USE RIGHT TOOL. Don’t force a 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 jewellery that may get caught in moving parts. Nonslip footwear is recommended. Wear a protective hair covering to contain long hair.
ALWAYS USE SAFETY GLASSES. Also, use a face or dust mask if the cutting operation is dusty. Everyday eyeglasses only have impact-resistant lenses, they are NOT safety glasses.
SECURE WORK. Use clamps or a vice to hold work when practical. It’s safer than using your hand and it frees both hands to operate the tool.
DON’T OVERREACH. Keep proper footing and balance at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for the best and safest performance. Follow instructions for lubricating and changing accessories.
DISCONNECT BATTERY FROM TOOL before servicing; when changing accessories such as blades, bits, cutters, and the like.
REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure the switch is in the off position before inserting the battery.
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. Don’t leave the tool until it comes to a complete stop.

ADDITIONAL SAFETY RULES
DO NOT let comfort or familiarity with the product (gained from repeated use) replace strict adherence to mitre saw safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.

Wear eye protection.
Keep hands out of the path of the saw blade. Avoid contact with any coasting blade. It can still cause severe injury.
Do not operate the saw without guards in place. Check the blade guard for proper closing before each use. Do not operate the saw if the blade guard does not move freely and close instantly. Never clamp or tie the blade guard into the open position.
Do not perform any operation freehand. The workpiece must be secured firmly against the turn base and guide fence with a vice during all operations. Never use your hand to secure the workpiece.
Never reach around the saw blade.
Turn off the tool and wait for the saw blade to stop before moving the workpiece or changing settings.
Remove the battery from the tool before changing the blade or servicing.
Always secure all moving portions before carrying the tool.
Be aware that this tool is always in an operating condition because it does not have to be plugged into an electrical outlet.
Do not use the tool in the presence of flammable liquids or gases.
Check the blade carefully for cracks or damage before operation. Replace cracked or damaged blades immediately. Gum and wood pitch hardened on blades slows the saw and increases the potential for kickback. Keep the blade clean by first removing it from the tool, then cleaning it with gum and pitch remover, hot water or kerosene. Never use gasoline to clean the blade.
Use only the flanges specified for this tool.
Be careful not to damage the arbour, flanges (especially the installing surface) or bolt. Damage to these parts could result in blade breakage.
Make sure that the turn base is properly secured so it will not move during opera-tion. Use the holes in the base to fasten the saw to a stable work platform or bench. NEVER use a tool where operator positioning would be awkward.
For your safety, remove the chips, small pieces, etc. from the tabletop before oper-ation.
Avoid cutting nails. Inspect for and remove all nails from the workpiece before operation.
Make sure the shaft lock is released before the switch is turned on.
Be sure that the blade does not contact the turn base in the lowest position.
Hold the handle firmly. Be aware that the saw moves up or down slightly during start-up and stopping.
Make sure the blade 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 blade.
Wait until the blade attains full speed before cutting.
Stop the operation immediately if you notice anything abnormal.
Do not attempt to lock the trigger in the on position.
Be alert at all times, especially during repetitive, monotonous operations. Do not be lulled into a false sense of security. Blades are extremely unforgiving.
Always use the accessories recommended in this manual. Use of improper accessories such as abrasive wheels may cause an injury.
NEVER hold the workpiece on the right side of the blade with the left hand or vice versa. This is called cross-armed cutting and exposes the user to the risk of SERIOUS PERSONAL INJURY as shown in the figure. ALWAYS use vise to secure the workpiece.
NEVER stack workpieces on the tabletop to speed cutting operations. Cut only one piece at a time.
Some materials contain chemicals that may be toxic. Take caution to prevent dust inhalation and skin contact. Follow mate-rial supplier safety data.

If you leave the battery cartridge in the charger after the charging cycle is complete, the charger will switch into its “ trickle charge (maintenance charge)” mode which will last approximately 24 hours.
After charging, unplug the charger from the power source.

NOTE:

The battery charger is for charging the Makita battery cartridge. Never use it for other purposes or for other manufacturer’s batteries.
When you charge a new battery cartridge or a battery cartridge that has not been used for a long period, it may not accept a full charge. This is a normal condition and does not indicate a problem. You can recharge the battery cartridge fully after discharging it completely and recharging it a couple of times.
If you charge a battery cartridge from a just-operated tool or battery cartridge that has been left in a location exposed to direct sunlight for a long time, the charging light may flash in red colour. If this occurs, wait for a while.
Charging will begin after the battery cartridge is cooled by the cooling fan installed in the charger. (DC24SA only) When the temperature on the battery is more than approx. 70°C, two charging lights may flash in red colour, and when approx. 50°C – 70°C, one charging light in red colour.
If the charging light flashes alternately in green and red colour, charging is not possible. The terminals on the charger or battery cartridge are clogged with dust or the battery cartridge is worn out or damaged.

