Troubleshooting

Er1, Er2, Er4 or Er8 on screen –disconnect tire and reset power, if it continues
contact service.
Blank Display - check voltage supply.
If a constant air leak is noticed in the tire hose –hoses are probably installed
in reverse position.
Er3 on screen - verify the incoming pressure, it is probably lower than
necessary. It is also possible to have a clogged incoming filter at your unit, in
this case unscrew the hose connector at the unit’
s valve and clean the filter.
Er7/Chuc on screen - verify if chuck is clogged and change it for an “open-
end” one. It also appears if chuck stays connected to the tire more than 15
seconds.
If Tire Gauge does not reach the desired pressure, and gives a higher or a
lower value instead –look for air leaks on hose, connections and chuck.
If calibration takes a long time - clean airline or filter.
If Tire Gauge does not perform calibration - push “FLAT TIRE” button if tire is
empty, or replace chuck.
If beep sounds when there is no tire connected to the hose - verify whether
chuck is clogged or a “closed end” style and unclog or replace it with an
“open-end” style.
If it seems that Tire Gauge is functioning by itself without stopping- verify
whether chuck is clogged or a “closed end” style and unclog or replace it
with an “open-end” style.
