appropriate to the job.

• Use tools appropriate to the work. Makeshift tools,
parts, and procedures are not recommended.

• When servicing is performed together by two or more
persons, take care to perform all work safely.

• Do not work under the machine that is supported
solely by a jack. Always support the machine by
safety stands.

• Do not touch the rotating or hot parts while the engine
is running.

• Never remove the radiator cap while the engine is
running, or immediately after stopping. Otherwise, hot
water will spout out from radiator. Only remove
radiator cap when cool enough to touch with bare
hands. Slowly loosen the cap to first stop to relieve
pressure before removing completely.

• Escaping fluid (fuel or hydraulic oil) un der pressure
can penetrate the skin causing serious injury. Relieve
pressure before disconnecting hydraulic or fuel lines.
Tighten all connections before applying pressure.

• Do not open high-pressure fuel system.
High-pressure fluid remai ning in fuel lines can cause
serious injury. Do not disconnect or attempt to repair
fuel lines, sensors, or any other components between
the high-pre ssur e fuel pu mp and inje ctors on engin es
with high pressure common rail fuel system.

SAFETY INSTRUCTIONS

AVOID FIRES

• Fuel is extremely flammable and explosive under
certain conditions. Do not smoke or allow flames or
sparks in your working area.

• To avoid sparks from an accidental short circuit,
always disconnect the battery negative cable first and
connect it last.

• Battery gas can explode. Keep sparks and open
flame away from the top of batt ery, especially when
charging the battery.

• Make sure that no fuel has been spilled on the engine.

VENTILATE WORK AREA

• If the engine must be running to do some work, make
sure the area is well ventilated . Neve r run the eng ine
in a closed area. The exhaust gas contains poisonous
carbon monoxide.

PREVENT ACID BURNS

• Sulfuric acid in batte ry electrolyte is poisonou s. It is
strong enough to burn skin, clothing and cause
blindness if splashed into eyes. Keep electrolyte
away from eyes, hands and clothing. If you spill
electrolyte on yourself, flush with water, and get
medical attention i mmediately.

DISPOSE OF FLUIDS PROPERLY

• Do not pour fluids into the ground, down a drain, or
into a stream, pond, or lake. Observe relevant
environmental prot ectio n regulati ons whe n disp osing
of oil, fuel, coolant, electrolyte and other harmful
waste.

G GENERAL

• Engine Oil:

• Oil used in th e engine should ha ve an Am erican Petroleum Institute ( API) ser vice cl assificati on and Pr oper SAE
Engine Oil according to the ambient temperature as shown in the table.

• With the emission control now in effect, the CF-4 and CG-4 lubricating oils have been developed for use of a low­sulfur fuel on on-roa d v ehi cl e e ngi nes . When an off-road vehicle eng ine r uns on a hi gh- s ulf ur fuel , i t is ad vi sa ble
to employ the "CF or better" lubricating oil with a high Total Base Number (TBN of 10 minimum).

• Lubricating oil recommended when a low-sulfur or high-sulfur fuel is employed.

• Recommended API categorization

■ Fuel

• Cetane number of 45 minimum. Cetane number greater than 50 is preferred, especially for temperature below

-20 °C (-4 °F) or elevations above 1500 m (5000 ft).

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

• DO NOT use diesel fuel with sulfur content greater than 1.0 %.

• Diesel fuel specified to EN 590 or ASTM D975 are recommended.

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

• Since this engine adopts EPA Tier 4 and Interim Tier 4 standards, the use of low sulfur fuel or ultra low sulfur fuel
is mandatory in E PA regulated are a (North Ame rica). Therefo re, p lease use No. 2-D S500 or S 15 dies el fue l as
an alternative to No. 2-D, or use No.1-D S500 or S15 diesel fuel as an alternative to No.1-D if outside air
temperature is below -10 °C (14 °F).

■ 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 recomme nded the use of KUBOTA UDT or SUPER UDT fluid for optimum protection and
performance.
Do not mix different brands together.

• Indicated capacities of water and oil are manufacture’s estimate.
