RSL Torque Wrench
Failure to observe and comply with the following
precautions could result in minor or moderate
personal injury. Property damage could also
occur.
• Always carry the wrench by its housing. The
positioning handle is designed only as an aid to
help position the wrench on the bolt or nut.
• Be sure that the backup wrench (on the opposite
end of nut or bolt being tightened or loosened) is
secured so it cannot drop or become disengaged
during bolting procedures.
• Be sure that the hex ratchet size corresponds
to the size of the fastener being loosened or
tightened. Failure to observe this precaution can
result in the wrench becoming unstable and can
lead to catastrophic failure of the tool.
• Always position the wrench for maximum
stability. A positioning handle is avaliable to
properly position tool during operation.
• Be sure reaction points are adequate for the
forces at work during operation of the tool.
• Be sure the reaction point is of a suitable shape.
If possible, 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 arm and
the reaction point. When the tool is operated
the reaction arm and point will make forceful
contact. Be sure the wrench is stable before
applying hydraulic pressure.
• Provide adequate support in vertical and inverted
applications.
• The torque required to loosen a nut is variable
and may exceed the torque capacity of the
wrench. Never operate the wrench at above
75 percent of its rated maximum torque when
loosening a nut or bolt.
• Be sure to minimize torsional and bending
stresses in the wrench, the hex ratchet and any
accessories.
• Bolt lubricants and anti-seize compounds will
have a rated coefficient of friction. Be sure to
know the coefficient of friction for the lubricant
or anti-seize compound that is being used.
To ensure proper tightening of nuts and bolts,
always use this coefficient of friction when
calculating required torque values.
Failure to observe and comply with the following
precautions could result in property damage
and/or void the product warranty.
• Never carry the wrench by its hoses.
• Always use Enerpac pumps and hoses.
• Always use Enerpac replacement parts.
• The maximum torque output of the wrench must
always exceed the torque required to loosen or
tightening the nut or bolt.
• Never operate the wrench with a hydraulic
supply connection to the advance side only as
this may damage the internal parts.
• In severe service conditions, be aware that
the wrench must be inspected, cleaned and
lubricated more frequently than normal (see
Section 5).
• If oil leakage is present from drive unit, replace
seals as required (see section 5) before placing
the drive unit back into service.
• If the wrench is dropped from a significant
height, have the tool inspected and checked
for proper operation before placing it back into
service.
• Always follow the inspection and maintenance
instructions contained in this manual. Perform
maintenance and inspection activities at the
specified time intervals.
