Replacing the consumable parts
4.3 Long-term storage tasks
If the solvent pump is not used for extended periods (about 6 months or more), then it may dry out internally
and cause operating defects. The solvent path within the pump must be blocked to prevent this from happening.
The path blocking procedure is described below.

Blocking the solvent path
1
Remove the cleaner cover.
1. Loosen the two screws (enclosed by a
dashed line circle in the figure on the

Remove the joints.
Remove the joints from two locations, one
on the head side and the other on the tank
side from the shut-off valve joint. Use caution
because alcohol remaining in the hose will
come out when the joint on the head side is
removed.
1. Remove the head side joint in the bent
state as shown by the dashed line in the
figure on the right.
2. Prepare a container, free the bent
location and let the alcohol drain into
the container.
3. Remove the tank side joint and then
quickly point it upward to let the alcohol
in the hose return back to the tank.

Reattach the cleaner cover.
Reinstall the cleaner cover in the reverse of
the procedure that you removed it in step 1.
Place a ribbon on the outer side of the
cover so that others will know that the joints
were removed.

Resetting operation
Connect the hoses in the reverse of the "Blocking the
solvent path" procedure and refill with solvent by
referring to 4.2 "Refilling the solvent". When finished
refilling, operate the solvent pump to make sure it
operates correctly.
