- KNOW YOUR POWER TOOL. Read the owner’s manual carefully. Learn the tool’s applications and limitations, as well as the specific potential hazards peculiar to it.
- KEEP GUARDS IN PLACE and in working order.
- REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and adjusting wrenches are removed from tool before turning it on.
- KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
- 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.
- KEEP CHILDREN AWAY. All visitors should be kept safe distance from work area.
- MAKE WORKSHOP KID PROOF with padlocks, master switches, or by removing starter keys.
- DO NOT FORCE TOOL. It will do the job better and safer at the rate for which it was designed.
- USE RIGHT TOOL. Do not force tool or attachment to do a job for which it was not designed.
- 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.
- 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.
- 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.
- DO NOT OVERREACH. Keep proper footing and balance at all times.
- MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories.
- DISCONNECT TOOLS before servicing; when changing accessories such as blades, bits, cutters, and the like.
- REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure switch is in off position before plugging in.
- USE RECOMMENDED ACCESSORIES. Consult the owner’s manual for recommended accessories. The use of improper accessories may cause risk of injury to persons.
- NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the cutting tool is unintentionally contacted.
- 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.
- DIRECTION OF FEED. Feed work into a blade or cutter against the direction of rotation of the blade or cutter only.
- NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Do not leave tool until it comes to a complete stop.
- REPLACEMENT PARTS. When servicing, use only identical replacement parts.
- POLARIZED PLUGS. To reduce the risk of electric shock, this equipment 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 user- as well as damage to the tool. If in doubt, DO NOT PLUG IN THE TOOL. 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.

Specific safety rules
DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to portable cut-off safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.
- Wear hearing protection during extended period of operation.
- Use only wheels having a maximum operating speed at least as high as “No Load RPM” marked on the tool’s nameplate. Use only fiberglass-reinforced cut-off wheels.
- Check the wheel carefully for cracks or damage before operation. Replace cracked or damaged wheel immediately. Run the tool (with guard) at no load for about a minute, holding tool away from others. If wheel is flawed, it will likely separate during this test.
- Secure the wheel carefully.
- Use only flanges specified for this tool.
- Be careful not to damage the spindle, flanges(especially the installing surface) or bolt. Damage to these parts could result in wheel breakage.
- Do not operate the tool without guards in place. Check wheel guard for proper closing before each use. Do not operate the tool if wheel guard does not move freely and close instantly. Never clamp or tie the wheel guard into the open position.
- Hold the handle firmly.
- Keep hands away from rotating parts.
- Make sure the wheel is not contacting the workpiece before the switch is turned on.
- Before using the tool on an actual workpiece, let it run for a while. Watch for vibration or wobbling that could indicate poor installation or a poorly balanced wheel.
- Watch out for flying sparks when operating. They can cause injury or ignite combustible materials.
- Remove material or debris from the area that might be ignited by sparks. Be sure that others are not in the path of the sparks. Keep a proper, charged fire extinguisher closely available.
- Use the cutting edge of the wheel only. Never use side surface.
- Do not attempt to keep the trigger in the ON position.
- If the wheel stops during operation, makes an odd noise or begins to vibrate, switch off the tool immediately.
- Turn off the tool and wait for the wheel to stop before moving workpiece or changing settings.
- Do not touch the workpiece immediately after operation; it is extremely hot and could burn your skin.
- Store wheels in a dry location only.

