KREMLIN REXSON - 1 - N° : 578.004.120-UK-1403
1. OPERATING PRINCIPLE
The pump (A) consists of :
an alternating air motor (B),
an hydraulic section (C) mechanically coupled to the air motor (B).
The air motor is supplied with compressed air by means of the regulator (D) (pantone 382 colour knob or
red knob). The pressure is read on the gauge (E).
During its alternating movement, the air motor drives the piston of the hydraulic section (C). The fluid is
drawn in (L) and forced under pressure in (N). Due to its design, this pressure is always the one read on
the gauge (E) x pump ratio.
The spray air pressure of the gun is adjusted by means of the regulator (black or grey knob) (F) and the
pressure can be read on the gauge (G).
To adjust the fluid flow rate, turn the pantone 382 colour knob or red knob (D) - (Gauge E).
To adjust the spray air, turn the black knob or grey knob (F) - (Gauge G).

2. START-UP
Protective clothing (gloves, protective masks, glasses, hearing
protective earplug, protective clothing) shoul be worn to comply
with the recommendations.
The working area must be correctly ventilated.

KREMLIN REXSON - 3 - N° : 578.004.120-UK-1403
Guards (air motor cover, coupling shields, housings …) have been designed for
safe use of the equipment.
The manufacturer will not be held responsible for bodily injury or failure and / or
damage to property due to removal or partial removal of the guards
Start up procedure :
1 - Ground the pump.
2 - If the pump is an Intensive™one, fill the wetting cup (S) with T lubricant (P) or with an
appropriate cleaning solvent.
3 - Unscrew the air regulators (D and F).
4 - Interconnect the equipment with the air pressure network (clean and dry air - P < 6 bar / 87 psi).
Install a water drop, model 3/8 if it is necessary.
5 - Connect all the hoses (air hose and fluid hose) as well as the gun (O).
6 - Remove the gun air cap by unscrewing the cap ring and nozzle (only in case of an Airmix® gun).
FLUSHING WITH SOLVENT
7 - Immerse suction rod (L) into material container.
8 - Open pump air pressure valve (H).
9 - Point the spray gun, not supplied with air, towards the material container and press the trigger.
10 - Increase gradually the air regulator (D) so that the pump runs slowly (Pressure between 0.5 and
1 bar / 7.25 to 14.5 psi). When material flows out regularly, release the trigger.
PRIMING WITH MATERIAL
11 - Remove suction rod (L) from material container and immerse it in a solvent-filled container (take
all appropriate precautions in the presence of flammable solvents).
12 - Point the spray gun, not supplied with air, towards the material container and trigger the gun until
the material flows out regularly.
WORK
13 - Reinstall the ring, the aircap and the nozzle (only in case of an Airmix® gun) on gun.
14 - Adjust air regulator (D) to get the appropriate material pressure and flow rate.
15 - Gradually open air regulator (F) to adjust spraying air to obtain the required spray pattern.
2-2 PUMP SUPPLIED IN GRAVITY
CAUTION: The pumps can be supplied in gravity but not in filling.
Interconnect the pump fluid inlet with the gravity cup supply hose and start up the pump as previously
indicated.

3. SHUTDOWN AT THE END OF THE WORK
SHORT DURATION SHUTDOWN
1 - Decrease the material pressure of air regulator (D) until reading 0 bar / 0 psi on gauge (E).
2 - Trigger the gun to depressurize the system.
3 - Unscrew the gun air regulator (F) or disconnect the gun air inlet.
4 - Remove the gun air cap and the nozzle (only in case of an Airmix® gun) of the spray gun and
soak it into solvent.
LONG DURATION SHUTDOWN
1 - Decrease the material pressure of air regulator (D) until reading 1 bar / 14.503 psi on gauge (E).
2 - Unscrew the gun air regulator (F) or disconnect the gun air inlet.
3 - Remove the gun air cap and the nozzle (only in case of an Airmix® gun) from the spray gun and
soak it into solvent.
4 - Remove the suction rod from the material container and immerse it in a solvent-filled container.
Take all the appropriate precautions in the presence of flammable solvents.
5 - Point the gun towards the container and trigger the gun. When the solvent flows out, point the
gun towards the recovery container.
6 - When the solvent flows out clean, release the gun trigger.
Nota : If the pump is an Intensive™one, release the spray gun trigger when the pump
piston is in a low position. To prevent from damaging the seals when starting
once again the pump, the piston must be immersed into solvent.
7 - Fully unscrew the air regulator (D) and shut off the compressed air valve (valve H).
8 - Trigger the spray gun to decompress the hoses. Therefore, the pump and the hose remain filled
with solvent at the atmospheric pressure.
4. SAFETY DEVICE
Guards (air motor cover, coupling shields, housings …) have been designed for
safe use of the equipment.
The manufacturer will not be held responsible for bodily injury or failure and / or
damage to property due to removal or partial removal of the guards
AIRMIXpump : A relief-valve (setting : 6.5 bar / 94 psi) is fitted on the pump air motor - thus protecting
this one from an overpressure which could damage it.
