Page 9: Operating The Wrench
2.3 OPERATING THE WRENCH : The position of the Low Profile Hydraulic Torque Wrench relative to the nut determines whether the action will be for Loosening or Tightening of the nut. Refer figure 4 for Low Profile Hydraulic Torque Wrench Position for Tightening and Loosening application. The power stroke of the Piston Assembly will always turn the Ratchet Hex toward the Shroud. -
Page 10: Lubrication
LUBRICATION : The frequency for the lubrication is dependent on operating conditions The Hydraulic Torque Wrench used in a clean enclosed environment will require less servicing than a tool used open atmosphere and dropped in loose dirt or sand. Synthetic Grease is used for lubrication. -
