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 flaps
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 FILTER
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 FILTER
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 FILTER
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 FILTER 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.
