13. MAINTENANCE
12. CLEANING
- 21 -
The spray gun, hoses and the rest of the unit must be
cleaned with the appropriate thinner, in order to remove
any remaining product after each use. The useful service
life of the unit depends largely on the effectiveness of the
cleaning process.
The unit must be cleaned:
1.- Before using it for the first time, in order to eliminate the
traces of maintenance oil that the equipment comes
withfrom the factory.
2.- After each use.
3.- When proceeding to apply a different product (different
colour or characteristics) to what we are currently using.
Before proceeding to clean the unit you must have
followed each and every one of the steps described in
the section Stopping when work is finished (Section
11.2). This implies that the unit and its accessories
must be depressurized and without any product
inside.
Always use an appropriate thinner when cleaning the unit.
Always use water for waterborne products, for other
products always use whatever is recommended by the
manufacturer of the product to be applied.
1.- Add the thinner to the gravity tank (No1 Fig.1) or to the
external container where the suction probe (No2 Fig.1) is
located, by inserting the product return hose (No3 Fig.1).
2.- Set the motor swich (No. 8 Fig.1) to the setting “on”.
3.- When the solvent starts to flow through the product
return hose (No3 Fig.1) close the return key (No4 Fig.1).
4.- Turn the pressure regulator control (No5 Fig.1) to adjust
the working pressure.
5.- Pull the spray gun trigger, holding it until the sprayed
product is clean thinner and free from the productprevious-
ly applied.
It is considered that the unit and its accessories are
totally clean when the product sprayed through the
gun, and that circulating through the product return
probe (No2 Fig.1), is clean thinner and free from the
product previously applied, meaning that the process
must be repeated as many times as necessary.
Once the unit and its accessories are clean, and as a
prior step before definitively stopping it, the Depressu-
risation procedure described before in Section 9 of the
Manual must be applied.
Clean the Suction Probe filters or the product cup and
those of the spray gun.
Remove any remains of product from the gun, hoses and
the rest of the unit with a cloth soaked in thinner.
Keep gasket areas free of accretions and foreign bodies.
The air cap is a precision component. Any deformation,
especially in the product outlet orifices, may cause
malfunctions in its operation and incorrect or deficient
quality spraying.
If necessary, dip the air cap in thinner in order to soften the
remains of product or dirt. Once softened, blow the cap
with compressed air until any remains of product and
thinner are eliminated.
For automatic cleaning of the gun, tools and accessories
used in the mixing and preparation of the product to be
applied, we recommend the use of SAGOLA Washing
Machines.
IMPORTANT
The gun can be cleaned with thinners or detergents in a
gun washing machine.
If you opt for this cleaning system, we advise you to
remember the following considerations, which, if not
applied, may damage the gun and render the warranty null
and void.
1- Do not submerge the gun in solvent or detergents longer
than the time required for cleaning.
2- Do not use the gun immediately after cleaning has been
completed.
3- Ensure that there is no thinner or detergent inside and
that it is completely free of these. Other cleaning systems
can be used (ultrasound).
Before starting to work, verify the state of the product
hoses and the connections of the elements through which
the product flows.
CHECK AND FILL EVERY DAY WITH THE LUBRICANT
SAGOLA 30090098, IF NECESSARY, THE EXISTING
ACCOMMODATION IN THE GLAND (9). REPLACE IF
DIRTY OR DAMAGED.
In order to carry out maintenance or repairs, first discon-
nect the unit from the compressed air distribution network.
Never move the unit by tugging on the hoses.
Always place the unit at a distance of least 6 metres away
from where the product is to be applied.
Do not apply excessive force or inadequate tools for main-
taining and cleaning the unit. Some repairs must be done
with special tools on some occasions. In these cases, you
must contact the Customer Service of SAGOLA. Any hand-
ling of this product by non-authorised personnel would
render the warranty null and void.
The unit must be overhauled on a periodic basis to check
the status of its components and replace these when they
are not in perfect condition.
IN ORDER TO OBTAIN THE BEST POSSIBLE
RESULTS, ALWAYS USE ORIGINAL SAGOLA SPARES
THAT GUARANTEE TOTAL INTERCHANGEABILITY,
SAFETY AND PERFECT OPERATION.
