Precautions when Carrying Out Installation Work 00
• Tighten all bolts and nuts (sleeve nuts) to the specified (KES) torque.
• Install the hoses without twisting or interference and fix them with intermediate clamps, if there are any.
• Replace all gaskets, O-rings, cotter pins, and lock plates with new parts.
• Bend the cotter pins and lock plates securely.
• When coating with adhesive, clean the part and remove all oil and grease, then coat the threaded portion with two to three
drops of adhesive.
• When coating with gasket sealant, clean the surface and remove all oil and grease; check that there is no dirt or damage;
then coat uniformly with gasket sealant.
• Clean all parts, and correct any damage, dents, burrs, or rust.
• Coat rotating parts and sliding parts with engine oil.
• When press-fitting parts, coat the surface with anti-friction compound (LM-P).
• After fitting snap rings, check that the snap ring is fitted securely in the ring groove.
• When connecting wiring connectors, clean the connector to remove all oil, dirt, or water; then connect securely.
• When using eyebolts, check that there is no deformation or deterioration; screw them in fully; and align the direction of
the hook.
• When tightening split flanges, tighten uniformly in turn to prevent excessive tightening on one side.
★ When operating the hydraulic cylinders for the first time after reassembling cylinders, pumps, and other hydraulic
equipment removed for repair, always bleed the air in the following manner:
1. Start the engine and run at low idle.
2. Operate the work equipment control lever to operate the hydraulic cylinder four to five times, stopping the cylinder
100 mm (3.94 in) from the end of its stroke.
3. Next, operate the hydraulic cylinder three to four times to the end of its stroke.
4. After doing this, run the engine at normal speed.
★ When using the machine for the first time after repair or long storage, do the same procedure.
