locating plate and the drive unit.

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.
