Not all of the accessories illustrated or described are in-

The machine is designed for generating compressed
atmospheric air for commercial and industrial pur-
poses, i. e. for use as working air for driving tools,
as blowing air, e.g. for painting, or as control air for
plants and equipment.
For damage caused by usage other then intended,
the user is responsible.
– The intake air must be free from any aggressive
or inflammable particles.
– Before each operation, check the oil level using
the oil dip stick and, if necessary, replenish.
– It´s alway preferable to have longer air pipe,
than using extention cables, especially for models
K 290/K 410.
– Extension cables of up to 25 m in length must
have a cross-section of 1.5 mm2. Any lengths be-
yond this require 2.5 mm2. If the cross-section of
the conductor is too small, this will cause a volt-
age drop and there is no guarantee that the mo-
tor will start correctly. Cable reels must be fully
unwound.
– Never pull out the mains plug while the motor is
running. If the mains voltage fails, switch the ma-
chine off using the On/Off switch 1 and when
the voltage has been restored, switch on again.
– Do not exceed the maximum delivery output of
the machine (20 switchings per hour). At over-
load the pressure switch 7 is actuated. The ma-
chine is utilised optimally with a pause/operation
time ratio of 1 : 3.
The Würth machines of model series K 210, K 290
and K 410 are compressors with drive motors flang-
ed directly onto the compressor. Fresh air is drawn
in via the intake filter 4 serving as a sound absorber,
and compressed in the cylinder. The compressor
valve integrated in the cylinder head controls the
suction and emission of the air. The compressed air
flows into the compressed air reservoir via the pres-
sure lead 2 and the non-return valve 16.
The compressor functions in intermittent operation.
Upon reaching the maximum pressure the pressure
switch 7 switches the compressor off and when the
pressure falls to approx. 8 bar (for the K 210 ap-
prox. 6 bar) switches it on again.

Always use the correct supply voltage: The power
supply voltage must match the information quoted
on the tool identification plate. Tools with a rating of
230 V can also be connected to a 220 V supply.
Check the oil level on the oil dip-stick.
Installation
Install your compressor in a horizontal position in a
cool, dry, place exposed to as little dust as possible.
The maximum permissible angle of tilt is 15°. Pay spe-
cial attention to good cooling of the plant. This is main-
ly achieved by ensuring a free passage of fresh air.
It is important that the temperature at the location
does not fall below +5 °C and does not exceed
+40 °C. Devices and leads that give off heat should
be avoided in the environment.
Compressed air connection
– Connect the compressed air lead to the reduced
quick coupling 11.
– Loosen the locking ring on the pressure reducer
21 and set the required working pressure on the
turning grip:
– clockwise turn: working pressure increases,
– anti-clockwise turn: working pressure decreases.
– The following reference values apply for different
kinds of work:
Paint-spraying devices........................2 - 4 bar
Drive for pneumatic tools ....................5 - 7 bar
– Observe the information in the operating instruc-
tions of the consumers used.
– Secure the pressure reducer against unintention-
al alteration using the locking ring (or snap
switch).
– After use set the pressure reducer 21 back to “0”.
– All Models are equipped with an additional
quick coupling (not reduced) 12. Before connect-
ing more than one pneumatic tool to the com-
pressor, please check that the total air consump-
tion won´t be higher than the „effective delivery
quantity“ contemporary use of more than one
tool is not suggested.
Switching on
– Switch the compressor on using the On/Off
switch 1.
– The compressor is fitted with an automatic pres-
sure relief. If the rated pressure in the compressed
air reservoir 17 reaches 10 bar (for the K 210
8 bar), the motor is automatically switched off
and the pressure lead 2 between the compressor
and non-return valve 16 is vented. A pressure-
free re-start of the compressor is thereby guaran-
teed.
The pressure relief will cease to function if the
mains voltage fails during operation, or if the
mains plug is disconnected. The pressure relief
becomes effective again, however, if the com-
pressor on the pressure reducer 21 is set to “0”.
Switching off
– Switch the compressor off using the On/Off
switch 1.
Before commencing any work on the machi-
ne, discharge the air from the reservoir and
switch the machine off.
Always keep the machine clean.
Suction filter 4
Remove the filter and wash the sponge element with
a neutral detergent rinse and dry it carefully. If the
sponge element is damaged, replace it with a new
one.
Do not operate compressor without suction fil-
ter.

Draining the condensation
– Caution! The compressed air reservoir 17 is un-
der pressure. Place a collecting vessel under-
neath. Carefully open the condensation water
drain cock 19 on the base of the compressed air
reservoir by making a 1/2 turn and drain the
condensation.
– Check the condensation level regularly in the
transparent container of the pressure reducer 21.
It must not exceed the upper marking. For drain-
ing the condensation, the knob located on the un-
derside of the pressure reducer must be opened
a 1/2 turn under pressure.
Oil change (except oil free)
– As a basic rule the oil change should be carried
out under hot-running conditions.
– Place the collecting vessel underneath and open
the oil drain plug 10. Caution! Danger of burn-
ing from the hot oil!
– Close the oil drain plug 10 and fill up with oil of
class ISO 100 through the oil filler opening 9.
Never mix different oils.
Maintenance intervals
If the machine should fail despite the care taken in
manufacturing and testing, repair should be carried
out by a Würth MasterSERVICE agent.
