If defective, have it repaired or replaced in a customer service centre. Make sure that the outside of the compressor does not show any visible damage. If so, please contact the nearest customer service centre.

13. Outdoor use
    If the compressor is used outdoors, extension cables for outdoor use with appropriate marking may only be used. Caution: adequate cable cross-section (at least 1.52 mm) must be used; there may be problems with the appliance starting when cables of more than 10 m are used at unfavourable temperatures.

14. Attention
    Work carefully and cautiously. Do not use the compressor if you are tired. If the compressor cannot be used under the influence of alcohol, drugs or pharmaceuticals that may be the cause of tiredness.

15. Check the components for defects or untightness
    If any protective equipment or other parts of the compressor have been damaged, it is necessary to check it before putting the appliance into operation again and make sure that the operation will be reliable. Check the direction adjustment of the moving parts, lines, pressure control valve, compressed air connections and all other construction elements important for common operation of the compressor. Any damaged parts must be repaired or replaced in a service shop or as specified in the Operating Instructions.

Do not use the compressor if the pressure sensor is defective.

1. Use the compressor only for works mentioned in these Operating Instructions
   A compressor is an appliance producing compressed air. Never use the compressor for works not mentioned in these Operating Instructions.

    Do not touch the lines, engine and other hot parts of the compressor as you could face a risk of burn.

Emergency Action

Apply the first aid adequate to the injury and get qualified medical assistance as quickly as possible. Protect the injured person from more accidents and calm him/her down. For the sake of eventual accident, in accordance with DIN 13164, a workplace has to be fitted with a first-aid kit. It is essential to replace any used material in the first-aid kit immediately after it has been used. If you seek help, state the following pieces of information:

1. Accident site
2. Accident type
3. Number of injured persons
4. Injury type(s)

Disposal
Disposal instructions are illustrated in the form of pictograms on the device or packaging. Description of the pictograms is given in “Identification” chapter. Disposal of transport packaging Packaging protects the device against damage during transport. Packaging materials are usually selected according to their effect on environment and disposal methods and can therefore be recycled. Returning of the packaging back to circulation saves resources and costs for packaging disposal. Parts of the packaging (e.g. foil, styropor) may be dangerous for children. Risk of suffocation! Keep these parts of the packaging out of reach of children and dispose as soon as possible

Operator requirements

The operator must carefully read the Operating Instructions before using the appliance.
Qualification
No special qualification is necessary for using the appliance
apart from detailed instruction by an expert.
Minimum age
The appliance can only be operated by persons over 18 years of age. An exception includes youngsters operating the appliance within their professional education to achieve necessary skills under trainer’s supervision.

Technical specifications

Transport and storing

The appliances are mobile and can practically be used everywhere. If the compressor is wall-mounted, the minimum distance of 30 cm must be kept to ensure appropriate cooling. Appliances must necessarily be transported in a vertical position; otherwise, oil will run out of the air hole of the engine case. Prevent any hits to fittings.

Residual risks and protective measures

Electrical residual risks:

1. Direct electrical contact:
   Risk of electric shock
   To be used in electrical networks with a safety switch
   against stray current (RCD-FI 30 mA) only.

2. Indirect electrical contact:
   Risk of electric shock
   To be used in electrical networks with a safety switch
   against stray current (RCD-FI 30 mA) only.

Thermal residual risks:

1. Burns, chilblains:
   Contact with the cylinder head and pressure lines
   may cause burns.
   Avoid both of these construction elements.

Exposure to noise:

1. Hearing damage:
   Long stay in the immediate vicinity of the appliance
   may damage hearing.
   Wear headphones.

Neglecting the ergonomic principles:

1. Human behavior / erroneous behavior:
   A compressed air current may lead to serious injuries.
   Never hold the current in body holes.
   Compressed air may cause tanks and tires to break.
   Do not exceed the max. filling size.

Installation and first start-up

Pic.2+3+4:

1.  Remove the oil tank transport protection (if applicable) pic. 3
2. Insert the attached oil gauge or plug instead.
3. Oil gauges or plugs, pic. 4 (failing to do so will increase pressure in the engine case and oil will spirt).

Electrical connection; grounded connections to be used only:

• 230 V appliances are supplied with plugs fitted with a ground contact

Pic. 5
The following must be considered as far as 230 V appliances are concerned:
If a too long extension cable with a too small cross-section is used, voltage will drop, which may result in a more difficult starting and increased engine load. If possible, we recommend connecting the engine cable directly to the outlet and using longer air hoses (another measure: see the winter operation).

