10. Adjust the chain as described in Section 11.2
11. Replace the chain guard and tighten the 2 x handwheels
12. Adjust the electronic control box to the correct number of wraps
11.4 Table rollers/belts
The wrapper normally leaves the factory with rollers set to the correct width for a 1,250
diameter bale. Sometimes it may be necessary to narrow the rollers for a smaller
diameter bale or widen them for a larger diameter bale. The belts should support the
full weight of the bale and should sit tightly between the rollers.
1. Loosen the 4 x M14 nyloc nuts and bolts holding bearings on idle roller.
2. Move roller as desired ensuring both ends are moved the same amount.
3. Tighten the 4 x M14 nyloc nuts and bolts.

11.5 Table stop position magnet (991 BE &
991 BER)
If the table does not stop in the correct position in line with the chassis it is possible to
move the magnet that controls the stop position. However, it must be checked first that
the machine is operating at the correct speed, has a bale on the table and the plastic
film is attached, as all of these factors will have a bearing on where the machine stops
(See Section 15.1.1 in “Trouble Shooting” on page 81).
The magnet may be adjusted as follows:
1. Tip up the table and fit the safety bar
2. Identify the magnet to be changed. There are two sets of magnets near the
outside of the table. The magnets that require adjusting are positioned furthest
away from the cut & hold.
3. Loosen the M6 bolt and nyloc nut holding the magnets in position
4. If the table does not turn far enough, push the magnets in the direction shown
5. If the table turns too far, push the magnets in the direction shown
6. Tighten the M6 bolt and nyloc nut (Do not overtighten as the magnets may
crack or shatter)
