or clamp nut is missing or if the spindle shaft is bent. FREQUENTLY clean grinding dust from beneath grinder. DO NOT OPERATE THIS TOOL WHILE UNDER THE

INFLUENCE OF DRUGS, ALCOHOL, OR ANYMEDICATION.

ALWAYS STAY ALERT. Do not allow familiarity, gainedfrom frequent use of your grinder, to cause a carelessmistake. ALWAYS REMEMBER that a careless fractionof a second is sufficient to inflict severe injury.

STAY ALERT AND EXERCISE CONTROL. Watch whatyou are doing and use common sense. Do not operatetool when you are tired. Do not rush.

SAVE THESE INSTRUCTIONS. Refer to them frequentlyand use them to instruct other users. If you loan someonethis tool, loan them these instructions also.

WARNING:Some dust created by power sanding, sawing, grinding,drilling, and other construction activities containschemicals known to cause cancer, birth defects orother reproductive harm. Some examples of thesechemicals are:

lead from lead-based paints,

crystalline silica from bricks and cement and othermasonry products, and

arsenic and chromium from chemically-treatedlumber.

Your risk from these exposures varies, depending onhow often you do this type of work. To reduce yourexposure to these chemicals: work in a well ventilatedarea, and work with approved safety equipment, suchas those dust masks that are specially designed to filterout microscopic particles.

SAVE THESE INSTRUCTIONS

NEVER reach to pick up a workpiece, a piece of scrap,or anything else that is in or near the grinding path of thewheel.

AVOID AWKWARD OPERATIONS AND HAND POSI-TIONS where a sudden slip could cause your hand tomove into the wheel. ALWAYS make sure you have goodbalance.

NEVER stand or have any part of your body in line withthe path of the wheel.

DO NOT USE TOOL IF SWITCH DOES NOT TURN ITON AND OFF. Have defective switches replaced by anauthorized service center.

BASIC OPERATION

WARNING:Always wear safety goggles or safety glasses with sideshields during power tool operation or when blowing dust.If operation is dusty, wear a dust mask.

To be efficient and work as designed, your tools should

be kept sharp. Dull tools can and will cause accidents.Bench Grinders are ideal for sharpening tools such aschisels, planer blades, scissors, etc., and for removing rustor corrosion.

WARNING:Never sharpen or grind anything made of aluminum.

Grinders remove material rapidly so pressure is the key toefficient grinding.

The proper way to sharpen a tool and avoid overheating is:

Keep the object in constant motion, moving it at an evenpace. Never force a tool against the grinding wheel. Keep the tool cool by using either a cooling tray or a pan

of water. The grinding wheel should rotate into the object being

sharpened.Note : Excessive pressure may damage the tool, cause themotor to overheat, and prematurely wear down the grindingwheel.

WARNING:Excessive pressure on a cold wheel may cause the wheelto crack.

The following recommendations will help you sharpenspecific tools:

TWIST DRILL BITSSee Figure 8.

Drill bits are best sharpened on a sharpening jig (availableat most hardware stores). Begin on one side of the pointat the existing angle, then twist the bit while maintainingcontact with the grinding surface. Sharpen only the tip.

BIT SHARPENING

LAWN MOWER BLADESSee Figure 9 .Lawn mower blades are usually sharpened on only oneedge and dressed up slightly on the other. Perform thissharpening process on both cutting ends of the blade. Aftersharpening, be sure to balance the blade by removingadditional material.

WARNING:Do not attempt to operate this tool until you have readthoroughly and understand completely all instructions,safety rules, etc. contained in this manual. Failure tocomply can result in accidents involving fire, electricshock, or serious personal injury. Save this operator'smanual and review frequently for continuing safeoperation and instructing others who may use this tool.

CAUTION:An unbalanced lawn mower blade may cause excessivevibration which will damage the lawn mower.

This technique requires considerable practice, so take yourtime and make a few dry runs first with the grinder off. Besure to maintain the original cutting edge angle as this isimportant to the efficiency of your bits. One work rest hasa V-groove angled to fit most drill bits.

GENERALKeep the bench grinder clean. Remove dust from workingparts and beneath the grinder frequently.

Make sure the bench grinder operates properly. Checkscrews, nuts, and bolts for tightness.

EXTENSION CORDSThe use of any extension cord will cause some loss of power.To keep the loss to a minimum and to prevent tooloverheating, use an extension cord that is heavy enough tocarry the current the tool will draw.

A wire gage size (A.W.G.) of at least 16 is recommended for

an extension cord 25 feet or less in length. When workingoutdoors, use an extension cord that is suitable for outdooruse. The cord's jacket will be marked WA.

WARNING:Check extension cords before each use. If damaged,replace immediately. Never use tool with a damaged cordsince touching the damaged area could cause electricalshock resulting in serious injury.

WORKLIGHT BULB REPLACEMENTSee Figure 12.

To remove worklight bulb, gently push the bulb into the socketand turn counterclockwise. To install the new bulb, gentlypush the bulb into the socket and turn clockwise.

WHEEL DRESSERDressing a wheel is done to renew sharpness or to true upthe face of the wheel.Set the work rest of the bench grinder at a slight angle andbrace the wheel dresser against it. Do not make contactwith the grinding wheel until after you have turned on themotor and the wheel is rotating at full speed. Press thedresser slightly against the rotating wheel until you get a

bite, then move slowly from side to side across the wheel. Asmall bite and many passes is better than a big bite and onepass. Work cautiously, hold the dresser with force on thework rest. Do not use excessive pressure against thegrinding wheel. Proceed slowly until you master thetechnique.
