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 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.
Such inconvenience was a cause of inefficient operation because the operator kept using a dull blade without
replacing it with a new one, even though a saber saw blade is apt to wear out due to its applications.
The Model CR 13VA eliminates such inconvenience by adopting the Hitachi-original detachable mechanism
that enables one-hand mounting and removal of saw blades without the use of a wrench or other tools.
< Features of the Hitachi-original detachable mechanism >
The saw blade can be mounted and removed just by turning the holder sleeve.
The sleeve holder can be automatically secured in a released state by turning it all the way. In the
released state, the built-in spring force pulls the holder pin back to the correct position automatically. Thus,
saw blades can be smoothly replaced with one hand.
Competitors' products require two-hand operation.
Refer to the Handling Instructions and the leaflets for detailed information
about saw blade replacement.
