General Information
Operator’s Manual
The Operator’s Manual provides information regarding
the operation, general maintenance and maintenance
intervals for your ProPass machine. Refer to that publi-
cation for additional information when servicing the ma-
chine.
ProPass Hydraulic Supply
Hydraulic supply for the ProPass machine is either
provided by the tow vehicle o r a hydraulic power pack.
If tow vehicle provides hydraulic supply, use tow vehicle
hydraulic specifications for information regarding hy-
draulic flow and relief pressure to the ProPass. If hy-
draulic power pack provides hydraulic supply, see
Chapter 6 -- Hydraulic Power Pack Assembly for inform-
ation regarding hydraulic circuit flow and relief pressure
specifications.
NOTE: See Specifications in this chapter for tow
vehicle hydraulic supply recommendations.
Hydraulic Hose Kit (Tow Vehicle to ProPass)
The hydraulic hose kit used when a ProPass receives its
hydraulic supply from a tow vehicle includes a check
valve in the return hose assembly (item 6 in Figure 1).
If the check valve is removed from the return hose, make
sure that the arrow on the check valve is directed toward
the tow vehicle. Also, when connecting the hydraulic
hoses to the tow vehicle, use the check valve to identify
the return hose for correct installation.
