ORIGINAL OPERATION MANUAL
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 applications. Longer hoses can be used when necessary, but can
affect the operation of the engine 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.
NOTE
Oil should always flow from the male coupler through the female coupler.
NOTE
The pressure increase in uncoupled hoses left in the sun 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 by PortaCo, Inc. is as follows:
1.
Labeled and certified non-conductive
2.
Wire braided (conductive)
3.
Fabric braided (not certified or labeled non-conductive)
Hose type 1: Listed above is the only hose authorized for use near electrical conductors.
Hose type 2 and 3: Listed above are conductive and must never be used near electrical conductors.
Hose pressure rating
The rated working pressure of the hydraulic hose must be at least 175 bar (2500 psi).
