8. PRECAUTIONS IN SALES PROMOTION
8-1. Safety Instructions
In the interest of promoting the safest and most efficient use of the Model DS 12DVB 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. Handling instructions
Salespersons must be thoroughly familiar with the contents of the Handling Instructions in order to give pertinent
advice to the customer. In particular, they must have a thorough understanding of the precautions for use of the
cordless tools which are different from those of ordinary electric power tools.
(1) Before use, ensure that the unit is fully charged.
New units are not fully charged. Even if the units were fully charged at the factory, long periods of inactivity,
such as during shipping, cause the storage battery to lose its charge. Customers must be instructed to fully
charge the unit prior to use.
(2) Connect the Charger to an AC power outlet only.
Use of any other power source (DC outlet, fuel powered generator, etc.) will cause the Charger to overheat
and burn out.
(3) Do not use any voltage increasing equipment (transformer, etc.) between the power source and the Charger.
If the Charger is used with voltage higher than that indicated on the unit, it will not function properly.
(4) Conduct battery charging at an ambient temperature range of 0 ˚C --- 40 ˚C (32 ˚F --- 104 ˚F).
Special temperature sensitive devices are employed in the Charger to permit rapid charging. Ensure that
customers are instructed to use the Charger at the indicated ambient temperature range. At temperature
under 0 ˚C (32 ˚F) the thermostat will not function properly, and the storage battery may be overcharged. At
temperature over 40 ˚C (104 ˚F), the storage battery cannot be sufficiently charged. The optimum temperature
range is 20 ˚C --- 25 ˚C (68 ˚F --- 77 ˚F).
(5) The battery charger should not be used continuously.
At high ambient temperature, if over three storage batteries are charged in succession, the temperature of the
coils on the transformer will rise and there is a chance that the temperature fuse inserted in the interior of the
transformer will inadvertently melt. After charging one battery, please wait about 15 minutes before charging
the next battery.
(6) Do not insert foreign objects into the air vents on the Charger.
The Charger case is equipped with air vents to protect the internal electronic components from overheating.
Caution the customer not to allow foreign materials, such as metallic or flammable objects, to be dropped or
inserted into the air vents. This could cause electrical shock, fire, or other serious hazards.
