● Commercially available batteries cannot be used.
Order batteries from your dealer.
● To replace batteries, turn off the power and replace

(2) Battery replacement method
When "battery replacement" is displayed for "Setting

the batteries. Be sure to turn the compressor off
before replacing the batteries.
① Remove the mounting screws on the part where
the buttons are to the right of the LCD unit.

pressor in the openings provided in 2 locations on
the right side of the LCD unit and remove the LCD

carefully pull out the right side so it comes off the
operation panel from the right.
④ The batteries are mounted on the back of the LCD
unit. Unplug the batteries from the connector. The
batteries are held in place by double sided adhesive
tape.

(3) Precautions concerning disposal of old batteries
Either return used batteries to your dealer or
properly dispose of them through an industrial
waste disposal contractor in accordance with
the "Law concerning disposal and cleaning of
discarded materials."
Used batteries are furthermore shorted if the posi-
tive and negative terminals come in contact with each
other or come in contact other metal objects, and
could cause the batteries to produce heart, rupture or
catch fire. Do not expose the batteries to fire. Used
batteries cannot be recharged.
