•
halogenated hydrocarbons
(e.g. 1,1,1-trichloroethane, methylene chloride, etc.)
•
acids and acidiferous cleaning solutions
•
regenerated solvents (so-called cleaning dilutions)
•
paint removers.
The above constituents cause chemical reactions with the electroplated components
resulting in corrosion damage.
WALTHER Spritz- und Lackiersysteme is not responsible for any damages resulting
from such treatment.
Clean the spray gun
•
prior to each change of the spraying medium.
•
at least once a week.
•
as often as may be required by the spraying medium handled and the resultant
degree of fouling.
Attention
Never immerse the spray gun in solvent or any other cleaning solution. The functio-
nal reliability and efficiency of the gun can otherwise not be guaranteed.
Attention
Do not use any hard, pointed or sharp-edged objects when cleaning the spray gun.
Any damage of the precision-made parts are likely to affect your spraying results.
1.
Dismantle the spray gun in accordance with 5.5 Retooling the Spray Gun.
2.
Use a soft brush together with a compatible cleaning sulotion to clean the air cap
and nozzle.
3.
Clean the remaining parts and the spray gun body with a suitable cloth and
cleaning solution.
4.
Apply a thin film of the appropriate grease to the:
•
O-ring of the piston
•
needle spring
Make sure to use a non-acidic, non-resinogenic grease and a soft brush. The spray
gun is then reassembled in reverse order.
6.3
Cleaning - Routine
The spray gun need not necessarily be dismantled for cleaning if and when the
spray- ing medium is changed in regular intervals or upon termination of work
(depending on the material used).
Note
Clean and lubricate the spray gun frequently in accordance with Chapter
6.2 Cleaning - Complete. This will ensure functional reliability of the spray gun.
The following requirements must be met before the routine cleaning work can be
performed:
32
1.
The material tank must be claen and then be filled with a compatible cleaning
aolution. Material pressure has to be available at the spray gun.
The cleaning solution should not be sprayed.
2.
Take the spray gun into operation (see 5.2 Starting the Spray Gun).
3.
Do not stop the spray gun until clear cleaning solution emerges from the nozzle.

Repairs / Replacements
Warning
Prior to any repairs / replacements: Make sure that the spray gun is in unpressurized
condition, i.e. all air and material inputs must be shut off - if not, imminent risk of
injury.
Note
Please use the drawing at the beginning of these operating instructions to perform
the following procedures.
7.1
Replacement of defective Needle Packing
1.
Remove all pressures from the gun.
2.
Unscrew the needle gland nut (item 15).
3.
Pull out the needle seal packing (Item 14) with an auxilliary tool. Use a strong
wire on which one end is bent making a small hook.
4.
Lubricate the new needle seal with non-acidic, non-resinogenic grease.
5.
Install the new needle seal in the gun body.
Installation of the remaining parts is performed in reverse order.
Note
Never reinstall a used needle seal packing (Item 14) as otherwise the functional
sealing reliability of the spray gun will suffer.
7.2
Replacement of Nozzles, Needles, Springs and Seals
Dismantle the spray gun in accordance with Chapter 5.5 Repalcement of Material
Control Nozzle and Needle, if the following components have to be replaced:
•
Material Nozzle
•
Material Needle
•
Needle Spring*
•
O-Ring of the Piston*
Note
Parts marked with * must be lubricated with non-acidic, non-resinogenic grease prior
to installation.
