Backhoe

7.5 Safe Operating Techniques

The backhoe must be installed on the machine, set up and
otherwise ready to operate. Tractor / skid steer manual should
also be reviewed before starting.
7.5.1 Working on Slopes
Use extreme caution when excavating on a slope. Always lower
the stabilizers and bucket. If the ground is soft, use pads or
timbers under the stabilizers.
Do not attempt excavating on a slope while the backhoe is
positioned on an angle. The danger of a tip over is greater as the
center of gravity moves to the downside of the backhoe.
Fig. 21 – Tip Over Hazard
Backhoes are designed to work with the frame horizontal. The
stabilizers are used to level the machine. If this is not the case,
planks or blocking can be placed under the stabilizers to level
the machine. All four wheels must be touching the ground.
Fig. 22 – Swing boom up slope when possible
Refrain from swinging the boom to the downside of the hill.
Danger of tip over is much greater since the center of gravity
moves further to the downside of the backhoe as swing
increases.
For the greatest stability, always swing the boom up slope. If
swinging down slope must be done, do so with extreme caution.
Swing only as far as necessary to dump the bucket.

7.5.2 Excavating
Always lower the stabilizers and front loader bucket. If the
ground is soft, use pads or place wood blocking under the
stabilizers.
Do not undercut the stabilizers. Doing so could cause the
stabilizer to give way and the backhoe could tip over into the
excavation.
