GENERAL PRECAUTIONS (1 ) (A) (8) (2) (2) (3) - (4) q 0 CJO (5) 3TMABABOP005A • 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.
