SAFETY INSTRUCTIONS
BEFORE SERVICING AND REPAIRING
• Read all instructions including safety instructions in
this manual and your machine safety decals.
• Clean the work area and machine.
• Park the machine on firm and level ground, and set
the parking brake.
• Lower the implement to the ground.
• Stop the engine, and remove the key.
• Disconnect the battery negative cable.
• Hang a “DO NOT OPERATE” tag on the operators
platform.

F2880, F3680, RCK72-F36, RCK72R-F36, RCK60-F36, RCK60R-F36, WSM SAFETY INSTRUCTIONS
SAFETY STARTING
• Do not start the engine by shorting across starter
terminals or bypassing the safety start switch.
• Do not alter or remove any part of machine safety
system.
• Before starting the engine, make sure that all shift
levers are in neutral positions or in disengaged
positions.
• Never start the engine while standing on the ground.
Start the engine only from operator’s seat.
SAFETY WORKING
• Do not work on the machine while under the influence
of alcohol, medication, or other substances or while
fatigued.
• Wear close fitting clothing and safety equipment
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) under pressure
can penetrate the skin causing serious injury. Relieve
pressure before disconnecting hydraulic or fuel lines.
Tighten all connections before applying pressure.
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 battery, especially when
charging the battery.
• Make sure that no fuel has been spilled on the engine.

F2880, F3680, RCK72-F36, RCK72R-F36, RCK60-F36, RCK60R-F36, WSM SAFETY INSTRUCTIONS
VENTILATE WORK AREA
• If the engine must be running to do some work, make
sure the area is well ventilated. Never run the engine
in a closed area. The exhaust gas contains poisonous
carbon monoxide.
PREVENT ACID BURNS
• Sulfuric acid in battery electrolyte is poisonous. 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 immediately.
DISPOSE OF FLUIDS PROPERLY
• Do not pour fluids into the ground, down a drain, or
into a stream, pond, or lake. Observe relevant
environmental protection regulations when disposing
of oil, fuel, coolant, electrolyte and other harmful
waste.
PREPARE FOR EMERGENCIES
• Keep a first aid kit and fire extinguisher handy at all
times.
• Keep emergency numbers for doctors, ambulance
service, hospital and fire department near your
telephone.

2. GENERAL PRECAUTIONS
• During disassembly, carefully arrange removed parts in a clean
area to prevent confusion later. Screws, bolts and nuts should be
installed in their original position to prevent reassembly errors.
• When special tools are required, use KUBOTA genuine special
tools. Special tools which are not frequently used should be
made according to the drawings provided.
• Before disassembling or servicing electrical wires, always
disconnect the ground cable from the battery first.
• Remove oil and dirt from parts before measuring.
• Use only KUBOTA genuine parts for parts replacement to
maintain machine performance and to assure safety.
• Gaskets and O-rings must be replaced during reassembly.
Apply grease to new O-rings or oil seals before assembling.
See the figure left side.
• When reassembling external snap rings or internal snap rings,
they must be positioned so that sharp edge faces against the
direction from which a force is applied. See the figure left side.
• 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.

3. HANDLING PRECAUTIONS FOR ELECTRICAL PARTS
AND WIRING
To ensure safety and prevent damage to the machine and
surrounding equipment, heed the following precautions in handling
electrical parts and wiring.
IMPORTANT
■
• Check electrical wiring for damage and loosened
connection every year. To this end, educate the customer to
do his or her own check and at the same time recommend
the dealer to perform periodic check.
• Do not attempt to modify any electrical parts and wiring.
• When removing the battery cables, disconnect the negative
cable first. When installing the battery cables, connect the
positive cable first.
W10111140
[1] WIRING
• Securely tighten wiring terminals.
W10112160
• Do not let wiring contact dangerous part.
W10113130
• Securely insert grommet.

• Securely clamp, being careful not to damage wiring.
W10114580
• Clamp wiring so that there is no twist, unnecessary sag, or
excessive tension, except for movable part, where sag may be
required.
W10115870
• When installing a part, take care not to trap or damage the wiring.
W10116700

[2] BATTERY
• Take care not to confuse positive and negative terminal posts.
• When removing battery cables, disconnect negative cable first.
When installing battery cables, check for polarity and connect
positive cable first.
• Do not install any battery with capacity other than is specified
(Ah).
• After connecting cables to battery terminal posts, apply high
temperature grease to them and securely install terminal covers.
• Do not allow dirt and dust to collect on battery.
CAUTION
• Take care not to let battery liquid spill on your skin and
clothes. If contaminated, wash it off with water immediately.
• Before recharging the battery, remove it from the machine.
• Before recharging, remove cell caps.
• Recharging should take place in a well-ventilated place
where there is no open flame nearby, as hydrogen gas and
oxygen are produced, which is highly flammable. W10118160
[3] FUSE
• Use fuses with specified capacity.
Neither too large or small capacity fuse is acceptable.
• Never use steel or copper wire in place of fuse.
• Do not install working light, radio set, etc. on machine without a
separate power supply.
• Do not install accessories if fuse capacity of reserve power
supply is exceeded.
W10120920
[4] CONNECTOR
• For connector with lock, push lock to separate.
