TRAVELING ON SLOPES

Warning

● When traveling, raise the bucket approx. 40 to 50cm from the ground.

● Do not travel downhill in reverse.

● When traveling over ridges or other obstacles, keep the work equipment close to the ground and travel slowly.

● Never turn on slopes or travel across slopes. Always go down to a flat place to perform these operations. It may be longer, but it will ensure safety.

● Always operate or travel in such a way that it is possible to stop safely at any time if the machine slips or becomes unstable.

● Turning or operating the work equipment when working on slopes may cause the machine to lose it balance and turn over, so avoid such operations. It is particularly dangerous to swing downhill when the bucket is loaded.

If such operations have to be carried out, pile soil to make a platform on the slope so that the machine can be kept horizontal when operating.

● Do not travel up or down steep slopes. There is danger that the machine may turn over.

● When traveling uphill, if the shoes slip or it is impossible to travel uphill using only the force of the tracks, do not use the pulling force of the arm to help the machine travel uphill. There is danger that the machine may turn over.

1.When traveling down steep hills, use the travel lever and fuel control lever to keep the travel speed low. When traveling down a steep hill of more than 15°, set the work equipment to the posture shown in the diagram on the right, and lower the engine speed.

2.When traveling up a steep hill of more than 15º, set the work equipment to the posture shown in the diagram on the right.

Traveling Downhill

To brake the machine during downhill runs, put the travel lever in the neutral position. This will cause the brake to be automatically applied.

Engine Stopped On Slope

If the engine stops when traveling uphill, move the all levers to the neutral position, then start the engine again.

Precautions On Slopes

● If the engine stops when the machine is on a slope, never use the left work equipment control lever to carry out swing operations. The upper structure will swing under its own weight.

● Be extremely careful when opening or closing the door on slopes. The weight of the door may cause the door to open or close suddenly. Always set the door so that it is firmly locked in position.

Escape From Mud

Always operate carefully to avoid getting stuck in mud. If the machine does get stuck in mud, use the following procedures to get the machine out. Be careful not to get stuck in mud when operating. If you do get stuck in mud, do as follows to escape.

● Place the machine push-up switch (1) at position. This will increase the pushing power of the boom and make it easier to escape.

Stuck One Side Of Track Notice

When using the boom or arm to raise the machine, always have the bottom of the bucket in contact with the ground. (Never push with the teeth). The angle between the boom and arm should be 90° to 110°. The same applies when using the inverting bucket.

When only one side is stuck in mud, use the bucket to raise the track, then lay boards or logs and drive the machine out. If necessary, put a board under the bucket also.

Stuck Both Sides Of Tracks

If the track on both sides are in mud and the machine slips and cannot move, use the procedure given above to lay logs or timber. Dig the bucket into the ground at the front, operate the arm in the same way as when digging, and set the travel lever to FORWARD to pull the machine out.

Recommended Applications

In addition to the following, it is possible to further increase the range of applications by using various attachments.

Backhoe Work

A backhoe is suitable for excavating at a position lower than the machine.

When the condition of the machine is as shown in the diagram at right, each cylinder's maximum pushing excavation force is obtained when the bucket cylinder and link, arm cylinder and arm are at 90°.

When excavating, use this angle effectively to optimize your work efficiency.

The range for excavating with the arm is from a 45° angle away from the machine to a 30° angle toward the machine.

There may be some differences depending on the excavation depth, but try to stay within the above range rather than operating the cylinder is the end of its stroke.

Loading Work

In places where the swing angle is small, work can be carried out more efficiently by stopping the dump truck in a place where it can be seen easily by the operator.

Loading is easier and the capacity is greater if you load from the rear of the dump truck body than if you load from the side.

Replacement And Inversion Of Bucket Warning

● When the pin is knocked in with a hammer, pieces of metal may fly into your eyes and cause serious injury.

When carrying out this operation, always wear goggles, hard hat, gloves, and other protective equipment.

● When the bucket is removed, place it in a stable condition.

● If the pins are hit with force, the pin may fly and injure people in the surrounding area, so check that the surrounding area is safe.

● When removing the pin, be extremely careful not to stand behind the bucket or to put your foot or any part of your body behind the bucket from the side.

● When removing or installing the pin, be extremely careful not to get your hands caught.

● Never put your fingers in the pin holes when aligning the holes.

Stop the machine on a firm, flat surface. When performing joint work, make clear signals to each other and work carefully for safety's sake.

Replacement

1.Place the bucket in contact with a flat surface.

Notice

When removing the bucket, set the bucket cylinder facing down as shown in the diagram in the right to prevent the front link from jumping up under the weight of the bucket cylinder.

Remark

When removing the pins, place the bucket so that it is in light contact with the ground. If the bucket is lowered strongly to the ground, the resistance will be increased and it will be difficult to remove the pins.

2.Remove pin (1) from the arm mounting hole and pin (2) from the link mounting hole, then remove the bucket.

● Remove stopper bolts (3 each, 2 places) at portion (T) on the inside of the arm and 2 stoppers, remove stopper bolts (6 each, 2 places) at portion (S) on the outside of the arm, then remove pin (1).

● Remove stopper bolts (3 each, 2 places) at portion (T) on the inside of the link and 2 stoppers, and install bolts (3 each, 2 places) in the forcing tap holes at portion (S) on the outside of the link, then remove pin (2).

Notice

After removing the pins, be careful not to let any sand or mud get on them. In addition, seals are fitted at both ends of the bushing, so be careful not to damage them.

3.Align the arm with hole (A), align the link with hole (B), then coat pins (1) and (2) with the grease, and install them.

Remark

● Carry out installation in the reverse order to removal.

● When installing the bucket, the O-ring can easily be damaged, so fit the O-ring into the groove for bushing (a) at the bucket end (E). After installing the pin, fit it into the specified groove (b).

● After installing the stopper bolt, stopper, collar, and cover for each pin, coat the pins with grease.
