ONNECTIONS
1. Clean all hydraulic couplings before making connections using a clean dry
cloth. Connect hydraulic hoses from rear of foot control valve to hydraulic
motor. See Fig. 4a and 4b. Connect male coupling on the hose to the correspon-
ding female coupling on the foot valve and motor and the female coupling on
the hose to the corresponding male coupling on the foot valve and motor.
2. Clean all hydraulic couplings before
making connections using a clean
dry cloth. Connect foot control valve
to hydraulic power source using fit-
tings on either side of foot control
valve. Hydraulic pressure from power
source to connect to fitting labeled
"INLET PRESSURE" on side of foot
control valve. Connect return line
from power source to fitting labeled
"RETURN TO TANK" on side of foot
control valve. See Fig. 5.
Important – In order for the foot control valve to operate properly it is
important for the flow from the hydraulic power source to the foot control
valve be connected as described in step 2. If the hydraulic flow from the
hydraulic power source to the foot control valve is reversed the valve will not be
able to limit the amount of force on the cable being pulled by the capstan
resulting in possible damage to the cable.
3. Verify all connections then activate hydraulics. Depress foot control valve pedal.
Hydraulic motor shaft should rotate in a clockwise direction when viewed from
the front of the shaft.
