if a suitable reaction point is not
available.
4.2 Setting the Torque
Adjust the pressure on the pump as
necessary to set the torque. Refer to pump
manufacturer's instruction manual.
Refer to sections 6.2.1 through 6.2.4 of
this manual for pressure-torque conversion
information.
4.3 Wrench Operation
WARNING
Never strike the tool with
a hammer or other object while it is
under load. Catastrophic failure of the
wrench could occur, and dislodged parts
could become dangerous projectiles.
Uncontrolled release of hydraulic oil
could also occur. Refer to Section 2 of
this manual for additional information.
4.3.1 Tightening a Nut or Bolt
(Fig. 8 and 9)
• If required for your bolting application,
apply lubricant to the bolt threads.
• Install hex socket on the anti-clockwise
(-) side the wrench.
• Install the reaction arm (6) on the
wrench, in the position required for your
application
• Position the tool on the nut or bolt with
the clockwise (+) side facing outwards.
• Position the foot (17) of the reaction arm
(6) against a suitable reaction point (18).
The reaction point will counteract the
force caused by operating the tool.
• Start the pump.
• Operate the pump until the nut or bolt
has been tightened to the required
torque.
• Stop the pump immediately after work
has finished.
