Important information that tells how to prevent damage to the equipment or how to avoid causes of minor injuries will follow.Danger of skin injectionDanger of re from solvent and paint fumesDanger of explosion from solvent, paint fumes and incompatible materialsDanger of injury from inhalation of harmful vapors
i
Notes give important information which should be given special attention.HAZARD: INJECTION INJURY
Attention: Danger of injury by injection! A high pressure stream produced by this equipment can
pierce the skin and underlying tissues,
leading to serious injury and possible amputation.Do not treat a spraying injury as a harmless cut. In case of injury to the skin through coating materials or
solvents, consult a doctor immediately for quick and expert treatment. Inform the doctor about the coating material
or solvent used.PREVENTION:
•NEVER aim the gun at any part of the body. •NEVER allow any part of the body to touch the uid stream. DO NOT allow body to touch a leak in the uid hose.•NEVER put your hand in front of the gun. Gloves will not provide protection against an injection injury.•ALWAYS lock the gun trigger, shut the uid pump o and release all pressure before servicing, cleaning the tip guard, changing tips, or leaving unattended. Pressure will not be released by turning o the engine. The PRIME/SPRAY valve or pressure bleed valve must be turned to their appropriate positions to relieve system pressure.•ALWAYS keep tip guard in place while spraying. The tip guard provides some protection but is mainly a warning device.•ALWAYS remove the spray tip before ushing or cleaning the system.•NEVER use a spray gun without a working trigger lock and trigger guard in place.

35
safety precautiOns
PS 3.29 / 3.31
•All accessories must be rated at or above the maximum operating pressure range of the sprayer. This includes spray tips, guns, extensions, and hose.HAZARD: HIGH PRESSURE
HOSE
The paint hose can develop leaks from
wear, kinking and abuse. A leak can inject material into the skin. Inspect the hose before each use.PREVENTION:
•Avoid sharp bending or kinking of the high-pressure hose. The smallest bending radius amounts to about 20 cm.•Do not drive over the high-pressure hose. Protect against sharp objects and edges.•Replace any damaged high-pressure hose immediately.•Never repair defective high-pressure hoses yourself!•Electrostatic charging of spray guns and the high-pressure hose is discharged through the high-pressure hose. For this reason the electric resistance between the connections of the high-pressure hose must be equal to or lower than 1MΩ.•For reasons of function, safety and durability use only original Wagner high-pressure hoses.•Before each use, check all hoses for cuts, leaks, abrasion or bulging of cover. Check for damage or movement of couplings. Immediately replace the hose if any of these conditions exist. Never repair a paint hose. Replace it with another earthed high-pressure hose.•Make sure power cord, air hose and spray hoses are routed in such a manner to minimize slip, trip and fall hazard.

36
safety precautiOns PS 3.29 / 3.31
HAZARD: EXPLOSION OR FIRE
Flammable vapors, such as solvent and paint vapors, in work area can ignite or explode. PREVENTION:
•Do not use materials with a ashpoint below 38° C (100° F). Flashpoint is the temperature at which a uid can produce enough vapors to ignite.•Do not use the unit in work places which are covered by the explosion protection regulations.•Provide extensive exhaust and fresh air introduction to keep the air within the spray area free from accumulation of ammable vapors.•Avoid all ignition sources such as static electricity sparks, electrical appliances, ames, pilot lights, hot objects, and sparks from connecting and disconnecting power cords or working light switches.•Do not smoke in spray area.•Place sprayer sucient distance from the spray object in a well ventilated area (add more hose if necessary). Flammable vapors are often heavier than air. Floor area must be extremely well ventilated. The pump contains arcing parts that emit sparks and can ignite vapors. •The equipment and objects in and around the spray area must be properly grounded to prevent static sparks.•Use only conductive or earthed high pressure uid hose. Gun must be earthed through hose connections.•Power cord must be connected to a grounded circuit (electric units only).•Always ush unit into separate metal container, at low pump pressure, with spray tip removed. Hold gun rmly against side of container to ground container and prevent static sparks.•Follow material and solvent manufacturer’s warnings and instructions. Be familiar with the coating material’s MSDS sheet and technical information to ensure safe use.•Use lowest possible pressure to ush equipment.•When cleaning the unit with solvents, the solvent should never be sprayed or pumped back into a container with a small opening (bunghole). An explosive gas/air mixture can arise. The container must be earthed.•Do not use a paint or solvent containing halogenated hydrocarbons. Such as chlorine, bleach, mildewcide, methylene chloride and trichloroethane. They are not compatible with aluminum. Contact the coating supplier about compatibility of material with aluminum.

