SAFE OPERATION
Careful operation is your best insurance against an
accident.
Read and understand this manual carefully, before
operating the excavator.
Every user, however experienced, should carefully read
and understand this manual and those of the attachments
and accessories before operating the excavator. The
owner is obliged to inform all operators of these
instructions in detail.
Keep this manual in the storage location. (See "Where to
keep Operator's Manual" in "MAINTENANCE" section.)
1. Know your equipment and its limitations. Read and
understand this entire manual before attempting to
start and operate the excavator.
2. Obey the danger, warning and caution labels on the
machine.
3. For your safety, a ROPS/FOPS (Roll-Over Protective
Structure, Falling Objects Protective Structure.) with a
seat belt is installed by KUBOTA. Always use the seat
belt when the machine is equipped with a ROPS/
FOPS as this combination will reduce the risk of
serious injury or death, should the excavator be upset
or falling objects occur.
Do not modify any structural members of the ROPS/
FOPS by welding, drilling, bending, grinding or cutting,
as this may weaken the structure. If any component is
damaged, replace it. Do not attempt repairs. If the
ROPS/FOPS is loosened or removed for any reason,
make sure all parts are reinstalled correctly. Tighten
mounting bolts to proper torque.
4. ROPS/FOPS structure complies with ISO 3471, ISO
3449 and OSHA regulations.
5. The seat belt must be inspected regularly and
replaced if frayed or damaged.
6. Always sit in the operator's seat when starting engine
or operating levers or controls.
7. Study control lever pattern A and pattern B. Then
choose the one which is most familiar.
Familiarize yourself with the pattern selected by
operating the unit slowly and at low engine speed.
A Engage the lever lock to prevent accidental pattern
change.
8. Do not operate the excavator while under the influence
of alcohol, medication, controlled substances or while
fatigued.
