  • Page 4: Product Name

    1. PRODUCT NAME Hitachi Cordless Circular Saw, Model C 6DC 2. MARKETING OBJECTIVE Circular saws are highly sought in the United States and some other countries where a majority of houses are of 2 x 4 construction. While we have so far met this demand with our AC-powered saws, the need for cordless tools is growing for working on sites with no or few power supply facilities.

  • Page 5: Selling Point Descriptions

    The shape of the handle is an important consideration in designing an easy-to-use circular saw. The shape, angle and location of the Model C 6DC's switch handle is similar to those of AC-powered circular saws that are familiar to users, because of Hitachi's unique design of the battery holder. The figures and the table below give a comparison of switch handles between the Model C 6DC and maker C's saw.
  • Page 6 (4) Convenient spotlight for lighting blade edges and cutting lines The Model C 6DC is the first product in the portable circular saw industry equipped with a spotlight for lighting blade edges. The working efficiency is improved because the spotlight helps to align the saw blade with a premarked cutting line even in a dimly lit workplace.

    8. PRECAUTIONS IN SALES PROMOTION In the interest of promoting the safest and most efficient use of the Model C 6DC Cordless Circular 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 Caution Plate and Name Plate attached to each tool.

  • Page 11: Caution Plates

    (10) Disposal of the Model EB 18B battery. Ensure that all customers understand that Model EB 18B Batteries should be turned in to a Hitachi Power Tool sales outlet or authorized service center when they are no longer capable of being recharged or repaired.

  • Page 12: Inherent Drawbacks Of Cordless Circular Saws Requiring Particular Attention During Sales Promotion

    (1) Do not overload the motor. As the Model C 6DC is a battery-powered cordless circular saw, the motor's output and torque are less than those of ordinary AC-powered circular saws. Do not twist or thrust the main body during cutting. Otherwise, the motor becomes locked and will cause burning of the motor or deterioration of the battery.
