Position Indicator

The general-purpose bucket shown in figure 9-6 is normally used as a skid shovel. The multipurpose bucket shown in figure 9-7 serves as a skid shovel, but can also be used as a bulldozer, scraper, and clamshell.

Most front-end loaders are equipped with six bucket control lever positions, such as raise, hold, lower, float dump, and rollback. Dump and rollback can be used

at the same time with any other four positions. Also, most loaders have a position indicator and depth gauge indicator mounted on the bucket.

To set the multipurpose attachment as a bucket, the operator pulls the control lever back (fig. 9-11) until the

clamshell indicator is at the "O" setting on the clam product graphic (fig. 9-12).

To set the multipurpose bucket as a scraper, you open the clamshell until the indicator points to 2 or 4 on the clam product graphic (fig. 9-13). The more the clamshell is open, the deeper a cut can be made.

To use the multipurpose bucket as a dozer, you open the clamshell until the clamshell indicator is at the bottom of the clam product graphic (fig. 9-14).

When using the multipurpose blade as a dozer, you can adjust the amount of cut by the pitch of the dozer

blade. This is done by tilting the blade forward or backward, as shown in figure 9-15.

To use the multipurpose bucket as a clamshell, you open the clamshell until the clamshell indicator is at the bottom (fig. 9-16). Then you tilt the bucket forward all the way.

NOTE: Multipurpose bucket position indicators differ, depending on the manufacturer. Read the operator's manual for the type loader you are assigned to operate.
