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.

Cordless Metal Cutter 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 expo-sure, blade binding, or loss of control.
5. Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting tool may contact hidden wiring. 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 offcentre, causing loss of control.
8. Never use damaged or incorrect blade wash-ers 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 workpiece 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 work-piece 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.

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.

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 the lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If the saw is accidentally dropped, the lower guard may be bent. Raise the lower guard with the retracting handle and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut.
2. Check the operation of the lower guard spring. If 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 of debris.
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 lower guard should operate automatically.
4. Always observe that the lower guard is covering the blade before placing the saw down on bench 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 does not touch tool housing. Leaving blade exposed is VERY DANGEROUS and can lead to serious personal injury.

Additional safety warnings

1. Do not stop the blades by lateral pressure on the saw blade.
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. 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!
4. Never attempt to make a cut with the tool held upside down in a vise. This is extremely dangerous and can lead to serious accidents.
5. Wear safety goggles and hearing protection during operation.
6. Do not use any abrasive wheels.
7. 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.
8. Always use the saw blade intended for cutting the material that you are going to cut.
9. Only use the saw blades that are marked with a speed equal or higher than the speed marked on the tool.
10. 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.
11. Some material contains chemicals which may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.
12. Wear a dust mask and hearing protection when use the tool.

WARNING: DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to safety rules for the subject product. MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury.

• WARNING: BE SURE TO TIGHTEN THE HEX BOLT CLOCKWISE SECURELY. Also be careful not to tighten the bolt forcibly. Slipping your hand from the hex wrench can cause a personal injury.
• WARNING: If the ring is needed to mount the blade onto the spindle, always be sure that the correct ring for the blade’s arbor hole you intend to use is installed between the inner and the outer flanges. Use of the incorrect arbor hole ring may result in the improper mounting of the blade causing blade movement and severe vibration resulting in possible loss of control during operation and in serious personal injury.

Blade guard cleaning
When changing the circular saw blade, make sure to also clean the upper and lower guards of accumulated metal chips as discussed in the section for maintenance. Such efforts do not replace the need to check lower guard operation before each use.

OPERATION

This tool is intended to cut mild steel only.
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.

• CAUTION: Always wear eye protection or goggle before 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.
• CAUTION: Never twist or force the tool in the cut. This may cause motor overload and/or a dangerous kickback, resulting in serious injury to the operator.
• CAUTION: Always use the circular saw blades appropriate for your job. The use of inappropriate circular saw blades may cause a poor cutting performance and/or present a risk of personal injury.
• CAUTION: Do not use a deformed or cracked circular saw blade. Replace it with a new one.

Checking blade guard function

Remove the battery cartridge and the dust case. Retract the lower guard manually to the end and release it. The lower guard is properly functioning if;

• it is retracted above the base without any hindrance and;
• it automatically returns and contacts with the stopper.

Fig.19: 1. Upper guard 2. Lower guard 3. Base 4. Stopper 5. Open 6. Close If the lower guard is not functioning properly, check if metal chips are accumulated inside of the upper and lower guards. If the lower guard is not functioning prop-erly even after removing metal chips, have your tool serviced at a Makita service center.
Fig.20 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 the tool, they cannot be cut by the circular saw blade. Set the base on the workpiece to be cut without the circular saw blade making any contact. Then turn the tool on and wait until the circular saw blade attains full speed. Now simply move the tool forward over the workpiece surface, keeping it flat and advancing smoothly until the cutting is completed.
To get clean cuts, keep your cutting 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 circular saw blade and lead to dangerous kickback and possible serious injury. Release switch, wait for the circular saw 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 particles being ejected from the tool. Use eye protection to help avoid injury.

• CAUTION: Do not stack materials when cut-ting them.
• CAUTION: Do not cut hardened steel, wood, plastics, concrete, tile, etc. Cut only mild steel and stainless steel with a suitable circular saw blade.
• CAUTION: Do not touch the circular saw blade, workpiece or cutting chips with bare hands immediately after cutting. They may be extremely hot and could burn your skin.
• CAUTION: If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery.

NOTE: When making a miter cuts etc., sometimes the lower guard does not move easily. At that time, use the retracting lever to raise the lower guard for starting cut and as soon as blade enters the material, release the retracting lever.

Fig.21: 1. Retracting lever

Rip fence (Guide rule)

Country specific

CAUTION: Make sure that the rip fence is securely installed in the correct position before use. Improper attachment may cause dangerous kickback.

Fig.22: 1. Rip fence (Guide rule) 2. Clamping screw

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 posi-tion with the clamping screw 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 the battery cartridge is removed before attempting to perform inspection or maintenance.
• CAUTION: Clean out the upper and lower guards to ensure there is no accumulated metal chips which may impede the operation of the lower guarding system. A dirty guarding system may limit the proper operation which could result in serious personal injury. When using compressed air to blow metal chips out of the guards, wear a proper eye and breathing protection.
• CAUTION: After each use, clean up the inside of the dust case and wipe off the metal chips on the tool. Fine metal chips may come inside the tool and cause malfunction or a fire.

To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts.
