SAFE OPERATION 

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. BEFORE OPERATION 
1. 
Know your equipment and its limitations. Read and understand this entire manual before attempting to start and operate the excavator. 

2. 
Pay special attention to and obey the danger, warning and caution labels on the machine. 

3. 
For your safety, a ROPS/OPG (Top Guard Level I) with a seat belt is installed by KUBOTA. A ROPS: Roll-Over Protective Structure A OPG (Top Guard Level I): Operator Protective 

Guards of Top Guard Level I OPG (Top Guard Level I) in accordance with ISO10262 is equivalent in definition to FOPS (Falling Object Protective Structure). Always use the seat belt when the machine is equipped with a ROPS/OPG (Top Guard Level I) 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/ OPG (Top Guard Level I) 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/OPG (Top Guard Level I) is loosened or removed for any reason, make sure all parts are reinstalled correctly. Tighten mounting bolts to proper torque. 

4. 
ROPS meets requirements of ISO 3471. OPG (Top Guard Level I) meets requirements of OSHA 1926 1003/ISO 10262. 

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. 

(1) Pattern selector lever     (A) "Pattern A" (Two Pattern Selection System:TPSS) (B) "Pattern B" 
8. Do not operate the excavator while under the influence of alcohol, medication, controlled substances or while fatigued. 

9. Check the surroundings carefully before using the excavator or when attachments ar
