CLEANING THE QEV
Note: Certain models of the Ego7 may contain more than
one QEV.
The QEV used on the Ego7 is new and improved compared
to previous versions. One of the improvements that we
wanted to prioritise was the fact that you can now strip and
clean your QEV without the use of any specialist tools. With
the frame already separated from the marker body and the
minifold disconnected from the QEV, use the correctly sized
at head screw driver to unscrew the banjo tting section of
the QEV from the marker body (SEE FIGURE 16.1).
With the QEV completely removed from the marker, gently
unscrew the silver barb cap from the QEV body (SEE FIGURE 16.2).
This will allow the cone shaped internal seal to be removed
from the barb cap and cleaned if necessary. At this stage
your QEV should be split into three separate components;
QEV body (blue), QEV seal (black) and barb cap (silver)
(SEE FIGURE 16.3). Check that the 4 inlet holes and the exhaust
ports on the QEV body are free from dirt and debris as this
will effect the performance of your QEV. If they are at all
blocked, remove any debris to unblock them.If your internal
QEV seal is damaged then replace that at this time
To rebuild your QEV insert the cone shaped internal seal into
the barb cap with the tip of the cone pointing towards the
barb. Having checked that the seal is sitting snugly inside
the barb cap, screw the barb cap onto the QEV body. Using
the correct sized at head screw driver, screw the banjo
tting section of the QEV to the marker body making sure
that the QEV lines up parallel to the marker body when it is
tight.
Reconnect the low pressure hose from the minifold to
your QEV and re-assemble the marker. You have now
successfully stripped and cleaned your QEV.
WARNING: DO NOT OVER-TIGHTEN THE BANJO FITTING!
