TEST #1
Attach hoses to pump and tool in the normal manner. Press the advance button and hold it down. If the pump pressure
builds and the hoses “flex” but the tool still refuses to cycle, the problem is most likely a loose or defective coupling
connection. To find out where the bad coupling is, remove the tool from the hoses and marry the loose ends together
and cycle the pump. If the gauge pressure reads no more than 500 PSI, then the bad fitting is on the tool. A
significantly greater pressure indicates that the problem is in either the pump or a hose fitting.
TEST #2
Place a welding rod or thin screwdriver in the opening of either side of the solenoid. Press and then release the
advance button. Repeat this process on the opposite side of the solenoid. You should feel the solenoids moving back
and forth. If either side is “dead” the solenoid is bad and needs to be replaced. Note: if in an urgent situation, the tool
may be cycled manually by pushing the solenoids back and forth through these access holes.
TEST #3
Remove tool from hoses. Cycle pump. If pump fails to build pressure, the problem is with the pump. If it does build
pressure, the problem is with hydraulic blow-by in the tool.
TEST #4
Connect tool, pump, and hoses together normally and turn pump “on”. As oil leaks from the small port under the
uni-swivel, use a proper size Allen wrench and slowly tighten (clockwise) the set screw positioned between the
couplings on the uni-swivel. Continue to tighten until the flow stops plus a quarter turn.
TEST #5
THIS TEST SHOULD BE RUN PRIOR TO EVERY USE OF A TORC, LLC. TOOL
Connect the tool, pump, and hoses together as normal. Cycle the pump several times. Cycle the system once more
and observe the sequence of operation. As you depress the advance button, the tool drive should turn about. 24
degrees and you should hear an audible “click”. On square drive tools, you will also notice that the accuracy
assurance levers will move to the rear of the tool and spring forward. At this point, release the advance button. You
should see no further movement and after a moment you will hear another audible “click”. This is how the tools are
designed to operate. If you observe any other sequence of operation, the system is out of order and cannot deliver
more than 10% of its designed capacity, Take immediate corrective action. For reference, tools and pumps are de
signed from the factory plumbed as follows. This ensures that the tool, pump and ONE hose cannot possible be
connected up incorrectly.
Tool
Advance Side - Male
Retract Side - Female
Hose
Advance Side - Female to Female
Retract Side - Male to Male
Pump
Advance Side - Male
Retract Side - Female
Note that connecting two (or any EVEN number) of hoses together creates
“one” hose which is
plumbed backwards! Male to Female and Female to Male. This will cause the system to operate
backwards per Test #5 above. If your hose isn
’t long enough, connect 3 hoses together, move your
pump or call TORC, LLC. for a longer hose assembly.
