Cautions:

Aqueous cleaning not recommended.
Flow soldering not recommended; use reflow soldering.
Model TC33 is not designed to be used with flux - use care with flux when soldering.
It is not recommended to adjust the Model TC33X-1 past the effective rotary angle.
If an excessive force is applied to the sliding part (the operating shaft) when adjusting the resistance value, the sliding part may be deformed or broken.
