MAINTENANCE
DUST FLAPS
The dust fl aps 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 fl aps are used on the wheel well, broom chamber and broom door. Inspect the fl aps daily and replace any fl ap that shows signs of
wear or deterioration. All fl aps should be replaced when worn or damaged to the point that they can no longer perform their normal function. The
adjustable fl aps have slotted mounting holes to facilitate adjustment.
ADJUSTING THE DUST FLAPS
Adjust the fl aps so there is a 1/8" to 1/16" gap between the fl oor and the bottom edge of the fl aps. The rear fl ap adjustment is 1/16" (1.6 mm.)
above the fl oor.
1. Park the machine on a smooth level surface and engage the parking brake.
2. Loosen the fl ap retaining screws and adjust the fl ap to clear the fl oor and leave a 1/16" to 1/8" gap.
3. Tighten fl ap retaining screws while holding fl ap in position.
4. Drive the machine on a smooth surface and recheck the fl aps for proper fl oor clearance.
FILLING THE HYDRAULIC RESERVOIR (Fig. 94)
1. Access to the hydraulic reservoir is located in the engine compartment.
2. Open the hydraulic reservoir breather fi lter cap (A).
3. Remove any debris that is in the breather fi lter cap screen.
4. Fill the reservoir until the fl uid is at the "FULL" line on the hydraulic fl uid sight
gauge (B). The sight gauge is located on the center side of the hydraulic
reservoir.
5. Close the hydraulic reservoir breather fi lter cap.
6. Close the engine compartment cover.
CLEANING THE HYDRAULIC SYSTEM
1. Put a drop cloth on the fl oor.
2. Drive the machine onto the drop cloth.
3. Set the parking brake.
4. Open the hood.
5. Put a container under the reservoir drain to catch the reservoir fl uid. Pivot the
reservoir out.
6. Remove the drain plug. The reservoir fl uid will drain.
Do not use the drained fl uid to refi ll the hydraulic reservoir. Dispose of the used
fl uid.
7. Flush the interior of the hydraulic reservoir with clean fl uid.
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 fi lter cap.
10. Fill the reservoir with new MOBIL Multipurpose ATF or equilvalent Dextron III.
The capacity of the tank is 4.7 gal (17.79 liters). Fill to the "FULL" line on the
hydraulic fl uid sight gauge.
11. Close the breather fi lter cap.
12. Replace the hood.
REPLACING THE RETURN FILTER ELEMENT (Fig. 95)
1. Replace the return fi lter element (C) after 250 hours of machine run time.
2. Unscrew the fasteners from the fi lter assembly cover and retain.
3. Remove the cover and the compression spring and retain.
4. Discard the old fi lter element.
5. Position the new fi lter element inside the fi lter body.
6. Put the compression spring in position. Wipe the cover magnet free of any metal fi lings or debris.
7. Place O-ring (moisten with clean hydraulic fl uid) and cover into position.
8. Reattach fasteners to the fi lter cover.
9. Clean any hydraulic reservoir fl uid spills. The fl uid can damage painted surfaces of the machine.
