Service Information - Scheppach Hc55Dc Profi Set Originalbetriebsanleitung

The compressor shall not be operated if the pressure
vessel is damaged or rusty. If you discover damage,
please contact the customer service workshop.
Instructions on the disposal of condensate:
Dispose of the condensate in accordance with local
and national environmental regulations. Ensure that it
is not discharged into the wastewater system.
10.3 Safety valve (Fig. 1, 3)
The safety valve (17) is set to the maximum permissible
pressure of the pressure vessel. It is not permitted to
adjust the safety valve or to remove the connection lock
(17.2) between the drain nut (17.1) and its cap (17.3).
Actuate the safety valve every 30 operating hours but
at least 3 times a year to ensure that it works when
required. Turn the perforated drain nut (17.1) anti-clock-
wise to open it, then pull the valve stem outwards by
hand via the perforated drain nut (17.1) to open the
safety valve outlet. Now, the valve audibly releases air.
Then turn the drain nut clockwise again to tighten.
10.4 Check the oil level at regular intervals (Fig. 11)
Place the compressor on a level and straight surface.
The oil level must be positioned between the MAX and
MIN of the oil sight glass (12).
Oil change: Recommended oil: SAE 15W 40 or equiv-
alent.
The original oil filling must be changed after 10 oper-
ating hours; afterwards the oil must be drained and
replaced with new oil after every 50 operating hours.
10.5 Changing oil (Fig. 1, 10, 11)
Switch the motor off and unplug the mains plug from
the power outlet. Remove the oil plug (15). After re-
leasing any air pressure, you can unscrew the oil drain
screw (12) on the compressor pump (13).
To prevent the oil from running out in an uncontrolled
manner, hold a small metal chute under the opening
and collect the oil in a vessel. If the oil does not drain
out completely, we recommend tilting the compressor
slightly. Once the oil has fully drained out, replace the
oil drain screw (12).
Dispose of the old oil at a drop-off point for old oil.
To fill in the correct quantity of oil, make sure that
the compressor stands on an even surface. Fill new
oil through the oil filling opening (18) until it comes up
to the maximum level. This is indicated by a red dot
26 | GB
on the oil sight glass (12) (Fig. 11). Do not exceed the
maximum filling quantity.
Overfilling the equipment may result in damage. Reinsert
the oil sealing plug (15) into the oil filling opening (18).
10.6 Cleaning the intake filter (Fig. 3, 12, 13)
The intake filter prevents dust and dirt being sucked
in. It is necessary to clean this filter at least every 300
operating hours. A blocked intake filter significantly re-
duces the compressor power.
Remove the intake filter (2x) by opening the screw (E).
Then pull off the filter cover (D). You can now remove
the air filter (F).
Carefully knock out the air filter, filter cover and filter
housing.
These components must then be blown out with com-
pressed air (approx. 3 bar) and reassembled in reverse
order.
10.7 Storage
m Attention!
Disconnect the mains plug, vent the device and all
connected compressed air tools. Store the com-
pressor in such a way that it cannot be used by un-
authorised persons.
m Attention!
Store the compressor only in dry locations that
are inaccessible for unauthorised persons. Do not
tilt the unit, only store it upright! Oil may leak out!
10.7.1 Releasing excess pressure
Release overpressure in the compressor by switching
off the compressor and using up the compressed air
still in the pressure vessel, e.g. with a compressed air
tool running at idle or with an air blow gun.
