OIL BREATHER
• For transportation purposes the oil breather is supplied in a separate bag.
• Read the caution plate and take off the plastic bung from the crankcase, add oil and then assembly the oil breather.
• The plastic bung should be retained for future use should it be necessary to transport the unit.
WARNING:
Never operate the compressor with only the plastic transportation bung tted. Under normal use internal pressure can expel the bung along with
oil from the head, possibly leading to damage.
PLEASE NOTE THE FOLLOWING PHOTOGRAPHS & INSTRUCTIONS ARE FOR REFERENCE ONLY AND MAY DIFFER FOR YOUR
COMPRESSOR MODEL. PLEASE CONTACT JEFFERSON TOOLS IF YOU NEED ANY ADVICE ON THE ASSEMBLY PROCEDURE.
Position the compressor on a at surface or with a maximum permissible inclina-
tion of 10° (Fig.3), in a well aired place, protected against atmospheric agents and
not in a place subject to explosion hazard. If the surface is inclined and smooth,
check if the compressor moves while in operation – if it does, secure the wheels
with two wedges.
If the surface is a bracket or a shelf top, make sure it cannot fall, securing it in a
suitable way.
To ensure good ventilation and efcient cooling, the compressor’s belt guard must
be at least 100 cm from any wall (Fig. 4). Compressors tted on the tank, with
xed feet, should not be rigidly secured to the ground and tted with 4
anti-vibration supports.
Ensure that the compressor is transported correctly, do not overturn it or lift it with
hooks or ropes (Fig. 5- 6)

GROUNDING INSTRUCTIONS
WARNING: This appliance must be earthed. A plug with bare exible wires exposed is hazardous if engaged in live power socket outlet.
To eliminate the possibility of an electric shock your machine has been tted with a CE approved, non re-wireable moulded plug and cable which
incorporates a fuse, the value of which is indicated on the pin face of the plug. If the plug is marked with the symbol and the fuse needs replacing,
a CE approved fuse must be used of the same specied amp rating. The fuse cover is detachable, never use the plug with the cover omitted. If a
replacement fuse cover is required, ensure it is the same colour as that visible in the pin face of the plug (i.e.red). If the tted plug is not suitable, it
should be cut off and destroyed. The end of the cable should now be suitably prepared and the correct type of plug tted.
EXTENSION CORDS
IMPORTANT:
On product exceeding 2000W it is recommended that the power cable and/or extension cable are fully unwound before a connection is made to
the power supply. However, ensure the residual cable dose not pose a trip hazard. Use only extension cords that have three-prong grounding type
plugs and three-pole receptacles that accept the compressor’s plug. Replace or repair any damaged cords. Make sure your extension cord is in
good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An under sized cord
will cause a drop in line voltage resulting in loss of power and overheating. The table shows the correct size to use depending on cord length and
name plate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Compressors installed on the 500L tank, with capacity of HP7.5/ 55kW and HP10/7.5kW can be supplied a star/triangle starting control unit.
Installation instructions:
Secure the control unit box on a wall or on a xed support, and provide it with a power cable with plug, of a diameter in proportion to its length.
Any damage caused by incorrect connections of the power line to the mains, automatically excludes warranty of electrical parts.
To avoid connection errors, we advise you to contact a specialised technician.
Important:
Never use the ground socket instead of the neutral wire. The ground connection must be made to meet safety standards (EN 60204).
The plug of the power cable must not be used as a switch, but must be tted in a power socket controlled by a suitable differential switch
(thermal breaker).
Starting:
Check that the mains power matches that indicated on the electrical data-plate (Fig.14) – the permissible tolerance range is +/-5%. When rst
starting compressors operating on 3-phase voltage, check the rotation direction of the cooling fan by comparing it with the direction of the arrow
on the belt guard or on the protective housing.
Turn or press into position “0” (according to the type of pressure switch tted on the appliance) the knob located on the upper section (Fig. 15).
