4. Turn the support arm through 90 degrees (pointing upwards) and push the
support arm back into place. Secure it with the large linch pin.
5. Lower the bale damper cradle plate down again.
6. The machine is now ready to side tip bales. When side tipping bales, the
machine must be stopped during tipping.
7. Reverse this procedure to change back to normal tipping. The side tip rear
extension piece must be removed for normal tipping, if fitted.

9.4 Wrapping behind the tractor (991B series)
The following is the recommended method for working the 991B 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.
The electronic control box (if fitted) should be set to program “O” for a 991B series
machine. The table must be in the correct starting position. Refer to “Electronic Control
Box Functions” on page 45 on setting the control box for more details.
Follow the procedure below:
1. Ensure the bale lift arm is lowered to the ground.
2. Drive the 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. Actuate the hydraulic control valve (manual control) or switch to load the bale
(electronic control).
4. The wrapper should now go through a sequence either worked manually, or
automatically on electronic machines.
(a) The bale lift arm lifts the bale onto the wrapping table (manual). On
electronic machines the auto load cycle can be activated using the control
box.
(b) The bale lift arm is lowered to the ground again manually (manual
machines). It is lowered automatically in electronic machines.
WARNING: Keep out of the “Danger Zone”
Keep all persons outside of the “Danger Zone” during all machine
operations! See “Danger Zone” on page 14.