- 0 – 170 mm (0- 6-11/16) (original setting)
- 35 – 205 mm (1-3/8- 8-1/16)
- 70 – 240 mm (2-3/4- 9-7/16)
If your work requires different setting, proceed as follows to change the spacing or interval.
For LW1400Loosen the screw on the guide plate. Move the guide plate to the desired position then tighten the screw.► 1. Screw 2. Guide plate
For LW1401Remove the two hex bolts using a socket wrench. Move the guide plate to the desired position and secure it with the hex bolts.► 1. Guide plate 2. Hex bolts
Cutting angle adjustmentCAUTION: After adjusting the angle of the guide plate, make sure that the guide plate is properly secured. Insufficient fixing may result in personal injury.
For LW1400Turn the lever counterclockwise. Move the guide plate to the desired angle and fully tighten the lever.► 1. Guide plate 2. Lever
For LW1401NOTICE: When performing right miter cut, always set the guide plate at 0 – 170 mm (06-11/16) position. Setting at the 35 – 205 mm (1-3/8- 8-1/16) or 70 – 240 mm (2-3/4- 9-7/16) position hinders the movement of stopper plate, which results in a failure cut.Loosen the two hex bolts using a socket wrench. Turn the guide plate to the desired angle and secure it with the hex bolts. Be careful not to move the set angle while securing the hex bolts.► 1. Guide plate 2. Hex bolts
NOTE: The scale on the guide plate is only a rough indication. For more accurate angle, use a protractor or triangle ruler. Keep the handle down so that the cut-off wheel extends into the base. At the same time, adjust the angle between the guide plate and the cutoff wheel with a protractor or triangle ruler.
Stopper plateFor LW1401 only (country specific)► 1. Stopper plateThe stopper plate prevents the cut-off wheel from contacting the workbench or floor. When a new cut-off wheel is installed, set the stopper plate to position (A). When the cut-off wheel wears down to the extent that the lower portion of the workpiece is left uncut, set the stopper plate to position (B) to allow increased cutting capacity with a worn down wheel.
ASSEMBLY
CAUTION: Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.
Removing or installing cut-off wheel
CAUTION: Be sure to tighten the toolless clamp or hex bolt securely. Insufficient tightening may result in severe injury. When tightening the hex bolt, use the socket wrench provided with the tool to assure proper tightening.

For LW1401Raise the safety guard. Turn the hex bolt counterclockwise using a socket wrench while holding down the shaft lock. Then remove the hex bolt, outerflange and wheel.
OPERATION
CAUTION: Proper handle pressure during cutting and maximum cutting efficiency can be determined by the amount of sparks that is produced while cutting. Do not force the cut by applying excessive pressure on the handle. Reduced cutting efficiency, premature wheel wear, as well as, possible damage to the tool, cut-off wheel or workpiece may result.Hold the handle firmly. Switch on the tool and wait until the wheel attains full speed before lowering gently into the cut. When the wheel contacts the workpiece, gradually bear down on the handle to perform the cut. When the cut is completed, switch off the tool and wait until the wheel has come to a complete stop before returning the handle to the fully elevated position.

Securing workpiece
CAUTION: Always place the thread holder on the shaft threads when securing the workpiece. Failure to do so may result in insufficient securing of the workpiece. This could cause the workpiece to be ejected or cause a dangerous breakage of the wheel.While the thread holder is lifted, the vise plate can be moved in and out quickly. To grip a workpiece, push the handle until the vise plate contacts the workpiece then return the thread holder. Turn the handle clockwise until the workpiece is securely retained.
► 1. Handle 2. Thread holder 3. Vise plate
When the cut-off wheel has worn down considerably, place a spacer block behind the workpiece as shown in the figure. You can more efficiently utilize the worn wheel by using the mid point on the periphery of the wheel to cut the workpiece. Use a sturdy and non-flammable material for a spacer block.► 1. Spacer block
When cutting workpieces over 85 mm (3-3/8″) wide at an angle, attach a straight piece of wood (spacer) over 190 mm (7-1/2″) long x 45 mm (1-3/4″) wide to the guide plate as shown in the figure. Attach this spacer with screws through the holes in the guide plate. Make sure that the cut-off wheel does not contact the spacer when the tool head is depressed.► 1. Guide plate 2. Spacer block over 190 mm (7-1/2″) long x 45 mm (1-3/4″) wide 3. Workpiece over 85 mm (3-3/8″) wide 4. Vise plate
When the cut-off wheel has worn down, raise the cutting position by putting a spacer block which is slightly narrower than the workpiece as shown in the figure. This will help you to utilize the wheel economically.
