SAFETY INSTRUCTIONS FOR MITER SAW

Miter 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 dlist causes moving parts such as the lower guard to jam. Sparks from abrasive cutting will burn the Tower guard, the kerf insert and other plasic parts.
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 bide contact.
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 “freshand” in any way.
Unrestrained or moving workpieces could be thrown at high’speeds, causing injury.
Pushthe 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.
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 s very dangerous.
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 biade to your hand may not be obvious and you may be seriotsly injured.
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 waiped workpieces can twist or shift and may cause binding on tile spinning saw bladee while cutting.
There should be no nails or foreign objects in the workpiece.
Donot use the saw until the table is clear of all tools, wood scraps, etc., except for the workpiece.
Small debris or loose pieces of wood or other objects that contact the revolving blade can be thrown with high speed.
Cutonly one workpiece at a time.
Stacked multiple workpieces cannot be adequately clamped o braced and may bind on the blade or shitt during cutting.
Ensure the miter saw is mounted or placed ona level, firm work surface before use.
Alevel and firm work surface reduces the risk of the ‘miter saw becoming unstable.
Plan your work. Every time you change the bevel or miter angle setting, make sure the adjustable fence is set correctly to support the workpiece and will not interfere with the biade 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.
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 miter saw table cantip if not securely supported. f the cut-off piece or workpiece tips, it can it the lower guard or be thrown by the spinning blade.
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 0 bind or the workpiece to shift during the cutting ‘operation puling you and the helper into the spinning blade.
The cut-off piece must not be jammed o 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.
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 puil the work with your hand into the biade.
Let the blade reach full speed before contacting the workpiece.
This will reduce the risk of the workpiece being thrown.
If the workpiece o blade becomes jammed, tum the miter 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 lass of control or damage to the miter saw.
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.
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 t0 be suddenly pulled downward, causing a risk of injury.

PRECAUTIONS ON USING SLIDE COMPOUND MITER SAW

Keep the floor area around the machine level. Well maintained and free of loose materials e.g. chips and cut-offs.
Provide adequate general or localized lighting.
Do not use power tools for applications other than those specified in the handling instructions.
Repairing must be done only by authorized service facility. Manufacturer is not responsible for any damages and injuries due to the repair by the unauthorized persons as well as the mishandling of the tool.
To ensure the designed operational integrity of power toals, do not remove installed covers or screws.
Do not touch movable parts or accessories unless the power source has been disconnected.
Use your tool at lower input than specified on the nameplate; otherwise, the finish may be spoiled and working efficiency reduced due to motor overload.
Do not wipe plastic parts with solvent. Solvents such as gasoline, thinner, benzine, carbon tetrachloride, alcohol, may damage and crack plastic parts. Do not wipe them with such solvent. Clean plastic parts with a soft cloth lightly dampened with soapy water.
Use only original HiKOKI replacement parts.
This tool should only be disassembled for replacement of carbon brushes.
Never cut ferrous metals or masonry.
Adequate general or localized lighting is provided. Stock and finished workpieces are located close to the operators normal working position.
Wear suitable personal protective equipment when necessary, this could include: Hearing protection to reduce the risk of induced hearing loss.
Eye protection to reduce the risk of injuring an eye.
Respiratory protection to reduce the risk of inhalation of harmful dust.
Gloves for handling saw blades (saw blades shall be carried in a holder wherever practicable) and rough material.
The operator is adequately trained in the use, adjustment and operation of the machine.
Refrain from removing any cut-offs or other parts of the workpiece from the cutting area whilst the machine is running and the saw head is not in the rest position.
Never use the slide compound miter saw with its lower guard locked in the open position.
Ensure that the lower guard moves smoothly.
Do not use the saw without guards in position, in good working order and properly maintained.
Use correctly sharpened saw blades. Observe the maximum speed marked on the saw blade.
Do not use saw blades which are damaged or deformed.
