Operation

Connect the main air line to the quick disconnect ???tting (28) on the agitator speed controller. Do not exceed the maximum air inlet pressure of 100 psi (0.7 MPa, 7.0 bar).

Set the agitator speed using the knob (16) on the top of the speed controller. Turn the knob counterclockwise (outward) to increase agitator

speed. Turn the knob clockwise (inward) to decrease agitator speed. Once the desired agitator speed is set, the speed controller will maintain that speed by regulating the air???ow to the air motor.

Turn knob counterclockwise to increase speed.

Turn knob clockwise to decrease speed.

To shut off the agitator, disconnect the air supply or turn the speed adjustment knob clockwise until it is fully closed.

Repair

NOTE: To repair the agitator, see your separate agitator manual.

NOTE: Repair Kit 24J886 is available. Order the kit separately. Kit parts are marked with an asterisk, for example (3*). For the best results use all the parts in the kit.

NOTE: Use multi-purpose lithium based grease where ever lubrication is required. Order Part No. 111920.

1.Disconnect the main air line to the speed controller.

2.Disconnect the tube (27) connecting the speed controller and air motor.

3.Unscrew the adjustment nut (15) from the upper housing (2). Turn the knob (16) fully clockwise (inward) to access the o-ring (18) on the bottom plate of the seat (14). Remove the o-ring and replace with the new o-ring (18*). Lubricate the o-ring.

4.Remove the large o-ring (19) on the upper housing (2). Replace with a new o-ring (19*). Lubricate the o-ring.

5.Unscrew the upper housing (2) from the lower housing (1). The drive shaft (4) and cam arms (8) may come out of the lower assembly.

6.Remove the two ball bearing assemblies (3, 20) from the drive shaft (4). Replace with the new ball bearing assemblies. Install the larger ball bearing assembly (3) on the bottom of the shaft. Install the smaller ball bearing assembly (20*) on the top of the shaft, above the large washer (12).

NOTE: The ball bearing assemblies each consist of one bearing and two washers. Place one washer above the bearing and the other washer below the bearing before installing the assembly.

7.Push the needle (13) out of the upper housing

(2) from the top. Using an o-ring pick, remove the u-cup (11) and o-ring (33) from the upper housing. Lubricate the new o-ring (33*) and u-cup (11*) and install in the upper housing. The lips of the u-cup must face up.

8.Lubricate the new needle (13*) and install in the upper housing (2) from the bottom, being sure to align the ???at face on the needle with the mating ???at surface in the housing.

9.Ensure that the cam arms (8) align with the groove on the bottom side of the large washer

(12). Install the drive shaft (4) and cam arm assembly into the lower housing (1), making sure the bearing (3*) seats fully in the recess of the housing.

10.Screw the upper housing (2) fully onto the lower housing (1).

11.Turn the adjustment knob (16) all the way counterclockwise (outward). Screw the adjustment nut (15) fully onto the upper housing
