Your new Powr-Flite floor machine will afford you many years of trou-
ble-free operating satisfaction provided it is given proper care. Prior to
packaging, your Powr-Flite floor machine was inspected by a Quality
Control Technician.
UNCRATING
Your Powr-Flite floor machine was protectively packed to prevent
damage in shipment. We suggest that upon removing the unit from its
carton, you carefully inspect it for any possible damage in transit. If
damage is discovered, immediately notify the transportation company
who delivered your machine. As a manufacturer, we are unable to act
upon any claim for concealed damage; you must originate the claim.
IMPORTANT SAFEGUARDS
This machine is designed to be safe when used to perform the
functions specified in this Operator’s Manual. Should damage occur to
electrical or mechanical parts, Prior to further use, the machine
should be repaired by the manufacturer or competent service center
to avoid further damage to the machine or physical injury to user.
Your floor machine is equipped with a safety switch lockout device
designed for your safety.Do not attempt to bypass or defeat the safe-
ty lockout device. Never use any device to lock the power switch trig-
gers in the ON position.

PREPARING THE MACHINE
Toattach the drive block or brush or other attachment, be sure
the handle is “locked” in the upright position. 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
handle box, 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-clock-
wise as far as it will go until it is seated in the ready-to-use posi-
tion. CAUTION: This is the only proper way to install a drive
block, brush or attachment. NEVER put a drive block, brush or
attachment on the machine by placing it on the floor and moving
the running 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 posi-
tion. 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 handle. Push the safety
switch forward and squeeze the
switch triggers beneath the
handle grips. This activates
the motor and starts the block,
brush or attachment in opera-
tion. 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

shown in Sketch A, and is intended for use on a nominal 120 volt
circuit. If a properly grounded receptacle, as shown in Sketch A,
is unavailable, an adapter,as shown in Sketch 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 ground-
ing tap to the faceplate screw.
