7. PRECAUTIONS IN SALES PROMOTION

7-1. Safety Instructions

In the interest of promoting the safest and most efficient use of the Model CR 24DV by all 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 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 without 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 24YFB Charger provided with the tool.
Because of designed rapid-charging feature (about one hour), use of other battery chargers is hazardous.
(3) 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 burnt 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 over and above that indicated on the unit, it will not function properly.
(5) Conduct battery charging at an ambient temperature range of 0˚C --- 4 ˚C (32˚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 over 40˚C (104˚F), the storage battery cannot be sufficiently charged. The optimum
temperature range is 20 --- 25˚C (68˚F --- 77˚F).
(6) 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. After charging one battery, please charge the next battery after about a
fifteen-minute interval.
(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 inflammable objects, to be dropped or
inserted into the air vents. This could cause electrical shock, fire or other serious hazards.
(8) Do not attempt to disassemble the storage battery or the charger.
Special devices, such as a thermistor, 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.
