How to use a 6 litre air compressor
Updated: 21.10.2026
The compressor is on the floor, the hose is still coiled, and the first job is a tyre, a blow-off, or a few brads. A 6 litre tank is small enough to lift and small enough that the motor will start again almost as soon as you use the air. This is how to use a 6 litre air compressor on that first afternoon: confirm the plug, close the drain, let the motor cut out, set the regulator below the tool's own limit, and drain the tank before you put it away. The machine is assumed to be chosen already. The five amazon.co.uk rows are on the [6 litre air compressor comparison](/hub/compressors/air-compressor-6l). We did not write a missing manual.

Before you plug it in
Read the plug before you look for a socket. UK mains are 230 V and the domestic plug is BS 1363. Hyundai's listing says a 13 A UK plug, and Bimson's highlight says UK 13 amp. ABAC's box list is a Type G adaptor and a manual, so fit that adaptor as the listing describes rather than assuming a moulded plug on the machine. Stanley's specification does not state a plug, and UK reviews say an EU or two-pin plug arrived in the box. Draper states a 1.7 m cable and does not name the plug. If the lead in your hand is two-pin and you cannot fit a correct plug, stop. That fitting is a competent person's job. Do not run a motor of about 1 kW through an unearthed adaptor because the tank is only 6 litres. Listing conflicts stay on the 6 litre air compressor buying guide.
Set the compressor on a firm floor where the motor can get air, not in a cupboard and not under a dust sheet. HSE's HSG39, written for workplaces, says a small transportable receiver should have its relief valve left able to work, and the outlet should not be blocked. You are not an employer because you own a DIY compressor. The physical point still holds in a garage: do not cover a running machine, and do not site it where it will cook. Check the drain is closed before the first start. A UK review of the Draper mentions a bottom drain for moisture. If you leave it open, the pump will run and you will not store pressure.
Fit the hose the outlet expects
Draper's title says a Euro quick coupling. Hyundai's bullets say Euro quick-release. A 1/4 inch BSP gun will not click into that coupling because the tank is full. The Draper's included-components line says the compressor. Hyundai reviews say there is no hose in the box. ABAC lists the adaptor and the manual. Stanley's components line says an air receiver tank, while the specification also lists a 1.5 m hose. Use what is actually in the carton, and buy the fitting that matches the gun rather than forcing a thread.
First run and the pressure switch
Follow the manual in the box for the first start. None of the kept saved listings includes a transcribed booklet, so this page cannot give you a universal switch sequence or a universal pressure. Close the regulator, or set it low, before you switch on. Let the motor run until it cuts out on its own. On a healthy 6 litre receiver that silence is the pressure switch, not a fault. UK reviews on the Stanley and the Draper say the motor then cuts back in within seconds once you use air. That is the reserve leaving a small tank. Bimson reviews that are satisfied say the machine reaches the preset and cuts out. If it never cuts out, or if it cuts out and the relief valve lifts at once, switch off and do not keep resetting it.
Set the working pressure on the regulator, below the maximum printed on the tool, not at the tank's 8 bar just because the compressor can reach it. The Draper title says 116 psi and an outlet gauge. Hyundai's description says 100 psi. Stanley and ABAC state 8 bar. Your brad nailer or stapler has its own ceiling in its own manual, often well below the tank maximum. The 6 litre air compressor for a nail gun page is that limit for fasteners. One Hyundai review says the unit arrived with no pressure regulator at all. If there is no regulator, you cannot set a tool pressure, and the listing's air-tools line does not invent one. That is a return, not a technique.
Oil-free, where the listing says it, means you do not add pump oil on the first afternoon. Draper, ABAC, Hyundai, and Bimson say oil-free. Stanley's specification cell does not. Do not pour oil into a pump the page has not described. Do expect the cylinder head to get hot after a few minutes. A long blow, with the motor running continuously, is how a small pump overheats. Stop while the tool still has pauses in it.
