• Do not do the procedures below when you start the
engine.
– short across starter terminals
– bypass the safety start switch
• Do not alter or remove any part of machine safety
system.
• Before you start the engine, make sure that all shift
levers are in neutral positions or in disengaged
positions.
• Do not start the engine when you stay on the ground.

INFORMATION
OPERATE SAFELY
• Do not use the machine after you consume alcohol
or medication or when you are tired.
• Put on applicable clothing and safety equipment.
• Use applicable tools only. Do not use alternative
tools or parts.
• When 2 or more persons do servicing, make sure
that you do it safely.
• Do not operate below the machine that only a jack
holds. Always use a safety stand to hold the
machine.
• Do not touch the hot parts or parts that turn when the
engine operates.
• Do not remove the radiator cap when the engine
operates, or immediately after it stops. If not, hot
water can spout out from the radiator. Only remove
the radiator cap when it is at a sufficiently low
temperature to touch with bare hands. Slowly loosen
the cap to release the pressure before you remove it
fully.
• Released fluid (fuel or hydraulic oil) under pressure
can cause damage to the skin and cause serious
injury. Release the pressure before you disconnect
hydraulic or fuel lines. Tighten all connections before
you apply the pressure.
• Do not open a fuel system under high pressure.
The fluid under high pressure that stays in fuel lines
can cause serious injury. Do not disconnect or repair
the fuel lines, sensors, or any other components
between the fuel pump and injectors on engines with
a common rail fuel system under high pressure.
• Put on an applicable ear protective device (earmuffs
or earplugs) to prevent injury against loud noises.
• Be careful about electric shock. The engine
generates a high voltage of more than DC100 V in
the ECU and is applied to the injector.
WSM000001INI0012US0
PREVENT A FIRE
• Fuel is very flammable and explosive under some
conditions. Do not smoke or let flames or sparks in
your work area.
• To prevent sparks from an accidental short circuit,
always disconnect the battery negative cable first
and connect it last.
• The battery gas can cause an explosion. Keep the
sparks and open flame away from the top of battery,
especially when you charge the battery.
• Make sure that you do not spill fuel on the engine.

INFORMATION
KEEP A GOOD AIRFLOW IN THE WORK AREA
• If the engine is in operation, make sure that the area
has good airflow. Do not operate the engine in a
closed area. The exhaust gas contains poisonous
carbon monoxide.
WSM000001INI0006US0
DISCARD FLUIDS CORRECTLY
• Do not discard fluids on the ground, down the drain,
into a stream, pond, or lake. Obey related
environmental protection regulations when you
discard oil, fuel, coolant, electrolyte and other
dangerous waste.
WSM000001INI0007US0
PREVENT ACID BURNS
• Keep electrolyte away from your eyes, hands and
clothing. Sulfuric acid in battery electrolyte is
poisonous and it can burn your skin and clothing and
cause blindness. If you spill electrolyte on yourself,
clean yourself with water, and get medical aid
immediately.
WSM000001INI0008US0
PREPARE FOR EMERGENCIES

2. GENERAL PRECAUTIONS
• When you disassemble, carefully put the parts in a clean area
to make it easy to find the parts. You must install the screws,
bolts and nuts in their initial position to prevent the reassembly
errors.
• When it is necessary to use special tools, use KUBOTA special
tools. Refer to the drawings when you make special tools that
you do not use frequently.
• Before you disassemble or repair machine, make sure that you
always disconnect the ground cable from the battery first.
• Remove oil and dirt from parts before you measure.
• Use only KUBOTA genuine parts for replacement to keep the
machine performance and to make sure of safety.
• You must replace the gaskets and O-rings when you assemble
again. Apply grease (1) to new O-rings or oil seals before you
assemble.
• When you assemble the external or internal snap rings, make
sure that the sharp edge (3) faces against the direction from
which force (2) is applied.
• When inserting spring pins, their splits must face the direction
from which a force is applied. See the figure left side.
• To prevent damage to the hydraulic system, use only specified
fluid or equivalent.
• Clean the parts before you measure them.
• Tighten the fittings to the specified torque. Too much torque can
cause damage to the hydraulic units or the fittings. Not sufficient
torque can cause oil leakage.
• When you use a new hose or pipe, tighten the nuts to the
specified torque. Then loosen (approx. by 45 °) and let them be
stable before you tighten to the specified torque (This is not
applied to the parts with seal tape).
• When you remove the two ends of a pipe, remove the lower end
first.
• Use two pliers in removal and installation. One to hold the stable
side, and the other to turn the side you remove to prevent twists.
• Make sure that the sleeves of flared connectors and tapers of
hoses are free of dust and scratches.
• After you tighten the fittings, clean the joint and apply the
maximum operation pressure 2 to 3 times to examine oil
leakage.

GENERAL
Engine Oil:
• 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:
• 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).
• 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 Oil class of engines with external EGR

(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))

• The CJ-4 engine oil is intended for DPF (Diesel Particulate Filter) type engines, and cannot be used on this
machine.
except external EGR with external EGR
Models GR1600EU, GR1600F, GR1600ID —
Fuel:
• Cetane number of 45 minimum. Cetane number greater than 50 is preferred, especially for temperatures below
−20 °C or elevations above 1500 m.
• 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 %.
• NEVER use diesel fuel with sulfur content greater than 0.05 % (500 ppm) for EXTERNAL EGR type engine.
• DO NOT use diesel fuel with sulfur content greater than 1.0 % (10000 ppm).
• Diesel fuels 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)
Transmission Oil:
*KUBOTA Super UDT-2: For an enhanced ownership experience, we highly recommend Super UDT-2 to be used
instead of standard hydraulic/transmission fluid.
Super UDT-2 is a proprietary KUBOTA formulation that deliveries superior performance and protection in all
operating conditions.
Regular UDT is also permitted for use in this machine.
• Indicated capacities of water and oil are manufacturer's estimate.
