This unit is compatible with most hydraulically driven sawing and drilling components. The
system may not be compatible with components of some manufacturers.
The power unit was inspected and operated before shipment and should not require any
additional adjustments prior to its initial use.
Hydraulic Fluid: The reservoir of the
hydraulic power unit must be full prior to
start-up. The use of high quality petroleum
based hydraulic oil with the following
properties is recommended:
 Anti-wear
 Low
foaming
 Rust and oxidation inhibitors
 Wide temperature range
 Fluid viscosity: 8-1000 Centistokes
(52-4600 SUS). The unit is shipped
with an ISO 46 Viscosity grade
(8Cs/52SUS @ 212F/100C and
46Cs/210SUS @ 104F/40C).
The oil must be kept free of contamination
to avoid damage to system components.
The strainer in the fill cap must always be
in place when adding oil. Quick
disconnects must be cleaned before
connections are made.
Control Valve: The pressure
compensated flow control valve on this unit
allows full flow control
Flow settings are: 0-2, all flow routed to
tank; 2-10, adjustable range.
Relief pressure can be adjusted by
removing the cap at the top of the main
control and using an Allen wrench to adjust
the relief cartridge. The relief can be set
as low as 750 psi; do not exceed 2400 psi.
To adjust, the flow control must be set at
10 and no tool should be attached. This
will force all flow over relief. Securely
replace the cap as oil seepage will occur
through the relief cartridge. The relief is
factory set and should rarely need
adjustment.
Hydraulic Oil Cooler: The power unit is
equipped with a brazed plate style oil
cooler. Water should be passed through
the cooler before being used for dust
control or blade & bit cooling. Some tools
will automatically shut off water flow when
not actively cutting, drilling, etc. This may
result in higher oil temperatures if the
power unit continues to run without cooling
water.
IMPORTANT: If there is a risk of frost
the water must be drained from the
cooler to prevent damage by freezing.
