FASTENING SANDER TO A SUPPORTING SURFACE

If the spindle sander has a tendency to tip over, slide, or walk, secure the sander to the supporting surface using the
four holes in the base of the machine. The optional accessory stand has four plastic feet with holes that allow easy
mounting of the stand.

CONNECTING SANDER TO POWER SOURCE

POWER CONNECTIONS

A separate electrical circuit should be used for your tools. This circuit should not be less than #12 wire and should be
protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3-
prong grounding type plugs and 3-hole receptacles which accept the tool’s plug

.

Before connecting the motor to the

power line, make sure the switch is in the “OFF” position and be sure that the electric current is of the same charac-
teristics as indicated on the tool. All line connections should make good contact. Running on low voltage will damage
the motor.

WARNING: DO NOT EXPOSE THE TOOL TO RAIN OR OPERATE THE TOOL IN DAMP LOCATIONS.

MOTOR SPECIFICATIONS

Your sander is wired for 120 volt, 60 Hz alternating current. Before connecting the sander to the power source, make
sure the switch is in the “OFF” position. The 1725 RPM motor provides sixty 7/8" long oscillating strokes per minute.

GROUNDING INSTRUCTIONS

WARNING: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.    

2. 

Grounded, cord-connected tools intended for use

on a supply circuit having a nominal rating less than
150 volts

:

This tool is intended for use on a normal 120-volt circuit
and has a grounded plug that looks like the plug illustrat-
ed in Fig. 15

.

If a properly grounded outlet is not available, a temporary
adapter, shown in Fig. 16, may be used for connecting
the 3-prong grounding type plug to a 2-hole receptacle.
The temporary adapter should be used only until a
properly grounded outlet can be installed by a qualified
electrician. The green colored rigid ear, lug, or the like
extending from the adapter must be connected to a
permanent ground such as a properly grounded outlet
box cover. Whenever the adapter is used, it must be held
in place with a metal screw.

NOTE: In Canada, the use of a temporary adapter is
not permitted by the Canadian Electric Code.

WARNING: IN ALL CASES, MAKE CERTAIN THE 

RECEPTACLE IN QUESTION IS PROPERLY

:  

In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current to
reduce the risk of electric shock. This tool is equipped
with an electric cord having an equipment-grounding
conductor and a grounding plug. The plug must be
plugged into a matching outlet that is properly installed
and grounded in accordance with all local codes and
ordinances.

Do not modify the plug provided - if it will not fit the
outlet, have the proper outlet installed by a qualified
electrician.

Improper connection of the equipment-grounding
conductor can result in risk of electric shock. The
conductor with insulation having an outer surface that is
green with or without yellow stripes is the equipment-
grounding conductor. If repair or replacement of the
electric cord or plug is necessary, do not connect the
equipment-grounding conductor to a live terminal.

Check with a qualified electrician or other service person-
nel if the grounding instructions are not completely and
clearly understood, or if in doubt as to whether the tool
is properly grounded.

Use only 3-wire extension cords that have 3-prong
grounding type plugs and 3-hole receptacles that accept
the tool’s plug, as shown in Fig. 15. Repair or replace
damaged or worn cord immediately.