1.2 ELECTRIC SAFETY
Electric models must be earthed. In the event of an electrical short circuit, earthing reduces the risk of electric shock by providing an escape wire for the electric current. This product is equipped with a cord having an earthing wire with an appropriate earthing plug. Connection to the mains only through a special feed point, e.g. through an error protection insallation with INF < 30 mA.DANGER — Work or repairs at the electrical equipment may only be carried out by a skilled electrician. No liability is assumed for incorrect installation. Switch the unit o. Before all repair work, unplug the power plug from the outlet.Danger of short-circuits caused by water ingressing into the electrical equipment. Never spray down the unit with high-pressure or high-pressure steam cleaners.WORK OR REPAIRS AT THE ELECTRICAL
EQUIPMENT:
These may only be carried out by a skilled electrician. No liability is assumed for incorrect installation.1.3 ELECTROSTATIC CHARGING
FORMATION OF SPARKS OR
FLAMES
Electrostatic charging of the unit may occur during spraying due to the ow speed of the coating material. These can cause sparks and ames upon discharge. The unit must therefore always be earthed via the electrical system. The unit must be connected to an appropriately-grounded safety outlet.An electrostatic charging of spray guns and the high-pressure hose is discharged through the high-pressure hose. For this reason the electric resistance between the connections of the high-pressure hose must be equal to or lower than 1 MΩ.

2.2 COATING MATERIALS
PROCESSIBLE COATING MATERIALS
i
Pay attention to the Airless quality of the coating materials to be processed.Dilutable lacquers and paints or those containing solvents, two-component coating materials, dispersions, latex paints, release agents, oils, undercoats, primers, and llers.No other materials should be used for spraying without Wagner’s approval.FILTERING
Despite suction lter and insertion lter in the spray gun, ltering of the coating material is generally advisable.Stir coating material before commencement of work.
i
Attention: Make sure, when stirring up with motor-driven agitators that no air bubbles are stirred in. Air bubbles disturb when spraying and can, in fact, lead to interruption of operation.VISCOSITY
With this unit it is possible to process highly viscous coating materials of up to around 25.000 MPa·s.If highly viscous coating materials cannot be taken in by suction, they must be diluted in accordance with the manufacturer’s instructions.TWOCOMPONENT COATING MATERIAL
The appropriate processing time must be adhered to exactly. Within this time rinse through and clean the unit meticulously with the appropriate cleaning materials.COATING MATERIALS WITH SHARPEDGED ADDITIONAL

3 DESCRIPTION OF UNIT
3.1 AIRLESS PROCESS
The main areas of application are thick layers of highly viscous coating material for large areas and a high consumption of material.A piston pump takes in the coating material by suction and conveys it to the tip. Pressed through the tip at a pressure of up to a maximum of 221 bar (22.1 MPa), the coating material is atomised. This high pressure has the eect of micro ne atomisation of the coating material.As no air is used in this process, it is described as an AIRLESS process.This method of spraying has the advantages of nest atomisation, cloudless operation and a smooth, bubble-free surface. As well as these, the advantages of the speed of work and convenience must be mentioned.3.2 FUNCTIONING OF THE UNIT
In the following there is a short description of the technical construction for better understanding of the function.Wagner PS 3.29 / 3.31 units are electrically driven high-pressure spraying units.A gear unit transfers the driving force to a crankshaft. The crankshaft moves the pistons of the material feed pump up and down. The inlet valve is opened automatically by the upwards movement of the piston. The outlet valve is opened when the piston moves downward.The coating material ows under high pressure through the high-pressure hose to the spray gun. When the coating material exits from the tip it atomizes.The pressure control knob controls the volume and the operating pressure of the coating material.3.3 TECHNICAL DATA

