Enerpac SQD-Series - Manual (Page 8)

ATTENTION: Socket or Allen-key drive should
not be rotating during retract cycle.
IMPORTANT: After reaching the preset
pressure (torque), the torque wrench will no
longer rotate while the gauge will read the
preset pressure value. Monitor the pressure
gauge on the pump to verify that the bolt/nut
connection has been tightened to the preset
torque values.
If a bolt or nut does not loosen, the torque
(pressure) may be increased. Do not exceed:
• maximum torque for the bolt size to avoid
danger of bolt-shearing;
• maximum pressure (torque) for the Allen-
key drive (hexagon insert) to avoid danger
of bolt-shearing and Allen-key drive failure.
Maximum torque of Allen-key drives are
specified on pages 10-12.
• maximum pressure 800 bar [11,600 psi];
WARNING: Exceeding the maximum
torque for a bolt size or Allen-key
drive will result in bolt-shearing and
potential parts failure. These failures could result
in bolt or Allen-key drive pieces being projected
from the wrench or bolting site. Failure will also
result in the torque wrench unit moving rapidly
away from the torquing point causing potential
injury to the operator.
IMPORTANT: Misuse resulting in
broken or damaged Allen-key
drives, square drives, or internal
components of the wrench, or personal injury,
are not covered under Enerpac's Warranty
policy. Maximum torque of Allen-key drives
are specified in tables
and on pages
10-11.
We recommend the use of special
loosening liquids or sprays.
Enerpac offers nutsplitters in case a
nut can not be removed.
6.0 MAINTENANCE AND SERVICE
IMPORTANT: To safeguard the
accuracy of the torque values, the
torque wrench and pressure gauge
on the pump must be checked on a
regular basis. Contact Enerpac for calibration.
Repairs must be made by Enerpac or an
authorized Service Agent, as after an exchange
of parts, the accuracy of the torque and the
wrench functions must be checked.
Maintenance is required when wear and/or
leakage is noticed. Regularly inspect all
components to detect any problem requiring
service and maintenance. Contact your Enerpac
representative for repair and/or replacements.
To prolong the life of your torque wrench
equipment, follow the points below:
• Do not exceed oil temperature of 150˚F (65˚C).
• Regularly check the pumps’ oil level and
condition. Consult pump instructions.
• Follow the lubrication scheme in section 6.1.
• Lubrication may influence torque accuracy
and life-time of the wrench. Always clean
and lubricate after usage and store in the
carrying case.
6.1 Lubrication
Review illustration . below. Note areas that
are to be cleaned and lubricated on a regular
basis. Follow step 1-4 to re-assemble drive
mechanism after lubrication is completed.
• Clean surface and grease with Gleitmo 805
only. Available at Enerpac as Torque
Wrench Grease EN-14010.
• Keep all other surfaces clean and dry. Do
not lubricate.
IMPORTANT: Do not disassemble the wrench
unit (1) or the drive release (5). Do not immerse
these parts in oil, kerosene or other cleaning
liquid to prevent dirt from flushing in and
grease from being dissolved.
