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.
PRECAUTIONS IN SALES PROMOTION
-5-
(8) Do not attempt to disassemble the storage battery or the charger.
Special devices, such as a thermostat, are built into the storage battery and 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.
(9) Disposal of the storage battery (Types BCL 1430 and EBL 1430 for the Model RB 14DL, EBM 1830
for the Model RB 18DL)
Ensure that all customers understand that the storage batteries Types BCL 1430 and EBL 1430 for the
Model RB 14DL and EBM 1830 for the Model RB 18DL 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.
B. Caution plate
The following cautions are listed on the name plate attached to each of the Types BCL 1430, EBL 1430 and
EBM 1830.
[ For Europe ]
[ For the U.S.A. and Canada ]
2. Inherent drawbacks of cordless blower 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, any cordless tool has certain inherent drawbacks.
Salespersons must be thoroughly familiar with these drawbacks in order 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 Models RB 14DL and RB 18DL are battery-operated, the output of the motor in cordless
blower is rather low in comparison with conventional electric power tools. Accordingly, they are not
suitable for continuous blowing in succession, which creates a heavy load. Salespersons should
recommend conventional electric power tools for such heavy work.
-6-
(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 batteries Types BCL 1430, EBL 1430 and
EBM 1830 is 3.0 Ah, the actual capacity may vary within 10% of that value depending on the ambient
temperature during use and charging, 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
If the Types BCL 1430, EBL 1430 and EBM 1830 storage batteries are exposed to direct sunlight for an
extended period or if the tool has just been operated for a long time, charging may not be possible if the
temperature of the battery is above 40°C (104°F). 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 and chargers which employ temperature sensitive
overcharge protection devices. The cooling time required before recharging can be accomplished varies
from a few minutes to about 45 minutes, depending on the load, duration of use, and ambient temperature.

Be sure to remove the storage battery from the main body before servicing. Inadvertent triggering of the
switch with the storage battery connected will result in danger of accidental turning of the motor.
1.Precautions in disassembly and reassembly
The [Bold] numbers in the description below correspond to the item numbers in the Parts List and the
exploded assembly diagram for the Models RB 14DL and RB 18DL.
1. Removal of the fan
Be sure to draw on work gloves before holding the Fan [15] to prevent injury to fingers. Remove the Nozzle
[22] from the main body. Remove the Tapping Screw D3.5 x 15 (Black) [18] and the Tapping Screw D3.5 x
20 [20] that secure Housing (L) [19] to the casing. Remove the Nut M6 [16] and pull out the Fan [15] from
the motor shaft.
2. Removal of the motor
After removal of the Fan [15], remove the Tapping Screw D3.5 x 15 [14] that secures the casing to Housing
(R) [9]. Remove the Machine Screw M4 x 10 [8] that secures the casing to the Motor [11], and remove the
Motor Plate [13]. Then the Motor [11] can be removed together with Motor Holder (A) [12]. In either case,
the Motor [11] can be removed by lightly tapping the end of Housing (R) [9] with a wooden hammer.
3. Disassembly of the power supply unit
Remove the Battery Holder [7] from Housing (R) [9]. The internal wires of the Micro Switch [2] and the
Motor [11] are soldered to the Battery Holder [7]. Unsolder and remove the internal wires.
