Putting Into Operation - Scheppach ac 503d Traduction Du Manuel D'origine

Transport hangers
Insert the transport hanger (1 fig.1) on each side
into the sockets and secure them with 4 hex
socket head cap screws.
Wheels, Fig. 3
1. To fasten the wheels (12 fig 1), first guide
the wheel bolts (a) through the wheel (12),
followed by a socket (b) and a disk (c).
2. Slide the wheel unit through the lug under
the tank.
3. Attach this with a disk (e), a washer (f) and
a hex nut (g) and tighten these securely.
4. Repeat this procedure for the second
wheel.
Warning:
It is absolutely necessary to check the oil fill
level before the first use!
1 Make sure the place of setting up is clean,
dry, and well vented.
2 Make sure that the oil level is correct and
that the air filters are installed.
3
Start the compressor as described in the
chapter „Switching on and off the compres-
sor". At switching on for the first time, let the
compressor run for ten minutes at no load
with the drain valve open, so that all the
parts get well lubricated.

1 The pressure in the tank is controlled by the
pressure switch under the pressure switch
cover (2). When the maximum pressure set
is reached, the pressure switch is activated
and the motor switched off. The pressure is
reduced as the air is consumed by the
connected tool, until the minimum pres-
sure set is reached. Then the pressure
switch re-engages the motor. The operator
at the compressor should take care that
the motor engages and disengages dictated
by the influence of the increasing and
decreasing pressure in the tank. The motor
engages without any previous warning.
2 The maximum and minimum pressure have
been set in the works. These settings may
not be altered.
3 All accessories were connected to the
adjustable drain valve (6).
Warning: For any and all maintenance and
cleaning, please shut the engine off and
unplug the device.
Fig. 10 and 11
1 Following the first ten hours of operation,
empty the oil from the crankcase and refill
it with clean oil. To this end, remove the
sealing plug on the crankcase (at the bot-
tom left of the crankcase).
Attention: SAE 30 or L-DAB 100 above
10 °C,
SAE 10 or L-DAB 68 below 10 °C.
2 After every 500 operating hours, drain the
oil and fill the crank box with clean oil.
3 After every operating day, drain the con-
densate from the tank using the drain plug
(11).
Assembly
Rubber Bumper, Figure 4
Secure the rubber bumper on the bracket on the
front side of the tank. Use the enclosed screws,
washers, and nuts.
Oil, Figure 5
Warning: It is imperative that you check the
oil level before using the machine for the
first time!
Operation of the machine without oil will cause
irreparable damage and invalidate the guaran-
tee.
1 Remove the plastic oil filler plug located in
the crank box of the compressor housing.
2 Fill the crankcase with oil, until the oil level
in the oil-level indicator (16) reaches the
centre of the circular marking.

Putting into operation

Warning: As compressed air comes off the out-
put, the output may not be directed towards the
operator or people in the vicinity. The air coming
off the exit may not be inhaled. Daily check the
pressure control valve.
Switching on and off the compressor, Fig. 7
1
Check the model plate on the compressor:
230 – 240 V (or 110 – 120 V).
2 Plug the compressor cable into a standard
socket (240 V or 120 V) and switch the
compressor on.
Operation
4 As shown on the adjustable output pressure
gauge (4), the pressure of the adjustable
exit can be altered by turning the adjustable
button (5).
Attention: In order to read the correct output
at the output gauge, air must flow through the
output. The adjustable valve must be set and the
pressure gauge read with the valve open, while
the air flows from the output set through the
accessory.
Turn the pressure regulator clockwise to increa-
se the air pressure. Turn the pressure regulator
anticlockwise to reduce the air pressure.
Attention: The absence of air flow during set-
ting produces an incorrect display. For a correct
display, air must flow.
5 Upon termination of your work, or when you
leave the compressor unattended, switch it
off as follows:
• Press the ON/OFF switch (3).
Maintenance
4 Check the air filter cartridges inside regu-
larly. Remove the air filter cover (A) from
the housing by turning it slightly and clean
the filter (B). After cleaning the filter, re-
insert it and close the cover.
Caution! Never operate the compressor
without air filter.
5 Before every startup of the machine,
check the functioning of the safety valve.
When checking, the tank must read at near-
ly maximum pressure.
For checking the valve, set the tank under
pressure and pull the ring on the safety valve to
the outside.
There should be air escaping from the valve.
At releasing the ring from the safety valve, the
escaping air must stop.

3 Close the opening using the sealing plug
(14) included in the delivery.
Air filter, Fig. 6
Warning: Both air filters must be mounted
before the first use. Operation without air filters
damages the compressor and the warranty will
lapse.
Both air filters (15) are screwed in and tightened
at the top of the cylinder heads.
Attention! Please remove the plastic cap
before you screwing the air filters in the
cylinder head.
3 For switching the compressor on, lift the
ON/OFF switch (3) on the pressure switch
cover (2).
4 For switching the compressor off, depress
the ON/OFF switch.
• Wait until the compressed air has escaped
via the drain valve under the switch cover
(2).
Attention: On pressing the button you should
hear a short air exit (about half a second).
Fig. 9
• Switch the machine off and pull the mains
plug.
• Pull the ring on the safety valve (8) in
order to make sure that the compressed air
has escaped from the tank, or open the
drain plug of the tank in order to let the
pressure escape.
Warnings
For this test goggles must be worn. Do not hold
your face close to the safety valve as there the
air escapes at a high pressure.
Should the safety valve not work properly as
described above, immediately switch off the
compressor and have the safety valve examined
by your dealer.
Do not work with the compressor when the sa-
fety valve does not work properly, as described
above.
