Transporting on Trailer

Figure 2-2

Observe the following precautions while transporting the backhoe with tractor:

1.When traveling on roads, use the proper safety lights and warning signs. (Check your local regulations.)

2.When traveling over rough ground, do not exceed safe speed limits.

3.Do not make sudden starts or stops.

4.When climbing grades, be particularly careful not to make sudden starts.

Control Functions

Refer to Figure 2-3:

In front of you there are four control levers. Right and Left are determined from a seated position in the operator’s seat.

Refer to “Description of Major Backhoe Parts” Figure 1-5 on page 13 for the following controls.

Stabilizers

To the outside of the operator’s console are the controls for the stabilizers. The left lever controls the left stabilizer, and the right lever controls the right stabilizer. To raise the stabilizers, pull the levers towards yourself. To lower the stabilizers, push the levers forward (away from yourself).

Boom

The center lever on the left side of console controls the boom up and down. Pulling the lever towards you raises the boom; pushing the lever forward lowers the boom.

Pushing the lever further into detent float position renders the valve functions inoperable.

Moving this lever to the left swings the boom to the left; moving the lever to the right swings the boom to the right.

Dipper Stick And Bucket

The centered lever on the right side of console controls the dipper stick in and out and the bucket curl and uncurl. Pulling lever towards yourself moves the dipper stick in; pushing the lever forward moves the dipper stick out.

Moving this lever to the left curls the bucket; moving the lever to the right uncurls the bucket.

Familiarize yourself with these controls before beginning to operate the backhoe. After a little experience, you will be able to operate the unit with a smooth, steady motion.