Do not use saw blades manufactured from high speed steel.
Use only saw blades recommended by HIKOKI.
The saw blades should be 305 mm external diameter.
Select the correct saw blade for the materialto be cu.
Never operate the slide compound miter saw with the saw blade turned upward or to the side.
Ensure that the workpiece is free of foreign matter such as nails.
Replace the table insert when worn.
Do not use the saw to cut other than aluminium, wood or similar materials.
Do not use the saw to cut other materials than those recommended by the manufacturer.
Blade replacement procedure, including the method for repositioning and a warning that this must be carried out correctly.
Connect the slide compound miter saw to a dust collecting device when sawing wood.
Take care when slotting.
When transporting or carrying the tool, do not grasp the holder. Grasp the handle instead of the holder.
Start cutting only after motor revolution reaches maximum speed.
Promptly cut OFF the switch when abnormality observed.
Shut off power and wait for saw blade to stop before servicing or adjusting tool.
During a miter or bevel cut the blade should not be lifted until it has stopped rotation completely.
During slide cutting operation, the saw must be pushed and slided away from the operator.
Take all the possibility of residual risks in cutting operation into your consideration, such as the inadvertent access to moving parts on slide mechanical parts on machine and so on.
Ensure before each cut that the machine is stable.
Do not stand in a line with the saw blade In front of the machine. Always stand aside of the saw blade. This protects your body against possible kickback. Keep hands, fingers and arms away from the rotating saw blade.
Do not cross your arms when operating the tool arm.
If the saw blade should become jammed, switch the machine off and hold the workpiece until the saw blade comes to a complete stop. To prevent kickback, the workpiece may not be moved until after the machine has come to a complete stop.
Correct the cause for the jamming of the saw blade before restarting the machine.
When the saw head is in the down position, never release the hand that is gripping the handle.
Doing so could snap the saw head up, forcing the tool to fall and possibly cause injury.
Make sure to securely hold the tool during operation.
Failure to do so can result in accidents or injuries. (Fig. 2)
Do not look directly into the light. Such actions could result in eye injury.
Wipe off any dirt or grime attached to the lens of the LED light with a soft cloth, being careful not to scratch the lens.
Scratches on the lens of the LED light can result in decreased brightness.

NOTE
Confirm that the saw blade is adjusted so that it will not cutinto the turntable.

PRIOR TO CUTTING

Positioning the table insert (Fig. 10)
Table inserts are installed on the turntable. When shipping the tool from the factory, the table inserts are so fixed that the saw blade does not contact them. The burr of the bottom surface of the workpiece is remarkably reduced, i the table insert is fixed sothat the gap betweenthe side surface of the table insert and the saw blade will be minimum. Before using the tool, eliminate this gap in accordance with the following procedure.
(1) Right angle cutting
Loosenthe three 5 mm machine screws, then secure the left side table insert and temporarily ighten the 5 mm machine screws of both ends. Then fix a workpiece (about 200 mm wide) with the vise assembly and cut it off. After aligning the cutting surface with the edge of the table insert, securely tighten the 5mm machine screws of both ends. Remove the workpiece: and securely tighten the 5 mm center machine screw.
Adjust the right hand table insert in the same way.
(2) Left andright bevel angle cutting
Adjust the table insertin the manner same procedure forright angle cutting.
CAUTION
After adjusting the table insert for right angle cutting, the table insertwill be cut to some extent i it is used for bevelangle cutting.
When bevel cutting operation is required, adjust the table insert for bevel angle cutting.
Confirmation for use of sub fence (A) (Fig. 11)
WARNING
When right bevel angle cutting, loosen the 6 mmwing bolt, then slide the sub fence (A) outward and remove it
Faillre to do so may resultin the main body or saw blade coming into contact with the sub fence (4) and causing injury.
This power tool is equipped with a sub fence (A). In the case of direct angle cutting and left bevel angle cutting, use the sub fence (A). Then, you can realize stable cutting of the material with a wide back face.
