Advance and retract operation is controlled
remotely by either electric solenoid valves or
pneumatic solenoid valves.
The advance pressure (A or P) from the pump
to the wrench must be limited to a maximum
800 bar [11,600 psi]. The pressure relief valve at
the retract side (B or T) of the pump must be
set to a maximum 120 bar [1740 psi]. See
tables
, , and on the pages 10-14
for detailed information.
3.0 SAFETY ISSUES
IFailure to comply with the
following cautions and warnings
could cause equipment damage
and personal injury.
IMPORTANT: Minimum age of the
operator must be 18 years. The
operator must have read and
understood all instructions, safety
issues, cautions and warnings before starting
to operate the Enerpac torque wrench. The
operator is responsible for the safety of other
persons in the vicinity of the job.
WARNING: To avoid personal
injury and possible equipment
damage, make sure all hydraulic
components are rated for the
maximum pressure of 800 bar [11,600 psi].
IMPORTANT: Minimize the risk of
overloading. Use hydraulic gauges
in each hydraulic system to indicate
safe operating loads. It is your
window to what is happening in the system.
WARNING: Do not overload
equipment. Overloading causes
equipment failure and possible
personal injury.
CAUTION: Make sure that all
system components are protected
from external sources of damage,
such as excessive heat, flame,
moving machine parts, sharp edges and
corrosive chemicals.
CAUTION: Avoid sharp bends and
kinks that will cause severe back-up
pressure in hoses. Bends and kinks
lead to premature hose failure.
WARNING: Immediately replace
worn or damaged parts with
genuine Enerpac parts. Enerpac
parts are designed to fit properly
and withstand rated loads.
WARNING: Always wear safety
glasses. The operator must take
precaution against injury due to
failure of the tool or workpiece.
DANGER: Do not handle
pressurized hoses. Escaping oil
under pressure can penetrate the
skin, causing serious injury. If oil is
injected under the skin, see a doctor
immediately.
WARNING: Never pressurize
uncoupled couplers. Only use
hydraulic equipment in a coupled
system.
