RULES FOR SAFE OPERATION (Continued)

USE RIGHT TOOL. Don'tforce small tool or

attachment to do the job of a heavy duty tool. Don'tuse tool for purpose not intended - for example - A circular saw should never be used for cutting tree limbs or logs.

WEAR PROPER APPAREL. Do not wear loose clothing or jewelry that can get caught in tool's moving parts and cause personal injury. Rubber gloves and nonskid footwear are recommended when working outdoors. Wear protective hair covering to contain long hair and keep it from being drawn into nearby air vents.

ALWAYS WEAR SAFETY GLASSES. Everyday eyeglasses have only impact-resistant lenses; they are not safety glasses.

PROTECT YOUR LUNGS. Wear a face or dust mask if the cutting operation is dusty.

PROTECT YOUR HEARING. Wear hearing protection during extended periods of operation.

DON'TABUSE CORD. Never carry tool by cord or yank it to disconnect from receptacle. Keep cord from heat, oil, and sharp edges.

SECURE WORK. Use clamps or a vise to hold work. It'ssafer than using your hand and it frees both hands to operate tool.

DON'T OVERREACH. Keep proper footing and balance at all times. Do not use on a ladder or

unstable support. Secure tools when working at elevated positions.

MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest performance.

Follow instructions for lubricating and changing accessories.

DISCONNECT TOOLS. When not in use, before servicing, or when changing attachments, blades, bits, cutters, etc., all tools should be disconnected from power supply.

REMOVE ADJUSTING KEYS AND

WRENCHES. Form habit of checking to see that keys and adjusting wrenches are removed from tool before turning it on.

AVOID ACCIDENTAL STARTING. Don'tcarry plugged-in tool with finger on switch. Be sure switch is off when plugging in.

MAKE SURE YOUR EXTENSION CORD IS IN GOOD CONDITION. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. A wire gage size (A.W.G.) of at least 14 is recommended for an

extension cord 50 feet or less in length. A cord exceeding 100 feet is not recommended. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only extension cords suitable for use outdoors. Outdoor approved cords are marked with the suffix W-A, for ex- ample - SJTW-A or SJOW-A.

KEEP BLADES CLEAN AND SHARP. Sharp blades minimize stalling and kickback.

KEEP HANDS AWAY FROM CUTTING AREA. Keep hands away from blades. Do not reach underneath work while blade is rotating. Do not attempt to remove cut material when blade is moving.

WARNING: Blades coast after turn off.

???NEVER USE IN AN EXPLOSIVE ATMO- SPHERE. Normal sparking of the motor could ignite fumes.

INSPECT TOOL CORDS PERIODICALLY and if damaged, have repaired by authorized service facility. Stay constantly aware of cord location and keep it well away from the rotating blade.

INSPECT EXTENSION CORDS PERIODI- CALLY and replace if damaged.

KEEP HANDLES DRY, CLEAN, AND FREE FROM OIL AND GREASE. Always use a clean cloth when cleaning. Never use brake fluids, gasoline, petroleum-based products, or any strong solvents to clean your tool.

STAY ALERT AND EXERCISE CONTROL.

Watch what you are doing and use common

sense. Do not operate tool when you are tired. Do not rush.

CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or re- placed by an authorized service center.

???DO NOT USE TOOL IF SWITCH DOES NOT TURN IT ON AND OFF. Have defective switches

replaced by an authorized service center.

???USE RIP FENCE. Always use a fence or straight edge guide when ripping.

RULES FOR SAFE OPERATION (Continued)

SUPPORT LARGE PANELS. To minimize the risk of blade pinching and kickback, always support large panels as shown in Figure 9, page 10. When cutting operation requires the resting of the saw on the workpiece, the saw should be

rested on the larger portion and the smaller piece cut off.

???LOWER BLADE GUARD.

_k WARNING: If lower blade guard must be raised to make a cut, always raise it with the retracting handle to avoid serious injury. See Figure 20,

Page 15.

