10. Position adjustment of laser line

WARNING: * Make sure before plugging the power plug into the receptacle

that the main body and the laser marker are turned off .

• Exercise utmost caution in handling a switch trigger for the position adjustment of the laser line, as the power plug is plugged into the receptacle during operation. If the switch trigger is pulled inadvertently, the saw blade can rotate and result in unexpected accidents.

• Do not remove the laser marker to be used for other purposes. CAUTION: Fig. 16 Fig. 15 C329113
• Laser radiation- Do not stare into beam.

• Laser radiation on work table. Do not stare into beam. If your eye is exposed directly to the laser beam, it can be hurt.

• Do not dismantle it. Holder (Optional accessory) Fig. 14 Workpiece 6 mm knob bolt (Optional accessory) Move Stopper (Optional accessory) 0000BookC12RSH2.indb210000BookC12RSH2.indb21 2017/08/3010:30:492017/08/3010:30:4922 English

• Do not give strong impact to the laser marker (main body of tool); otherwise, the position of a laser line can go out of order, resulting in the damage of the laser marker as well as a shortened service life.

• Keep the laser marker lit only during a cutting operation. Prolonged lighting of the laser marker can result in a shortened service life.

• Use of controls or adjustments or performance of procedures other than those specifi ed herein may result in hazardous radiation exposure. NOTE: * Perform cutting by overlapping the ink line with the laser line.

• When the ink line and the laser line are overlapped, the strength and weakness of light will change, resulting in a stable cutting operation because you can easily discern the conformity of lines. This ensures the minimum cutting errors.

• In outdoor or near-the-window operations, it may become diffi cult to observe the laser line due to the sunlight. Under such circumstances, move to a place that is not directly under the sunlight and engage in the operation.

• Do not tug on the cord behind the motor head or hook your fi nger, wood and the like around it; otherwise, the cord may come off and the laser marker may not be lit up. Ink lining can be easily made on this tool to the laser marker. A switch lights up the laser marker. (Fig. 17) Depending upon your cutting choice, the laser line can be aligned with the left side of the cutting width (saw blade) or the ink line on the right side. The laser line is adjusted to the width of the saw blade at the time of factory shipment. Adjust the positions of the saw blade and the laser line taking the following steps to suit the use of your choice. (1) Light up the laser marker and make a groove of about 3/16" (5 mm) deep on the workpiece that is about 25/32" (20 mm) in height and 5-29/32"(150 mm) in width. Hold the grooved workpiece by vise as it is and do not move it. For grooving work, refer to "13.Groove cutting procedures" on page 35. Fig. 17 Laser marker switch Laser line Saw blade Cutting width Fig. 18 Marking (pre-marked) Workpiece 0000BookC12RSH2.indb220000BookC12RSH2.indb22 2017/08/3010:30:492017/08/3010:30:4923 English (2) Then, turn the adjuster and shift the laser line. (If you turn the adjuster clockwise, the laser line will shift to the right and if you turn it counterclockwise, the laser line will shift to the left.) When you work with the ink line aligned with the left side of the saw blade, align the laser line with the left end of the groove. (Fig. 19) When you align it with the right side of the saw blade, align the laser line with the right side of the groove. (3) After adjusting the position of the laser line, draw a right-angle ink line on the workpiece and align the ink line with the laser line. When aligning the ink line, slide the workpiece little by little and secure it by vise at a position where the laser line overlaps with the ink line. Work on the grooving again and check the position of the laser line. If you wish to change the laser line’s position, make adjustments again following the steps from (1) to (3). NOTE: Check and make sure on a periodic basis if the position of the laser line is in order. As regards the checking method, draw a right-angle ink line on the workpiece with the height of about 25/32" (20 mm) and the width of 5-29/32"(150 mm), and check that the laser line is in line with the ink line [The deviation between the ink line and the laser line should be less than the ink line width (0.5 mm)]. (Fig. 20) PRACTICAL APPLICATIONS

2. Using the Vise Assembly (Standard accessory)

(1) The vise assembly can be mounted on the base. (2) Turn the upper knob and securely fi x the workpiece in position (Fig. 23).

WARNING: Always fi rmly 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 confi rm that the motor head (see Fig. 1) does not contact the vise assembly when it is lowered for cutting. If there is any danger that it may do so, loosen the Hex. socket set screw and move the vise assembly to a position where it will not contact the saw blade.

3. Cutting Operation

(1) As shown in Fig. 24 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 ⓑ is desired, or to the left when length ⓐ is desired. If a laser marker is used, align the laser line with the left side of the saw blade, and then align the ink line with the laser line. (2) Once the saw blade reaches maximum speed, push the handle down carefully until the saw blade approaches the workpiece. (3) Once the saw blade contacts the workpiece, push the handle down gradually to cut into the workpiece.

CAUTION: 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 effi ciency.

WARNING: * Confi rm 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 or deep-cutting operation is fi nished, turn the trigger 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 once and rest for 10 minutes or so, and then restart your cutting operation.

• Do not operate the head section or lift up the main unit while grasping the digital display (Fig. 1) as this could cause damage to the digital display.

