Figure 3. Backhoe Swing Area.
POSITION THE MACHINE
Before operating in an unfamiliar area, walk around the full length of the proposed site and check for hidden holes,
Lower stabilizers until they carry the weight of the back- hoe. If tractor is equipped with a front loader, place the bucket flat on the ground. Lower loader lift arms until weight is removed from front tractor tires.
Level the machine using stabilizers and front loader before starting to dig.
Stability is very important when operating backhoe in the extreme swing positions as this causes weight transfer.
CONTROL HANDLE OPERATION
Refer to Figure 4.
Assume your position in the operator's seat.
When engaging optional
When becoming familiar with backhoe controls, start with a lower rpm.
Before operating, perform a functional test by placing control handles in their various positions and making certain correct operation occurs, matching decals on operator's console. Pay specific attention to the float position of boom. Do not operate backhoe if functions differ from decal; serious injury or death could occur.
It is not difficult to become a successful operator. Con- trol lever operating decals (shown in Figure 4) are next to the operating control levers. Study these decals; they will assist you in becoming familiar with the con- trols.
Pushing handle 1 forward will lower left stabilizer; pull- ing back raises it.
Pushing handle 2 forward will lower right stabilizer; pulling back raises it.
Pulling left control back (toward A) raises boom; push- ing it forward (toward C) lowers it. Full forward (toward C) is the float position.
Moving left handle left (toward B) swings boom left; moving it right (toward D) swings boom right.
Pulling right control back (toward E) moves dipper down and toward operator; pushing it forward (toward G) moves it up and away from operator.
Moving right handle left (toward F) curls bucket toward operator; moving it right (toward H) extends bucket out away from operator.
Operate the control levers, swinging the boom several times to practice control. Do not operate the swing more than 45° each way the first few times. Gradually increase arc.
