APPLICATION OF POWR-FLITE HEAVY
DUTY 175 RPM
FLOOR MACHINES
(MODELS M201HD-3 and M171HD-3)
The heavy duty standard speed floor machine may be used for
spray buffing, dry buffing, scrubbing and stripping applications.

These heavy duty floor machines are specially recommended for
long term aggressive scrubbing and stripping maintenance. The
M201HD-3 & M171HD-3 heavy duty floor machines are specially
recommended for the following applications:
•Scraping with an attachment tool to remove heavy industrial
deposits and residue or to prepare a foundation for installation of
carpet.
•Wire brushing of concrete floors.
•Sanding with very aggressive sandpaper or sand screen discs.
•Carpet restoration where shampooing & pile lifting require very
stiff brush bristles.
WARNING
To prevent injury, always remove the electrical plug from the
electrical outlet before changing the polishing pad and before
leaving the machine.
PREPARE THE MACHINE FOR
OPERATION
To attach the drive block or brush or other attachment, be sure the
handle is “locked” in the upright position (See picture #1).Lay
the floor machine on its back with the handle lying on the floor,
this exposes the driving plate on the underside of the floor
machine. Holding the drive block, brush or attachment in both
hands and straddling the motor with your back to the handlebox,
bend over and fit the three slots of the clutch plate (build into the
back of the brush) over the three lugs of the driving plate. Turn the
drive block, brush or attachment counter-clockwise as far as it will
go until it is seated in the ready-to-use position. (See picture #2)
CAUTION: This is the only proper way to install a drive block,
brush or attachment. NEVER put a drive block, brush or attach-
ment on the machine by placing it on the floor and moving the run-
ning machine over it, or by placing the machine over the block or
attachment and then starting the motor. Return the floor machine
to upright position and adjust handle to operating position.
Recommended handle position is close to the waist with arms
extended down. Lock the cam release lever into position.
NOTE: The hardened steel cam release lever does not require
extreme tightening to effectively hold the handle in position.
Over-tightening will shorten the functional life of the lever.To
remove drive block, brush or attachment: Lay the floor
machine on it’sback again and disengage clutch plate slots
from driving plate lugs by turning clockwise.
HOW TO OPERATE THE MACHINE
First install the pad driver and pad, brush or other attachments to be
used. Plug the machine in as directed and lower the handle to the
desired operating height and lock in place using the cam lever han-
dle. Push the safety switch forward (see picture #3) and squeeze
the switch triggers beneath the handle grips. This activates the
motor and starts the block, brush or attachment in operation. Each
time you release the triggers the safety switch will reset. You will
need to follow the direction above to restart the machine. CAUTION:
When leaving the machine unattended, disconnect the wall plug
and return the handle to the “locked” upright position to prevent
accidental starting.
TO GUIDE YOUR FLOOR MACHINE
To Right: raise handle slightly. The higher the handle is lifted, the
faster the machine will move to the right. To Left: to change direc-
tion, lower the handle until the machine travels to the left. The
more the handle is lowered, the faster the movement to the left.

TO INSTALL THE OPTIONAL SOLUTION
TANK
Mount the solution tank to the front of the handle and attach with
mounting brackets and knobs. Position the solution tank control
handle horizontally and below the switch lever of the machine and
adjacent to the right handle grip. Remove the plug from the motor
housing and insert the (long) extension tube adaptor and secure at
bottom of machine with the retainer. The solution tank should be
used only with a showerfeed drive block or brush.
APPLICATION OF THE DUAL SPEED
175/320 RPM MACHINES
(MODELS M202-3 and M172-3)
The Powr-Flite dual speed machines will operate in a broad range
of applications. These machines perform all the applications of the
175 RPM standard speed machines and the 300 RPM high speed
machines except the specialized applications.
Do not use dual speed machines for sanding, grinding
or scraping.
The dual speed machines are specially designed for spray cleaning
of heavy traffic areas.
OPERATION OF THE DUAL SPEED
MACHINES
Follow the operation procedures described for 175 RPM
machines.
The proper speed selection is important to properly operate
these machines. Speed selection Low (175 RPM) or High (320
RPM) is made with the switch located on the base and motor
housing.
(See Picture #4)Stripping, scrubbing, bonnet cleaning and
shampooing should be performed at 175 RPM Low Speed. Spray
buffing and dry buffing should be performed at 320 RPM, High
Speed. Spray cleaning is a two speed maintenance operation.
Apply a spray buff chemical to the floor ahead of the machine.
Make the first passes through the spray buff at low speed with an
open weave blue cleaner pad or the brown hoghair blend spray
cleaner pad. Remove the spray cleaning pad and place a buffing
pad on the machine, yellow,beige or natural hoghair blend pads.
Switch the speed to High 320 RPM and buff the dulled finish to a
high gloss. Unplug the power cord and wrap it under the cord
hook and over the right handle grip. Clean the cord off to prevent
heavy soiling and cleaning residues from building up on the
cord. This is a good time to inspect the cord for cuts, gashes and
loose prongs. Tip the machine back and remove the pad and the
drive block or brush. The condition of the floor pad or brush
has a direct affect on the performance of your floor machine.
When the pad becomes dirty,turn it over and use the other side.
When finished, wash the pad or brush and allow it to dry com-
pletely before using it again. Stand the wet brush on the bristles
until dry, then hang up the brush.
Do not store the machine with the drive block, pad or
brush on the machine.
Wipe off the machine housing and wheels to prevent build-up of
unnecessary residue.
TRANSPORTING THE MACHINE
Place the handle in the upright position. Lock the handle cam
release lever. Tip the machine back and transport on the wheels.
MAINTENANCE FOR THE M201-3, ,
M171-3, P131-3, M201HD-3, M171HD-3,
M202-3 and M172-3
Once a month remove the motor cover and vacuum out any dust or
debris which has accumulated on the motor. Replace the motor
cover by setting it over the holes in the housing and replace all of
the screws. Check and maintain the tightness of all the fasteners.
WARNING: Do not over-tighten the switch housing screws.
Keep the machine clean especially at the handle tube and collar
so the handle tube will move freely through the collar. Inspect
the cord for cuts, gashes, or loose prongs; replace as needed.
Disassembly of this motor voids the warranty. Improper
disassembly and assembly of this motor can permanently damage
the field or rotor.
For M202-3 & M172-3 only: The length of the carbon brushes
should be inspected annually. If they are no longer extended
past the holder window, they should be replaced. Replacement
of the carbon brushes should only be done by a qualified
service technician.
