Electrical Connection; Installation And Use - Michelin MB 3100 U Bedienungs- Und Wartungshandbuch

21. NEVER USE A COMPRESSOR WHICH IS DEFECTIVE
OR OPERATING ABNORMALLY
If the compressor appears to be operating unusually, making
strange noises, or otherwise appears defective, stop using it im-
mediately and arrange for repairs by an authorized service center.
22. DO NOT WIPE PLASTIC PARTS WITH SOLVENT
Solvents such as gasoline, thinner, benzene, carbon tetrachlori-
de, and alcohol may damage and crack plastic parts. Do not wipe
them with such solvents. Wipe plastic parts with a soft cloth lightly
dampened with soapy water and dry thoroughly.
23. USE ONLY GENUINE REPLACEMENT PARTS
Replacement parts which are not original may void your war-
ranty and can lead to malfunction and resulting injuries. Genuine
parts are available from your dealer.
24. DO NOT MODIFY THE COMPRESSOR
Do not modify the compressor. Always contact the authorized
service center for any repairs. Unauthorized modification may not
only impair the compressor performance but may also result in
accident or injury to repair personnel who do not have the re-
quired knowledge and technical expertise to perform the repair
operations correctly.
25. TURN OFF THE PRESSURE SWITCH WHEN THE COM-
PRESSOR IS NOT IN USE
When the compressor is not used, turn the knob of the pressure
switch OFF, disconnect it from the power source and open the
drain cock to discharge the compressed air from the air tank.
26. NEVER TOUCH HOT SURFACES
To reduce the risk of burns, do not touch tubes, heads, motors
and cylinder.
27. DO NOT DIRECT AIR STREAM AT BODY
Risk of injury, do not direct air stream at persons or animals.
28. DRAIN TANK
Drain tank daily or after 4 hours of use. Open drain fitting and tilt
compressor to empty accumulated water.
29. DO NOT STOP COMPRESSOR BY PULLING OUT THE
PLUG
Use the "AUTO/OFF" knob of pressure switch.
30. USE ONLY RECOMMENDED AIR HANDLING PARTS AC-
CEPTABLE FOR PRESSURE NOT LESS THAN 125 PSI (8.6
BAR)
Risk of bursting. Use only recommended air handling parts ac-
ceptable for pressures not less than 125 psi (8.6 bar).
INTENDED USE
This compressor has been designed for DIY use with intermit-
tent (not continuous) operation. The use of the compressor for
more than 20 min. during one hour is not recommended.

ELECTRICaL CONNECTION

The compressor should be grounded while in use to protect the
operator from electric shock. The compressor is equipped with a
three-core cable and three-pin grounding type plug to fit the pro-
per grounding type socket. Never disassemble the compressor or
carry out other connections to the pressure switch.
WARNING – the grounding must be carried out according to EN
60204 norms.
USE OF EXTENSION CaBLE
Use only three-way extension cables that have three-pin con-
necting plugs and three-pole sockets that accept the compressor
plug.
Do not use extension cables that are damaged or squashed. An
under-rated cable will cause a drop in line voltage resulting in loss
of power and overheating.
The table shows the correct size to use depending on the length
according to the following parameters :

Avoid electrical shock hazard. Never use this compressor with
a damaged or frayed electrical cord or extension cord. Inspect all
electrical cords regularly.
Never use in or near water or in any environment where electric
shocks are possible.

INSTALLATION AND USE

Fit rubber feet underneath the base of the unit as indicate (if not
assembele).
Position the compressor on a flat surface or one with a max.
inclination of 10° in a well-ventilated area. If the surface is sloping
and smooth, make sure that the compressor does not move while
in operation.
If the compressor operates on a shelf or the edge of a stand,
ensure that it may not fall off by securing it appropriately.
Ensure that the knob situated in the upper part of the compres-
sor is turned to "0". Put the plug into the power socket and turn
the knob to "I".
Attach the rubber hose or the spiral type hose to the appropriate
fitting situated near the pressure switch.
The compressor operates completely automatically and is con-
trolled by the pressure switch which stops it when the pressure
inside the tank reaches the maximum pressure and starts it again
when the pressure returns to the minimum level. The difference in
pressure is usually 2 bar (29 PSI).
After having connnected the compressor to the electrical power
supply line, load to the maximum pressure and check the correct
efficiency of the machine.
aDJUSTING THE WORKING PRESSURE
It is not always necessary to use the maximum working pressu-
re. On the contrary, a pneumatic tool usually requires less pres-
sure. Adjust the pressure to the required level by turning the knob
clockwise to increase it and anti-clockwise to decrease it. The
pressure setting is shown on the pressure gauge of the compres-
sor.
