8. PRECAUTIONS IN SALES PROMOTION 8-1. Safety Instructions In the interest of promoting the safest and most efficient use of the Model FDS 12DVA Cordless Driver Drill 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. A.
(8) Do not attempt to disassemble the Storage Battery or the Charger. Special devices, such as a thermostat, are built into the storage battery and charger to permit rapid charging. Incorrect parts replacement and/or wiring will cause malfunctions which could result in fire or other hazards. Instruct the customer to bring these units to an authorized service center in the event repair or replacement is necessary.
8-2. Inherent Drawbacks of Cordless Driver Drills Requiring Particular Attention During Sales Promotion The cordless 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. A.
(6) Precautions in the use of HSS Drill Bits Although the Model FDS 12DVA is designed for drilling capacities of 21 mm (13/16") in wood, and 15 mm (19/32") in aluminum, and 12 mm (15/32") in mild steel, this capability is not as efficient as conventional electric power tools. In particular, when drilling through aluminum material with a 15 mm (19/32") 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 the danger of accidental turning of the motor. 10-1.
