Troubleshooting Guide continued
Problem
Cause
Solution
Pump delivers excess fluid
pressure.
1. Faulty pressure gauge.
1. Replace gauge.
2. Relief valve set incorrectly.
2. Contact a Power Team Service
Center.
Pump is not delivering
fluid, or delivers only
enough fluid to advance
connected components
partially or erratically or
operation to slow.
1. Fluid level too low.
1. Add fluid, refer to filling the pump
reservoir in Initial Setup section.
2. Loose-fitting coupler to
component.
2. Verify quick-disconnect couplings
to cylinders are completely coupled.
Couplers may need to be replaced
because ball check does not stay open
due to wear.
3. Air in system.
3. Refer to Initial Setup in this
manual to bleed air from system.
4. Air leak in suction line.
4. Check and tighten suction line.
5. Debris in pump or filter plugged.
5. Clean pump filter. If problem
persists, disconnect from power
supply contact authorized Power
Team service center.
6. Fluid bypasses through the
double-acting cylinder.
6. Remove cylinder; cap hoses.
Check pump and valve for leaks.
7. Cold fluid or fluid too heavy.
(Hydraulic fluid is of a higher
viscosity than necessary.)
7. Drain, flush, and refill reservoir
using a lighter weight fluid. Refer to
General Maintenance section.
8. External relief valve or low
pressure unloading valve out of
adjustment.
8. Refer to Adjusting the Pressure
Regulating Valve.
9. Power unit/reservoir capacity
is too small for the size of the
cylinder(s) used.
9. Use smaller cylinder(s) or larger
reservoir.
10. Vacuum in reservoir.
10. Clean plugged vent in filler plug.
Pump builds pressure but
cannot maintain pressure.
1. Fluid leakage.
1. Look for external leaks. If no fluid
leakage is visible, the problem is
internal. If using a double-acting
cylinder, remove it from the system
to ensure the leak is not in the
cylinder. Seal leaking pipe fittings
with pipe sealant.
2. Leaking pressure switch seal.
2. Replace pressure switch.
