• Remove the pilot screw 1.
(Except for E-18.)
NOTE:
Before removing the pilot screw, determine the setting by slowly
turning it clockwise and count the number of turns required to
lightly seat the screw. This counted number is important when
reassembling pilot screw to original position.
PILOT SCREW REMOVAL (Only for E-18)
Because harsh cleaning solvents can damage the O-ring seals
in the pilot system, the pilot system components should be re-
moved before cleaning.
• Use a 1/8" size drill bit with a drill-stop to remove the pilot
screw plug. Set the drill-stop 6 mm from the end of the bit to
prevent drilling into the pilot screw. Carefully drill through the
plug.
• Thread a self-tapping sheet metal screw into the plug. Pull on
the screw head with pliers to remove the plug. Carefully clean
any metal shavings from the area.
• Slowly turn the pilot screw clockwise and count the number of
turns until the screw is lightly seated. Make a note of how many
turns were made so the screw can be reset correctly after
cleaning.
• Remove the pilot screw along with the spring, washer, and O-
ring.
• After cleaning, reinstall the pilot screw to the original setting
by turning the screw in until it lightly seats, and then backing it
out the same number of turns counted during disassembly.
• Install a new plug by tapping it into place with a punch.
