CLEANING THE QEV
BLOCK
With the frame separated from the marker body us a 5/32” hex
key to undo and remove the two screws that hold the QEV Block
onto the Ego8 body (SEE FIGURE 17.1).
With the QEV Block completely removed from the Ego8 body,
the bottom of the Ego8 body should now resemble FIGURE
17.2. Ensure that the two o-rings are located in their respective
pockets in the base of the body and check that they are free
from contamination from any dirt, debris, paint or moisture. If
either (or both) o-rings are damaged or missing replace them as
necessary.
Check the underside of the QEV Block to ensure that it is also
free from damage or debris (SEE FIGURE 17.3). To begin to strip
the QEV Block, turn it over to expose the QEV Block Retainer Clip
access holes and use a pick to gently poke both sides of the Rear
QEV Block Retainer Clip free from the QEV Block (SEE FIGURE
17.4). When the clip protrudes sufficiently from the QEV Block,
hook the pick into the hole in the clip to pull it free from the QEV
Block (SEE FIGURE 17.5). You should now be able to remove the
Rear QEV Cap and the QEV Diaphragm from the rear of the QEV
Block by tapping it onto the palm of your hand. (SEE FIGURE
17.6)