Fit the plug in the power socket (Fig. 12 - 13) and start the compressor, turning the pressure switch knob into position “I”. The compressor is fully
automatic, and is controlled by the pressure switch which stops it when tank pressure reaches maximum value and restarts it when it falls to
minimum value. The pressure difference between maximum and minimum values is usually about 2 bar (29 psi).
The compressor will stop when it reaches exceeds the maximum operating pressure 8 bar (116 psi) and will restart automatically when the
pressure inside the tank drops to 6 bar (87 psi).
After connecting the compressor to the power line, load it to maxi-mum pressure and check exactly how the machine is operating.

ELECTRICAL CONNECTIONS
Electrcal powered compressors must be connected to a power socket protected by a suitable differential switch (thermal-breaker).
The motor of coaxial compressors is equipped with an automatic thermal breaker located inside the winding – this stops the compressor when
motor temperatures reach excessively high values.
If the breaker is tripped, the compressors restarts automatically after 10 to 15 minutes. The motors of compressor models coaxial double cylinders
are supplied with a manually resetting automatic amperometric thermal-breaker, located outside the terminal board cover.
When the breaker is tripped, wait for a few minutes and then reset the breaker manually (Fig. 20).
The motors of the belt drive series compressors are supplied with a manually resetting amperometric thermal-breaker, located on the terminal
board cover. When the breaker is tripped, wait for a few minutes and then reset the breaker manually (Fig. 20).
The safety davice is automatic in three-phase and silent compressors.
When the thermal-breaker is tripped, the pressure switch is re-leased to “0” (OFF) position.
Wait for a few minutes and return the pressure switch to “I” (ON) position. For compressors supplied with a control unit, the thermal-breaker is
installed inside the control unit. When the thermal-breaker is tripped, observe the following procedure (Fig. 22):
• Turn the switches on the control unit cover to position “0”, open the cover and press push-button 1 of the thermal-breaker. Close the cover of
the control unit and restart the compressor, observing the operations described in the paragraph “Starting compressors with control unit”.
The same instructions apply to compressors powered at 60Hz.

IMPORTANT
The safety valves supplied with this equipment are designed and constructed for use exclusively with compressed air, free from impurity. The
materials used in construction are suitable for operating the valve at the rated pressure and temperatures. The viton or NBR gasket conserves
the resistance characteristics, even in prolonged use. The valve caulking is designed to impede calibration, modication or tampering. Any
modication or recalibaration of of the safety valve will nullify warranty and potentially make the equipment unsafe.
Valve installation must be performed exclusively by Jefferson approved engineers. Checking the integrity of the valve before installation is
obligatory. Also, check that the valve pressure is no greater than the operating pressure of the tank or of the system that it is installed with.
• Check that the discharge ow rate of the valve is greater than the quantity of the air to discharge.
• The safety valve must be positioned directly on the tank in a vertical position, in a dry, accessible place protected against the weather and far
away from liquids or condensation.
• It must be positioned to allow sufcient space all around for correct air discharge, without causing damage to persons or the surrounding
area.
• The valve rod must be free in its movement when discharging.
• The connection between the valve and the part to be protected must be free from all kinds of choking and be as short as possible so as not
to reduce the discharge ow rate of the valve itself.
• The connection passage area must be greater than the valve orice area.
• During installation screw on the valve with a torque spanner using the hexagonal part of the body.
• Apply a maximum torque of 30Nm, paying attention not to cause any deformation; using pincers, pliers, hammers or tools other than a
hexagonal spanner is forbidden and will void warranty.
• Check that the inlet hole and the shutter are not blocked by glue, Teon or similar materials that could bind the shutter or other functional
components.
• If the valve is replaced the compressed air contained in the system must be discharged rst.
WARNING:
Jefferson Tools cannot take any responsibility for damage caused to persons and/or things due to failure to observe these instructions.
5. SAFETY VALVE
ON/OFF SWITCH
Prior to connecting the compressor to the power supply, ensure the pressure switch is on
the OFF position. On initial start-up open the reservoir condensate drain bung (A), adjust
the pressure regulator (B) to the maximum pressure. Unscrew the bung anti-clockwise to
open valve.
