Operating instructions
The 12V Air Compressor has been engineered to service even the largest tyres used on trucks, vans, 4X4’s
etc., but will equally as well on passenger cars.
Please read the entire instruction manual before use and retain for future reference.
IMPORTANT Your battery may not be at full strength. It is essential therefore that you keep your engine
running when operating the compressor. This will also shorten inflation time. Do not do this in a closed
garage due to the fumes circulating in a confined space.
1. Safety - Warning! Never leave the compressor unattended whilst it is in operation.
The compressor is not to be used for long period otherwise it may overheat. Using the compressor for
10 minutes at a time should assist in tyre inflation. If a prolonged period is required then switch off the
compressor and allow to cool for at least 10 minutes then resume. For higher pressures (pressure over 5 bar),
let the compressor rest after 7 minutes of continuous use. If the compressor overheats, switch it off and
let it stand for at least 10 minutes or until cool, if longer, before you start it again.
Tyres are marked with their maximum pressure in psi or bar – always refer to the manufacturers guide on tyre
pressure , never exceed the stated psi/bar
NOTE: The tyre will not expand at the same rate during the final phase of inflation as it does at the beginning
of this process. This is due to the fact that air flow into the tyre from compressor decreases as the required
tyre pressure is reached. Check with tyre pressure gauge to confirm required pressure has been reached.
INFLATION TIME Inflation time will vary depending on the article inflated and the pressure required.
2. Description of the components
12V air compressor with pressure gauge and cigar lighter plug. Includes a nozzle for inflating rubber dinghies
or airbeds (6), a nozzle for bicycle valves (7) and a nozzle for football valves (5).
• Insert the 12V plug into your 12V power socket.
• Push the pump connector onto the tyre valve and screw it on.
• Inflate the tyre to the recommended pressure (refer to the cars handbook or marking on the tyre itself).
• When completed unscrew the pump connector and unplug the compressor from the 12V power socket.

3. Operation; to inflate tyres
Car tyres should normally be inflated to pressures ranging from 1.65 bar (24 psi) to 2.2 bar (32 psi). Tyres
for large vehicles might need a pressure up to 2.75 bar (40 psi). Tyres are marked with their maximum
pressure in psi or bar.
To Inflate Bicycle Tyres
• The bicycle adapter should be used for inflating bicycle tyres, follow the instructions above.
Inflating Other Items e.g. inflatable toys, etc.
• Choose a suitable adapter nozzle or pump needle and insert it into the valve of the object which you
want to inflate.
• Insert the 12V plug into your 12V power socket to start the pump.
• Unplug the 12V power plug when the desired pressure has been reached.
NOTE! Toys and air mattresses can burst if you over-inflate them! Keep an eye on the pressure
continuously. Never pump to a higher pressure than the one which is recommended.
4. Disposal - Follow local guidance when disposing of this product. If you are unsure how to proceed,
contact your local authority.
5. Specifications
Power supply - DC 12V, (centre positive)
Air Flow Rate - 36L/Min @0psi
Current draw - Approx 10A at 6 bar
Max pressure - 10 bar (150 psi)
Length of lead - 3m
Air hose length - 1m
CAUTION:
1. Do not inflate items beyond their needs. To avoid over-inflation carefully follow instructions on articles
to be inflated. Do not exceed recommended pressures. Use the pressure gauge to check for the
correct pressure.
2. Bicycle tyres and other small articles will inflate relatively quickly. Be particularly careful not to
over inflate.
3. Recreational items such as beach toys and air mattresses require low pressure. Inflate until firm.
INSTRUCTIONS IF COMPRESSOR FAILS TO START
Note: If the 12V accessory socket in your vehicle is not working, the compressor will fail to operate.
Please check the following:
1. Check 12V socket for debris of any other foreign material that could be stopping good connection
between the 12V plug and socket. Isolate the socket and remove any foreign object.
2. 12V power socket fuse may be blown. If so replace in accordance with the vehicles owner's manual.
3. Some 12V power sockets have a circuit breaker located directly behind 12V power sockets.
Check and replace as necessary.
