Acme PoliSpray 3

Description

PoliSpray 3 is a high-pressure spray gun, designed for the application of abrasive

compounds.

Characteristics:

 High exit velocity to overcome the turbulence created by fast rotating buffs

by means of the OW-Head

 Precise volume metering due to the fast acting exit valve by means of OW-

Head

 Precise volume metering of each compound shot

 Optimized maintenance with interchangeable One-Way Spray Head (OW)

 Fast and easy nozzle replacement and air bleeding

 Optional remote spray head with flexible extension

 Ready for use with electronic controls

Caution: Pay close attention to the safety information on the last page!

Installation

The gun body has a through-hole Ø 12 mm for mounting.

A quick-connect air coupler (94) requiring a pneumatic hose Ø 8/6 mm is attached.

3/2-way valve is recommended. Normally closed when de-energized.

 Dead closed by electromagnetic manipulation

 Opening time at least 0.5 seconds

 Delay time at least 1.5 second

The valve should be located as near to the spray gun as possible.

The compound connection (15) requires a hose with an inside diameter of 12 mm.

Start-up

The spray gun timers are to be set accordingly per process requirements. Gun

opening (firing side of cycle) at 0.5 seconds and delay to be no less than 1.5

seconds.

Install the necessary nozzle into the spray head (44) for required spray coverage.

Open the stop-cock (13) for de-aeration, put a screwdriver into the gap between

nozzle nut and spray head; pry the nozzle nut forward until compound discharges in

a continuous flow without interruptions of air.

Manually fire the gun by using the manual switch on pneumatic solenoid.

DO NOT FIRE THE GUN AT ANYTHING OTHER THEN THE MEDIA OR THE PART TO

BE FINISHED. HIGH PRESSURE DISCHARGE CAN CAUSE SERIOUS INJURY IF

POINTED AND FIRED AT A PERSON.

Adjust the compound volume with knurled knob (26) by turning clockwise for less

volume and counterclockwise for increase volume.

Tips for Troubleshooting

Air in the Spray gun

 De-aerate the gun (see – “start-up”) until compound flows without

interruption of air

Compound does not discharge from gun

 Tip is blocked, remove tip and clean or replace it

 Check valve (17) for blockage

o Examine function of check valve:

 Fill gun body with compound

 Lock stop-cock (13)

 Actuate pneumatic valve

o If compound emerges, check valve (17) is broken, clean or replace

 Check air pressure, does it meet required minimum

o Increase to minimum required pressure (72 psi – 5 bar) or greater

 Pneumatic piston assembly does not retract

o Pneumatic cylinder (35) is dirty, open and clean

 Compound connection clogs

o De-aeration (see "start-up"), if no compound flows, check the hose

connection for blockage and clean as required

 Compound pressure to low

o De-aeration (see “start-up”), if little or no compound discharges,

increase line pressure by adjusting pump or pressure pot settings

 OW-Head Failure

o If the OW head cannot be de-aerated, replace the head

 OW-Head leaks

o Leaks from nozzle

o Compound emerges from the bleed bores on OW-Head

 Replace OW-Head

 Compound leaks from bleed holes in main body (28)

o Replacement of plunger (36) and cup seal (9) are required

(replacement of compression spring (37) should also be done at this

time)

 When dismounting and cleaning the spray gun, it is necessary to use the

drawing with parts list.

Safety

The following safety recommendations should be followed when doing any work

on the spray gun:

 Never point the spray gun at other personnel

 Before any repair or maintenance work may be carried out, spray gun must

be disconnected from compressed air and pressure must be released

 Always wear protective glasses

 Close compound supply stopcock

 Before start-up and after each repair or maintenance work, all nuts, bolts and

connections should be reviewed to confirm that all are tight and properly

installed

 Pay attention to the warnings and advices of the compound, buff and

equipment manufacturer

 Do not use aggressive cleaners or boiling water to clean gun or parts.

Nozzles can be cleaned with compressed air or warm water and compressed

air. Exterior of gun can be cleaned with a damp cloth or fiber brush.

Changes in the interest of improvements and technical progress are reserved.

Maintenance

When disassembling the gun for maintenance, it is important to keep all parts that are to

be reused clean. During the reassembly on the cup seal, plunger and compression

spring, it is important to use grease during this process. A light oil should be used to

coat the cylinder wall (35) and flat seal (20).

Spare Parts List

These parts are wear items and should be kept in stock at all times.
