SERVICE INSTRUCTIONS

TO CHANGE THE SIDE BROOMS

Change the side brooms when the bristles become worn to less than 3 inches length.

1.Park machine on a smooth level surface, turn key switch to “OFF” position.

2.Place the side brooms lever in the “DOWN” position.

3.Remove the pin that passes through the flange and motor shaft. Remove the broom.

4.Remove the three (3) 1/4 inch bolts and nuts that hold the broom to the motor flange.

5.Assemble the flange to the replacement broom and fasten using the hardware removed in step 4.

6.Install broom to motor shaft with the pin removed in step 3.

7.Check sweep pattern and perform height adjustment so the broom contacts the floor as shown (See Figure 16).

DUST CONTROL SERVICE INSTRUCTIONS

The dust control system consists of the filter baffle and a panel filter. The filter baffle is built in to the hopper and should be checked/cleaned when the hopper is being emptied. The panel filter is located on top of the hopper under the hinged manifold. The panel filter must be replaced if the filter media tears. Inspect the top of the panel for signs of dirt that may be escaping through tears in the filter media.

TO CLEAN THE FILTER BAFFLE

The filter baffle should be cleaned as a first step when the dust control system fails to effectively control dusting while sweeping.

1.Park the sweeper on a smooth level surface, Turn the key switch to the “OFF” position.

2.Open the top cover and disengage the filter manifold latch.

3.Lift the hinged manifold to gain access to the panel filter.

4.Remove the panel filter and inspect for debris lodged in the baffle passages.

5.Dislodge all debris from the baffle manually or with compressed air not to exceed 100 PSI.

6.Install the panel filter. Lower the manifold over the filter and engage the latch.

7.Close the top cover .

TO CLEAN THE PANEL FILTER

Clean the panel filter when the shaker fails to adequately clear the filter pleats.

1.Park the sweeper on a smooth level surface, Turn the key switch to the “OFF” position.

2.Open the top cover and disengage the vacuum manifold latch.

3.Lift the hinged vacuum manifold to gain access to the panel filter.

4.Remove the panel filter and inspect for damage. Replace if not in serviceable condition.

5.Apply compressed air not to exceed 100 PSI to the top side of the panel to backflush lodged dirt from the filter media. The filter may also be cleaned with a solution of soap and water. If this method is used, do not use the panel filter until it has completely dried.

6.Reinstall the cleaned filter and lower the hinged manifold assembly over the filter.

7.Engage the manifold latch and close the top cover.

TO CHANGE THE PANEL FILTER

Change the filter when obvious damage is evident. Inspect for leakage or a heavily loaded filter to the point that cleaning and shaking of the filter has no effect on clearing the pleats.

1.Park the sweeper on a smooth level surface, Turn the key switch to the “OFF” position.

2.Open the top cover and disengage the vacuum manifold latch.

3.Lift the hinged vacuum manifold to gain access to the panel filter.

4.Remove the panel filter and install a new replacement panel.

5.Lower the hinged manifold assembly over the filter.

6.Engage the manifold latch and close the top cover.
