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.

Improper connection of the 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.

HANDLE INSTALLATION
The machine is shipped with handle unassembled.
Follow these steps for installation:
1. Remove handle and deck assembly from carton. 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.
2. Attach handle assembly to base using hardware kit
(86219680 – PRV NO. 47331) (attached to handle
in plastic bag) items 1, 2 and 3. 4. Check handle for movement up and down.
5. Plug motor cord into handle cord receptacle.
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.

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
individually preset at the factory for optimum
locking efficiency 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.
