- Do not stand in the line of movement
of the tool when it is in operation. If
the tool separates from the nut or bolt
during operation it will detach in that
direction.
- Tightening and loosening nuts and
bolts involves little visible movement.
The pressure and loads, however
are extreme. Keep your hands away
from the fastener being loosened or
tightened.
- Make sure that the spanner used to
retain the nut or bolt on the opposite
end is secured.
- Always use Enerpac pumps and
hoses.
- Make sure appropriate guards are
always securely in position and free
from damage.
- Maximum pressure is 690 bar (10,000
psi). Never apply more pressure
to any tool or accessory than the
maximum allowable pressure. Refer to
pressure/torque tables for pressure/
torque settings. (see sections 6.3.1
and 6.3.2)
- Make sure that the spanner size
corresponds to the hex size of the
fastener being loosened or tightened.
Failure to do so can result in the tool
becoming unstable and can lead to
catastrophic failure of the tool.
- Do not abuse or overstress the hoses
in any way. Do not bend the hoses
excessively.
- Never carry the tool by its hoses.
- Always use Enerpac spare parts.
- Always position the tool for maximum
stability.
- Make sure the pipe flange is adequate
for the forces at work during
operation of the tool.
- Be aware that a nut or bolt that
breaks off during operation of the tool
may become a high velocity projectile.
- When the spanner is placed on the
nut or bolt a gap may exist between
the reaction roller and the pipe flange.
When the tool is operated the reaction
roller will make forceful contact with
the pipe flange. Always make sure the
tool is stable.
- Provide adequate support in vertical
and inverted applications.
- The maximum torque output of the
tool must always exceed the torque
required to loosen or tighten the nut
or bolt.
- The torque required to loosen a nut is
variable and may exceed the torque
capacity of the tool. Therefore never
operate the tool at maximum or close
to maximum capacity when loosening
a nut or bolt.
- Never operate the tool with a
hydraulic supply connection to
the advance side only as this may
damage the internal parts.
- If the wrench is dropped from a
height, have the tool inspected before
you operate it again.
- In severe conditions the tool must
be cleaned and lubricated more
frequently (see section 5).
- Check that the swivel manifold post
screws (see section 5.3.2) and gland
are tight prior to use.
- If oil leakage is evident, replace seals
accordingly (see section 5.3.2).
- Stop operation immediately if a gap
appears between the cylinder locating
plate and the drive unit. Have the tool
inspected and serviced before you
operate it again.
- Make sure to minimize torsional and
bending stresses in the tool, the
spanner and any accessories.
- Do not strike the tool with a hammer.
This will invalidate the product
warranty.
- Always observe the maintenance
instructions.
