A

WORKING PRINCIPLE

The unit LARIUS K-2 is defined “piston pump”. This pump is used
for high pressure painting without air (from this process derives
the term “airless”).

English

The pump is controlled by an motor coupled with a reduction gear.
A cam shaft and a connecting rod allow to obtain the reciprocating
motion necessary to the working of the “pumping group” diaphram.
The piston movement produces a “depression”.

The product is sucked, pushed towards the pump outlet and then
sent to the gun through the flexible hose. A mechanical device
allows to adjust and control the pressure of the material coming
out of the pump.
A safety valve avoiding overpressure, guarantees the total reliability
of the equipment.

The personnel must be equipped with the necessary

safety clothing.

• The manufacturer will not be responsible for the un­loading operations and transport to the workplace of
the machine.

THE BEHAVIOUR OF THE EMPLOYEES SHALL

STRICTLY COMPLY WITH THE ACCIDENT PREVEN­TION AND ALSO ENVIRONMENTAL REGULATIONS
IN FORCE IN THE COUNTRY WHERE THE PLANT
IS INSTALLED AND USED.

Read carefully and entirely the following in-

structions before using the product. Please
save these instructions in a safe place

The unauthorised tampering/replacement of
one or more parts composing the machine, the
use of accessories, tools, expendable materials
other than those recommended by the manu­facturer can be a danger of accident.

The manufacturer will be relieved from tort and criminal
liability.

has been any damage due to transportation.

In case of damage, call immediately LARIUS and the

Shipping Agent. All the notices about possible damage
or anomalies must arrive timely within 8 days at least
from the date of receipt of the plant through Registered
Letter to the Shipping Agent and to LARIUS.

• The disposal of packaging materials is a customer’s
competence and must be performed in accordance with
the regulations in force in the country where the plant is
installed and used.It is nevertheless sound practice to
recycle packaging materials in an environment-friendly
manner as much as possible.

SAFETY RULES

F

• THE EMPLOYER SHALL TRAIN ITS EMPLOYEES
ABOUT ALL THOSE RISKS STEMMING FROM ACCI­DENTS, ABOUT THE USE OF SAFETY DEVICES FOR
THEIR OWN SAFETY AND ABOUT THE GENERAL
RULES FOR ACCIDENT PREVENTION IN COMPLIAN­CE WITH INTERNATIONAL REGULATIONS AND WITH
THE LAWS OF THE COUNTRY WHERE THE PLANT
IS USED.

• ALWAYS KEEP PROPER BALANCE AVOIDING UNUSUAL
STANCE.

• BEFORE USING THE TOOL, ENSURE THERE ARE NOT
DAMAGED PARTS AND THE MACHINE CAN WORK PRO­PERLY.

• ALWAYS FOLLOW THE INSTRUCTIONS ABOUT SAFETY
AND THE REGULATIONS IN FORCE.

• KEEP THOSE WHO ARE NOT RESPONSIBLE FOR THE
EQUIPMENT OUT OF THE WORK AREA.

• NEVER EXCEED THE MAXIMUM WORKING PRESSURE
INDICATED.

• NEVER POINT THE SPRAY GUN AT YOURSELVES OR AT
OTHER PEOPLE. THE CONTACT WITH THE CASTING CAN
CAUSE SERIOUS INJURIES.

• IN CASE OF INJURIES CAUSED BY THE GUN CASTING,
SEEK IMMEDIATE MEDICAL ADVICE SPECIFYING THE
TYPE OF THE PRODUCT INJECTED. NEVER UNDER­VALUE A WOUND CAUSED BY THE INJECTION OF A
FLUID.

• ALWAYS DISCONNECT THE SUPPLY AND RELEASE THE
PRESSURE IN THE CIRCUIT BEFORE PERFORMING ANY
CHECK OR PART REPLACEMENT OF THE EQUIPMENT.

• NEVER MODIFY ANY PART IN THE EQUIPMENT. CHECK
REGULARLY THE COMPONENTS OF THE SYSTEM.

Electrical safety precautions

• Check the "ON/OFF" switch is on the "OFF" position before
connecting the cable to the mains.

• Never carry a plugged-in equipment.

• Disconnect the equipment before storing it and before per­forming any maintenance operation or replacing of acces­sories.

• THE FLUID CONTAINED IN THE FLEXIBLE HOSE CAN
BE VERY DANGEROUS. HANDLE THE FLEXIBLE HOSE
CAREFULLY. DO NOT PULL THE FLEXIBLE HOSE TO
MOVE THE EQUIPMENT. NEVER USE A DAMAGED OR
A REPAIRED FLEXIBLE HOSE.

The high speed of travel of the product in the
hose can create static electricity through di-

scharges and sparks. It is suggested to earth

the equipment.
The pump is earthed through the earth cable of the supply.
The gun is earthed through the high pressure flexible hose.
All the conductors near the work area must be earthed.

• NEVER SPRAY OVER FLAMMABLE PRODUCTS OR SOL-

VENTS IN CLOSED PLACES.

• NEVER USE THE TOOLING IN PRESENCE OF POTEN-

TIALLY EXPLOSIVE GAS.

Always check the product is compatible with
the materials composing the equipment (pump,
spray gun, flexible hose and accessories) with

which it can come into contact. Never use
paints or solvents containing halogen hydrocarbons (as the
methylene chloride).
If these products come into contact with aluminium parts can
provoke dangerous chemical reactions with risk of corrosion
and explosion.

• Do not carry the equipment neither unplug it by pulling the
electric cable.

Protect the cable from heat, oil and sharp edges.

• When the tool is used outdoors, use only an extension cable
suited for outdoor use and so marked.

Never attempt to tamper with the calibre of
instruments.

• Take care when the pumping rod is moving.

Stop the machine whenever someone is within its vicinity.

• Repairs of the electrical equipment should only be carried
out by skilled personnel, otherwise considerabledanger to
the user may result.

SETTING-UP

CONNECTION OF THE FLEXIBLE HOSE TO THE GUN

• Connect the high pressure flexible hoses to the pump and the
guns tightening the fittings strongly (the use of two wrenches
is suggested).

NEVER use sealants on fittings threads.
It is ADVISED to mount a high pressure manometer at the

pump outlet (see on page "Accessories") to read the product
pressure.

• It is recommended to use the hose provided with the standard
kit.

NEVER use a damaged or a repaired flexible hose.

IF THE PRODUCT TO BE USED IS TOXIC, AVOID INHALATION
AND CONTACT BY USING PROTECTION GLOVES, GOGGLES
AND PROPER FACE SHIELDS

TAKE PROPER SAFETY MEASURES FOR THE PROTECTION

Therefore, wash with diluent before sucking the product.

• Remove the suction pipe and take away the solvent tank.

English

• Lift the suction pipe and dip it into the solvent tank.

• Ensure the gun (G1) is without nozzle.

G1

• Turn the key (G2) of the equipment to the ON (I) position.

• Turn clockwise the pressure control knob (G3) so as the
machine works at idle speed.

ONOFF

G4

G5

• Point the gun at the solvent tank and press the trigger so as
to recover the residual solvent.

• As soon as the pump starts to over-rev turn the key to the

OFF (0) position to switch off the equipment.

Absolutely avoid to spray solvents indoors. In
addition, it is recommended to keep away from
the pump in order to avoid the contact between
the solvent fumes and the electric motor.
