2.KEEP GUARDS IN PLACE and in working order.

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

4.KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.

5.DO NOT USE IN DANGEROUS ENVIRONMENT. Do not use power tools in damp or wet locations, or expose them to rain. Keep work area well lighted. Do not use tool in presence of flammable liquids or gases.

6.KEEP CHILDREN AWAY. All visitors should be kept safe distance from work area.

7.MAKE WORKSHOP KID PROOF with padlocks, master switches, or by removing starter keys.

8.DO NOT FORCE TOOL. It will do the job better and safer at the rate for which it was designed.

9.USE RIGHT TOOL. Do not force tool or attachment to do a job for which it was not designed.

10.WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Nonslip footwear is recommended. Wear protective hair covering to contain long hair.

11.ALWAYS USE SAFETY GLASSES. Also use face or dust mask if cutting operation is dusty. Everyday eyeglasses only have impact resistant lenses, they are NOT safety glasses.

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

13.DO NOT OVERREACH. Keep proper footing and balance at all times.

2

14.MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories.

15.DISCONNECT TOOLS before servicing; when changing accessories such as blades, bits, cutters, and the like.

16.REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure switch is in off position before plugging in.

17.USE RECOMMENDED ACCESSORIES. Consult the owner's manual for recommended accessories. The use of improper accessories may cause risk of injury to persons.

18.NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the cutting tool is unintentionally contacted.

19.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 replaced.

20.DIRECTION OF FEED. Feed work into a blade or cutter against the direction of rotation of the blade or cutter only.

21.NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Do not leave tool until it comes to a complete stop.

22.REPLACEMENT PARTS. When servicing, use only identical replacement parts.

23.POLARIZED PLUGS. To reduce the risk of electric shock, this appliance 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.

VOLTAGE WARNING: Before connecting the tool to a power source (receptacle, outlet, etc.) be sure the voltage supplied is the same as that specified on the nameplate of the tool. A power source with voltage greater than that specified for the tool can result in SERIOUS INJURY to the useras well as damage to the appliance. If in doubt, DO NOT PLUG IN THE APPLIANCE. Using a power source with voltage less than the nameplate rating is harmful to the motor.

USE PROPER EXTENSION CORD. 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. Table 1 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

OPERATION

Cutting operation

CAUTION:

•Never attempt to cut workpieces less than 14 gauge (0.08") thick except pipe or workpieces which cannot be secured firmly with the vise. The piece cut off may be caught by the blade, causing dangerous scattering of chips and/or damage to the carbide-tips. Possible serious injury may result.

•Do not apply excessive pressure on the handle when cutting. Too much pressure may result in overload of the motor, decreased cutting efficiency and/or damage to the carbide-tips or blade itself.

6

•Too little pressure on the handle may result in more sparks and premature blade wear.

•Do not touch the blade, workpiece or cutting chips immediately after operation; they may be extremely hot and could burn your skin.

•If the blade stops during operation, makes an odd noise or begins to vibrate, switch off the tool immediately. Replace cracked or damaged blade

with a new one.

Hold the handle firmly. Switch on the tool and wait until the blade attains full speed. Then lower the handle gently to bring the blade close to the workpiece. When the blade makes contact, ease into the cut gently at first, then gradually add pressure as the cutting position steadies. Your pressure on the handle should be adjusted to produce the minimum amount of sparks.

When the cut is completed, switch off the tool and WAIT UNTIL THE BLADE HAS COME TO A COMPLETE STOP before returning the handle to the fully elevated position. If the handle is raised while the blade is still rotating, the piece cut off may be caught by the blade, causing dangerous scattering of chips. When cutting only part of the way into a workpiece, raise the handle while the blade is rotating. Switching off during the cut may cause damage to the carbide-tips as they contact the workpiece.

Cutting angles

Secure the workpiece in the vise as shown in the Figure A and proceed to cut it. The saw blade life will be shortened if the workpiece is cut as shown in the Fig B.

	A
Fig. A	Fig. B
Fig. C	Fig. D
003782

CAUTION:

•Do NOT cut the workpiece as shown in the Fig. C

since this may cause it to be ejected from the vise, possibly resulting in injury.

The saw blade is subjected to greater wear when the area A in the Fig. B is cut. Place a wooden block up against the workpiece as shown in the Fig. D so that the saw blade will enter area A at an angle. This will help to extend the saw blade life.

The allowable cutting dimensions are reduced when a wooden block is used. Use a wooden block whose dimensions are equivalent to the maximum allowable cutting dimensions minus the dimensions of the workpiece to be cut. This will further minimize the shortening of the saw blade life.

Cutting pipes, squares and channels

The saw blade is subjected to greater wear when the areas A and B in figure F and figure G are cut. Place a wooden block up against the workpiece as shown in figure H and figure I so that the saw blade will enter areas A and B at an angle. This will help to minimize the shortening of the saw blade life.

The allowable cutting dimensions are reduced when a wooden block is used. Use a wooden block whose dimensions are equivalent to the maximum allowable cutting dimensions minus the dimensions of the workpiece to be cut. This will further minimize the shortening of the saw blade life.
