 Wear approved safety respiratory protection and safety eye goggles.

 If spraying isocyanate based finisher, wear approved respirator/clean air breathing apparatus and protect skin with latex gloves and an

impervious hooded coverall.

Remove ill fitting clothing. Remove ties, watches, rings and other loose jewellery and tie back long hair.

Locate the spray gun in a suitable work area. Keep area clean and tidy and free from unrelated materials and ensure that there is adequate

ventilation and lighting.

Keep children and unauthorised persons away from the work area.

When not in use, ensure that the air supply is turned off.

 Avoid unintentional operation of spray gun.

 DO NOT point spray gun at yourself, other persons or animals.

 DO NOT direct air from the air hose at yourself, other persons or animals.

 DO NOT carry the spray gun by the hose, or yank the hose from the air supply.

 DO NOT exceed the maximum air pressure of 50psi.

 DO NOT use the spray gun for any purpose other than that for which it is designed.

 DO NOT allow untrained persons to operate the spray gun.

 DO NOT get the spray gun wet or use in damp or wet locations or in areas where there is condensation.

 DO NOT operate the spray gun if any parts are missing or damaged as this may cause failure and/or personal injury.

When not in use, disconnect the spray gun from the air supply, clean thoroughly and store safely.

1. SAFETY INSTRUCTIONS

2. DESCRIPTION & SPECIFICATION

Fully polished metal gun body resists corrosion and has low affinity for paint, making this unit ideal for water based paints and easy to clean.

Adjustable paint, fan width and air regulator controls. High capacity pressure pot holds up to two litres of paint per fill. This unit is perfectly suited

to the commercial refinishing shop. Components from the HVLP-79/P are also available separately. Supplied with 1.7mm set-up with optional

set-ups available separately.

Set Up: ........................................ 1.7mm

Available Set Ups: ............................... 1.3, 1.4, 1.5, 2.0mm

Air Pressure:.................................... 15-50psi

Air Consumption: ................................ 10cfm

Pot Capacity: ................................... 2.0ltr

3. AIR SUPPLY

Recommended supply system is shown below.

3.1 Ensure that the spray gun trigger is in the "off" position before connecting to the air supply.

3.2 You will require an air pressure between 15 - 50psi, and an air flow according to the specification.

WARNING! Ensure that the air supply is clean and does not exceed 50psi while operating the spray gun. Too high an air pressure and/or

unclean air will shorten the product life, due to excessive wear, and may cause damage and/or personal injury.

3.3 Drain the air tank daily. Water in the air line will damage the spray gun and invalidate your warranty.

3.4 Clean compressor air inlet filter weekly.

3.5 Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose diameter should be

1/4” I.D. and fittings must have the same inside dimensions.

3.6 Keep hose away from heat, oil and sharp edges.

Check hoses for wear, and make certain that all connections are secure.

4. OPERATING INSTRUCTIONS

4.1 For best results, handle the gun correctly. It should be held perpendicular to the surface being

sprayed and moved parallel to it. Start the stroke before squeezing the trigger and release the

trigger before finishing the stroke. This will give more accurate control of the gun and the

material (see right).

4.2 Spray from a distance of 6 (150mm) to 10 inches (250mm), depending on the material and the

atomizing pressure. The material deposited should always be even and wet. Each stroke must

overlap the preceding stroke to obtain a uniform finish. To reduce overspray and obtain

maximum efficiency, spray with the lowest possible atomizing air pressure.

4.3 Controlling the fluid and the fan spray:

a) As the width of the spray is altered so the fluid flow must be adjusted to maintain the same

coverage. Use the fluid control screw (‘C’ in Section 6).

b) The direction of the fan spray, either horizontal or vertical, is adjusted by turning the air cap

to the desired position and then tightening the retaining ring.

Disconnect from the air supply before attempting any maintenance or cleaning. When reassembling

after maintenance, be sure to take care when screwing parts together. At first screw parts hand tight

to avoid cross-threading. If a part cannot easily be turned by hand, check that you have the correct

part, or unscrew, realign and try again. DO NOT use excessive force when reassembling.

5.1 SPRAY GUN

5.1.1 Immerse the front end of the gun only in solvent until the solvent just covers the fluid connection.

5.1.2 Use a bristle brush and solvent to wash off accumulated paint.

5.1.3 Do not immerse the entire gun in solvent. This will cause lubricants to dissolve and packing to dry out.

Dirty solvent may also clog the narrow passages in the gun.

5.1.4 Wipe the outside of the gun with a dampened solvent rag.

5.1.5 Lubricate the gun daily with a light machine oil. Be sure to lubricate the fluid needle packing, air valve

packing, side port control packing and trigger pivot point. Do not use lubricants containing silicone.

5.1.6 When finished spraying, flush the gun through with clean thinners.

5.2 AIR NOZZLE, FLUID NOZZLE & NEEDLE ASSEMBLY

5.2.1 To clean the nozzles, soak them in solvent to dissolve any dried material then blow them clean with air.

Handle all nozzles carefully and do not make any alterations in the gun.

5.2.2 If you need to probe the holes in the nozzles, be sure to use a tool that is softer than brass; do not use metal instruments.

5.2.3 Adjust the fluid needle valve so that when the gun is triggered, air flow occurs before fluid flow.

5. MAINTENANCE & CLEANING

THE PROBLEM THE CAUSE THE SOLUTION

Heavy atomization, poor centre pattern Fluid flow is too high for

the air pressure and flow

1. Increase air pressure by adjusting

regulator (A) and increase flow

adjusting regulator (B).

2. Reduce paint flow with regulator (C).

3. Paint may be too thick. If so, dilute it.

Poor atomization/heavy centre pattern Air pressure and flow too high for fluid flow 1. Reduce air pressure by adjusting

regulator (A).

2. Reduce air flow by adjusting regulator

(B) and increase fluid flow with

regulator (C).

Intermittent spray pattern Air entering the fluid supply 1. Tighten the connection between the

gun and the pot.

2. Tighten fluid nozzle with gun spanner.

3. Check if pot vent hole is blocked.

4. Check if pot is empty.

Heavy right or left side pattern Horn hole (A) blocked. In order to check, turn

the air cap (C), if the faulty pattern is now

upside down the hole must be cleaned.

1. Place the air cap in solvent.

2. Clean hole with compressed air or

with a wooden toothpick.

DO NOT use a metal probe which

will damage the hole.

Top heavy or bottom heavy pattern Possible paint build-up between fluid nozzle

and air cap (A).

1. Clean the air cap and the fluid

nozzle, check that they match.

2. Check needle for damage.
