8. PRECAUTIONS IN SALES PROMOTION 8-1. Safety Instructions In the interest of promoting the safest and most efficient use of the Models DV 18DL and DV 14DL Cordless Impact Driver Drills 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 the Name Plate attached to each tool.
Page 17
(8) Disposal of the storage batteries Ensure that all customers understand that the storage batteries should be returned to the Hitachi power tool sales outlet or the authorized service center when they are no longer capable of being recharged or repaired.
8-2. Inherent Drawbacks of Cordless Impact Driver Drills Requiring Particular Attention During Sales Promotion The cordless impact driver drill offers many advantages; it can be used in places where no power source is available, the absence of a cord allows easy use etc. However, any cordless tool has certain inherent drawbacks. Salespersons must be thoroughly familiar with these drawbacks in order to properly advise the customer in the most efficient use of the tool.
(7) Precautions in the use of HSS drill bits For example, although the Model DV 18DL is designed for drilling capacities of 50 mm (2") in wood, and 13 mm (1/2") in aluminum and mild steel, this capability is not as efficient as conventional electric power tools. In particular, when drilling through aluminum material with a 13 mm (1/2") drill bit, the drill tends to become locked when the drill bit penetrates through the material.
10. REPAIR GUIDE Be sure to remove the storage batteries from the main body before servicing. Inadvertent triggering of the switch with the storage battery connected will result in danger of accidental turning of the motor. 10-1.
