PRE-OPERATION CHECK OF THE LOADER

RATED OPERATING LOAD  (SPILL GUARD MODEL ONLY)

To avoid personal injury or death:
A

Do not exceed ROL (Rated operation load).

A

Do not operate the loader without counter weight.

A

Do not exceed 10 km/h when travelling with load.

A

Use only tires approved by Kubota for loader use.

A

ROL is calculated with standard bucket. Optional attachments (4IN1 bucket etc.) will reduce ROL.

A

ROL is determined with the tractor static, on a hard level surface. Reduce load from the listed ROL if
operating on uneven or sloping terrain.

A

Remove the mid mount mower deck (if fitted) before operating the loader.

TIRE INFLATION

Insure that the tractor tires are properly inflated.
See "TIRES, WHEELS AND BALLAST" section.

TEST OPERATION

To avoid serious personal injury:
A

Keep engine speed at low idle during the test
operation.

A

Escaping hydraulic fluid under pressure can
have sufficient force to penetrate skin, causing
serious personal injury.
Before disconnecting lines, be sure to relieve
all pressure by moving the controls.
Before applying pressure to the system, be
sure all connections are tight and that lines,
tubes and hoses are not damaged.
Fluid escaping from a very small hole can be
almost invisible. Use a piece of cardboard or
wood, rather than your hands to search for
suspected leaks.
If injured by escaping fluid, see a doctor at
once. Serious infection or allergic reaction will
develop if proper medical treatment is not
administered immediately.

A

When the lever is at each corner position marked by
asterisk (*), boom and bucket cylinders work at the
same time. However, the blank position (Raise & Roll
back) is not recommended for scooping because of
insufficient lift force.

To begin test operation, slightly move the control lever
from "N" position. Slowly raise the loader boom just
enough for the bucket to clear the ground when fully
dumped. Slowly work through the dump and roll back
cycles.

A

If the boom or bucket does not work in the directions
indicated on the label, lower the bucket to the ground,
stop the engine, and relieve all hydraulic pressure.
Recheck and correct all hydraulic connections.

This control valve has 2 stage dump positions. The first
"Regenerative" dump position, activated by moving the
lever to the right, features high speed for efficient normal
loader operations.
The second "Regular" dump position, activated by moving
the lever further to the right, features increased power.
This second position should be used when operating
implements other than the loader with this control valve.
These 2 positions are separated by a "Feel" position for
your convenience.

REMOVING AIR FROM HYDRAULIC 

SYSTEM

Repeat raising and lowering the boom and bucket
operations until all the air is removed from the system and
the system responds properly.

A

Do not move the control lever into float position when
the bucket is off the ground.

PRE-OPERATION CHECK OF THE BACKHOE

PRE-OPERATION CHECK OF THE BACKHOE

PRE-OPERATION CHECKS

Prior to starting the engine, make pre-operation checks
according to "MAINTENANCE OF THE BACKHOE"
section.

To avoid personal injury:
A

Read " SAFE OPERATION " section in the front
of this manual.

A

Read the warning and caution labels located on
the backhoe.

A

Make sure the swing lock pin is set before
entering or exiting the backhoe operator area.

OPERATOR'S SEAT

Operator's seat for the BX25DLB-AU tractor can be used
to operate loader and backhoe. See "OPERATING THE
TRACTOR" section for the detail to turn the seat around
for backhoe operation. When operating backhoe, the seat
belt should be used.

B

Seat Belt

To avoid personal injury:
A

Always use the seat belt when the ROPS is
installed.
Do not use the seat belt if a foldable ROPS is
down or there is no ROPS.

Adjust the seat belt for proper fit and connect to the
buckle. The seat belt is auto-locking retractable type.

BALLAST

To avoid serious personal injury or death:
A

Never remove loader to ensure tractor stability
at all times.

A

Do not add liquid ballast or any other weights to the
front tires.

A

While BT602 backhoe is installed on the tractor, liquid
ballast in the rear tires should be removed.

TIRE INFLATION

Insure that the tractor tires are properly inflated.
See "TIRES, WHEELS AND BALLAST" section.
