1.
Sweeper Control.
FORWARD Move the thumb wheel (1) forward in order to rotate the sweeper forward. Use continuous flow control
switch (2) to maintain sweeper rotation.
HOLD The thumb wheel (1) will return when released. The sweeper will stop rotating.
REVERSE Move the thumb wheel (1) backward in order to rotate the sweeper in reverse. Use continuous flow control
switch (2) to maintain sweeper rotation.
2.
Fork Positioning Control.
CLOSE Move the thumb wheel (1) forward in order to reduce fork spacing.
HOLD The thumb wheel (1) will return when released. The left supply line and the right supply line will not be pressur-
ized when the thumb wheel is released.
OPEN Move the thumb wheel (1) backward in order to increase fork spacing.
3.
Continuous Flow Control Switch.
The continuous flow control switch supplies continuous flow of hydraulic fluid to the auxiliary hydraulic circuit (for
rotary sweeper operations) without continuously holding the auxiliary hydraulic control (thumb wheel [1]).
a.
Move thumb wheel (1) for the auxiliary control to the desired flow rate.
b.
Press and hold the continuous flow switch (2).
c.
Release the thumb wheel (1) after you release the continuous flow switch (2). The continuous flow function will
not be activated if the operator does not release the thumb wheel within 1 second of releasing the continuous flow
switch.
d.
Move the thumb wheel (1) or the continuous flow switch (2) in order to stop the flow to the auxiliary hydraulic cir-
cuit.
