McHale HS2000 Round Bale Wrapper
56
8.3 Wrapping behind tractor
The following is the recommended method for working the HS2000 wrapper after a
tractor. It assumes the bales are well shaped for wrapping. However since it is
impossible to allow for differing conditions and terrain it may be necessary for the
operator to vary this.
The electronic control box must be set to programme ‘trailed’, see “Wrapping
sequence” on page 47.
1. Put film holder in working position (see section10.12).
2. Remove draw bar safety lock and fit to working position (see section 8.1).
3. Adjust drawbar angle to give optimum position using either control box buttons
or valve handle.
4. Ensure wrapping table is tipped in the fully forward position.
5. Dispensers must be positioned over wheels.
6. Ensure the bale lift arm is lowered and the clamp arm opened.
7. Select Auto on control box.
8. Drive tractor up beside the bale to be wrapped. It will take practice to line up
the bale correctly with the wrapper.
9. Press Auto Start (button 14) on the control box.
10. The wrapper should go through a sequence as follows:
(a) The clamp arm closes and lifts bale on to the wrapping table.
(b) The bale lift arm lowers to the ground.
(c) The dispensers start rotating and plastic film is applied to the bale.
(d) After a few revolutions the cut and hold releases the film.
(e) The dispensers slow down one revolution before the end.
(f) The cut and hold units move upwards to grip the film as the dispensers
complete the set number of rotations.
(g) The dispensers come to a halt and cut and hold units lower, gripping and
cutting the film.
(h) If continuous cycle is selected, the bale is tipped off, otherwise, the
operator pushes the table tip button to complete the cycle.
WARNING: Ensure the area is clear before operating the wrapper
Always ensure there is no person or wrapped bales in the way of the
wrapper before operating it again. Ensure that all bystanders remain
outside of the Danger Zone.
WARNING: When using valve handle to adjust drawbar
Engage the valve handle very gently as the machine will move.
WARNING: Stop machine to unload wrapped bale
The machine should not be moving when the bale is tipped off to avoid
damage to plastic film.
