3. Move the Dust Flap out of the way and
swing open the Broom Arm Assembly.
4. Pull the Main Broom out of the
machine.
To Install the Main Broom
1. Install the Main Broom into the
machine. Rotate the Main Broom as
necessary to make sure the broom
lugs on the far side engage the drive
hub on the broom motor.
2. Close the Broom Arm Assembly,
making sure the Main Broom engages
the Hub on the Broom Arm Assembly.
3. Move the Dust Flap back into position,
then close and latch the Broom Door
4. Check and adjust the broom Arm Stop on the Broom Door as necessary. The Arm Stop should be
adjusted to prevent the Broom Arm from moving outward while still allowing the door to latch easily.
Note:
Make sure you adjust the main broom height when installing a new broom. Failure to do so
will reduce the life of the broom and may lead to setting a code 54 (main broom overload)
which will shut down the main broom.
