I PRECOAT BOLTS (Bolts with seal lock agent coating on threads) 1. Do not use the precoat bolt as it is in either of the fol - lowing cases: (a) After it is removed. (b) When the precoat bolt is moved (loosened or tight - ened) by tightness check, etc. 1 Note: For torque check, use the lower limit of the allowable tight - ening torque range. If the bolt moves, retighten it according to the steps below. 2. Method for reuse of precoat bolts (1 ) Wash the bolt and threaded hole. (The threaded hole must be washed even for replacement of the bolt.) (2) Parfectly dry the washed parts by air blowing. (3) Coat the specified seal lock agent to the threaded portion of the bolt.
HIGH PRESSURE HOSE FITTING TIGHTENING TORQUE 1. When connecting a high pressure hose, wipe the hose fitting and mating nipple contact surfaces with clean cloth to remove foreign matters and dirt. Also check no dent or other damage on the contact surfaces before installation. 2. When connecting a high pressure hose, hold the hose to align the fitting with the nipple and tighten the fitting. 3. The maximum tightening torque must not exceed twice the standard tightening torque.