???GUARD AGAINST KICKBACK. Kickback occurs when the saw stalls rapidly and is driven back towards the operator. Release switch immedi- ately if blade binds or saw stalls. Don'tremove saw from work during a cut while the blade is moving. See Pages 9 and 10.

???BEFORE MAKING A CUT, BE SURE THE

DEPTH AND BEVEL ADJUSTMENTS ARE

TIGHT.

USE ONLY CORRECT BLADES. Do not use blades with incorrect size holes. Never use blade washers or bolts that are defective or incorrect.

The maximum blade capacity of your saw is 7-1/4 inches.

AVOID CUTTING NAILS. Inspect for and remove all nails from lumber before cutting.

NEVER touch the blade or other moving parts during use.

NEVER start a tool when its rotating component is in contact with the workpiece.

NEVER lay a tool down before its moving parts have come to a complete stop.

DO NOT operate this tool while under the influence of drugs, alcohol, or any medication. POLARIZED PLUGS. To reduce the risk of electric shock, this tool has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.

WHEN SERVICING USE ONLY IDENTICAL

CRAFTSMAN REPLACEMENT PARTS.

SAW BLADES

The best of saw blades will not cut efficiently if they are not kept clean, sharp, and properly set. Using a dull blade will place a heavy load on your saw and increase the danger of kickback. Keep extra blades on hand, so that sharp blades are always available.

Gum and wood pitch hardened on blades will slow your saw down. Use gum and pitch remover, hot water, or kerosene to remove these accumulations.

Do not use gasoline.

BLADE GUARD SYSTEM

The lower blade guard attached to your circular saw Is there for your protection and safety. It should never be altered for any reason. If it becomes damaged or begins to return slow or sluggish, do not operate your saw until the damage has been repaired or replaced. Always leave guard in operating position when using saw.

_k DANGER: When sawing through workpiece, lower blade guard does not cover blade on the

underside of workpiece. Since blade is exposed on underside of workpiece, keep hands and fingers away from cutting area. Any part of your body coming in contact with moving blade will result in serious injury. See Figure 5.

LOWERBLADEGUARD

IS iN UP POSITION

WHENMAKINGA CUT

KICKBACK

See Figure 6.

The best guard against kickback is to avoid dangerous practices.

Kickback occurs when the blade stalls rapidly and the saw is driven back towards you. Blade stalling is caused by any action which pinches the blade in the wood.

KICKBACK IS CAUSED BY:

???Incorrect blade depth setting. See Figure 6.

???Sawing into knots or nails in workpiece.

???Twisting blade while making a cut.

???Making a cut with a dull, gummed up, or impropedy set blade.

???Incorrectly supporting workpiece. See Figure 7.

???Forcing a cut.

CAUTION: Never use saw when guard is not operating correctly. Guard should be checked for correct operation before each use. If you drop your saw, check the lower blade guard and bumper for damage at all depth settings before reuse. Note: The guard is operating correctly when it moves freely and readily returns to the closed position. If for any reason your lower blade guard does not close freely, take it to the nearest Sears Repair Center for service before using.

???Cutting warped or wet lumber.

???Tool misuse or incorrect operating procedures.

9

TO LESSENTHECHANCEOFKICKBACK:

???Always keep the correct blade depth setting - the correct blade depth setting for all cuts should not exceed 1/4 inch below the material to be cut. See Figure 8.

???Inspect the workpiece for knots or nails before beginning a cut. Never saw into a knot or nail.

???Make straight cuts. Always use a straight edge

guide when rip cutting. This helps prevent twisting the blade in the cut.

???Always use clean, sharp and properly set blades. Never make cuts with dull blades.

???To avoid pinching the blade, support the workpiece properly before beginning a cut. The right and wrong ways to support large pieces of work are shown in Figures 7 and 9.

???When making a cut use steady, even pressure. Never force cuts.

???Do not cut warped or wet lumber.

???Always hold your saw firmly with both hands and keep your body in a balanced position so as to resist the forces of kickback should it occur.

