7. Slowly lift the control bar to a point where the bag
just begins to inflate (about
5' below the handle).
This indicates that the mower blade is engaged
and has begun to rotate.
NOTE: This intermediate position is not the
'natural' operating position of the control bar.
However,
it has proven to be useful in early
detection of latent
BBC sticking which could
create an unsafe condition later in the life of the
mower.
8. Release the control bar.
NOTE: If a 'bang' is heard and the bag
immediately deflates, the control bar had been
raised too far. Repeat steps
5, 6, and 7, but do
not raise the handle as high as the last time.
If the control bar 'hangs up" and the blade does
not stop quickly, you should stop the blade
before shutting
the engine off, This can be done
by raising the control bar to the normal operating
position and releasing
it.

2. Loosen bottom jam nut on the wheel traction
cable
