IMPORTANT
WARNING:
SAFETY INSTRUCTIONS
To reduce the risk of fire, electric shock or injury;
Read all instructions before using this baseboard scrubber.
When using this floor machine, basic precautions should
always be followed,including the following:
1) DO NOT leave the machine plugged in
when not in use. Unplug it from outlet when not in use and/or before servicing.
2) Electric shock could occur if exposed to rain. Store indoors.
3) This is NOT a toy. Close attention is necessary when used around or near chil­dren.
4) Use only as described in this manual. Use only manufacturer's recommended attachments.
5) DO NOT use with damaged cord plug. If the scrubber is not working as it should because it has been dropped, damaged, left outdoors, or dropped into water, con­tact the manufacturer or authorized serv­ice center.
6) DO NOT pull or carry by cord, use power cord as a handle, close a door on cord, or pull cord around sharp edges or corners. DO NOT run the floor machine over the cord. Keep cord away from heat­ed surfaces.
7) DO NOT handle the plug or operate with wet hands.
8) Keep hair, loose clothing, fingers and all parts of body away from moving parts.
9) DO NOT put any object into brushes.
10) DO NOT unplug by pulling on cord. To
unplug, grasp the plug, not the power cord.
11) Use extra care when cleaning on stairs.
12) DO NOT operate where oxygen or anesthetics are used.
13) DO NOT use around flammable or combustible liquids such as gasoline or use in areas where they may be present.
14) DO NOT use an extension cord unless absolutely necessary. If an extension cord is used, then wire size must be #14 gauge or thicker and should not exceed 50 feet in length. Use only a three-wire grounded extension cord to ensure grounding protection.
15) Replace damaged or worn parts immediately with genuine original equip­ment parts to maintain safety and to pro­tect your limited warranty.
This machine must be connected to a properly grounded outlet only. See Grounding Instructions - Page 3.
CARE OF THE SCRUBBER
Treat this baseboard scrubber as you would any other high grade precision made product. Throwing, dropping, unrea­sonable bumping across thresholds and other misuse may result in a damaged unit and invalidate the warranty.

DANGER:
GROUNDING
Improper use of the grounding plug can result in
a risk of electrical shock.
This floor machine must be grounded. If it should malfunction or breakdown, ground­ing provides a path of least resistance for electrical current to reduce the risk of elec­tric shock. This machine is equipped with a cord having an equipment-grounded plug. The plug must be inserted into an appropri­ate outlet that is properly installed and grounded in accordance with all local codes and ordinances
This floor machine is for use on a nominal 120 volt circuit, and has a grounding plug that looks like the plug illustrated in (Fig A). A temporary adaptor that looks like the adaptor illustrated in (Fig B & C) may be used to connect the plug to a 2-pole receptacle as shown in (Fig A) if a proper­ly grounded outlet is not available.
SAFETY
INSTRUCTIONS
If repair or replacement of the cord or plug is necessary, DO NOT connect the grounding wire to either flat blade termi­nal. The wire with insulation having an outer surface that is green with or without yellow stripes is the grounding wire.
GROUNDING
METHODS
The temporary adaptor should be used only until a properly grounded outlet (Fig A) can be installed by a qualified electri­cian. The green color rigid ear, lug, or like extending from the adaptor must be con­nected to a permanent ground such as a properly grounded outlet box cover. Whenever the adaptor is used, it must be held in place by the metal screw (Fig C).
WARNING:
Improper connection of the equipment-grounding conductor can result in a
risk of electrical shock. Check with a qualified electrician or service person if
you are in doubt as to whether the outlet is properly grounded.
DO NOT modify the plug provided with the burnisher. If it will not fit the outlet,
have a proper outlet installed by a qualified electrician.
NOTE: In Canada, the use of a temporary adaptor is not permitted
by the Canadian Electrical Code.
DANGER:
DO NOT leave a plugged-in machine unattended.

PURPOSE OF THIS MACHINE
4" Non-Marking Wheels
The purpose of this machine is to loosen built-up debris in or around baseboards, grout, corners, stairwells, toilet bases and also polishing small floor areas with the optional flex drive.
To effectively clean with this baseboard scrubber:
1) spray an 8 to 10 foot area with a liquid
detergent.
2) Allow the detergent to soak the dirt free while the running the scrubber along the baseboard.
3" Soft Vertical Section
3" Tynex® Vertical Section
4" X 2" Tynex
Horizontal Section
3) Rest the machine on the lower horizon­tal brush, while the vertical brush is scrub­bing the baseboard.
4) Areas that have been neglected over a long period of time many need be be scrubbed more than once.
5) As soon as the dirt is loosened, tank a clean sponge mop and remove the dirt from the floor and baseboard.
6) Rinse the area with clean water to pre­vent a film build-up.

Page 7
The head of the scrubber can be adjusted to the left, right or center. This allows the operator to select a setting more advantageous to his position to clean the area.
OPERATION
To Adjust Scrubber Head:
1) Pull the locking speed pin from the swivel base in front of the handle.
2) Force the head to rotate sideways to the desired position.
3) Replace the speed pin in the alter­nate set of holes and begin cleaning.
This scrubber can be operated on its side with the head set at the center, left or right position. This affords a low sil­houette so the brushes can clean under a shelf or around toilets, plumbing and on stairs.
Cleaning is performed by the combina­tion of the detergent, stripper and motion of the brushes. The wet stripper adds the lubrication to the brush assem­bly. Excessive pressure is not required to clean.
Cleaning
INSTRUCTIONS
Baseboards:
1) Start by spraying the area to be cleaned with a liquid detergent approxi­mately 8 to 10 feet for a baseboard.
2) Allow the cleaning solution to soak the dirt free while the operator runs the scrubber along the baseboard.
3) Rest the scrubber on the lower (Horizontal) brush, while the vertical brush section scrubs the baseboard.
The optional flex drive turns the MWB­90 into a mini-scrubber/buffer with a pad speed of 1075 RPM, accommodat­ing a 6" floor pad. Buff or scrub hard floor surfaces in and around obstruc­tions, elevators and other small areas.
Maintenance:
1) After each use, wipe scrubber with water and a mild detergent solution and rinse using a clean cloth.
2) With baseboard scrubber unplugged, check power cord for any breaks in the wire. Breaks will most likely occur near the plug or switch. Any breaks should be repaired or replaced immediately.
The bottom brush can be replaced by a pad driver. The driver screws on to the threaded brush shaft directly and the cleaning pad is held by barbs on the driver.
Storage:
1) Always storage the machine with the handle in a vertical position.
2) Hang up the the scrubber so not weight is applied to the brush bristles. This will prevent the bristles from flat­tening and warping.
