Always use clean gasoline as
recommended in the engine manual. Do
not overfill fluids, clean up oil and fuel
spills immediately.
2.4 Testing
All power units are tested at the factory
and their flows and pressures are
recorded on the test report, which is
shipped with the power unit. Testing of
the power unit is not required unless it is
damaged during shipping.
Always perform “before startup
procedures” found in section 3.3 before
testing. PortaCo Hydraulic Tester, Part
Number T-00016-XX-0 is recommended
for all tests.
a. Set the hydraulic circuit to “OFF.”
b. Connect hydraulic hoses to the
power unit. Connect the PortaCo
Hydraulic Tester to the opposite end
of the hoses. Make sure flow
direction is correct.
c. Start the engine and allow the
hydraulic fluid to warm to about
100° F/38 C°.
d. Open the tester restrictor valve (fully
open.) This represents minimum
load.
e. Set the flow control to “ON” and set
engine throttle for maximum speed.
f. Check the flow rate and pressure on
the tester gauges. The back pressure
reading should be under 17.3 bar
(250 PSI). The flow readings should
match those listed in section 1.1
General Information of this manual.
g. With engine throttle set at maximum
speed slowly close the restrictor
valve on the tester while observing
the flow pressure gauges.
h. As the hydraulic system relief valve
begins to crack (open) and bypass
fluid through the valve, the flow rate
will begin to drop. At this time, the
pressure in the system should be
between 145-155 BAR (2100-2250
PSI).
i. If the pressure is not as specified, the
hydraulic circuit relief valve must be
adjusted or replaced. (See section
4.2 for procedure.)
- If the flow rate drops below the
specified range, the pump or
control valve may be worn.
- If the flow remains constant, but
pressure does not increase, the
relief valve may be defective.
2.5 Adjustments
The engine RPM’s and the hydraulic
system flow and pressure relief are set at
the factory and must not be readjusted.

7
DO NOT change governor setting or
tamper with governor components,
which may increase the governed engine
speed.
WARNING: OPERATING THE
POWER UNIT AT EXCESSIVE
SPEEDS INCREASE THE DANGER
OF PERSONAL INJURY.
2.6 Hose Requirements
The Pioneer series are easily moved
close to the job site. 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.
The pressure and return hose are
connected to the control block. A
½-inch male pipe hose end can be
connected, to H.T.M.A. flat-nosed
quick-disconnect couplings (available
through PortaCo, Inc).
The left port of the control block is the
pressure (oil out) fitting. A male
H.T.M.A. quick-disconnect coupling
(without lock ring) must be connected to
this port.
Two hoses are required to complete the
circuit, each hose should have a male
coupler on one end and a female coupler
on the opposite. See diagram on page 8
for hose routing.
*Important – Oil should always flow
from the male coupler through the
female coupler.
The right port is the return port. A
female H.T.M.A. quick-disconnect
coupling should be connected to this
port.
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. are 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.)

3.0 OPERATING INSTRUCTIONS
3.1 Description of Power Unit
The PortaCo Pioneer series
Hydraulic Power Unit has been designed
for the purpose of supplying hydraulic
fluid under pressure to power hydraulic
hand tools. The standard engine is a
Honda 9 hp, 11 hp, or 13 hp. depending
on the model of power unit purchased.
See section 1.2 features of this manual
for specifications. See the technical
manuals supplied by the engine
manufacture included with this power
unit for detailed technical specifications.
PortaCo Hydraulic Power Units have
been designed for use indoors and
outdoors. PortaCo power units should
not be operated under wet conditions, or
at ambient operating temperatures,
outside the recommended temperature
range of -28° C to 43° C. (-20° F to
110° F).
CAUTION: DO NOT USE CLOSED-
CENTER TOOLS WITH THIS
POWER UNIT.
During operation, the engine may bog,
run at lower rpm, when under load. As
the tool being used is loaded, meets with
increase resistance, the pressure required
to operate the tool increases. The
increased pressure adds load to the pump
which loads the engine, there by
reducing the RPMS. As a result, the
flow will drop as pressure increases.
The hydraulic system has a pressure
limiter set at 148 BAR (2150 PSI) which
diverts the flow back to the tank until the
pressure drops below 148 BAR (2150
PSI.)
Tools with higher flow and, or pressure
requirements will not operate at their full
potential if used with the PortaCo
Hydraulic Power Unit. Tools with lower
flow and or pressure requirements may
be damaged if used with this power unit.
The engine throttle and the hydraulic
system relief value are preset at the
factory and must not be altered for any
reason without consulting PortaCo Inc.
Any alterations approved by PortaCo
Inc., can only be preformed by personnel
qualified to maintain hydraulic systems.
Tools which are commonly used with
PortaCo’s Pioneer series Hydraulic
power unit are as follows:
Impact Wrenches
Impact Drills

1) Observe all safety precautions
2) Rotate hydraulic control valves to
the “OFF” position.
3) Slide the throttle lever to the idle
position.
4) Allow engine to idle for 2 to 3
minutes; then turn ignition “OFF”,
rotate counter clockwise.
5) Disconnect the hoses from the
power unit pressure hose first.
Then disconnect hoses from the
tool. When possible after use,
connect the free ends of the
operating hoses together. The

15
pressure increase in uncoupled
hoses left in the sun may make
them difficult to connect.
6) Allow the hydraulic power unit to
cool down before enclosing in a
small area for transportation or
storage.
B. EMERGENCY SHUTDOWN
In the event of an emergency,
immediately set the ignition switch to
“OFF”.
3.7. Cold Weather Operation
Hydraulic fluids are thicker in cold
weather; therefore, run the engine at low
idle long enough to bring the fluid
temperature up to minimum of 10°C/50°
F or until the hydraulic tank feels warm.
In cold weather, a cover over the cooler
will allow faster warm-up.
3.8 Storage Preparation
To prepare the engine for transportation
or storage refer to the engine owner's
manual. Remove the ground cable from
the battery.
To prepare the hydraulic system for
storage fill the hydraulic oil reservoir to
the full mark, and check that the fill cap
and filter are tight. When removing
from storage during a 3 month or longer
period, drain the water from the
hydraulic oil reservoir, if any
condensation has occurred, and replace
the hydraulic oil filter. (See section 4)
This will remove any water which may
have condensed in the hydraulic oil
reservoir during storage.
Store the PortaCo Pioneer hydraulic
power unit on a smooth level surface.
