The best insurance against accidents is to abide by the safety regulations. 
Read and understand this section carefully, before operating the excavator. 
Every user, however experienced, should carefully read and understand this section and those of the attachments and accessories before taking the excavator into operation. The owner is obliged to inform the operators of these instruction in detail. Keep this manual in the storage place. (See "Keeping the Operator's Manual" in the BEFORE START section.) 
1. BEFORE OPERATION 
1.     
Make yourself acquainted with the excavator and be aware of its limits. Read this operator’s manual carefully before starting the excavator. 

2.     
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 de. nition 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.     
Track can be set at the narrow width 39in. (990mm) and the standard width 49in. (1240mm). (for details see “OPERATION OF TRACK WIDTH CHANGE AND DOZER”) Do not operate in narrow track width 39in. (990mm), it makes risk of the excavator tipping over, operate always in standard track width 49in. (1240mm), except to pass through narrow space on a even ground. 


7.  Do not use the excavator under the  
in.uence of alcohol, medication as well  
as other substances. Fatigue is also  
dangerous.  
8.  Check the surroundings carefully before  
using the excavator or when attachments  
are being attached.  
•  Pay attention to the overhead clearance  
with electric wires.  

•     During excavator use do not allow any persons within the working range. 
9.     
Do not allow other persons to use the machine before having informed him on the exact operation and work instructions, and be assured that the operator’s manual has been read and understood. 

10. 
Do not wear baggy, torn or too large clothing when working with the excavator. Clothing can get caught in rotating parts or control elements which can cause accidents or injuries. Wear adequate safety clothing, e.g. safety helmet, safety shoes, eye protection, ear protection, working gloves, etc., as necessary and as prescribed by law or statutes.

11.     
Do not allow passengers to get on any part of the excavator seat throughout operation. 

12. 
Check     mechanical parts for correct adjustments and wear. Exchange worn or damaged parts immediately. 

13. 
Keep     your excavator clean. Heavy soiling, grease, dust and grass can in.ame and cause accidents or injuries. 

14. 
Use only KUBOTA authorized attachments. 

15. 
Before     starting the excavator, be absolutely sure that the excavator has been . lled with fuel, lubricated, greased and undergone other maintenance work. 

16. 
Do not modify the excavator, otherwise it could lead to unforeseen safety problems. 

17. 
Make sure attachments, particulary those utilizing quick attach systems, are securely mounted. 

2. STARTING OF THE EXCAVATOR 
1.     
Get into and out of the machine safely. Always face the machine. Always use handrails and available steps and keep yourself well balanced. Do not hold any of the control Ievers and switches. Do not jump on or off the machine, whether stationary or in motion. 

2.     
Start and control the excavator only from the operator’s seat. The driver should not lean out of his seat when the engine is running. 

3.     
Before starting the engine, make sure that all control levers (including auxiliary control levers) are in their neutral positions. Before starting the engine, make sure that the control levers, travel lever, pedals and other control elements are not stuck and can be moved smoothly. If stuck, for example, a lever may fail to return, possibly putting you in danger. If anything wrong is found, immediately pinpoint the cause and correct it. 

4.     
Do not start the engine by jumping the starter connections. Do not try to circumvent using the starter switch, otherwise the engine could start suddenly and the excavator could move. 

5.     
Make sure that the dozer is on the front side. (The dozer must be raised.) If the levers are activated with the dozer on the rear end, the driving direction is in the opposite direction of the drive levers. 

6. 
Do not run the engine in closed or badly ventilated rooms. Carbon monoxide is colourless, odourless and deadly. 

7. 
Keep all safety equipment and covers in place. Replace damaged or missing safety device. 

8.     
Precautions against tipping over. In order to secure safe operation, keep away from steep slopes and embankments. Do not swing the bucket downwards. Lower the dozer during digging. Keep the bucket as low as possible while driving upwards. Turn slowly on slopes (do not fast). Do not keep the excavator near the edges of trenches and banks, as the earth can give away due to the weight of the excavator. 

9.     
Watch out at all times where the excavator is being moved to. Keep an eye out for hindrances. 

10. 
Keep enough distance from trench and bank edges. 


• Safety for children Tragedy can occur if the operator is not alert to the presence of children. Children generally are attached to machines and the work they do. 
1.     
Never assume that children will remain where you last saw them. 

2.     
Keep children out of the work area and under the watchful eye of another responsible adult. 

3.     
Be alert and shut your machine down if children enter the work area. 

4.     
Never carry children on your machine. There is no safe place for them to ride. They may fall off and be run over or interfere with your control of the machine. 

5.     
Never allow children to operate the machine even under adult supervision. 

6.     
Never allow children to play on the machine or on the attachments. 

7. 
Use extra caution when backing up. Look behind and down to make sure the area clear before moving. 

8.     
When parking your machine, if at all possible, park on a . rm, .at and level surface; if not, park across a slope. Lower the bucket and dozer to the ground, remove the key place the control lock levers in the locked position from the ignition before you leave. 

3.AFTER OPERATION 
Before leaving the machine, 
•     
Bring the excavater on a . rm, . at and level surface. 

•     
Lower the attachments and the dozer blade on the ground. 

•     
Stop the engine. 

•     
Lock all control levers. 

•     
Remove the key. 

4. SAFE LOADING AND TRANSPORT OF THE EXCAVATOR 
1.     
Observe all regulations concerning the transport of excavators on public roads. 

