PREPARATION FOR INITIAL USE
The unit as shipped has no special unpacking or
assembly requirements prior to usage. Inspection of
ventilation holes to assure they do not contain packing
debris is all that is required. Otherwise, the unit may be
connected to a hydraulic source upon receipt.
If required, ground bond the electrical load and hydraulic
motor generator at the ground lug mounted on the
alternator frame, lower right (as viewed from the front
SEE PAGE 3).
CHECK HYDRAULIC POWER SOURCE
Using a calibrated flowmeter and pressure
gauge, check that the hydraulic power source develops a
flow of 7-9 gpm/26-34 Ipm at 10002000 psi/70-140 bar.
Make certain the hydraulic power source is
equipped with a relief valve set to open at 2100 psi/145
Wipe all hose couplers with a clean lint-free cloth
before making connections.
Connect the hoses from the hydraulic power
source to the hose couplers on the hydraulic motor
generator. It is a good practice to connect the return
hose first and disconnect it last to minimize or avoid
trapped pressure within the hydraulic motor on the
hydraulic motor generator.
Observe flow indicators stamped on hose
couplers to be sure that oil will flow in the proper
direction. The female coupler is the inlet coupler.
Note: The pressure increase in uncoupled hoses left in
the sun may result in making them difficult to connect.
When possible, connect the free ends of operating hoses
Observe all safety precautions.
Move the hydraulic circuit control on the Pioneer
Tool Outfit (PTO) to the ON position. As the hydraulic
motor generator comes up to speed, a maximum
electrical load of 3500W, single-phase 60-Hz alternating
current, at 120-volts becomes available.
Connect the electrical loads.
Note: Output voltage is proportional to the RPM of the
Before using the hydraulic motor generator in
cold weather, preheat the hydraulic oil at low engine
speed. When using the normally recommended oils, oil
should be at or above 50F/1 0°C (400 ssu/82
centistokes) before use.
