2. General Cauons
• Always follow safety precauons and warnings printed on paint container.
• Only use accessories supplied by the manufacturer. User assumes all risk and
liability when using spray guns, hoses or other parts not complying with minimum
specicaon and safety devices
• Inspect hoses before each use. Never use a damaged hose. High pressure in hoses
with wear, leaks or splits may cause the hose to rupture and cause serious personal
injury. Never try to stop or deect leaks with any part of your body.
• Use extreme cauon when cleaning spray p guard. DO NOT try to wipe o build up around the spray
p before following shut down procedure. Follow the Shutdown Procedure, then follow the spray p
manufacturer’s instrucons for removing and cleaning the spray p.
• Never aempt to change spray p or leave the unit unaended without rst shung o pump, releas-
ing uid pressure, and locking the trigger safety lock.
• Use extreme cauon when changing spray p. Follow the Shutdown Procedure, then follow the spray
p manufacturer’s instrucons for changing the spray p.
• Do not pull on hoses to move equipment, DO NOT kink or bend the hose sharply.
• Keep children or anyone not familiar with airless spray systems away from equipment and work area.
• Conducve metal containers must be used when ushing ammable uids through the system. Always
ush at low pressure with spray p removed. A metal part of the spray gun must be held rmly against
the grounded metal pail when ushing or relieving pressure from the gun.
• It is forbidden the use of the spray gun for dispensing ammable or highly toxic like gasoline, herbicides,
pescides..
• This spray gun was designed and built in accordance with all safety aspects and CE regulaons
• During spraying, due to the speed of ow paint, in parcular situaons may accumulate on the equip-
ment electrostac charges that in discharging phase my generate sparks or ame. Due to this parcular
condion, ensure the proper grounding through a uid feed exible and the pump properly grounded.
Injecon Hazard
High Pressure Painng can cause serious injury if the spray penetrates the skin. Do not point
the gun at anyone or any part of the body. The p guard provides some protecon against
accidental injecon injuries, but is mostly a warning device. Never put your hand, ngers or
body over the spray p. Gloves and clothing do not necessarily oer any protecon either.
Keep the gun trigger safety lever in locked posion when not spraying. Always have the p
guard in place while spraying. In case of penetraon seek medical aid immediately!
Note to physician: Injecon into skin is a serious traumac injury. It is important to treat the injury surgi-
cally as soon as possible. Do not delay treatment to research toxicity. Toxicity is a concern with some exoc
coangs injected into the blood stream. Consultaon with a plasc surgeon or reconstrucve hand surgeon
may be advisable. Be prepared to tell the doctor what uid was injected.

5. Set-up
The spray gun is designed specically for AirCombi spraying, i.e. the Spray gun can be used in Airless mode
as well as in Mixed Air mode. The atomizaon is accomplished by the pressure (adjustable from 0 up to 200
Bar) through a pump. The air is used to improve the atomizaon quality and to increase or decrease the fan
size by adjusng the proper fan regulator placed on the spray gun
WARNING: INJECTION HAZARD POSSIBLE. DO NOT SPRAY WITHOUT TIP IN PLACE. AL-
WAYS ENGAGE TRIGGER LOCK BEFORE REMOVING, REPLACING OR CLEANING TIP. NEVER
TRY TO CLEAN THE TIP WITH YOUR FINGERS.
To prevent hazardous concentraon of toxic and/or ammable vapors, spray only in a prop-
erly venlated spray booth. Do not operate the spray gun unless venlaon fans are op-
erang. Check and follow all of the Local and Naonal Codes/Standards regarding exhaust
velocity requirements. Check and follow all local safety and re codes.
5.1. Grouding
Check your local code and pump manual for detailed grounding instrucons. Use only electrically conduc-
ve uid hoses. Ground the spray gun through connecon to a properly grounded uid supply hose and
pump.
5.2. Assembling the spray nozzle
Warning: the proper nozzle size is essenal for a good atomizaon on which depends the nal result. The
nozzle size is determinated by the coangs used and the type of applicaon. Ask to the coangs’ manufac-
turer for the proper p size.
1. Place the trigger lock in horizontal posion in order to prevent accidental injecon
WARNING: Before each nozzle change, assure to release the pressure in the spray gun and disconnect air
supply.
2. Unscrew the nut
3. Remove the air cap
4. Remove the nozzle into the air cap
5. Place the nozzle into the air cap
6. Place the air cap complete with the nozzle into the spray gun
7. Screw the nut onto the spray gun
5.3 Spray Gun Filter
We suggest always to use a Gun Filter, unless the coangs used do not require it. The mesh size of the gun
lter is determinated by the nozzle size. See the table at page 10 for the suggested lter size.

