SAFETY WARNINGS

General power tool safety warnings

WARNING:
Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or BATTERY operated (cordless) power tool.
Work area safety

1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
2. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical Safety

1. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

2. Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of elec-tric shock if your body is earthed or grounded.

3. Do not expose power tools to rain or wet con-ditions. Water entering a power tool will increase the risk of electric shock.

4. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

5. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

6. If operating a power tool in a damp location is unavoidable, use a Residual Current Device
   (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

7. Power tools can produce electromagnetic fields (EMF) that are not harmful to the user. However, users of pacemakers and other similar medical devices should contact the maker of their device and/or doctor for advice before operating this power tool.

8. Do not touch the power plug with wet hands.

9. If the cord is damaged, have it replaced by the manufacturer or his agent in order to avoid a safety hazard.

Personal Safety

1. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
2. Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
3. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or BATTERY pack, pick-ing up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
4. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
5. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewel-lery or long hair can be caught in moving parts.
7.  If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
8. Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
9. Always wear protective goggles to protect your eyes from injury when using power tools. The goggles must comply with ANSI Z87.1 in the USA.
   It is an employer’s responsibility to enforce the use of appropriate safety protective equipments by the tool operators and by other per-sons in the immediate working area.

Power tool use and care

1. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
2. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
3. Disconnect the plug from the power source and/or remove the BATTERY pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
5. Maintain power tools and accessories. Check for misalignment or binding of moving parts, break-age of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits etc. in accordance with these instructions, tak-ing into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
8. Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
9. When using the tool, do not wear cloth work gloves which may be entangled. The entangle-ment of cloth work gloves in the moving parts may result in personal injury.

Service

1. Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
2. Follow instruction for lubricating and changing accessories.

Additional instructions

1. 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.
2. 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.
3. 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.

Safety instructions for mitre saws

1. Mitre saws are intended to cut wood or wood-like products, they cannot be used with abrasive cut-off wheels for cutting ferrous material such as bars, rods, studs, etc. Abrasive dust causes moving parts such as the lower guard to jam. Sparks from abrasive cutting will burn the lower guard, the kerf insert and other plastic parts.

2. Use clamps to support the workpiece when-ever possible. If supporting the workpiece
   by hand, you must always keep your hand at least 100 mm from either side of the saw blade. Do not use this saw to cut pieces that are too small to be securely clamped or held by hand. If your hand is placed too close to the saw blade, there is an increased risk of injury from blade contact.

3. The workpiece must be stationary and clamped or held against both the fence and the table. Do not feed the workpiece into the blade or cut “freehand” in any way. Unrestrained
   or moving workpieces could be thrown at high speeds, causing injury.

4. Push the saw through the workpiece. Do not pull the saw through the workpiece. To make a cut, raise the saw head and pull it out over the workpiece without cutting, start the motor, press the saw head down and push the saw through the workpiece. Cutting on the pull stroke is likely to cause the saw blade to climb on top of the workpiece and violently throw the blade assembly towards the operator.

5. Never cross your hand over the intended line of cutting either in front or behind the saw blade. Supporting the workpiece “cross handed”
   i. e. holding the workpiece to the right of the saw blade with your left hand or vice versa is very dangerous.

6. Do not reach behind the fence with either hand closer than 100 mm from either side of the saw blade, to remove wood scraps, or for any other reason while the blade is spinning. The proximity of the spinning saw blade to your hand may not be obvious and you may be seriously injured.

7. Inspect your workpiece before cutting. If the workpiece is bowed or warped, clamp it with the outside bowed face toward the fence. Always make certain that there is no gap between the workpiece, fence and table along the line of the cut. Bent or warped workpieces can twist or shift and may cause binding on the spinning saw blade while cutting. There should be no nails or foreign objects in the workpiece.

8. Do not use the saw until the table is clear of all tools, wood scraps, etc., except for the work-piece. Small debris or loose pieces of wood or other objects that contact the revolving blade can be thrown with high speed.

9. Cut only one workpiece at a time. Stacked multiple workpieces cannot be adequately clamped or braced and may bind on the blade or shift during cutting.

10. Ensure the mitre saw is mounted or placed on a level, firm work surface before use. A level and firm work surface reduces the risk of the mitre saw becoming unstable.