When using your saw, always stay alert and exercise control. Do not remove your saw from workpiece while the blade is moving.

DEPTH OF CUT ADJUSTMENT

Always keep correct blade depth setting. The correct blade depth setting for all cuts should not exceed 1/4 inch below the material to be cut. More blade depth will increase the chance of kickback and cause the cut to be rough.

TO ADJUST BLADE DEPTH

???Unplug your saw.

_ WARNING: Failure to unplug your saw could result in accidental starting causing possible

serious personal injury.

???Loosen wing nut. See Figure 10.

???Hold base flat against the workpiece and raise or lower saw until the required depth is reached.

???Tighten wing nut securely.

10

STARTING A CUT

Know the right way to use your saw.

See Figure 11.

TO HELP MAINTAIN CONTROL:

???Always support your workpiece near the cut.

???Support your workpiece so the cut will be on your right.

???Clamp your workpiece so it will not move during the cut.

Place your workpiece with its good side down. Note: The good side is the side on which appearance is

important.

Before beginning a cut, draw a guideline along the desired line of cut. Then place front edge of base on that part of your workplace that is solidly supported.

See Figure 11.

Never place your saw on that part of the workplece that will fall off when the cut is made.

See Figure 13.

_, WARNING: To make sawing easier and safer, always maintain proper control of your saw. Loss of control of your saw could cause an accident resulting in possible serious injury.

Never use your saw as shown in Figure 12.

Never place your hand on the workpiece behind your saw while making a cut.

Keep the cord away from cutting area. Always place the cord to prevent it from hanging up on the workpiece while making a cut.

,_ DANGER: If the cord hangs up on the workpiece during a cut, release the switch trigger

immediately. Unplug your saw and reposition the cord to prevent it from hanging up again,

,_ DANGER: Using your saw with a damaged cord could result in serious injury or death. If the cord

has been damaged, have it replaced before using your saw again.

11

Hold your saw firmly with both hands.

See Figure 14.

CAUTION: When lifting your saw from the workpiece, the blade is exposed on the

underside of your saw until the lower blade guard closes. Make sure lower guard is closed before setting your saw down on work surface.

TO CROSS CUT OR RIP CUT

When making a cross cut or rip cut, align your line of cut with the outer blade guide notch on the saw base as shown in Figure 15.

,_ WARNING: The blade coming in contact with the workpieca before it reaches full speed could

cause your saw to "kickback" towards you resulting in serious injury.

When making a cut use steady, even pressure. Forcing causes rough cuts, could shorten the life of your saw and could cause "kickback."

REMEMBER:

When sawing through work, the lower blade guard does not cover the blade, exposing it on the underside of work. Keep your hands and fingers away from cutting area. Any part of your body coming In contact with the moving blade will result In serious Injury.

After you complete your cut release the trigger and allow the blade to come to a complete stop. Do not remove your saw from workplece while the blade Is moving,

Since blade thicknesses vary, always make a trial cut in scrap material along a guideline to determine how much, if any, the guideline must be offset to produce an accurate cut. Note: The distance from the line of cut to the guideline is the amount you should offset the guideline,

12

TO BEVEL CUT

The angle of cut of your saw may be adjusted to any desired setting between zero and 51.5 ??. Note: When making cuts at 51.5 ?? blade should be set at full depth of cut, with edge guide screw removed.

When making 45 ?? bevel cuts, there is a notch in the saw base to help you line up the blade with the line of cut. See Figure 16.

BEVEL

SCALE

Align your line of cut with the inner blade guide notch on the saw base when making 45 ?? bevel cuts.

Since blade thicknesses vary and different angles require different settings, always make a trial cut in scrap material along a guideline to determine

how much you should offset the guideline on the board to be cut.

When making a bevel cut hold your saw firmly with both hands as shown in Figure 17.

Rest the front edge of the base on the workpiece.

Squeeze the switch trigger to start your saw. Always let the blade reach full speed, then guide your saw into the workpiece.
