MAINTENANCE

DUST FLAPS

The dust flaps are very important to sweeping and dust control and are susceptible to damage and should be inspected daily and maintained in good condition.

CHECKING THE DUST FLAPS

The dust flaps are used on the wheel well, broom chamber and broom door. Inspect the flaps daily and replace any flap that shows signs of wear or deterioration. All flaps should be replaced when worn or damaged to the point that they can no longer perform their normal function. The adjustable flaps have slotted mounting holes to facilitate adjustment.

ADJUSTING THE DUST FLAPS

Adjust the flaps so there is a 1/8" to 1/16" gap between the floor and the bottom edge of the flaps. The rear flapadjustment is 1/16" (16 cm.) above the floor.

1.Park the machine on a smooth level surface and engage the parking brake.

2.Loosen the flap retaining screws and adjust the flap to clear the floor and leave a 1/16" to 1/8" gap.

3.Tighten flap retaining screws while holding flap in position.

4.Drive the machine on a smooth surface and recheck the flaps for proper floor clearance.

FILLING THE HYDRAULIC RESERVOIR (Fig. 94)

 

1.

Access to the hydraulic reservoir is located in the

FILL WITH

 

engine compartment.

HYDRAULIC FLUID

2. Open the hydraulic reservoir breather filter cap.

 

3. Remove any debris that is in the breather filter

 

 

cap screen.

 

4. Fill the reservoir until the fluid is at the “FULL” line on

 

 

the hydraulic fluid sight gauge. The sight gauge is

 

 

located on the center side of the hydraulic reservoir.

 

5. Close the hydraulic reservoir breather filter cap.

 

6. Close the engine compartment cover.

 

CLEANING THE HYDRAULIC SYSTEM

 

1.

Put a drop cloth on the floor.

 

2.

Drive the machine onto the drop cloth.

CHECK FLUID LEVEL

3.

Set the parking brake.

 

4.

Open the hood.

 

 

5.

Put a container under the reservoir drain to catch the

Fig. 94

 

reservoir fluid. Pivot the reservoir out.

 

 

 

 

 

6.Remove the drain plug. The reservoir fluid will drain. Do not use the drained fluid to refill the hydraulic reservoir. Dispose of the used fluid.

7.Flush the interior of the hydraulic reservoir with clean

fluid.

8.Put the reservoir plug, removed in step six, back in the hydraulic tank drain and tighten it. A pipe thread

sealer is required on the plug.

9. Open the breather filter cap.

10.Fill the reservoir with new MOBIL Multipurpose ATF or equilvalent Dextron III. The capacity of the tank is

4.7gal (17.79 liters). Fill to the “FULL” line on the hydraulic fluid sight gauge.

11.Close the breather filter cap.

12.Replace the hood.

REPLACING THE RETURN FILTER ELEMENT (Fig. 95)

1.Replace the return filter element after 250 hours of machine run time.

2.Unscrew the fasteners from the filter assembly cover and retain.

3.Remove the cover and the compression spring and retain.

4.Discard the old filter element.

5.Position the new filter element inside the filter body.

6.Put the compression spring in position. Wipe the cover magnet free of any metal filings or debris.

7.Place O-ring (moisten with clean hydraulic fluid) and cover into position.

8.Reattach fasteners to the filter cover.

9.Clean any hydraulic reservoir fluid spills. The fluid can damage painted surfaces of the machine.
