Move lever to left, the bucket curls in. Move lever to right, the bucket extends out.

By moving the lever to one of the intermediate posi- tions, the dipperstick can be extended or retracted at the same time the bucket is being loaded or dumped.

The two operations of the boom lever, combined with the two operations performed by the bucket and dip- perstick control lever, provide four simultaneous oper-

ations from the two levers, keeping cycle time to a minimum.

In general, the direction of movement of a control lever corresponds to the movement of the operating member.

Operating the Backhoe

CAUTION

To avoid possible injury, observe the following safety rules WHEN OPERATING the backhoe.

1.DISENGAGE safety locks as shown in Figure 3 before attempting to operate the backhoe. Store lockpins in holes provided in operator platform.

2.OPERATE from the backhoe operator’s seat only.

3.LOWER the stabilizers until the rear of the trac- tor is totally supported by them. NOTE: rear tires should not come up off of the ground. See dia- gram on Page 11.

4.DO NOT dig near the stabilizers.

5.DO NOT touch overhead wires with any part of the backhoe.

6.DO NOT attempt to raise the tractor off the ground or move the tractor forward or backward using the backhoe dipperstick or bucket.

7.DO NOT lose stability by swinging the bucket downhill when positioned on a slope.

8.DO NOT lower the backhoe boom using the “float” function. It will freefall, and could result in injury to bystanders or damage to the backhoe.
