The machine can only be operated when the safety trigger is squeezed.
The machine can only be operated when the safety trigger is squeezed. When the lever is
squeezed, the spray gun opens. The liquid is then pumped to the nozzle. The spray
pressure increases and quickly reaches the selected operating pressure.
When the trigger is released, the trigger gun closes and any further spraying of liquid
from the lance is stopped.
The increase in pressure when the trigger gun is closed causes the unloader valve-
safety valve to open. The pump remains switched on and continues to pump liquid
through the pump at reduced pressure. When the trigger gun is opened, the unloader
valve - safety valve closes and the pump ressumes pressure spraying from the lance
The trigger gun is a safety device. Repairs should only be performed by qualified
persons. Should replacement parts be required, use only components authorized
by the manufacturer
Lance with trigger gun
The unloader valve - safety valve protects the machine from a build p of excess pressure,
and is designed not to permit an excess pressure to be selected for operation. The limit
nut on the handle is sealed with a spray coating
The operating pressure and spray rate can be steplessly adjusted by turning the handle.
Replacements, repairs, new adjustments and sealing should only be performed
by qualified persons.
Unloader valve - safety valve
Environmental, refuse disposal and water protection
regulations must be observed !
Water and Cleaning System
Water can be connected at mains pressure to the high pressure pump or it can
be sucked directly from a storage tank. The water is then forced under pressure
by the high pressure pump to the lance. The high pressure jet is formed by the
nozzle at the end of the lance.
Cleaning and caring agents can be mixed with the water by a high
pressure injector (not with K 3170 TST)

Excerpt from the Guidelines for Liquid Spray Equipment (ZH 1/46) by the Central Office of
the Professional Trade Association.
Inspection:
Liquid spray equipment should be inspected for safe operation by a qualified person
whenever necessary, but no less than every 12 months. The maker’s or supplier’s
instructions must be followed. The inspection intervals may be extended if the equipment
is not in active use.
In Germany, inspections compliant with the (German) Emission Controls Act may be
required for oil and gas-fired equipment, and the owner must arrange for these to be
carried out independently of the main inspection.
The results of inspections must be recorded in writing and presented to the respective
authorities on demand. There is no set form for these records.
The information in the operating instructions are a part of the inspection
