PROBLEM
CAUSE
REMEDY
Low output.
Hyrevz motor speed too slow.
Check power unit for proper flow
(7-9 gprn26-34 Ipm).
Unbalanced or excessive load.
Balance load between circuits.
Load should not exceed rated
capacity.
High backpressure.
Check hydraulic system for
excessive backpressure (over
250 psi/l7 bar).
Couplers or hoses blocked.
Locate and remove restriction.
Oil too hot (above 150°F/660C)
Check hydraulic power source
or too cold (below 50°F/100C).
for proper oil temperature.
Bypass cooler to warm oil or
provide cooler to maintain
proper temperature.
Relief valve set too low.
Adjust relief valve to 2100-2250
psi/145-155 bar.
Hyrevz motor worn.
Inspect and repair or replace.
Output too high.
Hyrevz motor overspeeding.
Check power unit for proper flow
(7-9 gpm/26-34 Ipm).
Hydraulic Motor Generator
Overloaded.
Reduce electrical load. Load
overheats.
should not exceed rated capacity.
