SAFETY

ELECTRICAL REQUIREMENTS

WARNING!• Use only manufacturer’s recommended replacement parts, or

equivalent, when servicing this tool.• Do not touch the metal blades on the power cord plug when

removing or installing the plug into an electrical outlet.• To avoid electrical hazards, fire hazards, or damage to the tool,

use proper circuit protection.

Your sander is wired at the factory for 120V operation.Connect to a 120V, 15 Amp time delay fuse or circuitbreaker. To avoid shock or fire, replace power cordimmediately if it is worn, cut or damaged in any way.

Use a separate electrical circuit for your tools. Thiscircuit must not be less than a #12 wire and should beprotected with a 15 Amp time delay fuse. Beforeconnecting the motor to the power line, make sure theswitch is in the OFF position and the electric current israted the same as the current stamped on the motornameplate. Running at a lower voltage will damagethe motor.

Do not modify the power cord plug. If it does notmatch the electrical outlet, have the proper outletinstalled by a qualified electrician.

This tool is intended for use on a circuit that has areceptacle like the oneillustrated: a 3-prongelectrical plug (1) andreceptacle (2) that has agrounding conductor. If aproperly groundedreceptacle is not available,have a certified electriciancheck the receptacle.

WARNING! This sander is for indoor use only. Do notexpose to rain or use in damp location. This tool must begrounded while in use to protect the operator from electricalshock.

Guidelines for Extension CordsUse proper extension cord. Make sure yourextension cord is in good condition. When using anextension cord, be sure to use one heavy enough tocarry the current your product will draw. An undersizedcord will cause a drop in line voltage, resulting in lossof power and cause overheating. The table belowshows the correct size to use depending on cordlength and nameplate ampere rating. If in doubt, usethe next heavier gauge. The smaller the gaugenumber, the heavier the cord.

Use only 3-wire extension cords that have 3-prongplugs and 3-prong outlets that accept the tool’s plug.

Be sure your extension cord is properly wired andin good operating condition. Always replace adamaged extension cord or have it repaired by aqualified person before using it.

Protect your extension cords from sharp objects,excessive heat and damp or wet areas.

Do not modify the plug provided. If it will not fit thereceptacle, have the proper receptacle installed by anelectrician.

In the event of a malfunction or breakdown,grounding provides the path of least resistance forelectric current and reduces the risk of electric shock.This tool is equipped with an electric cord that has anequipment grounding conductor and a grounding plug.The plug MUST be plugged into a matching receptaclethat is properly installed and grounded in accordancewith ALL local codes and ordinances.

Improper connection of the equipment groundingconductor can result in risk of electric shock. Theconductor with the green insulation (with or withoutyellow stripes) is the equipment grounding conductor.If repair or replacement of the electric cord or plug isnecessary, DO NOT connect the equipment groundingconductor to a live terminal.

Check with a qualified electrician or service personnelif you do not completely understand the groundinginstructions, or if you are not sure the tool is properlygrounded.

CAUTION: To avoid personal injury and/or damage to theworkpiece, become familiar with the rotation of the sanding sleeve.

Figure 9

WARNING! Failure to use the correct throat plate with itsmatching sanding sleeve could result in pinched fingers or theworkpiece being pulled down between the throat plate and thesanding sleeve.

Use the throat plate (1) that provides the leastamount of clearance between the sandingsleeve (2) and throat plate opening (3). Thefollowing chart identifies the throat plate opening,sanding sleeve diameter and upper spindlewasher combination.

Sanding Sleeve Selection

WARNING! Do not use this sander for sanding metals.Sanding metals will cause sparks that ignite wood and dustparticles on the sander, in the dust collection system, or in theworkshop.

Selecting the correct grit is extremely important inachieving a high-quality sanded finish. Coarse gritwill remove most material and finer grit willproduce the best finish.

The condition of the workpiece surface to besanded will determine which grit will do the job.

• If the surface is rough, start with a coarse grit.

• Use medium grit to remove scratches left bythe coarser grit.

• Use a finer grit to finish the workpiece.

Sand with each grit until the surface is uniform.Select and install the sanding sleeve for yourparticular application, one that is close in size tothe workpiece that you will be sanding. Install theappropriate throat plate, with the least amount ofclearance for the sanding sleeve you choose.

Note: DO NOT use the sander without a sandingsleeve. Doing so will damage the rubber sanding drum.
