SAFETY PRECAUTIONS FOR PICK & CARRY OPERATION

TRANSPORTATION MEASURE

5.1 LOADING/UNLOADING

• See "Specifications 1. Main Specification Table" for dimensions and weights related to this machine.

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

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

• Has a width no narrower than the rubber tracks.

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

• Be sure to place the ramp boards perpendicular to the truck box.

Also, match the center of the each of the tracks with the center of corresponding ramp board. Misplaced ramp boards and unmatched tracks may cause the machine to slip off of the ramp boards and cause serious accidents.

• Always put the machine in the "travelling posture" when loading/unloading the machine.

See "Operation 3.6 Machine Travelling Posture" for information about the travelling posture.

• Always run the engine at low idling speed, and operate the machine slowly when loading and unloading.

• 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 forward involves overturning hazard. The operator must be on the back side of the truck.

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

• Select flat and solid ground for loading/unloading the machine.

Maintain a safe distance from the edge of the road.

• Remove dirt around the crawlers to prevent the machine from slipping sideways on the ramp boards.

Remove any substance on the loading ramps such as snow, ice, grease, and oil.

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

• The center of gravity of the machine will change suddenly at the point between the ramps and the trailer, and there is a danger that the machine will go off balance. Travel slowly over this point.

Always put the machine in the "travelling posture" when loading/unloading the machine. Always use ramp boards or forwarding blocks when loading/unloading the machine and use the following procedure.

5.1.1 LOADING

1. Load and unload on firm level ground only. Maintain a safe distance from the edge of a road.

2. Apply the trailer brakes securely, then put blocks under the tires to prevent the trailer from moving.

3. Secure the ramp boards in a way that the center of the trailer and the machine match.

NOTES

• Set left and right ramps parallel to each other and equally spaced to the left and right of center of the trailer.

• Make angle of installation a maximum of 15 degrees.

• Hang the hook of the ramp securely to hook the holder of the trailer.

• If the ramps bend by a large extent due to the weight of the machine, put blocks under the ramps to prevent them from bending.

4. Start the engine.

Warm the engine up fully.

5. Set the lock lever to FREE position (F).

6. Keep the engine speed at a low idle.

7. Do not operate the travel speed-up pedal.

8. Before moving onto the ramps, make sure that the machine is positioned in a straight line with the ramps and that the center line of the machine matches that of the trailer.

Align the direction of travel with the ramps and travel slowly.

Only operate the travel lever while on the ramps. Do

9. Align the direction of travel with the ramps and travel slowly. When on the ramps, operate only the travel.

10. When the machine travels over the rear wheels of the trailer, it becomes unstable, so drive slowly and carefully. Never operate the steering.

11. At the moment the machine passes the rear wheels, it tilts backward, so be careful not to let the crane hit the trailer body, drive the machine backward to the specified position, then stop the machine.

5.1.2 SECURING MACHINE

After placing the machine on the specified position of the trailer, secure it according to the following procedure.

1. Lower the blade.

2. Stop the engine, and remove the key from the starter switch.

3. Set the lock lever securely to the LOCK position (L).

CAUTION

Do not use the fixing hole at the rear of the track frame for towing or lifting the machine.

4. Place blocks under both ends of the tracks to prevent the machine from moving during transportation, and secure the machine with chains or wire cables of suitable strength.

Be particularly careful to secure the machine in position so that it does not slip to the side.

NOTES

• When securing the machine, put blocks between the wire cable and the machine to prevent damage to the cable or machine.

• When using chains or wire cables to secure the machine, utilize the holes on the blade side plate and the fixing hole at the rear of the track frame.

5.1.3 UNLOADING

1. Unload on firm level ground only. Maintain a safe distance from the edge of a road.

2. Apply the trailer brakes securely, then put blocks under the tires to prevent the trailer from moving.

3. Secure the ramp boards in a way that the center of the trailer and the machine match.

NOTES

• Set the left and right ramps parallel to each other and equally spaced to the left and right of the center of the trailer.

• Set the angle of installation to a maximum of 15 degrees.

• Hang the hook of the ramp securely to the hook holder of the trailer.

• If the ramps bend a large amount under the weight of the machine, put blocks under the ramps to prevent them from bending.

4. Remove the chains and wire cables fastening the machine.

5. Start the engine.

Warm the engine up fully.

6. Set the lock lever to the FREE position (F).

7. Keep the engine speed at a low idle.

8. Do not operate the travel speed-up pedal.

9. Before moving onto the ramps, make sure that the machine is positioned in a straight line with the ramps and that the center line of the machine matches that of the trailer.

Align the direction of travel with the ramps and travel slowly.

Only operate the travel lever while on the ramps. Do not operate any other lever.
