Maintenance And Service - Enerpac HXD Serie Notice D'emploi

IMPORTANT: The torque wrench always
rotates in the direction opposite the rotation
of the cassette. See
12
CAUTION: Do not obstruct the wrench
movement against reaction point. Keep
hands, hoses and swivel connection away
from support arm area.
5.7 Loosening and tightening (continued)
To tighten, operate the pump in the advance
direction by pressing the advance button –
refer to pump instructions. The wrench
performs it angular rotation until it reaches
the end of its rotation cycle. When the
wrench stops, release the advance button to
allow the wrench to automatically retract.
You will know when it have fully retracted as
you will not hear a ratcheting (clicking)
sound. Repeat this operation until the
cassette no longer rotates.
ATTENTION: The cassette 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 (nut) size to
avoid danger of bolt-shearing;
• maximum pressure (torque) for the
various cassettes and reducer inserts to
avoid danger of bolt-shearing and
cassette failure. Maximum torque of
cassettes and reducer inserts are
specified in tables
• maximum pressure 800 bar [11,600 psi].

WARNING:
maximum torque for a bolt (nut)
size will result in bolt shearing
and potential parts failure. These
failures could result in pieces being
projected from the wrench or bolting site.
Failures will also result in the torque wrench
unit moving rapidly away from the torquing
point causing potential injury to the operator.

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

IIMPORTANT: 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 the manufacturer,
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 Enerpac
for repair and/or replacements.
To prolong the life of your torque wrench
equipment, follow points below:
• Do not exceed oil temperature of 65˚C
(150˚F).
• Regularly check the pump's oil level and
condition. Consult pump instructions.
