ADJUSTING SWEEPER
0041
CAUTION
Adjust the four-bar linkage before each operation to avoid sweeper damage.
The mounting incorporates a four-bar linkage system that allows the sweeper to move up and down independently of the
loader arms. This feature is very important because it permits the sweeper to follow the contours of the ground, offering a good
sweep.
Sweeping with a properly adjusted mounting offers efficient performance, while using the mounting out of adjustment can
cause severe damage to the sweeper and can result in a poor sweep. If the loader arms are positioned too low, the sweeper must
support the loader arms, an amount of weight far greater than the sweeper is designed to carry. If the loader arms are too high,
the sweeper cannot sweep into the low areas.
1.
Drive the loader and sweeper to a flat surface.
2.
Lower the sweeper so the casters sit on the ground.
3.
Ensure loader arm travel struts are fitted to lift cylinders (WP 0021).
4.
Ensure crowd strut is fitting to crowd cylinder (WP 0021).
5.
Adjust top links to a horizontal position using adjustment bar (Figure 8).
