It is recommended that full servicing is carried out on an annual basis by the manufacturer or approved
service agent (other than maintenance, lubrication, and emergency seal replacement). All components
shall be inspected and critical components subjected to nondestructive testing. Hydraulic torque
wrenches will be pressure tested and issued with test certication.
Although it is possible to disassemble the TWHC hydraulic torque wrench on site, it is recommended
that this operation be carried out in a clean workshop environment, as dirt and debris can severely
affect the performance of the seals and other components. Eye protection should be worn at all times
during tool assembly and disassembly.
General servicing/repair can be carried out in three specic areas of the hydraulic torque wrench. This
allows servicing and lubricating of specic components without complete stripdown. The three servicing
areas are:
• Drive components and lubrication.
• Multiswivel manifold components.
• Hydraulic cylinder components.
Full servicing indicates that all three areas are
serviced.
Drive Component Disassembly
The drive components should be lubricated at regular
intervals, typically every three months for normal use
but monthly or even weekly for frequent/prolonged use.
Component lubrication is carried out as follows.
1. Verify the torque wrench is fully retracted. Disconnect
the power supply.
2. See Figure 4. Remove the guard, unscrewing the
guard screws.
