Inspect all electrical cords regularly. Never use in or near water or in any environment where electric shock is possible.

DOUBLE INSULATION FOR SAFER OPERATION

To ensure safer operation of this power tool, HITACHI has adopted a double insulation design. “Double insulation” means that two physically separated insulation systems have been used to insulate the electrically conductive materials connected to the power supply from the outer frame handled by the operator.Therefore, either the symbol “ ” or the words and “Double insulation” appear on the power tool or on the nameplate. Although this system has no external grounding, you must still follow the normal electrical safety precautions given in this Instruction Manual, including not using the power tool in wet environments.

To keep the double insulation system effective, follow these precautions:

*Only HITACHI AUTHORIZED SERVICE CENTER should disassemble or assemble this power tool, and only genuine HITACHI replacement parts should be installed.

*Clean the exterior of the power tool only with a soft cloth moistened with soapy water and dry thoroughly.

*Never use solvents, gasoline or thinners on plastic components; otherwise the plastic may dissolve.

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, if the table insert is fixed so that the gap between the 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

Loosen the three 6mm machine screws, then secure the left side table insert and temporarily tighten the 6mm machine screws of both ends. Then fix a workpiece (about 7-7/8" (200mm) wide) with the vise assembly and cut it off. After aligning the cutting surface with the edge of the table insert, securely tighten the 6mm machine screws of both ends. Remove the workpiece and securely tighten the 6mm center machine screw. Adjust the right hand table insert in the same way.

(2)Left and right bevel angle cutting

Adjust the table insert in the manner shown in Fig. 9 following the same procedure for right angle cutting.

CAUTION: After adjusting the table insert for right angle cutting, the table insert will be cut to some extent if it is used for bevel angle cutting.

When bevel cutting operation is required, adjust the table insert for bevel angle cutting.

Fig. 18

The vise assembly can be mounted on either the left fence {Fence (B)} or the right fence {Fence (A)}, and can be raised or lowered according to the height of the workpiece.

To raise or lower the vise assembly, first loosen the 10mm knob bolt. As shown in Fig. 18, the vise shaft has four locking grooves into which the tip of the 10mm knob bolt is designed to fit in order to lock the screw holder in the desired position.

To ensure that the tip of the 10mm knob bolt is properly aligned with the desired locking groove on the vise shaft, simply align the upper surface of the fence to either of three grooves on the vise shaft surface or to the lower surface of the screw holder.

Therefore, the vise assembly can be attached in either of four positions to ensure proper height adjustment.

After adjusting the height, firmly tighten the 10mm knob bolt; then turn the upper knob, as necessary, to securely attach the workpiece in position.

CAUTION: Always confirm 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 10mm knob bolt slightly and move the vise to a position where it will not contact the saw blade.

Also, always confirm that the vise assembly is mounted on the right side {Fence (A)} before using the saw for compound cutting operations (miter + bevel cutting).

(1)As shown in Fig. 21 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 to the left when length a is desired.

(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.

(4)After cutting the workpiece to the desired depth, turn the power tool OFF and let the saw blade stop completely before raising the handle from the workpiece to return it to the full retract position.

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 efficiency.

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 remove the lock-off button from the handle and store it in a secure place after completing the work.

Then press down on the handle and slide the saw blade back to cut the workpiece as indicated in Fig. 23. This facilitates cutting of workpieces of up to 3-11/32" (85mm) in height and 12-9/32" (312mm) in width.

(2)Workpieces up to 3-35/64" (90mm) high and 11-39/64" (295mm) wide: Workpieces of up to 3-35/64" (90mm) in height and up to 11-39/64" (295mm) in width can be cut in the same manner as described in paragraph 6-(1) above.

Fig. 23

CAUTION:

WARNING:

*When cutting a workpiece of 3-35/64" (90mm) 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 3mm) 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.

*For slide cutting, follow the procedures indicated above in Fig. 23.

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.

