aintenance and care
Check rotating floor brush and drive belt
You should check your vacuum cleaner's
rotating floor brush and drive belt regularly
for wear or damage. You should also clean
the brush and brush ends of strings, hair
and carpet fibers. This type of debris can
wrap around the brush and hamper its
ability to effectively clean your carpet. Also
remove any debris that has accumulated
under the brush cover.
1. Unplug the vacuum from electrical outlet.
2. Place handle in low position and turn
vacuum cleaner over so bottom side is
facing up.
3. Remove the screws marked 1 and 2,
Release the latches marked 3 and 4. Lift
off the brush cover.
4. Grasp rotating floor brush at both ends
and lift.
5. Clean strings, hair and other debris from
rotating floor brush, paying particular
attention to brush ends.
6. Clean strings, hair and other debris from
motor pulley and drive belt areas.
7. Check drive belt carefully for wear, cuts or
stressed areas.
