is
made
to
extend
out
the

must
be
removed
in
order
to
close
the

This
is
to
prevent
leaving
the

blocked
accidentally
after
maintenance
.
Each
mechanism
is
furnished
with
a
blocking
device
and
should
remain
in
the
bottom
of
the
house
since
the
spring
centers
may
differ
from
unit

.
Manual
operation
of
the
mechanism
should
not
be
attempted
until
the
bearing