Recommended cable cross-section values for all 230 V appliances:

• Length within app. 10 m = 1.52 mm
• Length within app. 20 m = 2.52 mm

Oil level check (for oil compressors only):
Oil may leak when the appliance is transported. Please check the oil level on the aperture or using an oil gauge (more information at a similar description with a picture)

Winter operation of compressors

The following must be considered in colder seasons when operating the compressors: Oil gets thickened and its viscosity increases with low temperatures in the engine case. This makes first appliance starting before warm-up more difficult. Proceed as follows when facing difficulties:

1. Reduce any pressure in the air jet to zero.

2. Open the drainage screw on the bottom part of the air jet.

3. Unless being absolutely necessary, do not use any
   extension cable!

4. Switch on the compressor and let it run (without any extension cable). With the drainage screw open, let it run for app. 2-3 minutes to enable air to leak and thus pressure to reduce. The appliance will warm in these 2-3 minutes to enable further operation.

5. After 2-3 minutes, close the drainage screw. The air jet can now be filled and pressure increased.

6.  Change oil – use 5W40 synthetic oil for light running or, as alternative, SAE 80 gearbox oil.

7. If the compressor does not start despite all the effort, put it out of operation for half an hour to one hour in a tempered room to warm up.

8. Please contact the customer service centre for more difficulties.

All documents necessary for proper operation are included in the supply (see the simple regulation for pressure vessels). When used for industrial purposes, an inspection is necessary before the appliance is used for the first time under the operating safety regulation.

Safety instructions for first start-up

Procedure

Switching compressors on and off:
The On/Off button (rotary and pull switch) is up on the pressure switch cover at all compressors. Switch positions are marked as “0” and “I”. When plugging, the switch must be in the “0” position, then the appliance may be started. When switching the appliance off, put the switch to the “0” position first and then unplug the compressor. Never switch the appliance off by unplugging as this would prevent depressurizing.

Caution: Empty the condensate at regular intervals (monthly) (see the drainage screw).

Operation

1. Using pneumatic tools and devices
   Please follow the air consumption information of manufacturers. Check whether the power of your compressor is enough to operate the given device. The air consumption table details may be used as benchmark values.

2. Servicing and maintenance
   Check regularly the oil level and add some if necessary. Clean the air filter if dirty; wash the filter inserts in a detergent – do not use thinners or solvents. If necessary, order new inserts from the customer service centre.

3. Air jet drainage:
   Regardless of the type of compressor, the drain valve is placed on the bottom part of the air jet at all compressors. Drain only if the air jet is under pressure.

4. Opening the drain valve:
   Unscrew the screw closure to such extent the air deflates. Any accumulated water is blown out with the air.

5. Rusty water:
   Rusty water may run out when the air jet is initially drained. Rusty water is caused by clips fallen to the tank when producing air jet and disintegrated subsequently. This is quite normal and water gets clearer after several drains.

Oil filler neck and oil level checking (for oil compressors)
At appliances fitted with an oil gauge (1), add oil after removing the gauge (1) to the appropriate hole (2) and check the level using the gauge marking. At appliances with an aperture and marking in the glass, remove the oil filler neck and add oil up to the aperture marking. If the aperture has no marking, 2 3rd – 3 4th filling of the aperture is appropriate. The oil drainage screw is always on the side or bottom part of the engine case.

Air fitting and clack valve
Pic. 6

1. Air fitting (2): Air ducting (2) at all compressors is connected using a quick-acting coupling. Both reduced pressure and complete pressure from the air jet may be drawn.
2. Clack valve: The clack valve is located at the end of the main air ducting, at the air input to the air jet. The connection point is different for various types of compressors. Ducting goes from this valve to the valve to make starting easier.
3.  Pressure-relief valve: Depending on the compressor type, it is located on the pressure switch (4), on the pressure control valve or on the air jet. The pressure-relief valve responses to any malfunction of the pressure switch (4) and thus limits the pressure in the air jet to the max. cut-off pressure + 1 bar!
4. Pressure control valve (1): To set the currently needed pressure, please press the regulator up and set the requested pressure + 1 bar on the air gauge. To lock the pressure control valve (1), press the regulator down again. If necessary, provide additional regulation after the first operating cycle in the same way.

