1. PRODUCT NAME Hitachi Compound Saw, Model C 10FC2 2. MARKETING OBJECTIVE The Model C 10FC2 was developed to upgrade and replace the current Model C 10FC. The major difference between new model and current one is that the new model has a convenient miter angle setting mechanism for quick and easy. Only rotate the miter handle to clockwise which is equipped with the turn table, miter angle can be set (up to 60 right and 45 left). Of course, there are 10 positive miter stops: 0 , 15 , 22.5 , 31.

(1) Precautions on the Name Plate Each Model C 10FC2 is furnished with a Name Plate that lists the following precautions. CAUTION For safe operation, see instruction manual. Do not expose to rain or use in damp locations. Instruct the customer to thoroughly read the Instruction Manual prior to attempting to operate the machine. (2) Waring Label (A) The Warning Label (A) specified by the UL is affixed WARNING For Your Own Safety Read Instruction Manual Before Operating Miter Saw.
8. ADJUSTMENT AND OPERATIONAL PRECAUTIONS 8-1. Confirmation of Saw Blade Lower Limit Positioning 10 mm Depth adjustment screw The lower limit of the saw blade cutting depth is factory-adjusted so that when the saw blade is fully lowered, its cutting edge is 24 mm to 29 mm (1" to 1-1/8") below the upper surface of the 10 mm Lock nut table insert. Lower the saw blade and confirm that it stops at the correct position.
8-3. Cutting Operation (1) Cutting efficiency will be reduced if a dull saw blade is used, if an excessively long extension cord id used, or if the wire gauge of the extension cord is too small. (For details on extension cords, please refer to the Instruction Manual.) This is particularly important when cutting materials with dimensions which are at or near the maximum capacity for the machine.
(6) Compound (miter + bevel) cutting Compound cutting can be accomplished by combining the miter cutting and bevel cutting operations described in paragraphs (4) and (5) above. (For details, please refer to the Instruction Manual.) When the saw blade section (head) is inclined 45 to the left, the table can be turned up to 45 to the right and left.
9. ADJUSTMENT OF COMPONENTS 9-1. Bevel Angle Adjustment When shipped from the factory, the heights of 6 mm bolt (A) and 6 mm bolt (B) are adjusted so that the saw blade section (head) will stop at 0 (right-angle) and 45 to the left. To change the head stop positions, instruct the customer to adjust the height of 6 mm bolt (A) and 6 mm bolt (B) as described below. 6 mm Lock nut As illustrated in Fig. 10 and Fig.
11. PRECAUTIONS IN DISASSEMBLY AND REASSEMBLY 11-1. Disassembly Special attention in disassembly should be given to the following items.

11-2. Reassembly Reassembly can be accomplished by following the disassembly procedures in reverse. However, special attention should be given to following items. (1) Prior to reassembly, measure the insulation resistance of the armature, stator, switch and other electrical components and confirm that the insulation resistance of each part is more than 7 M . (2) When assembling the Angle Regulator [32] and the Arm [120], apply 2 grams of Hitachi Motor Grease to the oil groove of the Angle Regulator [32].
11-3. Wiring Diagram Carefully ensure that wiring is accomplished as illustrated below. As incorrect wiring will result in lack of rotation, reverse rotation or other malfunctions, close attention is absolutely necessary. 1 Wiring diagram 2PDT Black Blue (long) Field winding Red Blue (short) White Gray Brake winding White Fig.
11-5. No-load Current After no-load operation for 30 minutes, the no-load current values should be as follows. Voltage, Freauency 115 V, 60 Hz No-load current 7.4 A Max. 11-6.
(4) Reassembly of the Table [60] When reassembling the Table [60] and the Base [74], tighten the Chuck Nut M8 [58] so that the Table [60] turns smoothly without excessive play or vibration. During reassembly, liberally apply grease (Hitachi Motor Grease No. 29, Code No. 930035 is recommended.) at the point marked A in Fig. 23. Chuck Nut M8 [58] Table [60] A A Base [74] Center Shaft [75] Fig. 23 11-7. Lubrication Advise the customer to lubricate the machine as indicated below at least once a month.
12. REPAIR GUIDE Unit : mm Item 1 Phenomenon Inaccurate cutting ...Inaccurate spuareness of cut surface ...Cut surfaces do not fit together properly. Cause (s) Factory standard a Inaccurate squareness between the table and the saw blade causes the saw blade to cut into workpiece at an angle. 0.3/70 (Dummy disc) (Fig. 24) Adjust squareness with the Bolt M6 x 25 [54]. Adjust the Chuck Nut M16 [30] to eliminate looseness between the Arm [120] and the Angle Regulator [32].
Phenomenon Item 1 (Continued) Table Base Fig. 28 Cause (s) Factory standard g Excessive misalignment of the base and the table causes the saw blade to cut into the workpiece at an angle. 0.45 0 (Fig. 28) Replace the Base [74] and/ or Table [60] if deformed. h Loose fitting of swiveling portion of the arm and the angle regulator or sluggish movement. As a result, components may be deformed because of unstable arm or because the operator must apply excessive pressure during operation.
Item 2 Phenomenon (Continued) Cause (s) Factory standard Inspection • Repair • Adjustment d Excessively fast cutting speed --- Reduce cutting speed. e Improper clamping of workpiece --- Properly clamp workpiece with the Vise Ass'y [102]. f The table is not fixed with the handle bar. --- During cutting, fix the Table [60] in position with the Handle Bar [61] without fail. --- Same as the item 1- h . h Cutting operation becomes sluggish because workpiece is warped or bent.
Item 4 5 Factory standard Inspection • Repair • Adjustment a The power cord is not connected to power supply. --- Check power supply voltage. Connect the power cord to power supply. b The carbon brush wear exceeds allowable limit (6 mm) --- Chech the Carbon Brushes [135] for wear. Replace the Carbon Brushes [135]. c Contact failure of the switch. --- Check the Switch [91] for conductivity. Replace the Switch [91]. Saw blade runs too slow.
