This equipment:
has hot, electric parts;
when connected to electric power, it may turn on or turn off automatically due to tank's
pressure or to the tripping of electric protection elements;
may cause mechanical or electric interferences in nearby equipment;
must not work in places where non authorized people, children or animals may have access;
requires an authorized person to supervise its use and maintenance as well as the use of
adequate individual protection equipment;
must be installed and operated in well ventilated areas and protected against humidity or
water leakage.

WARNING
Whenever an electric product is used, certain basic safety precautions must
be followed in order to avoid fire, electrical shock, and personal damage
hazards.

2. Never exceed the maximum pressure indicated in the compressor's identification tag/sticker.
Do not change the pressure switch safety valve factory adjustment. If any adjustment to the pressure
switch is needed, contact us at

Never weld or carry out maintenance jobs on the tank, once they may affect its resistance or
may hide more serious problems. In case of leakage, cracks or deterioration caused by
corrosion, stop using the equipment immediately and get in touch with the
4.

Never run the tank above the maximum pressure indicated on its identification tag.5.
6. In case of an inspection, the user of this product must keep the pressure vase book provided by
the manufacturer available, attached to the other safety documents required by NR-13 of Labor
Ministry of Brazil, for as long as the vase is used, until it is disposed of. The final user must
follow the resolutions set forth in NR-13 as to the installation, maintenance, and operation of the
pressure vase (compressed air receiver). The useful life of a pressure vase depends on several
factors that do contribute to determine it. This aspect must be monitored and established by a
certified professional, according to NR-13. Remark: The hydrostatic test carried out during the
product manufacturing does not replace the initial inspection, which must be carried out at the
location where the product is installed, duly followed up by a certified professional, according
to NR-13 Mtb. Schulz S.A., manufacturer of the product, declares that the local legislation and
inspection rule upon the above provided information, and that all prudent, preventive, and wise
safety procedures must prevail.
7. Air compression is a heat generating process and parts and accessories are subject to
high temperatures. Therefore, one must be careful when handling them in order to avoid
burns.

8. The produced compressed air is not adequate for human consumption, because it
has harmful substances. To use it for this purpose, it is necessary to install special
filters. Please contact us at for additional information.

Do not carry out any maintenance while the compressor is on. Do not clean or touch the
electric components without unplugging the compressor from the outlet.
The refrigeration air intake protecting screen must be always clean to prevent the propeller from
pulling in impurities.
Never clean the compressor's external surface with solvent (thinner). Always use neutral
detergent.
Avoid the accumulation of solvents, paints or other chemicals that may cause damage or
explosion risk to the compressor.
Always use an electric extension cord according to specifications (see Table 2 - page 9)
which must not be amended. If these recommendations are not followed, the user may be
injured and the compressor's electric components may be damaged, violating the
warranty. When necessary, use a longer air hose.
If the equipment presents any irregularities, stop its use immediately and contact us at
Do not remove any air receiver part under pressure.

For this compressor: after removing it from its package, assemble (when it does not came fixed)
the rubber feet (Figure 6).
2. Location:
2.1 Compressor's installation:
3. Position:
4. Quality of compressed air:
5. Electrical connection:
5.1
Install the compressor in a covered, well ventilated area, free of dust, gases, toxic gases,
humidity or any other kind of pollution. The ambient temperature recommended during work is:
minimum of 5 C (41 F) and maximum of 40 C (104 F). In order to avoid damage to the compressor,
operate it on a level foundation.
When this compressor model is coupled to a compressed air
network, the connection must be made by a hose or expandable joints so that the charges, thermal
expansion, piping's weight, mechanical and thermal shocks or obstructions are not transmitted to
the tank. The tank may be damaged if these warnings are not observed.
Keep a minimum distance of 800 mm (32 inch) from any obstacle, to allow good
ventilation during operation and to make maintenance easier.
For services in which the air must be free of dust particles, the
installation of special air filters. Please contact us at for information.
Look for a specialized technician to evaluate the electrical supply and to select the adequate
protection and input devices. (Installation conform Figure 7)

The incorrect installation of the grounding wire connector may result in an electric shock. If it
is necessary to replace or repair both the cable and the connector, do not connect the
grounding wire to the terminal of the flat blade. The green cable, with or without yellow
stripes, is the grounding cable. In case of doubts regarding the grounding information or
whether the product is properly grounded, make sure you contact a qualified electrician to
verify the connections.
6. Important:

A compressor with good use (with pressure switch) will have roughly six (6) starts per
hour. (See instruction Troubleshooting Tips - page 13)

The electric motor warranty will only be granted if the installation
instruction are followed according to diagram (Figure 7 - page 8).

START UP PROCEDURE
This equipment is tested, in the factory.
After the arrangements regarding location, the pressure vase adequacy to local Technical Norms and
Legislation, electric network, the electric outlet to connect 2P+GR plug, electric switch and (customer's

Note:
-
Open the pressure regulator (valve) to completely exhaust the air receiver and close it afterwards.
Your compressor is now ready to operate. Connect it to the air distribution network or
hose and start the electric motor. When the compressor reaches maximum pressure, open the
pressure regulator (valve) so that the air can flow to the distribution network or hose. Check if
there is any leakage along the tubing, by using a water and soap lather.
The initial start procedure must be repeated whenever maintenance occurs.

Completely open the pressure regulator (valve) .
Turn pressure switch lever to ON position (Figure 11).
Let the compressor run for about ten (10) minutes to allow a homogeneous lubrication of the moving
parts.
Fully close the pressure regulator (valve) , so that the compressor can fill up the tank. Compressor
will automatically turn OFF(through the pressure switch - See Figure 10), when the pressure gauge
shows maximum pressure respectively around 120 psi (8.3 bar).

Open the pressure regulator (valve) to discharge the compressed air from the tank and this will
decrease the internal pressure in the compressor. The compressor will automatically re-start (through
the pressure switch) when the pressure gauge registers 80 psi (5.5 bar).
Close the pressure regulator (valve) and unplug the equipment through the lever to the OFF position
(Figure 11 ).
Verify if ASME safety valve (Figure 9) is working.
Open drain petcock (Figure 10) to exhaust the tank's condensed water and quickly close it.
Attention: The tank's maximum pressure when drained must be 10 psi (0.7 bar).
OPERATION
OPERATION
Attach hose, then add chuck or other tool to open end hose. Plug in wire (power cord). Turn pressure
switch lever to auto position. When full pressure is reached turn pressure regulator (valve) knob
clockwise until desired outlet pressure is achieved (Figure 12, page 11).
