The Bosch 2000 paint sprayer doesn’t pump paint
All about Bosch spray guns
Tinting of materials is a common process in human households. This way you can give a nice appearance to things that previously looked less beautiful. Thanks to currently available technology, such as spray guns, painting is not difficult. One of the manufacturers of such tools is Bosch.
Overview of the Bosch PFS 2000 spray gun
I want to tell you right away that this is my first experience with similar spray guns, so my opinion about this device was formed, so to speak, “from scratch”, not having the opportunity to compare it with competitors.
The spray gun comes in a colorful cardboard box, on which, there are images of the tool itself in operation, the data on its characteristics and purpose and the manufacturer. By the way, this tool is made by Bosch in Hungary.
I recommend not throw away the box, because it is compact enough to store the tool between uses, and since the set consists of several items, it reduces the risk of losing one of them. Of course, the cardboard box is not a plastic case, and over time, pretty quickly frayed and then have to pick up something else for storage (the manufacturer’s stated lifetime tool. 7 years, and I want to believe that he really will last long), but as they say, better this than nothing.
Base unit with an interchangeable shoulder strap;
Exchangeable container for the spreading material;
Replacement spraying cap (placed in a removable paint container);
A sieve for filtering the working material;
The set includes everything you need for work with the tool.
The glad thing is that the set includes a removable container, which makes the use of the tool more comfortable. You can prepare more spray liquid at once and just change the pail quickly as you go. In addition, the replacement tank has a screw cap that can be screwed on tightly, so that the material can be stored temporarily when not in use.
In the tradition of Bosch, there are no questions about the quality of materials and workmanship. Tool is made of durable plastic. The air hose is made of reinforced rubber, which prevents kinks while maintaining the necessary flexibility. The electric cable is well insulated and not rigid. Connection points (hose nipples) are easily secured in the assembly. Switches and switches accept the required positions clearly. Components are well assembled, with no gaps, clearances or backlashes.
Functionality and ease of use.
The Bosch PFS 2000 is designed for spraying dispersion and latex paints, water-soluble enamel paints, glazes, primers, varnishes, etching solutions and oils. The tool is not suitable for alkaline solutions, acidic materials and paints that can form explosive concentrations of vapors when applied.
The tool is one of the green tools from Bosch for non-professional/home use. The “Easy” difficulty level. And there is really no problem to use the spray gun. Easy to assemble, easy to use.
Assembly is quite simple and does not require any additional tools. Hang the air hose between the master unit and the spray gun through the thumbwheel on the connectors. Fit (change if necessary) the spraying cap that corresponds to the material to be sprayed. Pour the material into the replacement container and screw it onto the spray gun. The device is ready for operation.
I would like to focus on what I believe are the main points when working with the Bosch PFS 2000 spray gun in terms of functionality and user-friendliness.
Adjustment of the working material flow is provided for. For this purpose, there is a rotary knob on the body of the spray gun.
It is also possible to set the shape of the cloud/spot: horizontal (convenient when applying material in up and down movements); vertical (application of material in horizontal movements) and circular (for working on corners, edges and hard to reach places). To set the corresponding mode, simply set the rotary part of the spray nozzle to one of the three positions corresponding to the markings on the body of the spray gun. This is very easy to do while working and does not require the removal of any parts of the tool.
Included are 2 interchangeable spray caps: gray for more diluted, less viscous materials and white for more viscous materials (lacquers, paints).
Now about convenience. The sprayer runs on 220 V mains, so it needs to be plugged in at all times. Cable length of approx. 2.4 m, which may be insufficient in many cases, as larger surfaces are often painted (e.g. sienna or fence). an extension cord is needed. On the other hand, since such work involves moving in space, there is a risk that the cable will get tangled up in the legs. In this respect, cordless models are more convenient, but they also have their disadvantages (cost, need to recharge).
The tank for the working material with a capacity of 800 ml. On the one hand, a small tank capacity makes the work less tedious (light weight of the spray gun), on the other hand. the material is used rather quickly and you have to stop more often to change / refill the container. This can be particularly annoying when working in maximum flow mode, although, to be fair, it should be noted that in practice, in the vast majority of cases for the work are more applicable flow modes from low to medium.
Of the inconveniences associated with the tank, it should probably be noted that it is made of green plastic is not very transparent, which makes it difficult (especially in poor light conditions) to control the flow of material.

The tool itself is quite lightweight (2 kg) and the shoulder strap, which allows you to place the base unit on the weight, makes the work tireless.
I want to note that the tool is pretty noisy (according to the passport. 79 dB(A)), so when working long hours should use noise protective earplugs or headphones. Take care of your health, our greatest treasure. The noise is produced by the base unit and the spray gun itself.
My overall impression of the sprayer is positive. Note that so far I had a chance to try it only with pretty fluid (not viscous) water-base paint and water-base primer.
Work speed is faster than with a paint roller. It seems to me that time is mainly saved by not having to wet and squeeze out the excess fluid from the roller.
And the best thing about it is that nothing drips or runs off.
So, if you have quite an extensive scope of painting work (for example, repairing an apartment, painting a garage or a fence at the cottage), I think this paint sprayer can be a useful tool that will make the work more productive and comfortable.
Spray gun repair
Sprayer performance problems can be divided into 2 types: those affecting the operation process and those affecting the flare imprint. Both can have similar symptoms, so we’ll talk about each one separately and suggest solutions. Let’s start with functional problems.
|Paint comes out of nozzle when trigger is released||Needle cone not tightly covering the outlet The nozzle is not tightly tightened The needle is bent, worn or not lubricated. Parts are contaminated with dried paint. Spring is broken. Needle clamp nut is too tight||– Flush parts thoroughly. Tighten the nozzle with a special wrench. Loosen clamping nut. Apply a special lubricant to the rubbing parts of the needle. If necessary, replace deformed or worn parts|
|Air cap leaking||Seal not tight against the body Deformed o-ring||– Try to tighten. Replace the o-ring|
|Seal nut is leaking||– Weak tightening torque. Deformation of the gasket||– Tighten packing nut. Replace the gasket|
|Air comes out of air cap when trigger is released||– Air valve clogged with debris or paint. Air valve spring is broken||– Pull trigger, remove and clean air valve. If necessary, replace the spring|
|Trigger is squeezed too tight||– Air valve stem is deformed or dirty Replace gasket. Trigger needle or nut dirty. Needle packing nut too tight||– Check that the needle moves smoothly in its groove. Clean and lubricate as needed Check air valve and trigger mechanism for dirt and damage.|
|Air valve clogged with debris or paint The paint head is clogged too quickly||– Air pressure too high. Deformation of the gasket||– Relieve pressure. Replace the gasket between the head and the nozzle|
|Spray gun spits paint||– Needle and nozzle are worn and do not fit tightly together. Needle is not the right size. Parts are contaminated||– Clean needle and nozzle. If necessary, replace with new parts|
|Torch/air regulator does not turn||– O-ring is swollen. Threads are dirty||– Remove, clean and lubricate regulator Replace seal if necessary|
|Air bubbles coming out of cistern||– Nozzle not tightened properly or deformed||– Tighten the nozzle. Replace if damaged or worn|
|Intermittent atomization||– Nozzle is not screwed in tight enough. Not enough paint in the tank. Air vent in the tank is clogged. Paint is too thick. Mixture not passing through filter. Seal between paint head and air cap damaged||– Screw in nozzle snugly. Clean the tank vent and make sure there is enough paint. Dilute and filter the paint. Check the gasket and replace it if necessary|
