4.6 Tool Operation Instructions [continued]
4.6.10 Assemble twin hose to pump (1st) and tool
(2nd) before setting tool on application.
Fig. 4.6-(2/3) and 6.1-1.
a. Always use an odd number (1, 3, 5 …)
of twin hose assemblies to connect tool
to pump.
b. Each end of a twin hose will have one
male and one female quick connect
fitting (QD).
c. Pump will have like male/female fittings.
d. Connect pump high pressure port to
tool high pressure advance port.
e. Connect remaining low pressure ports.
f. Threaded QD assembly procedure (Fig.
4.6-2).
i. Pull female threaded collar back.
ii. Insert male section into female section.
iii. Screw female collar onto male section
until collar solidly contacts male
shoulder.

4.6.11 Purge all air from tool and hoses before
returning to service. Perform a risk
assessment, mitigate hazards, and follow
all appropriate safety procedures during
this process.
a. Purge air from hoses as needed.
i. Connect hoses from pump to each other.
ii. Turn pump on and run for one minute.
b. Purge air from tool as needed.
i. Connect torque wrench drive to pump.
ii. Place torque wrench drive below pump.
iii. Cycle tool until rod extends and retracts
smoothly.
c. Repeat a. and/or b. as needed.
4.6.12 Tighten or loosen fasteners in accordance
with instructions in Section 4.1 to 4.3.
a.
TIGHTENING METHOD 1 - Follow
equipment manufacture's procedures.
b.
TIGHTENING METHOD 2 - Torque
- Legacy Cross-Pattern Tightening
Sequence and Bolt Numbering System
– One Tool
c.
TIGHTENING METHOD 3 – Stud
Elongation
d.
TIGHTENING METHOD 4 – See
Guidelines in Pressure Boundary Bolted
Flange Joint Assembly.
e. LOOSEN (BREAKOUT)
Note: Torque wrench drive, Square Drive
Cassette, Socket and Reaction Arm can be
moved as a unit.
Note: Remember fasteners are typically
tightened, or loosened, incrementally, e.g.
all fasteners are loosened 1/8 turn in a first
pass.
Note: Turn pump off when moving tool.
4.6.13 Determine if fastener will be loosened
or tightened. Set up tool on proper nut
according to the following:
a. Tighten right hand threads: Place tool
on nut so tool advance stroke will
rotate nut clockwise.
b. Loosen right hand threads: Place tool
on nut so tool advance stroke will
rotate nut counter-clockwise.
