2.1. IDENTIFICATION DATA OF THE
MACHINE
In order to ensure proper identification of the
machine, please refer to the serial number
stamped on the invoice and the data
imprinted on the manufacturer's plate bearing
the CE marking symbol attesting to its
conformity to the directives applicable.
The plate includes the following required
information:
●Manufacturer’s name and address
(1)
●CE Marking (2)
●Year of construction (3)
●Type designation (4)
●Serial number (5)
●Motorization number (6)
●Motorization power (7)
●Mass in kg (8)
2.2. INTENDED USE
The double trowel machine "MK8-75” is
designed and manufactured to perform
finishing (troweling) of concrete and asphalt
floors of sheds, car parks, cycle paths,
parking areas, sidewalks, etc. To make this
kind of the machining operations the machine
is equipped with two rotors: One of them is
rotates right and the other rotates left.
The engine and the operator's seat are fixed
to a frame connected to both rotors.
The adjustable seat is located at a very low
height which allows you to create different
advantageous conditions for processing:
●A higher flatness of the floor surface
(thanks to a lowering of the machine´s
centre of gravity).
●An excellent view of the inspection of
the processing.
All steering parts (levers, joints, drive
shaft, reducers) are protected by a tunnel
whose purpose is to prevent the
accumulation over time of cement
deposits that can cause a more rapid
damage to mechanical components.
The machine may only be used by
professional operators.
2.3. PROHIBITED USE
Any use other than what is explicitly stated in
PAR. (§ 2.2) and implemented differently or
contrary to what is stated in this publication
represents a possible misuse. The
manufacturer accepts no responsibility
resulting from improper use which may lead
to personal injury and any system
malfunctions.
IMPROPER USE IS CONSTITUTED BY THE
FOLLOWING 'PROHIBITED’ ACTIVITIES:
-THE MACHINE IS USED IN AN
EXPLOSIVE ENVIRONMENT (THIS
FACILITY IS NOT IN COMPLIANCE WITH
ATEX 2014/34/EU).
-OTHER SYSTEMS AND/OR EQUIPMENT
ARE ADDED EVEN IF THEY ARE NOT
INCLUDED BY THE MANUFACTURER IN
THE EXECUTIVE PROJECT.
-THE MACHINE IS ATTACHED TO POWER
SOURCES OTHER THAN THOSE
SPECIFIED BY THE MANUFACTURER.
-THE MACHINE IS USED FOR A PURPOSE
OTHER THAN THAT INTENDED AND
SHOWN IIN THIS PUBLICATION.

2.5. OPERATOR POSITIONS/
LAYOUT/ OPERATION
AND MAINTENANCE AREA
Tier 1 OPERATOR POSITION
IMPORTANT!
To define the maintenance area
you need to consider about 1.5 m
on all sides of the machine (fig
2.3 on next page).
!
CAUTION
Only one operator is required to
operate the machine.
Tasks and positions are detailed
in PAR. (§) 2.5 of this
publication.
Failure to follow the indications
above represents a possible
MISUSE and relieves the
manufacturer from any liability
arising from incorrect
use/misuse.
The machine must be operated by one
single operator. The latter operates the
machine during the normal work cycle.
While using the machine the operator is in a
sitting position. He/she moves the machine
controls consisting of two steering levers
positioned on the left and right side of the
operator and the accelerator lever. All
controls are operated from a sitting position.
The machine can be started with the operator
seated only (a safety micro switch enables
starting only if the operator is seated). The
adjustments pertaining to processing (blade
tilting adjustment) are performed with the
operator in the working position.
The operator position (figure below) is also
an inspection location from where it is
possible to supervise the proper conduct of
the work cycle.
The 1 tier operator is responsible for carrying
out cleaning after use.
2 Tier OPERATOR (RESELLER-
SPECIALIZED DEALER)
The reseller (expert maintenance technician)
performs maintenance and repair tasks
designed by the manufacturer (compare
chapter 6 of this publication).
He/she always operates with the machine
stopped and power disconnected unless
expressly provided otherwise.
2.6. GENERAL DESCRIPTION
The double trowel machine "MK8-75” is
designed and manufactured to perform
finishing (troweling) of concrete and
asphalt floors of sheds, car parks, cycle
paths, parking areas, sidewalks, etc
The power supply is provided by an
internal combustion engine running on
unleaded petrol.

TYPE OF POWER SUPPLY
IMPORTANT!
For more detailed information about
engine characteristics refer to the
manual of the component that is an
integral part of this publication.
The machine must be powered following
the instructions provided by MBW.
For safe operation read the following
precautions carefully:
●The power supply of the device is
provided by an air-cooled internal
combustion engine running on
unleaded petrol.
●The engines fitted to the machine can
be of different types (see technical
characteristics, p. 15).
●Start the engine by turning the ignition
key in the appropriate panel.
The pull-up starting is also
envisaged.
The fuel consists of unleaded petrol
that reaches the carburetor from the
tank after having been filtered.
Blade rotation in the troweling machine
is transmitted by the engine to a pair of
centrifugal clutches, connected with
two trapezoidal belts to rotor
gearboxes.
2.7. SAFETY DEVICES
Security measures included are
represented by (see figure: 2.2):
1) Seat micro-switch that prevents
starting of the machine until the
operator is seated in the
working position
2) Fixed guard of timing belts
3) Fixed guards for safeguarding
of the blades
4) Illumination devices

2.8. INFORMATION ON RESIDUAL
RISKS
Despite the application, at the design stage,
of the rules contained in the safety
requirements (RESS) as required by current
legislation and despite the adoption of safety
measures, there is a residual risk that cannot
be eliminated. Residual risks are
appropriately reported through the application
of specific SAFETY SIGNS called
PICTOGRAMS located at the dangerous
areas.
The pictograms have different meanings, in
particular:
●HAZARD SIGN: BLACK AND
YELLOW OF TRIANGULAR FORM
