6 Operation6.1 Safety recommendations

WARNING!

Danger of explosion due to chemicalreactionsMaterial, halogenated hydrocarbon-basedrinsing agent or cleaning agent can chemi-cally react with aluminum components ofthe product. Chemical reactions cancause explosions. Serious injuries anddeath can be the consequence.– Only use rinsing agents and cleaning

agents that do not contain any halo-genated hydrocarbons.

NOTICE!

Material damage due to dried materialresiduesIf material residues dry in the product, thatcan harm components.– Rinse product immediately after each

use.

6.2 Checks1. Perform the following checks during oper-

ation:Check air connection for correct seatand leaks.Check air car for cleanliness.Check nozzle for cleanliness.

6.3 Selecting air capYou can convert the spray gun for varioususes by swapping the air cap.

Air cap ALThe air cap AL is used for solvent-basedcoating materials (1-component paints and2-component paints) and water-based ones.It is used for application of fillers, basecoatsand topcoats. If used with a hardenednozzle, coating materials with abrasive addi-tives (coating materials containing zinc andaluminum) can be applied.

Air cap ELThe air cap EL is used for solvent-basedcoating materials (1-component paints and2-component paints) and water-based ones,if higher outflow rates are required.

Air cap GLThe air cap GL is used for thick, high vis-cosity coating materials. It is used for appli-cation at a high outflow rate.

7 Cleaning and maintenance7.1 Safety recommendations

WARNING!

Danger of fire and explosionFlammable coating materials and theirdetergents and cleaning agents can causea fire or an explosion.– Ensure that the flashpoint of the fluid is

at least 15 K above the ambient tem-perature.

– Note explosion group of the fluid.– Follow safety data sheets.– Ensure that forced ventilation and fire

protection equipment are in operation.– Do not use sources of ignition and

open light.– Do not smoke.

WARNING!

Risk of injury from unsuitable replace-ment parts in explosive areas.Replacement parts not compliant with thespecifications of the ATEX guidelines cancause explosions in an explosive atmos-phere. Serious injuries and death can bethe consequence.– Use exclusively original replacement

parts.

WARNING!

Danger to health from harmful or irri-tant substancesContact with hazardous liquids or vapors,can result in serious injury or death.– Ensure that the forced ventilation is

operational.– Follow safety data sheets.– Wear specified protective clothing.

WARNING!

Risk of injury due to escaping materialand compressed airEscaping compressed material can causeserious injury.Before carrying out any work:– Disconnect the system, in which the

spray gun is installed, from com-pressed air and material supply.

– Secure the system against reconnec-tion.

– Relieve the lines.

WARNING!

Danger of explosion due to chemicalreactionsMaterial, halogenated hydrocarbon-basedrinsing agent or cleaning agent can chemi-cally react with aluminum components ofthe product. Chemical reactions cancause explosions. Serious injuries anddeath can be the consequence.– Only use rinsing agents and cleaning

agents that do not contain any halo-genated hydrocarbons.

CAUTION!

Risk of injury due to spring tensionThe set screw of the spray gun is underspring tension. If you remove the setscrew, the spring tension could cause theset screw to jump out unexpectedly andcause light injuries.– Remove and install set screw.

Cleaning and maintenance

05/2018EcoGun 116 - MSG00017EN14/44

NOTICE!

Unsuitable cleaning agentsUnsuitable cleaning agents can damagethe product.– Only use cleaning agents approved by

Assembling5. See that the alignment of the

components to be installed is cor-rect.

Push in needle carefully into the housing,until the needle tip comes out in the areaof the trigger.

8. String spring guide (3).

9. String needle gland (2).

10. Tighten gland bolt (1) sensitively.

If there are leakages in opera-tion after you replace the needlegland seal, you have to tightenthe needle gland seal a littlemore.

11. Install needle Ä 8.3.1 “Replace needleand nozzle.”.

9 Disassembly and Disposal9.1 Safety recommendations

WARNING!

Risk of injury due to escaping materialand compressed airEscaping compressed material can causeserious injury.Before carrying out any work:– Disconnect the system, in which the

spray gun is installed, from com-pressed air and material supply.

– Secure the system against reconnec-tion.

– Relieve the lines.

9.2 DisassemblyPersonnel:



1. Rinse the spray gun Ä 6.7 “Rinsing”.

2. Disconnect the compressed air supplyand material feed. Secure against recon-nection.

3. Disconnect all lines.

9.3 Disposal

ENVIRONMENT!

Incorrect disposalImproper waste disposal threatens theenvironment and prevents re-use andrecycling.– Always dispose of components in

accordance with their characteristic.Ä 10.7 “Materials used”

– Collect leaked out operating and auxil-iary materials completely.

– Dispose of operating and auxiliarymaterials according to the disposalprovisions in force.

– In case of doubt, refer to the local dis-posal authorities.

Assembly instructions– Disassemble air cap, nozzle and needle. Ä 8.3.1 “Replace needle and nozzle.”– Thread the ball sealer (10).– Turn in and tighten screw bit (9) with pre-assembled seal (8) and pre-assembled

inner tube with nozzle (7) into the gun.– Push housing (4) with seal (5), pre-assembled outer tube(6) and locknut (3) on to the

inner tube (7).– Fit and tighten cap nut (1) with sealing ring (2).– Set outer tube (6).

The outer tube (6) is adjustable and allows varying setting positions of the air capto the nozzle. The farther the nozzle projects over the front side of the air cap, thebroader is the spray jet. Projection of the nozzle above the air cap should be min-imal.

– Tighten the locknut (3).– Push in needle (11) carefully into the gun housing from the back.– Insert needle spring, bearing and set screw again. Ä 8.3.1 “Replace needle and

nozzle.”– Purge the gun with solvent. Ä 6.7 “Rinsing”– Set the material flow. Ä 5 “Commissioning”