Pull the pressure switch (C) up to start the compressor.
Allow the machine to run for 10 minutes with the air escaping from the reservoir tank
before closing the drain bung (A).
Ensure the tank pressure reaches 8 bar as indicated on the gauge (D) before the pressure
switch shuts off the motor.
Note: When the drain bung is closed the tone from the motor will change. The compressor
motor will automatically restart when the tank pressure drops to approximately 2 bar less
than the maximum pressure.
WARNING: Never stop the compressor using the mains connection. Always switch off
the compressor by pressing the pressure switch button down. The compressed air will be
vented from the head and allowing an easy re-start.
NOTE: During correct operation a whistle of compressed air escaping/releasing will be
heard when the motor strops and a protracted whistle (approx. 20-30 seconds) whenever
the compressor is started with no pressure in the tank.
6. OPERATION

USER MANUAL
JEFC150L10B-230
150L AIR COMPRESSOR
www.jeffersontools.com 11
ADJUSTING THE OPERATING PRESSURE
You do not have to use the maximum operating pressure at all times. On the contrary, the pneumatic tool being used often requires less pressure.
On compressors supplied with a pressure reducer, operating pressure must be correctly adjusted.
Release the pressure reducer knob by pulling it up, adjust pressure to the required value by turning the knob clockwise to increase pressure and
anti-clockwise to reduce it. When you have obtained optimum pressure, lock the knob by pressing it downward (Fig. 23). For pressure reducers
equipped without a pressure gauge, the set pressure can be seen on the graduated scale located on the reducer body. On pressure reducers
equipped with a pressure gauge, pressure can be seen on the gauge itself.
WARNING: Some pressure regulators do not have "push to lock", therefore simply turn the knob to adjust the pressure.
OVERLOAD CUT OUT
The compressor is equipped with an overload cut out (E) which operates as a safety device to
protect the motor.
Should a fault occur and begin to overheat the motor the overload cut out will automatically
operate, cutting power.
This prevents damage occurring to the motor.
Allow 5 minutes for the machine to cool prior to attempting to reset the overload cut out (E) .
Press button. If after restarting the overload cut out is activated again, switch off the machine,
disconnect the power supply and contact your Jefferson Dealer for advice.
NOTE: For technical specifications and detailed instructions please refer to the instructions provided with the specific air tool/accessory.The outlet
line pressure from the tank is adjusted using regulator. Rotate the regulator clockwise to increase the pressure or anticlockwise to decrease.
The pressure is indicated on gauge.
ATTENTION: After each use set the pressure to zero to help prolong \the life of the regulator and avoid damage.
AIR LINE CONNECTION: The compressor comes equipped with a quick in line female connector. To insert a male connector, hold collar Ⓘ
backward. When fully insearted, release the collar. If a different style of connection is required the connector can be replaced.
NOTE: When fitting the replacement ensure the threads are sealed with PTFE tape for an air tight union.

Before attempting any maintenance jobs on the compressor, make sure of the following:
– Master power switch in position “0”.
– Pressure switch and the control unit switches all off, in position “0”.
– No pressure in the air tank.
Every 50 hours of duty: we advise you to dismantle the suction lter and clean the ltering element by blowing compressed air on it (Fig. 24).
You are recommended to replace the lter element at least once if the compressor operates in a clean environment, but more frequently if in a
dusty environment. The compressor generates condensate water which accumulates in the tank. The condensate in the tank must be drained at
least once a week, by opening the drain tap (Fig. 26) under the tank. Take care if there is compressed air inside the cylinder, and water could ow
out with considerable force. Recommended pressure: 1 – 2 bar max. Condensate of compressors that are oil lubricated must not be drained into
the sewer or dispersed in the environment as it contains oil.
OIL CHANGES
The compressor is lled with synthetic oil. We recommend a full change of oil in the pumping element within the rst 100 hours of duty. Unscrew
the oil drain plug on the housing cover, allow all the oil to ow out, and re-screw the plug (Fig. 27 - 28).
