1 Foreword
1.1 Target
To serve our customers faster and more efficient it is important to achieve a general
standard of technical know how with our partners in the market.
Therefore we developed a Technical Training concept which is based on TASKI spares.
The concept consists of a Technical Manual and a Technical Training.
These two tools will be produced for each newly launched machine with a certain com-
plexity. The Technical Manual will be available as PDF file and can be downloaded from
TASKI spares. The Technical Training documentation will be distributed after having at-
tended the technical training.
1.2 Technical Training
The Technical Training is addressed as reference book for the technical training sessions
and will be distributed to the floor care responsible and/or to the technical training re-
sponsible after attending a training session provided by GTS (max. 2 persons per coun-
try).
The intension is, that after this session, a technical trainer is able to perform technical
training for their local technical staff and in this way to transfer the knowledge to all ser-
vice technicians.
The Technical Training is not intended as manual for the service technicians and will be
distributed only to the training responsible of each country.
1.3 Technical Manual
The Technical Manual is addressed to the service technicians and should be translated
and distributed after a technical training.
It contains a summary of procedures, hints and suggestions etc. which are helpful and

essential for the daily business. The Technical Manual can be downloaded from TASKI
spares/documents.
1.4 Summary
We are convinced that the Technical Manual concept together with the Technical Training
are powerful tools, which will help our service organisations to achieve a higher level of
quality in repairs and customer satisfaction.
If you have any comments or questions do not hesitate to contact your country respon-
sible.
Sincerely yours
GTS Team

2.1 Health & Safety
Scrubber dryers may be powered by mains electricity or batteries. There are risks asso-
ciated with both, which call for proper precautions, such as the provision of good venti-
lation and the elimination of risk of ignition.
All work, carried out on such machines, should only be performed by trained personnel
in accordance with local regulations.
Before working on such a machine, isolate it from any electrical power source.
Always wear the required personal protective equipment (including gloves and goggles)
that must be worn when potentially exposed to any hazardous material and when carry-
ing out hazardous tasks.
Note that parts may be contaminated with chemical product. If possible flush hoses out
with fresh water prior to carrying out any maintenance. For information on chemical
products that are used in this machine, please carefully read the product label and Ma-
terial Safety Data Sheet (MSDS).
Empty water tanks prior to carrying out any maintenance. Ensure contaminated water is
emptied into an approved drain. Avoid pollution.
2.2 ESD
Static electricity is electricity at rest or the accumulation of electric charge, as opposed
to an electric current which is the movement of electricity. The flow or movement of peo-
ple and/or materials in and through the environment causes separation of electrons and
therefore static electricity. A familiar example of static electricity is when a person walks
across a carpeted floor. Static electricity/electrostatic charge is generated simply by the
contact and separation of the soles of that individual's shoes from the carpeted floor.
Electrostatic Discharge (ESD) occurs when the electrostatic charge is transferred from a
material that carries the charge to an electrostatic sensitive device. In the example above,
this electrostatic discharge is the „shock“ felt after walking across the carpeted floor and
then touching a door knob. It is this electrostatic discharge, which comes in varying de-

grees, that can be most damaging to electronic devices.
Relatively dry air or low humidity and even insulating floors facilitates the formation of
static charges. The effect of static charges on machines or operators can be reduced by
using for example an „Anti-Static“ resources, like anti-static strap on the machine, or
floor treatment and suitable clothing as well as shoes.
Static electricity, is a natural phenomenon and consequently electrostatic discharge is
the primary cause of countless problems affecting industry, business and personal life.
These problems can be as simple as the shock resulting from walking across a carpet; as
costly as the destruction of sensitive electronic components.
Almost any material can generate static electricity. The ability to store or unload the
charge depends on the type of material.
Static discharge can damage devices, this can result in immediate product failure or in a
latent failure. Latent failures can go undetected for a period of time, the results are prod-
uct failure in the field.
Electrostatic fields are associated with charged objects.
The degree of severity of ESD events depends on the type of discharge which occurs. The
three most common ESD charge transfers are:
• from an external object to the device.
• from a device to another object.
• resulting from electrostatic fields.
Please do not store electronics without ESD bags at any time.

3.1.3 Consumable supplies
If you have to remove cable ties then position the new ones at the
original place.
If you have to remove self locking nuts, you should replace them by
new ones.
If you have to remove retaining washers, observe the condition and
replaced them with new ones, if they do not fit tight anymore.
Use adhesive locking when ever mentioned in the Technical Manual or
TASKI spares.
Use ball bearing grease when ever mentioned in the Technical Manuel
and TASKI spares.
3.1.4 Direction description
On the „RH“ always means on the right hand side of the machine in
working direction (when you are standing behind the machine).
On the „LH“ always means on the left hand side of the machine in
working direction (when you are standing behind the machine).
3.1.5 Power source
Depending on the work it might be required to remove the power
source (mains/batteries) from the machine.
The in here mentioned sequences (mechanical and electrical) are
based on the assumption that the power source (mains/batteries)
were removed from the machine before.
