2 INSTALLATION INSTRUCTIONS WARNING! Make sure the Hopper Safety Support is in place whenever attempting to do any maintenance work under or near the raised hopper. The Hopper Safety Support holds the hopper in the raised position to allow work to be performed under the hopper. NEVER rely on the machine s hydraulic components to safely support the hopper. DISCONNECT BATTERY BEFORE SERVICING. EMPTY HOPPER BEFORE SERVICING. 1 See Figure 1. Remove Knob (A) and Nut (B) from the Left Hand Side Broom Assy (1).

9 18 See Figure 8. Disconnect the existing Hose from the case port of the dust control motor and remove the small connector. 19 Install Tee (7) in place of the original connector and connect Hose (12 / ) from the Valve Assy (4) to the side of the Tee (7) as shown. Reconnect Hose to the end of the Tee (7) as shown. 20 Install Tee (5) between Hose (14 / ) and Hose (13 / ) as shown on page 1 of this instruction sheet. 21 Connect Hose (6 / ) from the side broom assy to the Tee on the bottom of the Valve Assy (4) as shown in Figure 3.

11 27 Completely remove Hose from the machine. NOTE: This hose runs between port E on the hydraulic manifold assy pictured in Figure 9 and the out port on the right side broom motor. 28 Connect Hose (8 / ) coming from the Valve Assy (4) to the out port of the right side broom motor where was previously connected. It should be routed through the Quadruple Clamps on the right side of the hopper where was previously routed as shown in Figure 10. FIGURE 10 RIGHT SIDE OF HOPPER Hose (8) Install Elbow (19) on port E of the hydraulic manifold assy as shown on the fi rst page of this instruction sheet. Connect Hose (10 / ) which was routed through the left side hose sock in step 17 to Elbow (19) as shown. 30 Start the engine. Raise the hopper to the full up position. Pull back on the hopper safety support handle to disengage the hopper safety support, then lower the hopper to the full down position. Shut off the engine Nilfi sk-advance, Inc. (page 11 of 13)

12 31 See Figure 11. Reinstall Knob (A) and Nut (B) removed in step 1. NOTE: Make sure you also reinstall the Fiber Washer (R) and Rubber Washer (S) in the order shown. 32 Install the Side Broom Decal (T) included with the Left Hand Side Broom Assy (1) as shown. 31 Install the Side Broom (U) included with the Left Hand Side Broom Assy (1).

13 32 Test the machine for proper operation by turning on the side brooms while the engine is running at fast idle and the drive pedal is engaged. Both side brooms should turn towards the inside of the machine. Proceed to step 33 to adjust the left side broom height. To adjust the Side Broom Drive the machine to an area with a level fl oor and set the parking brake. 34 Pull the Main Broom Lever back and slide to the right and up to lower the main and side brooms. 35 See Figure 12. When in the Down position, the Left Side Broom (U) should be contacting the fl oor from the 9 O Clock (A1) to the 2 O Clock (A2) area shown. 36 If it requires adjustment, turn the Side Broom Height Adjustment Knob (A) either clockwise to raise or counter-clockwise to lower the side broom. NOTE: You will have to open the hopper cover to access the Adjustment Knob (A). NOTE: The machine should be stored with the Side Brooms in the raised position. The Side Brooms should be replaced when the bristles are worn to a length of 3 inches (7.62 cm) or it becomes ineffective. The Side Broom height must be re-adjusted when ever a broom has been replaced. FIGURE Nilfi sk-advance, Inc. (page 13 of 13)
