SAFETY

SAFETY NOTICE

IMPORTANT SAFETY NOTICE

Proper service and repair is extremely important for safe machine operation. The service and repair techniques recommended by Komatsu and described in this manual are both effective and safe. Some of these techniques require the use of tools specially designed by Komatsu for the specific purpose.

To prevent injury to workers, the symbol ¤is used to mark safety precautions in this manual. The cautions accompanying these symbols should always be followed carefully. If any dangerous situation arises or may possibly arise, first consider safety, and take the necessary actions to deal with the situation.

GENERAL PRECAUTIONS

Mistakes in operation are extremely dangerous. Read the Operation and Maintenance Manual carefully BEFORE operating the machine.

1.Before carrying out any greasing or repairs, read all the precautions given on the decals which are fixed to the machine.

2.When carrying out any operation, always wear safety shoes and helmet. Do not wear loose work clothes, or clothes with buttons missing.

•Always wear safety glasses when hitting parts with a hammer.

•Always wear safety glasses when grinding parts with a grinder, etc.

3.If welding repairs are needed, always have a trained, experienced welder carry out the work. When carrying out welding work, always wear welding gloves, apron, hand shield, cap and other clothes suited for welding work.

4.When carrying out any operation with two or more workers, always agree on the operating procedure before starting. Always inform your fellow workers before starting any step of the operation. Before starting work, hang UNDER REPAIR signs on the controls in the operator’s compartment.

5.Keep all tools in good condition and learn the correct way to use them.

6.Decide a place in the repair workshop to keep tools and removed parts. Always keep the tools and parts in their correct places. Always keep the work area clean and make sure that there is no dirt or oil on the floor. Smoke only in the areas provided for smoking. Never smoke while working.

PREPARATIONS FOR WORK

7.Before adding oil or making any repairs, park the machine on hard, level ground, and block the wheels or tracks to prevent the machine from moving.

8.Before starting work, lower blade, ripper, bucket or any other work equipment to the ground. If this is not possible, insert the safety pin or use blocks to prevent the work equipment from falling. In addition, be sure to lock all the control levers and hang warning signs on them.

9.When disassembling or assembling, support the machine with blocks, jacks or stands before starting work.

10.Remove all mud and oil from the steps or other places used to get on and off the machine. Always use the handrails, ladders or steps when getting on or off the machine. Never jump on or off the machine. If it is impossible to use the handrails, ladders or steps, use a stand to provide safe footing.

00-3

PRECAUTIONS DURING WORK

11.When removing the oil filler cap, drain plug or hydraulic pressure measuring plugs, loosen them slowly to prevent the oil from spurting out.

Before disconnecting or removing components of the oil, water or air circuits, first remove the pressure completely from the circuit.

12.The water and oil in the circuits are hot when the engine is stopped, so be careful not to get burned.

Wait for the oil and water to cool before carrying out any work on the oil or water circuits.

13.Before starting work, remove the leads from the battery. Always remove the lead from the negative (–) terminal first.

14.When raising heavy components, use a hoist or crane.

Check that the wire rope, chains and hooks are free from damage.

Always use lifting equipment which has ample capacity.

Install the lifting equipment at the correct places. Use a hoist or crane and operate slowly to prevent the component from hitting any other part. Do not work with any part still raised by the hoist or crane.

15.When removing covers which are under internal pressure or under pressure from a spring, always leave two bolts in position on opposite sides. Slowly release the pressure, then slowly loosen the bolts to remove.

16.When removing components, be careful not to break or damage the wiring. Damaged wiring may cause electrical fires.

17.When removing piping, stop the fuel or oil from spilling out. If any fuel or oil drips onto the floor, wipe it up immediately. Fuel or oil on the floor can cause you to slip, or can even start fires.

18.As a general rule, do not use gasoline to wash parts. In particular, use only the minimum of gasoline when washing electrical parts.

19.Be sure to assemble all parts again in their original places.

Replace any damaged parts with new parts.

•When installing hoses and wires, be sure that they will not be damaged by contact with other parts when the machine is being operated.

20.When installing high pressure hoses, make sure that they are not twisted. Damaged tubes are dangerous, so be extremely careful when installing tubes for high pressure circuits. Also, check that connecting parts are correctly installed.

21.When assembling or installing parts, always use the specified tightening torques. When installing protective parts such as guards, or parts which vibrate violently or rotate at high speed, be particularly careful to check that they are installed correctly.

22.When aligning two holes, never insert your fingers or hand. Be careful not to get your fingers caught in a hole.

23.When measuring hydraulic pressure, check that the measuring tool is correctly assembled before taking any measurements.

24.Take care when removing or installing the tracks of track-type machines.

When removing the track, the track separates suddenly, so never let anyone stand at either end of the track.

