4) Kowa is not liable for malfunctions and/or damages resulting from maintenance and/or repairs using parts
other than repair parts specied by Kowa.
5) The input voltage should always be maintained within ± 10% of the rated voltage.
6) Do not turn on the ash lamp and adjust photography light intensity at the same time.
7) Wait for approx. 1 minute until the instrument has safely started up.
8) Do not turn the main power ON and OFF in succession. Allow an interval of at least 10 seconds before
turning the main power ON and OFF.

4. Disposal precautions
When disposing this instrument, applicable federal, state, and local regulations must be observed. Ensure
that disposal is handled by a licensed industrial waste disposal contractor in accordance with the applicable
regulations and ordinances.
5. Replacement of the Aluminum Electrolytic Capacitor
The aluminum electrolytic capacitor for the ash lamp, which is used in the power supply section of this
instrument, is a component requiring regular replacements. The useful life of this type of components
may be signicantly reduced depending the frequency and conditions in which this instrument is used. If
the capacitor is used beyond its useful life, its electrolytic solution may leak or drain, which can result in
abnormal odor, smoke, bursting sound, and other failures.
The design life of the capacitor is 50,000 flashes when used in an ambient temperature of 25°C.
This is, however, only a guideline, and the capacitor may need to be replaced earlier depending on the
usage environment. In order to ensure safe and stable operation of this instrument, early replacement
of the aluminum electrolytic capacitor is recommended. Replacement of components requiring regular
replacement, such as aluminum electrolytic capacitor, is supported as a paid service. For more information
about replacement of such components, please contact Kowa or your Kowa dealer.