4. Cutting narrow workpieces (Press cutting)

Slide the hinge down to holder (A), then tighten the slide securing knob (see Fig. 2) as indicated in Fig. 25 Lower the handle to cut the workpiece. Using the power tool this way will permit cutting of workpieces of up to 4-3/16" (107 mm) square. Fig. 25 Hinge Holder (A) Handle Press down Workpiece 0000BookC12RSH2.indb260000BookC12RSH2.indb26 2017/08/3010:30:492017/08/3010:30:4927 English

5. Cutting large workpieces

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 fl at head screws and the 6 mm nuts using the 7 mm holes on the fence surface (two holes on each side). (Fig. 26) Refer to page 12 "SPECIFICATIONS" for the thickness of the auxiliry board.

6. Cutting wide workpieces (Slide cutting)

(1) Workpieces up to 4-3/16" (107 mm) high and 12-1/4" (312 mm) wide: Loosen the slide securing knob (A) (see Fig. 2), grip the handle and slide the saw blade forward. Then press down on the handle and slide the saw blade back to cut the workpiece as indicated in Fig. 27. This facilitates cutting of workpieces of up to 4-3/16" (107 mm) in height and 12-1/4" (312 mm) in width. (2) Workpieces up to 4-11/16" (120 mm) high and 10-3/16" (260 mm) wide: Workpieces of up to 4-11/16" (120 mm) in height and up to 10-3/16" (260 mm) in width can be cut in the same manner as described in paragraph 6-(1) above. CAUTION: * When cutting a workpiece of 4-3/4" (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 5/64" to 1/8" (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.

• In slide 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.

WARNING: * For slide cutting, follow the procedures indicated above in Fig. 27.

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 side handle during the cutting operation because the saw blade comes close to the side handle when the motor head is lowered.

7. Bevel cutting procedures

(1) Loosen the clamp lever and bevel the saw blade to the left or to the right. When tilting the motor head to the right pull the set pin (A) towards the rear. The clamp lever adopts a latchet system. When contacting the work bench and the main body, pull the clamp lever in the direction of the arrow mark as illustrated in Fig. 28, and change the direction of the clamp lever. (2) Adjust the bevel angle to the desired setting while watching the bevel angle scale and indicator, then secure the clamp lever. (3) Follow the procedures indicated in paragraphs 4,5 and 6 above. For maximum dimensions for bevel cutting, refer to “SPECIFICATIONS” table on page 12.

WARNING: When the workpiece is secured on the left or 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 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. 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 in the cutting groove of the workpiece and to contact the saw blade. Set pin (A) Clamp Lever Bevel scale Fig. 28 Holder (A) Indicator (for right bevel scale) Pull 0000BookC12RSH2.indb280000BookC12RSH2.indb28 2017/08/3010:30:492017/08/3010:30:4929 English CAUTION: When cutting a workpiece of 2-15/16" (75 mm) height in the left 45° bevel cutting position or a workpiece of 1-15/16" (50 mm) height in 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 5/64" to 1/8" (2 to 3 mm) at the lower limit position (refer to “2. Checking the saw blade lower limit position” on page 18).

8. Bevel angle fi ne adjustment

(1) Grip the handle on the motor head and position it at the bevel angle you need. (2) After adjusting to the desired angle, tighten the clamp lever and clamp the motor head. CAUTION: * If not tightened fi rmly enough the motor head might suddenly move or slip, causing injuries. Be sure to tighten the motor head section enough so it will not move.

• Always check that the clamp lever 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.

9. Miter cutting procedures

(1) Loosen the side handle and pull up the lever for angle stoppers. Then, adjust the turntable until the indicator aligns with desired setting on the miter scale (Fig. 31). (2) Re-tighten the side handle to secure the turntable in the desired position. (3) The miter scale (Fig. 32) indicates both the cutting angle on the angle scale and the gradient on the grade scale. (4) The gradient, which is the ratio of the height to the base of the triangular section to be removed, may be used for setting the miter scale instead of the cutting angle, if desired (see Fig. 32). (5) Therefore, to cut a workpiece at a grade of 2/10, set the indicator to position ⓐ as indicated in Fig. 32. NOTE: * Positive stops are provided at the right and left of the 0° center setting, at 15°, 22.5°, 31.6° and 45° settings. Check that the miter scale and the tip of the indicator are properly aligned.

• Operation of the saw with the miter scale and indicator out of alignment, or with the side handle not properly tightened, will result in poor cutting precision.

10. Miter angle fi ne adjustment

(1) Rotate the turntable to the miter angle you need. (2) After adjusting to the desired angle, tighten the side handle. (Fig. 34.) CAUTION: Always check that the side handle is secured and the turntable is clamped. If you attempt angle cutting without clamping the turntable, then the turntable might shift unexpectedly causing injuries. Angle scale Grade scale

11. Compound cutting procedures

Compound cutting can be performed by following the instructions in 7 and 10 above. For maximum dimensions for compound cutting, refer to “SPECIFICATIONS” table on page 12. CAUTION: Always secure the workpiece with the right or left hand and cut it by sliding the round portion of the saw backwards with the left hand. It is very dangerous to rotate the turntable to the left during compound cutting because the saw blade may come into contact with the hand that is securing the workpiece. In case of compound cutting (angle + bevel) by left bevel, turn the sub-fence (B) counterclockwise, and engage in the cutting operation. In case of compound cutting (angle + bevel) by right bevel, turn the sub-fence (A) clockwise, and engage in the cutting operation.

