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.

Circular saw safety warnings

Cutting procedures

1. DANGER: Keep hands away from cutting area and the blade. Keep your second hand on auxiliary handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blade.
2. Do not reach underneath the workpiece. The guard cannot protect you from the blade below the workpiece.
3. Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade teeth should be visible below the workpiece.
4. Never hold the workpiece in your hands or across your leg while cutting. Secure the workpiece to a stable platform. It is important to support the work properly to minimise body exposure, blade binding, or loss of control. ► Fig.1
5. Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will also make exposed metal parts of the power tool “live” and could give the operator an electric shock.
6. When ripping, always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance of blade binding.
7. Always use blades with correct size and shape (diamond versus round) of arbour holes. Blades that do not match the mounting hardware of the saw will run off-centre, causing loss of control.
8. Never use damaged or incorrect blade washers or bolt. The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation.

Kickback causes and related warnings
— kickback is a sudden reaction to a pinched, jammed or misaligned saw blade, causing an uncontrolled saw to lift up and out of the workpiece toward the operator;
— when the blade is pinched or jammed tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit rapidly back toward the operator;
— if the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator.
Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.

1. Maintain a firm grip with both hands on the saw and position your arms to resist kickback forces. Position your body to either side of the blade, but not in line with the blade. Kickback could cause the saw to jump backwards, but kickback forces can be controlled by the operator, if proper precautions are taken.
2. When blade is binding, or when interrupting a cut for any reason, release the trigger and hold the saw motionless in the material until the blade comes to a complete stop. Never attempt to remove the saw from the work or pull the saw backward while the blade is in motion or kickback may occur. Investigate and take corrective actions to eliminate the cause of blade binding.
3. When restarting a saw in the workpiece, centre the saw blade in the kerf so that the saw teeth are not engaged into the material. If a saw blade binds, it may walk up or kickback from the workpiece as the saw is restarted.
4. Support large panels to minimise the risk of blade pinching and kickback. Large panels tend to sag under their own weight. Supports must be placed under the panel on both sides, near the line of cut and near the edge of the panel.► Fig.2 ► Fig.3
5. Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and kickback.
6. Blade depth and bevel adjusting locking levers must be tight and secure before making the cut. If blade adjustment shifts while cutting, it may cause binding and kickback.
7. Use extra caution when sawing into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback.
8. ALWAYS hold the tool firmly with both hands. NEVER place your hand, leg or any part of your body under the tool base or behind the saw, especially when making cross-cuts. If kickback occurs, the saw could easily jump backwards over your hand, leading to serious personal injury. ► Fig.4
9. Never force the saw. Push the saw forward at a speed so that the blade cuts without slowing. Forcing the saw can cause uneven cuts, loss of accuracy, and possible kickback.

Lower guard function

1. Check the lower guard for proper closing before each use. Do not operate the saw if thelower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If the saw is accidentallydropped, the lower guard may be bent. Raise thelower guard with the retracting handle and make sure it moves freely and does not touch the bladeor any other part, in all angles and depths of cut.
2. Check the operation of the lower guard springIf the guard and the spring are not operating properly, they must be serviced before use. Lower guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up ofdebris.
3. The lower guard may be retracted manually only for special cuts such as “plunge cuts” and “compound cuts”. Raise the lower guard by the retracting handle and as soon as the blade enters the material, the lower guard must be released. For all other sawing, the lowerguard should operate automatically.
4. Always observe that the lower guard is covering the blade before placing the saw down onbench or floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after switch is released.
5. To check lower guard, open lower guard by hand, then release and watch guard closure. Also check to see that retracting handle doesnot touch tool housing. Leaving blade exposedis VERY DANGEROUS and can lead to serious personal injury.

Additional safety warnings

1. Use extra caution when cutting damp wood, pressure treated lumber, or wood containing knots. Maintain smooth advancement of tool without decrease in blade speed to avoid overheating the blade tips.
2. Do not attempt to remove cut material when blade is moving. Wait until blade stops before grasping cut material. Blades coast after turn off.
3. Avoid cutting nails. Inspect for and remove all nails from lumber before cutting.
4. Place the wider portion of the saw base on that part of the workpiece which is solidly supported, not on the section that will fall off when the cut is made. If the workpiece is short or small, clamp it down. DO NOT TRY TO HOLD SHORT PIECES BY HAND! ► Fig.5
5. Before setting the tool down after completing a cut, be sure that the guard has closed and the blade has come to a complete stop.
6. Never attempt to saw with the circular saw held upside down in a vise. This is extremely dangerous and can lead to serious accidents. ► Fig.6
7. Some material contains chemicals which may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data. 8. Do not stop the blades by lateral pressure on the saw blade.
8. Do not use any abrasive wheels.
9. 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.
10. Keep blade sharp and clean. 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.
11. Wear a dust mask and hearing protection when use the tool.
12. Always use the saw blade intended for cutting the material that you are going to cut.
13. Only use the saw blades that are marked with a speed equal or higher than the speed marked on the tool.
14. (For European countries only) Always use the blade which conforms to EN847-1.

