1. Cautions in safety

The bowl of SELFJECTOR revolves at high speed, causing great centrifugal force to act. As erroneous handling causes great danger, handle with due cautions in operation, dismantling, assembling, maintenance and inspection, etc. in accordance with this manual.

Perform assembling perfectly
SELFJECTOR has many parts connected with nuts, bolts
and screws. When assembling it, make sure that they are fully tightened. Extreme care must be exercised to tighten the bowl nut, disc nut, clamp nut, vertical shaft cap nut, frame cover lock handle, etc. positively. Please note thoroughly that it is very dangerous to operate SELFJECTOR without tightening its parts firmly. Wih regard to such parts as bowl, etc. provided with tally mark, be sure to confirm that marks are in coincidence with each other.
On the other hand, if tally marks are misaligned when bowl nut, etc. were tightened, contact us or our service agent.

Stop immediately when vibration is great.
Though the vibration of Selfjector will differ depending on the effect of imbalance and besides the vibration of hull or the installing condition of Selfjector, the undermentioned Table shall be complied with Stop SELEFJECTOR immediately when vibration has become great. In that case, do not perform sludge discharge.
After confirming complete stop, proceed to dismantling, cleaning and inspection.

Inspection will be made at once

Vibration measurement shall be conducted in the frame part of SELFJECTOR (at point "A).
After confirming complete atop, loosen the parts.
After confirming that the bowl completely stopped revolving, loosen the parts and dismantle.
On the other hand, whether or not revolution has stopped completely can be confirmed at the gear pump and horizontal shaft conciliation (safety joint) or motor fan.

Handle parts carefully.
As SELFJECTOR is a precision machine, take due cautions in handling of the parts, etc. so as to avoid impact and high heat.
Take caution against corrosion and erosion periodically check for damage, if any, due to corrosion o,r erosion. With regard to unidentifiable points, contact us or our service agent.

(1) Before dismantling, be sure to switch off power to starter.
(2) When treating liquid different from the liquid originally planned to be treated please contact us or our service agent.
(3) Since the bowl has been adjusted in balance, it is preferrable to avoid replacement of bowl parts even in the case of the same model.