Pour oil into the upper hole of the housing cover (Fig. 29 - 30) until it reaches the level indicated on the stick (Fig. 9) or indicator (Fig. 11) Pour oil
into the upper hole of the head (Fig. 30) in belt assisted units designed for topping up in that area. Once a week: check oil level of the pumping el-
ement (Fig. 11) and see if it needs topping up. For operation at ambient temperature in the range -5°C to +40°C, use synthetic oil. The advantage
of this oil is that is does not lose its characteristics either in winter or summer. Do not drain used oil into the sewer or dispose of it in the
environment.
Hints For Efficient Operation
- For efcient operation of the machine at full continuing load and at maximum operating pressure, make sure the temperature of the work environ-
ment indoors does not exceed +25°C.
- We advise you to use the compressor at 70% maximum duty per hour at full load as this ensures efcient operation of the product long-term.
Storing The Packed And Unpacked Compressor
For the whole time that the compressor is not used before unpacking it, store it in a dry place at a temperature between +5°C and + 45°C and
sheltered away from weather. For the whole time that the compressor is not used after unpacking it, while waiting to start it up or due to produc-
tion stoppages, place sheets over it to protect it from dust, which may settle on the components. The oil is to be replaced and the operational
efciency of the compressor is to be checked if it is not used for long periods.
Pneumatic Connections
Make sure you always use pneumatic tubes for compressed air with maximum pressure characteristics that are adequate for the compressor.
Do not attempt to repair tubes if faulty.
Please Note: Jefferson Tools we reserve the right to make any modifications to this equipment without prior notice whenever necessary.

USER MANUAL
JEFC150L10B-230
150L AIR COMPRESSOR
www.jeffersontools.com 13
Note: Please refer to the diagrams on the next page
Loss of air in valve under pressure switch
This trouble depends on poor tightness of the check valve – take the following action (Fig. 31):
– Discharge all pressure from the tank
- Unscrew the hexagon-head of the valve (A)
- Carefully clean both the rubber disk (B) and its seat.
- Ret all parts accurately.
Air losses
These can be caused by poor tightness of a union – check all unions, wetting them with soapy water.
Compressor turns but does not load
Coaxial compressors: (Fig. 32)
- this may be due to failure of the valves (C1 – C2) or of a seal (B1 – B2): replace the damaged part.
Pulley drive compressors: (Fig. 33)
- this may be due to failure of the valves F1 and F2 or of a seal (D1 – D2): replace the damaged part.
Compressor no starting
If the compressor has trouble starting, check the following :
- Does mains power match that of the data-plate? (Fig. 14)
- Are power cable extensions of adequate diameter or length?
- Is the work environment too cold? (under 0°C)
- For belt drive series the thermal-breaker tripped (Fig. 20).
- Is there oil in the housing to ensure lubrication? (Fig. 11)
- Is power supplied to the electrical line? (sockets well connected, thermal- breaker, fuses in good condition).
Compressor not stopping
- If the compressor does not stop when maximum pressure is reached, the tank safety valve comes into operation. To repair the valve, contact
your nearest service centre.
IMPORTANT
- Do not on any account unscrew any connection while the tank is pressurised – always check if the tank is pressure free.
- Do not drill holes, weld or purposely deform the compressed air tank.
- Do not do any jobs on the compressor unless you have disconnected the power plug.
- Temperature in operating ambient: 0°C +35°C.
- Do not aim jets of water or inammable liquids on the compressor.
- Do not place inammable objects near the compressor.
- During down-times, turn the pressure switch to position “0” (OFF).
- Never aim the air jet at people or animals (Fig. 34)
- Do not transport the compressor while the tank is pressurised.
- Be careful with regard to some parts of the compressor such as the head and delivery tubes, as they can reach high temperatures. Do not touch
these parts to avoid burns.(Fig. 18 - 19)
- Transport the compressor, lifting or pulling it with the appropriate grips or handles (Fig. 4 - 6)
- Keep children and animals well away from the machine operating area.
