11 Locate the unit away from walls. Take all precautions to ensure that hot air exhausted from the engine
and driven machine cooling systems cannot be recirculated. If such hot air is taken in by the engine or
driven machine cooling fan, this may cause overheating of the unit; if taken in for combustion, the
engine power will be reduced.
12 Before moving the compressor, switch it off.
1.4 Safety during use and operation
1 When the unit has to operate in a fire-hazardous environment, each engine exhaust has to be
provided with a spark arrestor to trap incendiary sparks.
2 The exhaust contains carbon monoxide which is a lethal gas. When the unit is used in a confined
space, conduct the engine exhaust to the outside atmosphere by a pipe of sufficient diameter; do this
in such a way that no extra back pressure is created for the engine. If necessary, install an extractor.
Observe any existing local regulations. Make sure that the unit has sufficient air intake for operation.
If necessary, install extra air intake ducts.
3 When operating in a dust-laden atmosphere, place the unit so that dust is not carried towards it by the
wind. Operation in clean surroundings considerably extends the intervals for cleaning the air intake
filters and the cores of the coolers.
4 Close the compressor air outlet valve before connecting or disconnecting a hose. Ascertain that a
hose is fully depressurized before disconnecting it. Before blowing compressed air through a hose or
air line, ensure that the open end is held securely, so that it cannot whip and cause injury.
5 The air line end connected to the outlet valve must be safeguarded with a safety cable, attached next
to the valve.
6 No external force may be exerted on the air outlet valves, e.g. by pulling on hoses or by installing
auxiliary equipment directly to a valve, e.g. a water separator, a lubricator, etc. Do not step on the air
outlet valves.
7 Never move a unit when external lines or hoses are connected to the outlet valves, to avoid damage
to valves, manifold and hoses.
8 Do not use compressed air from any type of compressor, without taking extra measures, for breathing
purposes as this may result in injury or death. For breathing air quality, the compressed air must be
adequately purified according to local legislation and standards. Breathing air must always be
supplied at stable, suitable pressure.
9 Distribution pipework and air hoses must be of correct diameter and suitable for the working
pressure. Never use frayed, damaged or deteriorated hoses. Replace hoses and flexibles before the
lifetime expires. Use only the correct type and size of hose end fittings and connections.
10 If the compressor is to be used for sand-blasting or will be connected to a common compressed-air
system, fit an appropriate non-return valve (check valve) between compressor outlet and the
connected sand-blasting or compressed-air system. Observe the right mounting position/direction.
11 Before removing the oil filler plug, ensure that the pressure is released by opening an air outlet valve.
12 Never remove a filler cap of the cooling water system of a hot engine. Wait until the engine has
sufficiently cooled down.
13 Never refill fuel while the unit is running, unless otherwise stated in the Chicago Pneumatic
Instruction Book (AIB). Keep fuel away from hot parts such as air outlet pipes or the engine exhaust.
Do not smoke when fuelling. When fuelling from an automatic pump, an earthing cable should be
connected to the unit to discharge static electricity. Never spill nor leave oil, fuel, coolant or cleansing
agent in or around the unit.
