exhaust hose.
This machine is intended for use by an experienced construction worker in construction zones. Use
of this machine in a manner not described in the operating manual is considered improper.
Intended use also includes compliance with the operating manual and observance of inspection and
maintenance manual.
1.1.5 Foreseeable misuse / non-intended use:
Drilling without a core drill stand
Drilling without water
Drilling in enclosed spaces
Drilling without exhaust hose or with a defective exhaust hose
Drilling of wood, plastic or metal (except for reinforcement in concrete)
Drilling heavily reinforced concrete
Any constructional changes, which change the safety or the type of design.
1.2. Organizational measures
1.2.1 The operating manual must be easily accessible for each person at the location of use.
1.2.2 All additions to the operating manual, all generally valid legal and otherwise binding regulations for
accident prevention and environmental protection are to be followed and instructed!
Such obligations may also apply, for example, to the handling of hazardous materials or the wearing
of personal protective gear or traffic regulations.
1.2.3 Personnel assigned to activities on the machine must have read and understood the operating
manual, particularly the Safety Instructions chapter, before starting work. In the middle of work it is
too late. This applies notably to personnel who only work occasionally on the machine, e.g. for
changeovers and service.
10/33
1.2.4 At least occasionally, perform checks for safe and hazard awareness work by operators while
following the operating manual!
1.2.5 Use personal protection equipment if necessary or required by regulations!
1.2.6 Observe all safety instructions and danger warnings of the machine and keep them in legible
condition! Replace safety and danger instructions, that are damaged or non-readable any more.
1.2.7 For safety-related changes to the machine or its running behavior, stop the machine immediately
and mark it accordingly. Report the problem to the responsible post/person!
1.2.8 No changes, removal or addition of parts without the written approval of the manufacturer! The
instructions of the tool maker must be followed.

1.3.4 The operator must wear personal safety equipment according to the safety regulations, such as
safety shoes, safety gloves and safety glasses.
1.3.5 Clothing worn at the workplace must be close-fitting so that it cannot be caught by moving parts.
All loose objects must be removed. Head cover or a hairnet must be worn if the user has long hair.
1.3.6 Wear breathing protection (mask) if the air has dust particles. Do not breathe in unfiltered masonry
dust as this can be a health hazard.
1.3.7 Remaining in the working area unnecessarily is prohibited! Personnel who are not working on the
machine, with the exception of spotters, must be directed away from the work area. Block off the
working area, if necessary.
1.3.8 During all movements, operating personnel must ensure that they and other people are not
endangered. All obstacles which may hinder the operation or implementation of the machine at the
location of use must be moved out of the way.
1.3.9 Any personnel training, learning, being instructed, or currently involved in general education may
only work with the machine under the continual supervision of an experienced person!
11/33
1.4. Safety instructions for operation phases
1.4.1. Transport, assembly and installation
1.4.1.1 Transport, assembly and installation on/with the core drill motor may only be carried out when the

relevant recycling containers, so that they can be recycled properly.
In the case of damage, the machine must not be put into operation. Even damaged cable and plugs
represent a safety risk and must not be used. In this case, please contact the manufacturer.
If the machine is not immediately put into operation after unpacking, it must be protected from
moisture and dirt.
1.8.
Environmental protection
Packaging material, cleaning agents, used or residual operating materials, as well as removed
wear parts, such as drive belts or gear oils must be taken to recycling corresponding to the valid
regulations for environmental protection at the place of use.
1.9.
Disposal
