OPERATING THE BACKHOE

A

Always lower stabilizers slightly when changing from
one position to another to avoid soil splash.

TRANSPORTING

To avoid personal injury:

A

Before transporting the machine, raise and center
the boom, close the dipperstick, curl the bucket
and engage the boom and swing locks.

A

Always securely fasten the tractor / loader  /
backhoe, with chains and chain binders, to
transport vehicle.  
Determine and note the load height of the
backhoe, for underpass clearance, before
transporting.

B

Driving to the Job-site

When driving or transporting from one job-site to another,
or when using the loader such as stockpiling and
backfilling, always engage the boom and swing locks.

B

Trailer Transporting

When loading or off-loading the machine on or from trailer
/ truck, use strong, secure ramps long enough to provide
a low angle to the transport vehicle.
After loading the machine, release the boom lock, lower
the backhoe bucket to the bed of the transport vehicle,
lower the loader bucket, set the parking brake of the
tractor, shut the engine off and then remove the key.
Check the hood for proper securement, and remove SMV
sign from holder driving transport to avoid damage,
reinstall after transport.
Check the local codes or regulations that may apply to
tractor / loader / backhoe operation on public streets or
highways, before transporting or traveling. Use SMV
emblem and warning flashers as required.

MAINTENANCE OF THE TRACTOR

A

The jobs indicated by  

must be done after the first 50 hours of operation.

*1 Air cleaner should be cleaned more often in dusty conditions than in normal conditions.
*2 Every year or every 6 times of cleaning.
*3 Replace only if necessary.
*4 Consult your local KUBOTA Dealer for this service.
*5 When the battery is used for less than 100 hours per year, check the battery condition by reading the indicator annually.

LUBRICANTS, FUEL AND COOLANT

Note *1 Oil amount when the oil level is at the upper level of the oil level gauge.
         *2 The product name of KUBOTA genuine UDT fluid may be different from that in the Operator's Manual depending 
             on countries or territories. Consult your local KUBOTA Dealer for further detail.

A

To prevent serious damage to hydraulic systems, use only KUBOTA genuine fluid or its equivalent.

MAINTENANCE OF THE TRACTOR

C

Engine Oil:
A

Oil used in the engine should have an American Petroleum Institute (API) service classification and Proper SAE
Engine Oil according to the ambient temperatures as shown above:

A

With the emission control now in effect, the CF-4 and CG-4 lubricating oils have been developed for use of a low-
sulfur fuel on on-road vehicle engines. When an off-road vehicle engine runs on a high-sulfur fuel, it is advisable to
employ the "CF or better" lubricating oil with a high Total Base Number (TBN of 10 minimum).

C

Fuel:
A

Cetane number of 45 is minimum. Cetane number greater than 50 is preferred, especially for temperatures below 
-20

 or elevations above 1500 m.

A

If diesel fuel with sulfur content greater than 0.5% (5000 ppm) sulfur content is used, reduce the service interval for
engine oil and filter by 50%.

A

NEVER use diesel fuel with sulfur content greater than 0.05% (500 ppm) for EXTERNAL EGR type engine.

A

DO NOT use diesel fuel with sulfur content greater than 1.0% (10000 ppm).

A

Diesel fuels specified to EN 590 or ASTM D975 are recommended.

A

No.2-D is a distillate fuel of lower volatility for engines in industrial and heavy mobile service. (SAE J313 JUN87)

C

Transmission Oil:
The oil used to lubricate the transmission is also used as hydraulic fluid. To insure proper operation of the hydraulic
system and to complete lubrication of the transmission, it is important that a multi-grade transmission fluid is used in
this system. We recommend the use of KUBOTA UDT or SUPER UDT fluid for optimum protection and performance.
(Consult your local KUBOTA Dealer for further detail.)
Do not mix different brands together.

A

Indicated capacities of water and oil are manufacturer's estimate.

A

Refer to the following table for the suitable API classification engine oil according to the engine type (with internal
EGR, external EGR or non-EGR) and the fuel (low-sulfur or high-sulfur fuel).

Fuel used

Engine oil classification (API classification)

Oil class of engines except external EGR

[

0.05% (500 ppm)]

CF
(If the "CF-4, CG-4, CH-4 or CI-4" lubricating oil is 
used with a high-sulfur fuel, change the lubricating 
oil at shorter intervals. (approximately half))

---

Low Sulfur Fuel
[<0.05% (500 ppm)] or
Ultra Low Sulfur Fuel

The CJ-4 engine oil is intended for DPF (Diesel Particulate Filter) type engines, and cannot be used on this tractor.
