Grounding Instructions - 120v
THIS PRODUCT IS FOR COMMERCIAL
USE ONLY.
Electrical:
In the USA this machine operates on a 15 amp
nominal 120V, 60 hz, A.C. power circuit. The amp,
hertz, and voltage are listed on the data label found
on each machine. Using voltages above or below
those indicated on the data label will cause serious
damage to the motors.
Grounding Instructions:
This appliance must be grounded. If it should
malfunction or break down, grounding provides a
path of least resistance for electric current to reduce
the risk of electric shock. This appliance is equipped
with a cord having an equipment-grounding
conductor and grounding 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 appliance is for use on a nominal 120-volt circuit,
and has a grounded plug that looks like the plug in
“Fig. A”. A temporary adaptor that looks like the
adaptor in “Fig . C” may be used to connect this plug
to a 2-pole receptacle as shown in “Fig. B”, if a
properly grounded outlet is not available. The
temporary adaptor should be used only until a
properly grounded outlet (Fig. A) can be installed by
a qualified electrician. The green colored rigid ear,
lug, or the 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 a metal screw.
Improperconnection ofthe equipment-grounding
conductor can result in a risk of electric 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 appliance - if it will not fit the
outlet, have a proper outlet installed by a
qualified electrician.
Le raccordement incorrect du conducteur de
terre d'équipement peut entraîner des risques
d'électrocution. Vérifiez auprès d'un électricien
qualifié ou d'un responsable de l'entretien si
vous avez quelque doute que ce soit quant au
raccordement à la terre de votre prise murale. Ne
modifiez pas la fiche fournie avec l'appareil: si
elle ne correspond pas à la prise murale, faites
installer une prise adéquate par un électricien
qualifié.

Grounding Instructions - 230v
THIS PRODUCT IS FOR COMMERCIAL USE
ONLY.
Electrical:
The amp, hertz, and voltage are listed on the data
label found on each machine. Using voltages above
or below those indicated on the data label will cause
serious damage to the motors.
Extension Cords:
If an extension cord is used, the wire size must be at
least one size larger than the power cord on the
machine, and must be limited to 50 feet (15.5m) in
length.
Grounding Instructions:
This appliance must be grounded. If it should
malfunction or break down, grounding provides a
path of least resistance for electric current to reduce
the risk of electric shock. This appliance is equipped
with a cord having an equipment-grounding
conductor and grounding plug. The plug must be
inserted into an appropriate outlet that is properly

The machine is shipped with handle unassembled.
Follow these steps for installation:
1. Remove handle and deck assembly from carton.
2. Attach handle assembly to base using hardware
kit (86219680 – PRV NO. 47331) (attached to
handle in plastic bag) items 1, 2 and
NOTE: The spacers (item 1) are required for the
correct operation of the handle. The spacers are
positioned completely inside the pivot holes in the
casting, and are held in place by tightening the
bolts and washers (items 2 and 3 against the
spacer.
3. Remove bolt, nut and washers (items 4, 5 and 6)
from lower block on handle assembly. Attach
links as shown. Tighten bolt and nut securely,
then back off 1/4 to 1/2 turn.
4. Check handle for movement up and down.
5. Plug motor cord into handle cord receptacle.

Operations
Controls
1. Safety Lock – Prevents unintended operation of
the machine.
2. Switch Levers – Turns machine on/off.
3. Adjustment Handle – Allows the handle to be
adjusted to a comfortable operating position.
Handle Height Adjustment
NOTE: The handle is in the up, locked position
from the factory.
The handle adjust bar (1) for the polishers are individ-
ually preset at the factory for optimum locking effi-
ciency and minimum effort of engaging. It should not
be necessary to adjust the handle adjust bar unless
the handle adjustment bar (1) the washer (3) and nut
(2) have been disturbed.
NOTE: It is incorrect to make it lock opposite
from the way it was assembled by applying
more force to the nut.
The pivot pin is off center in relationship to the axis of
the handle. To adjust handle, tighten nut on handle
while in the locked position. The handle is locked
when the screw is to the outside of the machine and
the flat on the opposite side of the handle is flush to
the bracket.
