It is recommended that you connect the return hoses first and disconnect last to minimize or avoid
trapping pressure within the tool.
When connecting the quick couplers, the flow should run from male coupler to the female coupler. The
female coupler on the tool is the inlet. Quick couplers are marked with a flow direction arrow.
Pressurized fluid escaping from a damaged hose can penetrate the
skin and be injected in the body causing injury or death.
Do not pull on hoses to drag the power unit or tool
.
Note
: When possible, connect the free ends of uncoupled hoses to prevent build up in the hoses. The
sun can also increase pressure in the hoses and make connecting them difficult.
Disconnecting Hoses
1. Stop the hydraulic power source.
2. Rotate the hydraulic circuit control valve in the OFF position.
3. Depressurize the system.
4. Allow system and hydraulic fluid to cool.
5. Disconnect the supply (pressure) hose to the power source (pressure port) from the tool (IN port).
6. Disconnect the return (tank) hose to the hydraulic power source (return port) from the tool (OUT port).
7. To prevent contamination, always install dust caps over the hydraulic ports of the tool when
disconnected.
