1.1 Electric Power
This floor machine operates on a 15 amp nominal
120V, 60 hz, A.C. power circuit. The amp, hertz, and
voltage ratings are listed on the motor spec label found
on each machine. Using voltages above or below those
indicated on the data label will damage the motor.
This floor machine must be grounded while in use to
protect the operator from electrical shock. This floor
machine is equipped with a 3-wire cord and a 3-prong
grounding type plug (Figure 1) to fit the properly
grounded receptacle.
Before using this floor machine, make sure a properly
grounded, 3-hole electrical outlet is available. If not, as
in some older facilities, use an adapter for connecting a
3-prong plug to a 2-prong receptacle (Figure 2).
Check the outlet with a which
quickly indicates if a ground is connected. Correct a faulty
grounding before proceeding.
This floor machine is shipped with a 50 foot (15 M) cord which
plugs directly into an approved outlet. The use of an extension
cord is not recommended.
IMPORTANT!!
IMPORTANT!!
This adaptor be
used in Canada.
Never cut off the
grounding prong for use in a 2-prong
outlet. By doing so, you have cut off your
protection from electrical shock.
Never assume that all 3-hole outlets are properly grounded.

brush block
Unplug the floor machine. Lock the
machine handle in the “up” position
and tip the floor machine back
onto the handle.
Mount the brush or pad driver with
the clutch plate(11) over the
drive plug (12).
Give the brush a quick spin to lock the brush
onto the floor machine.
Now, lower the machine back onto the brush.

This floor machine is shipped from the factory with the handle
unattached. You will need two 7/16” wrenches to complete the
assembly.
Remove the handle and mounting hardware from its carton. Bolts,
nuts, washers and the locking lever assembly are in the plastic bag
attached to the handle.
Align the handle with the yoke (1) over
the mount (2) on the buffer chassis. The
power cord will be facing the motor.
Place a flat washer (4) on a 3” bolt (3),
then place the bolt through the holes in
the yoke and the mount. Place another
washer on the bolt and secure with the
locking nut (5).
Tip the handle up. The handle mounting
collar (7) is designed to slide freely up and
down the handle tube, allowing the handle
to be adjusted for the comfortable
operation of all users. Line up the
mounting collar with the upper holes in the
two bent handle braces (6).
1. Mount the handle on the chassis.
2. Mount the support braces to the
handle.
Place the curved spacer (12) with a
square hole onto the locking lever shaft
(11). The curve must face the lever, as in
the picture at right.
Insert the shaft through the upper hole in
the left handle brace (6), mounting collar
(7), and right handle brace.
Place a spacer (9) on the shaft.
Place the split washer (10) on the shaft
Place the locking wing nut (13) on the shaft.
Tighten and adjust the wing nut. When correctly installed, the

4.0 Troubleshooting
4.1 Floor machine will not run
4.2 Electrical shock to operator
4.3 High Vibration
Check and reset.
Check plug at wall and at machine base.
Plug in.
Test with a working power cord. Lock the
handle up and tip the motor back. Unplug the cord at the motor
and plug the motor into your working power cord.
IMPORTANT! THIS IS JUST FOR TESTING. When you do this, you
have removed the safety handle controls from the circuit and you
are sending power directly to the motor. If the motor now spins,
the problem is in the cord or the handle assembly. Seek
authorized repair service.
If the motor still does not spin, the problem is either in the male
connection at the motor base or in the motor. Seek authorized
repair service.
Seek authorized repair
service.
Seek
authorized service.
Test the outlet with a ground fault
interrupter. Retain a certified electrician to inspect and repair
grounding. NEVER clip off the ground plug on your cord.
High amp draw and circuit breaking can
be an electrical or mechanical problem. Seek authorized repair
service.
Tip machine back and re-center the pad.
