Precautions In Sales Promotion; Handling Instructions - Hitachi C 6DD Technical Data And Service Manual

8. PRECAUTIONS IN SALES PROMOTION

In the interest of promoting the safest and most efficient use of the Model C 6DD 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 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 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 24YFA charger provided with the tool.
Because of the batteries' rapid-charging feature (about 50 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 over and above that indicated on the unit, it will not function properly.
(5) Conduct battery charging at an ambient temperature range of 0 --- 4 ˚C (32 --- 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˚ --- 77˚F).
(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. 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.
(8) 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.
