INSTALL HOSES - B-5 (BERT), C-8 (CHARLIE) & D-9 (DANIEL)
Study Fig. 9 very carefully before connecting hoses. Install a 90° street elbow and a 3/4” hose barb in the
suction port on the bottom of the reservoir. Install a 1 1/16 ORB x 3/4” hose barb in the suction port of
the pump and install a 3/4” ID suction hose. Secure the suction hose in place using hose clamps. Install a
1 1/16 ORB x 3/8 NPT adapter and a 3/8 NPT 90° swivel adapter in the `IN’ port of the control valve and
a 7/8 ORB x 3/8 NPT adapter in the pressure port of the pump. Connect a 72” long 3/8” hose between the
pump and the valve.
Install 3/4 ORB male x 3/4 JIC male 90° adapters in the work ports of the control valve and 9/16 ORB
male x 3/4 JIC male straight adapters in the ports on the cylinder. Connect the shorter 3/8” hose with 3/4
JIC fittings from the `B’ port on the control valve to the base end port on the cylinder; connect the longer
3/8” hose with 3/4 JIC fittings from the `A’ port to the rod end port. This will raise the hoist when the con
-
trol lever is pulled back and lower it when pushed forward.
INSTALL HOSES - D-10 (DAVID), E-15 (ERNIE) & F-18 (FLOYD)
Study Fig. 10 very carefully before connecting the hoses. Install a 90° street elbow and a hose barb in the
suction port on the bottom of the reservoir. Install a hose barb in the suction port of the pump and install
the suction hose. Secure the suction hose in place using hose clamps.
Install a 90°swivel adapter in the `IN’ port of the control valve and install a reducing adapter in the pres-
sure port of the pump. Install the 1/2” ID, 72” long hose (3500 psi minimum pressure rating) from the
pump to the valve. Install 7/8 ORB male x 3/4 JIC male 90° adapters in the work ports of the control valve.
Install 3/4 ORB male x 3/4 JIC male straight adapters in the ports on the cylinder.
Connect the shorter 3/8” hose with 3/4 JIC fittings from the base end port of the cylinder to the `B’ port on
the control valve. Connect the longer 3/8” hose with 3/4 JIC fittings from the rod end port of the cylinder
to the `A’ port on the control valve. This will raise the hoist when the control lever is pulled back and lower
it when pushed forward.
NOTE
: The `A’ port is the `power-down’ port and has a pressure of only 500-1000 PSI; the `B’ port has
full system pressure.