11.  Plan your work. Every time you change the bevel or mitre angle setting, make sure the adjustable fence is set correctly to support the workpiece and will not interfere with the blade or the guarding system. Without turning the tool “ON” and with no workpiece on the table, move the saw blade through a complete simulated cut to assure there will be no interference or danger of cutting the fence.

12. Provide adequate support such as table extensions, saw horses, etc. for a workpiece that is wider or longer than the table top. Workpieces longer or wider than the mitre saw table can tip if not securely supported. If the cut-off piece or workpiece tips, it can lift the lower guard or be thrown by the spinning blade.

13. Do not use another person as a substitute for a table extension or as additional support. Unstable support for the workpiece can cause the blade to bind or the workpiece to shift during the cutting operation pulling you and the helper into the spinning blade.

14. The cut-off piece must not be jammed or pressed by any means against the spinning saw blade. If confined, i.e. using length stops, the cut-off piece could get wedged against the blade and thrown violently.

15. Always use a clamp or a fixture designed to properly support round material such as rods or tubing. Rods have a tendency to roll while being cut, causing the blade to “bite” and pull the work with your hand into the blade.

16. Let the blade reach full speed before contact-ing the workpiece. This will reduce the risk of the workpiece being thrown.

17. If the workpiece or blade becomes jammed, turn the mitre saw off. Wait for all moving parts to stop and disconnect the plug from the power source and/or remove the battery pack. Then work to free the jammed material. Continued sawing with a jammed workpiece could cause loss of control or damage to the mitre saw.

18. After finishing the cut, release the switch, hold the saw head down and wait for the blade to stop before removing the cut-off piece. Reaching with your hand near the coasting blade is dangerous.

19. Hold the handle firmly when making an incomplete cut or when releasing the switch before the saw head is completely in the down position. The braking action of the saw may cause the saw head to be suddenly pulled downward, causing a risk of injury.

20. Only use the saw blade with the diameter that is marked on the tool or specified in the man-ual. Use of an incorrectly sized blade may affect the proper guarding of the blade or guard operation which could result in serious personal injury.

21. Only use the saw blades that are marked with a speed equal or higher than the speed marked on the tool.

22. Always select the correct saw blade for the material to be cut. Do not use the saw blade to cut materials other than those specified.

23. The saw can cut wood, aluminum or similar materials, when using a saw blade appropriate for the material. Do not use the saw to cut the other material, including magnesium, steel and iron.

Additional instructions

1. Make workshop kid proof with padlocks.
2. Never stand on the tool. Serious injury could occur if the tool is tipped or if the cutting tool is unintentionally contacted.
3. Never leave the tool running unattended. Turn the power off. Do not leave tool until it comes to a complete stop.
4. Do not operate saw without guards in place. Check blade guard for proper closing before each use. Do not operate saw if blade guard does not move freely and close instantly. Never clamp or tie the blade guard into the open position.
5. Keep hands out of path of saw blade. Avoid contact with any coasting blade. It can still cause severe injury.
6. To reduce the risk of injury, return carriage to the full rear position after each crosscut operation.
7. Always secure all moving portions before carrying the tool.
8. Stopper pin which locks the cutter head down is for carrying and storage purposes only and not for any cutting operations.
9. Check the blade carefully for cracks or dam-age before operation. Replace cracked or dam-aged blade immediately. Gum and wood pitch hardened on blades slows saw and increases potential for kickback. Keep blade clean by first removing it from tool, then cleaning it with gum and pitch remover, hot water or kerosene. Never use gasoline to clean blade.
10. While making a slide cut, KICKBACK can occur. KICKBACK occurs when the blade binds in the workpiece during a cutting operation and the saw blade is driven rapidly towards the operator. Loss of control and serious personal injury can result. If blade begins to bind during a cutting operation, do not continue to cut and release switch immediately.
11. Use only flanges specified for this tool.
12. Be careful not to damage the arbor, flanges (especially the installing surface) or bolt. Damage to these parts could result in blade breakage.
13. Make sure that the turn base is properly secured so it will not move during operation. Use the holes in the base to fasten the saw to a stable work platform or bench. NEVER use tool where operator positioning would be awkward.
14. Make sure the shaft lock is released before the switch is turned on.
15. Be sure that the blade does not contact the turn base in the lowest position.
16. Hold the handle firmly. Be aware that the saw moves up or down slightly during start-up and stopping.
17. Make sure the blade is not contacting the workpiece before the switch is turned on.
18. 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 blade.
19. Stop operation immediately if you notice any-thing abnormal.
20. Do not attempt to lock the trigger in the “ON” position.
21. Always use accessories recommended in this manual. Use of improper accessories such as abrasive wheels may cause an injury.
22. Some material contains chemicals which may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.

