•
Standing on the left hand side

tate counterclockwise. If in-

the corresponding motors.

sure plunger is not damaged.
Replace valve or cartridge.
•
Replace chain or adjust ten-
sion.

Slide a sheet of paper be-
tween the brush and the belt;
it should slide freely. If brush

til it clears the belt just
enough to slide the paper un-
derneath. Make sure the pa-
per clears at the lacing.
•
Check the welds on each end
of the drive roller. The shaft
may be turning but not the
