Timberline Binar-5B-Compact - Replacement of the Plug Screen

10
A glow plug screen is installed to
equalize the fuel supply to the
combustion chamber.
When changing or checking the plug,
check the screen for fouling or clog-
ging as well. If the screen is fouled,
replace it. Install the screen into the
diesel chamber nozzle using the man-
drel, as shown on Fig. 3 and 4.
For a gasoline chamber, the screen is
installed onto the plug (Fig. 2a) and
then screwed all the way in. To prevent
clogging, clean a Ø2.8 mm opening
located on the lateral cylindrical
surface of the nozzle before installing
the screen into the nozzle
The screen must be installed fully
tensioned. Where it is installed without
having complete contact with the end
face, the pre-heater may fail to launch.
When installing the screen for a Bi-
nar- 5B-Compact (gasoline-operated),
visually inspect the screen (Fig. 3а)
for burrs (Fig. 3b). Carefully cut off any
found burrs with scissors. Install the
screen onto the plug as shown on
Fig. 2a and screw it into the
combustion chamber.
