Operation
The High and Low-Pressure Hoses
The compressor is equipped with a high pressure hose (1) and a low-pressure hose (2). The high pressure hose is for inflating high-pressure items like tires and sports balls. The low-pressure hose is designed for inflating or deflating low-pressure, high-volume items like air rafts, mattresses, and beach balls.
Note : Pressure gauge display and preset features are used only in high pressure hose applications

The Main Switch
Set the main switch (3) to the I position to turn on the low-pressure pump or the II position to turn on the high-pressure pump. Set the main switch to the O or center position to turn off the compressor.

The operating Panel and the digital Gauge
The digital gauge in the operating panel (4) shows the current and the preselected pressure. The pressure can be displayed in psi, bar, and kPa.

1. The digital gauge turns on while the main switch is in the high pressure position II.
   Note : Make sure the digital gauge is set at 0 before use. If the gauge reads “Err” or needs resetting, remove the battery and replace it after at least 10 seconds.

2. To change the units in which the air pressure is displayed the compressor must be in the measuring mode (current value is displayed). Press the “Unit” button to switch through the available units. The units are indicated on the right side of the display.

3. Use the (+) and (-) buttons to set the target value. To change the value more rapidly hold the respective button. When the desired target value is displayed, press the “Start” button to start up the compressor.

4. To permanently set a target value repeatedly press the “Select” button until the “1” is displayed at the bottom of the display next to the target value. Press the “Memo” button. The selected target value flashes briefly and is saved. It reappears when this function is selected again with the “Select” button.

5. The compressor comes with three preset values. You can select these values with the “Select” button: A value for balls is preset (0.7 bar), a value for typical bicycle tires (3.80 bar), and values for typical automotive tires (2.30 bar). Together with the values a ball, bicycle or car symbol is displayed in the right-hand side of the display.

6. With the “Start” button you can turn on the high-pressure pump.

The Work Light
The compressor is equipped with a work light (8). The work light turns on when the compressor is turned on. It turns off a few seconds after the compressor is turned off.

Inflating Items
Note : Do not use the compressor for more than 10 minutes continuously and allow it to cool down for at least 10 minutes. Otherwise, the compressor may overheat and become permanently damaged.

Inflating with the high-Pressure Hose
The air chuck on the high pressure hose (1) can be used without an adaptor to inflate motor vehicle tires or with any application that has a valve stem that fits the air chuck opening.
Note : When inflating items of 1.0 PSI or less, inflate in short bursts and check after each burst by feel or with a calibrated measuring device to determine accurate pressure.

• Set the desired target pressure.

• Clamp the end of the air chuck down onto the valve stem by pressing air chuck clamp down until it stops or is parallel with the high-pressure air hose.
  Note : The pressure readout on the gauge while inflating is a meashttps urement of the fluctuating pressure between the item and the high pressure hose. To get an accurate reading, stop inflating and follow above instructions for reading the air pressure.

• Set the main switch (3) to II to start inflating.

• The compressor will run until the target pressure is slightly exceeded, then it will decrease the pressure to reach the target pressure.

• When the desired pressure is reached and the compressor has stopped set the main switch to O.

• Remove the hose and store in hose wrap on the right side of the compressor.

• Turn off the display by pressing and holding the (+) and (-) buttons until the display turns off.
  Note : Stand at least half a metre away from item being inflated.

Use of the Adaptors
The high pressure air hose can be used with the provided adaptors to inflate a variety of items.

• Insert the adaptor (or needle) into the air chuck and push the air chuck clamp down until it locks into place. Inflate to the desired pressure.
• Remove the adaptor by lifting the air chuck clamp up and pulling the adaptor (or needle) from the air chuck.

Inflating with the low-Pressure Hose
The low-pressure hose ls used to inflate low-pressure items, such as air mattresses, pools, and floats.
Note : A pinch valve adaptor (7) comes as part of the inflating nozzle assembly that is attached to the end of the low-pressure hose. The pinch valve adaptor is used for items that have a smaller air opening or pinch valve. Insert the pinch valve adaptor into the pinch valve, ensuring that the tip of the adaptor is inserted past the inner “flap” inside the valve.
When inflating, ensure that the tip is not blocked during inflation.

• To attach the low-pressure hose, align the slots in the hose with the pins on the sides of the inflation flange (5).
• Turn the hose clockwise as far as it will turn.
• Use the suitable adaptor to connect the hose to the item to be inflated.
• Set the main switch (3) to low pressure (I) to start inflating.
• When the desired pressure is reached set the main switch to O and close the valve of the item inflated.
• Remove the hose by turning it counterclockwise as far as it will turn and removing it from the inflation flange.
• Store the hose in hose wrap on the left side of the compressor.
  Note : Always leave the low-pressure hose free of obstructions and with the pinch valve adaptor off when not in use. Overheating could occur if the low-pressure hose ls blocked.

Deflating with the low-pressure Hose
The low-pressure hose, when placed ln the deflation flange (6), can be used to remove air from inflated items.

• Place the hose inside the deflation flange (6).
• Set the main switch to low pressure (I) to start deflating.
• When the item has been deflated, turn the main switch to O.
• Remove the hose by pulling if from the deflation flange.
• Store the hose in hose wrap on the left side of the compressor.

Inflating manually for high and low Pressure Applications

• Connect either high or low pressure hose to the compressor and to the item to be inflated.

• Set the main switch to I or II (low or high pressure) until desired pressure is reached.
  Note : Stand half a metre away from item being inflated.

• Set the main switch to O.

Accessories
The supplied accessories perform a variety of functions.
The tapered adaptor can be used on smaller pinch valves to inflate items like floats and children’s toys, which usually require the user to inflate them by blowing air into item. The sport ball needle can be used to inflate any type of sports ball or any other item that requires an inflation sport ball needle.
Note : When inflating items of 1 o PSI or lass, inflate ln short bursts and check after each burst by feel or with a calibrated measuring device to determine accurate pressure.

How to use the Sport Ball Needle

• Insert the needle into the air chuck on the hig pressure hose (1) and push the air chuck clamp down until it locks into place. Inflate to the desired pressure.
• Insert the moistened sport ball needle into sports ball valve and inflate.
• Remove sport ball needle from the ball and from the air chuck after Inflation.
  Note : The pressure required for most sports balls ls too low for accurate reading on gauge.

How to use the Presta Valve Adaptor
The Presta valve adaptor can be used for Presta valve stems as described below. Before inflating a tyre with a Presta valve, loosen the locking nut on top of the valve. Once Inflation is complete, tighten the locking nut 1o seal the tyre valve.

• Loosen the Presta valve locking nut.
