2. Safety Requirements
2.1. General Safety
The machine is built according to the state of the technology and can be operated safely. However,
this does not mean that the consequences of all operational failures are protected by technical
measures. Dangers can arise from this machine if it is used improperly or incorrectly. However, addi-
tional organisational measures have to be taken into account for certain workflows, such as the re-
moval of residual paint from the gun.
Read and follow the operating instructions for machine as well as the safety instructions be-
fore commissioning.
Always keep the manual available in the immediate vicinity of the machine.
The machine may only be operated by trained personnel. Operators under the age of 18 are
only allowed to operate the machine when under supervision of an expert.

sparks) are not allowed within a radius of 1 metre around the machine. This applies
also e.g. for lighting and fans as well as the associated electrical components.
Depending on the cleaning application, use the required personal protective and chemical re-
sistant protective equipment. The minimum required protective equipment is eye protection
and gloves. Optionally protective clothing and safety shoes are recommended.
Minimal require-
ment:
Optional:
Ensure that clothing (especially footwear) is conductive.
Do not place the protective equipment on the machine.
If clothing has been wetted with solvent / cleaning fluid, smoking is also prohibited outside the
Ex-zone. Take off the contaminated clothing immediately. There is risk of skin irritation, aller-
gies, etc. Persons wearing contaminated clothing must not be exposed to sources of ignition
(e.g. welding). Risk of fire.
In the event of a fire, immediately stop the compressed air supply and close the door of the
machine.
Compliance with country-specific workplace exposure limits legislation according to safety
data sheets must be documented.
The limit values of the country specific air pollution and adherence thereto must be observed.
If the machine is not used, the door must always be closed for safety reasons.
The operator has to ensure that nobody else is in the working area of the machine.
Use only permitted solvents / cleaning fluids (section 3). These must be free of Halogenated
hydrocarbons (CKW, CFC, TRI, PER, etc.).
If water (e.g. with additives) is used as a cleaning fluid, this must not be discharged into the
sewer system.
Pay attention to the safety data sheet of the cleaning fluid.
Do not eat or drink near the machine. Clean your hands before eating any food or drink after
working. Danger of poisoning!
Avoid inhalation of fumes and contact with the solvent / cleaning fluids. Risk of respiratory
tract irritation!
Do not add any other liquids to the cleaning fluid, such as kerosene, gasoline, chlorinated hy-
drocarbons, acids, alkalis, pickling agent or brake cleaner.
Do not overfill the unit with cleaning fluid, as this may lead to an overflow of the barrel.
Immediately collect spilled solvent(s) with suitable binders and dispose them in accordance
with regulations. The water resources legislation must be complied with.
When changing the cleaning fluid, all applicable regulations (e.g. waste water regulations) must
be observed!
It is prohibited to open the pump casing in the machine. The manufacturer is not lia-
ble for any damage and/or secondary/subsequent damage caused by opening the

Cleaning System ud-800 Page 5
2.3. Hazards from Pneumatic Energy
Only specialists with expert knowledge and experience may work on pneumatic machines. When work-
ing on pneumatic systems, these must be disconnected from the air supply and de-pressurised in order
to prevent injury.
2.4. Suggestions for Operating Instructions
Operating instructions are regulations that a company creates for safe working for its employees.
These are binding instructions issued by the company in line with its policy and the law. Employees are
obligated to follow these instructions.
The employer is responsible for creating and publishing workplace related operating procedures e.g.
regarding Occupational Safety and Health Regulations, the Water Resources Legislation and, where
applicable, the Control of Hazardous Substances applicable in the relevant country. These operating
instructions are therefore to be complemented by national regulations on accident prevention and
environmental protection.
Give your employee e.g. the following information:
The hazards involving the handling of contaminated parts and the solvents used, the necessary
protective measures and guidelines, including instructions in case of danger and first aid.
The type and scope of periodic inspection for the safe working condition of the machine.
Environmental Protection.
Safe operation of the pneumatic system.
Clean and safe working environment.
The responsibility for operation must be clearly regulated by the company and must be com-
plied with by all persons designated to operate the machine. Under no circumstances should
unauthorised or untrained persons use the machine.
The operator has to operate the cleaning machine only in perfect condition and has to notify
their supervisor immediately in case of any changes affecting safety and environmental pro-
tection.
Follow all warnings and warning signs.

Cleaning System ud-800 Page 6
3. Approved Cleaning Agents
Only use solvents / cleaning fluids that meet the following specifications:
Highly flammable liquids (category 2, flam. liq. 2):
oGHS/CLP H225, flash point <23°C, boiling point >35°C.
oFormerly according to 67/548/EWG: R11, Hazard symbol „F“.
Flammable liquids (category 3, flam. liq. 3):
oGHS/CLP H226, flash point 23°C - 60°C.
oFormerly according to 67/548/EWG: R10, no Hazard symbol.
Non-combustible, aqueous cleaning agents (neutral or slightly alkaline pH) such as B-TEC H2O
Cleaner for water-soluble paints.
If using flammable cleaning liquids, ensure at least a medium electrical conductivity of the liquid. Usu-
ally solvents are mixtures of liquids with high and low conductivity and therefore are sufficiently con-
ductive. If you have any doubts, ask your supplier.
It’s recommended to use purified water to mix B-TEC H2O-RK cleaner, if tap water is
extremely hard water or contains high quantities of iron.
Ensure that the used cleaning fluid is suitable and does not attack the surface of the
object to be cleaned. Suitability shall be ensured by the operator in preliminary tests.
The manufacturer and / or supplier does not assume any liability for damages caused
by these tests.
Acids are not permitted. Paint strippers or other additives (e.g. brake cleaners etc.)
must not be used in the machine.
Safety data sheets relevant to the products supplied should always be available on the
premises. These will contain the information about the cleaning agents that you are
using.
Never alternate the use of solvents and cleaning fluids (for water-based paints) in the
same machine as this will damage it and void the warranty. Follow the manufacturer’s
instructions at all times. Alternating the two types of cleaning agents can cause gas
build up and explosions!
When changing from solvents to cleaning fluids for water-based paints (or vice-versa)
the paint gun cleaner must be completely cleaned of paint, water and fluid residues.
Recommendation to reduce solvent consumption:
If the machine is connected to a continuously running exhaust system and you’re using
solvent, we recommend the pneumatic exhaust solvent safer to reduce solvent con-
sumption.
See B-TEC catalogue number:
Pneumatic exhaust solvent saver diameter 125 mm art.-no.: 10000348
