1. PRODUCT NAME
Hitachi 130 mm (5") Reciprocating Saw, Model CR 13VC
2. MARKETING OBJECTIVE
The new Model CR 13VC is an upgraded version of the current Model CR 12V to satisfy the market demand for a
lightweight and high-speed saber saw. Thanks to the powerful motor, the Model CR 13VC offers the class-top
cutting performance. The weight is equivalent to that of the current Model CR 12V. The Model CR 13VC is easy
to operate and maintain thanks to the various convenient functions such as Hitachi-original tool-less blade
detachable mechanism.
3. APPLICATIONS
Cutting metal, wood and plastics etc.
4. SELLING POINTS
Saw blade can be
mounted in either upward
or downward direction
Fast cutting speed thanks to the high-power motor
[about 2 times faster than the current Model CR 12V]
Speed selectable dial scale and switch
trigger (same as the Model CR 13VA)
Dust- and water-resistant
triple-sealing construction
(same as the Model CR 13VA)
Nonskid and comfortable
soft grip handle
Easy-to-operate/maintain tool-less
blade detachable mechanism
(The Model CR 13VC is serviceable
without removing the front cover.)

--- 2 ---
4-1. 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 12V: 720 V).
(2) New tool-less blade detachable mechanism
Recently, most saber saws on the market are equipped with a mechanism that requires no tool such as
hexagonal wrench for mounting and removal of saw blades. The Model CR 13VC is also equipped with such
a mechanism in order to replace saw blades speedily.
[ Features of the tool-less blade detachable mechanism ]
Easy to mount and remove saw blades
Saw blades can be easily mounted and removed just by pressing the lever.
Easy to maintain
The tool-less blade detachable mechanism can be disassembled and reassembled without removing the
front cover.
<How to mount a saw blade>
(a) Push the lever in the direction of the arrow
mark marked on the lever.

(b) Insert the saw blade all the way into the small
slit of the plunger tip with the lever pushing.
(c) Release the lever and pull the back of the saw blade two or three times by hand to check that the
blade is securely mounted. When pulling the blade, you will know it is properly mounted if it clicks and
the lever moves slightly.

< Maintenance of the tool-less blade detachable mechanism >
After use, clean the blade mount with a brush to ensure that the tool-less blade detachable mechanism can
function smoothly. In addition to the regular maintenance, perform the following effective maintenance
occasionally.
Cleaning the inside of the tool-less blade detachable mechanism
Pull the rubber cap provided on the lever in the direction of an arrow mark shown below. Then the rubber
cap can be removed from the lever easily. Remove dust from the inside of the blade holder with air or the
like.

< Disassembly and cleaning of the tool-less blade detachable mechanism >
The tool-less blade detachable mechanism can be easily disassembled or reassembled because the fixing
bolt can be loosened or tightened without removing the front cover. To disassemble the tool-less blade
detachable mechanism, remove the fixing bolt and pull out the blade holder.
(Caution) This is a special bolt comprised of an M4 thread and an M5 hexagonal socket. Be careful not
to break the bolt by overtightening.
In case the saw blade is apt to come off
The saw blade is apt to come off if the blade hole is worn out. Replace the saw blade with new one. If the
new saw blade comes off even after replacement, the holder pin may be worn out. Replace the holder pin
with new one.

(3) Saw blade can be mounted in either direction, upward or downward
The Model CR 13VC is convenient for cutting materials on the floor or near the wall, and also for plunge
cutting on plywood panels because the saw blade can be mounted in reverse.

(4) Dust-and water-resistant triple-sealing construction
The Model CR 13VC 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.
Dust-resistant felt ring
It prevents dust from entering by way of the plunger (reciprocating shaft).
Dust-and water-resistant seal ring (made of heat-resistant rubber)
It prevents dust and waste water from entering by way of the plunger (reciprocating shaft).

(5) Comfortable double-molded (leostomer and polyamide resin) handle
The handle is nonskid and comfortably fits in the palm of a hand thanks to the double-molded construction
(glassfiber reinforced polyamide resin at the handle main body and leostmer at the grip). You can see the
excellence especially when you operate the Model CR 13VC wearing working gloves.

5-2. Optional Accessories
The cutting speed of the Model CR 13VC is substantially higher than that of the current Model CR 12V, 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. A very hard steel
called "DM05" (JIS: SKH51 or equivalent molybdenum containing high speed tool steel) or "Matrix II" (JIS: SKH59
or equivalent cobalt containing high speed tool steel) is used at the cutting edges, and a flexible steel for spring
material is used for the blade main body. So these BI-METAL blades are remarkably stronger than the HCS
blades.
(1) HCS blades
The blade numbers of HCS blades in Table 1 are engraved in the vicinity of the mounting position of each blade.
Select appropriate blades by referring to Tables 1 and 3 below.

Cut-off guide (L) permits easy cutting of mild steel pipes.
Cut-off guide (L) is applicable to the above specified saw blades only. Do not use it for the other short saw
blades. Check that the saw blade is not disengaged from the guide bar before operation. During cutting, be
careful not to disengage the saw blade from the guide bar. If the saw blade is disengaged from the guide bar,
the saw blade can be damaged.

7-3. Cutting Operation for Long Blade Life
The service life of a saw blade may vary depending on the operating conditions such as the type of cutting action,
pressing force, etc. Observing the following instructions can lengthen the service life of a saw blade, for reference.
< Explanation >
Heat generated in the cutting operation can significantly affect the service life of the saw blade. Continued cutting
operation with the saw blade heated to red hot can decrease the hardness of the saw blade because the cutting
edge is annealed. The saw blade is then worn out in a short time and nothing can be cut. The merits of moving
the saber saw up and down are described below.
The seesaw motion of the saw blade can minimize heating.
The effective cutting length of the blade is longer than that of an ordinary cutting operation. Thus, the service
life of the saw blade can be lengthened and the cutting speed becomes faster. Cutting wood in the same
manner can also make the cutting speed faster.
1
2
Application of undue force to the workpiece during the cutting operatation can heat up the saw blade and the
number of strokes can decrease, causing reduction of speed. Appropriate pressing force is about 4 to 5 kgf
(8.8 to 11 lbs.).
Do not apply undue force to the workpiece2
1 Move the saber saw handle up and down repeatedly during the cutting operation
The service life of a saw blade can be lenghtened by moving the saber saw handle up and down repeatedly
once or twice per second during the cutting operation.
