WARNING

GROUNDING INSTRUCTIONS
LB1500 980101 03/08/03 2-3
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.

The sound pressure level at the operator’s ear was measured to be 70 dBA. This was a nearfield,
broad-band measurement taken in a typical industrial environment on a tile floor. This appliance
contains no possible source of impact noise. The instantaneous sound pressure level is below 63 Pa.

HANDLE INSTALLATION
LB1500 980101 03/08/03 3-2
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 (47331) (attached to handle in a
plastic bag) items 1, 2, and 3.
NOTE: The spacers (items 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.

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.
The handle adjust bar (14344) 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 relationship of
the handle adjust bar nut (57275) or fixed clamp
bolt (70692) and their corresponding nuts
(57275) and washer (87086) have been
disturbed. The handle can be positioned to be
locked with the handle adjust bar pointing either
up or down. In order to change the position the
handle and bolt must be removed and rotated
180 degrees. It is incorrect to make it lock
opposite from the way it was assembled by
applying more force to the nut. From the factory
the locking is in the up position when the
machine handle is locked. The pivot pin (66334)
on the handle adjust bar is off center, in
relationship of the screw to the axis of the (see
drawing). To adjust handle adjust bar, 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.
1. To adjust handle lock, tighten nut on handle while in
the locked position. Optimum locking force and ease
of locking is accomplished when the locking lever
nut is set to a torque of 30 to 50 inch pounds in the
locked position.
2. Gap between clamp halves at the front should be to
the gap in rear when the handle adjust bar is
adjusted properly and in the locked position (gap
approximately 1/16").

breaker to protect the motor in the event an overload
condition occurs. The circuit breaker is located on
the rear of the motor. Push the reset button to restart
the machine. If the breaker trips again, correct the
cause of overloading before proceeding.
DAILY MAINTENANCE
1. Inspect power cord for wear. To prevent
electrical shock replace cords with frayed or
cracked insulation immediately.