12. Crown molding cutting procedures

Fig. 35 shows two common crown molding types having angles of (θ) 38° and 45°. For the typical crown molding fi ttings, see Fig. 36. Wall Ⓐ Upper surface ceiling Ⓑ Lower surface Fig. 35 Ceiling Wall

The table below shows the miter angle and the bevel angle settings that are ideal for the two crown molding types. NOTE: For convenience, positive stops are provided for the miter setting (left and right 31.6°) positions. For miter cut setting If the turntable has been set to either of the angles described, move the turntable adjusting side handle a little to the right and left to stabilize the position and to properly align the miter angle scale and the tip of the indicator before the operation starts. For bevel cut setting Turn the clamp lever on bevel section to the left and check that the position is stable and that the bevel angle scale and the tip of the indicator are properly aligned. Then tighten the clamp lever. 0000BookC12RSH2.indb310000BookC12RSH2.indb31 2017/08/3010:30:502017/08/3010:30:5032 English Type of Crown Molding To process crown molding at positions 1 and 4 in Fig. 36.

NOTE: When cutting a single groove at either end of the workpiece, remove the unneeded portion with a chisel.

14. Cutting easily-deformed materials, such as aluminum sash

Materials such as aluminum sash can easily deform when tightened too much in a vise assembly. This will cause ineffi cient cutting and possible overload of the motor. When cutting such materials, use a wood plate to protect the workpiece as shown in Fig. 48-a. Set the wood plate near the cutting section. When cutting aluminum materials, coat the saw blade with cutting oil (non-combustible) to achieve smooth cutting and a fi ne fi nish. In addition, in case of a U-shaped workpiece, use the wood plate as shown in Fig. 48-b to ensure stability in the lateral direction, and clamp it near the cutting section of the workpiece and tighten it using both the vise assembly and the clamp available in the market.

MAINTENANCE AND INSPECTION

WARNING: To avoid an accident or personal injury, always confi rm that

the trigger switch is turned OFF and the power plug has been disconnected from the receptacle before performing any maintenance or inspection of this tool.

1. Inspecting the saw blade

Always replace the saw blade immediately upon the fi rst sign of deterioration or damage. A damaged saw blade can cause personal injury and a worn saw blade can cause ineff ective operation and possible overload to the motor. CAUTION: Never use a dull saw blade. When a saw blade is dull, its resistance to the hand pressure applied by the tool handle tends to increase, making it unsafe to operate the power tool. 0000BookC12RSH2.indb380000BookC12RSH2.indb38 2017/08/3010:30:512017/08/3010:30:5139 English

2. Inspecting the carbon brushes (Fig. 51 and Fig. 52)

The carbon brushes in the motor are expendable parts. If the carbon brushes become excessively worn, motor trouble might occur. Therefore, inspect the carbon brushes periodically and replace them when they have become worn to the wear limit line as shown in Fig. 51. Also, keep the carbon brushes clean so that they will slide smoothly within the brush holders. The carbon brushes can easily be removed after removal of the brush caps (see Fig. 52) with a slotted (minus) screwdriver. NOTE: When replacing the carbon brushes, use only Hitachi carbon brushes having “38” in the last two digit of its Code No. (see Fig. 51). If you use other carbon brushes, the electric brake will not operate. 1/4" (6 mm) 11/16" (17 mm) No. 38 indicates the last two numbers of carbon brush Code No. Wear limit line

Winding of the motor is said to be the heart of this tool. Exercise utmost caution not to damage the winding by exposing it to wash oil or water. NOTE: Accumulation of dust and the like inside the motor can result in a malfunction. After using the motor for 50 hours or so, carry out no-load running, and blow in the dry air from a wind hole at the motor’s rear. Such action is eff ective to discharge dust and the like.

4. Inspecting the screws

Regularly inspect each component of the power tool for looseness. Re-tighten screws on any loose part.

WARNING: To prevent personal injury, never operate the power tool if any

components are loose.

5. Inspecting the lower guard for proper operation

Before each use of the tool, test the lower guard (see Fig. 7) to assure that it is in good condition and that it moves smoothly. Never use the tool unless the lower guard operates properly and it is in good mechanical condition. 0000BookC12RSH2.indb390000BookC12RSH2.indb39 2017/08/3010:30:512017/08/3010:30:5140 English

After operation of the tool has been completed, check that the following has been performed: (1) Trigger switch is in OFF position, (2) Power plug has been removed from the receptacle, When the tool is not in use, keep it stored in a dry place out of the reach of children.

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,

• Crystalline silica from bricks and cement and other masonry products, and

• Arsenic and chromium from chemically-treated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.
