SAFE OPERATION 

SAFE OPERATION 

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 "Operator's Manual Storage" in "CHECKS BEFORE START" section.) 
1. BEFORE OPERATION 
1. 
Make yourself acquainted with the excavator and be aware of its limits. Read the operating instructions 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 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). Do not modify structural members of ROPS 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 ROPS is loosened or removed for any reason, make sure all parts are reinstalled correctly. Tighten mounting bolts to proper torque. 
4. The seat     belt must be inspected regularly and replaced if damaged. 

5. 
Always sit in the operator's seat when starting engine or operating levers or controls. 

6. 
Study control lever pattern A and pattern B. Then choose the one which is most familiar. Familiarize yourself with the pattern selected by operation slowly at low engine speed. 


A     Engage the lever lock to prevent accidental pattern change. 


7. 
Do not operate the excavator while under the influence of alcohol, medication, controlled substances or while fatigued. 

8. 
Check the surroundings carefully before using the excavator or when attachments are being attached. 


A     Pay attention to the overhead clearance with electric wires. 


A     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 completely understood. 
10.Do not wear baggy, torn or oversized 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. 

(1)
 Helmet     (7) Straw hat 

(2)
 Clothing fit for work (8) Towel 

(3)
 Tight seams (9) Baggy trousers 

(4)
 Good grip footwear (10) Loose cuffs of the shirt 

(5)
 Well fitting cuffs (11) Baggy shirt 

(6)
 Working gloves (12) Rubber sandals 


11.Do not allow passengers to ride on any part of the excavator at anytime. The operator must remain in the excavator seat during operation. 
12.Check mechanical parts for correct adjustments and wear. 13.Keep your excavator clean. Heavy soiling, grease, 
dust and grass can cause fires, accidents or injuries. 14.Use only KUBOTA authorized attachments. 15.Before starting the excavator, be absolutely sure that 
the excavator has been filled with fuel, lubricated, greased and undergone all necessary maintenance. 16.Do not modify the excavator, otherwise it could lead to unforeseen safety problems. 
17.Do not hammer anything that is above the operator's seat level. Objects may fall into the operator station of mini-excavator from front. 
18.Make sure attachments, particularly those utilizing quick attach systems, are securely mounted. 
SAFE OPERATION 


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 levers 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 lock levers are in position "Lock" and all control levers and pedals are in their neutral positions and the seat belt is fastened correctly. 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. 
Make sure that the dozer blade is in front of you. (The dozer blade must be raised.) If the levers are activated with the dozer blade at the rear, the tracks will move in the opposite direction of the drive levers. 

5. 
Do not operate or idle engine in a non-ventilated area. Carbon monoxide gas is colorless, odorless, and deadly. 

6. 
Keep all safety equipment and covers in place. Replace damaged or missing safety devices. 

7. 
Precautions against tipping over. Keep away from steep slopes and embankments. Do not swing the bucket downhill. Lower the dozer blade during digging. Keep the bucket as low as possible while driving uphill. Turn slowly on slopes (at reduced speed). Do not place the excavator near the edges of trenches and banks, as the earth can give away due to the weight of the excavator. ALLOWABLE CLIMBING ANGLE : 36 % (20 deg.) ALLOWABLE ANGLE IN CASE OF CROSSING SIDEWAY : 27 % (15 deg.) 

8. 
Watch out at all times for the area to which the excavator is being moved. Pay attention to any hindrances. 

9. 
Keep enough distance from trench and bank edges. 


C     Safety for children 
Tragedy can occur if the operator is not alert to the presence of children. Children generally are attracted 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 not a 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 oper