Next, mount the inner flange onto the mounting shaft so that the correct side of protrusion on the inner flange faces outward and then place saw blade and outer flange.
BE SURE TO TIGHTEN THE HEX BOLT CLOCKWISE SECURELY.
CAUTION:

• Make sure that the protrusion “a” on the inner flange that is positioned outside fits into the saw blade hole “a” perfectly.
  Mounting the blade on the wrong side can result in the dangerous vibration.
  ► Fig.17: 1. Ring 2. Inner flange 3. Saw blade 4. Outer flange 5. Hex bolt
  When changing blade, make sure to also clean upper and lower blade guards of accumulated sawdust. Such efforts do not, however, replace the need to check lower guard operation before each use.

Hex wrench storage

► Fig.18: 1. Hex wrench
When not in use, store the hex wrench as shown in the figure to keep it from being lost.
Connecting a vacuum cleaner
► Fig.19: 1. Dust nozzle 2. Screw
► Fig.20: 1. Vacuum cleaner 2. Hose
When you wish to perform clean cutting operation, connect a Makita vacuum cleaner to your tool. Install the dust nozzle on the tool using the screw. Then connect a hose of
the vacuum cleaner  to the dust nozzle as shown in the figure.

OPERATION

CAUTION:

• Be sure to move the tool forward in a straight line gently. Forcing or twisting the tool will result in overheating the motor and dangerous kickback, possibly causing severe injury.
• Always use a front grip and rear handle and firmly hold the tool by both front grip and rear handle during operations.

Hold the tool firmly. The tool is provided with both a front grip and rear handle. Use both to best grasp the tool. If both hands are holding saw, they cannot be cut by the
blade. Set the base on the workpiece to be cut without the blade making any contact. Then turn the tool on and wait until the blade attains full speed. Now simply move the tool forward over the workpiece surface, keeping it flat and advancing smoothly until the sawing is completed.
To get clean cuts, keep your sawing line straight and your speed of advance uniform. If the cut fails to properly follow your intended cut line, do not attempt to turn or force the tool back to the cut line. Doing so may bind the blade and lead to dangerous kickback and possible serious injury. Release switch, wait for blade to stop and then withdraw tool. Realign tool on new cut line, and start cut again. Attempt to avoid positioning which exposes operator to chips and wood dust being ejected from saw. Use eye protection to help avoid injury. ► Fig.21
Rip fence (Guide rule)
► Fig.22: 1. Clamp lever 2. Rip fence (Guide rule)
The handy rip fence allows you to do extra-accurate straight cuts. Simply slide the rip fence up snugly against the side of the workpiece and secure it in position with the clamp lever on the front of the base. It also makes repeated cuts of uniform width possible.

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.

• Clean out the guard to ensure there is noaccumulated sawdust and chips which may impede the operation of the guarding system. A dirty guarding system may limit the proper operation which could result in serious personal injury. The most effective way to accomplish this cleaning is with compressed air.
  If the dust is being blown out of the guard, be sure the proper eye and breathing protection is used.

• Never use gasoline, benzine, thinner, alcoholor the like. Discoloration, deformation or cracks may result.

Adjusting for accuracy of 0° and 45° cut (vertical and 45° cut)
► Fig.23: 1. Adjusting screw for 0° 2. Adjusting screw for 45°
► Fig.24: 1. Triangular rule
This adjustment has been made at the factory. But if it is off, adjust the adjusting screws with a hex wrench while inspecting 0° or 45° the blade with the base using a
triangular rule or square rule, etc.
Adjusting for parallelism
► Fig.25: 1. Base 2. Screw 3. Saw blade
The parallelism between the blade and the base has been factory adjusted. But if it is off, you can adjust it as the following procedure.
Make sure all levers and screws are tightened. Slightly loosen the screw as illustrated. While opening the lower guard, move the rear of base so that the distance A and
B are equal. After adjusting, tighten the screw. Make a test cut to get a correct parallelism.
Replacing carbon brushes
► Fig.26: 1. Limit mark
Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep the carbon brushes clean and free to slip in the holders. Both carbon brushes should be replaced at the same time. Use only identical carbon brushes. Use a screwdriver to remove the brush holder caps. Take out the worn carbon brushes, insert the new ones and secure the brush holder caps.
► Fig.27: 1. Screwdriver 2. Brush holder cap
After replacing brushes, plug in the tool and break in brushes by running tool with no load for about 10 minutes. Then check the tool while running and electric brake operation when releasing the switch trigger. If the electric brake is not working correctly, have the tool repaired by a Makita service center.
To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized Service Centers, always using
Makita replacement parts.
