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.

Use a flat-blade screwdriver or similar tool to remove the Nylock Bolt (W/Flange) M5 x 12 [15], Base (F) [1],
and Cover Pin [3], and then pull the Front Cover (F) [2] away from the main body.
2. Disassembling the Gear Cover (F) (Figs. 2 and 4) and blade mount (Fig. 3)
With the armature assembly fan secured, loosen the Nylock Bolt (W/Flange) M6 x 35 [16] beforehand
(about two turns). Remove the four Machine Screws (W/Washers) M5 x 60 (Black) [47], and then remove
the Gear Cover (F) [4] from the main body. Remove the Nylock Bolt (W/Flange) M6 x 35 [16] and Washer

3. Disassembling the Second Shaft (F) (Fig. 5)
First, remove the Ball Bearing 608VVC2PS2L [33] from the Second Shaft (F) [31]. With a lateral surface of
the Gear (F) [32] being received, use a press to push the end face of the Second Shaft (F) [31] and remove
the Gear (F) [32] from the Second Shaft (F) [31]. Then remove the Retaining Ring For D17 Shaft [27] from
the Second Shaft (F) [31]. With a lateral surface of the Recipro Plate (F) [28] being received, use a press to
push the end face of the Second Shaft (F) [31] (i.e., surface parallel to lateral surface of the Recipro Plate
(F) [28]) and remove the Recipro Plate (F) [28] as one assembly. Finally, remove the Retaining Ring For

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.

2. Mounting the Metal (B) on the Gear Cover (F) (Fig. 12)
First, apply Nippeco SEP-3A to the inner periphery of the Metal (B) [10] and O-Ring [9], and then fit the
O-Ring [9] into the internal groove of the Metal (B) [10].
Insert the Felt Washer [6], Washer (H) [7], and V-Ring [8] into the Gear Cover (F) [4] in this order. Then
press-fit the Metal (B) [10] until striking bottom. (Note that one end of the Metal (B) [10] is provided with an
inspection hole.) It is very important to insert the Felt Washer [6], Washer (H) [7], and V-Ring [8]
individually into the specified positions on the Gear Cover (F) [4]. If these parts are not properly inserted
into position, press-fitting the Metal (B) [10] may cause parts to break, Plunger (F) [12] mounting failure,
and impaired dustproofness or waterproofness.
Also ensure that the V-Ring [8] is properly oriented when inserted.
3. Mounting the Ball Bearing 6002DDMPS2L on the Gear Cover (F) (Fig. 13)
When mounting the Ball Bearing 6002DDCMPS2L [24] on the Gear Cover (F) [4], ensure that the Ball
Bearing 6002DDCMPS2L [24] abuts on the Gear Cover (F) [4]. Also tighten all three Nylock Bolts
(W/Flange) M4 x 12 [25] two times at the specified torque.
The product may be damaged if the Ball Bearing 6002DDCMPS2L [24] is improperly mounted or the
Nylock Bolts (W/Flange) M4 x 12 [25] are improperly tightened.

4. Mounting the Plunger (F) on the Gear Cover (F) (Fig. 14)
Apply Nippeco SEP-3A to the outer periphery of the Connector Pin (F) [13] and the inner periphery of the
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
(C) [22], and then incorporate the Lever (C) [22] into the Blade Holder (C) [5]. This step can be easily
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
(C) [22], insert the Special Bolt M5 [21] into position, and then tighten the Special Bolt M5 [21] and Lock
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.
