Î Remove the oil dip one more time and
check the oil level.
The oil level is correct if it is within the markings (arrows) on the oil dip.
Î If the oil level is below the bottom mark,
open the filler neck lid (arrow) and add
fresh motor oil.
Î Wait five minutes, until the oil has col-
lected in the oil pan.
Î Check the oil level as described above.
Î Repeat this procedure as often as nec-
essary until the oil level is between the
markings on the oil dip.
Î After the check, insert the oil dip and
close the lid of the filler neck.

Check the coolant and refill
Note
Prior to every operation, the fill level of the
coolant in the equalisation container must
be checked.
Caution
Observe the brand of antifreeze used. The
mixture can cause a chemcial reaction and
hazardous substances can be generated.
Do not mix different antifreeze types.
몇 Warning
The motor can overheat if there is a lack of
coolant. Turn the motor off immediately and
let it cool down.
If the motor is so overheated, that water vapors escape, immediately turn the motor off
and keep a safety distance to the motor until the pressure has decreased.
Danger of burns! Never open the lid on the
cooler while the motor has operating temperature. The container is under pressure.
Î Open the lid on the equalisation con-
tainer of the motor coolant, fill in fresh
clean water and the required antifreeze.
Cleaning/replacing the air filter
Î Open both locks (arrows) on the lid.
Î Remove the lid and the dust sediments.
Î Take out the filter inlay.
Î Blow out the filter insert with com-
pressed air (max. 2 bar) from the inside.
Î Clean the inside of the air filter housing
with a cloth.
Note
Severely contaminated or defective filter inserts must always be replaced.
Î Please the filter insert into the air filter
housing with the closed side facing out.
Note
Make sure the lid fights snugly, if the lid
does not close properly, dust can get into
the combustion chamber of the motor and
damage it.
Î Replace the lid and close the locks.
Draining the compressed air system
Note
The compressed air system must be
drained in regular intervals.
During continuous operation, it might be
necessary to drain it 2 to 3 times a day.
Note
Do not drain the liquid from the system during high pressure operation. If the ball tap is
open, pressure cannot be built up in the
compressed air lines.
Î Open the ball tap. Allow the water to
drain.
Î After the drain procedure, close the ball
tap.
Compressor
Note
Maintenance work on the compressor may
only be performed by the authorised customer service.
