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 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.
