To facilitate opening of the cowling and to keep it open for routine service, it has been fitted
with two Support Gas Struts. For major maintenance work it may be necessary to open the
cowling all the way as in the photo to the right.
To open the cowling all the way follow these steps:
Do not perform this work on a windy day; a strong
wind may damage the unit while the cowling is up-
right.
Have a helper standing by; two people are required
to disconnect the gas struts safely.
Secure the machine on level ground with the jack
stands and retract the manifold approximately 3 to 4
feet. It will be the support base for the cowling in
the vertical position. Place some protective materi-
al, such as cardboard onto it to prevent paint from
being scratched.
To disconnect the gas struts, pull the lower sockets
by hand sharply off the ball joints affixed to the fan
mount while your helper is holding the cowling in
position
After both struts have been disconnected from the
fan mount, gently push the cowling backwards until
it rests on the manifold. It will stay in the open posi-
tion by design.
Before closing the cowling again, re-attach the two
gas struts by snapping their sockets firmly onto the
fan mount bracket balls by hand while a helper is
holding the cowling in position. Make sure that the
gas struts are safely attached.
Should it become necessary to detach the cowling from the base by unbolting the
hinges, make sure that the shims under the hinges, if any, are replaced as originally
installed.
DANGER:
Make sure that the T-400 is placed on level ground with the jack
stands secured. Do NOT perform this work outdoors on a windy day. Have a
helper standing by to assist you, as the cowling is heavy.