Drain the tank, and know when to stop
Water condenses in the receiver even when the pump is oil-free. Air Supply's UK note is to drain daily or after every use, because the water rusts the tank. Drop the pressure first. A trade manual for oil-free compressors, not the Draper or ABAC booklet, describes draining below about 10 psi with a container under the valve, then closing the valve afterwards. Use that only as the shape of the job. The valve on your machine is the one in its own manual. A teaspoon in the tray is still a reason to have opened the valve.
Leave the relief valve alone unless you are checking that it is free to move, and do not tie it down, cap it, or block it to stop a hiss. A UK review of the Draper says the relief valve on the unit does not match the drawing in the manual. A UK review of the Bimson says the manual reverses clockwise and anticlockwise for the outlet valve, that pressure stayed at maximum, and that the safety valve had no ring to pull. If the part in your hand does not match the drawing, stop. One Stanley review mentions missing safety-valve parts. That carton goes back.
Stop and get help, or use the retailer's returns route, when the motor smokes, when you smell burning, when the receiver is dented or weeping, or when the relief valve has lifted and will not reseat. One Draper review reports a burnt-out motor and a small fire. That is one report. It is also the end of a home procedure. A stated 97 dB on the Stanley and the Draper is a reason to keep the run short and to wear hearing protection as a practical step, not because a householder has become an employer under the Control of Noise at Work Regulations.
Common questions
What do I do before I switch a new 6 litre compressor on?
Confirm the plug is one you can put in a UK socket, or fit the Type G adaptor the ABAC listing includes. Close the drain. Put the compressor where it can get air, and connect a hose that matches the outlet. Set the regulator low, then switch on and wait for the motor to cut out. If the lead is a two-pin plug you cannot replace, do not start. The manual in the box still wins where it is specific.
Why does the motor stop and start so often?
The pressure switch is doing that on a 6 litre receiver. UK reviews of the Stanley and the Draper say the motor cuts in within seconds once the tank has been used, because the reserve is small. That is normal for intermittent brads, staples, and a short blow. It is a problem when the tool needs air the whole time, or when the motor never cuts out at all. Never cutting out is a stop, not a longer run.
Where do I set the pressure for a nail gun?
Set it on the regulator, at or below the maximum in the nailer's own manual. Do not set the tank's 8 bar, or the Draper's 116 psi, just because the compressor can reach it. If the Hyundai arrived without a regulator, as one UK review reports, you do not have a place to set that pressure. The regulator is the control, and the tool's limit is the number.
How do I drain the tank?
Switch off, let the pressure fall, put a container under the drain, open the valve, and close it again before the next use. Air Supply's advice is daily or after every use. A general oil-free manual describes doing this below about 10 psi. Your booklet, if it names a pressure, replaces that figure. A valve that will not shut is a leak to stop for, not a drain to leave open while you work.
The pump is oil-free. What is left to maintain?
You still drain condensate, you still keep the relief valve free, and you still let the pump cool between long runs. Oil-free means no oil top-up on the Draper, ABAC, Hyundai, and Bimson listings. It does not mean a dry tank. Stanley's specification does not say oil-free, so do not service it as if it had. Check the filter and the gauge for transit damage. Hyundai reviews report both arriving dented or smashed.
The relief valve does not look like the drawing. What should I do?
Stop, and do not run the compressor to test a guess. A Draper review says the valve on the machine differs from the manual. A Bimson review says the outlet-valve direction in the manual looks reversed and the safety valve had no ring. A Stanley review mentions missing safety-valve parts. Use the retailer's returns route or a competent person. Do not cap the outlet, and do not hold the valve shut.
When do I stop and get help?
Stop if the motor smokes, if the receiver is dented or weeping, if the relief valve has lifted, or if you cannot fit a safe UK plug. One Draper review describes a burnt-out motor and a small fire. A Bimson review describes an air leak out of the box and a refund. Those are not adjustments. Cycling every few seconds on a brad nailer is the small tank. Smoke, a leak at the shell, and a valve that does not match the manual are the point where a professional or the retailer takes over.