(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 fixing pin towards the rear.

(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 5 and 6 above. For maximum dimensions for bevel cutting, refer to “SPECIFICATIONS” table on page 9.

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 safety cover to be caught in the cutting groove of the workpiece and to contact the saw blade.

CAUTION: When cutting a workpiece of 2-3/8" (60mm) height in the left 45° bevel cutting position or a workpiece of 1-3/8" (35mm) 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 3mm) at the lower limit position (refer to “3. Checking the saw blade lower limit position” on page 14).

(1)Loosen the side handle and adjust the turntable until the indicator aligns with the desired setting on the miter scale (Fig. 27).

(2)Re-tighten the side handle to secure the turntable in the desired position.

(3)The miter scale (Fig. 25) 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. 26).

(5)Therefore, to cut a workpiece at a grade of 2/10, set the indicator to position a as indicated in Fig. 25.

NOTE: * Positive stops are provided at the right and left of the 0° center setting, at 15°, 22.5°, 31.6°, 35.3° 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.

English

9. Compound cutting procedures

Compound cutting can be performed by following the instructions in 7 and 8 above. For maximum dimensions for compound cutting, refer to “SPECIFICATIONS” table on page 9.

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.

10. Crown molding cutting procedures

(3) Lift the safety cover and mount the saw blade.

WARNING: When mounting the saw blade, confirm that the rotation indicator mark on the saw blade and the rotation direction of the side cover (L) (see Fig. 1) are properly matched.

(4)Thoroughly clean washer (C) and the bolt, and install them onto the saw blade spindle.

(5)Press in the spindle lock and tighten the bolt by turning it to the left by 10mm box wrench as indicated in Fig. 42-b.

CAUTION: * A dust guide is installed inside behind the side cover (L).

When removing or installing the saw blade, do not make contact with the dust guide. Contact may break or chip saw blade tips.

*Confirm that the spindle lock has returned to the retract position after installing or removing the saw blade.

*Tighten the bolt so it does not come loose during operation.

Confirm the bolt has been properly tightened before the power tool is started.

2.Dismounting the saw blade

Dismount the saw blade by reversing the mounting procedures described in paragraph 1 above. The saw blade can easily be removed after lifting the safety cover.

CAUTION: Never attempt to install saw blades larger than 10" (255mm) in diameter. Always install saw blades that are 10" (255mm) in diameter or less.

OVERLOAD PROTECTIVE DEVICE FOR POLY-V-BELT

The power of the motor is transmitted to the saw blade by a Poly-V-Belt. When the Poly-V-Belt becomes overloaded, the overload protective device cuts off the current to stop the motor.

In this case turn the switch off immediately and raise the handle to its initial position. Then turn the switch on and after running the tool for 20 seconds without a load for cooling of the motor. Then start the cutting operation.The Poly-V-Belt or the motor will be damaged if the overload protective device turns off frequently.

CAUTION: When the overload protective device stops the motor, the motor will start by turning the switch on after turning it off. When turning the switch on, make sure that the saw blade is not halfway in the material.

MAINTENANCE AND INSPECTION

WARNING: To avoid an accident or personal injury, always confirm 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 first sign of deterioration or damage.

A damaged saw blade can cause personal injury and a worn saw blade can cause ineffective 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.

2. Adjusting a loose slide pipe

8mm Hex. Socket

8mm Nut

Bushing

Head Screw

Slide Pipe (A)

Holder (A)

After extended use of the power tool, the slide pipe (A) and the bushing can become loose due to vibration. Never operate the tool if any components are loose to avoid personal injury.

(1)Loosen the 8mm nut and tighten the four 8mm hexagon socket set screws until the power tool operates smoothly without looseness.

(2)Properly tighten the 8mm nut after completing these adjustment.

3. Inspecting the carbon brushes (Fig. 44 and Fig. 45)

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. 44.

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. 45) with a slotted (minus) screwdriver.
