5.9 PRECAUTIONS FOR DISASSEMBLY
1. Since all parts are precisely machined, extreme care
should be taken so the parts may be neither dented
nor scratched by drop and/or contact of such parts.
2. Do not try to hit or wrench when the parts are tightly
fastened. Perform works carefully and patiently, as
hitting or wrenching will cause burrs or damage to
parts, resulting in inability of reassembly, oil leaks
and degradation of performance.
3. Do not leave the parts disassembled. Parts may be
soiled or may be rusted when exposed to damp air
or dusts. When work must be discontinued, provide
an adequate cover to protect the parts from rusts or
dusts.
4. Wash the surface of the motor thoroughly.
5. Drain all hydraulic fluids in piston motor case and oil
passage ports.
6. Select a clean working place to prevent parts from
soil or dusts.
