WARNING
Attention !! Read and understand all instructions carefullybefore operating equipment.
INJECTION HAZARD
This equipment generates very high fluid pressure. Sprayfrom the gun, leaks or ruptured
components can inject fluid through your skin and into your body and cause serious
bodilyinjury.
The spray gun should never be handled carelessly, nor spray directed toward any part of
the body. Keep your hands fingers away from spray gun nozzle.
Be sure equipment safely devices are operating properly before each use.
If anyfluid appears to penetrate your skin, get emergency medical care at once. Do not
treat as a simple cut. Tell the doctor exactly what fluid was injected.
FIRE HAZARD
Static electricityis created bythe high velocity flow af fluid through the pump and hose.
If every part of spray equipment is not propely grounded, sparking immediately. Check
the entire system for positive grounding.
GROUNDING
Before starting to work the pump must be connected to ground:
1.-
2.-
3.-
4.-
5.-
The pump must be connected to ground with a ground wire which is supplied
with the pump ( 4mm2of section and a clamp). See connection on page 9.
SPRAY GUN: obtain grounding through connection to a properly grounded
fluid hose and pump.
OBJECT BEING SPRAYED: use ground wire and clamp.
AIR COMPRESSOR: follow air compressor manufacturer ’s
recommendations.
Use only metal pails, which are conductive. Do not place the pail on a
nonconductive surface, such as paper or carboard, which interrups the grounding
continuity.

PRESSURE RELIEF PROCEDURE
1.-
2.-
3.-
4.-
5.-
6.-
7.-
8.-
Engage the gun safety latch.
Shut off the air to the pump.
Close the air inlet valve.
Disengage the gun safetylatch.
Hold a metal part of the gun firmily to the side of a grounded metal pail, and trigger
the gun safety latch.
Engage the gun safety latch.
Open the drain valve, having a grounded metal container ready to catch the drainage.
Leave the drain valve open until you are ready to spray again.
HOSE SAFETY
Tighten all fluid connections securelybefore each use. Never use a damage hose. Before
each use, check entire hose for cuts, leaks, abrasions, building cover, or damage or
movement of the hose couplings. If any of these conditions exist, replace the hose
immediately.
SPRAY GUN
It is recommended strain the fluid you are spraying if the contains particles which could
clog the spray tip.
Cleaning the spray tip
Clean off the front of the tip frequentlyduring the day’s operation and at the end of the
work day. Always follow the Pressure Relief Procedure. Then use a solvent soaked
brush toclean the spraytip and to keep fluid buildup from drying and cloggingthe spray
tip.
If the spray tip clogs while spraying, release the spray gun trigger, engage the trigger
safety, shut off the pump, and follow the Pressure Relief Procedure. Remove the spray
tip and blow out the obstructions with air from the front of the spray tip.
Normal daily flushing of your spray system and gun flushes away most buildup on the
filter. However, you should remove the filter frecuentlyand clean it.

AIR-ASSISTED-AIRLESS GUN J.1000
Flushinf the gun.
Relieve pressure, remove the spraytip and then flush thegun and spraywith a compatible
solvent.Always flush the gun before the fluid being sprayed can dry in it.
OPERATING INSTRUCTIONS
Follow all instructions above, be sure that fittings at pump outlet and at gun are tight.
Use two wrench to tighten the maing fitting. Do not install the spray tip at this time.
Put the suction tube into the paint container. Flush the pump with a compatible solvent
before using it.

SPRAYTIPS
When a tip is the wrongsize, or becomes the wrong size through wear, the spray pattern
worsens, coverage decreases, you have less control over the desired rate of coverage,
and it takes longer to finish the job. In the worst case, the pump supplying the tip can be
damaged. Because most architectural coating are abrasive, tip wear can happened quite
quickly. Notice as wear increases the orifice size, it decreases the fan width which greatly
affects coverage rates.
If tip shows excessive wear, replace it to maximize productivityand save paint.
MAINTENANCE (Cleaning)
It is recommended that at the end of each day, paint should be flushed from unit with
compatible solvent then reflused with mineral spirits.
1.-
2.-
3.-
4.-
5.-
Engage the gun safetyand follow the Pressure Relief Procedure.
Remove the spray tip and clean with a compatible solvent and soft brush.
Disengage the gun safety and follow the pressure relief procedure. Lift suction pipe
above paint level until pipe is empty. Introducing the suction pipe in a pail with
compatible solvent. Disengage gun safety and trigger gun into the paint pail until it
runs clear. Close the air inlet valve
Open the fluid drain valve. Remove the fluid filter and the gun filter and clean them
with solvent.
Flush the sprayer at the end of each work day and fill it with solvent to help prevent
pump corrosion.

For trouble free operation is absolutely essential that your sprayer be kept
clean and free of residual paint build-up on the internal parts.
It must be cleaned and lubricated after each use.
