Operation
Daily operation
Operation steps
(1) Check that the front door is closed.
(2) For dust explosion countermeasure (Simple explosion-proof
specification) models, ensure the explosion outlet port lid is not
displaced.
(3) Turn on the switch to start operation.
Shutdown
(1) Turn off the switch.
(2) Perform shaking after about two minutes and remove the collected
materials accumulated on the dust pan.
Precautions
The switch is equipped with an overload protection device:
If the dust is very fine, at the start of operation, a small amount of dust may leak
temporarily. If dust adheres properly to the filter cloth, there will be no leak. If leaking
does not cease, replace filter with the optional high-performance filter cloth:
Continual operation of the machine will clog the filter and decrease suction power.
Stop operation, shake the filter, and discharge the collected materials:
Shaking and collected materials removal during operation is not possible:
Since the dust pan is fixed with a spring, it catches when pulling it in and out. When
inserting, insert the pan until it clicks back into place.
Be careful not to allow too much collected materials in the dust box. Also, if too
much liquid is stored in the dustpan and spills out, it may leak from the front door.
When removing the collected material, use suitable protective equipment, such as
protective goggles, a dust mask, and gloves.
If using the machine with collected materials accumulated in the machine between
the workbench and the dustpan, the collected materials n may be ignited by sparks.
Perform a trial run and inspect according to instructions if using a machine that has
been in stored or that was shutdown and has not been operated for a long time.
Although the life of filter cloth varies depending on use time, characteristics of powder
dust and dust amount, the usual lifespan is 1 to 2 years. If the suction power is not
restored even after shaking, or shaking becomes heavy, replace the filter cloth.
Filter cloth damage should not occur with normal use, but if it is damaged, stop
operation and replace the filter cloth with a new one. Continuous use with a broken
the filter cloth may cause not only powder dust to leak and be released to the
atmosphere but also the blower to be damaged.
