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

AND WIRING
To ensure safety and prevent damage to the machine and
surrounding equipment, heed the following precautions in handling

• 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.