Cooling system (DC24SA only)

This charger is equipped with a cooling fan for a heated battery to enable the battery to prove its performance. The sound of cooling air comes out during cooling, which means no trouble on the charger.
The yellow light will flash for a warning in the following cases.
- Trouble with cooling fan
- Incomplete cooldown of battery, such as being clogged with dust
The battery can be charged despite the yellow warning light. But the charging time will be longer than usual in this case.
Check the sound of the cooling fan, vent on the charger and battery, which can be sometimes clogged with dust.
The cooling system is in order although no sound of a cooling fan comes out if the yellow warning light will not flash.
Always keep the vent on the charger and battery for cooling.
The products should be sent to repair or maintenance if the yellow warning light frequently flashes.

Conditioning charge (DC24SA only)
Conditioning charge can extend the life of the battery by auto-matically searching the optimum charging condition for the batteries in every situation.

The battery employed in the following conditions repeatedly will be worn out shortly, and a yellow warning light may flash.

Recharge of battery with its high-temperature
Recharge of battery with its low-temperature
Recharge of fully charged battery
Over-discharge of battery (continue to discharge the battery despite the down of power.)

The charging time of such a battery is longer than usual.

Trickle charge (Maintenance charge)
If you leave the battery cartridge in the charger to prevent spontaneous discharging after a full charge, the charger will switch into its “trickle charge (maintenance charge)” mode and keep the battery cartridge fresh and fully charged.

Tips for maintaining maximum battery life

Charge the battery cartridge before completely dis-charged. Always stop tool operation and charge the battery car-tridge when you notice less tool power.
Never recharge a fully charged battery cartridge. Overcharging shortens the battery service life.
Charge the battery cartridge at room temperature at 10°C – 40°C (50°F – 104°F). Let a hot battery cartridge cool down before charging it.
Charge the Nickel Metal Hydride battery cartridge when you do not use it for more than six months.

Blade guard
When lowering the handle, the blade guard rises automati-cally. The guard is spring-loaded so it returns to its original position when the cut is completed and the handle is raised. NEVER DEFEAT OR REMOVE THE BLADE GUARD OR THE SPRING THAT ATTACHES TO THE GUARD.

In the interest of your safety, always maintain the blade guard in good condition. Any irregular operation of the blade guard should be corrected immediately. Check to ensure the spring-loaded return action of the guard. NEVER USE THE TOOL IF THE BLADE GUARD OR SPRING ARE DAM-AGED, FAULTY OR REMOVED. DOING SO IS HIGHLY DANGEROUS AND CAN CAUSE SERIOUS PERSONAL INJURY.

If the see-through blade guard becomes dirty, or sawdust adheres to it in such a way that the blade is no longer easily visible, remove the battery cartridge and clean the guard carefully with a damp cloth. Do not use solvents or any petro-leum-based cleaners on the plastic guard. If the blade guard is especially dirty and vision through the guard is impaired, use the supplied socket wrench to loosen the hex bolt holding the centre cover. Loosen the hex bolt by turning it counterclockwise and raise the blade guard and centre cover. With the blade guard so positioned, cleaning can be more completely and efficiently accomplished. When cleaning is complete, reverse the procedure above and secure the bolt. Do not remove the spring holding blade guard. If the guard becomes discoloured through age or UV light exposure, contact a Makita service centre for a new guard. DO NOT DEFEAT OR REMOVE GUARD.

Positioning kerf board

This tool is provided with the kerf boards in the turn base to minimize tearing on the exit side of a cut. The kerf boards are factory-adjusted so that the saw blade does not contact the kerf boards. Before use, adjust the kerf boards as follows:
First, remove the battery cartridge. Loosen all the screws (2 each on the left and right) securing the kerf boards. Re-tighten them only to the extent that the kerf boards can still be easily moved by hand. Lower the handle fully and push in the stop-per pin to lock the handle in the lowered position. Adjust the kerf boards so that the kerf boards just contact the sides of the blade teeth. Tighten all the screws (do not tighten firmly). After adjusting the kerf boards, release the stopper pin and raise the handle. Then tighten all the screws securely.

CAUTION:
Always support long workpieces level with the top surface of the turn base for accurate cuts and to prevent dangerous loss of control of the tool.

OPERATION

CAUTION:

Before use, be sure to release the handle from the lowered position by pulling the stopper pin.
Make sure the blade is not contacting the workpiece, etc. before the switch is turned on.
Do not apply excessive pressure on the handle when cutting. Too much force may result in an overload of the motor and/or decreased cutting efficiency. Push down the handle with only as much force as is necessary for smooth cutting and without a significant decrease in blade speed.
Gently press down the handle to perform the cut. If the handle is pressed down with force or if lateral force is applied, the blade will vibrate and leave a mark (saw mark) in the workpiece and the precision of the cut will be impaired.