CAUTION
In the case of direct angle cutting and left bevel angle cutting, slide inward to the position where the sub fence (A) hits, and secure itwith 6 mmwing bolt. (as shown in Fig. 1)
Confirmation for use of sub fence (B) (Fig. 12)
WARNING
When left bevel angle cutting, loosen the & mm wing bolt, then slide the sub fence (B) outward. Failureto do S0 may result in the main body or saw blade coming into contact with the sub fence (B) and causing injury.
This power tool is equipped with a sub fence (B). In the case of direct angle cutting and right bevel angle cutting, use the sub fence (B). Then, you can realize stable cutting of the material with a wide back face.
CAUTION
In the case of direct angle cutting and right bevel angle cutting, slide inward to the position where the sub fence (B) hits, and secure itwith 6 mmwing bolt. (as shown in Fig. 12)
Slide carriage system (Fig. 13)
WARNING
To reduce the fisk of injury, retum slide carriage tothe ullrear position after each crosscut operation.
For chop cutiing operations on small workpieces, siide the cutting head assembly completely toward the rear of the unit and tighten the siide securing knob. To cut wide boards up to 312 mm, the slide securing knob must be loosened to allow the cutting head slide freely.
Miter scale adjustment
Down the head and insert the locking pin.
Unlock the miter lock handle and swing the turntable until the positive stop locks it at the 0° miter position.
Do not lock the miter lock handle. Place a square against the saw’s fence and blade, as shown in Fig. 14.
(Do not touch the tips of the blade teeth with the square.
To do so will cause an inaccurate measurement.)
If the saw blade is not exactly perpendicular to the fence, loosen the 6 mm machine screws (4 pcs.) that hold the miter scale and move the miter lock handle and the scaleleftor right until the blade is perpendicular to the fence, as measured with the square.
Retighten the 6 mm machine screws (4 pcs.). (Fig. 14) Pay no attention to the reading of the indicator (for miter scale) at this time.
Indicator (for miter scale) adjustment
Unlock the miter lock handle to move the tumtable to the 0° position. With the miter lock handle unlocked, allow the positive stop to snap into place as you rotate the turntable to 0°.
Observe the indicator (for miter scale) and miter scale as shown in Fig. 14. If the indicator (for miter scale) does not indicate exactly 0° loosen the 4 mm screw holding the indicator (for miter scale). In place reposition the indicator (for miter scale) and tighten the 4 mm screw.
Miter angle adjustment
The slide compound miter saw scale can be easily read, showing miter angles from 0° to 45° tothe leftand tight, The miter saw table has nine of the most common angle setttings with positive stops at 0°, 15°, 22.5°, 31.6°, and 45°. These positive stops position the blade at the desired angle quickly and accurately. Follow the process below for quickest and most accurate adjustments. (Fig. 15)
Adjusting miter angles:
(1) Pushup the miter lock handle to release the turntable.
(2) Push down the positive stop lever unti the detent lever catches on it o release the “positive stop”.
(3) Rotate the tuntable and set the indicator o line up with the desired angle of the miter scale. At this time, when using the positive stop function, puli the detent lever in the direction of the arrow near the desired angle as shown in Fig. 15, release the detent lever, and move via the positive stop function. (0%, 15°, 22.5°, 31.6%, and
(4) Push down the miter lock handle to secure the turntable in place.
Detent lever (Fig. 15)
The detent lever allows for the table to be micro adjusted, disengaging the positive detent stops feature. When a required miter angleis close to a positive detent stop, this detent lever prevents the wedge on the positive stop lever from slipping into that detent slot on the base.
LED lighting system (Fig. 16) [XACT CUT LED™] CAUTION
Do ot stare at operating lamp. Staring intothe light beam may resuiltin serious injury or vision loss.