Additional safety rules for the laser

1. LASER RADIATION DO NOT STARE INTO BEAM.
2. AVOID EXPOSURE – LASER RADIATION IS EMITTED FROM APERTURE.
3. USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

FUNCTIONAL DESCRIPTION

WARNING:
Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool. Failure to switch off and unplug the tool may result in serious personal injury from accidental start-up.

Blade guard

1. Blade guard

• When lowering the handle, the blade guard rises automatically. The guard is spring loaded so it returns to its original position when the cut is completed and the handle is raised.
  WARNING: Never defeat or remove the blade guard or the spring which attaches to the guard. An exposed blade as a result of defeated guarding may result in serious personal injury during operation.

• In the interest of your personal safety, always maintain the blade guard in good condition. Any irregular opera-tion of the blade guard should be corrected immediately. Check to assure spring loaded return action of guard.
  WARNING: Never use the tool if the blade guard or spring are damaged, faulty or removed. Operation of the tool with a damaged, faulty or removed guard may result in serious personal injury.

• If the see-through blade guard becomes dirty, or saw-dust adheres to it in such a way that the blade and/or workpiece is no longer easily visible, unplug the saw and clean the guard carefully with a damp cloth. Do not use solvents or any petroleum-based cleaners on the plastic guard because this may cause damage to the guard.

• If the blade guard is especially dirty and vision through the guard is impaired, unplug the tool and use the sup-plied wrench to loosen the hex bolt holding the center cover. Loosen the hex bolt by turning it counterclockwise and raise the blade guard and center cover. With the blade guard so positioned, cleaning can be more completely and efficiently accomplished.

• When cleaning is complete, reverse procedure above and secure bolt. Do not remove spring holding blade guard. If guard becomes discolored through age or UV light exposure, contact a Makita service center for a new guard. DO NOT DEFEAT OR REMOVE GUARD.

Securing workpiece

WARNING:

• It is extremely important to always secure the workpiece correctly with the proper type of vise or crown molding stoppers. Failure to do so may result in serious personal injury and cause damage to the tool and/or the workpiece.
• After a cutting operation do not raise the blade until it has come to a complete stop. The raising of a coasting blade may result in serious personal injury and damage to the workpiece.
• When cutting a workpiece that is longer than the support base of the saw, the material should be supported the entire length beyond the support base and at the same height to keep the material level.

Proper workpiece support will help avoid blade pinch and possible kickback which may result in serious personal injury. Do not rely solely on the vertical vise and/or horizontal vise to secure the workpiece. Thin material tends to sag. Support workpiece over its entire length to avoid blade pinch and possible KICKBACK.

Guide fences
WARNING: Before operating the tool, make sure that the upper fence is secured firmly.
WARNING: Before bevel-cutting, make sure that no part of the tool, especially the blade, contacts the upper and lower fences when fully lowering and raising the handle in any position and while moving the carriage through its full range of travel. If the tool or blade makes contact with
the fence this may result in kickback or unexpected movement of the material and serious personal injury.
Use upper fences to support the material higher than the lower fences. Insert the upper fence into the hole on the lower fence and tighten the clamping screw.

OPERATION

WARNING:

• Make sure the blade is not contacting the workpiece, etc. before the switch is turned on. Turning the tool on with the blade in contact with the workpiece may result in kickback and serious personal injury.
• After a cutting operation, do not raise the blade until it has come to a complete stop. The raising of a coasting blade may result in serious personal injury and damage to the workpiece.
• Do not perform any adjustment such as turning grip, knob, and levers on the tool while the blade is rotating. Adjustment while the blade is rotating may result in serious personal injury.

