4.6 Tool Operation Instructions [continued]
4.6.14 Reaction and tool leak check:
a.
Check that reaction arm is in firm
contact with stationary object (e.g. nut,
flange, or housing).
b. For new applications:
i. Set pump pressure near zero to start.
ii.
Gradually increase pressure and
carefully watch tool for proper reaction
and oil leaks.
1.
If tool reacts improperly (e.g. Lifts
over reaction point), re-do reaction
setup.
2. If tool leaks, repair leaks immediately.
c. Set pressure to minimum required for
application to maximize tool life.
4.6.15 To tightening a single fastener:
Turn pump off when moving tool.
a. Pressure adjustment:
i. Best practice is to use minimum tool
pressure to extend tool life. Do not
operate at maximum when lower
pressure will work.
ii. For new applications, set pump pressure
near zero to start.
iii. Gradually increase pressure and
carefully watch tool for proper reaction
and oil leaks.
iv. If tool does not react properly (e.g.
Lifts over reaction point), re-do reaction
setup.
b. During this process operator must ensure
reaction arm is in constant contact with
reaction point. This prevents creation of
a pinch point between tool and reaction
point.
i. Follow all applicable safety procedures
with an emphasis on those which
mitigate the pinch point and high
pressure hydraulics hazards.
ii. The operator may determine there are
other precautions which will adequately
minimize the reaction pinch point
hazard.
c. Auto Cycle Pumps - see pump manual
for proper operating instructions.
d. Pump - typical procedure:
i. Depress and hold pendant button until
torque wrench drive makes complete
advance stroke.
ii. Release pendant button to retract
torque wrench drive.
iii. Continue process until tool stalls (pawl
does not engage with another tooth on
square driver or hex insert).
iv. Release pendant button to retract
torque wrench drive.
v. Depress and hold pendant button one
more time to attempt to turn nut.
vi. If nut does not turn, desired torque is
achieved with related stud tension.