5.4 Air hose connecon
Aenon: It is suggested to install an air lter on the gun air line to ensure a dry, clean air supply to the
gun. Dirt and moisture can ruin the appearance of your nished worked piece. Install an air pressure reg-
ulator on the gun air line to control air pressure to the gun. Install an air shuto valve on the gun air line
and on the pump air line, to shut o air to the gun. Use a 3/16” (5mm) or even larger air hose to minimize
excessive pressure drop in the hose.
1. Connect the air hose the air inlet placed on the gun.
2. Connect the other end of the air hose to the air pressure regulator placed on the pump
5.5 Material hose connecon
Note: Before connecng the uid line, blow it out with air and ush it with solvent. Use solvent which is
compable with the uid to be sprayed. If beer control of uid pressure is needed, install a uid regulator
on the uid line to beer control uid pressure to the gun.
3. Connect the material hose to material inlet placed on the gun.
4. Connect the other end of the material hose the material outlet placed on the pump.
Note: Only use hoses supplied or approved by the manufacturer
WARNING: Inspect hoses before each use. Never use a damaged hose. High pressure in hoses with wear,
leaks or splits may cause the hose to rupture and cause serious personal injury. Never try to stop or deect
leaks with any part of your body.

6. Hints for Airless & AirCombi Sprayer
WARNING: DO NOT BEGIN SPRAYING BEFORE READING THIS SECTION AND ALL PREVIOUS SAFETY INFOR-
MATION.
To disengage your trigger lock: Your spray gun is shipped from the factory with the trigger lock in the
engaged posion (horizontal). To disengage, turn the trigger lock down unl it is in a vercal posion. To
engage the trigger lock, turn it back to a horizontal posion.
6.1 Painng and Tip Selecon
Correct adjustment of pressure and proper p selecon are crucial to the
best spray paern....
1. In any situaon, the lowest pressure that gives an adequate spray paern
is the best pressure to use. It will give maximum pump and p life and
produce minimum overspray.
2. Typically, thicker materials require larger ps and higher pressures than
thinner paints do. Some very thick paints may require slight thinning (5-
10%) depending upon pump and p size and applicaon. Generally, thin-
ning is performed when a good spray paern cannot be obtained with an
appropriate p size at maximum pressure.
6.2 Spray Painng Method
1. Keep the gun perpendicular to the surface. Always hold the gun perpendicular to the surface with the
p approximately 12” from the surface. If held at an angle (up and down or side to side) paint will build
up unevenly and leave the work splotchy.
2. Move with a smooth arm stroke. Move the gun at a steady even pace while keeping the gun perpen-
dicular to the surface. Do not move the gun by exing your wrist. Fanning the gun will cause excessive
overspray and uneven coverage
Proper way to trigger spray gun Result of exing wrist while spraying
3. Start moving the gun before triggering. To get smooth overlap and prevent inial paint buildup, start
our stroke movement before pulling the trigger. At the end of the stroke release the trigger before stop-
ping. NOTE: To assure uniform paint coverage, overlap each stroke by 40% - 50%.
4. Intermient use. If you are spraying and decide to stop for several minutes, lock the spray gun trigger
and submerge the p in a container of the appropriate solvent. This will prevent paint from hardening
in the ny spray opening and clogging the p. Be sure to release the pressure by opening dump valve
and turn o pump.
