SP1800 FAQ's
How often should I service my compressor?
RELEVANT TO FULL RANGE
The answer depends on how often you use your compressor. If it is in continuous use (construction/workshop) it will require more regular servicing as per the maintenance schedule in the owners manual. If only occasionally (homeowner use) then the annual service as per the maintenance schedule should be adequate.
Can I buy spare parts for my compressor?
RELEVANT TO FULL RANGE
Yes, spare parts are available for the SP Tools range of compressors. Please contact your local stockist or use our Contact Us page for more information.
What pressure should my compressor cut out, the needle in the gauge goes into the red zone, is this ok?
RELEVANT TO FULL RANGE
SP Tools compressors are 10 BAR (145PSI) compressors. They are set at factory to cut out when they reach this pressure, often this pressure is shown inside the red zone on the tank gauge. This is normal. All SP Tools compressors are fitted with a safety valve that will activate if the compressor goes over pressure. If the safety valve activates you may need to check and adjust the pressure switch. Please use our "Contact Us" page for more information.
What oil does my compressor use, and how much does it require?
RELEVANT TO FULL RANGE
We recommend SP Tools Compressor oil or Castrol Aircol PD68 (or equivalent) for the compressor pump. The correct level is achieved when the oil reaches the top of the red dot at the centre of the oil sight glass when the compressor is on a level surface (refer to the owners manual). Please refer to the owners manual for the correct engine oil and quantity to be used in the engine for the SP17P petrol powered compressor.
My compressor no longer turns on, it was working fine the last time I used it?
RELEVANT TO SP11-12X, SP11-40X, SP12-50X, SP13-50X, SP14, SP17, SP18 & SP1800
First follow the trouble shooting guide in your owners manual. It is also possible that the thermal overload protection on the motor has tripped. Turn your compressor off using the red button on the pressure switch and unplug from the power outlet. Push to reset the thermal overload switch, this is found on the black capacitor box on top of the motor (belt drive) or at the rear of the compressor (direct drive). Plug your compressor back in and turn on using the red button on the pressure switch. There are several reasons why this switch may activate, the two most common are: Using the compressor with an extension lead, better practice is to use a longer air hose and remove the need for an extension lead. Or turning the compressor off at the wall while it is mid cycle, always use the red button on the pressure switch to turn your compressor off and on.
Is there an overload/reset switch for my SP25/35/50 Compressor?
RELEVANT TO SP25, SP35 & SP50
Yes, it can be found in the contactor box.
Why can I hear air leaking when my compressor turns off?
RELEVANT TO SP11-12X, SP11-40X, SP12-50X, SP13-50X, SP14, SP17, SP18, SP1800, SP25, SP35 & SP50
You may hear air leaking for a number of reasons, often it is the hose connections to the compressor and not the compressor itself. However you will need to inspect for the source of the leak. Check all outlet taps, tank drain valve and fittings (regulator, gauges etc.). If the leak is coming from the small pipe that connects to the underside of your pressure switch the Non-Return Valve may have cracked or become worn and will need replacing.
Do I need to "run in" my new compressor?
RELEVANT TO FULL RANGE
Yes, the run in period in minimal, follow the instructions in your owners manual. Remember to do your first oil change and tighten all nuts and bolts on time as per the instructions.
Why do I have water coming through my air hose?
RELEVANT TO FULL RANGE
Water is a by product of creating compressed air, it will collect in the bottom of your compressor tank and can also get into your air lines. Remember to drain your tank daily (after each use when you turn it off at night). Check your regulator/filter, this will filter out some of the moisture and may need emptying. Air driers can also be installed in line to remove moisture from the process if required.
