8. PRECAUTIONS IN SALES PROMOTION

In the interest of promoting the safest and most efficient use of the Model C 14DMR Cordless Circular Saw 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.
8-1. Handling Instructions
Salespersons must thoroughly be 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 storage battery is fully charged.
New storage batteries are not fully charged. Even if the storage batteries 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 storage battery prior to use.
(2) When charging storage batteries, use only the exclusive Model UC 24YFA charger provided with the tool.
Because of the batteries' rapid-charging feature (about one hour), 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 over and above that indicated on the unit, it will not function properly.
(5) Conduct battery charging at an ambient temperature range of 0 --- 40 ûC (32 --- 104ûF).
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 0ûC (32ûF), the thermostat will not function properly, and the storage battery may be
over-charged. At temperature over 40ûC (104ûF), the storage battery cannot be sufficiently charged. The
optimum temperature range is 20 --- 25ûC (68û --- 77ûF).
(6) The battery charger should not be used continuously.
At high ambient temperatures, if more than 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 charge the next battery after
about a fifteen-minute interval.
(7) Do not use more than two batteries in succession.
If three or more batteries are used in rapid succession, the main body may become overheated, causing
possible motor or switch malfunction. After two batteries have been used, stop operation for about 15 minutes
to allow the main body to cool.
