3.3 PROHIBITIONS AND CAUTIONS WHEN USING RUBBER TRACKS

Not observing these cautions in using rubber tracks will cause serious accidents or damage to the rubber tracks.

Keep the followings in mind during the operation.

• Working and slewing on the ground with broken stones, hard rock ground with great irregularity, reinforcing steels, iron scraps, and near the edge of the steel plates will damage the rubber tracks.

• Working where there is a large amount of large and small boulder stones such as river beds, the stones will go under the machine, tending to damage the rubber tracks or the rubber tracks tend to come off.

• Keep oil and chemical solvents away from the rubber tracks. If these materials come in contact with the rubber tracks, wipe it off immediately.

Do not TRAVEL over the road surface where oil has built up.

• Do not go in an area where it is hot, such as with open fire, the steel plate left under the burning sun, or newly poured asphalt.

• Avoid making spin turns on the concrete surface. Sudden steering cause’s early wear or defects to the rubber tracks. Avoid making sudden steering whenever possible.

• Do not operate the machine in a way that the edge of the rubber tracks is pressed against concrete and walls.

• Avoid steering at the location with a large step. Ensure the machine is perpendicular to the step when going over it.Going over the step diagonally may result in the rubber tracks coming off.

• Avoid using the rubber tracks whenever possible depending on the material to be worked on.

If you have to use the rubber tracks on these materials, wash thoroughly with water after use.

• Avoid the operation on crushed material and yielding oil (such as soy beans, corns, rape cake, etc.)

• Handling salt, ammonium sulfate, potassium chloride, or concentrated superphosphate corrodes the bonding at the cored bar section.

• Salt corrodes the bonding at the cored bar section. Avoid using the machine on the beach whenever possible.

• Operation in extreme cold changes the material of the rubber tracks, shortening its life.

Use the rubber tracks in the range of -25°C to + 55°C, due to the physical properties of the rubber.

• When handling food such as salt, sugar, wheat, and soybeans, some pieces of wire or rubber may be mixed in the food if there is any deep scratch on the rubber tracks. Use the rubber tracks after repairing the cracked rubber.

• The rubber tracks slip very easily on a wet steep plate or snowed and frozen surface. Be especially careful not to slip when operating on the slope.

• Always use the rubber tracks at appropriate tension to prevent the rubber track from coming off. Loose tension will allow the rubber tracks to come off.

• Keep the rubber tracks indoors away from direct sunlight or rain when storing them for a long time (three months or more).

4. WHAT TO DO WITH TWISTED WINCH WIRE ROPE

Be sure to wear a pair of thick leather working gloves when handling wire ropes.

Caution

Change the winding direction of the wire rope (reverse the hook block side and winch drum side) from time to time to extend the life of the wire rope.

When the wire rope becomes twisted, straighten the twist with the following procedure.

1. With the hook in normal condition, check the twisting direction and how many times the rope is twisted.

2. Operate the winch lever to “DOWN” (push forward) side to lower the hook block onto the ground. If the hook cannot be lowered, operate the boom derricking lever to the “LOWER” (push forward) side to lower the boom or operate the boom telescoping lever to the “RETRACT” (pull toward you) side to retract the boom to lower the boom.

3. Push down the auxiliary starter switch to the STOP position to stop the engine.

4. Remove the wedge socket pin securing bolt (3) to remove the wedge socket (2)

5. Forcibly twist the end of the wire for “n” (number of wire falls) times the number that the hook has twisted, in the opposite direction from the direction the hook block is twisted to - which you checked in the step 1 (opposite direction that the wire rope tries to go back to naturally when you release your hand from the wedge socket) and install the wire rope.

6. Start the engine and operate the boom derricking lever to the ”RAISE” (pull toward you) side to increase the boom angle to its maximum.

7. Operate the boom telescoping lever to the “EXTEND” (push forward) side to extend the boom to its maximum.

8. Operate the winch lever to repeat raising/lowering the hook block for several times.

9. Tidily spool up the wire rope into the winch drum with some tension applied to the rope.

10. Repeat the above procedure until the hook is longer twisted.

If the wire rope is still twisted after performing the procedure above, change with a new wire rope.

5. TRANSPORTATION

Observe the related laws and regulations and transport the machine safely.

5.1 LOADING/UNLOADING

• See "Specifications 1.1 Specification List " in the Dimension for the dimensions and mass of the machine.

• Select and use the ramp boards that satisfy the following conditions.

• Has the length that when placed, the angle from the track is 15 degrees or less.

• Has the width no narrower than the rubber tracks.

• Has the thickness and strength that can fully withstand the mass of the machine.

• Be sure to place the ramp boards perpendicular to the truck bed. Also, match the centre of the each of the rubber tracks with the centre of corresponding ramp board. Misguided ramp boards and unmatched rubber crawlers may cause the machine to slip out of the ramp boards and cause serious accidents.

• Use ramp boards with slope of 15 degrees or less. The space between boards shall be set to be appropriate to the centre of the rubber tracks.

• Always put the machine in the “Travelling position” when loading/unloading the machine. See “Operation 2.5 Machine Travelling Position” for travelling position.

• Always load the machine by moving backward. Moving forward involves overturning hazard. The operator must be on the back side of the truck.

• Always unload the machine by moving forward. Moving backward risks overturning. The operator must be behind the machine

• Loading/Unloading the machine involves danger. Be extremely careful.

• Select flat and solid ground for loading/unloading the machine. Keep sufficient distance from the shoulders.

• Remove dirt around the crawlers to prevent side slip of the machine on the ramp boards. Remove any materials on the loading ramps such as ice, grease, and oil.

• Never change direction on the ramp boards. Go down from the ramp board, and then change the direction.

Always put the machine in the “Travelling position” when loading/unloading the machine. Always use ramp boards or forwarding blocks when loading/unloading the machine and use the following procedure.

1. Brake the trailer securely. Place wheel blocks to the wheels of the trailer to secure the trailer.

2. Secure the ramp boards in a way that the centre of the trailer and the machine agree.

Notes

Verify that the two ramp boards are at the same height.

3. Operate the acceleration lever and keep the engine at low speed.

4. TRAVEL slowly toward the ramp boards, and load/unload the machine in a way that the boom does not hit the trailer. Move backward to load the machine, and forward to unload the machine.

5. Do not operate any other lever than travelling levers on the ramp boards.

6. Load the machine properly to the desired position on the trailer.
