INSTALLATION
For maximum transfer efficiency, do not use more
pressure than is necessary to atomise the material
being applied. NOTE: when using the HVLP do not
exceed 1.75 bar inlet pressure.
1. Connect the gun to a clean, moisture and oil free
air supply using a conductive hose, of at least 8
mm I.D.
Note
Depending on hose length, larger I.D. hose m a y
be required. Install an air gauge at the gun
handle. When gun is triggered on, adjust
regulated pressure to 2.0 bar for High Efficiency
Aircaps and 1.75 bar for HVLP. Do not use more
pressure than is necessary to atomise the
material being applied. Excess pressure will
create additional overspray and reduce transfer
efficiency.
Note
If quick connect couplings are required, use only
high flow quick connects approved for HVLP use.
Other types will not flow enough air for correct
gun operation.
Note
If an air adjusting valve is used at the gun inlet,
use DGIPRO-502-BAR Digital Gauge. Some
competitive adjusting valves have significant
pressure drop that can adversely affect spray
performance. The DGIPRO Digital Gauge has
minimal pressure drop, which is important for
HVLP spraying.
2. Insert the filter (48) into
the inlet of the Gravity
Cup.
Make sure the body of
the filter is pushed fully
so the body of the filter
does not protrude from
the cup insert.
3. Attach the gravity feed
cup to the material inlet.
Note
Before using the gun, flush it with solvent to
ensure that the fluid passages are clean.
OPERATION
1. Mix coating material to manufacturer’s
instructions and strain material.
2. Fill the cup to no more than 20 mm from the top
of the cup. DO NOT OVERFILL.
3. Attach C up Lid.
4. Turn fluid adjusting knob (28) clockwise to
prevent fluid needle movement.
5. Turn spreader valve adjusting knob (16) counter
clockwise to fully open.
6. Adjust inlet air pressure if required.
7. Turn fluid adjusting knob (28) counter clockwise
5 turns for full needle travel.
8. Test spray. If the finish is too dry, reduce airflow
by reducing air inlet pressure.
9. If finish is too wet, reduce fluid flow by turning
fluid adjusting knob (28) clockwise. If atomisation
is too coarse, increase inlet air pressure. If too
fine, reduce inlet pressure.
10. The pattern size can be reduced by turning
spreader valve knob (16) clockwise.
11. Hold gun perpendicu lar to surf ace bein g sprayed.
Arcing or tilting may result in uneven coating.
12. The recommended spray distance is 150200mm.
13. Spray edges first. Overlap each stroke a
minimum of 75%. Move gun at a constant speed.
14. Always turn off air supply and relieve pressure
when gun is not in use.
PREVENTIVE MAINTENANCE &
CLEANING
To clean air cap and fluid nozzle, brush exterior with
a stiff bristle brush. If necessary to clean cap holes,
use a broom straw or toothpick if possible. If a wire or
hard instrument is used, extreme care must be used
to prevent scratching or burring of the holes which
will cause a distorted spray pattern.
To clean fluid passages, remove excess material
from cup, then flush with gun wash solution. Wipe the
gun exterior with a dampened cloth. Never
completely immerse in any solvent or cleaning
solutions as this is detrimental to the lubricants and
life of the spray gun.
Note
When replacing the fluid nozzle or fluid needle,
replace both at the same time. Using worn parts can
cause fluid leakage. See page 13, Chart 2. Also,
replace the needle packing at this time. Torque the
fluid nozzle to 18–20 Nm. Do not over tighten.
CAUTION
To prevent damage to fluid nozzle (8) or fluid needle
(24), be sure to either 1) pull the trigger and hold
while tightening or loosening the fluid nozzle, or 2)
remove fluid adjusting knob (28) to relieve spring
pressure against needle collar.
CAUTION
IMPORTANT - the Gravity cup is made from special
anti-static materials, but it i s still im por tant to avoi d
generating static charges. The Cup must not be
cleaned or rubbed with a dry cloth or paper. It is
possible to generat e a s tat i c c harge by rubbing which,
if discharged to an earthed object could create an
incendive spark and cause solvent vapours to ignite.
Only use a dampened cloth or antistatic wipes if
manual cleaning is required within a hazardous area.
