GENERAL INFORMATION
When operating the backhoe, smoothness of technique should be strived for at all times. Smoothness will
come with experience and practice at feathering the controls. Establish a flowing digging cycle to increase
operator efficiency and save unnecessary wear on the machine.
Observe the following points to obtain the best results and to fully utilize the digging force of the backhoe.
WARNING! Operate the backhoe only when seated at the controls. Any other method could result
in serious personal injury or death.
Never attempt to drive the tractor when seated at the backhoe controls.
Check the prospective digging area for hidden utility lines before operating the
backhoe or when in doubt of their location, contact the local utility companies. When
operating the backhoe in an area where utilities are expected to be present, throttle the
backhoe down and proceed with caution. If you feel the backhoe bucket made contact
with anything out of the ordinary, stop digging at once. If a utility line has been
damaged, contact the utility at once.
BEFORE YOU START DIGGING
Before any excavating is started, it is always a good idea to plan out the job first. Various things need to
be considered and taken into account prior to the actual digging. The operator should inspect the job site
and take notice of any potential hazards in the area. He should have a complete understanding of the tasks
he is expected to perform. Figure out what will be done with the spoil (excavated soil) will it be used to
backfill or be trucked out? What are the soil conditions like? Will you have to work around others? Etc.
Once you have become familiar with the jobs site and understand the job requirements, it is time to set up
for the actual digging. Position the backhoe in such a way as to minimize repositioning the unit and to
maximize digging efficiency. Consider the placement of spoil and position the backhoe to be able to dig
the maximum amount of soil, accurately, while leaving enough room for the spoil removed to be piled in
the desired area.