NOTICE:

• Before use, be sure to unlock the stop-per pin and release the handle from the lowered position.
• Do not apply excessive pressure on the handle when cutting. Too much force may result in overload of the motor and/or decreased cutting efficiency. Press down handle with only as much force as necessary for smooth cutting and without significant decrease in blade speed.
• Gently press down the handle to per-form the cut. If the handle is pressed down with force or if lateral force is applied, the blade may vibrate and leave a mark (saw mark) in the workpiece and the precision of the cut may be impaired.
• During a slide cut, gently push the carriage toward the guide fence without stopping. If the carriage movement is stopped during the cut, a mark will be left in the workpiece and the precision of the cut will be impaired.

Press cutting

WARNING: Always lock the sliding movement of the carriage when performing a press cutting. Cutting without lock may cause possible kickback which may result in serious personal injury.
Workpieces up to 92 mm (3-5/8″) high and 183 mm (7-1/4″) wide can be cut in the following manner.

1. Stopper pin

• Push the carriage toward the guide fence until it stops and lock it with the stopper pin.
• Secure the workpiece with the proper type of vise.
• Switch on the tool without the blade making any contact and wait until the blade attains full speed before lowering.
• Gently lower the handle to the fully lowered position to cut the workpiece.
• When the cut is completed, switch off the tool and wait until the blade has come to a complete stop before returning the blade to its fully elevated position.

Slide (push) cutting (cutting wide workpieces)

WARNING: Whenever performing a slide cut, first pull the carriage full towards you and press the handle all the way down, then push the car-riage toward the guide fence. Never start the cut with the carriage not pulled fully toward you. If you perform the slide cut without the carriage pulled fully toward you unexpected kickback may occur and serious personal injury may result.
WARNING: Never attempt to perform a slide cut by pulling the carriage towards you. Pulling the carriage towards you while cutting may cause unexpected kickback resulting in possible serious personal injury.
WARNING: Never perform the slide cut with the handle locked in the lowered position.

1. Stopper pin

• Unlock the stopper pin so that the carriage can slide freely.
• Secure the workpiece with the proper type of vise.
• Pull the carriage toward you fully.
• Switch on the tool without the blade making any contact and wait until the blade attains full speed.
• Press the handle down and push the carriage toward the guide fence and through the workpiece.
• When the cut is completed, switch off the tool and wait until the blade has come to a complete stop before returning the blade to its fully elevated position.

Miter cutting
Refer to the previously covered “Adjusting the miter angle”.

Bevel cut

WARNING:

• After setting the blade for a bevel cut, ensure that the carriage and blade will have free travel throughout the entire range of the intended cut before operating the tool. Interruption of the carriage or blade travel during the cutting oper-ation may result in kickback and serious personal injury.
• While making a bevel cut keep hands out of the path of the blade. The angle of the blade may confuse the operator as to the actual blade path while cutting and contact with the blade will result in serious personal injury
•  The blade should not be raised until it has come to a complete stop. During a bevel cut the piece cut off may come to rest against the blade. If the blade is raised while it is rotating the cut-off piece maybe ejected by the blade causing the material to fragment which may result in serious personal injury.

NOTICE: When pressing down the handle, apply pressure in parallel with the blade. If a force is applied perpendicularly to the turn base or if the pres-sure direction is changed during a cut, the precision of the cut will be impaired.

1. Remove the upper fence on the side that you are going to tilt the carriage.
2. Unlock the stopper pin.
3. Adjust the bevel angle according to the procedure explained in the “Adjusting the bevel angle” section. Then tighten the knob.
4. Secure the workpiece with a vise.
5. Pull the carriage toward you fully.
6. Switch on the tool without the blade making any contact and wait until the blade attains full speed.
7. Gently lower the handle to the fully lowered position while applying pressure in parallel with the blade and push the carriage toward the guide fence to cut the workpiece.
8. When the cut is completed, switch off the tool and wait until the blade has come to a complete stop before returning the blade to its fully elevated position.

Compound cutting

Compound cutting is the process in which a bevel angle is made at the same time in which a miter angle is being cut on a workpiece. Compound cutting can be performed at the angle shown in the table.

When performing compound cutting, refer to “Press cut-ting”, “Slide (push) cutting”, “Miter cutting” and “Bevel cut” explanations
