Manual Extract Precautions :
Precautions for installation work
• Tighten all of the bolts and nuts (sleeve nuts) to the specified torque (KES).
• Install the hoses without twisting or interference and fix them with intermediate clamps, if equipped.
• Replace all of the gaskets, O-rings, cotter pins, and lock plates with new parts.
• Bend the cotter pins and lock plates securely.
• When coating with adhesive, clean and degrease the part, and coat the threaded portion with two to three drops of adhesive.
• When coating with liquid gasket, clean and degrease the surface, and apply it uniformly after making sure that the surface is free from dirt or damage.
• Clean all of the parts, and correct any damage, dents, burrs, or rust found on them.
• Coat the rotating parts and sliding parts with engine oil.
• When press-fitting parts, coat the surface with molybdenum disulfide lubricant (LM-P).
• After installing the snap rings, check that the snap ring is settled in the ring groove completely.
• When connecting wiring connectors, clean the connector to remove all oil, dirt, or water, then connect them securely.
• When using eyebolts, check that there is no deterioration or deformation, screw them in fully, and align the direction of the hook.
• When installing split flanges, fasten them uniformly and alternately to prevent excessive tightening on one side.
a When the cylinders, hydraulic pumps and other hydraulic component are removed for repair, and then reassembled again, be sure to bleed the air as follows before operating the hydraulic cylinders for the first time.
1. Start and run the engine at low idle.
2. Operate the work equipment control lever to operate the hydraulic cylinder and stop at 100 mm off the end of its stroke. Repeat this four to five times.
3. Next, operate the hydraulic cylinder three to four times to the end of its stroke.
