Hose Requirements
It is not often necessary or advisable to use long hoses. All hoses must have an oil resistant inner surface
and an abrasion resistant outer surface. Each hose must have male pipe ends for most application.
Longer hoses can be used when necessary but can affect the operation of the tool due to resistance in
the hose.
If small diameter or long hoses are used, or if restrictive fittings are connected to the supply and return
ports, the pressure required to push the fluid through the system and back to the tank will be higher. This
will reduce tool power.
Important: Oil should always flow from the male coupler through the female coupler.
Note: The pressure increases in uncoupled hoses left in the sun. This may make them difficult to
connect. When possible after use, connect the free ends of the operating hoses together.
Hose Types
Hydraulic hose types authorized for use with the tool are:
1. Labeled and certified non-conductive.
•This is the only hose authorized for use near electrical conductors.
•Constructed of thermoplastic or synthetic rubber inner tube, synthetic fiber braid reinforcement,
and weather resistant thermoplastic or synthetic rubber cover.
2. Wire braided (conductive)
•This hose is conductive and must never be used near electrical conductors.
•Constructed of synthetic rubber inner tube, single or double wire braid reinforcement, and
weather resistant synthetic rubber cover
3. Fiber braided (not certified or labeled non-conductive)
•This hose is conductive and must never be used near electrical conductors.
•Constructed of thermoplastic or synthetic rubber inner tube, synthetic fiber braid reinforcement,
and weather resistant thermoplastic or synthetic rubber cover.
The rated working pressure of the hydraulic hose must be at least 175 bar (2500 psi).

The rated working pressure of the hydraulic hose must be at least 2500 psi / 173 bar.
Hydraulic Fluid Recommendation
Inspect hoses for cuts, crushing, leaks, or abrasion,
which may be a safety hazard or reduce fluid flows.
The following fluids work well over a wide temperature
range at startup, allow moisture to settle out, and resist
biological growth likely in cool operating hydraulic
circuits.
Others that meet or exceeds the specifications of these
fluids may also be used.

Tool Connecting Procedures
1. Stop the engine before connecting the tool and or hoses to the power unit, and when switching hoses
or tools.
2. Turn the hydraulic on/off valve to the off position before starting the engine.
Make sure all hoses are connected for correct flow direction to and from the tool being used.
When routing hose in the work area, position them where personnel will not be at risk of tripping over
them where vehicles can run over the hoses. Do not lay hose over sharp objects.
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.
Connecting Hoses
1. Wipe quick couplers with a clean lint free cloth before connecting them.
2. Depressurize the system.
3. Allow system and hydraulic fluid to cool if too hot to handle.
4. Securely connect the return (tank “R”) hose from the power source to the tool.
5. Securely connect the supply (pressure “P”) hose from the power source to the tool.
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. Depressurize the system.
3. Allow system and hydraulic fluid to cool.
4. Disconnect the supply (pressure) hose to the power source (pressure port) from the tool (IN port).
5. Disconnect the return (tank) hose to the hydraulic power source (return port) from the tool (OUT port).
6. To prevent contamination, always install dust caps over the hydraulic ports of the tool when
disconnected.
