Preparation Instructions

Preparing the Air Supply for Use
This air tool operates at max. pressure of 2bar (30psi). The compressed air system must be controlled by a combination pressure regulator and moisture filter; this will ensure a constant supply of dry air at all times, provided it is properly maintained.
Important: Always check the machine operating pressure before use.
Water in the compressor tank may cause considerable corrosion to air tools; the compressor should be drained daily to avoid excessive water in the air supply. Dirty or wet air can significantly shorten the lifespan of the product. When using an air tool with a hose over 25ft long, Draper Tools recommends increasing the bore of the hose to the next largest available size (i.e. increase 3/8” to 1/2”). This will ensure adequate pressure and volume of air to power the tool.

CAUTION! DO NOT lubricate the air line when using paint spray guns. Ensure that any oil device has been removed and any residual oil is purged from the system before connecting the spray gun.

Cleaning the Product and Accessories Before First Use
Before first use, the spray gun must be cleaned thoroughly to remove any oil, grease and protective film applied before shipment.

1. Disassemble the spray gun and immerse all parts and accessories in spray gun cleaning fluid.

2. Soak the parts for a few minutes.

3. Allow the parts to dry and then wipe them clean with a damp cloth.

4. Assemble the spray gun (see 7.3) and half-fill the paint cup (8) with thinners.
   Important: DO NOT connect the spray gun to the regulator or air line at this time.

5. Squeeze the trigger (12) to flush the thinners through the spray gun until the paint cup is empty.

6. Immerse and soak the assembled spray gun in the cleaning fluid for a few more minutes.

7. Allow the parts to dry and wipe them clean.

Assembly, Filling and Connection
Important: Draper Tools recommends using a 1/4″ BSP thread whip hose (Stock No. 54438) to connect the spray gun to an air line in order to reduce vibration.

1. Insert the paint filter (C) fully into the spray gun paint inlet (9) with the needle pointing downwards.

2. Attach the paint cup (8) to the spray gun inlet.

3. Rotate the fluid control dial (4) clockwise as far as possible to close the fluid valve.

4. Wrap a length of PTFE tape around the spray gun air line inlet (3).
   Important: For a more secure seal, the PTFE tape should be wrapped in the opposite direction to the thread.

5. Screw the 1/4″ airline coupling (D) onto the spray gun air inlet.
   Important: If using a whip hose, attach a parallel union nut (Stock No.

25823. instead of the air line coupling. Wrap a length of PTFE tape around the whip hose outlet thread and attach it to the parallel union nut.

6. Connect the airline to the airline coupling or whip hose.

7. Unscrew the paint cup lid and pour in the required quantity of paint.
   Important: ALWAYS ensure that the paint is mixed and thinned to the manufacturer’s recommendations.

8. Pressurise the air line when you are ready to begin.

Operating Instructions

Important: Before using this product, read and understand all the safety instructions listed in this manual. DO NOT make any adjustments to the spray gun while the trigger is depressed.

The Air Control Dial
The air pressure can be fine-tuned by adjusting the air control dial (2) on the spray gun. This is used to make minor adjustments to the air flow after the required air pressure has been set by the airline regulator.

• To increase the airflow: Rotate the dial clockwise.
• To decrease the airflow: Rotate the dial anticlockwise.

Important: The air control dial should typically remain in the fully open position to allow the full flow of air into the spray gun, but it may be used to make minor adjustments for specific operations. The dial will click when it has been wound to its fully open position.

The Fluid Control Dial
The fluid control dial (4) adjusts the amount of paint that is released into the airflow and the density of the spray when the trigger is fully depressed:

• To increase the paint quantity and density: Rotate the nozzle regulator anticlockwise.
  • The paint quantity should be increased when the spray gun is positioned further from the surface or when the paint mixture has a higher viscosity.
• To decrease the paint quantity and density: Rotate the nozzle regulator clockwise.
  • The paint quantity should be decreased when the spray gun is positioned closer to the surface or when the paint mixture has a lower viscosity.

The Spray Control Dial
The spray control dial (10) adjusts the shape of the paint jet released from the nozzle. The spray control dial can be rotated more than 360°.

• Fuller, flatter pattern: Rotate the dial clockwise.
• Narrower, rounder pattern: Rotate the dial anticlockwise.

The Air Cap
The air cap (1) has three types of opening that affect the pattern of the fluid spray:

• A hole for the nozzle head from which the fluid is dispersed (13).
• Atomizing air holes (14) that break the fluid into a fine spray.
• Air horn holes (15) that shape the spray pattern as required.

Once the spray pattern has been set using the control dial, rotate the air cap to change the orientation of the jet.
Important: ALWAYS ensure that the air cap remains tightly secured after adjusting its orientation.

The Trigger
Paint is released from the spray gun by squeezing the trigger (12):

1. First, squeeze the trigger until resistance is met; this opens the air valve.
2. Squeeze the trigger the rest of the way to draw the fluid pin back and release paint from the nozzle.

Important: Draper Tools recommends that you test the spray output on an area of scrap material before working on the genuine surface. Adjust the control dials to produce an even flow in the desired pattern. ALWAYS release the trigger before making any adjustment to the spray gun.

Notes on Use

• Keep the spray gun 6–12″ away from the surface during operation.
• Start moving the spray gun BEFORE squeezing the trigger to prevent a build-up of paint at the starting point.
• Move the spray gun with a smooth motion, keeping it perpendicular to and at a constant distance from the surface at all times.
• DO NOT rock or pivot the spray gun as this will deliver uneven coverage of the surface.
• DO NOT hold the spray gun in a static position while the trigger is depressed as this will deliver uneven coverage.
• Slightly overlap the movements of the spray gun to ensure an even distribution at the edges of each stroke.
• Use a piece of scrap material at the edges of the area to prevent overspray and protect other surfaces.
• Alter the speed of the movement, the distance from the surface and the fluid control dial setting to adjust the thickness of the paint applied to the surface.
• Release the trigger BEFORE completing the spray gun movement at the end of the final stroke to prevent a build-up of paint at the finishing point.
