MAINTENANCE
FIGURE 92
FIGURE 93
HOPPER
The hopper (Fig. 92) houses the debris compartment, the dust control
fi
lter and the removable dust baf
fl
e. For maximum performance and service
life, keep the hopper clean and inspect the seals and
fl
aps daily. Clean the hopper prior to parking the sweeper at the end of the day. A clean
hopper will make inspecting the
fl
aps 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
fi
lter (Fig. 93) should be checked daily for damage and cleaned if necessary. A damaged
fi
lter must be replaced to prevent
damage to other dust control system components. Inspect the
fi
lter for tears in the
fi
lter media or excessive dirt lodged in the pleats. A tear in
the
fi
lter media will allow dirt to pass through the
fi
lter and can be easily seen as a dirty patch on the top side on the
fi
lter. Cleaning of the
fi
lter is
necessary when the
fi
lter 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
fi
lter compartment.
3. Turn
the
fi
lter latch, lift the
fi
lter frame and remove the
fi
lter.
4. Inspect the panel
fi
lter for tears and clean or replace if necessary.
5. Reinstall
the
fi
lter, lower the
fi
lter frame and engage the
fi
lter latch.
6. Close the hopper cover.
CLEANING THE DUST CONTROL FILTER
Clean the dust control
fi
lter when the shaker fails to adequately clear the
fi
lter. The
fi
lter can be cleaned with compressed air not to exceed 100
PSI. To clean the
fi
lter with compressed air, apply the compressed air to the top side of the panel to back
fl
ush the lodged dirt from the
fi
lter pleats.
Be careful to not damage the
fi
lter media while cleaning. The
fi
lter can be cleaned with a solution of soap and water. If this cleaning method is
used do not use the
fi
lter 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
fi
lter compartment.
3. Turn the latch on the hinged frame counterclockwise and lift the frame.
4. Remove
the
fi
lter panel.
5. Install
replacement
fi
lter, lower the hinged frame and engage the latch.
6. Lower
the
fi
lter compartment cover.
