squeegee. In this position the vacuum remains on to allow vacuuming the water that is left in the squeegee
recovery hose. This prevents water from dripping on the floor with the squeegee raised. If the squeegee is

position. This sytem is designed to bring the machine to a stop in controlled manner. When driving down an

inclined surface, reduce foot pedal pressure rather than releasing the foot throttle. This will provide a controlled

surface, turn key switch to “O” Position and
engage parking brake.

2. Place the side brooms switch in the “UP”
position.

HOPPER

The hopper (Fig. 92) houses the debris compartment, the dust control filter and the removable dust baffle. For
maximum performance and service life, keep the hopper clean and inspect the seals and flaps daily . Clean
the hopper prior to parking the sweeper at the end of the day . A clean hopper will make inspecting the flap s
and seals much easier and will prevent premature deterioration of hopper components. Do not leave the
hopper full of debris while in storage or when parked for extended periods of time. Once the hopper has been
emptied the insides of the hopper should be rinsed out with water.

DUST CONTROL FIL TER

The dust control filter (Fig. 93) should be checked daily for damage and cleaned if necessary . A damaged filter
must be replaced to prevent damage to other dust control system components. Inspect the filter for tears in
the filter media or excessive dirt lodged in the pleats. A tear in the filter media will allow dirt to pass through
the filter and can be easily seen as a dirty patch on the top side on the filter . Cleaning of the filter is
necessary when the filter shaker fails to adequately clean the pleats.

CHECKING THE DUST CONTROL FIL TER

1. Park the machine on a smooth level surface, turn the key switch to the “O” position and engage the
parking brake.

2. Raise the hopper lid for access to the filter compartment.

3. Turn the filter latch, lift the filter frame and remove the filter .

4. Inspect the panel filter for tears and clean or replace if necessary .

5. Reinstall the filter , lower the filter frame and engage the filter latch.

6. Close the hopper cover.

CLEANING THE DUST CONTROL FIL TER

Clean the dust control filter when the shaker fails to adequately clear the filter. The filter can be cleaned with
compressed air not to exceed 100 PSI. To clean the filter with compressed air, apply the compressed air to
the top side of the panel to back flush the lodged dirt from the filter pleats. Be careful to not damage the filter
media while cleaning. The filter can be cleaned with a solution of soap and water . If this cleaning method is
used do not use the filter until it has completely dried.

REPLACING THE DUST CONTROL FIL TER WHEN DAMAGE IS EVIDENT

1. Park the machine on a smooth level surface, turn the key switch to the “O” position and engage the
parking brake.

2. Open the hopper compartment cover to gain access to the filter compartment.

3. Turn the latch on the hinged frame counterclockwise and lift the frame .

4. Remove the filter panel.

5. Install replacement filter , lower the hinged frame and engage the latch.

6. Lower the filter compartment cover .

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 flap s 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
engine compartment.

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 .

FILL WITH

HYDRAULIC FLUID

CLEANING THE HYDRAULIC SYSTEM

1. Put a drop cloth on the floor.

2. Drive the machine onto the drop cloth.

3. Set the parking brake.

CHECK FLUID LEVEL

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.

FILTER

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 A TF or
equilvalent Dextron III. The capacity of the tank is

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

1 1. Close the breather filter cap.

12. Replace the hood.

REPLACING THE RETURN FIL TER ELEMENT (Fig. 95)

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.
