Maximum pressure is ~3,300 psi.
High pressure pump issue.
Replace high pressure pump, see
Unit runs slow.

Check oil level and fill as needed. Perform
Prime TSP Power Pack Procedure
Unit set to 15A setting (120V
only).
Connect to a 20 Amp circuit and set
switch to 20A setting.
Hose connection filter
plugged.
Switch hose connection to other
connectors. Replace filter fitting as
needed.
Hi-flow pump issue.
Replace hi-flow pump, see
High pressure pump issue.
Replace high pressure pump, see
4-way valve issue.
Unit builds full pressure, but torque
wrench fails to advance.
Torque is greater than
wrench capacity at full
pressure.
Use a torque wrench with a larger
capacity.
Advance flow line to wrench
is restricted or blocked.
Check hose couplers for full engagement.
Torque wrench fails to retract.
Return flow from wrench is
restricted or blocked.
Check hose couplers for full engagement.
Pressure indicator does not read
zero (0) psi/bar when pump is
stopped.
Pressure not relieved.
Pressure indicator or gauge
is out of calibration.
Replace pressure transducer or
recalibrate with
TSP power pack does not run at all.

Transducer connection
issue (control board is not
detecting a pressure signal).
1.
Set TSP power pack to OFF and
disconnect power to TSP power
pack.
2.
Check transducer connection.
3.
Disconnect transducer from
connector. Check to see if transducer
contacts are clean and secure.
4.
Reconnect transducer and
connector. Connect power, turn TSP
power pack ON and press Advance
Switch. If TSP power pack does not
run, set TSP power pack to OFF and
proceed to next step.
5.
Connect a confirmed working
transducer to transducer connector.
6.
