1. PRODUCT NAME Hitachi 130 mm (5") Reciprocating Saw, Model CR 13VA 2. MARKETING OBJECTIVE There is increasing demand for a high-speed and powerful saber saw in overseas markets. The new Model CR 13VA, which features a powerful motor and a swing cutting action, has been developed to meet that market demand. The swing cutting action is a new technology, in which the saw blade is swung like a pendulum, regardless of whether the saw blade is mounted upward or downward.
-1. Selling Point Descriptions (1) Fast cutting speed The Model CR 13VA can cut various construction materials fast and efficiently thanks to the high-power motor whose maximum output is over 1000 W (Model CR 10V: 680 V). (2) Saw blade can be mounted and removed without the use of tools (patent pending) Generally, conventional saber saws required a blade holder and a bolt to secure the saw blade.
(3) Saw blade can be mounted in either direction, upward or downward The Model CR 13VA is convenient for cutting materials on the floor or near window frames, and also for plunge cutting on plywood panels because the saw blade can be installed upside down. < Cutting on the floor in two-by-four construction > < Plunge cutting on plywood panels > (4) New swing cutting action (patent pending) Two cutting systems, smooth "straight cutting" and efficient "swing cutting", can be selected with the change lever.
(5) Dust- and water-resistant triple-sealing construction The Model CR 13VA has a triple-sealing construction to protect from the large amount of dust generated when cutting construction materials, autoclaved lightweight concrete, etc. and also from waste water when cutting pipes. 1 Dust-resistant felt ring (with backup ring) It prevents dust from entering by way of the plunger (reciprocating shaft).

5-2. Optional Accessories The cutting speed of the Model CR 13VA is substantially higher than that of the current model, however, the conventional HCS blades may be broken in heavy applications such as house demolition, etc. To cope with this problem, the BI-METAL blades shown in Table 2 are provided. The BI-METAL blades are tough and rarely break since they are made by electron-beam welding together of two different types of steels.
(2) BI-METAL blades The blade numbers of BI-METAL blades in Table 2 are engraved in the vicinity of the mounting position of each blade. Select appropriate blades by referring to Table 2 and 3 below.

8. PRECAUTIONS IN SALES PROMOTION In the interest of promoting the safest and most efficient use of the Model CR 13VA Reciprocating Saw by all of our customers, it is very important that at the time of sale, the salesperson carefully ensures that the buyer seriously recognizes the importance of the contents of the Handling Instructions, and fully understands the meaning of the precautions listed on the Name Plate attached to each tool. 8-1.
9. REPAIR GUIDE 9-1. PRECAUTIONS IN DISASSEMBLY AND REASSEMBLY Please follow the precautions below for disassembly and reassembly procedures. The circled numbers in the following figures and the [Bold] numbers in the descriptions below correspond to the item numbers in the Parts List. Prior to attempting disassembly or replacement of the saw blade, ensure that the power cord plug is disconnected from the power source. 1. Disassembly (1) Disassembly of Front Covers (A) and (B) [46] [26] section (Fig.
Loosen the Nylock Bolt (W/Flange) M6 x 35 [47] which secures the fan of the armature ass'y (approximately two turns). Remove the four Machine Screws (W/Washers) M5 x 60 [42] and then pull out the Gear Cover [31] from the main body. Remove the Nylock Bolt (W/Flange) M6 x 35 [47], then Second Shaft (A) [64] section and the Sub Shaft [57] can be removed from the Gear Cover [31].
(3) Disassembly of the blade mounting section (Fig. 5) Remove the Retaining Ring (E-Type) for D14 Shaft [2] from Plunger (A) Set [32] with a flatblade screwdriver. At this time, be careful that Spring (A) [19] is pushing against the retaining ring. Next, slide the Guide Washer [17] backward and remove the two Steel Balls D4.76 [15]. Move Holder Sleeve (B) [14] backward and adjust the position of the notch on Holder Sleeve (B) [14] (see Fig.
(5) Disassembly of the Second Shaft (A) [64] section (Fig. 7) Remove the Retaining Ring for D17 Shaft [60] from Second Shaft (A) [64]. While holding the side surface of the Recipro Plate [61], push the end surface of Second Shaft (A) [64] (parallel with the side surface of the Recipro Plate [61]) with a hand press and remove the Recipro Plate [61] in an assembled state.
(8) Disassembly of Handles (A) [74] and (B) [80] section (Fig. 10) Remove the six Tapping Screws (W/Flange) D4 x 25 [43]. Remove the Grip Cover [81] by pulling it backward and remove Handle (A) [74]. Then, the Switch Trigger [76] can be removed. 80 81 Fig. 10 (9) Disassembly of Handle (B) [80] and the Switch [75] section (Fig. 11) Disconnect the two internal wires coming from the Stator [73] and the two internal wires coming from the Cord [85] by loosening the small screw on the switch.
2. Reassembly Reassembly can be accomplished by following the disassembly procedures in reverse. However, special attention should be given to following items. (1) Press-fitting the Recipro Plate [61] ass'y into Second Shaft (A) [64] (Fig.13) Tool required: Special repair tool J-315 Mount the two Ball Bearings 6003VVCMPS2L [62] and the Retaining Ring for D35 Hole [63] to the Recipro Plate [61] to complete the assembly (recipro plate ass'y).
(3) Reassembly of the blade mounting section (Figs. 15, 16 and 17) Apply Doubrex 251 grease to the inner circumference of Holder Sleeve (B) [14] and the cam groove of Plunger (A) Set [32]. Mount Washer (E) [1], Thrust Bearing [21], Washer (D) [20], Spring (A) [19], Dust Washer [18], Guide Washer [17], Holder Sleeve (C) [16], Holder Sleeve (B) [14] and Holder Sleeve (A) [13] in the Plunger (A) Set [32] through the tip in order (Fig. 15).
(4) Press-fitting plunger (A) into the plunger sleeve (Figs. 18 and 19) Tool required: Special repair tool J-317 Apply Nippeco SEP-3A grease to the sliding portion of plunger (A) and insert it into the Guide Sleeve Ass'y [9]. Insert the Pin D6 [54] into plunger (A). Mount it to the special repair tool J-317 and press-fit it in the direction of the arrow as shown in Fig. 18. At this time, be careful not to gall the plunger sleeve. After reassembly, check that plunger (A) slides smoothly.
* Be careful not to damage Washer (F) [3]. (Fig. 21) Washer (F) has an oval shape to fit the inside of the Gear Cover [31]. Therefore, perform disassembly and reassembly so that washer (F) is properly aligned with the shape of the gear cover. Fig. 21 *Be careful of the direction of the Cord Clip [78]. (Fig. 22) Cord dia.: More than 6.4 mm, 8.5 mm or less Cord dia.: More than 8.5 mm, 10.8 mm or less Fig.
