Proper Use
The device is intended for the automatic filling of tyres and for checking the
pressure of such vehicle tyres.
Two design variants with 5.5 and 10.0bar max. fill pressure for passenger-
car and/or lorry tyres.
National permit by PTB available. Registration number: 18.08/08.06.This is
the prerequisite for calibration. The calibration can be performed either by the
manufacturer or by the customer and is valid for two years. For the setup
and operation at public filling stations and service stations in the Federal Re-
public of Germany, only calibrated devices may be used!
Warning symbol
This symbol should alert the user of important operating tips and
steps involved in preventative maintenance – the compliance with
which is crucial to safe operation.
Caution!
Tyre-filling-machine with 10 bar max. Inflation pressure may only be used for
the filling of truck tires! These devices are marked with the words' for trucks.
The use for car tires only one device at 5.5 bar max. Inflation pressure used!
Excessive tire pressure can lead to the bursting of the tire.
The filling of bicycle tyres and other small tyres is prohibited due to
the risk of over-filling!
Electrical Connection
• The mains voltage may lie within the range of 90 to 240V/50-60Hz
• The electrical connection must be grounded.
• The electrical connection must be safeguarded with a 10 A fuse (depen-
ding on heat output) which is easily accessible - and marked as a current
interruption for your device.
• Never connect any other electrical consumers such as the cooling unit, the
compressor or the vacuum cleaner to the same power source.
Let basically make electrical connections by qualified personnel.
Hose Fixture
The device can be equipped with a straight as well as a spiral hose.
The straight hose can either be coiled around the device between the front
panel and the wall, or on a hose fixture. The spiral hose should be hung onto
the designated fixture. As an option, an automatic hose reel is available. This
accident can be prevented from tipping and to prevent damage to the hose
and the plug.
Installation and Setup
• The device is suitable for assembly inside or outside.
• The device must be attached with four screws to the wall or to a column.
• Connect the hoses for the pressure supply and for filling according to the
affixed markings (G
1/4female thread).
• Guide electrical and pressurised-air lines along the wall to prevent acci-
dents.
Setup of the device in explosion-prone areas is prohibited!
Package Contents
The airmate standard model is supplied including the following:
• 3m electrical cable with contact-safeguard plug
• Operation guide
Air-supply and fill hose both sold separately.

Caution!
• Ensure that the pressure on the air-supply hose is no higher than 6.0bar!
If necessary, install a pressure regulator!
• Notwithstanding the plastic filter element assembled in the hose connec-
tor, it is advisable to add a pressurised-air filter.
• To ensure safety, install a ball valve in front of the tyre-filling device. Prior
to its connection, open this valve fir a short time to enable the rinsing of
any dirt particles from the line.
• It is advisable to install a residual-current-operated device (RCD) with 30
mA.

Operation
The manufacturer's pre-set fill pressure amounts to 1.8bar.
1. Set the desired tyre pressure with the plus/minus buttons.
2. Attach the fill hose with a clip connector to the tyre valve and secure it with
a half-turn. The fill process then begins automatically. In Breaks filling it
shows the current pressure.
3. The fill process has ended when the alarm tone sounds and the display
screen is blinking. The connector can now be removed.
4. For empty tyres (tyre pressure <0.2bar), the fill process does not begin
until the "flat tyre" button is pressed. After attaining the value of 0.3bar,
the fill process is automatically continued.
5. With the "bar/psi" button, the pressure check can be performed in anot-
her unit of measure. After this button is released, the reading appears
once again in bar.
• If the same pressure is required for the next tyre, it is sufficient to attach
the connector, and the fill process starts again.
• If the pressure in the tyre exceeds the desired level, the excess amount
of air is discharged.
• When the valve connector is re-attached following the fill process, a slight
drop is pressure occurs. The missing amount of air is then immediately re-
filled.
• After approx. 1 minute rest time, the fill-pressure indicator is reset to 1.8
bar for safety.
Safety Measures During Use
• Check to verify the moment connector is properly attached to the vehi-
cle's valve. After attaching, secure it with a half-turn. Any leakage will lead
to inaccuracies in the fill process.
• The fill process should not be interrupted. If the valve connectors detach
from the valve, first wait fort he air to dissipate, then re-attach the con-
nector.
• The filling process can be interrupted at any time with the "flat tyre" - but-
ton!
• Do not leave the hose on the floor, and do not drop the connector. After
each use, always retract the hose /hang it up
• If the fill process does not start after attaching the valve, check the valve
rod on the tyre and replace it if necessary.
• When the hose or connector leak, they should be replaced promptly.
Preventive Maintenance
Prior to performing any preventive-maintenance work on the electrical com-
ponents, the power supply must be disconnected and the air-shutoff valve
closed.
1. Replacement of hose
Detach the hose-connector fitting with an open-ended wrench. The com-
pressor symbol represents the air intake; the tyre symbol tyre filling. The
hoses must be designed for pressure levels up to 16 bar. When replacing
the hose, always ensure that the plastic sinter filters do not fall out.
Then, seal off the hose connectors (i.e., with Teflon strip) and screw them on
tightly.
2. Replacement of connector
Only use the moment connector supplied by the manufacturer. Other con-
nectors can lead to leakage. Only open design to use. The plug should be
rotated on the hose to be mounted.
3. Replacement of the fuse
Since the fuse is situated on the inside of the device, the tyre-filling machine
must be re-calibrated after it has been opened. The casing may only be ope-
ned by the respective technically trained personnel. Only use those fuses
which have been duly recommended by an accordingly certified testing in-
stitution: 2 mA with delay, and only Type 5 x 20 mm.
Guarantee
The airmate tyre-filling device has a 12-month guarantee period (starting
from the invoice date).
The guarantee applies to potential material defects or manufacturing errors
which occur in the course of proper use and have also been technically ve-
rified and determined by the supplier.
The following are excluded from the guarantee:
• Damage resulting from improper handling of the device or accidents of
any kind, such as i.e., power surges due to lightning strike.
• damages which have occurred due to abnormal electrical fluctuation in the
electrical mains.
• defects caused by the improper assembly of the device.
• expendable parts such as hoses and plugs.
• electrical fuses.
Expiry of the Guarantee Period
The guarantee period will end if and when:
• the term of validity elapses,
• any modifications and the installation of improper components are per-
formed,
• technical servicing has been performed by non-qualified personnel,
• the operation guide has not been observed,
• the seal (lead seal) has been removed or damaged.
Repair
• The device must be sent along with a description of the error/malfunction
to the manufacturer or its representative. Initially, the customer bears the
associated shipping costs.
• For on-site repairs performed by the manufacturer or its representative,
the principal must bear (in addition to the incurred material and labour
costs) the fitter's transportation costs.
• The parts replaced free of charge to the customer due to the warranty
conditions are the property of the manufacturer.
• Due to constant further technical developments, the product's technical
specifications are subject to change.
