Maintenance should follow each period of use to keep the TWHC hydraulic torque wrench in good
working condition.
TWHC Hydraulic Torque Wrench
1. Wipe away any debris that may have accumulated, particularly around the square-drive area, reaction
arm, and hydraulic couplings.
2. Inspect the following components:
• Hydraulic couplings for signs of damage.
• Swivel manifold to verify the retaining ring is present and fitted correctly.
• Verify the guard is present and securely attached. Replace/reattach as necessary.

bearing journals using Revol R5 Moly Anti-Seize, and replace the square drive.

Drive components should be lubricated at regular intervals depending on usage. Refer to the repair
procedures section for instructions.
