1. Safety instructions
In the interest of promoting the safest and most efficient use of the Model RB 14DSL cordless blower 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. 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 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 reserved, 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 overcharged.
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 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.
(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.
PRECAUTIONS IN SALES PROMOTION
-5-
(9) Do not attempt to disassemble the storage battery or the charger.
Special devices, such as a thermostat, are built into the storage battery and the 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.
(10) Disposal of the storage batteries
Ensure that all customers understand that the storage batteries should be returned to the Hitachi
Power Tool sales outlet or the authorized service center when they are no longer capable of being
recharged or repaired. If thrown into a fire, the battery may explode.
(11) Keep the battery out of dust.
• Protect the battery from being covered with dust during operation.
• Protect the battery from being covered with dust accumulated on the Model RB 14DSL during
operation.
• Do not leave the battery in a dusty area when not in use.
• Remove dust from the battery and store it separating from metallic parts such as screws and nails.

2. Precautions requiring particular attention during sales promotion
The cordless blower 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, there are certain precautions which require particular
attention. Salespersons must be thoroughly familiar with the following points to properly advise the
customer in the most efficient use of the tool.
A. Suggestions and precautions for efficient use of the tool
(1) Use the cordless blower for comparatively light work.
Because the Model RB 14DSL is battery-operated, the output of the motor in cordless blower is rather
low in comparison with conventional electric power tools. Accordingly, it is not suitable for continuous
blowing in succession which creates a heavy load. Salespersons should recommend conventional
electric power tools for such heavy work.
(2) Do not insert a foreign object into body.
A foreign object inserted through a hole may cause a failure. Please instruct customers to never insert a
foreign object into body.
(3) Avoid “Locking” of the motor.
Locking of the motor will cause an overload current that could result in burning of the motor and/or rapid
deterioration of the battery. Salespersons should advise the customer to immediately release the switch
and stop operation if the motor becomes locked.
(4) Variation in amount of work possible per charge
Although the nominal chargeable capacity of the storage battery used with the Model RB 14DSL is 3.0
Ah, the actual capacity may vary within 10% of that value depending on the ambient temperature during
use and recharging, and the number of times the batteries have been recharged. It should be noted that
other factors which may have a bearing on the amount of work possible per charge are the working
conditions and the operational skill of the user.
B. Suggestions and precautions for efficient use of the charger and the storage battery
Batteries may not be rechargeable immediately after use.
If the storage battery is exposed to direct sunshine for an extended period, of if the temperature of the
battery is 40 °C (104 °F) or higher immediately after it has been used in the tool, the pilot lamp may not light
up when the battery is connected to the Model UC 18YRSL charger. This is because the built-in thermostat
functions to stop the charging when the temperature of the storage battery reaches 40°C (104°F) or higher.
In such a case, the customer should be advised to place the battery in a shaded area with a good airflow,
and allow sufficient cooling before recharging. This phenomenon is common to all existing batteries which
employ temperature sensitive overcharge devices. The cooling time required before charging can be
accomplished varies from a few minutes to about 30 minutes, depending on the load, duration of use, and
ambient temperature.
