5. OPERATING INSTRUCTIONS
5.1.
To adjust the width of the spray pattern turn the fluid control knob as indicated
in fig.4. To reduce the amount of material sprayed screw the knob in. To
increase the amount of material sprayed screw the knob out.
5.2.
Control the air flow using the trigger.
5.3.
If necessary re-adjust the spray pattern.
5.4.
Good results will be obtained using a combination of the above adjustments.
If you have no previous experience of spraying we suggest that you
experiment on a non-essential area first before performing the final spraying
operation
5.5.
For best results, handle the gun correctly. It should be held perpendicular to
the surface being sprayed and moved parallel to it. Start the stroke before
squeezing the trigger and release the trigger before finishing the stroke. This
will give accurate control of the gun and material (fig.6).
5.6.
Spray from a distance of about 6 to 10 inches. The material deposited should
always be even and wet. Each stroke must overlap the preceding stroke to
obtain a uniform finish.
6. CLEANING
6.1.
The gun must be cleaned immediately after you have finished using it. On no account must any paint be allowed to even partially
dry as this may make your gun unusable. Empty the paint container immediately and flush it out. If using water based paint refill with
clean water and operate the gun until it is spraying clean water only. If using an oil based paint, stain, or laquer clean the paint
container with the appropriate thinning medium then refill the container with the medium and operate the gun until all paint residue has
been flushed out.
6.2.
Clean the outside of the gun and the main unit with a soft cloth soaked in warm soapy water.
7. MAINTENANCE
7.1.
Switch off the unit and disconnect from the mains before performing any maintenance or cleaning. Disconnect the air hose from the
unit and from the spraygun. When reassembling after maintenance, be sure to take care when screwing parts together. At first screw
parts hand tight to avoid cross-threading. If a part cannot easily be turned by hand, check that you have the correct part, unscrew,
realign and try again. DO NOT use excessive force when reassembling.
7.2.
Cleaning the spray gun. To maintain the spray gun in peak operational condition the main parts as shown in fig.7 should be regularly
inspected and cleaned. Metal parts should be soaked in a suitable paint thinning medium. This will normally be the thinning agent
used for the paint that was last in the gun. Plastic parts can only be immersed in hot soapy water and brushed clean. Never soak
plastic parts in any solvents as this may cause the parts to disintegrate.
7.3.
To disassemble the gun for routine maintenance withdraw the fluid needle (D) first. To do this unscrew and remove the fluid adjusting
screw (E) and the spring behind it. Now withdraw the fluid needle. It may be necessary to squeeze the trigger slightly to dislodge the needle.
7.4.
Unscrew the air cap locking ring (A) and remove the air cap (B).
7.5.
Using a suitable spanner unscrew and remove the fluid cap (C).
7.6.
The fluid tube (F) is a push fit into the main body of the gun. To remove for cleaning simply pull it out of its seating.
7.7.
Clean metal and plastic parts as previously directed and then carefully reassemble the gun in the reverse order.
7.8.
Should any deterioration in the performance of your gun occur refer first to the trouble shooting guide below or return the gun to your
Sealey service agent.
fig. 7
7.9.
Cleaning the air filter.
The air filter should be cleaned on a regular basis. Remove the filter cover by pulling it off as shown in fig.8 and remove the foam filter.
If using water based paints clean the filter in mild soapy water and remove excess water by pressing in a soft cloth. Allow to dry flat
before reinstalling.
Where a build-up of non-water soluble paint has occurred the filter cannot be cleaned and will have to be replaced. Place the new
filter into the back of the filter cover and insert the tabs on the bottom edge of the cover into the slots in the main unit. Swing the cover
upwards until it snaps into place.
To prolong filter life place the main unit as far away as possible from the spraying area.
