Installation Troubleshooting Tips
Every ERV-750 is factory tested to verify proper operation.
If the ERV-750 is not functioning as expected after you
install it, follow these troubleshooting steps to isolate the
cause.
•
Supply hydraulic power from a separate, properly sized
hydraulic unit (ideally, a Wachs TM7 or similar con-
nected to the auxiliary hose connections).
•
Reconnect to system hydraulic power. If malfunction
continues, diagnose hydraulic system failure. Install cal-
ibrated gauges to verify system pressures and flow.
Return line pressures must not exceed 25 psig. If neces-
sary, route a dedicated return line from the ERV-750 to
the hydraulic reservoir, or increase hose size.
•
Routing a temporary return line to an empty oil drum
will verify brake release with low return line pressure.