HOISTING INSTRUCTIONS

HOISTING INSTRUCTIONS

HOISTING

¤Heavy parts (25 kg or more) must be lifted with a hoist, etc. In the DISASSEMBLY AND ASSEMBLY section, every part weighing 25 kg or more is indicated clearly with the symbol 4

•If a part cannot be smoothly removed from the machine by hoisting, the following checks should be made:

1)Check for removal of all bolts fastening the part to the relative parts.

2)Check for existence of another part causing interference with the part to be removed.

WIRE ROPES

1)Use adequate ropes depending on the weight of parts to be hoisted, referring to the table below:

Wire ropes (Standard «Z» or «S» twist ropes

without galvanizing)

The allowable load value is estimated to be onesixth or one-seventh of the breaking strength of the rope used.

2)Sling wire ropes from the middle portion of the hook.

Slinging near the edge of the hook may cause the rope to slip off the hook during hoisting, and a serious accident can result. Hooks have maximum strength at the middle portion.

3)Do not sling a heavy load with one rope alone, but sling with two or more ropes symmetrically wound onto the load.

¤Slinging with one rope may cause turning of the load during hoisting, untwisting of the rope, or slipping of the rope from its original winding position on the load, which can result in a dangerous accident.

4)Do not sling a heavy load with ropes forming a wide hanging angle from the hook.

When hoisting a load with two or more ropes, the force subjected to each rope will increase with the hanging angles. The table below shows the variation of allowable load kN {kg} when hoisting is made with two ropes, each of which is allowed to sling up to 9.8 kN {1000 kg} vertically, at various hanging angles.

When two ropes sling a load vertically, up to 19.6 kN {2000 kg} of total weight can be suspended. This weight becomes 9.8 kN {1000 kg} when two ropes make a 120° hanging angle. On the other hand, two ropes are subjected to an excessive force as large as 39.2 kN {4000 kg} if they sling a 19.6 kN {2000 kg} load at a lifting angle of 150°.

tank.

¤Even if the residual pressure is released from

the hydraulic tank, some hydraulic oil flows out

when the hose is disconnected. Accordingly,

prepare an oil receiving container.

Disconnection

1)Release the residual pressure from the hydraulic tank. For details , see TES TIN G AN D ADJUSTING, Releasing residual pressure from hydraulic tank.

2)Hold adapter (1) and push hose joint (2) into mating adapter (3). (See Fig. 1)

The adapter can be pushed in about 3.5 mm.

Do not hold rubber cap portion (4).

3)After hose joint (2) is pushed into adapter (3), press rubber cap portion (4) against (3) until it clicks. (See Fig. 2)

4)Hold hose adapter (1) or hose (5) and pull it out. (See Fig. 3)

Since some hydraulic oil flows out, prepare an oil receiving container.

Connection

1)Hold hose adapter (1) or hose (5) and insert it in mating adapter (3), aligning them with each other. (See Fig. 4)

Do not hold rubber cap portion (4).

2)After inserting the hose in the mating adapter

perfectly, pull it back to check its connecting condition. (See Fig. 5)

When the hose is pulled back, the rubber cap portion moves toward the hose about 3.5 mm. This does not indicate abnormality, however.

CONVERSION TABLE

CONVERSION TABLE

METHOD OF USING THE CONVERSION TABLE

The Conversion Table in this section is provided to enable simple conversion of figures. For details of the method of using the Conversion Table, see the example given below.

EXAMPLE

•Method of using the Conversion Table to convert from millimeters to inches

1.Convert 55 mm into inches.

(1)Locate the number 50 in the vertical column at the left side, take this as A, then draw a horizontal line from A.

(2)Locate the number 5 in the row across the top, take this as B, then draw a perpendicular line down from B.

(3)Take the point where the two lines cross as C. This point C gives the value when converting from millimeters to inches. Therefore, 55 mm = 2.165 inches.

2.Convert 550 mm into inches.

(1)The number 550 does not appear in the table, so divide by 10 (move the decimal point one place to the left) to convert it to 55 mm.

(2)Carry out the same procedure as above to convert 55 mm to 2.165 inches.

(3)The original value (550 mm) was divided by 10, so multiply 2.165 inches by 10 (move the decimal point one place to the right) to return to the original value. This gives 550 mm = 21.65 inches.

Temperature

Fahrenheit-Centigrade Conversion ; a simple way to convert a Fahrenheit temperature reading into a Centigrade temperature reading or vice versa is to enter the accompanying table in the center or boldface column of figures.

These figures refer to the temperature in either Fahrenheit or Centigrade degrees.

If it is desired to convert from Fahrenheit to Centigrade degrees, consider the center column as a table of Fahrenheit temperatures and read the corresponding Centigrade temperature in the column at the left.

If it is desired to convert from Centigrade to Fahrenheit degrees, consider the center column as a table of Centigrade values, and read the corresponding Fahrenheit temperature on the right.
