INSPECTION
Carefully unpack and inspect your machine for shipping damage. Each unit is tested and
thoroughly inspected before shipment, and any damage is the responsibility of the delivery
carrier who should be notified immediately.
WARNING
• Read Instruction Manual before operating this piece of equipment.
• To reduce the risk of fire use only commercially available floor cleaners and
waxes intended for machine application.
• To reduce the risk of electrical shock, do not expose to rain. Store indoors.
• Do not cross over supply cord, hazard exists when rotating brush passes over cord.
• Electrical motors and components can cause an explosion when operated near volatile
materials and vapors. Do not use this machine near flammable materials such as
solvents, thinners, fuels, grain dust, etc.
ELECTRICAL
(Model MC20003QP) This floor machine is designed to operate on a standard 15 amp.
120 volt, 60 hz, AC circuit. Voltages below 105 volt AC or above 125 volts AC could cause
serious damage to the motor.
(Model MC20004CE) This machine is designed to operate on a standard 16 amp. type L
fused 230 volt, 50 hz, AC circuit. Voltages below 200 volt AC or above 250 volts AC could
cause serious damage to the motor I.E. C. Class 1.
GROUNDING INSTRUCTIONS
• This floor finishing machine should be grounded while in use to protect the operator from
electric shock. The machine is equipped with a three-prong grounding type attachment
plug to fit the proper grounding type receptacle. The green (or green and yellow)
conductor in the cord is the grounding wire. Never connect this wire to other than the
grounding blade.
• If the machine is provided with an attachment plug as shown in Sketch A it is intended
for use on a 120-volt (nominal) circuit. If a properly grounded receptacle as shown in
Sketch A it is intended for use on a 120-volt (nominal) circuit. If a properly grounded
receptacle as shown in Sketch A is not available, an adapter as shown inSketch C is
available and should be installed as shown in Sketch B if the outlet box that houses the
receptacle is grounded. Be sure to fasten the grounding tab with the faceplate screw.
Durability is dependent on floor surface, chemicals used and proper care.

OPERATING INSTRUCTIONS
BEFORE STATING, FAMILIARIZE YOURSELF WITHTHE MACHINE AND ITS CONTROLS
(SEE “MACHINE OVERVIEW” & CONTROL PANEL DIAGRAMS)
1. Filling: Fill the solution tank with the desired amount of water and add liquid
cleaning solution to the proper dilution ratio. DO NOT USE powdered cleaning
chemicals. Powders are unlikely to dissolve thoroughly, resulting in clogging the
in-line solution filter. This can reduce or stop water flow to the brush.
2. Close lid.
3. Turn on machine by pressing the main power switch (10).
4. Lower brush assembly.
-To lower the brush, first push the pedal (7) slightly outward on the machine (unlock it),
and then release it slowly.
-To lift the brush, press the pedal (7) down until lift mechanism engages.
5. Turn on brush (11).
6. Adjust solution control feed lever (4).
7. Turn on vacuum switch (12).
8. Lower squeegee assembly by lowering handle (1).
After Use:
1. Turn off solution feed (4).
2. Switch off brush (11) and raise (7).
3. Raise squeegee assembly (1).
4. Turn off vacuum motor (12).
Solution and recovery tanks should be emptied after every use.
Every 500 hours check condition of carbon brushes on vacuum motor and brush drive motor.

SQUEEGEE ADJUSTMENTS
Squeegee Adjustment
The squeegee set-up is pre-adjusted
at the factory. Adjustments may be required
to get optimum performance for different
floors and conditions.
Pitch Control Adjustment
1. Ensure that the scrubber is on
a relatively flat surface. Pull the
red emergency button away from
the dashboard to activate power.
Turn on the main power switch
and turn the key switch. Raise
the scrubhead off the floor.
Turn the vacuum switch.
2. Lower the squeegee (item 1)
to the floor and move the
machine one or two feet
forward to check the rear
squeegee blade for uniform
deflection to the floor.
3. If uneven deflection or lay is evident, minor adjustments may be necessary to avoid
streaking and uneven wear on the blade.
4. To correct this, pitch adjustment is necessary. Loosen the pivot screw (item 2) and the pitch
screw (item 3). Move the machine forward and allow the squeegee to level itself or adjust
the angular position accordingly to achieve a uniform blade deflection. Re-tighten screws.
5. In certain applications where a different blade set-up is required, the reinforcement blade
(item 4) may be turned upside down. The notch, which is normally on the bottom will now
be located on the topside. This allows the rear squeegee blade a larger deflection than
normal.

BRUSH INSTALLATION - REMOVAL
INSTALLATION
1. Raise the scrubhead to the “UP” position by depressing the pedal (A) downward as
shown on Fig. 1.
2. Center brush (D) under the scrubhead shroud while lining up the center
hex drive hub and pressing the brush up until the brush engages on the drive hub.
REMOVAL
1. Raise the scrubhead to the “UP” position by depressing the pedal (A) downward as
shown on Fig. 1.
2. Remove the brush (D) by stepping on the “BRUSH RELEASE PIN”
on the top of the scrubhead shroud as shown on Fig. 1 below.
