7. PRECAUTIONS IN SALES PROMOTION
7-1. Safety Instructions
In the interest of promoting the safest and most efficient use of the Model CL 14DSL 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 in the use of the cordless (battery charger type) electric power tool 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 out of use, 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, use only the exclusive Model UC 18YRSL charger
provided with the tool. Because of the designed rapid-charging feature (about one hour), use
of other battery chargers is hazardous.
(3) Follow prescribed steps in using the Charger.
First connect the Type BSL 1430 storage battery to the Model UC 18YRSL charger, then plug
the charger into an AC outlet (ensuring that the voltage matches that indicated on the
unit). If this order is reversed, the charger may not function properly.
(4) Ensure the power source voltage is the same as that indicated on the name plate of the
charger. Use of any other power source (DC outlet, fuel powered generator, etc.) will
cause the charger to overheat and burn out.
(5) Do not use any voltage increasing equipment (transformer etc.) between the power
source and the charger. If the charger is used with voltage over and above that indicated on
the unit, it will not function properly.
(6) Conduct battery charging at an ambient temperature range of 0°C to 40°C (32°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 under 0°C (32°F), the thermostat will not function properly,
and the storage battery may be over-charged. At temperature over 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).
(7) The battery charger should not be used continuously.
At high ambient temperatures, 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 charge the next battery after about a fifteen-minute
interval.
(8) 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.
