PRECAUTIONS IN SALES PROMOTION

1. Safety instructions

In the interest of promoting the safest and most efficient use of the Models RB 14DL and RB 18DL cordless
blowers 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) When charging storage batteries, use only the exclusive Model UC 18YRL charger provided with
the tool.
Because of the designed rapid-charging feature (about 45 minutes), use of other battery chargers is
hazardous.
(3) 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.
(4) 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.
(5) Conduct battery charging at an ambient temperature range of 10°C - 40°C (50°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 10°C (50°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).
(6) 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.
(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 electrical shock, fire, or other serious
hazards.
