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.

    8. PRECAUTIONS IN SALES PROMOTION In the interest of promoting the safest and most efficient use of the Model C 14DMR 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 9: Caution Plates

    (10) Disposal of the storage battery. Ensure that all customers understand that storage batteries should be turned to a Hitachi Power Tool sales outlet or authorized service center when they are no longer capable of being recharged or repaired. If thrown into a fire, the batteries may explode, or if discarded indiscriminately, leakage of the cadmium compound contained in the battery may cause environmental pollution.
  • Page 10: Inherent Drawbacks Of Cordless Circular Saws Requiring Particular Attention During Sales Promotion

    (1) Do not overload the motor. As the Model C 14DMR 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.
