(4) Put a new spring in place. Also replace the washer, spring-adjustment nut, locknut and
guide plate removed in step (3) as well as the screw removed in step (2).
(5) Taking precautions against problems in vertical movement of the rod, secure the guide plate
to the chassis (with screws).
(6) Adjust the pressure of the spring.
First, x the bottom plate of the cleaning chamber (temporarily with tape) to where the
gasket makes slight contact with the bottom edge of the chamber.
Next, screw the spring-adjustment nut into the rod so the spring tightens as it contracts by
approximately 9 mm (pressure of spring: approximately 40 N {4 kgf}).
(7) Tighten the locknut.

6.5 Chemical Solution Cannot Be Fed into
Cleaning Chamber
Timer T2 may fail to come into action although the slider on the cylinder has reached the top end
of the cylinder barrel. Consequently, none of the chemical solution is forcibly fed into the cleaning
chamber (i.e., solenoid valve SV1 does not open). One of the reasons is an erroneous DETECT
UPPER LIMIT signal (or the signal is not present).
If this failure occurs, always proceed as follows: First make sure cleaning sequence is nished
and the slider on the cylinder is positioned at the bottom end. Then check the cable wired to the
terminal block for the limit switch.
WARNING
Electrical shock hazards:
Short-circuited cable between terminal 1 and 2 on the terminal box for the limit switch, an
electrical current of 24 VDC, 50 mA maximum passes.
lf any abnormality, such as a broken wire, is found, remedy it. lf you cannot point out any
abnormality in the wiring or localize the cause of failure, contact our sales ofce.
