NOTICE
PLEASE READ FIRST BEFORE USING MACHINE
When used properly, your Liberty Shoe Brush Machine is designed to
deliver the most effective and efficient power cleaning of footwear available.
In order to do this, the motorized brushes must spin at a moderate rate of
speed and care must be taken to use the machine correctly.
For maximum performance please note the following:
1 Shoes must be tightly and securely laced and tied. Long hanging
laces can be caught on the brushes as they spin thus causing a problem
for the user of the machine.
2 Nylon stocking, “fashion” shoes, must not be used in the shoe brush
machine. (Examples: open toed shoes, high heels, canvas or sneaker
style footwear and shoes with tassels.)
3 Read this manual before using the Shoe Brush Machine. Important
information for unpacking and handling is included.
4 Unplug unit prior to taking the cover off for replacing any parts.
5 Shoe Brush Machine is intended for indoor use.

MAINTENANCE
To keep the unit looking clean, we recommend the use of a stainless steel
cleaner for maintenance of all exterior and interior parts.
If not maintained properly, the exterior parts may over a period of time
become covered with dirt, grease and grime in such a way that the surface
grime will eventually become unremovable.
Along with a good interior vacuuming, we suggest a thorough weekly
cleaning using a stainless steel cleaner inside and out.
Use a Tacky Mat ® in front of machine to catch small particulate matter
when stepping down or up.
If the above suggestions are followed, your machine will look newer longer
and provide you with years of trouble free service.
REPLACEMENT KIT
Consists of:
1 set of brushes (4)
1 set of belts (3)
1 set of wrenches for socket head screws (4)