The LED lighting system [XACT CUT LED™] casts the shadow of the blade onto the workpiece. This results in greater accuracy of cuts and requires no adjustments.
To use this feature, tum the LED light switch on.
Bring the motor head down so the blade is approximately 6 mm fromthe workpiece. The shadow of the blade will be projected onto the workpiece, indicating where the blade teeth will make contact as the cut is made.

Turn on the LED light
Press the LED light switch to switch the LED light.
Using the Vise Assembly (Standard accessory) (Fig. 19)
WARNING
Always firmly clamp or vise to secure the workpiece to the fence; otherwise the workpiece might be thrust from the table and cause bodily harm.
CAUTION
Always confirm that the motor head does not contact the vise assembly when it is lowered for cutting. If there is any danger that it may do so, move the vise assembly to a position where it will not contact the saw blade.
(1) The vise assembly can be mounted on the base.
(2) Turn the upper knob and securely fix the workpiece in position (Fig. 19).
NOTE
When using the vise, make sure that the tool is free of any excessive contact when the unit is swung or slid.
Cutting operation
(1) As shown in Fig. 20 the width of the saw blade is the width of the cut. Therefore, slide the workpiece to the right (viewed from the operator’s position) when length (b) is desired, or o the left when length @ is desired.
Turnthe LED light, project the shadow of the blade onto the workpiece, align the left side or right side of shadow of the blade withthe nk line on the workpiece.
(2) Afterturning on the switch and checking that the saw blade s rotating at maximum speed, slowly push down the handle and bring the saw biade in the vicinity of the material to be cut.
(3) Once the saw blade contacts the workpiece, push the handle down gradually to cut into the workpiece.
(4) After cutting the workpiece to the desired depth, tum the power tool OFF and let the saw blade stop completely before raising the handle from the workpiece to return itto the full retract position.
WARNING
Confirm that the trigger switch is turned OFF and the power plug has been removed from the receptacle.
whenever the tool is not in use.
Always turn the power off and let the saw blade stop completely before raising the handle from the workpiece. If the handle is raised while the saw blade is still rotating, the cut-off piece may become jammed against the saw blade causing fragments to scatter about dangerously.
Every time one cutting of deep-cutting operation is finished, turn the switch off, and check that the saw blade has stopped. Then raise the handle, and return it to the full retract position.
Be absolutely sure to remove the cut material from the top of the turntable, and then proceed to the next step.
Continued cutting operation can result in overload of the motor. Touch the motor and if it’s hot, stop your cutting operation at once and rest for 10 minutes or so, and then restart your cutting operation.
CAUTION
For maximum dimensions for cutting, refer to “SPECIFICATIONS?” table.
Increased pressure on the handle will not increase the cutting speed. On the contrary, too much pressure may result in overload of the motor and/or decreased cutting efficiency.
Cutting narrow workpieces (Press cutting) (Fig. 21)
Slide the hinge down to holder (A), then tighten the slide securing knob. Lower the handle to cut the workpiece.
Using the power tool this way will permit cutting of workpieces of up to 107 mm square.
Cutting large workpieces (Fig. 22)
There may be case when a complete cutting cannot be done depending on the height of workpiece. In this case, mount an auxiliary board with the 6 mm flat head screws and the 6 mm nuts using the 7 mm holes on the fence surface (two holes on each side). Refer to “SPECIFICATIONS?” for the thickness of the auxiliary board.
NOTE
When cutting a workpiece exceeding 107 mm in height in right-angle cutting or 70 mm in left bevel angle cutting or 45 mm in right bevel angle cutting, adjust the lower limit position so that the base of the motor head will not come in contact with the workpiece.
To adjustthe lower limit position of the saw blade, follow the procedure (1) shown in Fig. 23.
(1) Lower the motor head, and turn the 6 mm depth adjustment bolt and make adjustments so that there can be a clearance of 2 mm to 3 mm between the lower fimit position of the motor head and the top of the workpiece at the saw blade’s lower limit position where the head of the 6 mm depth adjustment bolt contacts the hinge.
