Installation 2. Install the push-to-connect air tube connector (21) in place of the needle valve. The agitator speed controller fits the following Graco pneumatic rotary motors: Motor Part No. 101140 16A871 101388 111310 NOTE: Before installing, ensure that the agitator air motor has at least 5 in. (12.7 cm) of vertical clearance and 4 in. (10.2 cm) of horizontal clearance in all directions around it.
. Using the allen wrench (25) and multi-function wrench (26), tighten the compression nut (24) onto the flange connector at least 1/8 turn past finger tight. This provides a firm connection to the motor shaft. 6. Connect the air tubing (27) between the speed controller tube connector (29) and the air motor tube connector (21). TI17258a-1 5. Ensure that the drive shaft hex (C) engages the hex socket (D) in the flange connector.
Operation Connect the main air line to the quick disconnect fitting (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.
Troubleshooting Problem Solution The speed controller does not adjust for a change in load, or shuts off before the knob (16) is turned all the way down. Remove the needle (13). and liberally lubricate the needle and o-ring (33) with multi-purpose lithium based grease. The speed controller does not maintain a consistent speed, or the speed rapidly fluctuates. Replace the needle (13), u-cup (11), and o-ring (33), using Repair Kit 24J886.
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.
