Cleaning Device PWA 1000i Page 8
3.4 Hazards from pneumatic energy
Only specialists with special knowledge and experience may work on pneumatic equipment. When
working on pneumatic aggregates or elements, these must be made pressureless beforehand in
order to prevent injury!
Prevent disconnected not pressurized compressed air supply lines from restarting. If the systems
leaks, disconnect it from air supply and then tighten the screwed connections.
3.5 Excitation for operating instructions
Operating instructions are regulations that a company creates for safe operation. These are binding
instructions issued by the entrepreneur within the framework of his management right. The
employees are obligated to follow these instructions.
The general obligation of the entrepreneur to create and publish operating instructions is laid down
in the Occupational Safety and Health Ordinance (BetrSichV), the water resources law (WHG) and,
where applicable, the Ordinance on Hazardous Substances (GefStoffV). The present operating
instructions are therefore to be complemented by national regulations on accident prevention (UVV)
and environmental protection.
Give information to the employee about:
• the dangers involving the handling of contaminated parts and the solvents used, the necessary
protective measures and behavior, including instructions in case of danger and first aid.
• Type and scope of periodic inspection for safe working condition of the device
• Environmental Protection
• Safe handling of the pneumatic system
• By means of instructions and controls, the user has to ensure cleanliness and clarity at the
workplace of the device.
• The responsibility for operation must be clearly regulated by the user and must be complied by all
persons, so that no unclear competences occur under the safety aspect.
• The operator has to undertake to operate the cleaning device only in perfect condition and to
immediately notify its supervisor of any changes that affect safety and environmental protection.
• Observe all warnings and warning signs.
• The user has to ensure that no unauthorized persons are at the cleaning device.
It is prohibited to open the pump case in cleaning devices!
The manufacturer is not liable for any damage and/or secondary/following damage
caused by opening the pump case on purpose or negligent opening.
If you got any problems with your pump device, please contact your distributor or the
MARX support.

Cleaning Device PWA 1000i Page 9
4. Approved Cleaning Agents
Only use solvents / cleaning media that meet the following specifications:
• Highly flammable liquids, hazard symbol „F“ / R 11 flashpoint < 1°C such as lacquer solvents,
but excluding all "extremely flammable" fluids with a flash point under 1°C.
GHS/CLP H 5 flashpoint < 3°C, boiling point > 35°C.
• Flammable liquids, hazard symbol - / R 10, flashpoint 1 – 55°C.
GHS/CLP H 6 flashpoint 3 – 60°C.
• Non-flammable, aqueous cleaning agents (neutral or slightly alkaline pH) such as distilled
water for water-soluble varnishes and paints.
• The machine ud-800 are classified as machine category , group II,
machine type explosion group II B and can be used in zone 1.
See also machine rating plate: II 2 G c II B T6
Acids are not permitted. Paint strippers or other additives (e.g. brake cleaners etc.)
may must not be used in the washing unit.
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 washer must be completely cleaned of paint, water and fluid residues.
Recommendation to reduce solvent consumption:
If the unit shall be connected to a continuously running exhaust when using solvent,
we recommend the pneumatic exhaust damper to reduce solvent consumption.
See catalog no.: 10000348 / ATEX version.