4.2 CONTROL PANEL INDICATORS
The following is a description of the control panel indicators.Pressure
Indicator
Service
Indicator
SERVICE INDICATOR
The Service indicator is on when the motor is commanded to run. This indicator is used by service centers to troubleshoot motor problems.PRESSURE INDICATOR
The pressure indicator shows the current operating pressure of the sprayer. It has three dierent indications: blinking yellow, solid yellow, and solid green.Blinking Yellow
When the pressure indicator is blinking yellow, the sprayer is operating between 0 and 1.4 MPa (14 bar). A blinking yellow pressure indicator means:•The sprayer is plugged in and turned “ON”•The sprayer is at priming pressure (little or no pressure)•It is safe to move the relief valve between positions•It is safe to change or replace the spray tip
i
If the pressure indicator begins blinking yellow when the pressure control knob is set at a higher pressure and the relief valve is in the SPRAY position, either the spray tip is worn or the sprayer is in need of service/repair.Solid Yellow
When the pressure indicator is solid yellow, the sprayer is operating between 1.4 MPa (14 bar) and 12 MPa (120 bar). A solid yellow pressure indicator means:•The sprayer is at the proper pressure setting for spraying stain, lacquer, varnish, and multi-colorsSolid Green
When the pressure indicator is solid green, the sprayer is operating between 12 MPa (120 bar) and 23 MPa (230 bar). A solid green pressure indicator means:•The sprayer is at the proper pressure setting for spraying oil-based and latex house paints•The sprayer is operating at peak performance at a high pressure setting•If the pressure indicator goes to solid yellow when the pressure is set so that it starts at solid green, it indicates one of the following: a. Tip Wear Indicator — when spraying with latex or at high pressure the solid yellow appears. This means the tip is worn and needs to be replaced. b. Tip Too Large — when a tip that is too large for the sprayer is put in the gun, the pressure indicator will turn from solid green to solid yellow. c. Fluid Section Wear — if a solid yellow pressure indicator appears when using a new tip and the pressure is set at maximum, service may be required (worn packings, worn piston, stuck valve, etc...).4.3 PRESSURE CONTROL KNOB SETTINGS

ALWAYS engage the gun trigger lock before removing, replacing or cleaning tip.A) The key to a good paint job is an even coating over the entire surface. Keep your arm moving at a constant speed and keep the spray gun at a constant distance from the surface. The best spraying distance is 10-12 inches (25 to 30 cm) between the spray tip and the surface.25 - 30 cm

B) Keep the spray gun at right angles to the surface. This means moving your entire arm back and forth rather than just exing your wrist.
Keep the spray gun perpendicular to the surface, otherwise one end of the pattern will be thicker than the other.B
C) Trigger gun after starting the stroke. Release the trigger before ending the stroke. The spray gun should be moving when the trigger is pulled and released. Overlap each stroke by about 30%. This will ensure an even coating.25 - 30 cm25 - 30 cm

6 HANDLING THE HIGHPRESSURE HOSE
i
The unit is equipped with a high-pressure hose specially suited for piston pumps.Danger of injury through leaking high-pressure hose. Replace any damaged high-pressure hose immediately.Never repair defective high-pressure hoses yourself!The high-pressure hose is to be handled with care. Avoid sharp bends and folds: the smallest bending radius is about 8” (20 cm).Do not drive over the high-pressure hose. Protect against sharp objects and edges.Never pull on the high-pressure hose to move the device.Make sure that the high-pressure hose cannot twist. This can be avoided by using a Wagner spray gun with a swivel joint and a hose system.
i
When using the high-pressure hose while working on scaolding, it is best to always guide the hose along the outside of the scaolding.
i
The risk of damage rises with the age of the high-pressure hose. Wagner recommends replacing high-pressure hoses after 6 years.
i
Use only Wagner original-high-pressure hoses in order to ensure functionality, safety and durability.7 INTERRUPTION OF WORK
