Connecting the base unit:
– Insert a bayonet lock (21) of the air hose securely into the
holes in the base unit port (26) according to the arrow
marks.
– Turn the bayonet lock a quarter turn clockwise.
Connecting to the spray gun:
– Insert the second bayonet lock (21) of the air hose se-
curely into the holes in the spray gun port (9) according
to the arrow marks.
– Turn the bayonet lock a quarter turn clockwise.
Note: Remove the air hose (20) before pouring in spray ma-
terial (quarter turn of the bayonet lock (21) anticlockwise;
pull the bayonet lock (21) out of the port (9)).
Changing the nozzle cap (see figures B1–B2)
The fine-spray system is supplied with three nozzle caps:
(10)
Paint white
Delivery con- Mounted
dition compartment (27) under the
"Wall" "Wood/glaze"
Application
Note: Check the spray material by stirring it before selecting
the nozzle cap. Thinner-viscosity material (e.g. wood paint)
can be sprayed better with the grey nozzle cap (11) or the
black nozzle cap (12), whereas thicker-viscosity material
(e.g. wall paint) can be sprayed better with the white nozzle
cap (10).
– To change the nozzle cap, unscrew the cap nut (3).
– Pull off the air cap (2).
– Unscrew the mounted nozzle cap.
– Open the holding clamp (24) and take the required nozzle
cap out of the accessory compartment (27).
– Screw the required nozzle cap into the thread in the spray
gun.
– Put the air cap (2) on the nozzle cap and tighten it with
the cap nut (3).
Operation
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.

Work preparation

Spraying on the sides of water bodies (lakes, rivers,
u
etc.) or neighbouring surfaces in the direct catchment
area is not permitted.
When purchasing paint, lacquer and spray material, pay at-
tention to their environmental compatibility.

Preparing the spray surface
The spray surface must be clean, dry and grease-free.
– Roughen smooth surfaces and then remove the sanding
dust.
When spraying, all non-covered surfaces can be contamin-
ated by the spray mist. Therefore, thoroughly prepare the
area around the surface to be sprayed:
– Carefully cover floors, furnishings, doors, windows as
well as door and window frames, etc. Painting substrate,
for example, is recommended for covering the floors.
– Fix the cover material in place. Cover material that is not
fixed in place securely can be detached or blown away by
the powerful air jet.
Carefully mask off plug sockets and switches. Un-
u
covered plug sockets and switches may cause a short-cir-
cuit and increase the risk of electric shock.
Preparing the spray material
– Stir the spray material thoroughly.
Using spray material at room temperature will yield a bet-
ter spray pattern.
– Dilute the spray material if necessary.
If the spray test does not produce a good spray pattern,
dilute in 5 % increments until an optimal spray pattern is
achieved.
Spray material
Wood preservatives, oils, glazes, impreg-
nations, water
Solvent-dilutable or water-dilutable (re-
commended) lacquers, primers, anti-rust
primers, radiator lacquers, thick-coat
glazes
Emulsion paints and latex paints (interior
wall paints)
When diluting, make sure that the spray material and
u
the diluting agent are compatible. When using a faulty
diluting agent, lumps can develop that can lead to clog-
ging of the spray gun.
When diluting the spray material, make sure that the
u
flash point of the mixture is above 55 °C again after di-
luting. Diluting substances such as solvent-based lac-
quers lowers the flash point.
Note the specifications of the paint manufacturer re-
u
lating to sprayability, e.g. in the technical information
sheet or data sheet. Make sure that you do not spray
any paints that are not suitable according to the man-
ufacturer's specifications.
Filling the spray material (see figures C1–C2)
Note: Remove the air hose (20) before pouring in spray ma-
terial (quarter turn of the bayonet lock (21) anticlockwise;
pull the bayonet lock (21) out of the port (9)).
– When using large buckets, pour the spray material into a
smaller transfer bucket (14) if necessary (e.g. 10 l wall
paint into an empty 2.5 or 5.0 l bucket).
