This document provides operating instructions for the SATAjet 4600 B RP/HVLP spray gun, a device designed for applying paints, lacquers, and other sprayable media using compressed air.
Function Description
The SATAjet 4600 B RP/HVLP is a spray gun used for professional painting applications. It operates by atomizing paint or other fluid media with compressed air, allowing for an even and controlled application on various surfaces. The gun features a handle, trigger, and a nozzle set comprising an air cap, fluid tip, and paint needle. Material flow and spray fan patterns (round/flat) can be adjusted for precise control. It also includes a ColorCode-System (CCS) for individual marking. The device is suitable for use in explosion-hazard areas classified as Ex-zone 1 and 2, provided specific safety guidelines are followed.

Usage Features
The spray gun is designed for straightforward operation. Before use, all screws, especially the fluid tip [2-1] and locking screw [2-5], should be checked for tightness. The paint channel [2-6] should be rinsed with a suitable cleaning solution. The air cap can be adjusted for vertical [2-7] or horizontal [2-8] spray patterns. The paint strainer [2-9] and gravity flow cup [2-10] are then installed. The gravity flow cup should be filled to a maximum of 20 mm below the upper edge, closed with the lid [2-11], and the anti-drip device [2-12] inserted. The connection nipple [2-13] is screwed onto the air inlet, and the compressed air hose [2-14] is connected.
Adjusting the spray gun inlet pressure involves pulling the trigger fully and setting the pressure according to the recommended values in Chapter 2, using either a SATA adam 2 [3-1], a separate gauge with [3-2] or without [3-3] a control device, or by regulating pressure at the compressed air circuit [3-4]. When using methods [3-2], [3-3], and [3-4], the air micrometer [1-13] must be fully open and in a vertical position.
Material flow [4-1], [4-2], [4-3], [4-4] is adjusted with the material flow control screw [1-11]. Keeping this fully open minimizes wear on the fluid tip and paint needle. The spray fan pattern can be adjusted to a flat fan [5-1] (factory setting) or a round fan [5-2]. For painting, the trigger [6-1] is pulled fully, and the gun is guided [6-2] at the recommended spraying distance.
Maintenance Features
Regular cleaning and maintenance are crucial for the spray gun's longevity and performance.
Cleaning:
- Always disconnect the spray gun from the compressed air circuit before cleaning.
- Empty the spray gun and gravity flow cup completely, disposing of paint material properly.
- Disassemble and install components carefully using only the included special tools.
- Use neutral cleaning solutions (pH 6 to 8); avoid acids, lyes, bases, pickling agents, or other aggressive cleaning agents.
- Never soak the spray gun in cleaning solution, and ensure cleaning solution does not enter air passages.
- Clean drillings with SATA cleaning brushes or nozzle cleaning needles only.
- Use SATA-recommended spray gun washing machines, ensuring air passages are pressurized with clean compressed air and the nozzle head points downwards during cleaning.
- Remove the spray gun immediately after cleaning.
- Never use ultrasonic cleaning devices.
- After cleaning, blow dry the spray gun, material passages, air cap (including thread), and gravity flow cup with clean compressed air to prevent corrosion.
- Check the spray pattern after cleaning the nozzle set.
Maintenance:
- Disconnect the spray gun from the compressed air circuit before any maintenance work.
- Disassemble and install components carefully using only included special tools.
Replacing the Nozzle Set [7-1], [7-2], [7-3], [7-4], [7-5], [7-6]:
- The nozzle set includes the paint needle [7-1], air cap [7-2], and fluid tip [7-3], which are hand-adjusted for a perfect spray pattern.

Replacing the Spindle of Round/Flat Fan Control [11-1], [11-2], [11-3]:
- Replace if air leaks from the fan control or if it malfunctions.
- Remove the old spindle [a] by removing screw [11-1] (Torx T20), knob [11-2], and unscrewing spindle [11-3] with a wrench (size 14).
- Clean any material or paint residues from the spindle pick-up with solvent.
- Install the new spindle [a, b] by screwing in spindle [11-3] and turning the spindle nut [11-3] to the 6 o'clock position with a wrench (size 6) [11-4].
- Position and assemble the control knob [c] by aligning knob [11-2] vertically and hand-tightening screw [11-1] (Torx T20) while holding the knob in position.
