Operating with DYNASET HPW dust high pressure suppression system, user has to conform to all safety 
regulations concerning pressurized equipment. Hydraulic circuit has a highpressure over 220 bar. 

EQUIPMENT TECHNICAL CONDITION HAS TO PAID SPECIAL ATTENTION TO.  

In order to avoid accidents all operators and maintenance personnel must act in compliance with the laws, 
regulations and recommendations the high pressure hydraulics, electricity and work safety issued by local 
authorities. 

EXTERME CLEANLINESS MUST BE MAINTAINED WHEN CARRYING OUT ANY DISSASSEMBLING OR 
REPAIR OF HPW UNIT AND HYDRAULIC SYSTEM. THIS IS CRUCIAL TO ENSURE SAFE, RELIABLE AND 
LONG-LIFE OPERATION OF THE EQUIPMENT.

The pressure in hydraulic fluid circuit is considerably high and hydraulic system has to maintain regularly. 
Especially couplings, valves and hoses have to be tight and clean as well as kept under constant observation. 
Check and fix possible leakages of pressure and hot blowouts immediately avoiding user and bystander injuries.
 
In order to exclude possible accidents, it is not allowed to clean or inspect HPW unit when hydraulic fluid circuit 
is pressurized. Prior to any cleaning, inspection and service hydraulic system of your carrier machine must be 
stopped and all hydraulic fluid circuits depressurized.

Wear appropriate clothing and safety equipment such as goggles, ear and eye protection, safety shoes at all 
times when operating with the HPW dust high pressure suppression system. Beware of warm oily machinery 
parts.   

Operators and maintenance personnel must always comply with local safety regulations and precautions in order 
to close out the possibility of damages and accidents. 

All installation and service hydraulic and electric equipment must be performing experienced personnel only. 

Preventing freezing nozzles, water circuit and pipeline. Draining and air flushing have to perform before ambient 
temperature reaches 0°C (32°F) or lower.
