Fast cutting speed thanks to high-power motor

The Model CR 13V2 can cut various types of construction materials fast and efficiently thanks to a high-

power motor with more than 1000 W of maximum output.

Speed selectable switch trigger

The Model CR 13V2 is equipped with an electronic control circuit for steplessly adjusting cutting speed by

means of a switch trigger, depending on the work conditions and type of workpiece.

Tool-less blade detachable mechanism (Same as Model CR 13VBY)

Recently, most saber saws on the market are coming

equipped with a mechanism that requires no hexagonal

wrench or other tool for mounting and removing saw blades.

The Model CR 13V2 is also equipped with such a mechanism

that enables speedy blade replacement.

Simply pressing a lever to easily mount or remove the saw

blade.

Saw blade mountable in either up or down direction

The Model CR 13V2 is convenient for cutting materials on the floor or near a wall, and also for plunge

cutting on plywood panels since the saw blade can be inversely mounted into position.

Dust-and water-resistant triple-sealing construction

The Model CR 13V2 has a triple-sealing construction that protects against large amounts of dust generated

from the cutting of construction materials such as autoclaved lightweight concrete panels, and also seals

out waste water during pipe-cutting work.

Conventional high-speed steel blades tend to break easily in such heavy applications as house

demolition work. To cope with this problem, the bimetal blades listed in the table below are provided as

optional accessories. These bimetal blades are tough and rarely break thanks to two different types of

steel combined via electron-beam welding. A very hard steel called "DM05" (JIS SKH51 or equivalent

molybdenum containing high-speed steel) or "Matrix II" (JIS SKH56 or equivalent cobalt containing

high-speed steel) is used along the cutting edges, with flexible spring steel used for the main blade body.

As a result, the bimetal blades are significantly stronger than conventional high-speed steel blades.

Reassembly can be accomplished by following the disassembly procedures in reverse. However,

particular attention should be given to the following items.

1. Mounting the Recipro Plate (F) assembly on the Second Shaft (F) (Fig. 11)

For press-fitting, use the dedicated jig (J-315). First, form the Recipro Plate (F) [28] assembly by attaching

the two Ball Bearings 6003VVCM (Nylon Retainer) [29] and Retaining Ring For D35 Hole [30] to the

Recipro Plate (F) [28].

(a) With the Gear (F) [32] and Ball Bearing 608VVC2PS2L [33] not incorporated

As shown in Fig. 11-a, mount the Recipro Plate (F) [28] assembly and the Second Shaft (F) [31] on the

jig, and then use a press to push in the direction of the arrow.

(b) With the Gear (F) [32] and Ball Bearing 608VVC2PS2L [33] incorporated

As shown in Fig. 11-b, mount the Recipro Plate (F) [28] assembly and the Second Shaft (F) [31] on the

jig, and then use a press to push in the direction of the arrow.

When press-fitting the Recipro Plate (F) [28] assembly, be sure to apply pressure in the correct

direction.

two Swing Rollers [14], and then incorporate these parts into the Plunger (F) [12]. Next, apply Nippeco

SEP-3A to the polished portion of the Plunger (F) [12], and then insert the Plunger (F) [12] into the Gear

Cover (F) [4]. Here, insert the Plunger (F) [12] while slowly rotating it both clockwise and counterclockwise

to avoid damaging the Felt Washer [6], V-Ring [8], and O-Ring [9]. Please remember that the Felt Washer

[6] can be inadvertently pulled out by the Plunger (F) [12].

5. Reassembling the Blade Mount (Figs. 15 to 19)

First, insert the Spring (B) [20] and Holder Pin (B) [19] into the Plunger (F) [12]. Apply Nippeco SEP-3A to

the sloped portion of the Lever (C) [22], incorporate the shorter leg of the Blade Spring [23] into the Lever

accomplished by using your finger to push the longer leg of the Blade Spring [23] into the Lever (C) [22]

(see Fig. 15), while tilting the Blade Spring [23]) inside the Blade Holder (C) [5] as shown in Fig. 15. With

the resulting state being maintained as shown in Fig. 16, insert the Blade Holder (C) [5] from the leading

end of the Plunger (F) [12].

Make adjustments until the bolt hole on the Blade Holder (C) [5] becomes visible from the hole on the Lever

Nut M5 [11] at the specified torque. Here, be careful not to excessively tighten the Special Bolt M5 [21] and

Lock Nut M5 [11]; otherwise, the Lever (C) [22] will be damaged. Press the rubber Cap [18] laterally

against the Lever (C) [22] in the downward arrow direction, confirm that there is no gap between the Cap

[18] and Blade Holder (C) [5], and then properly reassemble the blade mount. Finally, mount and demount

a blade in order to check the blade mount for any abnormalities.
