4.3.2 To loosen a nut or bolt (fig. G)
• Apply releasing oil to the threads.
Allow the oil to soak.
• Position the tool on the nut or bolt
with the anti-clockwise (-) side facing
upwards.
• Operate the pump until the nut or bolt
is loose.
If the nut or bolt will be re-used avoid
excess load when loosening.
- Be aware that when loosening a nut
or bolt more torque is usually required
than when tightening.
- Humidity corrosion (rust) requires up
to twice the torque required for
tightening.
- Sea water and chemical corrosion
requires up to two and a half times
the torque required for tightening.
- Heat corrosion requires up to three
times the torque required for
tightening.
Be aware that when loosening a nut
or bolt shock loading can occur. Do
not apply more than 75% of the
wrench's maximum torque when
loosening nuts or bolts.
