Caution: Before maintenance, be sure to turn the power off and
remove the power plug from the outlet.
Before using the tester, be sure to check the circulating solution. If the solution is dirty,
replace it as explained below. Even if the solution is not dirty, replace it at least once every
two years. In cold areas, use antifreeze. If the circulating solution freezes, the tester will be
damaged.

(2) Remove the circulating solution tank stay and take out the circulating solution tank.
(3) Remove the cap from the ciculating solution tank and tilt the tank to drain the circulating
solution (see Fig. 17).
(4) After draining the solution, secure the circulating solution tank as it was and pour in the
solution in the same manner to 2.3 Supplying Circulating Solution on page 15.
