INSTRUCTIONS
BEFORE
USE
READ CAREFULLY: Most malfunctions in new equipment are the result of improper
operation and/or set-up assembly.
PREPARATION: Remove HYTORC Torque Machine from shipping container.
INSPECTION: Visually inspect all components for shipping damage. If any damage is
found, notify carrier immediately.
2-1
Working Pressure
The tool’s maximum working pressure is 10,000 PSI (700kg/cm2).
Make sure that all hydraulic equipment used with this tool is rated for 10,000 PSI Operating Pressure.
2-2
Hydraulic Connections
With older style pumps (SST-IO, SST-20), the retract side of the system may remain pressurized after the pump has
been switched “off’. This trapped pressure makes it impossible to loosen the retract-side ttings by hand.
To release the pressure, nd the 5/16” manual override holes in the end ofthe black solenoids on the pump. With a
welding rod, allen key or similar device, push in on the ends of both solenoids, each in turn, and the residual pres
sure will be released. All ttings will then be hand tight again.
Newer style pumps (HYTORC 115, HYTORC 230, HYTORC AIR) are equipped with an auto-pressure relief.
Never disconnect or connect any hydraulic hoses or ttings without rst unloading the wrench and the pump. If the
system includes a gauge, double check the gauge to ensure pressure has been released.
When making connections with quick disconnect couplings, make sure the couplings are fully engaged. Threaded
connections such as ttings, gauges, etc., must be clean, securely tightened, and leak free. If tool operates
backwards, couplings are reversed. HYTORC hoses may only be joined together in odd numbers ONLY. If it is
necessary to use 2,4,6 hoses - make an adapter from spare high pressure couplings and nipples.
CAUTION: Loose or improper threaded ttings can be potentially dangerous if pressurized, yet, severe over
tightening can cause premature thread failure. Fittings need only to be securely tightened & leak free. Never
grab, touch or in any way come in contact witb a hydraulic pressure leak. Escaping oil could penetrate the
skin and cause injury.
