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.

Safety instructions for mitre saws 

1. 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 whenever 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. hold-ing the workpiece to the right of the saw blade with your left hand or vice versa is very dangerous.
      1. Fig.1
   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 contacting 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 manual. 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. Do not use the saw to cut other than wood, aluminum or similar materials.
   23.  (For European countries only)
   24. Always use the blade which conforms to EN847-1.

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 damage before operation. Replace cracked or damaged 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.

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

•  Fig.9: 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 operation 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-wise 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.
WARNING: After a cutting operation, do
not raise the saw 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.
WARNING: 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.

•  Fig.38: 1. Support
• 2. Turn base

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.

•  Fig.39: 1. Upper fence
• 2. Lower fence
• 3. Clamping screw
• 4. Adjusting screw

NOTICE: The lower fences are fixed to the base in the factory. Do not remove the lower fences.
NOTICE: If the upper fence is still loose after tightening the clamping screw, turn the adjusting screw to close a gap. The adjusting screw is factory adjusted. You don’t need to use it unless needed.
You can store the upper fences onto the holder when not in use. Use the clip on the upper fence to hold it on the holder.

• 2. Upper fence
• 3. Clip

Vertical vise

WARNING: The workpiece must be secured firmly against the turn base and guide fence with the vise during all operations. If the workpiece is not properly secured against the fence the material may move during the cutting operation causing possible damage to the blade, causing the material to be thrown and loss of control resulting in serious personal injury.

•  Fig.41: 1. Vise arm
• 2. Vise rod
• 3. Clamping screw
• 4. Vise knob

The vertical vise can be installed in two positions on either the left or right side of the base. Insert the vise rod into the hole in the base.
Position the vise arm according to the thickness and shape of the workpiece and secure the vise arm by tightening the screw. If the clamping screw contacts the carriage, install it on the opposite side of vise arm. Make sure that no part of the tool contacts the vise when lowering the handle all the way. If some part contacts the vise, re-position the vise. Press the workpiece flat against the guide fence and the turn base. Position the workpiece at the desired cutting position and secure it firmly by tightening the vise knob.
NOTE: For a quick setting of workpiece, turning the vise knob to 90° counterclockwise allows the vise knob to be moved up and down. To secure the work-piece after setting, turn the vise knob clockwise.

Horizontal vise

WARNING: Always rotate the vise nut clock-wise until the workpiece is properly secured. If the workpiece is not properly secured, the material may move during the cutting operation causing possible damage to the saw blade, causing the material to be thrown and loss of control resulting in serious per-sonal injury.
WARNING: When cutting a thin workpiece, such as base boards, against the fence, always use the horizontal vise.
CAUTION: When cutting the workpiece of the thickness 20 mm or thinner, make sure to use a spacer block to secure the workpiece.

The horizontal vise can be installed in two positions on either the left or right side of the base. When performing 22.5° or greater miter cuts, install the horizontal vise on the side opposite the direction in which the turn base is to be turned.

•  Fig.42: 1. Vise plate
• 2. Vise nut
• 3. Vise knob

By flipping the vise nut counterclockwise, the vise is released, and rapidly moves in and out. To grip the workpiece, push the vise knob forward until the vise plate contacts the workpiece and flip the vise nut clock-wise. Then turn the vise knob clockwise to secure the workpiece.
NOTE: The maximum width of workpiece which can be secured by the horizontal vise is 228 mm.

Holders

WARNING: Always support a long workpiece so it is level with the top surface of the turn base for an accurate cut and to prevent dangerous loss of tool control. Proper workpiece support will help avoid blade pinch and possible kickback which may result in serious personal injury.
To hold long workpieces horizontally, holders are pro-vided on both sides of the tool. Loosen the screws and extend the holders to the appropriate length for holding the workpiece. Then tighten the screws.

OPERATION

This tool is intended to cut wood products. With appropriate Makita genuine saw blades, following materials can also be sawed :

• Aluminum products

Refer to our website or contact your local Makita dealer for the correct circular saw blades to be used for the material to be cut.

• WARNING: Make sure the saw 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.
• WARNING: After a cutting operation, do not raise the saw 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.
• WARNING: Do not perform any adjustment such as turning grip, knob, and levers on the tool while the saw blade is rotating. Adjustment while the blade is rotating may result in serious personal injury.
• CAUTION: Do not release the saw head uncontrolled from the fully down position. Uncontrolled saw head may hit you and it will result in personal injury.
• NOTICE: Before use, be sure to unlock the stopper pin and release the handle from the lowered position.
• NOTICE: 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.
• NOTICE: 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.
• NOTICE: 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.

•  Fig.44: 1. Stopper pin

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

•  Fig.45: 1. Stopper pin

1. Unlock the stopper pin so that the carriage can slide freely.
2. Secure the workpiece with the proper type of vise.

Miter cutting

Refer to the section for adjusting the miter angle.

Bevel cut

WARNING: After setting the blade for a bevel cut, ensure that the carriage and saw 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 operation may result in kickback and serious personal injury.
WARNING: While making a bevel cut, keep hands out of the path of the saw 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.
WARNING: The saw 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 saw blade. If the blade is raised while it is rotating, the cut-off piece may be 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 pressure direction is changed during a cut, the precision of the cut will be impaired.
