Maintenance And Cleaning - Bosch PSP 260 Bedienungsanleitung

Take care to maintain the same distance to the surface
to be sprayed and make uniform movement (see Fig.
).
C
First, spray the corners or small decorative parts with
short spray bursts. Then perform the actual spraying
procedure.
Begin the spraying pass approx. 10 cm outside the
surface to be sprayed and also end it approx. 10 cm
beyond the surface. Spray from the edge to the mid-
dle, then work the surface in a crosswise manner (see
Fig. ). A uniform application is achieved when the
C
passes overlap by 4 to 5 cm.
Then spray the surface a second time in the crosswise
manner.
When spraying on a vertical surface, drops can form.
First, spray from a somewhat greater distance and al-
low the sprayed material to partially dry.
Never spray until the container is empty. The suc-
tion tube must always be immersed in the fluid. Oth-
erwise, the spray mist is interrupted and thick drops
are sprayed.

Maintenance and Cleaning

Before any work on the machine itself, pull the
s
mains plug.
Always keep the machine clean so that it functions
s
properly and accurately.
General Maintenance and Cleaning Instruc-
tions
The cleaning of the machine and the container 5 al-
ways takes place with the thinning agent suitable for
the spray material.
Never immerse the complete unit in cleaning agent!
s
For cleaning, spray through the machine with the thin-
ning agent or with water for water soluble material (use
the collecting basin).
After cleaning or use with water, briefly spray
resin- and acid-free oil (for example, sewing ma-
chine oil) through the machine for corrosion pro-
tection. Otherwise, the piston could become
blocked by rust.
Special Cleaning Instructions (see Fig.
1. Screw out the attachment knob 2.
2. Separate the motor housing 11 from the pump unit
7. See Fig.
3. Unscrew the nozzle 1 and remove the suction/
pressure valve 6 from the pump unit 7. Remove
the pump piston 10 together with the spring 9 from
the pump unit 7. Do not use force!
4. Make a tightly fitting valve ball passable through
piston opening 8 with the aid of a copper or brass
pin.
5. Place all parts in the appropriate thinning agent and
clean.
Never use hard objects for cleaning!
pump piston 10 must be free to move easily in the
pump housing.
6. Reassemble the parts in the reverse order.
For malfunctions, check the nozzle 1 and the suc-
tion/pressure valve 6 and replace as necessary.
After cleaning, briefly spray resin- and acid-free oil (for
example, sewing machine oil) through the machine for
corrosion protection.
