- the temp gets lower than 30-40 degrees F.
- the device was dropped or was le unused for
long period of time.
- Charge the product.

Low or No water
pressure
The tip is clogged, the reservoir vents (rubber
packing that joins reservoir and main unit) are
clogged, an additive was used, cleaning was
insucient, preparation for use was insucient or
the charge level is low.
- Perform cleaning. (P. 11)
- Charge the product.
Tip Broken in Unit The product was dropped.
- Screw a metal screw into the end of the broken
tip.
- Hit eject button and remove screw. Tip will come

used for a long time.
- Perform cleaning or contact the YA-MAN Call
Center (P. 16).
Water leaks from
the bottom of the
