OPERATING THE LOADER

LOADING LOW TRUCKS OR SPREADERS 

FROM A PILE

For faster loading, minimize the angle of turn and length
of run between pile and spreader.

Back grade occasionally with a loaded bucket to keep the
work surface free of ruts and holes. Also, hold the lift
control forward so the full weight of the bucket is scraping
the ground. Use the heel of the bucket.

BACKFILLING

Approach the pile with the bucket flat.

Poor operating methods will move less dirt and make it
more difficult to hold a level grade.

A

Do not use the bucket in the dumped position for
bulldozing. As shown above, this method will impose
severe shock loads on the dump-linkage, the bucket
cylinders, and the tractor. 

Leave dirt in the bucket because dumping on each pass
wastes time.

Operate at right angles to the ditch. Taking as big a bite
as the tractor can handle.

Leave dirt which drifts over the side of the bucket for final
cleanup.

Pile dirt on the high side for easier backfilling on a slope.

HANDLING LARGE HEAVY OBJECTS

To avoid serious personal injury or death:
A

Handling large, heavy objects can be
dangerous due to :
(A) Danger of rolling the tractor over.
(B) Danger of upending the tractor.
(C) Danger of the object rolling or sliding down
      the loader boom onto the operator.

A

If you must perform the above work, protect
yourself by :
(A) Not lifting the load higher than necessary to
      clear the ground when moving.
(B) Ensuring the approved counter weight is 
      fitted.
(C) Not lifting large objects with equipment that 
      does not have an anti-rollback device.
(D) Moving slowly and carefully.
(E) Avoiding rough terrain.
(F) Keeping transport distance as short as
      possible and carry the load as low as
      possible during transport.
(G) Ensuring that the ROL for the given
      attachment is not exceeded.

VALVE LOCK

To avoid injury from crushing:
A

Do not utilize the valve lock for machine
maintenance or repair.

A

The valve lock is to prevent accidental
actuation when implement is not in use or
during transport.

The control valve is equipped with a valve lock feature.
The control valve is locked in "NEUTRAL" position.
The lock is not intended and will not prevent a leak down
of the implement during the period of storage.

SPILL GUARD (SPILL GUARD MODEL 

ONLY)

The spill guard system prevents the object in the bucket
from falling to the operator’s space.
When the operator operates the control lever to the roll
back position at the upper most boom position, this
system restricts the bucket roll back movement.

A

Check the motion of spill guard function, before
operating the loader.

During operation, the spill guard will operate from the
point equal to or higher than height (L).

B

Adjustment of spill guard link

To avoid personal injury:
A

Keep your hand away from links or boom when
operating the loader.

1. Start engine and lift the boom to appointed height (L).
2. Rolled back the bucket fully and check the rollback

angle (A).

3. If the rollback angle is not the same as following

illustration, adjust the length of connecting rod.

C

Adjustment of spill guard link

1. Remove the cotter pin.
2. Remove the rod from the link.
3. Unfasten the lock nut and adjust the length of

connecting rod by turning rod.

4. Tighten the lock nut and set the rod to the link with the
