FOR WATER-BASED MATERIALS ONLY
WORKING PRINCIPLE
The PEGASO apparatus is an electric pump, used for
spraying wall plaster or synthetic materials for covering
indoor and outdoor walls.
The apparatus is equipped with a 50 litre tank, easy to fill
and funnel-shaped, which makes it easy for the material
to fall into the peristaltic pump.
The pump, easy to maintain, allows for a regular and
constant flow of the product.
On the end of the feed pipe there is a maximum pressure
valve, in order to eliminate choking or occlusions that can
damage the pipe.
When the operator squeezes the trigger on the gun, the
flow and pressure of the pump start, creating a soft flow
of material. When the trigger is released, the flow stops.
The supply of vaporisation air only occurs if the trigger is
squeezed.

•NEVER MODIFY ANY PART IN THE EQUIPMENT. CHECK
REGULARLY THE COMPONENTS OF THE SYSTEM.
REPLACE THE PARTS DAMAGED OR WORN.
•TIGHTEN AND CHECK ALLTHE FITTINGS FOR CONNEC-
TION BETWEEN PUMP, FLEXIBLE HOSE AND SPRAY GUN
BEFORE USING THE EQUIPMENT.
•ALWAYS USE THE FLEXIBLE HOSE SUPPLIED WITH
STANDARD KIT. THE USE OF ANY ACCESSORIES OR
TOOLING OTHER THAN THOSE RECOMMENDED IN
THIS MANUAL, MAY CAUSE DAMAGE OR INJURE THE
OPERATOR.
•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.

• Connectthepressureflexiblehosetothepumpand
the gun tightening the metal clamps.
NEVER use sealants on fittings threads.
The type of materiel you are spraying
will determine the maximum lenght of
hoseyou can use. If you are not achieving
a satisfactory spray pattern or coverage,
try using a shirter lenght of hose.
• Itisrecommendedtousethehoseprovidedwiththe

flexible hose.
CHECK ON POWER SUPPLY
• Check the plant is earthed.
• Check the mains voltage corresponds to the equip-
ment’s rating.
• The supply cable is provided without plug. Use a plug
which guarantees the plant earthing. Only a technician
or a skilled person should perform the connection of
the plug to the electric cable.
Should anyone use an extension cable between the
tooling and the socket, it must have the same cha-
racteristics as the cable supplied (minimum diame-
ter of the wire 2.5 mm2) with a maximum length of
50 mt. Higher lengths and lower diameters can pro-
voke excessive voltage falls and also an anomalous
working of the equipment.
☞PLEASE NOTE :
Check the ON/OFF switch is on the “OFF” position
(0) before connecting the cable to the mains.

PROCEDURE OF DECOMPRESSION
• Afterhavingcarriedoutalltheoperationsdescribedinthechapterconcerningcleaningupafterwork,makesure
that the system is not pressurised.
•Squeeze the trigger and wait for all the material to have come out.
If you suspect that there may be residual pressure in the hoses due to material clogging, loosen the
metal hose clamps very slowly until you feel a decrease in pressure owing to the expulsion of the
material.
MOVING THE SPRAYER
•To move the sprayer backwards or forwards it is necessary to tilt it slightly. This is done by lightly pushing on the
handles with your hands and simultaneously pushing downwards with one of your feet on the footplate.
