WARNING
Wear eye protection .
Always keep guards in pl ace and in p rop er operati ng condition. Do not operate the machine
without the guards for an y reason .
This sander is intended to be used with wood and wood products only. Use of this sander and a
dust collector with metal products is a potential fire hazard.
Support the workpiece adequately at all times during operation; maintain control of the work at all
times.
This sander is designed and intended for use by properly trained and experienced personnel only.
If you are not familiar with the proper and safe operation of a sander, do not use until proper
training and knowledge has been obtained.
• REMOVE ADJUSTING KEYS AND WRENCHES. Form a habit of chec ki ng to see that keys and
adjusting wrenche s are removed from the machine before t ur ning it on.
• KEEP THE WORK AREA CLEAN. Cluttered areas and benches inv ite accident s.
• DON’T USE IN A DANGEROUS ENVIRONMENT. Don’t use power tools in damp or wet loc ations,
or expose them to rain. Keep work area well lighted.
• KEEP CHILDREN AWAY. All visitors should be kept a safe distance from the work area.
• MAKE THE WORKSHOP KIDPROOF with padlocks, m aster swatche s, or by removing starter keys.
• DON’T FORCE THE MACHINE. It will do the job bett er and saf er at t he rate for which it was
designed.
• USE THE RI GHT TOOL. Don’t force a machine or attachment to do a job for which it was not
designed.
• USE THE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When
using an extensi on c or d, be sure to use one heavy enough to carry the current your m ac hine will
draw. An undersized cord will cause a drop in the line voltage resulting in power loss and
overheating. The table following shows the correct size to use depending on the cord length and
nameplate amper e r ating. If in doubt, use the next heavier gauge. Remember , t he smaller the gauge
number, the heavier the cord.

Grounding Instructions
Caution: This tool must be ground ed while in use to protect the operator fro m electric shock.
In the event of a malfunction or breakdown, grounding provi des a path of least resistance for elec tric
current to reduce t he ri sk of elec tric shock. This tool is equipped with an electric cord having an
equipment-gr ounding conductor and a grounding plug. The plug must be plugged into a matching outlet
that is properly installed and grounded in accor danc e wi th all local codes and ordinances.
Do not modify the plug provided. If it will not fit the outlet, hav e the proper outlet installed by a qualified
electrician.
Improper connection of the equipment- gr ounding conductor can result in a risk of electric shock. The
conductor, with insulation having an outer surface that is green with or without yellow stripes, is the
equipment-gr ounding conductor. If repair or replacement of the electric cord or plug i s necessary, do not
connect the equi pm ent- gr ounding conductor to a live t erminal.
Check with a qualified electrician or service per sonnel if t he grounding instructions are not c om pletely
understood, or if i n doubt as to whether t he tool is properly grounded. Use only t hree wire extension
cords that have thr ee- pr ong gr ounding plugs and three-pole r ec eptacles that accept the tool ’s pl ug.
Repair or replace a dam aged or worn cord im mediately.
115 Volt Operation
As received fr om the factory, your sander is ready to run at 115 volt oper ation. This sander, when wired
for 115 volt, is int ended for use on a circuit that has an outlet and a pl ug that look s li k e the one illustrated
in (A). A temporary adapt er , which looks like the adapter as ill ustr ated in (B), may be used to connect
this plug to a two-pole receptacle, as shown in (B) if a properly gr ounded outlet is not available. The
temporary adapt er shoul d only be used until a properly grounded outlet can be installed by a qualified
electrician. This adapter is not applic a ble in Ca nada. The green colored rigid ear, lug, or tab,
extending fr om t he adapter, must be connected to a permanent ground such as a properly grounded
outlet box, as shown in (B ).
