TROUBLESHOOTING
The following chart is intended to assist with troubleshooting the HH1358, HV1658, and HV1858 HydraPaks. While not
all inclusive, the chart outlines the most common causes of a problem and the recommended course of action.
The troubleshooting guide for the associated hydraulic tool is in the manual specifically for this equipment.
CAUTION:
IF THE PROBLEM WITH THE ENGINE IS NOT CERTAIN, ALWAYS FOLLOW THE
MANUFACTURER’S WARRANTY POLICY BEFORE ANY OTHER REPAIR OR
MAINTENANCE IS ATTEMPTED.
SYMPTOM
CAUSE AND CORRECTIVE ACTION
HydraPak won’t operate hydraulic tool—
engine operating normally.
Low fluid level in reservoir—fill to required level.
No hydraulic oil pressure caused by:
a.
Flow knob off—if the flow is shut off, there can be no
pressure.
b.
HydraPak pressure relief setting of 2250 psi is too low for
the hydraulic tool being used—check hydraulic tool
requirement.
c.
Air in fluid—inspect for oil leaks and repair to correct.
d.
No work being done—open center tools only produce
pressure under load.
No hydraulic oil flow caused by:
a.
Flow control knob off—turn to ON position and select either
5 or 8 GPM as described in Chapter 3.
b.
Hose disconnected—check hose connections.
c.
Coupling key sheared—inspect and replace.
d.
Damaged pump—inspect and replace.
Flow restriction caused by:
a.
Kinked or damaged hose
b.
Pinched or damage steel line
c.
Poor connection in either a hose or steel line.
Coupling between engine and pump damaged—replace the following
items as required:
a.
Coupling spider worn out
b.
Pump or engine key sheared.
Pump or motor defective—contact the nearest authorized service
center.
HydraPak is operating hydraulic tool slowly or
erratically—engine operating normally.
Hydraulic tool is being overloaded when working on the construction
medium—check hydraulic tool specifications and reduce load on tool
as required.
Low fluid level in reservoir—fill to required level.
