PRECAUTIONS ON SALES PROMOTION

1. Safety Instructions

In the interest of promoting the safest and most efficient use of the Model DB 3DL2 Cordless Driver Drill by
all of our customers, it is very important when concluding a sale that the salesperson carefully ensure that
the buyer seriously recognizes the importance of the Handling Instructions, and fully understands the
meaning of precautions listed on the Caution Plate and Name Plate attached to each tool.
A. Handling instructions
Salespersons must be thoroughly familiar with the Handling Instructions in order to give pertinent advice to
the customer. In particular, they must have a thorough understanding of the precautions on using cordless
tools that differ 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) When charging storage batteries, only use only the dedicated Model UC 3SFL Charger provided
with the tool.
Due to the designed rapid-charging feature (of about 30 minutes), the use of other battery chargers is
hazardous.
(3) Connect the charger to an AC power outlet only.
The use of any other power source (e.g., DC outlet, fuel powered generator) will cause the charger to
overheat and burn out.
(4) Do not use any voltage-increasing equipment (e.g., transformer) between the power source and
the charger.
Using the charger with voltage higher than that indicated on the unit will result in malfunction.
(5) Conduct battery charging at an ambient temperature range of 10°C to 40°C (50°F to 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 below 10°C (50°F) the thermostat will not function properly, and the storage battery may be
overcharged. At temperature above 40°C (104°F), the storage battery cannot be sufficiently charged.
The optimum temperature range is 20°C to 25°C (68°F to 77°F).
(6) The battery charger should not be used continuously.
Charging more than three storage batteries in succession at high ambient temperature will raise the
temperature of transformer coils and the temperature fuse inserted inside the transformer may
inadvertently melt. After charging one battery, please wait about 15 minutes before charging the next
battery.
(7) 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 electric shock, fire, or other serious
hazards.
