3. Safety
3.1 Specified conditions of use
This device is intended to generate compressed air required for the operation of air tools.
Any use for medical purposes, food processing as well as filling of oxygen cylinders for breathing equipment is not permitted.
Explosive, combustible gases or gases detrimental to health may not be compressed. Operation in hazardous locations is not permitted.
Any other use is not as specified. Use not as specified, alteration of the device or use of parts not approved by the equipment manufacturer, can cause unforeseeable damage!
Children, juveniles and persons not having been instructed in its usage are not permitted to operate this device and any air tools connected to it.
3.2 General safety information
When using this electric tool observe the following safety instructions, to exclude the risk of personal injury or material damage.
Please also observe the special safety instructions in the respective chapters.
Keep all documents, supplied with the device, for future reference.
Observe the statutory accident insurance institution regulations and regulations for the prevention of accidents pertaining to the operation of air compressors and air tools, where applicable.

General hazard!
Keep your work area tidy - a messy work area invites accidents.
Be alert. Know what you are doing. Set out to work with reason. Do not operate the electric tool while under the influence of drugs, alcohol or medication.
Consider environmental conditions. Keep work area well lighted.
Prevent adverse body positions. Ensure firm footing and keep your balance at all times.
Do not operate the electric tool near inflammable liquids or gases.
Keep bystanders, particularly children, out of the work area. Do not permit other persons to touch the tool or power cable while the electric tool is running.
Do not overload the electric tool - use it only within the performance range it was designed for (see Technical specifications).

Danger! Risk of electric shock!
Do not expose the electric tool to rain.
Do not operate the electric tool in damp or wet environment.
Prevent body contact with earthed objects such as radiators, pipes, cooking stoves or refrigerators when operating this electric tool.
Do not use the power cable for any purpose it is not intended for.
Risk of personal injury by escaping compressed air and parts hurled about by escaping air!
Never direct compressed air against persons or animals!
Ensure all air tools and accessories used are designed for the working pressure or are supplied via a pressure regulator.
Please note that, when disconnecting the quick coupler, the compressed air contained in the pressure hose will
escape all of a sudden. You should therefore hold the air hose firmly when disconnecting it.
Ensure all screwed connections are fully tightened at all times.
Do not attempt to repair the device yourself! Only trained specialists are permitted to service or repair compressors, pressure vessels and air tools.

Hazard generated by oil-saturated compressed air!
Use oil saturated compressed air only for air tools requiring such supply. Do not use an air hose used to supply compressed air containing oil to supply air tools not designed for operation on compressed air containing oil. Do not fill tires with compressed air containing oil.

Risk of burns from the sur- of parts carrying compressed
Let tool cool off before servicing.

Risk of personal injury and crushing by moving parts!
Do not operate the electric tool without installed guards.
Please note that the compressor will start automatically when the pressure falls off to minimum! - disconnect from power supply prior to any servicing.
Ensure that when turning ON (e.g. after servicing) no tools or loose parts are in the electric tool.

Hazard generated by insufficient personal protection gear!
Wear hearing protection.
Wear safety glasses.
Wear mask respirator when work generates dust or mist detrimental to health.
Wear suitable work clothes. When working outdoors wearing of non-slip shoes is recommended.

Hazard generated by electric tool defects!
Keep electric tool and accessories in good repair. Observe the maintenance instructions.
Priot to any use check the electric tool for possible damage: before using the electric tool carefully check safety devices, protection devices or slightly damaged parts for proper function as specified. Check to see that all moving parts work properly and do not jam. All parts must be correctly installed and meet all conditions necessary for the proper operation of the electric tool.
Damaged protection devices or parts must be repaired or replaced by an qualified specialist. Have damaged switches replaced by a service centre. Do not operate electric tool if the switch can not be turned ON or OFF.
Keep handles free of oil and grease.
3.3 Safety devices
Safety valve

The spring-loaded safety valve (19) is incorporated into the pressure switch. The safety valve opens if the max. permissible pressure is exceeded.
4. Operation
4.1 Prior to initial operation
Wheel installation
- Install the wheels as illustrated.

4.2 Mains connection
Danger! High voltage Operate device in dry environ-ment only.
Operate device only on a power source complying with the following requirements:
outlets properly installed, earthed and tested;
- fuse protection in accordance with the technical specifications.
Position power cable so it does not interfere with the work and is not damaged.
Always check to see that the device is switched OFF before plugging in.
Protect power cable from heat, aggressive liquids and sharp edges.
Use only extension cables with sufficient lead cross section (see "Technical Specifications").
Do not stop the compressor by unplugging, but switch OFF using the switch.
Unplug after use.
4.3 Generating compressed air
- Start device (22) and wait until the max. tank pressure is reached (compressor shuts off). The tank pressure is indicated by the tank pressure gauge (23).

- Set pressure regulator (20) to required working pressure. The current working pressure is indicated by the regulated pressure gauge (21).
Caution! The regulated pressure may not be set higher than the max. working pressure of the connected air tools!
- Connect air hose to compressed air outlet (24).
- Connect air tool. You are now ready to work with the air tool.
- Switch the compressor OFF, if you do not continue working immediately afterwards. Unplug after switching OFF.
5. Care and maintenance

Danger!
Prior to all servicing:
Switch Off.
- Unplug.
Wait until the device has come to a complete stop.
- Ensure the device and all air tools and accessories connected to it are relieved from pressure.
- Let the device and all air tools and accessories used cool off.
After all servicing:
- Check to see that all safety devices are operational.
- Make sure that no tools or other parts remain on or in the device.
Repair and maintenance work other than described in this section must only be carried out by qualified specialists.
5.1 Periodic maintenance
Prior to each use
- Check air hoses for damage, replace if necessary.
