4 Operation
4.1 Prior to operation
- Make sure the nut or bolt to be
fastened is clean and free of dust.
- Make sure the nut or bolt runs
correctly on the thread.
- Make sure that the threads and the
bearing surface are liberally coated
with the correct lubricant or anti-
seizure compound.
- Make sure that the spanner used to
keep the nut or bolt on the opposite
end in place, is of the correct size
and that there is an adequate
abutment surface. Ensure that the
spanner is secured.
- Contact Enerpac if a suitable
reaction point is not available.
4.2 To set the torque
Adjust the pressure on the pump as
necessary to set the torque.
4.3.1 To tighten a nut or bolt
(fig. G & H)
• Position the tool on the nut or bolt
with the clockwise (+) side facing
upwards.
• Position the reaction foot (17) 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.
Stop operation immediately if a
gap appears between the cylinder
locating plate and the drive unit.
Do not strike the tool with a
hammer while under a full load.
