Husky H4850GHVSG Gravity Feed Composite HVLP Spray Gun Instructions

Operation

1

Operating the spray gun

□ A low pressure at the spray cap minimizes over-spray, eliminating paint waste .

□ This air operated spray gun is designed to perform a variety of painting, coating, and finishing applications using the power of compressor air . This gravity feed spray gun features the HVLP (high volume low pressure), which enhances the transfer efficiency resulting in a significant material savings compared to conventional spraying .

□ Do not exceed the maximum air pressure of 40 psi .

□ The trigger lever of this gun has a two-step design . Press the trigger lever to the first step to connect to the air source, ensuring that air flow fills the spray gun . Press the trigger lever to the second step to connect the paint material .

Controlling the pattern and fluid flow

□ Adjust the air pressure with the trigger pulled and the air control knob fully open . If reduced air pressure is desired for some areas of the spray job, use the air compressor regulator or air control to reduce pressure as necessary .

□ Increase the air flow by turning the air control knob clockwise . Reduce the air flow by turning the air control knob counterclockwise .

□ Set the pattern size to the desired shape . For a full pattern, turn the pattern control knob counterclockwise . For a round pattern, turn the pattern control knob clockwise .

□ Turn the fluid control knob fully clockwise until closed to control the fluid .

Peparing and loading the paint

□ Thoroughly mix and thin the paint in accordance with the paint manufacturer’s instructions . Most materials will spray readily if thinned properly .

□ Strain the material through cheese cloth or a paint strainer .

□ Fill the paint canister to the maximum of the 3/4 full capacity carefully .

□ Set up a piece of cardboard or other scrap material to use as a target . Adjust the spray gun for the best spray pattern and the best atomization option .

□ Test the consistency of the material by making a few strokes on a cardboard target . If the material still appears too thick, add a small amount of thinner . THIN WITH

CARE!! Do not exceed paint manufacturer’s thinning recommendations .

Painting with the sprayer

□ Begin spraying . Always keep the spray gun at a right angle to the work surface .

□ Keep the nozzle about 6 to 9 inches from the work surface throughout the stroke and always keep the gun in motion while spraying . Stopping gun movement in mid-stroke will cause a build up of paint and result in runs . Do not fan the gun from side to side while painting . This will cause a build-up of paint in the center of the stroke and an insufficient coating at each end .

□ Trigger the gun properly . Start the gun moving at the beginning of the stroke BEFORE SQUEEZING THE TRIGGER .

Release the trigger BEFORE STOPPING GUN MOVEMENT at the end of the stroke . This procedure will feather (blend) each stroke with the next without showing overlap or unevenness .

□ The amount of paint being applied can be varied by the speed of the stroke, distance from the surface and adjustment of the fluid control knob .

□ Use a piece of cardboard as a shield to catch overspray at the edges of the work to protect other surfaces . Use masking tape to cover other areas if needed .