Cutting wide workpieces (Slide cutting) (Fig. 24)
(1) Workpieces up to 107 mm high and 312 mm wide:
Loosen the slide securing knob, grip the handle and slide the saw blade forward. Then press down on the handle and slide the saw blade backward to cut the workpiece.
This facilitates cutting of workpieces of up to 107 mm in height and 312 mm in width.
(2) Workpieces up to 120 mm high and 260 mm wide:
Workpieces of up to 120 mm in height and up to 260 mm in width can be cut in the same manner as described in paragraph 6-(1) above.
WARNING
Forslide cutting, follow the procedures. Forward slide cutting (toward the operator) is very dangerous because the saw blade could kick upward from the workpiece. Therefore, always slide the handle away from the operator.
Always return the carriage to the full rear position after each crosscut operation in order to reduce the risk of injury.
Never put your hand on the miter lock handle during the cutting operation because the saw blade comes close to the miter lock handle when the motor head is lowered.
CAUTION
When cutting a workpiece of 120 mm height, adjust the lower limit position of the motor head so that the gap between the lower edge of the motor head and the workpiece will be 2 to 3 mm at the lower limit position.
If the handle is pressed down with excessive or lateral force, the saw blade may vibrate during the cutting operation and cause unwanted cutting marks on the workpiece, thus reducing the quality of the cut.
Accordingly, press the handle down gently and carefully.
Inslide cutting, gently push the handle back (rearwards) in a single, smooth operation. Stopping the handle movement during the cut will cause unwanted cutting marks on the workpiece.
Bevel cutting procedures (Fig. 25)
WARNING
When changing the oblique angle, hold down the motor head. If the motor head moves to an oblique angle sucdenly, it may result in injury or damage to the main body.
(1) Loosen the bevel lock handle and bevel the saw blade to the left or to the right.
To change the bevel angle to the right, loosen the bevel lock handle, then pull out the set pin (A) toward the front, and tilt the motor head to the right.
When the motor head is straight upright, the set pin (A) is held tightly in place, so tilt the motor head slightly to the left when pulling out the set pin (A) before tilting the motor head to the right.
(2) Adjustthe bevel angle to the desired setting while watching the bevel angle scale and indicator, then secure the bevel lock handle.
CAUTION
Always check thatthe bevellock handle is secured and the motor head is clamped. If you attempt angle cutting without clamping the motor head, then the motor head might shift unexpectedly causing injuries.
WARNING
When the workpiece is secured on the left o right side of the blade, the short cut-off portion will come to rest on the right or left side of the saw blade. Always tum the power off and let the saw blade stop completely before raising the handle from the workpiece.
lf the handleis raised while the saw blade is still rotating, the cut-off piece may become jammed against the saw blade causing fragments to scatter about dangerously. When stopping the bevel cutting operation halfway, start cutting after pulling back the motor head to the initial position.
Starting from halfway, without pulling back, causes the lower guard to be caught n the cutting groove of the workpiece and o contact the saw blade.
When right angle cutting, loosen the 6 mm wing bokt, then slide the sub fence (A) outward and remove it.
When left angle cutting, loosen the 6 mm wing bolf, then slide the sub fence (B) outward.
CAUTION
When cutting a workpiece of 75 mm height in the left 45° bevel cutting position or a workpiece of 50 mm heightin the right 45° bevel cutting position, adjust the lower limit position of the motor head so that the gap between the lower edge of the motor head and the workpiece will be 2 to 3 mm at the lower limit position (referto “11. Checking the saw blade lower limit position” on page 18).
NOTE
The bevel lock handle adopts a clutch system. When contacting the bevel lock handle and the main body, pull the bevellock handle inthe direction of the arow mark as illustrated in Fig. 25, and change the direction of the bevel lock handle.