Safety instructions for the operator

• Use the appliance only after careful reading and understanding of the Operating Instructions.
• Please follow all safety instructions specified in the Operating Instructions.
• Behave responsibly towards other persons.

Inspections and servicing
IMPORTANT: After app. half an hour to one hour of operation, please check the cylinder head screws and tighten them if necessary. Torque: max. 10 – 20 Nm/by hand force. Later: cylinder head screws and all other screwed connections on should be checked every 200 – 300 operating hours and tightened if necessary.
Servicing
Clean the filter on the suction side if dirty or replace it. After operating the appliance for some time, the condensate must be emptied by opening the drain valve on the air jet. IN case of continuous operation, this should be done every 4-6 weeks. If the appliance is used for short works, empty the condensate once in 3 months. Belt tension at compressors with a V-belt must be checked at regular intervals (every 4-6 weeks).

Oil level check and oil change
The appropriate oil level may be checked on the oil aperture (if applicable) or on the oil gauge.Maximum level = a small bubble or the upper marking on the oil gauge must be seen in the aperture. Minimum level = oil must not get under the red point in the middle of the aperture or the lower marking on the oil gauge. Specified oil = universal oil – 15 W 40 (100 operating hours) or Güde 5W40 compressor oil, Art. No. 40056 (300-500 operating hours)
Oil change:
After running in, i.e. after 100 operating hours, oil should be changed for the first time. Another oil change after app. 300 – 500 operating hours.
Oil adding: unscrew the filler neck and add oil using a funnel.
Oil drainage: Unscrew the drain screw and let oil run out.

Air filter:
Check the air filter app. once a quarter. Foam filters are washed with a detergent. Replace the filter if heavily contaminated with paint or varnish! Folded filters to be blown by compressed air or replaced if necessary; not to be washed!
CAUTION:
If more oil is added than the maximum level, spring-energised seals may get untight. The surplus oil along with the compressed air will shortly get to the air jet – more oil is thus consumed – until reaching the common state. If oil does not reach the minimum level (red point in the aperture or lower marking on the oil gauge), consequential damages such as seizure of bearings, connecting rod, piston pin, crankshaft or piston seizing must be counted with.
CAUTION:
The air hole of the engine case is located in the oil filler neck (No. 1 or 3). Air is commonly slightly blown in this place when the appliance is operated, which is normal. Excess pressure in the engine case caused by the movement of pistons, which results in oil leaking in that place is also normal (to be wiped occasionally). The claim arising from the warranty will not apply in case of consequential damages as a result of the failure to meet the above- mentioned!!!

Safety instructions for inspections and servicing

Only a regularly serviced and treated appliance may be a satisfactory aid. Inadequate servicing and maintenance may lead to unexpected accidents and injuries.

Inspections and servicing schedule

Weekly:

• Condensate emptying

Monthly:

• Oil level check (e.g. SAE 5W40)
• Safety valve check
• Belt tension check
• Oil leak check
• Air filter cleaning

Every 500 operating hours:

• Air filter insert replacement

Every 1,000 operating hours:

• Complete cleaning
• Complete oil change (e.g. SAE 5W40)
• V-belt and pulley check
• Line check
• Power line check

Air consumption of pneumatic appliances/directions for use
Not the electric motor power but the produced air volume (actual power) is decisive for the compressor power. Actual power = suction power minus app. 35-40% of the power (for each compressor, regardless of the manufacturer). Do not choose too small compressor power in order not to load it up to the upper limit and to have some reserve for the attached appliances. The air jet size (capacity in litres) may not be decisive. However, capacity, on the other hand, should not be too small to ensure there is air supply and the compressor could also cover higher needs in the short term. If provisions of the generally applicable regulations and these Operating Instructions are not adhered to, the manufacturer cannot be held liable for any damage.

The above-mentioned values are just of orientation nature as they may differ for appliances of various manufacturers. Works with higher air requirement may also conditionally be performed with compressors with a lower suction power than the requirement given in the table. If pressure is reduced in the air jet under the necessary operating pressure, however, an appropriate break must be introduced after the air jet is pressurised again. In order not to load the compressor when being operated by more than can be tolerated, we recommend taking into account some power reserve when selecting the right appliance.

Failures – Causes – Remedy

CAUTION: FUSES AGAINST OVERHEATING MUST FIRST BE CHECKED!