2.     
Use adequately long and robust ramps when loading on a truck. (for details see “TRANSPORTING THE EXCAVATOR ON A TRUCK”) 

3.     
Do not change the running direction and to avoid a tipping over, do not try to swing the attachment crosswise to the loading ramps. 

4.     
After loading of the excavator on a truck, engage the swing lock pin. Lower the attachment on the loading plane and release the pressure from the hydraulic system. Block the tracks with blocks and wire down the excavator. After loading the excavator on a truck, tie down the undercarriage of the excavator with a strong steel wire on the truck. 


5.     
Do not brake abruptly with the excavator loaded. Mortal accidents could happen. 

6.     
If the excavator is used to tow another machine, the load must be smaller than the strength of the hook. 

7. 
Do not use hooks on the roof of canopy for lifting the excavator. 


Max. drawbar pull at 32.3 kNcoupling hook 
Max. vertical load at 2.7 kNcoupling hook 

5.MAINTENANCE 
Before doing maintenance work on the excavator, place the machine on a . rm, . at and level surface, Iower the attachments on the ground, stop the engine then remove the key and release the cylinder pressure by actuating the levers. When dismantling hydraulic parts, make sure that the hydraulic oil has cooled down suf.ciently to avoid burns. Start maintenance work carefully, e.g. loosen screws slowly so that oil will not squirt out. 
1.     
Before doing work on the engine, the exhaust system, the radiator and the hydraulics, let the excavator cool down suf. ciently. 

2.     
Turn off the engine at all times when .lling with fuel. Avoid spilling and over­.lling of fuel. 

3.     
Smoking is prohibited while tanking and handling the battery! Keep sparks and .re away from the fuel tank and battery. Flammable gases escape from the battery, especially during charging. 

4.     
Do not use or charge the re. llable type battery if the .uid level is below the LOWER (lower limit level) mark. Otherwise, the battery component parts may prematurely deteriorate, which may shorten the battery's service life or cause an explosion. Check the . uid level regularly and add distilled water as required so that the .uid level is between the UPPER and LOWER levels. 

5.     
Read and follow “STARTING WITH AN AUXILIARY BATTERY” in “OPERATION OF THE ENGINE”, when starting with an auxiliary battery. 


6.     
To avoid short-circuiting the battery, always remove the earth cable . rst and attach the plus cable . rst. 

7. 
Keep a .rst-aid box and a . re extinguisher at hand at all times. 

8.     
Do not open the radiator cap before the radiator has cooled down suf. ciently. First loosen the cap to the . rst stop and allow the system enough time to release the remaining pressure. Then loosen the cap completely. 

9.     
Leaking hydraulic .uid has enough pressure to penetrate the skin and cause serious injuries. Leakages from pin holes can be totally invisible. Do not use the bare hand for checking on possible leakages. Always use a piece of wood or cardboard. It is strongly recommended to use a face mask or eye protection. Should injuries occur with leaking hydraulic .uid, contact a doctor immediately. This .uid can cause gangrene or serious allergic reactions. 

10. 
To avoid leakage of battery acid which contains heavy metals, do not throw the battery away. 

11.     
Observe all laws and regulations concerning the disposal of used oil, coolants, solvents, hydraulic . uids, battery acids and batteries. 

12.
 To avoid .re, do not heat the hydraulic components (tanks, pipes, hoses, cylinders) before they are drained and washed. 

13. 
Use a face mask or eye protection to protect the eyes and respiratory system against dust and other foreign particles. 

14. 
Securely support excavator with stands or suitable blocking before working underneath. For your safety, do not work under any hydraulically supported devices. They can settle, suddenly leak down, or be accidentally lowered. 

15. 
Do not crawl under the excavator if the excavator is only supported by the boom and arm or the dozer. The excavator can tip over or lower itself due to hydraulic pressure loss. Always use safety struts or other appropriate supports. 

16. 
KUBOTA uses no parts which are lined with asbestos. Do not use these kind of parts even if they can be installed. 

17.
 Fire prevention Excavator and some attachments have components that are at high temperatures under normal operating conditions. The primary source of high temperatures is the engine and exhaust system. The electrical system, if damaged or incorrectly maintained, can be a source of arcing or sparks. The following .re prevention guidelines will help to keep your equipment up and running ef.ciently and keep the risk of .re to a minimum. 

•     
Blow off all accumulated debris near hot engine exhaust components such as turbocharger and exhaust manifold as well as exhaust pipes and muf. er more frequently when working in severe conditions. 

•     
Clean out all accumulated . ammable debris such as leaves, straw, pine needles, branches, bark, small wood chips and any other combustible materials from inside the machine belly pans or lower unit structures as well as from area in proximity to the engine. 

•     
Inspect all fuel lines and hydraulic hoses for wear or for deterioration. Replace them immediately if they begin to leak. 

•     
Examine electrical wiring and connectors frequently for damage. Repair any wires that are loose or frayed before operating the machine. Clean all electrical connections and tighten all electrical connections as necessary. 

•     
Inspect the exhaust system daily for any signs of leakage. Check for broken pipes and muf.er and also for loose or missing bolts, nuts and clamps. If any exhaust leaks or fractured parts are found, repairs must be completed prior to operation. 

•     
Always keep a multipurpose . re extinguisher on or near the machine. Be familiar with the operation of the . re extinguisher.
