Clean the brim of the container and the lid with seal carefully with a soft cloth or brush
using a suitable thinner.
On no account use sharp-edged tools as these may damage the seal and the surface of the
container.
Dried paint residues on the air-head (Fig. 3, item 320) should not be scratched off with a hard
object. Immerse the air-head into a thinner for few minutes and then remove the residual with a
brush.
Attention!
After working with water-soluble paints such as acrylic paints, dispersions or binder
emulsions, the nozzle, nozzle-needle, trigger and the thread of the spring bushing (Fig.3, item
310) should be lightly oiled after cleaning.
If corrosive cleaning products are used, the spray gun components must be rinsed with clean
water immediately after cleaning and thoroughly dried to prevent corrosion.
Attention! Never immerse the complete spray gun or the lid with seal in corrosive
cleaning products, thinner or solvent. Also store no corrosive cleaning products, thinner
or solvent in the paint container. After cleaning of the spray gun do not tighten the lid so
that the seal not lose the elasticity.
If there is a leak in the cover seal of the paint container, or if it is defective, replace the seal.
8.2
Changing the Nozzle
Unscrew nozzle ring (Fig. 3, item 321), then take out air-head (Fig. 3, item 320). Change the
nozzle using nozzle spanner supplied (Fig. 3, item 322).
8.3
Removing the Nozzle Needle
Unscrew spring bushing (Fig 3, item 310) from the housing (Fig. 3, item 301), take out valve
disk (Fig. 3, item 308) and pressure spring (Fig. 3, item 309). Then unscrew setting screw
(Fig. 3, item 316) from spring bushing and push nozzle needle (Fig. 3, items 311 to 313) to rear.
In this way, the pressure spring (Fig. 3, item 314) complete with shim (Fig. 3, item 315) will be
ejected as well.
8.4
Fitting the Nozzle Needle
To fit the nozzle needle, reverse the sequence described above.
The nozzle needle is sealed by a packing (Fig. 3, item 306). The slotted screw (Fig. 3, item 307)
which engages in the thread of the nut (Fig. 3, item 305) presses the packing against the nozzle
needle. If paint emerges from the seal, tighten the slotted screw with the nozzle spanner
(remove nozzle needle). If the result is not satisfactory, renew the seal packing.