Press cutting
Secure the workpiece with the vise. Switch on the tool without the blade making any contact and wait until the blade attains full speed before lowering. Then 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.
Miter cutting
Refer to the previously covered “Adjusting the miter angle”.
Bevel cut
Loosen the lever and tilt the saw blade to set the bevel angle (Refer to the previously covered “Adjusting the bevel angle”). Be sure to retighten the lever firmly to secure the selected bevel angle safely. Secure the work-piece with a vise. Switch on the tool without the blade making any contact and wait until the blade attains full speed. Then gently lower the handle to the fully lowered position while applying pressure in parallel with the blade. 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. CAUTION:
- Always be sure that the blade will move down to the bevel direction during a bevel cut. Keep hands out of the path of the saw blade.
- During a bevel cut, it may create a condition whereby the piece cut off will come to rest against the side of the blade. If the blade is raised while the blade is still rotating, this piece may be caught by the blade, causing fragments to be scattered which is dangerous. The blade should be raised ONLY after the blade has come to a complete stop.
- When pressing the handle down, apply pressure parallel to the blade. If the pressure is not parallel to the blade during a cut, the angle of the blade might be shifted and the precision of the cut will be impaired.
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.Miter angle| Bevel angle
---|---
Left and Right 45˚| Left 0 – 45˚
Left and Right 52˚| Left 0 – 40˚

When performing compound cutting, refer to “Press cut-ting”, “Miter cutting” and “Bevel cut” explanations.

Cutting crown and cove mouldings
Crown and cove mouldings can be cut on a compound miter saw with the mouldings laid flat on the turn base. There are two common types of crown mouldings and one type of cove moulding; 52/38° wall angle crown moulding, 45° wall angle crown moulding and 45° wall angle cove moulding. See illustrations.
52/38° type crown moulding
45° type crown molding
45° type cove molding

There are crown and cove moulding joints that are made to fit “Inside” 90° corners ((1) and (2) in Fig. A) and “Outside” 90° corners ((3) and (4) in Fig. A).

Inside corner
Outside corner

Measuring
Measure the wall length and adjust the workpiece on the table to cut the wall contact edge to the desired length. Always make sure that the cut workpiece length at the back of the workpiece is the same as the wall length. Adjust the cut length for the angle of the cut. Always use several pieces for test cuts to check the saw angles. When cutting crown and cove mouldings, set the bevel angle and miter angle as indicated in Table (A) and position the mouldings on the top surface of the saw base as indicated in Table (B).

Example:
In the case of cutting 52/38° type crown moulding for the position (1) in Fig. A:

Tilt and secure the bevel angle setting to 33.9°LEFT.
Adjust and secure the miter angle setting to 31.6°RIGHT.
Lay crown moulding with its broad back (hidden) surface down on the turn base with its CEILING CONTACT EDGE against the guide fence on the saw.
The finished piece to be used will always be on the LEFT side of the blade after the cut has been made.

Cutting repetitive lengths
When cutting several pieces of stock to the same length, ranging from 220 mm (8-5/8”) to 365 mm (14-3/8”), the use of the set plate (optional accessory) will facilitate more efficient operation. Install the set plate on the holder (optional accessory) as shown in the figure. Align the cutting line on your workpiece with either the left or right side of the groove in the kerf board and while holding the workpiece from moving, move the set plate flush against the end of the workpiece. Then secure the set plate with the screw. When the set plate is not used, loosen the screw and turn the set plate out of the way.

NOTE:
Use of the holder-rod assembly (optional accessory) allows cutting repetitive lengths up to 2,200 mm (7.2 ft.) approximately.

Carrying tool
Make sure that the battery cartridge is removed. Secure the blade at 0° bevel angle and the turn base at the right miter angle fully. Lower the handle fully and lock it in the lowered position by pushing in the stopper pin.

Carry the tool by carrying a grip as shown in the figure. If you remove the holders, dust bags, etc., you can carry the tool more easily.

CAUTION:

Always secure all moving portions before carrying the tool.
The stopper pin is for carrying and storage purposes only and not for any cutting operations.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance.

WARNING:
Always be sure that the blade is sharp and clean for the best and safest performance.

Adjusting the cutting angle
This tool is carefully adjusted and aligned at the factory, but rough handling may have affected the alignment. If your tool is not aligned properly, perform the following:

Miter angle

Loosen the grip which secures the turn base. Turn the turn base so that the pointer points to 0° on the mitre scale. Then turn the turn base slightly clockwise and counterclockwise to seat the turn base in the 0° miter notch. (Leave as it is if the pointer does not point to 0°.) Loosen the hex bolts securing the guide fence using the socket wrench.

Make sure that the pointer on the arm points to 45° on the bevel scale on the arm holder. If the pointer does not point to 45°, turn the 45° bevel angle adjusting bolt (upper bolt) on the right side of the arm until the pointer points to 45°.

Replacing carbon brushes
Remove and check the carbon brushes regularly. Replace them 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. After replacing the brushes, insert the battery cartridge into the tool and break in the brushes by running the tool with no load for about 1 minute. Then check the tool while running and the electric brake operation when releasing the switch trigger. If the electric brake is not working well, ask your local Makita service centre for repair.
