Note: When the retraction tank is made locally, fin-
ish it so that the welding bead does not protrude on
the inner surface of the tank. The tank guide will hit
the bead, causing motor burn-out. The gap between
the tank and tank guide is 1 mm. Also when install-
ing the tank, orient the welding bead so it faces the
port or starboard side.
