(c) The table starts rotating and plastic film is applied to the bale.
(d) After a few revolutions the plastic is released out of the cut & hold.
(e) The table slows down two revolutions before the required number of
revolutions is reached (electronic control).
(f) The table stops rotating when the required number of rotations is
reached. It is now lined up for tipping off.
(g) To tip the bale off, the table tip switch must be activated (electronic
machines).
(h) The bale damper raises up and the table tips.
(i) The cut and hold closes, holding and cutting the plastic film.
(j) The table and bale damper lower down and the bale is lowered to the
ground.

electronics. Always remove the ignition key from the tractor.
9.5 Wrapping behind the tractor (991 BJS)
The following is the recommended method for working the 991 BJS series after a
tractor. It assumes the bales are well shaped for wrapping. However since it is
impossible to allow for all differing conditions and terrain it may be necessary for the
operator to vary this.
1. Ensure the bale lift arm is lowered to the ground. To lower the lift arm press
switch “C” and move handle to the left. (See “991 BJS Controls” on page 33).
2. Drive tractor up beside the bale to be wrapped. It will take practice to line up
the bale correctly with the wrapper. Ensure the lift arm goes under the bale.
3. To load the bale press switch “C” and move handle in the opposite direction.
To lower the lift arm back to the ground move handle back in original direction.
4. To start the wrapping cycle move handle to the left. After about two revolutions
the cut & hold is released automatically.
5. Move the table manually into the tip off position.
6. Tip the bale by moving the lever forward in the direction of “3”. Actuate the cut
& hold using the switch “A”. (See “991 BJS Controls” on page 33).
9.6 Wrapping at the stack with remote control
(991 BER)
The following is the recommended method for working the 991 BER wrapper as a static
machine at the stack, using remote control. It assumes the bales are well shaped for
wrapping. However since it is impossible to allow for all differing conditions and terrain
it may be necessary for the operator to vary this.
