Open the front panel by pulling straight out until it stops. Then you will be able to swing
panel open to the right.
If the head is a 450ul backfill first insure there is no water in the head, bottle or hoses. Then
loosen the clamp holding the hose on to the fitting on the back left over the backplane and
remove the hose.
Loosen the four hold down bolts and pull the head forward enough so that you can reach
the two connectors on the top left of the backplane. Once these are disconnected, lift the
head up and forward, being careful not to damage the tips if they are still attached. You
may want to remove the connectors first. To do this, loosen the two forward captive screws
that secure the B Q96 control board mounting plate all the way out. Loosen the two back
ones enough to pivot the plate and then tilt the plate up in front enough to access the two
connectors. Place the head in the storage stand. Never stand the head on the tips or
place it where the tips may be damaged.
