(4) After the replenishment of industrial alcohol, attach the internal lid of the
solvent tank and tighten the cap securely.
Notice
Do not forget to put the internal lid back in place.
WARNING
When the cap is loose, the internal lid may blow off,
causing the industrial alcohol to drip out. The spill
may also cause a re.
Tighten the cap of the tank securely.
Note
If air enters the tube running between the solvent tank and the discharge nozzle,
the cleaning solvent may not be discharged soon.
In this case, discharge a little amount of alcohol to let the air escape, using the
