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 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.
* Important – 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 1: Listed above is the only
hose authorized for use near
electrical conductors.
Hoses 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).

2.5 Hydraulic Fluid Recommendation
Inspect hose for cuts, crushing, leaks,
or abrasion which maybe 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. These fluids are
Recommended by PortaCo inc. Other
That meets or exceeds the specifications
of these fluids may also be used.
