This symbol indicates a potential hazard to you or to the equipment. 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

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.

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.

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.

HAZARD: HAZARDOUS

VAPORS

Paints, solvents, and other materials can be harmful if inhaled or come in contact with body. Vapors can cause severe nausea, fainting, or poisoning.PREVENTION:

•Wear respiratory protection when spraying. Read all instructions supplied with the mask to be sure it will provide the necessary protection. •All local regulations regarding protection against hazardous vapors must be observed.•Wear protective eyewear.•Protective clothing, gloves and possibly skin protection cream are necessary for the protection of the skin. Observe the regulations of the manufacturer concerning coating materials, solvents and cleaning agents in preparation, processing and cleaning units.HAZARD: GENERAL

This product can cause severe injury or property damage.PREVENTION:

•Follow all appropriate local, state, and national codes governing ventilation, re prevention, and operation. •Pulling the trigger causes a recoil force to the hand that is holding the spray gun. The recoil force of the spray gun is particularly powerful when the tip has been removed and a high pressure has been set on the airless pump. When cleaning without a spray tip, set the pressure control knob to the lowest pressure.•Use only manufacturer authorized parts. User assumes all risks and liabilities when using parts that do not meet the minimum specications and safety devices of the pump manufacturer.•ALWAYS follow the material manufacturer’s instructions for safe handling of paint and solvents.•Clean up all material and solvent spills immediately to prevent slip hazard.•Wear ear protection. This unit can produce noise levels above 85 dB(A).•Never leave this equipment unattended. Keep away from children or anyone not familiar with the operation of airless equipment.•Device weighs in excess of 36 kg. Three-person lift is required.•Do not spray on windy days.•The device and all related liquids (i.e. hydraulic oil) must be disposed of in an environmentally friendly way.

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.

2.1 APPLICATION

2.2 COATING MATERIALS

PROCESSIBLE COATING MATERIALS

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.

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

MATERIALS

These have a strong wear and tear eect on valves, high-pressure hose, spray gun and tip. The durability of these parts cane be reduced appreciably through this.Materials Object Size

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
