1.1 GLOBAL ASPECTS ABOUT SAFETY
Compliance with the rules and
recommendations contained in this
publication allows safe use ofthemachine and
appropriate action.
1) The best performance and maximum life of
the machine will be obtained from the
proper use of the same. It is, therefore,
necessary to scrupulously observe the
instructions contained in this booklet;
2) Any requests for spare parts must be
accompanied by the type of model and
serial number reported in the spare parts
list or applied on the number plates of the
components themselves;
3) The machine installation must be carried
out in compliance with the safety
regulations in force;
4) Do not remove or tamper with the
protections and safety devices, check
periodically their effectiveness;
5) Strictly adhere to the warnings recalled on
the danger postings (pictograms) and keep
the message readable;
6) Operation and maintenance must be
performed by qualified personnel, trained
and authorized to the tasks foreseen.
Intervention procedures and
responsibilities of operators must be clearly
defined to ensure safe and proper use and
maintenance;
7) Before any maintenance or adjustment
work, all the power supplies must be
disconnected and locked, ensuring that
they are not subject to unintentional start-
ups;
8) The maintenance of the machine carried
out in a manner that does not comply with
the instructions provided, with non-original
spare parts or without written authorization
by the company that performed the
maintenance of the used machine or in
any case in such a way as to jeopardize
its integrity or modify its characteristics,
exempts the company itself from any
liability concerning the safety of persons
and the faulty operation of the machine.

2.5 OPERATOR POSITIONS/LAY-OUT/USE
AND MAINTENANCE AREA/
1st level OPERATOR POSITION
A single operator must work with the
machine.
He drives the machine by acting on the
handlebar to move it according to the
needs of the processing and performs
some ordinary maintenance activities.
During use the operator position is adjacent to
the handlebar of the machine.
The operator position is also considered an
inspection position from which it is possible
to oversee the smooth running of the working
cycle.
The first level operator is also responsible for
carrying out cleaning operations at the end of
use.
2nd level OPERATOR (RETAILER-
SPECIALIZED WORKSHOP)
The retailer (expert maintenance
technician) performs maintenance and repair
tasks provided by the manufacturer (compare
Chapter 6 of this publication).
Always intervenes when the machine is
stopped and energy cut.
2.6 GENERAL DESCRIPTION
The Trowel "Moskito" is dedicated to finishing
of the edges on concrete floors, resin floors
and substrates. Operation is manual.
The power supply is supplied by a an
unleaded gasoline fuelled engine.

next page).
!
ATTENTION
Only one operator is required to
drive the machine.
Tasks and positions are detailed
in para (§) 2.5 of this publication.
Failure to follow the indications
above conFIG.s the hypothesis of
misuse and releases the
manufacturer from any liability
arising from misuse/abuse.

2.7 TYPES OF POWER SUPPLY
The machine must be powered by following
the instructions given by MBW.
For safe operation read the following
information carefully:
•The device is powered byan air-cooled
petrol engine powered by unleaded
petrol..
•The engines fitted to the machine can
be of different types (see technical
characteristics, p. 14).
•The engine is started by pulling.
•The fuel consists of lead-unleaded
petrol that from the tank reaches the
carburetor after being filtered.
•The rotation motion of the trowel
blades is transmitted by the engine to
a centrifugal clutch, connected with a
trapezoidal belt to the rotor gearbox.
2.8 SAFETY MEASURES
The safety measures included are:
1) Stop levers (maintained action
commands)
2) Timing belt fixed guard
3) Fixed guards of blades segregation.
Horizontal distance between
handlebar and dangerous bodies
equal to 900 mm.
2.9 INFORMATION ON RESIDUAL RISKS
Despite the application, in the design phase,
of the precepts contained in the safety
requirements (RESS) provided for by current
legislation and despite the activity of adopting
safety measures, there is a residual risk that
cannot be eliminated. Residual risks are
appropriately reported through the application
of specific SAFETY SIGNALS called
PICTOGRAMS located at the danger zones.
The pictograms have different informative
values, namely:
•WARNING SIGN: BLACK AND
YELLOW TRIANGLE
•PROHIBITION SIGNS: WHITE AND
RED CIRCLE
•SIGNS OF OBLIGATION: BLUE AND
WHITE
RESIDUAL RISKS ARE SUMMARIZED IN
THE TABLES ON THE FOLLOWING PAGES
(from page 17 to page 21).
IMPORTANT!
For more detailed information about the
characteristics of engine refer to the
manual of the component that is an
integral part of this publication.

It is forbidden to start the machine
without connecting the float disc to the
vanes as indicated in the user manual.
There is a risk of entanglement, pro-
hibited use of loose or fluttering cloth-
ing (are banned scarves, scarves, or
ties non-adherent clothing).
In case you need to replace the disc,
you need to use protective gloves as
some components (blades), if worn
out, could be sharp.
In case it is necessary to lift the ma-
chine (operation allowed only through
the lifting hook supplied), first remove
the trowel disk in as it could inadvert-
ently disengage.
It is mandatory to use the devices of
individual protection required for the
employee (safety shoes, gloves,
mask).
Before starting maintenance activities,
carefully read the instructions in the
user manual.
It is prohibited to circumvent the safety
devices implemented on the machine.
