3. 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.

4. 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 for a fee.
• Do not attempt to modify or remodel 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 be
required.
W10115870
• In installing a part, take care not to get wiring caught by it.
W10116700
• After installing wiring, check protection of terminals and clamped
condition of wiring, only connect battery.

[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
on them.
• 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.
• Do recharging in a well-ventilated place where there is no
open flame nearby, as hydrogen gas and oxygen are formed.
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 which is not
provided with reserve 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.
W10122110
• In separating connectors, do not pull wire harnesses.
• Hold connector bodies to separate.
