2 Safety

Be aware that the operator is fully
responsible during the operation of
this tool. Enerpac is not responsible for
damage or injury caused by misuse of
this tool. Under some circumstances,
additional safety precautions beyond
those described in this manual may be
required. Contact Enerpac immediately
if a potentially hazardous situation
arises.

Read this manual carefully and
observe all safety precautions.

- Make sure you have completed safety
induction training, specific to the work
surroundings. The operator should be
thoroughly familiar with the controls
and the proper use of the tool.

- The operator must be at least
18 years of age.

- Always wear protective headwear, ear
protectors, footwear and gloves (at a
minimum rigger type gloves) suitable
for safe operation of the tool.
The protective clothing must not
interfere with safe operation of
the tool or restrict the ability to
communicate with co-workers.

- Make sure your workplace is safe.

- Do not place any part of the body
between the reaction foot and the
reaction point.

- Do not place any objects between
the reaction foot and the reaction
point. Keep the hoses away from the
reaction points.

- 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
keep 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 the technical data tables for
maximum pressure setting.

- Make sure that the ratchet size
corresponds to the 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 reaction points
are 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
will become a high velocity projectile.

- Make sure the reaction point is of
a suitable shape. For example use
an adjacent nut or bolt as a reaction
point.

- When the hex ratchet is placed on the
nut or bolt a gap may exist between
the reaction foot and the reaction
plate. When the tool is operated the
reaction foot and point will make
forceful contact. 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. Never operate
the tool at above 75 percent of tool
maximum torque when loosening a
nut or bolt (see section 4.3.2).

- 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 post screws
(see 5.2.1) and gland are tight prior to
use.

- If oil leakage is evident, replace seals
accordingly (see section 5).

- 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 hex
ratchet and any accessories.

- Do not strike the tool with a hammer
while under a full load. This will
invalidate the product warranty.

- Always observe the maintenance
instructions.
