5.2. During use
5.2.1. Flow from starting up to compressed air available state
1. This product is manufactured as an air compressor for
air tools such as nailing machines. Use for light work
only.
2. Do not operate continuously for more than 30 minutes.
The compressor body and electric motor will become
hot and this will cause reduction in the lifespan of the
product and performance degradation.
3. Do not operate at ambient temperatures above 40°C or
below 5°C (0 – 40 °C short term).
4. When connected to the power source and power is
being supplied, conrm that the operation display LED is
ashing.
5. After fully opening the drain valve, press the start/stop
switch and start up the equipment. The operation display
LED lights up.
6. Conrm that air is coming out of the drain valve dis-
charge tube.
7. Fully close the drain valve, and as the pressure in the
air tank rises, the air tank pressure display LEDs light
up from the left in order as the displayed pressure is
reached.
8. When the air tank pressure reaches approximately 42
bar, all 5 LEDs light up and the compressor halts.
9. Use the pressure reducing valve to adjust the pressure
according to the connected air tool. Turn the knob fully to
the right to increase the pressure, and next turn it fully to
the left to lower the pressure, then adjust to the required
pressure.
10. The maximum ejection pressure possible by setting the
pressure reducing valve is approximately 11 bar for
regular pressure usage and approx. 25 bar for high
pressure usage.
11. If the knob is turned fully to the left for high pressure
pressure reducing valve, the ejection pressure is approx.
5 bar (Pressure below approx. 5 bar cannot be ejected.)
5.2.2. Using compressed air and points during operation
1. Connect the air hose to the coupler and begin the work.
a. Regular pressure air outlet will not t a high pres-
sure coupler and vice versa.
Do not directly connect heavy objects such as an
air lter, pressure reducing valve or socket pair.
Turn the knob to the right:
the pressure increases
Turn the knob to the left:
the pressure decreases

UK
17
b. When lowering the pressure reducing the outlet pressure, the air inside the
connected air hose will escape into the atmosphere from the pressure reducing
valve. When this happens, a hissing sound will occur. Do not mistake this for an air
leakage.
2. Inverter Control
a. The product’s rotation speed is altered using the inverter control. As the rotation
speed alters the sound will also change. Do not mistake this as an error.
b. Inveter control may affect/be affected by radio waves, so keep the product minimum
1 m away from other electronic equipment.
3. Function to halt operation
a. This product is equipped with a function to halt operation in response to the
following faults
i. If supply voltage is abnormally high/low.
ii. To protect against overheating of the electric motor or the control box.
5.2.3. Switching the operation mode
This product’s operation can be switched depending on
user requirements. If the operation changeover switch is
pressed, the operation mode switches and the LED lights
up to show the current operation mode.
Normal operation mode
This operation mode is suitable for normal operation.
Cut-out pressure is set to approx. 42 bar.
Cut-in pressure is set to approx. 32 bar.
Power operation mode
This operation mode is suitable if a large amount of air is
needed in a short period, (e.g. a large number of nails must
be driven in at high pace).
Cut-out pressure is set to approx. 42 bar.
Cut-in pressure is set to approx. 38 bar.
Silent operation mode
This operation mode is suitable for work, where noise levels
are more important than high compressed air delivery.
The pressure settings for cut-in and cut-out are the same as
for the normal operation mode, but the electric motor
rotation speed is reduced to a maximum of 1,500 RPM which
reduces the noise level.
Note: Silent mode requires more time to ll the tank.
The operation mode is
switched if pressed.
The “Normal” LED is lit.
The “Power” LED is lit.

1. When nishing operation, be sure to halt the equipment by pushing the start/stop button.
Conrm the operation display LED is ashing and remove the plug from the power source.
2. Open the drain valve to release all the water and
compressed air from the air tank.
Do not put body parts near the drain opening. The
discharge air contains water, abrasion powder and
rust.
Gently open the drain valve. If the drain valve is
opened to quickly, the water and compressed air may
rebound off the ground or oor and hit body parts.
Note! Drain water and air can stain and discolor the
surrounding area.
3. Detach the air hose. If the air hose is detached while
compressed air remains in the air tank, the coupler
will spring out, which may cause an injury or accident.
Caution! Keep your face away, when detaching the
air hose. Failure to comply may cause blindness or
injury.
5.3.1. Storage
1. If the compressor is to be stored for a longer period (1 month or more), before storing,
fully open the drain valve, operate it for 5 minutes or more to prevent rusting.
2. Store in a dry place out of reach of children.
3. Store at a temperatures (5°C or higher) at which there is no risk of freezing.
4. Store on horizontal surface and do not store in upright position.
6. Trouble shooting
6.1. Start-up Current and Abnormal Voltage (low voltage)
Start-up current
In order to prevent halting as much as possible due to the original power supply breaker trip-
ping or the air compressor overheating, this unit is equipped with a control to keep the rated
current value to the 6.3A level.
Low voltage
If the supply voltage becomes insufcient during compressor operation, all mode settings are
overruled. Cut-in is set to 25 bar and cut-out at 32 bar.
If the unit is in a low voltage state or halted operation state due to insufcient supply voltage,
the 5 air tank pressure display LEDs ash to notify of the “low voltage”.
Gently open the drain
valve and adjust the
discharge condition.
