OPERATING MACHINE

d WARNING: When locking the loader control lever and the auxiliary control lever (3) (optional), securely shift lever locks (2), (4) to the LOCK position. Unless lever locks (2), (4) are fully moved to the LOCK position, the control levers are not locked, possibly creating a hazardous situation.

Before leaving the operator’s seat, be sure to stop the engine. Then, move lever locks (2), (4) to the LOCK position.

After completing operation of the machine or transporting the machine, be sure to move lever locks to the LOCK position.

Lever locks (2), (4) are provided to prevent the machine is unexpectedly operated even if the operator mistakenly comes in contact with loader control lever (1) or auxiliary control lever (3) (if equipped) when getting on or off the machine. When loader control lever (1) and auxiliary control lever (3) (optional) is placed to the UNLOCK position, the levers becomes operable.

fNOTE: Auxiliary control lever (3) and lever lock (4) are optional.

Loader Control Lever Lock Operation

• When leaving the operator’s seat:

1. Park the machine on solid level ground. Lower the bucket to the ground. Return all levers to neutral. Stop the engine.

2. Be sure to move lever lock (2) in the LOCK position. Be sure to place lever lock (4) in the LOCK position when auxiliary control lever (3) is not in use.

• Before starting operation: Before starting operation, check that lever lock (2) is in the UNLOCK position.

Be sure to place lever lock (4) in the UNLOCK position when auxiliary control lever (3) is in use.

Adjustment of Bucket Auto Leveler

dWARNING: Pay attention to safety to avoid personal injury and/or death when adjusting the bucket auto leveler. Stop the engine. Lower the loader front attachment to the ground to release the remaining pressure in the hydraulic circuits. Apply the parking brake to prevent the machine from moving unexpectedly. Wedge the wheels with blocks. Keep bystanders away from the vicinity of the machine.

The bucket auto leveler automatically stops the bucket movement at the preset digging angle. (When the machine is shipped from the factory, the bucket positioner is preset so that the bucket is stopped with the bucket bottom parallel with the road surface.)

For example, after discharging the handling materials onto a truck or into a hopper, when loader control lever (4) is placed to detent position (G), the lever is held in that position. Then, when the bucket is returned to the preset angle position, the bucket is automatically stopped and the lever is returned to neutral (N).

The bucket auto leveler is preset so that the bucket is stopped when the bucket bottom becomes parallel with the road surface. Nevertheless, when tilting the bucket forward or backward more than the preset level position is needed, adjust the mounting position of the auto leveler proximity switch.

Adjustment Procedures

IMPORTANT: Do not operate the machine with the bucket dumped more than 10 degrees. Avoid applying great towing force to the bucket cutting edge.

1. After moving the bucket to the desired digging angle, stop the engine.

2. Loosen lock nuts (2) (2 used) of proximity switch mounting bracket (1). Slide bracket (1) up to the end edge of leveler bar (3) moves to the center of the sensitive area (orange color) (5). Then, tighten lock nuts (2) (2 used).

3. After adjustment start the engine. Check that the bucket can be stopped at the preset angle position.
