Disconnecting Hoses
1.
Stop the power unit.
2.
Disconnect the pressure (supply) hose from the
power unit pressure port to the tool pressure
port (P).
Note: Pressure (supply) hose connection should
always be disconnected before return (tank)
hose connection to prevent pressure build-up
inside the tool.
3.
Disconnect the return (tank) hose from the power
unit return port to the tool return port (T).

To prevent contamination, always install dust caps
over the hydraulic ports of the tool, hoses, and
power unit when disconnected.
IMPORTANT
When new hoses are used, it is necessary to
prefill the hoses to keep the reservoir oil level
from dropping excessively. After connecting new
hoses to the unit, run the unit for a few minutes,
filling the hoses with oil. Stop the unit and check
the oil level of the reservoir. Refill as necessary.
Hydraulic oil should appear in the lower 1/4 of the
sight gauge.
